DESCRIPTION
The
μ
PD75P108B is a version of the
μ
PD75108 in which the on-chip mask ROM is replaced by one-time
PROM which can be written to once only, or EPROM which is capable of program write, erasure and rewrite.
Also, since the
μ
PD75P108B is capable of program write by a user, it can easily be exchanged with the mask
version, allowing evaluation at low voltage.
Detailed functional descriptions are shown in the following User’s Manual. Be sure to read for designations.
