SUPPLY CURRENT CHARACTERISTICS (Cont’d)
12.4.3 On-Chip Peripherals
Measured on LQFP64 generic board T
A
= 25°C f
CPU
=4MHz.
Notes:
1. Data based on a differential I
DD
measurement between reset configuration (timer counter running at f
CPU
/4) and timer
counter stopped (only TIMD bit set). Data valid for one timer.
2. Data based on a differential I
DD
measurement between reset configuration (timer stopped) and timer counter enabled
(only TCE bit set).
3. Data based on a differential I
DD
measurement between reset configuration (SPI disabled) and a permanent SPI master
communication at maximum speed (data sent equal to 55h).This measurement includes the pad toggling consumption.
4. Data based on a differential I
DD
measurement between SCI low power state (SCID=1) and a permanent SCI data trans-
mit sequence.
5. Data based on a differential I
DD
measurement between reset configuration (I2C disabled) and a permanent I2C master
communication at 100kHz (data sent equal to 55h). This measurement include the pad toggling consumption (27kOhm
external pull-up on clock and data lines).
6. Data based on a differential I
DD
measurement between reset configuration and continuous A/D conversions.
