TS80C52X2 is high performance CMOS ROM, OTP, EPROM and ROMless versions of the 80C51 CMOS single chip 8-bit microcontroller. | TS80C32X2 TS87C52X2 TS80C52X2 imEL WIRELESS pC 8-bit Microcontroller 8 Kbytes ROM OTP ROMless 1. Description TS80C52X2 is high performance CMOS ROM OTP EPROM and ROMless versions of the 80C51 CMOS single chip 8-bit microcontroller. The TS80C52X2 retains all features of the 80C51 with extended ROM EPROM capacity 8 Kbytes 256 bytes of internal RAM a 6-source 4-level interrupt system an on-chip oscilator and three timer counters. In addition the TS80C52X2 has a dual data pointer a more versatile serial channel that facilitates multiprocessor communication EUART and a X2 speed improvement mechanism. 2. Features 80C52 Compatible 8051 pin and instruction compatible Four 8-bit I O ports Three 16-bit timer counters 256 bytes scratchpad RAM High-Speed Architecture 40 MHz @ 5V 30MHz @ 3V X2 Speed Improvement capability 6 clocks machine cycle 30 MHz @ 5V 20 MHz @ 3V Equivalent to 60 MHz @ 5V 40 MHz @ 3V Dual Data Pointer On-chip ROM EPROM 8Kbytes Programmable Clock Out and Up Down Timer Counter 2 Asynchronous port reset The fully static design of the TS80C52X2 allows to reduce system power consumption by bringing the clock frequency down to any value even DC without loss of data. The TS80C52X2 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. Interrupt Structure with 6 Interrupt sources 4 level priority interrupt system Full duplex Enhanced UART Framing error detection Automatic address recognition Low EMI inhibit ALE Power Control modes Idle mode Power-down mode Power-off Flag Once mode On-chip Emulation Power supply Temperature ranges Commercial 0 to 70oC and Industrial -40 to 85oC Packages PDIL40 PLCC44 VQFP44 PQFP F1 footprint CQPJ44 window CDIL40 window - 16 November 2000 1 TS80C32X2 TS87C52X2 .
