IC MCU 8Bit 64KB OTP 64LQFP
Description
Atmel Wireless & Microcontrollers TS80C51Rx2 is high performance CMOS ROM, OTP, EPROM and ROMless versions of the 80C51 CMOS single chip 8-bit microcontroller.
The TS80C51Rx2 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.
In addition, the TS80C51Rx2 has a Programmable Counter Array, an XRAM of 256 or 768 bytes, a Hardware Watchdog Timer, a more versatile serial channel that facilitates multiprocessor communication EUART and a X2 speed improvement mechanism.
