Real-Time Clock
— Alarm clock can turn the system on.
— Uses the existing 24-MHz XTAL for low cost or optional low power crystal (32.768 kHz
or 32.0 kHz), customer-selectable via OTP.
Customer-Programmable One-Time-Programmable (OTP) ROM via Integrated eFuse Block
— Resistor-less boot mode selection
— 128-bit boot mode crypto key
— Boot mode specification of NAND characteristics for device that the customer is
soldering to the board. This means no more costly delays waiting for new device support in t
he boot ROM.
— Fully software-programmable and accessible
Flexible I/O Pins
— All digital pins have drive-strength controls
— Most non-EMI digital pins have general-purpose input/output (GPIO) mode.
For comprehensive information on the microcontroller visit the Freescale’s web page for a
