ST72141K2M3

The ST72141K2M3 is designed as 8-bit MCU with electric-motor control, ADC, 16-bit timers, SPI interface.

ST72141K2M3 has nine features. (1)Memories: 8K program memory (ROM/OTP/EPROM), 256 bytes RAM. (2)Clock, reset and supply management: enhanced reset system; low voltage supply supervisor; 3 power saving modes. (3)14 I/O ports 14 multifunctional bidirectional I/O lines with: external interrupt capability (2 vectors), 13 alternate function lines, 3 high sink outputs. (4)Motor control peripheral: 6 PWM output channels; emergency pin to force outputs to HiZ state; 3 analog inputs for rotor position detection with no need for additional sensors; comparator for current limitation. (5)3 timers: two 16-bit timers with: 2 input captures, 2 output compares, external clock input, PWM and pulse generator modes, watchdog timer for system integrity. (6)Communications interface: SPI synchronous serial interface. (7)Analog peripheral 8-bit ADC with 8 input pins. (8)Instruction set: 8-bit data manipulation; 63 basic instructions; 17 main addressing modes; 8 x 8 unsigned multiply instruction; true bit manipulation. (9)Development tools full hardware/software development package. That are all the main features.

Some absolute maximum ratings of ST72141K2M3 have been concluded into several points as follow. (1)Its supply voltage would be 6.5V. (2)Its input voltage on true open drain pin would be from Vss-0.3V to 6.5V. (3)Its input voltage on any other pin would be from Vss-0.3V to Vdd+0.3V.
