HD4074008 - Hitachi Semiconductor

HD4074008 Two timer/counters

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. The HD404849 series includes the HD404848 with an 8-kword on.

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 voltage 2.7 V to 6.0 V
• LCD driver (32 segments × 4 commons)
• Built-in oscillators  Main clock: Can be driven by ceramic oscillator, crystal oscillator, .
