MCU Frequency
12MHz (min) for USB;
8MHz (min) for I
Active Current, Typical
(25°C operation; 80% Flash and
15% SRAM accesses, 45 PLD
product terms used; PLD Turbo
mode Off)
Idle Current, Typical
(CPU halted but some peripherals
active; 25°C operation; 45 PLD
product terms used; PLD Turbo
mode Off)
Standby Current, Typical
(Power-down Mode, requires reset
to exit mode; without Low-Voltage
Detect (LVD) Supervisor)
SRAM Backup Current, Typical
(If external battery is attached.)
I/O Sink/Source Current

PLD Macrocells
(For registered or combinatorial
logic)
PLD Inputs
(Inputs from pins, macrocell
feedback, or MCU addresses)
PLD Outputs
(Output to pins or internal
feedback)
PLD Propagation Delay, Typical
