STM8S903K3T6C

The STM8S903K3T6C is access line 8-bit microcontrollers offer from 8 Kbytes up to 32 Kbytes of program memory.It contains 6 internal registers which are directly addressable in each execution context, 20 addressing modes including indexed indirect and relative addressing and 80 instructions.

The features of STM8S903K3T6C can be summarized as:(1)Max fCPU: up to 16 MHz; (2)Advanced STM8 core with Harvard ; (3)architecture and 3-stage pipeline; (4)Extended instruction set; (5)RAM: Up to 2 Kbytes; (6)3.0 to 5.5 V operating voltage; (7)Clock security system with clock monitor; (8)Nested interrupt controller with 32 interrupts; (9)Up to 37 external interrupts on 6 vectors; (10)8-bit basic timer with 8-bit prescaler ; (11)Auto wake-up timer; (12)SPI synchronous serial interface up to 8 Mbit/s ; (13)I2C interface up to 400 Kbit/s.

The absolute maximum ratings of STM8S903K3T6C are:(1)Supply voltage (including VDDA and VDDIO)(1):-0.3V to 6.5V; (2)Input voltage on true open drain pins (PE1, PE2)(2): VSS-0.3V to 6.5V; (3)Input voltage on any other pin(2):VSS-0.3V to VDD+0.3V; (4)Variations between different power pins:50mV; (5)Variations between all the different ground pins:50mW.1. All power (VDD, VDDIO, VDDA) and ground (VSS, VSSIO, VSSA) pins must always be connected to the external power supply. 2. IINJ(PIN) must never be exceeded. This is implicitly insured if VIN maximum is respected. If VIN maximum cannot be respected, the injection current must be limited externally to the IINJ(PIN) value. A positive injection is induced by VIN>VDD while a negative injection is induced by VIN<VSS. For true open-drain pads, there is no positive injection current, and the corresponding VIN maximum must always be respected.
