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 I2C-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 (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. 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 High drive current (20 mA) on eight I/O pins on the P89LPC9221 (P0.3 to P0.7,
P1.4, P1.6, P1.7).
