FEATURES

2.1 Principal features s 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 4-input 8-bit multiplexed A/D converter/single DAC output. 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 (factory calibrated to ±1 %) option allows operation without external oscillator components. Oscillator options support frequencies from 20 kHz to the maximum operating frequency of 18 MHz.
