1 / 58 page  Rev. C - 15 January, 2001 1 TS80C54X2/C58X2 TS87C54X2/C58X2 8-bit CMOS Microcontroller 16/32 Kbytes ROM/OTP 1. Description TS80C54/58X2 is high performance CMOS ROM, OTP and EPROM versions of the 80C51 CMOS single chip 8-bit microcontroller. The TS80C54/58X2 retains all features of the Atmel Wireless & Microcontrollers 80C51 with extended ROM/EPROM capacity (16/32 Kbytes), 256 bytes of internal RAM, a 6-source , 4-level interrupt system, an on-chip oscilator and three timer/counters. In addition, the TS80C54/58X2 has a Hardware Watchdog Timer, a more versatile serial channel that facilitates multiprocessor communication (EUART) and a X2 speed improvement mechanism. The fully static design of the TS80C54/58X2 allows to reduce system power consumption by bringing the clock frequency down to any value, even DC, without loss of data. The TS80C54/58X2 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. 2.
