FEATURES

2.1 Principal features s 2 kB/4 kB/8 kB Flash code memory with 1 kB erasable sectors, 64-byte erasable page size, and single byte erase. s 256-byte RAM data memory. s Two 16-bit counter/timers. Each timer may be conﬁgured to toggle a port output upon timer overﬂow or to become a PWM output. s Real-Time clock that can also be used as a system timer. s Two analog comparators with selectable inputs and reference source. s Enhanced UART with fractional baud rate generator, break detect, framing error detection, automatic address detection and versatile interrupt capabilities. s 400 kHz byte-wide I2C-bus communication port. s 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. s 2.4 V to 3.6 V VDD operating range.
