General Description
HD404019RFS General 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 lowvoltage operation versions.

Notes: Permanent damage may occur if these absolute maximum ratings are exceeded. Normal operation should be under the conditions of the electrical characteristics. If these conditions are exceeded, it may cause a malfunction or affect the reliability of the LSI. All voltages are with respect to GND.
1. Standard pins.
2. High voltage pins.
3. Total permissible input current is the total sum of input currents which flow in from all I/O pins to GND simultaneously.
4. Total permissible output current is the total sum of the output currents which flow out from VCC to all I/O pins simultaneously.
5. Maximum input current is the maximum amount of input current from each I/O pin to GND.
6. D0 to D3 and R3 to R8.
7. Maximum output current is the maximum amount of output current from VCC to each I/O pin.
8. R0 to R2.
9. D4 to D15.
10. Applied to HD4074019 and HD407L4019.
