3 / 80 page  HD404339 Series Rev. 7.0 Sept. 1999 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. The HD404339 Series includes six chips: the HD404339 with 16-kword ROM; the HD4043312 with 12- kword ROM; the HD404338 with 8-kword ROM; the HD404336 with 6-kword ROM; the HD404334 with 4-kword ROM; the HD4074339 with 16-kword PROM. The HD4074339 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.) ZTAT ™: Zero Turn Around Time ZTAT is a trademark of Hitachi Ltd. Features • 54 I/O pins One input-only pin 53 input/output pins: 30 pins are high-voltage pins (40 V, max.) • On-chip A/D converter (8-bit × 12-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 Subclock: 32.768-kHz crystal oscillator |
