Description  
The AT87LV52 is a low-voltage, high-performance CMOS 8-bit microcomputer with  
8K bytes of QuickFlash one-time programmable (OTP) read only memory. The device  
is manufactured using Atmel’s high-density nonvolatile memory technology and is  
compatible with the industry standard MCS-51instruction set and pinout. The on-  
chip QuickFlash allows the program memory to be user programmed by a conven-  
tional nonvolatile memory programmer. By combining a versatile 8-bit CPU with  
QuickFlash on a monolithic chip, the Atmel AT87LV52 is a powerful microcomputer  
which provides a highly flexible and cost effective solution to many embedded control  
AT87LV52  
applications.
