Table 9. DC Characteristics

Note: 1. Valid for Ambient Operating Temperature: TA = –40 to 85°C; VCC = 4.5 to 5.5V or 2.7 to 3.6V (except where noted).

2. Applies to all input pins except RST, which is pulled internally to VCCI.

3. Measured without RAM connected.

4. ICCO1 is the maximum average load current the device can supply to external memory.

5. Voltages are referenced to Ground.

6. Measured with load shown in Figure 12., page 15.

7. ICCO2 is the maximum average load current that the device can supply to memory in the battery backup mode.
