Description  
The AT87F55 is a low-power, 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 Atmels high-density nonvolatile memory  
technology and is compatible with the industry standard 80C51 and 80C52 instruction  
set and pinout. The on-chip QuickFlash allows the program memory to be user pro-
