Description  
The AT87F51RC is a low-power, high-performance CMOS 8-bit microcomputer with  
32K bytes of QuickFlash one-time programmable (OTP) read only memory and 512  
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
