RAM (Wiper) Value Value Range N 0h — 1FFh hex 8-bit device 0h — 1FFh hex 7-bit device EEPROM Endurance Endurance — 1M — Cycles EEPROM Range N 0h — 1FFh hex Initial Factory Setting N 80h hex 8-bit WiperLock Technology = Off 40h hex 7-bit WiperLock Technology = Off EEPROM Pro- gramming Write Cycle Time tWC —5 10 ms Power Requirements Power Supply Sensitivity (MCP41X2 and MCP42X2 only) PSS — 0.0015 0.0035 %/% 8-bit VDD = 2.7V to 5.5V, VA = 2.7V, Code = 80h — 0.0015 0.0035 %/% 7-bit VDD = 2.7V to 5.5V, VA = 2.7V, Code = 40h AC/DC CHARACTERISTICS (CONTINUED) DC Characteristics Standard Operating Conditions (unless otherwise specified) Operating Temperature –40°C ≤ TA ≤ +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 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 over voltage and temperature. 8: The MCP4XX1 is externally connected to match the configurations of the MCP41X2 and MCP42X2, and then tested. 9: POR/BOR is not rate dependent. 10: Supply current is independent of current through the resistor network |
