n 2 kB/4 kB/8 kB Flash code memory with 1 kB erasable sectors, 64-byte erasable
page size, and single byte erase.
n 256-byte RAM data memory.
n Two 16-bit counter/timers. Each timer may be configured to toggle a port output
upon timer overflow or to become a PWM output.
n Real-Time clock that can also be used as a system timer.
n Two analog comparators with selectable inputs and reference source.
n Enhanced UART with fractional baud rate generator, break detect, framing error
detection, automatic address detection and versatile interrupt capabilities.
n 400 kHz byte-wide I
2
C-bus communication port.
n Configurable on-chip oscillator with frequency range and RC oscillator options
(selected by user programmed Flash configuration bits). The RC oscillator option
allows operation without external oscillator components. Oscillator options
support frequencies from 20 kHz to the maximum operating frequency of 12 MHz.
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 15 I/O pins minimum. Up to 18 I/O pins while using on-chip oscillator a
