Fujitsu Introduces New 8-Bit Microcontrollers for Digital Audio-Visual Systems, Household Appliances

Adds to Low-Power, High-Speed F2MC-8FX Family Developed to Meet Market Requirements

SUNNYVALE, Calif., March 14 / -- Fujitsu Microelectronics America, Inc. (FMA), a leading provider of low-power, high-speed microcontrollers for appliances and consumer electronics, today introduced a pair of new 8-bit MCUs for digital audio-video applications, portable radios, and household appliances.

The MB95F146 is a 32-pin microcontroller suitable for small, embedded applications like managing the power supply and remote controller of digital A/V equipment and systems. The MB95F156H comes in 48-pin and 52-pin packages, with an LCD display controller, making it an ideal design choice for portable equipment, remote control, air-conditioning systems and other applications. The MCUs expand the Fujitsu Flexible Microcontroller series, the F2MC-8FX family, which was introduced in March 2004 to deliver optimal power consumption and performance for the consumer electronics and appliance markets.

"New generations of appliances and consumer electronics equipment are using increasing numbers of digital microcontrollers that optimize their performance," said Akio Nezu, product manager for Fujitsu Microelectronics America. "Fujitsu has become a global industry leader by working closely with customers worldwide to deliver the best value and performance for these designs," he added.

Integrated ROM, RAM, A-D Channels

Each of the new MCUs includes 32kBytes flash ROM and 1 kilobyte of RAM, along with one-channel UART, eight channels of 10-bit analog-to-digital, up to eight external interrupts, a PPG (Programmable Pulse Generator) timer, and watchdog timers. The MB95F146 also incorporates 24 I/O ports, and runs on supply voltages ranging from 1.8V to 3.6V. The MB95F156H includes up to 39 I/O ports along with an LCD display controller, and operates on voltages between 2.5V and 5.5V. Both MCUs perform count operations at intervals up to one minute, providing the lowest possible power consumption in target applications. Both versions deliver execution times of 100ns/10 MHz.

Pricing and Availability

The MB95F146 is available now in 32-pin LQFPs, with prices starting at $1.76 each in 10,000-piece quantities. The MB95F156H comes in 48-pin and 52- pin LQFPs. Prices start at $2.54 each in 10,000-piece units. Fujitsu Microelectronics provides a complete evaluation board and a full set of development tools that can be used with any member of the F2MC-8FX microcontroller family, including these two new versions.
