smsc emc1033 product preview revision 1.0 (04-15-05) data brief product features emc1033 1c triple smbus sensor with resistance error correction general description the emc1033 is an smbus temperature sensor that monitors up to three temperature zones and can generate two system in terrupts. with 1 c measurement accuracy, the emc1033 provides a low-cost solution for critical temperature monito ring applications. features include automatic resistan ce error correction and programmable ideality factor configuration eliminating both major sources of tem perature measurement error. 1 the emc1033 generates two separate interrupts with programmable thermal trip points. the therm output operates as a thermostat with programmable threshold and hysteresis. the alert output can be configured as a maskable smbus alert with programmable window comparator limits, or as a second therm output. both interrupts are maintained in an 8-pin package while a third temperature zone is added with the anti-parallel diode technique. this allows the emc1033 to be pin compatible with the adt7461, adm1032, lm99, and the max6649 with the advantage of a third temperature zone. features resistance e rror correction ideality factor configuration select 1 of 4 smbus addresses with external resistor remote thermal zones ? 1.0 c accuracy (40 c to 80 c) ? 0.125 c resolution internal thermal zone ? 3.0 c accuracy (0 c to 85 c) maskable interrupt using alert one-shot command during standby programmable temperature conversion rate extended temperature (-64 c to 191 c) available over-limit filtering wi th consecutive counter small 8-lead soic or tssop package applications desktop and notebook computers thermostats smart batteries industrial/automotive simplified block diagram 1.patents pending. emc1033 internal temp diode switching current smclk internal temp register digital mux digital mux limit comparator high limit registers therm hysterisis register low limit registers therm limit register address pointer register conversion rate register interrupt masking status register configuration register smbus interface remote temp register 1 remote temp register 2 alert smdata 11-bit delta-sigma adc analog mux dp1 dn2 dn1 dp2 therm
