Description
The AT89LV55 is a low-voltage, low-power CMOS 8-bit microcomputer with 20K
bytes of Flash programmable and erasable read only memory. The device is manu-
factured using Atmel’s high density nonvolatile memory technology and is compatible
with the industry standard 80C51 instruction set and pinout. The on-chip Flash allows
the program memory to be reprogrammed. By combining a versatile 8-bit CPU with
Flash on a monolithic chip, the Atmel AT89LV55 is a powerful microcomputer which
provides a highly flexible and cost effective solution to many embedded control appli-
cations.
