RISC-based MCU for automotive applications
The MB91F467B is designed in co-operation with major automotive customers and includes powerful peripheral functions and features to support a wide range of automotive and industrial applications.
Automotive MCU boasts six lines of CAN
The MB91F467BA is specifically designed for integrating several in-vehicle Control Area Networks or for controlling CAN, LIN and FlexRay mixed network gateways.
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 40Kbyte data RAM and 1088Kbyte 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 subclock 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 backup 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 8x16bit free-running timers, an 8x16bit reload timer and 16 PPG channels.
Signal capturing is supported by a 32-channel, 10bit 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 3 to 5.5V via its internal voltage regulator.
Engineering samples will be available in Q2 2007, 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.
