【STM8S003/STM8S005/STM8S007 超值系列 】

The STM8S Value line offers the best price/performance ratio among all our 8-bit microcontrollers.

Many consumer and large-volume industrial electronic devices require basic MCU functionalities and competitive pricing. Compared to existing low-cost MCUs, the STM8S Value line goes a step further, featuring outstanding performances, close to the STM8S Access and Performance lines, at a budget price.

All STM8S Value line microcontrollers are fully compatible with the existing STM8S product portfolio, sharing the same IPs, key parameter performance and development tools.

The STM8S001 expands our product portfolio in smaller pin count packages. Housed in a small industry-standard SO8 package, the new STM8S001 offers an outstanding set of features with top-notch core processing speed, system control, memory size, communication peripherals, and analog functions.

【STM8S003F3】

Mainstream Value line 8-bit MCU with 8 Kbytes Flash, 16 MHz CPU, integrated EEPROM

The STM8S003F3/K3 value line 8-bit microcontrollers offer 8 Kbytes of Flash program memory, plus integrated true data EEPROM. They are referred to as low-density devices in the STM8S microcontroller family reference manual (RM0016).

The STM8S003F3/K3 value line devices provide the following benefits: performance, robustness and reduced system cost.

Device performance and robustness are ensured by true data EEPROM supporting up to 100000 write/erase cycles, advanced core and peripherals made in a state-of-the-art technology at 16 MHz clock frequency, robust I/Os, independent watchdogs with separate clock source, and a clock security system.

The system cost is reduced thanks to a high system integration level with internal clock oscillators, watchdog, and brown-out reset.

Full documentation is offered as well as a wide choice of development tools.
