NEC D8748HD 8-Bit Microcontroller 1K×8 EPROM 5V 100mA PDIP-40

NEC D8748HD 8-Bit Microcontroller 1K×8 EPROM 5V 100mA PDIP-40

The D8748HD is a high-performance, self-sufficient 8-bit parallel microcontroller fabricated using the advanced N-channel silicon gate HMOS-E process. Designed to function as a complete computer on a single chip, it integrates program memory, data memory, I/O lines, and an oscillator into one 40-pin package. This component is an ideal solution for efficient control-oriented tasks and arithmetic processing, offering the flexibility of erasable EPROM for prototyping and production.

Features

• Integrated Memory: Features $1K\times 8$ of on-chip EPROM and $64\times 8$ of internal RAM.
• High Efficiency: Over 96 instructions; 90% are single-byte, ensuring optimized program memory usage.
• Versatile I/O: Provides 27 dedicated I/O lines for system interfacing.
• On-Chip Resources: Includes an 8-bit interval timer/event counter and an on-board oscillator/clock circuit.
• Expandable: Fully compatible with MCS-80/MCS-85 peripherals for systems requiring additional memory or I/O capability.
• Dual Interrupts: Supports two single-level interrupts for real-time task management.
