Description
The AT89LV52 is a low-voltage, high-performance CMOS 8-bit microcomputer with
8K bytes of Flash programmable and erasable read only memory. The device is man-
ufactured using Atmel’s high density nonvolatile memory technology and is compati-
ble with the industry standard 80C51 and 80C52 instruction set and pinout. The on-
chip Flash allows the program memory to be reprogrammed in-system or by a con-
ventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with
Flash on a monolithic chip, the Atmel AT89LV52 is a powerful microcomputer which
provides a highly flexible and cost effective solution to many embedded control appli-
cations. The AT89LV52 operates at 2.7 volts up to 6.0 volts.
