Fujitsu announces 32-bit Microcontroller with 1MB Embedded Flash for Automotive Applications

MB91F467D features 64kB RAM, 3 x CAN, 5 x LIN UART, 6 x SMC

Singapore, January 17, 2007  — Fujitsu Microelectronics Asia Pte Ltd (FMAL) today announced the first flash device of its new MB91460 series, specifically designed for next-generation automotive applications. The MB91F467D is a 0.18µm successor to the MB91F362G dashboard microcontroller (MCU), offering higher speed, more memory and additional features.

The MB91F467D is the second device in the MB91460 series now available for sampling and follows the MB91461, a ROMless device for infotainment. FMAL will continue to release additional variations of MB91460 MCUs with different peripherals, which will offer designers devices for a wide range of applications.

The MB91F467D includes 1088kB of Fujitsu’s proven embedded flash technology that features protected read-out. On-chip pre-fetch and flexible cache ensure best possible performance from this memory, which is connected to both the I-bus and F-bus. The MB91F467D offers 64kB of embedded RAM and the external bus interface (32-bit data, 26-bit addresses) can be used to connect external memory, e.g. SDRAM, burst-mode flash or Fujitsu Graphic Display Controller (GDC) for cluster graphics control application.

Each of the 3 CAN interfaces has its own set of 32 message buffers; 4 of the 5 LIN-UARTs are equipped with 16 Byte Rx and Tx FIFOs to speed up communication. 3 I2C modules complete the set of serial communication interfaces.

Compared to the MB91F362G, the variety of timers has also been enhanced. The MB91F467D implements 8 free-running timers as a time-base for 8 ICU and 4 OCU modules, 8 Reload timers, 3 Up/Down Counters and an RTC (Real-Time Clock) module, which can operate on the 4MHz main crystal, or on the 32kHz sub clock.

In addition to the 6 channels of stepping motor controller interfaces to control dashboard instruments, the set of pulse-generating modules contains 12 channels of 16-bit PPG, a sound generator and a PFM module. The on-chip PLL will create an internal operating frequency of up to 96MHz; again Fujitsu’s proven clock modulator is implemented to improve EMC behaviour.

The MB91F467DA version also features the following analogue functions: 24 channels of a 10-bit ADC and 1 alarm comparator input. Other improvements are a choice of I/O drive strengths, 2mA, 5mA or SMC drivers of 30mA. Various input levels are also included, such as automotive, CMOS Hysteresis and TTL. All inputs come with internal pull-up resistors, which allow unused pins to be left open. The MB91F467DA comes in a 208-pin lead-free (pure Sn pin plating) QFP package.

The microcontrollers function over the operating temperature range of -40 to +105°C and operate from a supply voltage range of 3V to 5.5V.

The MB91F467D will be supported by the Accemic MDE (monitor debug environment). Two starter kits are also available, one of which includes MB91F467D and Fujitsu’s FlexRay™ Communication Controller IC MB88121.

Both design support and full turnkey application development are offered by FMAL’s Microcontroller Applications Engineering team and Design centres.
