TS87C51RD2 ATMEL Corporation, TS87C51RD2 Datasheet - Page 2

• Manufacturer Part Number: TS87C51RD2
• Description: (TS8xC51Rx2) High Performance 8-bit Microcontroller
• Manufacturer: ATMEL Corporation

tates multiprocessor communication (EUART) and an X2 speed improvement mechanism.
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.
The TS80C51Rx2 has 2 software-selectable modes of reduced activity for further reduction in power consumption. In the
idle mode the CPU is frozen while the timers, the serial port and the interrupt system are still operating. In the power-down
mode the RAM is saved and all other functions are inoperative.
