HD404019R Series
Rev. 6.0
Sept. 1998
Description
The HD404019R series are HMCS400-series CMOS 4-bit single-chip microcomputers. Each device
incorporates a ROM, RAM, I/O, serial interface, and two timer/counters, and contains high-voltage I/O
pins including high-current output pins to directly drive fluorescent displays.
The HD404019R series includes four chips. The HD404019R and HD40L4019R are Mask ROM versions.
The HD4074019 and HD407L4019 are PROM versions. The HD40L4019R and HD407L4019 are low-
voltage operation versions.
