Product details

It runs at 16 MHz, with 8 KB of Flash program memory, 1K x 8 RAM, and 640 x 8 EEPROM. A 7-channel 10-bit ADC is integrated, and the oscillator is internal, saving a crystal on the BOM.

NRND status — plan the transition

This means STMicroelectronics is phasing out the part; new production designs should not start with this order code. Existing BOM lines can still be filled through independent distribution while stock lasts, but a replacement plan is advisable.

20-TSSOP footprint and supply rails

The MCU comes in a 20-TSSOP package (4.40 mm width), surface-mount only.

Frequently asked questions

Is STM8AF6223PCAX obsolete or NRND?

It is not fully obsolete, but STMicroelectronics is phasing it out. Existing BOM lines can still be supplied through surplus or broker channels while inventory lasts.

What is the replacement for STM8AF6223PCAX?

An official replacement order code is not listed in the available records. A pin-compatible alternative within the STM8A family — same 20-TSSOP footprint, same peripheral set — should be evaluated. Contact a sourcing specialist to cross-reference current STM8A offerings.

Is STM8AF6223PCAX automotive grade AEC-Q100?

Yes, the STM8AF6223PCAX is part of the Automotive, AEC-Q100 series, qualified for automotive applications.

What are the specifications of STM8AF6223PCAX?

It is an 8-bit MCU with a 16 MHz core, 8 KB Flash, 1K x 8 RAM, and 640 x 8 EEPROM. Peripherals include brown-out detect, POR, PWM, WDT, I²C, LINbus, SPI, UART/USART, and a 7-channel 10-bit ADC.
