MBL8149H Datasheet (Fujitsu) - NMOS Single-Chip 8-Bit Microcomputer

MBL8149H, NMOS Single-Chip 8-Bit Microcomputer

The Fujitsu MBL8749 is an 8-bit single-chip microcomputer that uses a 2K x 8-bit Electrically Programmable Read Only Memory (EPROM) for program memory.

The EPROM can be erased by using an ultraviolet (UV) light source; thus, program memory for the MBL8749 can be changed as often as required.
