R65C02P2 Microprocessor ROCKWELL DIP-40 IC
The R65C02P2 is an 8-bit CMOS microprocessor from Rockwell, leveraging silicon gate technology to deliver enhanced performance and cost efficiency over its NMOS predecessors. It maintains full software compatibility with the iconic R6502 architecture, ensuring seamless integration into legacy systems while improving power efficiency and thermal management.
Designed for high-reliability applications, the R65C02P2 integrates an on-chip clock oscillator, eliminating the need for external timing components in standalone setups. Its 16-bit address bus supports 64KB of memory, and it features bidirectional data handling, true indexing, and programmable stack management for efficient data processing and real-time control.
Targeted at embedded and industrial systems, the R65C02P2 excels in deterministic environments requiring low power (4 mA/MHz) and robust interrupt handling (IRQ/NMI). Its DIP-40 packaging simplifies prototyping and integration, making it ideal for retro-computing, control systems, and educational hardware where simplicity and reliability are critical.
