Introduction

This document describes the features, pinout, mechanical data and ordering information of

the medium-density STM8AL313x/4x/6x and STM8AL3L4x/6x devices (microcontrollers

with up to 32-Kbyte Flash memory density). These devices are referred to as medium-

density devices in STM8L051/L052 Value Line, STM8L151/L152, STM8L162, STM8AL31,

STM8AL3L MCU lines reference manual (RM0031) and in STM8L and STM8AL Flash

programming manual (PM0054).

For more details on the whole STMicroelectronics ultra-low-power family please refer to

Section 3: Functional overview on page 13.

For information on the debug module and SWIM (single wire interface module), refer to the

STM8 SWIM communication protocol and debug module user manual (UM0470).

For information on the STM8 core, please refer to the STM8 CPU programming manual

(PM0044).

Note:

The medium-density devices provide the following benefits:

•

Integrated system

–

Up to 32 Kbytes of medium-density embedded Flash program memory

–

1 Kbytes of data EEPROM

–

Internal high speed and low-power low speed RC.

–

Embedded reset

•

Ultra-low power consumption

–

195 µA/MHZ + 440 µA (consumption)

–

0.9 µA with LSI in Active-halt mode

–

Clock gated system and optimized power management

–

Capability to execute from RAM for Low power wait mode and Low power run

mode

•

Advanced features

–

Up to 16 MIPS at 16 MHz CPU clock frequency

–

Direct memory access (DMA) for memory-to-memory or peripheral-to-memory

access.

•

Short development cycles

–

Application scalability across a common family product architecture with

compatible pinout, memory map and modular peripherals.

–

Wide choice of development tools

All devices offer 12-bit ADC, DAC, two comparators, Real-time clock three 16-bit timers, one

8-bit timer as well as standard communication interface such as SPI, I2C and USART. A

4x28-segment LCD is available on the medium-density STM8AL3Lxx line. Table 2: Medium-

density STM8AL313x/4x/6x and STM8AL3L4x/6x low-power device features and peripheral

counts and Section 3: Functional overview give an overview of the complete range of

peripherals proposed in this family.

Figure 1 shows the general block diagram of the device family.
