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-  
AT89LV55  
cations.
