Atmel AT89C51RC
The AT89C51RC is a low-power, high-performance CMOS 8-bit microcontroller with 32K bytes of Flash programmable read-only memory and 512 bytes of RAM. The device 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 the program memory to be user programmed by a conventional nonvolatile memory programmer.| Part No. | AT89C51RC |

DESCRIPTION
A total of 512 bytes of internal RAM are available in the AT89C51RC. 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 is a powerful microcomputer which provides a highly-flexible and cost-effective solution to many embedded control applications.
