27 / 58 page  2003 Microchip Technology Inc. Preliminary DS21790A-page 27 MCP2140 4.1 DC Characteristics DC Specifications Electrical Characteristics: Standard Operating Conditions (unless otherwise specified) Operating Temperature: -40 °C ≤ TA ≤ +85°C (industrial) Param. No. Sym Characteristic Min Typ(1) Max Units Conditions D001 VDD Supply Voltage 3.0 — 5.5 V See Figure 4-1 D002 VDR RAM Data Retention Voltage (2) 2.0 — — V Device Oscillator/Clock stopped D003 VPOR VDD Start Voltage to ensure Power-on Reset — VSS — V D004 SVDD VDD Rise Rate to ensure Power-on Reset 0.05 — — V/ms D010 D010A IDD Supply Current (3, 4) — — — 25 2.2 60 mA µA VDD = 3.0V, PHACT = H VDD = 3.0V, PHACT = L Note 1: Data in the Typical (“Typ”) column is based on characterization results at 25 °C. This data is for design guidance only and is not tested. 2: This is the limit to which VDD can be lowered without losing RAM data. 3: When the device is in IR communication (PHACT pin is high), supply current is mainly a function of the operating voltage and frequency. Pin loading, pin rate and temperature have an impact on the current con- sumption.The test conditions for all IDD measurements are made when device is: OSC1 = external square wave, from rail-to-rail; all input pins pulled to VSS, RXIR = VDD, RESET = VDD; 4: When the device is in low power mode (PHACT pin is low), current is measured with all input pins tied to VDD or VSS and the output pins driving a high or low level into infinite impedance. |
