Flash MCU Targets Household Appliances

An 8-bit microcontroller with built-in flash memory, the TMP86FS49 is optimized for controllers in large household appliances such as refrigerators, washing machines, dryers and air conditioners. The MCU incorporates a high-performance TLCS-870/C 8-bit core in combination with 60 KB of flash memory, 2 KB RAM, a 10-bit ADC and a number of peripheral interfaces. Maximum operating speed is 16 MHz. The MCU can be programmed in-system or in a bulk programmer. Flash memory includes a security feature that prevents a third party from reading a customer code. Peripherals include a 2-channel UART, two channels of fast serial I/O, an I2C channel, and two timer/counter channels. Normal operation (no write operations) power supply voltage is 2.7 to 5.5V. Three packaging options are available: a plastic 64-pin QFP, plastic 64-pin LQFP; and a plastic 64-pin SDIP. Sample pricing is $6.78 each/1,000.
