P8049AH Microcontroller IC DIP-40

The Intel P8049AH is a high-performance, single-component 8-bit microcontroller fabricated with HMOS II technology. It is a fully self-sufficient parallel computer integrated onto a single silicon chip, designed to serve as an efficient controller and arithmetic processor. Its core includes an 8-bit CPU, an on-board oscillator, and clock circuits, allowing it to form the heart of a compact control system with minimal external components. The architecture is optimized for control tasks with extensive bit-handling capabilities and support for both binary and BCD arithmetic.

This microcontroller contains its own program and data memory on-chip, featuring 2K x 8 bits of Mask ROM and 128 x 8 bits of RAM. This integrated memory allows the processor to execute its instruction set—which consists mostly of single-byte instructions for efficient memory use—directly from internal storage. The design includes an 8-bit timer/counter that can function as an interval timer or an event counter, adding to its capability for creating precise timing delays or counting external pulses without external hardware.

For systems requiring extra capability, the P8049AH is designed for easy expansion. It provides 27 I/O lines, organized into ports and a bidirectional bus, which can be used to interface with a wide range of peripherals. The memory and I/O can be expanded using standard MCS-80/MCS-85 peripherals. Control signals like ALE, PSEN, RD, and WR facilitate this expansion, allowing the microcontroller to manage external program memory, data memory, and additional I/O ports seamlessly.
