User Peripherals
AT91M5880A
WD: Watchdog
SF: Special Function
USART: Universal Synchronous Asynchronous Receiver Transmitter
TC: Timer Counter
SPI: Serial Peripheral Interface
ADC: Analog-to-digital Converter
PIO Controllers called PIOA and PIOB. The PIO controller enables the generation of an interrupt
on input change and insertion of a simple input glitch filter on any of the PIO pins.
The Watchdog is built around a 16-bit counter, and is used to prevent system lock-up if the soft-
ware becomes trapped in a deadlock. It can generate an internal reset or interrupt, or assert an
active level on the dedicated pin NWDOVF. All programming registers are password-protected
to prevent unintentional programming.
The AT91M55800A provides registers which implement the following special functions.
The AT91M55800A provides three identical, full-duplex, universal synchronous/asynchronous
receiver/transmitters.
Each USART has its own baud rate generator, and two dedicated Peripheral Data Controller
channels. The data format includes a start bit, up to 8 data bits, an optional programmable parity
bit and up to 2 stop bits.
The USART also features a Receiver Timeout register, facilitating variable-length frame support
when it is working with the PDC, and a Time-guard register, used when interfacing with slow
remote equipment.
The AT91M55800A features two Timer Counter blocks that include three identical 16-bit timer
counter channels. Each channel can be independently programmed to perform a wide range of
functions including frequency measurement, event counting, interval measurement, pulse gen-
eration, delay timing and pulse-width modulation.
The Timer Counters can be used in Capture or Waveform mode, and all three counter channels
can be started simultaneously and chained together.
The SPI provides communication with external devices in master or slave mode. It has four
external chip selects that can be connected to up to 15 devices. The data length is programma-
ble, from 8- to 16-bit.
The two identical 4-channel 10-bit analog-to-digital converters (ADC) are based on a Successive
Approximation Register (SAR) approach.
Each ADC has 4 analog input pins, AD0 to AD3 and AD4 to AD7, digital trigger input pins
AD0TRIG and AD1TRIG, and provides an interrupt signal to the AIC. Both ADCs share the ana-
log power supply pins VDDA and GNDA, and the input reference voltage pin ADVREF.
