Product details

It runs at 16 MHz on an STM8A core with 16 KB of Flash program memory, 2K x 8 RAM, and 512 x 8 EEPROM. The device integrates peripherals including brown-out detect/reset, POR, PWM, and WDT, plus connectivity interfaces I²C, LINbus, SPI, and UART/USART. It is housed in a 48-LQFP surface-mount package with 38 I/O lines, operates from 3 V to 5.5 V, and is rated for -40 °C to 125 °C — suitable for under-hood automotive and industrial engine-bay environments.

AEC-Q100 grade and temperature range

The 125 °C upper limit covers under-hood locations and engine-bay thermal profiles. An OEM auditor will expect PPAP documentation; the AEC-Q100 listing satisfies that gate.

Memory footprint and field updates

16 KB Flash and 512 x 8 EEPROM provide enough storage for small control firmware with calibration tables. The EEPROM allows field parameter updates without wearing the Flash. Firmware updates over LIN or UART are feasible if the bootloader fits in the reserved Flash sector — plan the memory map early to avoid a respin.
