DESCRIPTION

The DMC42P2008 is a system evaluation LSI having a build in One-Time-Programming circuit.

A programming and verification for the internal EPROM is achieved by using a adaptor socket.

The function of this device is exactly same as the DMC42C2008 with programming of internal EPROM.

The DMC42P2008 is the OTP version of the DMC42C2008 with replacement of MASK to EPROM as

as an internal ROM.
