Fujitsu Microelectronics America has added the MB91F467BA its MB91460 series of 32-bit microcontrollers for automotive applications. The MB91F467BA is designed for integrating several in-vehicle control area networks (CAN) or for controlling CAN, LIN and FlexRay mixed network gateways.

The MB91F467BA addresses the increasing speed and connectivity requirements that characterize vehicle applications, with the ability to control and integrate entire in-vehicle networks from within the head electronic control unit (ECU) that manages individual electronic components throughout the vehicle.

It operates at 80 MHz using a single 3.0 V to 5.5 V power supply and incorporates 1 MB flash with an 8 kB cache and 40 kB data RAM, plus five channels of DMA. It has an 8 x 16-bit free-run timer; an 8 x 16-bit reload timer, and 16 channels of an 8/16-bit PPG. For signal capturing, the chip provides a 32-channel 10-bit A/D converter, an 8-bit ICU, and 8-bit OCU channels. It supports a real-time clock and watchdog timer with separate clock source, and it includes an external SDRAM interface to meet high-memory bandwidth applications.

The MB91F467BA features a six-channel CAN controller, with each channel consisting of 32 message buffers; seven channels of LIN-capable UART, and two channels of I2C communication suitable for interconnection and gateway functionality, and to allow the MCU to control combinations of different in-vehicle networks.

The MB91F467BA is available in 144-pin LQFPs, with prices starting at $14.01 in volume quantities.
