ATMEL AT89C51RC handbook

Update: 28 September, 2023

The AT89C51RC is a low-power, high-performance CMOS 8-bit microcontroller with 32K bytes of reprogrammable flash memory and 512 bytes of RAM. It is manufactured using Atmel's high-density nonvolatile memory technology and is compatible with the industry-standard 80C51 and 80C52 instruction set and pinout. The on-chip flash allows user programming of the program memory using a conventional nonvolatile memory programmer. The AT89C51RC has 512 bytes of internal RAM available. The 256-byte expanded internal RAM is accessed via MOVX instructions after clearing bit 1 in the SFR located at address 8EH. The other 256-byte RAM segment is accessed the same way as the Atmel AT89-series and other 8052-compatible products. By combining a versatile 8-bit CPU with flash on a monolithic chip, the Atmel AT89C51RC provides a highly flexible and cost-effective solution.
