STMicroelectronics Flexes MCU Muscle, Launches Standard 32-bit ARM products http://www.stm.com/stonline/press/news/year2004/p1431p.htm
The STR71xF series features:
ARM7TDMI core with 32-bit and Thumb16-bit instruction sets, 3-stage pipeline, 32-bit ALU, and extensive debug facilities;
16k to 64kbytes SRAM;
128kbytes to 256kbytes of Flash memory with fast random access time:
Up to 48MHz and 0 wait states with acceleration;
Up to 30MHz and 0 wait states without acceleration, and with no penalty on context switch and branching. This allows deterministic behaviour in real-time applications.
Up to 10 communication interfaces including I2C, SPI, UART, CAN, and USB, HDLC, MMC, and Smart Card interface;
4 Timers, Real Time Clock, and Watchdog Timer;
4 low-power modes;
Embedded regulator allowing a single 3.3V power supply;
12-bit ADC;
Up to 48 I/Os;
JTAG Debug Interface;
Industrial temperature range of -40°C to +85°C;
A small, low pin-count TQFP64 package without compromising feature availability, or a TQFP144 package with external memory support.
