M48T212Y, M48T212V
Table 14. DC Characteristics
Note: 1. Valid for Ambient Operating Temperature: TA = 0 to 70°C or –40 to 85°C; VCC = 4.5 to 5.5V or 3.0 to 3.6V (except where noted).
2. RSTIN1 and RSTIN2 internally pulled-up to VCC through 100K resistor. WDI internally pulled-down to VSS through 100K resistor.
3. Outputs deselected.
4. IBAT (OSC ON) = Industrial Temperature Range - Grade 6 device.
5. For IRQ/FT & RST pins (Open Drain).
6. Conditioned outputs (E1CON - E2CON) can only sustain CMOS leakage currents in the battery back-up mode. Higher leakage cur-
rents will reduce battery life.
7. External SRAM must match TIMEKEEPER SUPERVISOR chip VCC specification.
