D80C48C064 single-chip 8-Bit CMOS Microcomputer IC 6V PDIP-40 Wide

Description

D80C48C064 single-chip 8-Bit CMOS Microcomputer 6V IC PDIP-40 Wide The D80C48C064 is NEC’s CMOS implementation of the 8-bit MCS-48 family — a compact single-chip microcomputer that integrates an 8-bit CPU, on-chip ROM (the C48 variant), a small internal RAM, I/O ports and an 8-bit timer/event counter. Its architecture and bus timing are compatible with industry-standard 8048/8080A peripherals, making it easy to use in legacy 8-bit embedded systems and to expand with external memory or I/O. Designed for low power, the device supports special low-power modes (Halt and Stop) for battery-operated equipment. Because D80C48C064 combines ROM (on the C48 variant), RAM (64×8), and up to 27 I/O lines in a single package, the uPD80C48C is ideal for standalone control applications where cost, board space and power consumption matter. The chip’s instruction set (≈97 instructions) and simple peripheral set (timer/event counter, two interrupts, crystal oscillator input) make it straightforward to program for tasks like keypad scanning, simple UI handling, remote controls, small appliances and other embedded controllers. Features: Single-chip 8-bit CPU with on-chip memory and I/O (C48 variant includes ROM). Hardware/software compatibility with 8048/8748/8035 family. On-chip timer / event counter and two interrupt sources. Multiple low-power modes (Halt, Stop). Easily expandable memory and I/O (bus compatible with 8080A/8085A peripherals). CMOS low-power technology, compact package options (DIP / miniflat).
