Datasheet

- production data

Features

 Operating conditions

– Operating power supply: 1.65 V to 3.6 V

– Temperature range: –40 °C to 85 °C

 Low power features

– 4 low power modes: Wait, Active-halt with

AWU (1 µA), Active-halt with ProxSense™

(10 µA with scan every 200 ms),



Halt (0.4 µA)

– Dynamic power consumption: 150 µA/MHz

– Fast wakeup from Halt mode: 4.7 µs

– Ultra-low leakage per I/O: 50 nA

 Advanced STM8 Core

– Harvard architecture with 3-stage pipeline

– Max freq.16 MHz,16 CISC MIPS peak

 Memories

– Up to 16 Kbyte of Flash program including

up to 2 Kbyte of data EEPROM

– Error correction code (ECC)

– Flexible write and read protection modes

– In-application and in-circuit programming

– Data EEPROM capability

– 4 Kbyte of static RAM



Clock management

– Internal 16 MHz factory-trimmed RC

– Internal 38 kHz low consumption RC

driving both the IWDG and the AWU

 Reset and supply management

– Ultra-low-power, ultra safe power-on reset/

power-down reset

 Interrupt management

– Nested interrupt controller with software

priority control

– Up to 22 external interrupt sources

 I/Os

– Up to 23 with 22 mappable on external

interrupt vectors

– I/Os with programmable input pull-ups, high

sink/source capability

 ProxSense™ patented acquisition technology

with up to 300 touch sensing channels (20

receiver/transmitter channels and 15

transmitter channels) supporting projected

capacitive acquisition method suitable for

proximity detection.

 Timers

– Two 16-bit general purpose timers (TIM2

and TIM3) with up and down counter and

two channels (used as IC, OC, PWM)

– One 8-bit timer (TIM4) with 7-bit prescaler

– Independent watchdog

– Window watchdog

– Auto-wakeup unit

– Beeper timer with 1, 2 or 4 kHz frequencies

 Communication interfaces

– SPI synchronous serial interface

–Fast I2C Multimaster/slave 400 kHz

– USART with fractional baud rate generator

 Development support

– Hardware single wire interface module

(SWIM)

– In-circuit emulation (ICE)
