Overview
The AVR32DD20T-I/REB is an 8-bit microcontroller from the AVR DD family, manufactured by Microchip Technology. It features a 24 MHz CPU speed, 32 KB of Flash memory, and 4 KB of SRAM. The device includes a 12-bit ADC with 13 channels and a 10-bit DAC. It operates within a supply voltage range of 1.8 V to 5.5 V and supports industrial temperatures from -40°C to +85°C. Packaged in a 20-VQFN (3x3) format, it offers interfaces including I2C, SPI, USART, IrDA, LINbus, and RS-485.
Feature Summary
- Features Multi-Voltage I/O (MVIO) on PORT C for flexible voltage level interfacing.
- Includes an Event System for CPU-independent inter-peripheral signaling.
- Supports automated cyclic redundancy check (CRC) scanning for Flash memory integrity.
Applications
- Smart metering and utility monitoring systems
- Industrial control and automation devices
- Wearable electronics and health monitoring prototypes
Procurement Notes
Verify that the ordering suffix 'I' corresponds to the required industrial temperature range (-40°C to +85°C). Confirm the package style matches the 20-VQFN specification. Ensure the tape and reel carrier type aligns with automated assembly requirements. Cross-reference the datasheet DS40002315 for complete electrical characteristics.
Selection Notes
Select this component when a balance of moderate pin count and advanced analog peripherals is needed. It provides vertical migration compatibility within the AVR DD family without code modification. Consider its low-power architecture and integrated event system for applications requiring efficient peripheral-to-peripheral communication.
Part Context
This part belongs to the AVR DD family, which utilizes the latest AVR CPU technology with a hardware multiplier. The family emphasizes flexibility through multi-voltage I/O and intelligent analog features. Devices in this series support unified program and debug interface (UPDI) programming via a single pin.
