Notes: 1. Output buffer current is excluded.
2. ICC is the source current when no I/O current is flowing while the MCU is in reset state.
Test conditions: MCU: Reset
Pins: RESET at VCC (0.9VCC to VCC)
TEST at VCC (0.9VCC to VCC)
3. ISBY is the source current when no I/O current is flowing while the MCU timer is operating.
Test conditions: MCU: I/O reset
Serial interface stopped
Standby mode
Pins: RESET at GND (0 V to 0.3 V)
TEST at VCC (0.9VCC to VCC)
4. These are the source currents when no I/O current is flowing.
Test conditions: Pins: RESET at GND (0 V to 0.3 V)
TEST at VCC (0.9VCC to VCC)
D10* at VCC (0.9VCC to VCC)
Note: * Applies to HD4074459
5. RAM data retention is the voltage required for retaining RAM data.
