Product Overview

The AT32UC3L0256-AUT is a 32-bit high-performance AVR® UC3 RISC Microcontroller is designed for cost-sensitive embedded applications that require low power consumption, high code density and high performance. The microcontroller's memory protection unit (MPU) and fast, flexible interrupt controller support the latest real-time operating systems. The secure access unit (SAU) with MPU provide enhanced security and integrity. A rich set of DSP instructions delivers higher computational capability. The microcontroller embeds state-of-the-art picoPower® technology for ultra-low power consumption. A combination of power control techniques brings active current consumption down to 165µA/MHz and leakage down to 9nA while still retaining a bank of backup registers. The device offers a wide range of trade-offs between functionality and power consumption to reach the lowest possible power usage for the application's required feature set.
  • Compact single-cycle RISC instruction set including DSP instruction set
  • picoPower® technology for ultra-low power consumption
  • Multi-hierarchy bus system - High-performance data transfers on separate buses
  • Internal high-speed flash - Single-cycle access up to 25MHz
  • 32kB internal high-speed SRAM, single-cycle access at full speed
  • Interrupt controller (INTC) - Auto vectored low-latency interrupt service with programmable priority
  • External Interrupt Controller (EIC)
  • Peripheral event system for direct peripheral to peripheral communication
  • Windowed Watchdog Timer (WDT)
  • Asynchronous timer (AST) with real-time clock capability
  • Frequency meter (FREQM) for accurate measuring of clock frequency
  • Six 16bit timer/counter (TC) channels
  • PWM channels on all I/O pins (PWMA)
  • Four universal synchronous/asynchronous receiver/transmitters (USART)
  • Serial peripheral interface (SPI) with chip select signals
  • Two-wire interfaces (TWI), 400kBps I²C-compatible
  • One 8-channel analogue-to-digital converter (ADC) with up to 12-bit resolution
  • Eight analogue comparators (AC) with optional window detection
  • Capacitive touch (CAT) module
  • QTouch library support - Capacitive touch buttons, sliders and wheels
