Is it possible decipher markings on the integrated circuit, tell from the part number, use default register values or otherwise determine which version of MC68F375 I have? The ordering information, here: MC68F375|32 Bit Microcontroller (MCU)|NXP, describes KMC68F375BGMZP33 as 'REV F SAMPLE' but doesn't obviously specify revision of the other parts, MC68F375BGMZP33 ,MC68F375BGMVR33R, MC68F375BGMVR33 or MC68F375MZP33R2.
I have MC68F375BGMZP33 parts (without a 'K' prefix) and the markings on one of the CPUs I have are:
MC68F375BGMZP33 - Part number
8J28H - This may relate to the chip/die revision
QQKE0809A - This may be related to a manufacturing date
It's important for me to know because the CMF FLASH requires very different erase/program algorithms for different revisions of the CPU's CMF FLASH, from the General Market Driver for CPU32 user manual v1.06:
| Part Revision | CMF Module Revision | Program/Erase Algorithm |
|---|
| 0, C, D, F | CMF 5 | 5.0 |
| F+ | CMF 5 Thick Tunnel Oxide | 5.1 |
| G,H | CMF 9 | 6.0, 6.1 |
Thank you in advance.
