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.
Hi,
Sorry the device marking information is quite senstive and we do not provide it to customer directly. If customer really need it, please contact the sales rep whom you bought the chip from and he will decide if the information been given.
