STM8L051F3P6TR Ultra-Low-Power 8-bit MCU | 16MHz STM8L Controller | TSSOP-20 | STMicroelectronics | Jaron

Product Overview

     The STM8L051F3P6TR belongs to STMicroelectronics' STM8L Value Line ultra-low-power series. Based on an enhanced STM8 CPU core, it utilizes a Harvard architecture and a three-stage pipeline, operating at a maximum frequency of 16 MHz, providing approximately 16 MIPS of processing performance while significantly reducing dynamic power consumption per MHz.

     This device integrates 8 KB of Flash program memory, 256 bytes of data EEPROM (with ECC error correction), and 1 KB of RAM, providing flexible read/write protection mechanisms suitable for storing critical information such as configuration parameters, metering data, and operation logs. In terms of power consumption, the STM8L051F3P6 supports five low-power modes: Wait, Low-power run, Low-power wait, Active-halt with RTC, and Halt. The typical current in Halt mode is only about 350 nA, and Active-halt + RTC is about 1.3 µA, making it ideal for long-life battery applications.

     The STM8L051F3P6TR, packaged in a TSSOP-20, provides up to 18 versatile I/O pins, all of which can be mapped to interrupt vectors. It operates stably over an industrial-grade temperature range of –40°C to +85°C, operating from a 1.8–3.6 V supply voltage, offering a cost-effective solution for compact, low-power control boards.
