Description

The STM8S003x value line 8-bit microcontrollers feature 8 Kbytes Flash program memory, plus integrated true data EEPROM. The STM8S microcontroller family reference manual (RM0016) refers to devices in this family as low-density. They provide the following benefits: performance, robustness, and reduced system cost.

Features

Core
• 16 MHz advanced STM8 core with Harvard architecture and 3-stage pipeline
• Extended instruction set

Memories

• Program memory: 8 Kbytes Flash; data retention 20 years at 55 °C after 100 cycles
• RAM: 1 Kbytes
• Data memory: 128 bytes of true data EEPROM; endurance up to 100 000 write/erase cycles

Clock, reset and supply management

• 2.95 to 5.5 V operating voltage
• Flexible clock control, 4 master clock sources:
- Low power crystal resonator oscillator
- External clock input
- Internal, user-trimmable 16 MHz RC
- Internal low power 128 kHz RC
• Clock security system with clock monitor
• Power management:
- Low power modes (wait, active-halt, halt)
- Switch-off peripheral clocks individually
• Permanently active, low consumption power-on and power-down reset

Interrupt management

• Nested interrupt controller with 32 interrupts
• Up to 27 external interrupts on 6 vectors

Timers

• Advanced control timer: 16-bit, 4 CAPCOM channels, 3 complementary outputs, dead-time insertion and flexible synchronization
• 16-bit general purpose timer, with 3 CAPCOM channels (IC, OC or PWM)
• 8-bit basic timer with 8-bit prescaler
• Auto wake-up timer
• Window watchdog and independent watchdog timers

Communications interfaces

• UART with clock output for synchronous operation, Smartcard, IrDA, LIN master mode
• SPI interface up to 8 Mbit/s
• I2C interface up to 400 Kbit/s

Analog to digital converter (ADC)

• 10-bit, ±1 LSB ADC with up to 5 multiplexed channels, scan mode and analog watchdog

I/Os

• Up to 28 I/Os on a 32-pin package including 21 high sink outputs
• Highly robust I/O design, immune against current injection

Development support

• Embedded single wire interface module (SWIM) for fast on-chip programming and non intrusive debugging
