Trying to find the pinout and capacity of a M5M27400AK EPROM but I'm
not having any luck - can anyone help please?
Thanks

The Mitsubishi M5M27400AK device requires an M813 module.
Other devices requiring the same module are:
AM27C400-XX (AMD)
AM27C800-XX (AMD)
P87C251 (Intel microcontroller)
M5M27C102K (Mitsubishi)
TC574200D (Toshiba)
The AM27C400 and TC574200D parts are 4Mbit (512K x 8 or 256K x 16)
CMOS EPROMs:

Many thanks for that - so presumably the M5M27400AK is pin compatible
with the AM27C400 ?

microcontroller. This suggests that the programmer can account for any
non-significant differences.
If your part is installed on a PCB, then I would think that it
shouldn't be too difficult to trace the address and data buses back to
the CPU, or to a RAM with a known pinout. The supply pins should be
easy to determine, also.

I would presume so, but remember that the M813 module also accepts a
microcontroller. This suggests that the programmer can account for any

Sorry, thought I said - the original part is a mask ROM with the same
pinout as the AM27C400, that's why I wanted to check if the M5M27400AK
is the same as I know someone with a couple of spares (the original
mask ROM is missing, but I can program up an EPROM as I have the
relevant binary). So thanks to your help, I'll get hold of a
M5M27400AK and give it a go.
