D8751H – 8 Bit Control Oriented Microcontroller CDIP40
The D8751H – 8 Bit Control Oriented Microcontroller CDIP40 is a classic microcontroller from Intel’s MCS‑51 family, optimized for control‑centric embedded systems requiring reliable and efficient processing. Built around an 8‑bit CPU core, the D8751H integrates core functions necessary for control tasks, combining computational performance with ease of interfacing and broad support for control applications. The device includes an on‑chip memory scheme that facilitates program storage and execution while offering compatibility with external memory devices for expanded applications. The architecture is based on the standard Intel 8051 instruction set, enabling effective byte processing, numerical operations and fast addressing modes for internal RAM access, which together allow developers to implement responsive control logic in hardware‑constrained systems.
Features:
- 8‑bit MCS‑51 compatible CPU optimized for control‑oriented applications.
- 4K×8 on‑chip EPROM program memory with ultraviolet erasability and reprogrammability.
- 128×8 internal RAM including bit‑addressable area for efficient Boolean processing.
- Four 8‑bit I/O ports providing up to 32 programmable digital lines.
- Two 16‑bit timer/event counters for timing, counting, and pulse‑width measurement.
- Full‑duplex serial port supporting programmable communication modes.
- Two‑level interrupt priority structure with multiple interrupt sources.
- Supports up to 64K external program memory and 64K external data memory.
