8 kB byte-erasable Flash code memory organized into 1 kB sectors and 64-byte
pages. Single-byte erasing allows any byte(s) to be used as non-volatile data storage.
n 256-byte RAM data memory, 512-byte auxiliary on-chip RAM.
n 512-byte customer data EEPROM on chip allows serialization of devices, storage of
set-up parameters, etc.
n Two *og comparators with selectable inputs and reference source.
n Two 16-bit counter/timers (each may be configured to toggle a port output upon timer
overflow or to become a PWM output) and a 23-bit system timer that can also be used
as a Real-Time Clock (RTC).
n Enhanced UART with fractional baudrate generator, break detect, framing error
detection, and automatic address detection; 400 kHz byte-wide I2C communication
port and SPI communication port.
n Capture/Compare Unit (CCU) provides PWM, input capture, and output compare
functions.
n High-accuracy internal RC oscillator option allows operation without external oscillator
components.The RC oscillator option is selectable and fine tunable.
n 2.4 V to 3.6 V VDD operating range. I/O pins are 5 V tolerant (may be pulled up or
driven to 5.5 V).
n 28-pin TSSOP, PLCC, and HVQFN packages with 23 I/O pins minimum and up to 26
I/O pins while using on-chip oscillator and reset options.
