MBL8149N - NMOS Single-Chip 8-Bit Microcomputer

Download the MBL8149N datasheet PDF. This datasheet also covers the MBL8149H variant, as both devices belong to the same nmos single-chip 8-bit microcomputer family and are provided as variant models within a single manufacturer datasheet.

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.

MBL8149H/N 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. Also included in the MBL8749 are: 256 x 8-bit static RAM, 27 I/O lines, an 8-bit timer/counter, and a clock generator. The device can be ordered in either of two speed versions: N-version for operation at 6MHz and the H-version for operation at 11 MHz. Foreither frequency, the operating temperature range is O°C to 70°C. The MBL8749 is fabricated using an N-channel, 2-layer polysilicon-gate MOS process.
