Description

The HD404054 Series and HD404094 Series are HMCS400-series microcomputers designed to increase program productivity with large-capacity memory. Each microcomputer has three timers, one serial interface, comparator, input capture circuit.

Features

• The differences between HD404054 Series and HD404094 Series

• 27 I/O pins and 8 dedicated input pins

• Three timer/counters

• Eight-bit input capture circuit

• Two timer outputs (including two PWM outputs)

• One event counter inputs (including one double-edge function)

• One clock-synchronous 8-bit serial interface

• Comparator (2 channels)

• Built-in oscillators

- Main clock: Ceramic or crystal oscillator (an external clock is also possible)

• Six interrupt sources

- Two by external sources

- Four by internal sources

• Subroutine stack up to 16 levels, including interrupts

• Two low-power dissipation modes

- Standby mode

- Stop mode

• One external input for transition from stop mode to active mode

• Instruction cycle time: 1 µs (fOSC = 4 MHz at 1/4 division ratio)

- 1/4, or 1/32 division ratio can be selected by hardware

• Two operating modes

- MCU mode

- MCU/PROM mode (HD4074054, HD4074094)
