The MCU is based on ST’s efficient STM8 16MHz 8-bit core and state-of-the-art peripherals that include a 10-bit ADC, two 16-bit capture/compare timers, an 8-bit general-purpose timer, UART, SPI and I2C, and 8K Flash, 1KB RAM, and 640B of data EEPROM provide plentiful on-chip storage for Access Line target applications.
The 20-pin UFQFPN20 package is the smallest in the current STM8S range, and is specified at 125°C. Its space-efficient 3mm2 outline has 16 user I/Os providing access to the powerful integrated microcontroller features. In addition, the wide operating-voltage range of 2.95-5.5V gives flexibility to interface easily with legacy 5V circuitry or with lower-voltage low-power logic.
The STM8 microcontrollers benefit from innovative implementation of the 125°C test flow at the wafer electrical test stage rather than after packaging. This has allowed continued use of proven high-parallelism final-test technology without modification to integrate high-temperature testing.
The STM8S103F3U3 is available immediately, priced from $0.46 for orders of 1000 units.
