Product details

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.

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.

That means you can design it into new builds without worrying about a last-time-buy window closing. The MC9S08AC16MFJE is ROHS3 compliant.

Frequently asked questions

Can MC9S08AC16MFJE replace MC9S08AC16CJE?

The MC9S08AC16CJE is the commercial-temperature (0°C to 70°C) variant of the same die. 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.

What is the lead time for MC9S08AC16MFJE?

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 As an active NXP part, typical independent-distribution lead times range from a few weeks to stock-available, but we do not publish a number here because availability shifts.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.

Is MC9S08AC16MFJE compatible with a 32-LQFP footprint?

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.
