1. Valid for ambient operating temperature: TA = –40 to 85°C; VCC = 2.7 to 3.6V or 4.5 to 5.5V(except where noted).
2. Measured with VOUT and ECON open.
3. RSTIN internally pulled-up to VCC through 100kΩ resistor.
4. Outputs deselected.
5. External SRAM must match SUPERVISOR chip VCC specification (3V or 5V).
6. For rechargeable back-up, VBAT (max) may be considered VCC – 0.5V.
7. For PFO pin (CMOS).
8. Chip enable output (ECON) can only sustain CMOS leakage currents in the battery back-up mode. Higher leakage currents
will reduce battery life.
9. For RST & BL pins (open drain).
