HD4048412 - 4-Bit Single-Chip Microcomputer

Description

The HD404849 series of HMCS400-series microcomputers is designed to increase program productivity and also incorporate large-capacity memory.

Each microcomputer has an LCD controller/driver, A/D converter, input capture circuit, 32-kHz oscillator for clock use, and four low-power dissipation modes.

Features

  • 35 I/O pins, including nine high-current pins (15 mA, max. ), eight pins multiplexed with LCD segment pins, and four pins multiplexed with analog input pins.
  • Four timer/counters.
  • Eight-bit input capture circuit.
  • Three timer outputs (including two PWM outputs).
  • Two event counter inputs (including one in which the detection edge is programmable).
  • Clock-synchronous 8-bit serial interface.
  • A/D converter (8 channels × 8 bits)  Operation.
