It runs at 16 MHz with 8 KB Flash, 2 KB RAM, and 1 KB EEPROM, and includes a 22-channel 12-bit ADC and a single 12-bit DAC. The wide supply range from 1.65 V to 3.6 V and the -40 to 125 °C temperature rating suit it for under-hood and chassis-domain modules such as body controllers, window lifts, or seat-position sensors.
Operates from 1.65 V to 3.6 V and -40 to 125 °C. Internal oscillator reduces external component count.
ST has classified the STM8AL3136UCX as NRND (Not Recommended for New Designs), meaning it is not yet discontinued but is on the path to end-of-life. Existing production can continue through the last-time-buy window; new designs should select a current automotive MCU.
No official successor order code is listed by ST. For new designs, migrate to a current STM8A or STM32 automotive MCU with similar peripheral set and package. Existing BOMs can source the NRND part through independent distribution against an RFQ.
The supply voltage range is 1.65 V to 3.6 V, covering single-cell battery operation and standard 3.3 V logic rails.
The STM8AL3136UCX comes in a 32-VFQFPN (5x5 mm) package with an exposed pad for thermal management.
