Description
The HD404328 Series is an HMCS400-Series microcomputer designed to increase program productivity
and also to incorporate large-capacity memory. Each microcomputer has an LCD controller/driver, A/D
converter, and zero-crossing detection circuit. Each also has a 32.768-kHz oscillator and low-power
dissipation modes.
The HD404328 Series includes eight chips: the HD404324 and HD404324U with 4-kword ROM; the
HD404326 and HD404326U with 6-kword ROM; the HD404328 and HD404328U with 8-kword ROM;
the HD4074329 and HD4074329U with 16-kword PROM. The HD404324U, HD404326U, HD404328U
and HD4074329U are designed to reduce current dissipation in subactive mode and watch mode.
The HD4074329 and HD4074329U, which include PROM, are ZTAT
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.)
