描述 Description

The HD404339 Series is 4-bit HMCS400-Series microcomputer with large-capacity memory designed to increase program productivity. Each microcomputer has an A/D converter, input capture timer, and a 32-kHz oscillator circuit for clock use all built in. They also come with high-voltage I/O pins that can directly drive a fluorescent display.
