RENESAS HD4074224S01

These MCU's are CMOS 4-bit single-chip microcomputers with the same architecture as the HMCS400 Series. Each microcomputers incorporate ROM, RAM, I/O, and peripheral functions such as one or two timer/counters. Also, HD404222 Series has two-channel comparators, and a serial interface.

The HD404202 Series includes four chips: the HD404201 with 1-kword ROM and 5-V opcration; HD40L4201 with 1-kword ROM and low-voltage operation; HD404202 with 2-kword ROM and 5-V operation; HD40L4202 with 2-kword ROM and low-voltage Ooperation. The HD404222 Series includes three chips: HD404222 with 2-kword ROM and 5-V operation; HD40L4222 with 2-kword and low-voltage 0peration; HD4074224 with 4-kwordPROM.

The HD4074224, incorporating PROM, is a ZTATTM microcomputer which can dramatically shorten system development period and smooth the process from debugging to mass production. (The PROM programspecifications arethesameasforthe 27256.)
