Atmel TS80C51RD2
TS8xC51Rx2 is a high performance CMOS ROM, OTP, EPROM and ROMless versions of the 80C51 CMOS single chip 8-bit microcontroller. The TS8xC51Rx2 retains all features of the 80C51 with extended ROM/EPROM capacity (16/32/64 Kbytes), 256 bytes of internal RAM, a 7-source , 4-level interrupt system, an on-chip oscilator and three timer/counters. The fully static design of the TS80C51Rx2 allows to reduce system power consumption by bringing the clock frequency down to any value, even DC, without loss of data.
