MBL8149H - NMOS Single-Chip 8-Bit Microcomputer

Description

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.

Features

• 2K x a-bit program memory (EPROM).
• 256 x 8-bit data memory (static RAM).
• a-level stack.
• a pairs of working registers.
• 27 I/O lines: Two a-bit I/O ports, one a-bit data bus, two test inputs, and one interrupt input.
• a-bit timer/counter.
• On-chip clock generator (or external clock source).
• Single-level interrupt.
• External pr. Qgram mode.
• Single-step operation.
• RAM retention in low-power standby mode.
