The ATUC128D4-Z1UR is a 32-bit microcontroller from Microchip (formerly Atmel), based on the AVR core. It operates at up to 48 MHz and provides 128 KB of flash memory and 16 KB of SRAM. The device supports a supply voltage range of 1.65V to 3.6V and includes peripherals such as DMA, I2S, PWM, brown-out detection, and a watchdog timer. Packaged in a 48-VFQFN with exposed pad, it is designed for audio, industrial, and portable applications requiring efficient processing and low power consumption.
- Integrated I2S: Native audio interface simplifies connection to digital audio codecs, reducing external components.
- Low Voltage Operation: Supports down to 1.65V, ideal for single-cell battery applications.
- DMA Controller: Offloads data transfer tasks from the CPU, improving overall system efficiency.
- Compact Package: The 48-VFQFN with exposed pad offers excellent thermal performance in a small footprint.
- Rich Peripheral Set: Includes PWM, WDT, and brown-out detection for robust embedded designs.
Audio Processing Modules
The integrated I2S interface and DMA allow direct streaming of audio data to codecs. The 48 MHz AVR core can handle real-time audio effects and equalization.
Portable Medical Devices
Low voltage operation (1.65V) extends battery life in glucose meters or pulse oximeters. The 16 KB RAM buffers sensor data, while the WDT ensures safe operation.
Industrial Sensor Nodes
The 48-VFQFN package with exposed pad aids thermal dissipation in compact enclosures. DMA reduces CPU load when collecting data from multiple ADC channels.
Smart Home Controllers
With PWM and multiple timers, it can drive LED dimmers and motorized blinds. The brown-out detector prevents erratic behavior during power dips.
Consumer Electronics Remote Controls
Its low-power modes and fast wake-up make it suitable for battery-operated remotes. The 128 KB flash stores complex IR/RF protocol stacks.
Automotive Infotainment Accessories
Although not AEC-Q100, its I2S and DMA support audio routing in aftermarket head units. The -40°C to 85°C range covers cabin environments.
