Table 6. Capacitance (1)
(TA =25 °C, f = 1 MHz)
Note: 1. Sampled only, not 100% tested.
2. Outputs deselected.
Table 7A. DC Characteristics for M48T212V
(TA = 0 to 70°C; VCC = 3V to 3.6V)
Note: 1. Outputs deselected.
2. RSTIN1 and RSTIN2 internally pulled-up to VCC through 100K resistor. WDI internally pulled-down to VSS through 100K resistor.
3. For IRQ/FT & RST pins (Open Drain).
4. Conditioned outputs (E1CON -E2CON) can only sustain CMOS leakage currents in the battery back-up mode. Higher leakage cur-
rents will reduce battery life.
5. External SRAM must match TIMEKEE PER Controller chip VCC specification.
