It runs at a 40 MHz bus clock and carries 16 KB of Flash program memory with 1 KB of RAM. ## Temperature grade and environment Rated for -40°C to 125°C ambient, this MCU is built for environments where a commercial-grade part would fail: engine compartments, outdoor telecom cabinets, factory-floor enclosures near motors, or downhole instrumentation. The 32-LQFP package (7x7 mm) is a standard surface-mount footprint, easy to inspect and rework with basic tools — no hot-air station required for a swap if the board has a soldering iron and flux. ## 40 MHz — what it means for the control loop The 40 MHz core clock is the headline number for this 8-bit part. ## Memory sizing for firmware 16 KB of Flash and 1 KB of RAM fits a modest firmware image: a bootloader, a few communication stacks (I²C slave, SCI Modbus), and a control loop. ## Lifecycle and sourcing reality That means you can design it into new builds without worrying about a last-time-buy window closing. The MC9S08AC16MFJE is ROHS3 compliant.","metaTitle":"NXP MC9S08AC16MFJE 8-bit MCU, 40 MHz, 16 KB Flash, 32-LQFP","metaDescription":"NXP MC9S08AC16MFJE S08 8-bit MCU: 40 MHz core, 16 KB Flash, 1 KB RAM, -40 to 125°C, 32-LQFP.

The MC9S08AC16MFJE is the industrial-temperature (-40°C to 125°C) version. Electrically and functionally identical — same 40 MHz core, same 16 KB Flash, same 32-LQFP footprint. The MFJE suffix replaces the CJE in any environment that needs the extended temperature range. For a desk-top or climate-controlled application, the CJE is fine; for anything that sees outdoor or under-hood conditions, the MFJE is the correct fit."},{"question":"What is the lead time for MC9S08AC16MFJE?","answer":"Lead time is confirmed at quote time against an RFQ. As an active NXP part, typical independent-distribution lead times range from a few weeks to stock-available, but we do not publish a number here because availability shifts. Submit an RFQ for current lead time and pricing."},{"question":"Is MC9S08AC16MFJE compatible with a 32-LQFP footprint?","answer":"Yes. The MC9S08AC16MFJE is supplied in a 32-LQFP package (7x7 mm body). It fits any standard 32-LQFP land pattern with 0.8 mm pitch. The supplier device package is 32-LQFP (7x7), so the footprint is consistent across the S08AC16 series in this package option."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/nxp/MC9S08AC16MFJE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/nxp/MC9S08AC16MFJE when reusing this data.
