DS22242A-page 11 MCP433X/435X Weak Pull-up Current IPU — — 1.75 mA Internal VDD pull-up, VIHH pull-down, VDD = 5.5V, VCS = 12.5V —170 — µA CS pin, VDD = 5.5V, VCS = 3V CS Pull-up/ Pull-down Resistance RCS —16 — k VDD = 5.5V, VCS = 3V RESET Pull-up Resistance RRESET —16 — k VDD = 5.5V, VRESET = 0V Input Leakage Current IIL -1 — 1 µA VIN = VDD (all pins) and VIN = VSS (all pins except RESET) Pin Capacitance CIN, COUT —10 — pF fC = 20 MHz RAM (Wiper, TCON) Value Value Range N 0h — 1FFh hex 8-bit device 0h — 1FFh hex 7-bit device TCON POR/BOR Setting 1FF hex All terminals connected Wiper POR/BOR Setting N 080h hex 8-bit 040h hex 7-bit Power Requirements Power Supply Sensitivity (MCP43X1) 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 k, 10 k, 50 k, 100 k 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: MCP43X1 only. 4: MCP43X2 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 MCP43X1 is externally connected to match the configurations of the MCP43X2, and then tested. 9: POR/BOR is not rate dependent. 10: Supply current is independent of current through the resistor network. |
