For existing production, the NRND status means you have a window to secure final lifetime buys through independent distribution. ## CAN, 150°C, and 80-LQFP — what each rating means for the BOM The CAN 2.0B controller is the key connectivity feature — it lets this MCU talk directly on automotive powertrain and body networks without an external CAN transceiver (though you still need a transceiver for the physical layer). The 150°C operating temperature is the headline environmental spec: it covers under-hood, engine-bay, and transmission environments where standard 85°C or 105°C parts would fail.","metaTitle":"ST STM8AF52AATDY 8-bit MCU, 128KB Flash, AEC-Q100, 150°C","metaDescription":"STM8AF52AATDY automotive 8-bit MCU. 24MHz core, 128KB Flash, 6K RAM, 2K EEPROM, CAN 2.0B, 80-LQFP, -40 to 150°C.
