Overview
The AVR32DD32-E/PT is an 8-bit microcontroller from the AVR DD Family, utilizing the AVR CPU with a hardware multiplier. It features 64 KB of Flash memory, 8 KB of SRAM, and 256 bytes of EEPROM. The device operates at clock speeds up to 24 MHz and supports a supply voltage range of 1.8 V to 5.5 V. It includes a 12-bit differential ADC, a 10-bit DAC, two USARTs, SPI, TWI/I2C, and an Event System. The component is housed in a TQFP-32 package and is rated for extended industrial temperature operation from -40°C to +125°C.
Feature Summary
- AVR CPU with hardware multiplier running at up to 24 MHz
- Multi-Voltage I/O (MVIO) on Port C with selectable input thresholds
- Configurable Custom Logic (CCL) with four programmable Look-up Tables
- Automated CRC Flash memory scan for data integrity
Applications
- Industrial control systems requiring extended temperature tolerance
- Power management applications using optimized Timer/Counter type D
- Embedded devices needing multi-voltage interface compatibility
Procurement Notes
Verify the ordering suffix 'E' confirms the extended temperature range (-40°C to +125°C) and 'PT' indicates the TQFP-32 package. Ensure the specific part number matches the required memory size and peripheral configuration as defined in the official datasheet DS40002315C before finalizing procurement.
Selection Notes
Select this model when extended temperature performance is required alongside high memory capacity within the AVR DD family. It offers vertical migration compatibility with other DD series devices without code modification. Consider the MVIO feature if interfacing with mixed-voltage peripherals is necessary.
Part Context
This component belongs to the AVR DD Family, which provides flexible low-power architecture with intelligent analog features. The family supports horizontal and vertical migration between pin counts and memory sizes while maintaining pin and feature compatibility across variants.
Replacement Considerations
AVR32DD32-I/PT: Identical specifications except for the Industrial temperature range (-40°C to +85°C).
