SGS-Thomson has launched a family of 8-bit microcontrollers based on an architecture that up to now had been used only internally to produce application-specific devices for PC monitors, remote controls, CD players, and car radios. The new ST72 core can run at double speed, comes in one-time-programmable versions, and offers low-voltage detection and high electrical noise immunity. On-chip memory ranges from 128 to 1,024 bytes of RAM and 4 kbytes of program memory to 32 kbytes or ROM/EPROM and 256 bytes of EEPROM. Peripherals include 8-bit multichannel DAC, SPI, I2C, USB, and CAN interfaces; a programmable watchdog timer, and one or two 16-bit timers. Applications include washing machines, food processors, power tools, and alarms. SGS-Thomson Microelectronics: Product Code 4276
