Description

This is the MDT2005BP, an EPROM-Based 8-bit micro-controller that utilizes a fully static CMOS design technology. It combines higher speeds and smaller size with the low power consumption and high noise immunity of CMOS. The chip includes 0.5 Kbytes of ROM and 32 bytes of static RAM in its on-chip memory system.
