ST Microelectronics is extending choice and freedom for budget-conscious designers by introducing its new 8-bit STM8S001 microcontroller (MCU) in the economical
SO-8 package.
New 8-bit Microcontroller from ST Microelectronics Delivers Uniquely Flexible Feature Set in Space/Cost-Saving 8-Pin Package
Unlike most rivals, the STM8S001 has I2C, UART, and SPI interfaces, giving unusually versatile connectivity options. With a generous 8KB Flash memory, 1KB RAM, 128-byte EEPROM, and 3-channel 10-bit ADC also on-chip, it delivers key features of ST’s most popular STM8S003 MCU in a space-saving, low-pin-count device.
Fully specified from -40°C to125°C
Benefits: performance, robustness and reduced system cost.
The STM8S001 in 8-pin SO-8 is in production now, priced from $0.20 for orders of 1000 pieces. A Discovery kit will be available in Q4 2017. See here.
The system cost is reduced thanks to a high system integration level with internal clock oscillators, watchdog, and brown-out reset.
