1 A utomotive 16-bit Microcontroller F 2 MC-16FX Family 670/ 680/690/6A0/6B0/6C0 Series Twelve series of new products (53 products) for meter control and body control have been added to the lineup of our F 2 MC-16FX Family. These new products are automotive 16-bit microcontrollers that address recent market needs. Introduction In recent years, the popularization of electric cars and hybrid cars has become a matter that must be addressed immediately in order to prevent global warming. In addition, further reduction in power consumption is demanded in automotive systems. The demands for economical compact automobiles have been growing concurrently, leading to requests for solutions to realize further power consumption reduction, miniaturization, and cost performance improvement. To solve the problems of the increased ECU and man-hours required for development concurrent with the computerization of automobiles, movements to standardize automotive software programs have also grown, including AUTOSAR. However, redundant standardized specifications have caused a problem in ROM size for built-in applications, and the demands are high for AUTOSAR that is capable of flexible support for small-capacity 16-bit microcontrollers. To address these market demands, FUJITSU has added the MB96600 Series to our 16-bit microcontroller F 2 MC-16FX Family. This product addresses further reduction in power consumption, can comply with AUTOSAR, and has had a function added to reduce the number of external parts (E 2 PROM, low voltage detection/runaway detector).

2 Figure 1Lineup of F 2 MC-16FX Family products Product Features Figure 2 Image for Application of this Product in an Automobile Figure 1 presents the product lineup for the F 2 MC-16FX Family. MB96670, MB96680, MB96690, and MB966A0 deliver peripheral functions that are optimal for meter control. MB96610, MB96620, MB96630, MB96640, MB96650, MB96660, MB966B0, and MB966C0 deliver peripheral functions that are optimal for body control (air conditioners, Body Control Modules hereafter referred to as BCMs, and so forth). Figure 2 presents an application image for this product in an automobile. Low power consumption while maintaining the processing capability of high-performance 16-bit CPU core F 2 MC-16FX While the 32MHz operation of the conventional MB96300 Series required 1 wait for Flash memory access, the MB96600 Series addresses no-wait 32MHz operation by optimizing the Flash memory interface. This has resulted in approximately 25%performance improvement compared to the conventional 2

3 MB96300 Series at 32MHz operation. In addition, the adoption of ultralow leak processing technology has realized an approximately 30%reduction in the current consumption at 32MHz operation compared to the conventional MB96300 Series. This product achieves low current consumption operation while maintaining high processing performance. It is therefore optimal for meter control in which support for AUTOSAR and low power consumption are demanded, as well as body control, including air conditioners and BCMs. Solution to reduce the software development period For the F 2 MC-16FX Family, FUJITSU offers a software package that is compliant with AUTOSAR R3.1, the specifications recommended by Herstellerinitiative Software (hereafter referred to as HIS), an automotive software standardization organization, thanks to the cooperation of Indian KPIT Cummins Infosystems Limited. Figure 3 presents a comparison of ROM size between the conventional AUTOSAR and the HIS-recommended AUTOSAR specification. The ROM size of this software package is optimized by following the HIS-recommended specifications while complying with the AUTOSAR specifications. This enables AUTOSAR to be introduced without worrying about the program size even with 16-bit microcontrollers with small ROM sizes. In this way, an improvement in system cost performance is realized. Solution for reduction of system cost as well as board area This product has standard built-in dual operation Flash memory. As shown in Figure 4, a dual operation Flash memory has a two-bank configuration. Because it is capable of writing/ erasing in one bank while executing a program in another, it can be used as a replacement for E 2 PROM. This will contribute to the reduction in the number of parts on the ECU board. Advantages of dual operation Flash memory E 2 PROM can be eliminated and a reduction in the built-in area on the board is possible. Data writing speed can be improved (typical: 25μs/word). As data, the program and so forth are maintained in the Flash memory inside the microcontroller; this will help prevent information leaks. Built-in assisting functions optimal for LIN communication used in body systems, including power window and mirrors This product has built-in assisting functions that are capable of reducing the software processing load, including header transmission/ reception and the checksum generation in LIN communication used in body systems such as power windows and mirrors.

4 Assisting functions in LIN communication Automation of LIN header transmission/reception Figure 5 presents the automation of LIN header transmission/reception. Whereas the conventional products required frequent software processing during LIN communication header transmission and reception using UART, this product has reduced the software processing load by automating this process. Automation of checksum generation/judgment Figure 6 presents the automation of checksum generation/judgment. Compared to the conventional products that required the calculation of LIN communication checksum with software, this product has reduced the software processing load by automatically generating/judging the checksum. Built-in assisting function to detect changes in the analog input necessary for body system sensor processing The A/D converter of this product has built-in assisting functions to detect the changes in the analog input required in the body system s sensor processing. Range comparator function to automatically determine the A/D conversion results Figure 7 presents the range comparator functions. By setting the upper and lower threshold values for comparison with the A/D conversion results in advance, whether the A/D conversion result falls within the range or not can be automatically judged using interrupts. In this way, it is possible to reduce the software processing load. This also enables automatic detection when air-conditioning control reaches the target value or when the battery voltage falls below the lower limit. Application Examples MB96670/680/690/6A0 Series (for meter control) Although there are various types of meter indications in recent models, this product has optimal built-in peripheral functions for meter control with an LCD panel. This product has 2 to 5 built-in channels of a stepper motor controller capable of controlling indicators such as the speedometer and the tachometer. It also has a segment-type LCD controller for ODO/trip indication Figure 5Automation of LIN Header Transmission/Reception Figure 6Automation of Checksum Generation/Judgment Figure 7Range Comparator Function 4

5 New Products (24seg 4com, 32seg 4com, 36seg 4com, and 44seg 4com), as well as a sound generator capable of generating waveforms as the sound source for winker sound. In addition, a built-in realtime clock capable of clock count using a 4MHz oscillator for microcontroller operation instead of a kHz crystal oscillator is included, making it optimal for meter control. Figure 8 presents a meter application example. 6B0/6C0 Series (for body control) Systems such as automobile air conditioning and BCM are controlled on the basis of switch input and information from the various sensors built inside the vehicle. The MB96630/640/ 650/660/6B0/6C0 Series has five or more built-in channels of serial interface and is capable of connection using several ECU and CAN/LIN networks. The series also has 20 or more built-in channels of A/D converter and can address sensor input processing, which is becoming more diverse in systems such as air conditioners and BCMs. Figure 9 presents an application example in an air conditioner. Development Environment This product adopts the single-wire on-chip debugging interface method that is compliant with JPwire, and was developed by the standardization organization JASPAR. It is a compact emulator that also addresses our 32-bit microcontroller FR81S Family. Communication with the target board is possible at a distance of up to 10m using a standard coaxial cable. Although conventional products require system evaluation by building the actual device on an actual vehicle after debugging using the ICE main unit and the evaluation chip for verification, it is possible to implement a single unit system evaluation and a vehicle-incorporated evaluation using the actual device with this product. This also enables the onboard rewriting of the built-in Flash memory using this interface.
