HD404326

HD404328 Series Rev. 6.0 Sept. 1998 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™ microcomputers that 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.) Features 4,096-word ...
