Selection guide for STMicroelectronics STM8S and STM32 microcontrollers, detailing features, specifications, and product series.
This document provides a comprehensive selection guide for STMicroelectronics' STM8S 8‑bit and STM32 32‑bit microcontroller families. It lists the core architectures, memory options, peripheral sets, and package types to help designers choose the right device for their application.
Key highlights include the Cortex‑M3 core of STM32 devices with up to 72 MHz CPU speed, up to 512 KB flash, and a rich set of interfaces such as USB, CAN, and Ethernet. The STM8S line offers up to 20 MIPS performance, 4 KB‑128 KB flash, and a variety of timers and communication peripherals. The guide also describes the ST‑LINK emulator and the three‑in‑one development kit that combines STM8S and STM32 evaluation boards. This manual is written in Chinese.
| Flash memory (STM32 series) | up to 512 KB |
|---|---|
| CPU frequency (STM32F103) | 72 MHz |
| Core speed (STM8S) | 20 MIPS |
| Program memory (STM8S) | 4 KB‑128 KB |
STM32 devices can have up to 512 KB of flash memory.
It supports JTAG for all STM32F10x series and SWIM for all STM8S series.
STM32 offers an ARM Cortex‑M3 core, excellent real‑time performance, low power consumption, rich peripherals, and high integration.
