ST ST10F269

ST10F269 Description générale

INTRODUCTIONThe ST10F269 is a derivative of the STMicroelectronics ST10 family of 16-bit single-chip CMOS microcontrollers. It combines high CPU performance (up to 20 million instructions per second) with high peripheral functionality and enhanced I/O-capabilities. It also provides on-chip high-speed single voltage Flash memory, on-chip high-speed RAM, and clock generation via PLL.ST10F269 is processed in 0.35µm CMOS technology. The MCU core and the logic is supplied with a 5V to 3.3V on chip voltage regulator. The part is supplied with a single 5V supply and I/Os work at 5V.■ HIGH PERFORMANCE 40MHz CPU WITH DSP FUNCTION   – 16-BIT CPU WITH 4-STAGE PIPELINE   – 50ns INSTRUCTION CYCLE TIME AT 40MHz MAX CPU CLOCK   – MULTIPLY/ACCUMULATE UNIT (MAC) 16 x 16-BIT MULTIPLICATION, 40-BIT ACCUMULATOR   – REPEAT UNIT   – ENHANCED BOOLEAN BIT MANIPULATION FACILITIES   – ADDITIONAL INSTRUCTIONS TO SUPPORT HLL AND OPERATING SYSTEMS   – SINGLE-CYCLE CONTEXT SWITCHING SUPPORT■ MEMORY ORGANIZATION   – 256K BYTE ON-CHIP FLASH MEMORY SINGLE VOLTAGE WITH ERASE/PROGRAM CONTROLLER.   – 100K ERASING/PROGRAMMING CYCLES.   – UP TO 16M BYTE LINEAR ADDRESS SPACE FOR CODE AND DATA (5M BYTES WITH CAN)   – 2K BYTE ON-CHIP INTERNAL RAM (IRAM)   – 10K BYTE ON-CHIP EXTENSION RAM (XRAM)■ FAST AND FLEXIBLE BUS   – PROGRAMMABLE EXTERNAL BUS CHARACTE RISTICS FOR DIFFERENT ADDRESS RANGES   – 8-BIT OR 16-BIT EXTERNAL DATA BUS   – MULTIPLEXED OR DEMULTIPLEXED EXTERNAL ADDRESS/DATA BUSES   – FIVE PROGRAMMABLE CHIP-SELECT SIGNALS   – HOLD-ACKNOWLEDGE BUS ARBITRATION SUPPORT■ INTERRUPT   – 8-CHANNEL PERIPHERAL EVENT CONTROLLER FOR SINGLE CYCLE INTERRUPT DRIVEN DATA TRANSFER   – 16-PRIORITY-LEVEL INTERRUPT SYSTEM WITH 56 SOURCES, SAMPLING RATE DOWN TO 25ns■ TIMERS   – TWO MULTI-FUNCTIONAL GENERAL PURPOSE TIMER UNITS WITH 5 TIMERS■ TWO 16-CHANNEL CAPTURE / COMPARE UNITS■ A/D CONVERTER   – 16-CHANNEL 10-BIT   – 4.85µs CONVERSION TIME AT 40MHz CPU CLOCK■ 4-CHANNEL PWM UNIT■ SERIAL CHANNELS   – SYNCHRONOUS / ASYNCHRONOUS SERIAL CHANNEL   – HIGH-SPEED SYNCHRONOUS CHANNEL■ TWO CAN 2.0B INTERFACES OPERATING ON ONE OR TWO CAN BUSSES (30 OR 2x15 MESSAGE OBJECTS)■ FAIL-SAFE PROTECTION   – PROGRAMMABLE WATCHDOG TIMER   – OSCILLATOR WATCHDOG■ ON-CHIP BOOTSTRAP LOADER■ CLOCK GENERATION   – ON-CHIP PLL   – DIRECT OR PRESCALED CLOCK INPUT■ REAL TIME CLOCK■ UP TO 111 GENERAL PURPOSE I/O LINES   – INDIVIDUALLY PROGRAMMABLE AS INPUT, OUTPUT OR SPECIAL FUNCTION   – PROGRAMMABLE THRESHOLD (HYSTERESIS)■ IDLE AND POWER DOWN MODES■ SINGLE VOLTAGE SUPPLY: 5V ±10% (EMBEDDED REGULATOR FOR 3.3 V CORE SUPPLY).■ TEMPERATURE RANGE: -40 +125°C■ 144-PIN PQFP PACKAGE
