From the shop's description

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 1 K × 8 of on-chip EPROM and 64 × 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.
