This is a stress ratings only and functional operation of the device at those or any other conditions above those indicated in the operational listing of this specifications is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. ELECTRICAL CHARACTERISTICS Electrical Characteristics: Unless otherwise noted, VDD = 5V for L/M versions, VDD = 3.3V for T/S versions, VDD = 3V for R version, TA = -40°C to +125°C. Typical values are at TA = +25°C. Parameter Sym Min Typ(1) Max Units Test Conditions Operating Voltage Range V DD 1.0 — 5.5 V Supply Current IDD —7 15 µA VDD > VTRIP, for L/M/R/S/T, VDD = 5.5V —4.75 10 µA VDD > VTRIP, for R/S/T, VDD = 3.6V —10 15 µA VDD < VTRIP, for L/M/R/S/T Reset Trip Point Threshold (3) VTRIP 4.54 4.63 4.72 V TC127xAL: TA = +25°C 4.50 — 4.75 V TA = –40°C to +125°C 4.30 4.38 4.46 V TC127xAM: TA = +25°C 4.25 — 4.50 V TA = –40°C to +125°C 3.03 3.08 3.14 V TC127xAT: TA = +25°C 3.00 — 3.15 V TA = –40°C to +125°C 2.88 2.93 2.98 V TC127xAS: TA = +25°C 2.85 — 3.00 V TA = –40°C to +125°C 2.72 2.77 2.82 V TC127xA:(5) TA = +25°C 2.70 — 2.85 V TA = –40°C to +125°C 2.58 2.63 2.68 V TC127xAR: TA = +25°C 2.55 — 2.70 V TA = –40°C to +125°C Note 1: Data in the Typical (“Typ”) column is at 5V, +25 °C, unless otherwise stated. 2: RST output for TC1270A, and TC1270AN, RST output for TC1271A. 3: TC127XA refers to either the TC1270A, TC1270AN or TC1271A device. 4: Hysteresis is within the VTRIP(MIN) to VTRIP(MAX) window. 5: Custom ordered Voltage Trip Point. Minimum order volume requirement. 6: This specification allows this device to be used in PIC® microcontroller applications that require the In-Circuit Serial Programming™ (ICSP™) feature (see device-specific programming specifications for voltage requirements). The total time that the RST pin can be above the maximum device operational voltage (5.5V) is 100s. Current into the RST pin should be limited to 2 mA. It is recommended that the device operational temperature be maintained between 0°C to +70°C (+25°C preferred). For additional information, refer to Figure 2-41. |
