AC/DC CHARACTERISTICS DC Characteristics Standard Operating Conditions (unless otherwise specified) Operating Temperature –40°C ≤ T A ≤ +125°C (extended) All parameters apply across the specified operating ranges unless noted. VDD = +2.7V to 5.5V, 5 kΩ, 10 kΩ, 50 kΩ, 100 kΩ devices. Typical specifications represent values for VDD = 5.5V, TA = +25°C. Parameters Sym Min Typ Max Units Conditions Supply Voltage VDD 2.7 — 5.5 V 1.8 — 2.7 V Serial Interface only. HVC pin Voltage Range VHV VSS — 12.5V V VDD ≥ 4.5V The HVC pin will be at one of three input levels (VIL, VIH or VIHH). (Note 6) VSS —VDD + 8.0V VVDD < 4.5V VDD Start Voltage to ensure Wiper Reset VBOR — — 1.65 V RAM retention voltage (VRAM) < VBOR VDD Rise Rate to ensure Power-on Reset VDDRR (Note 9)V/ms Delay after device exits the reset state (VDD > VBOR) TBORD —10 20 µs Supply Current (Note 10) IDD — — 600 µA Serial Interface Active, HVC/A0 = VIH (or VIL) (Note 11) Write all 0’s to Volatile Wiper 0 VDD = 5.5V, FSCL = 3.4 MHz — — 250 µA Serial Interface Active, HVC/A0 = VIH (or VIL) (Note 11) Write all 0’s to Volatile Wiper 0 VDD = 5.5V, FSCL = 100 kHz — 2.5 5 µA Serial Interface Inactive, (Stop condition, SCL = SDA = VIH), Wiper = 0 VDD = 5.5V, HVC/A0 = VIH Note 1: Resistance is defined as the resistance between terminal A to terminal B. 2: INL and DNL are measured at VW with VA = VDD and VB = VSS. 3: MCP4XX1 only. 4: MCP4XX2 only, includes VWZSE and VWFSE. 5: Resistor terminals A, W and B’s polarity with respect to each other is not restricted. 6: This specification by design. 7: Non-linearity is affected by wiper resistance (RW), which changes significantly overvoltage and temperature. 8: The MCP4XX1 is externally connected to match the configurations of the MCP45X2 and MCP46X2, and then tested. 9: POR/BOR is not rate dependent. 10: Supply current is independent of current through the resistor network 11: When HVC/A0 = VIHH, the IDD current is less due to current into the HVC/A0 pin.
