Fujitsu Microelectronics Introduces the Industry’s First 16-Bit CAN MCU with Embedded Dual-Operation Flash Memory

Sunnyvale, CA, April 15, 2003 — Fujitsu Microelectronics America, Inc. (FMA) today introduced the industry’s first 16-bit microcontrollers with dual-operation flash memory.

Fujitsu’s new MB90890 series of 16-bit microcontrollers support the Controller Area Network (CAN) interface, now the standard protocol for vehicle network applications. The MCUs are the first built using Fujitsu's F2MC-16LX 16-bit microcontroller architecture, which incorporates the dual-operation flash memory in a single chip, enabling simultaneous read/write processing. The dual-operation flash represents a significant performance advantage over conventional MCU architectures, in which all data configurations need to be written and stored on an external EEPROM or other non-volatile memory when the device powers down.

The new MB90890 series employs Fujitsu's leading-edge flash-memory technology, with 64 KB of dual-operation memory in two banks, allowing data to be rewritten while a program is executing on the same chip. This capability eliminates the need for external memory chips, reduces total chip area and lowers costs. Dual-operation flash also eliminates the requirement for external storage, thus eliminating associated security issues.

In addition, the ample amounts of non-volatile memory included in the MCUs enable storage of data such as anticipated driving distances or typical seat positions for each driver. As this information is recorded, the vehicle can incorporate controls for improving driver or passenger comfort, safety or communications.

The new MB90890 series is compatible with a wide range of operating voltages from 3.5V to 5.5V. The devices incorporate a strict threshold for low input voltage, with tolerances ranging from 30 percent of VCC to 50 percent of VCC. This provides adequate margin for circuit design while enhancing the system's resistance to noise.

The MCUs include 2 Kbytes of RAM, with 64 Kbytes of flash memory. Timer functions are included, and both delayed and external interrupt are included. All members of the family include one CAN channel, two UARTs and eight AD converter channels. Minimum execution time is a fast 62.5 nanoseconds at 4MHz, while the operating temperature ranges from -40 degrees C to 105 degrees C.

“Fujitsu plans to expand its line of microcontrollers with embedded dual-operation flash memory, and remains committed to helping its customers build better products more economically through its F2MC line of system controllers, which offer simpler system design, reduced part counts, improved security and lower real-estate demands for automotive body-control applications and digital-entertainment companion applications,᾿ said Keith Horn, FMA’s vice president of marketing.

Price and Availability
Sample will be available in May 2003. Production quantities of the MB90F897 and MB90F897S are scheduled to be available in the third quarter of this year in 48-pin low-profile quad flat packages for $6 each in 10,000-unit volumes.
