The MB91F467B includes six C-CAN controllers and seven LIN-UARTs, backed up by 40Kbyte data RAM and 1088Kbyte of flash memory with readout protection.
The combination of features supports the robust computing power and high integration required in advanced automotive designs, such as automotive gateways, body-control applications and central controller systems.
In addition, the controller's external bus interface can be connected to Fujitsu's graphics controllers for use in building full-featured dashboards, driver information, and advanced driver-assistance systems.
'The new MB91F467B microcontroller includes all the critical features required by our automotive customers', says Akio Nezu, Senior Manager of the Embedded Solutions Business Group, Fujitsu Microelectronics America.
'It delivers the efficient data collection, data processing, and distribution that are essential to these designs, along with important power-saving and security features'.

The MB91F467B includes a 100MHz PLL clock circuit that minimises power consumption by dynamically switching off unused clock trees.
An integrated 32kHz sub-clock oscillator used in conjunction with standby modes such as 'stop' and 'sleep' adds power-saving capabilities.
Security and safety applications are supported by the internal clock supervisory circuit, which automatically switches to an internal RC-oscillator as backup in case of a main clock failure.
The MCU also provides flexible timer architectures and the ability to generate and capture high-precision signals, which are basic requirements for automotive systems.
The MB91F467B has 8 x 16bit, free-running timers; an 8 x 16bit reload timer; and 16 PPG channels.
For signal capturing, the chip has a 32-channel, 10bit ADC, eight ICU, and eight OCU modules.
The MB91F467B, which comes in a 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 during the second calendar quarter, accompanied by a full set of development tools such as starter kits, hardware- and software-debuggers, and the third-party supported automotive operating systems Autosar and Osek.
Both versions deliver execution times of 100ns/10MHz.
Sample pricing will start at $13 each.
