Product Summary

The AT89S52-24AU is a low-power, high-performance CMOS 8-bit microcontroller with 8Kbytes of in-system programmable Flash memory. The device is manufactured using high-density nonvolatile memory technology and is compatible with the industry-standard 80C51 instruction set and pinout. The on-chip Flash allows the programmemory to be reprogrammed in-system or by a conventional nonvolatile memory pro-grammer. By combining a versatile 8-bit CPU with in-system programmable Flash ona monolithic chip, the AT89S52-24AU is a powerful microcontroller which provides a highly-flexible and cost-effective solution to many embedded control applications.
