●   - Up to 25 MIPS throughput with 25 MHz clock

●   - Expanded interrupt handler Memory

●   - 768 bytes internal data RAM (256 + 512)

●   - 8 kB (‘F330/1), 4 kB (‘F332/3), or 2 kB (‘F334/5) Flash; In-system programmable in 512-byte Sectors—512 bytes are reserved in the 8 kB devices

●Digital Peripherals

●   - 17 Port I/O; All 5 V tolerant with high sink current

●   - Hardware enhanced UART, SMBus™, and enhanced SPI™ serial ports

●   - Four general purpose 16-bit counter/timers

●   - 16-Bit programmable counter array (PCA) with three capture/compare modules

●   - Real time clock mode using PCA or timer and external clock source

●Clock Sources

●   - Two internal oscillators:

●      • 24.5 MHz with ±2% accuracy supports crystal-less UART operation

●      • 80/40/20/10 kHz low frequency, low power

●   - External oscillator: Crystal, RC, C, or clock (1 or 2 pin modes)

●   - Can switch between clock sources on-the-fly; useful in power saving modes
