●Temperature Range: –40 to +85 °C
●High Speed 8051 µC Core
● - Pipelined instruction architecture; executes 70% of instructions in 1 or 2 system clocks
● - 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

●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
