Description  
The AT87LV55 is a low-voltage, high-performance CMOS 8-bit microcomputer with  
20K bytes of QuickFlash one-time programmable (OTP) read only memory and 256  
bytes of RAM. The device is manufactured using Atmel’s high-density nonvolatile  
memory technology and is compatible with the industry standard MCS-51 instruction  
set and pinout. The on-chip QuickFlash allows the program memory to be user pro-
