AVR64DD32-E/PT

Overview

The AVR64DD32-E/PT is an 8-bit microcontroller from the AVR DD family, utilizing an AVR CPU with a hardware multiplier. It features 64 KB of in-system self-programmable Flash memory, 8 KB of SRAM, and 256 bytes of EEPROM. The device operates at clock speeds up to 24 MHz within a supply voltage range of 1.8V to 5.5V. It includes a 12-bit differential ADC, a 10-bit DAC, analog comparators, and multiple communication interfaces including USART, SPI, and TWI. The -E suffix indicates an extended temperature range of -40°C to +125°C, housed in a TQFP-32 package.

Feature Summary

• Multi-Voltage I/O (MVIO) capability on Port C enables direct interfacing with devices operating at different voltage levels without external level shifters.
• Configurable Custom Logic (CCL) provides four programmable Look-up Tables for implementing complex digital logic functions independently of the CPU.
• Event System allows for predictable, CPU-independent signaling between peripherals, reducing system latency and processing overhead.
• Integrated Zero-Cross Detector (ZCD) facilitates precise timing control for AC power applications and motor drive systems.

Applications

• Industrial control systems requiring robust real-time processing
• Smart home appliances and IoT end nodes
• Automotive electronics meeting functional safety standards
• Motor control applications utilizing ZCD and advanced timers

Procurement Notes

Verify that the ordering suffix 'E' corresponds to the extended industrial temperature range (-40°C to +125°C) as defined in the datasheet designation table. Confirm the package style 'PT' matches the required TQFP-32 footprint. Ensure compatibility with existing designs by checking pin and feature compatibility if migrating from other AVR DD family members.

Selection Notes

Select this component when high flash capacity (64 KB) and extensive RAM (8 KB) are required for complex algorithms or data logging. The extended temperature rating makes it suitable for harsh environments where standard industrial parts may fail. Consider the MVIO feature if the design involves mixed-voltage domains to simplify board layout.

Part Context

This part belongs to the AVR DD family, which emphasizes low-power performance and intelligent analog features. The family supports vertical migration without code modification due to full pin and feature compatibility across variants. The AVR64DD32 represents the highest memory configuration in the 32-pin lineup, offering maximum peripheral availability for demanding applications.

Replacement Considerations

AVR64DD32T-I/PT offers identical functionality but with an industrial temperature range (-40°C to +85°C). AVR32DD32-E/PT provides reduced memory (32 KB Flash, 4 KB SRAM) while maintaining pin compatibility. Verify thermal requirements before substituting with lower temperature grade parts.
