TS80C31X2-VCAR

The TS80C31X2-VCAR is designed as one kind of high performance CMOS and ROMless versions of the 80C51 CMOS single chip 8-bit microcontroller. This device has 2 software-selectable modes of reduced activity for further reduction in power consumption, and in the power-down mode the RAM of it is saved and all other functions are inoperative.

Features of the TS80C31X2-VCAR are:(1)Asynchronous port reset;(2)Dual Data Pointer;(3)8031 pin and instruction compatible;(4)Four 8-bit I/O ports;(5)Two 16-bit timer/counters;(6)Interrupt Structure with 5 Interrupt sources and 4 priority level interrupt system;(7)Full duplex Enhanced UART;(8)Once mode (On-chip Emulation);(9)Power supply: 4.5-5.5 V, 2.7-5.5 V;(10)Temperature ranges: Commercial (0 to 70oC) and Industrial (-40 to 85 );(11)Packages: PDIL40, PLCC44, VQFP44 1.4, PQFP F1 (13.9 footprint).

The absolute maximum ratings of the TS80C31X2-VCAR can be summarized as:(1)Ambiant Temperature Under Bias (commercial): 0°C to 70°C;(2)Ambiant Temperature Under Bias (industrial): -40°C to 85°C;(3)Storage Temperature: -65°C to +150°C;(4)Voltage on Vcc to Vss: -0.5 V to +7 V;(5)Voltage on Vpp to Vss: -0.5 V to + 13 V;(6)Voltage on Any Pin to Vss: -0.5 V to Vcc+0.5 V;(7)Power Dissipation: 1 W.

The electrical characteristics of this TS80C31X2-VCAR can be summarized as:(1)Input Low Voltage: -0.5 to 0.2Vcc-0.1 V;(2)Input High Voltage except XTAL1, RST: 0.2Vcc+0.9 to Vcc+0.5 V;(3)Input High Voltage, XTAL1, RST: 0.7Vcc to Vcc+0.5 V;(4)RST Pulldown Resistor: 50 to 200 k;(5)Logical 0 Input Current ports 1, 2 and 3: -50 uA;(6)Input Leakage Current: ±10 uA;(7)Capacitance of I/O Buffer: 10 pF;(8)Power Down Current: 20 to 50 uA.
