About this item

The P8049AH is an 8-bit microcontroller from Intel's MCS-48 family, designed for embedded control applications requiring efficient processing and compact integration. Operating at a clock speed of 11 MHz, it features a 12-bit address bus and an 8-bit data bus, enabling it to address up to 4 KB of memory. The microcontroller is equipped with 2 KB of masked ROM, providing a cost-effective solution for mass-produced devices. With 24 programmable I/O pins, the P8049AH offers versatile interfacing capabilities, suitable for controlling peripherals and handling user inputs. It includes two timers/counters and supports two external interrupt lines, enhancing its responsiveness in real-time applications. The microcontroller's architecture is based on NMOS technology, and it comes in a 40-pin Ceramic Dual In-line Package (CDIP), making it compatible with through-hole mounting in various electronic systems. The P8049AH was widely utilized in consumer electronics during the late 1970s and 1980s, including devices like the Magnavox Odyssey video game console and IBM PC keyboards. Its low cost, efficient instruction set, and mature development tools contributed to its popularity in high-volume applications. Although now discontinued, the P8049AH remains a significant part of microcontroller history.
