Digital Inputs/Outputs (HVC/A0, A1, SDA, SCL, RESET) Schmitt Trigger High Input Threshold VIH 0.45 VDD — — V All Inputs except SDA and SCL 2.7V VDD 5.5V (Allows 2.7V Digital VDD with 5V Analog VDD) 0.5 VDD —— V 1.8V VDD 2.7V 0.7 VDD —VMAX V SDA and SCL 100 kHz 0.7 VDD —VMAX V400 kHz 0.7 VDD —VMAX V1.7 MHz 0.7 VDD —VMAX V3.4 Mhz Schmitt Trigger Low Input Threshold VIL — — 0.2VDD V All inputs except SDA and SCL -0.5 — 0.3VDD V SDA and SCL 100 kHz -0.5 — 0.3VDD V400 kHz -0.5 — 0.3VDD V1.7 MHz -0.5 — 0.3VDD V3.4 Mhz Hysteresis of Schmitt Trigger Inputs VHYS —0.1VDD — V All inputs except SDA and SCL N.A. — — V SDA and SCL 100 kHz VDD < 2.0V N.A. — — V VDD 2.0V 0.1 VDD —— V 400 kHz VDD < 2.0V 0.05 VDD —— V VDD 2.0V 0.1 VDD —— V 1.7 MHz 0.1 VDD —— V 3.4 Mhz High Voltage Input Entry Voltage VIHHEN 9.0 — 12.5 (Note 6) V Threshold for WiperLock Technology High Voltage Input Exit Voltage VIHHEX —— VDD + 0.8V (Note 6) V High Voltage Limit VMAX —— 12.5 (Note 6) V Pin can tolerate VMAX or less. Output Low Voltage (SDA) VOL VSS —0.2VDD VVDD < 2.0V, IOL = 1 mA, VSS —0.4 V VDD ≥2.0V, IOL = 3 mA 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: MCP44X1 only. 4: MCP44X2 only, includes VWZSE and VWFSE. 5: Polarity of resistor terminals A, W and B, 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 MCP44X1 is externally connected to match the configurations of the MCP44X2, 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. See IPU specification. |
