AVR64DD32-I/PT

Overview

The AVR64DD32-I/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 with 23 channels, a 10-bit DAC, analog comparators, and zero-cross detectors. Communication interfaces include two USARTs, one SPI, and one TWI/I2C. The component is housed in a 32-pin TQFP package.

Feature Summary

• Multi-Voltage I/O (MVIO) capability on Port C for level shifting without external converters
• Configurable Custom Logic (CCL) with four Look-up Tables for custom digital logic implementation
• Event System (EVSYS) enabling CPU-independent peripheral signaling to reduce latency
• Integrated Zero-Cross Detector (ZCD) and Analog Comparator for power control applications

Applications

• Industrial control systems requiring real-time processing
• Smart home appliances with multi-voltage domain requirements
• Internet of Things (IoT) terminal nodes
• Power control circuits utilizing zero-cross detection

Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature range (-40°C to +85°C). Confirm the 'PT' suffix corresponds to the TQFP-32 package style. Ensure compatibility with existing firmware by checking pin and feature alignment within the AVR DD family for vertical migration. Validate that the required peripherals match the specific allocation for the 32-pin variant.

Selection Notes

Select this model when 64 KB of program memory and 8 KB of RAM are required for complex logic. Choose the 32-pin TQFP package if higher pin counts and thermal performance are needed compared to smaller packages. Opt for this device over lower-memory variants if the application demands extensive data storage or complex algorithm execution. Consider the MVIO feature if interfacing with mixed-voltage sensors or actuators.

Part Context

This component belongs to the AVR DD Family, designed for low-power and high-performance 8-bit applications. It shares architectural similarities with other devices in the series, allowing for vertical migration without code modification. The family emphasizes intelligent analog features and advanced digital peripherals, targeting cost-sensitive yet feature-rich embedded designs.

Replacement Considerations

AVR64DD32T-I/PT: Identical electrical specifications and package; differs only in tape-and-reel packaging instead of tube.
