Fujitsu Microelectronics America Launches MB89210 Series of General-Purpose 8-Bit MCUs with LIN-Compatible UART Interface

Sunnyvale, CA, April 23, 2003 — Fujitsu Microelectronics America, Inc. (FMA) today introduced two cost-effective 8-bit microcontrollers for automotive body-control module subsystems.

The MB89210 series of F2MC controllers includes Universal Asynchronous Receiver/Transmitter (UART) capabilities that support the Local Interconnect Network (LIN). LIN, along with the Controller Area Network (CAN), has emerged as a de facto, low-cost communications standard for in-vehicle networks.

The MB89210 series provides the ability to connect digital equipment such as audio speakers and minidisk players that work with a conventional UART in a LIN environment, so customers can design inexpensive, reliable automotive-grade local area networks. The LIN-compatible network can also expand network capability to automobile climate sensors, remote air-conditioning temperature and airflow controls, and other analog equipment.

The MCUs can operate using either internal or external clocks based on a crystal or ceramic resonator. This means that, if the device disconnects from an external oscillator source or if another failure on the resonator occurs, the controller can automatically switch to its internal source, so the CPU continues to function. The MB89210 series accepts a wide range of power sources from 3.5V to 5.5V, so the MCUs remain reliable even when the power supply fluctuates.

The minimum instruction execution time is 0.32 microseconds at 12.5 MHz. All versions of the series include a full complement of timers and an 8-channel A-to-D converter. Memory options include 512 Bytes of RAM, 16 Kbytes of ROM and 16 Kbytes of OTPROM.

“Two in-vehicle network technologies – CAN and LIN – have become widely accepted standards in automotive applications primarily to enhance safety and customer comfort,᾿ said Keith Horn, vice president of marketing for Fujitsu Microelectronics America. “Fujitsu has assumed a leadership position in developing a wide range of 8-bit, 16-bit and 32-bit MCUs for automotive applications that require either CAN or LIN capabilities.᾿

Packaging, Pricing and Availability
The MB89210 series, which is fabricated using Fujitsu’s 0.5-micron process technology, is packaged in a 30-pin Shrink Small Outline L-leaded Package (SSOP). Pricing starts at $1.50 for Mask ROM parts, and at $2.70 each in 10,000-unit quantities.
