Timer/Counters
AT89LP microcontrollers have two or more 16-bit timers for use as system timers or event
counters. Timer 0 and Timer 1 can independently generate 8-bit pulse width modulation
waveforms. Timer 2 on the AT89LP828 and AT89LP6440 is paired with a 4 channel
Compare/Capture Array (CCA) to capture events and perform measurements on multiple
channels or to generate multi-phasic PWM waveforms for advanced motor control.
Serial Communication
AT89LP microcontrollers may include a full Serial Peripheral Interface (SPI) bus for high-
speed serial communication with both master and slave modes; an enhanced UART with
automatic address recognition and framing error detection; and an I2C-comptaible master-
slave Two-Wire Interface (TWI).
Analog Peripherals
AT89LP microcontrollers may include one or more analog comparators with selectable
interrupt modes and a tunable digital debouncer. Some devices also include an integrated
10-bit analog-to-digital converter (ADC) with multiple input channels and single-ended or
fully differential operation, plus a digital-to-analog (DAC) operating mode.
Configurable I/O
Each pin of an AT89LP microcontroller is independently configurable in one of four modes:
input-only (high impedance), open-drain, push-pull CMOS output, or Quasi-bidirectional
(8051-style). These modes can allow on-chip pull-ups to be disabled to reduce power, the
use of Port 0 without external pull-ups or greater current sourcing capabilities. In addition,
all pins of Port 1 may be configured to generate an interrupt for a variety of edge or level
conditions.
Supervisory Functions
AT89LP microcontrollers integrate several supervisory functions on chip, including Power-
on Reset, Brown-out Detection, Software Reset, and a Watchdog Timer.
Clock Selection
The AT89LP devices can be clocked from several clock sources, including:
External clock source
On-chip crystal oscillator in high or low frequency mode
Internal RC oscillators with ±5% or better accuracy
