VSS ..... -0.3V to VDD +0.3V Storage temperature ..........................-65°C to +150°C Ambient temp. with power applied .....-55°C to +125°C Junction Temperature......................................... 150°C ESD protection on all pins: Human Body Model (HBM)..............................>4 kV Machine Model (MM) ......................................>200V † Notice: Stresses above those listed under "Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability. PIN FUNCTION TABLE Name Function SI/O Serial Data Pin SCK Serial Clock VSS Ground CS Chip Select (Active-Low) NC No Connection VDD Power Supply DC CHARACTERISTICS Electrical Specifications: Unless otherwise noted, all parameters apply at VDD = 2.7V to 5.5V and TA = -55°C to +125°C. Parameters Sym Min Typ Max Units Conditions Power Supply Operating Voltage Range VDD 2.7 — 5.5 V Note 1 Operating Current IDD — 250 400 µA Continuous Temperature Conversion Mode Power-On Reset Threshold VPOR 1.2 1.6 2.2 V V DD falling or rising edge Standby Supply Current IDD- STANDBY — 0.1 1.0 µA Shutdown Mode Temperature to Bits Converter Resolution — 13 — Bits ADC LSb = 0.0625°C/bit (Note 4) Temperature Conversion Time tCT — 300 400 ms Temperature Accuracy (Note 1) TERR -1.0 -2.0 -3.0 — — — +1.0 +2.0 +3.0 °C +25°C < TA < +65°C -40°C < TA < +85°C -55°C < TA < +125°C TC77-3.3MXX: VDD = 3.3V TC77-5.0MXX: VDD = 5.0V Note 1: The TC77-3.3MXX and TC77-5.0MXX will operate from a supply voltage of 2.7V to 5.5V. However, the tem- perature accuracy of the TC77-3.3MXX and TC77-5.0MXX is specified at the nominal operating voltages of 3.3V and 5.0V, respectively. As VDD varies from the nominal operating value, the accuracy may be degraded (Refer to Figures 2-6 and 2-7). 2: All time measurements are measured with respect to the 50% point of the signal. 3: Load Capacitance, CL = 80 pF, is used for AC timing measurements of output signals. 4: Resolution = Temperature Range/No. of Bits = (+255°C – -256°C) / (213) Resolution = 512/8192 = 0.0625°C/Bit |
