P87C055BBP, 8-Bit Microcontroller, SDIP-42

The P87C055BBP is a high-performance 8-bit microcontroller designed for TV and video applications. Based on the 80C51 architecture, it incorporates specialized functions including an On-Screen Display (OSD) controller, multiple Pulse Width Modulation (PWM) outputs, and various I/O interfaces. This device is an EPROM version of the 83C055, allowing for programmability and flexibility in development.

With 16KB of on-chip ROM (EPROM in the P87C055) and 256 bytes of RAM, this microcontroller efficiently handles embedded applications. It supports multiple digital video outputs, 6-bit and 14-bit PWM DACs, and an advanced video processing engine. The On-Screen Display (OSD) module enables text and graphical overlays, making it an ideal choice for television receivers, tuners, and multimedia systems.

The P87C055BBP operates at clock speeds of up to 12MHz and requires a single 5V power supply, simplifying power management. Its SDIP-42 package ensures easy integration into various electronic systems. Designed for low power consumption, it is well-suited for energy-efficient video processing and display applications.
