Fujitsu announces a new 32-bit Flash Microcontroller with six CAN interfaces for automotive and industrial applications
Langen and Nuremberg, 13th February 2007 — Fujitsu Microelectronics Europe (FME) is expanding its family of 32-bit RISC-MCUs with the new MB91F467B. Designed in close co-operation with major automotive customers worldwide, the MB91F467B inherits the high-performance core of Fujitsu's proven MB91460 family, and incorporates powerful peripheral functions and features that support a wide range of automotive and industrial applications.
Modern automotive designs demand higher computing power combined with a high degree of integration. Efficient data collection, data processing and distribution are essential and need a large number of interfaces such as CAN and LIN as well as a large memory capacity. The MB91F467B easily addresses these requirements with six C-CAN controllers and seven LIN-UARTs backed-up by 40kB data-RAM and 1088kB of flash-memory with read-out protection.
A 100MHz PLL clock circuit minimises power consumption by dynamically switching off unused clock trees. Further power saving features include an integrated 32kHz sub-clock oscillator in conjunction with standby modes such as 'stop' and 'sleep'. Security and safety applications are supported by the internal clock supervisory circuit, which automatically switches to an internal RC-oscillator as back-up in the event of a main clock failure.
Flexible timer architectures as well as the capability to generate and capture high precision signals are basic requirements for automotive systems. The MB91F467B provides 8x16-bit free-running timers, an 8x16-bit reload timer and 16 PPG channels. Signal capturing is supported by a 32-channel, 10-bit ADC, eight ICU, and eight OCU modules.
Target applications for this new MCU include automotive gateways, body control applications and central controller systems. The external bus interface can be connected to Fujitsu's graphics controllers in order to build full-featured dashboards, driver information and advanced driver assistance systems.
The MB91F467B comes in an RoHS-compliant 144-pin QFP package, functions over the automotive temperature range and operates on a supply voltage of 3V to 5.5V via its internal voltage regulator.
Availability
Engineering samples will be available in Q2/07, accompanied by a full set of development tools such as starter kits, hardware- and software-debuggers and third-party supported automotive operating systems AUTOSAR and OSEK.
