Low power Real-Time Clock (RTC) with independent power and 32 kHz clock input
Multiple serial interfaces including two UARTs (16C550), two Fast I
SPI and SSP with buffering and variable data length capabilities
Vectored Interrupt Controller (VIC) with configurable priorities and vector addresses
Up to 45 of 5 V tolerant fast general purpose I/O pins in a tiny LQFP64 package
Up to 21 external interrupt pins available
60 MHz maximum CPU clock available from programmable on-chip PLL with settling
time of 100 s
On-chip integrated oscillator operates with an external crystal from 1 MHz to 25 MHz
Power saving modes include Idle and Power-down
Individual enable/disable of peripheral functions as well as peripheral clock scaling for
additional power optimization
Processor wake-up from Power-down mode via external interrupt or BOD
Single power supply chip with POR and BOD circuits:
While the USB DMA is the primary user of the additional 8 kB RAM, this RAM is also accessible at any time
by the CPU as a general purpose RAM for data and code storage.
