The Frequency Meter (FREQM) allows accurate measuring of a clock frequency by comparing it
to a known reference clock.
The Full-speed USB 2.0 device interface (USBC) supports several USB classes at the same
time, thanks to the rich end-point configuration.
The device includes six identical 16-bit Timer/Counter (TC) channels. Each channel can be inde-
pendently programmed to perform frequency measurement, event counting, interval
measurement, pulse generation, delay timing, and pulse width modulation.
The Pulse Width Modulation controller (PWMA) provides 12-bit PWM channels which can be
synchronized and controlled from a common timer. 36 PWM channels are available, enabling
applications that require multiple PWM outputs, such as LCD backlight control. The PWM chan-
nels can operate independently, with duty cycles set individually, or in interlinked mode, with
multiple channels changed at the same time.
The ATUC64/128/256L3/4U also features many communication interfaces, like USART, SPI,
and TWI, for communication intensive applications. The USART supports different communica-
tion modes, like SPI Mode and LIN Mode.
A general purpose 8-channel ADC is provided, as well as eight analog comparators (AC). The
ADC can operate in 10-bit mode at full speed or in enhanced mode at reduced speed, offering
up to 12-bit resolution. The ADC also provides an internal temperature sensor input channel.
The analog comparators can be paired to detect when the sensing voltage is within or outside
the defined reference window.
The Capacitive Touch (CAT) module senses touch on external capacitive touch sensors, using
the QTouch technology. Capacitive touch sensors use no external mechanical components,
unlike normal push buttons, and therefore demand less maintenance in the user application.
The CAT module allows up to 17 touch sensors, or up to 16 by 8 matrix sensors to be interfaced.
All touch sensors can be configured to operate autonomously without software interaction,
allowing wakeup from sleep modes when activated.
Atmel offers the QTouch library for embedding capacitive touch buttons, sliders, and wheels
functionality into AVR microcontrollers. The patented charge-transfer signal acquisition offers
robust sensing and includes fully debounced reporting of touch keys as well as Adjacent Key
Suppression® (AKS®) technology for unambiguous detection of key events. The easy-to-use
QTouch Suite toolchain allows you to explore, develop, and debug your own touch applications.
The Audio Bitstream DAC (ABDACB) converts a 16-bit sample value to a digital bitstream with
an average value proportional to the sample value. Two channels are supported, making the
ABDAC particularly suitable for stereo audio.
The Inter-IC Sound Controller (IISC) provides a 5-bit wide, bidirectional, synchronous, digital
audio link with external audio devices. The controller is compliant with the Inter-IC Sound (I2S)
bus specification.
The ATUC64/128/256L3/4U integrates a class 2+ Nexus 2.0 On-chip Debug (OCD) System,
with non-intrusive real-time trace and full-speed read/write memory access, in addition to basic
runtime control. The NanoTrace interface enables trace feature for aWire- or JTAG-based
debuggers. The single-pin aWire interface allows all features available through the JTAG inter-
face to be accessed through the RESET pin, allowing the JTAG pins to be used for GPIO or
peripherals.
