HD404316H - 4-bit HMCS400-series microcomputer

Download the HD404316H datasheet PDF. This datasheet also covers the HD404 variant, as both devices belong to the same 4-bit hmcs400-series microcomputer family and are provided as variant models within a single manufacturer datasheet.

General Description

The HD404318 Series is 4-bit HMCS400-series microcomputer with large-capacity memory designed to increase program productivity.

Each microcomputer has an A/D converter and input capture timer built in.

They also come with high-voltage I/O pins that can directly drive a fluorescent display.

Key Features

  • 34 I/O pins  One input-only pin  33 input/output pins: 21 pins are high-voltage pins (40 V, max. ).
  • On-chip A/D converter (8-bit × 8-channel).
  • Three timers  One event counter input  One timer output  One input capture timer.
  • 8-bit clock-synchronous serial interface (1 channel).
  • Alarm output.
  • Built-in oscillators  Ceramic or crystal oscillator  External clock drive is also possible HD404318 Series.
  • Seven interrupt sources  Tw.

HD404318 Series Rev. 6.0 Sept. 1998 Description The HD404318 Series is 4-bit HMCS400-series microcomputer with large-capacity memory designed to increase program productivity. Each microcomputer has an A/D converter and input capture timer built in. They also come with high-voltage I/O pins that can directly drive a fluorescent display. The HD404318 Series includes four chips: the HD404318 with 8-kword ROM; the HD404316 with 6kword ROM; the HD404314 with 4-kword ROM; the HD4074318 with 8-kword PROM. The HD4074318 is a PROM version ZTAT™ microcomputer. Programs can be written to the PROM by a PROM writer, which can dramatically shorten system development periods and smooth the process from debugging to mass production. (The PROM program specifications are the same as for the 27256.
