P8050AH Microcontroller 8-Bit MROM 8048 CPU 11MHz NMOS PDIP40 (Wide)
The P8050AH is an 8-bit microcontroller from Intel’s MCS-48 family, built on high-performance HMOS II NMOS technology. It integrates a self-sufficient 8048 CPU, 4KB of mask ROM for program storage, and 256 bytes of RAM for data handling. Designed for embedded control, it consolidates computing, timing, and I/O management into a single silicon chip.
Optimized for real-time processing, the device executes instructions in 1 or 2 cycles, achieving a rapid 1.36 µs cycle time at 11MHz. Its 96-instruction set emphasizes single-byte operations (90%), enabling compact code and efficient arithmetic/logic handling. The on-chip oscillator, timer/counter, and 27 I/O lines support autonomous operation while minimizing external components.
The P8050AH simplifies embedded designs with direct support for memory/I/O expansion via MCS-80/85 peripherals. It includes two interrupt levels and standby mode for power-sensitive applications. As a monolithic controller, it eliminates external memory needs for small-to-mid systems, balancing processing agility with hardware frugality.
