Low power Real-Time Clock (RTC) with independent power and dedicated 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 nine edge or level sensitive external interrupt pins available.
60 MHz maximum CPU clock available from programmable on-chip PLL with settling
time of 100 µs.
On-chip integrated oscillator operates with an external crystal in range from 1 MHz to
30 MHz and with an external oscillator up to 50 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:
◆
CPU operating voltage range of 3.0 V to 3.6 V (3.3 V ± 10 %) with 5 V tolerant I/O
pads.
