AVR64DD32T-I/RXB

Overview

AVR64DD32T-I/RXB is an 8-bit AVR microcontroller featuring a hardware multiplier CPU running at up to 24 MHz. It includes 64 KB of self-programmable Flash, 8 KB of SRAM, and 256 bytes of EEPROM. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports industrial temperatures from -40°C to +85°C. It utilizes a 32-pin VQFN package (RXB suffix) and provides up to 26 programmable I/O pins with Multi-Voltage I/O capabilities.

Feature Summary

• Multi-Voltage I/O (MVIO) enables bidirectional communication across different power domains without external level shifters.
• Configurable Custom Logic (CCL) allows for custom digital logic implementation using Look-up Tables.
• Event System (EVSYS) facilitates CPU-independent inter-peripheral signaling to reduce system latency.
• Integrated analog peripherals include a 12-bit differential ADC, 10-bit DAC, Analog Comparator, and Zero-Cross Detector.

Applications

• Industrial control systems requiring real-time processing
• Smart home appliances with multi-voltage domain requirements
• IoT terminal nodes utilizing low-power sleep modes
• Sensor applications involving signal conditioning

Procurement Notes

Verify the specific ordering suffix RXB corresponds to the 32-pin VQFN package configuration required for your PCB layout. Confirm that the 'I' designation matches the necessary industrial temperature range specifications for your operational environment. Ensure compatibility with existing design tools by referencing the official datasheet DS40002315C for pinout and electrical characteristics.

Selection Notes

Select this component when 64 KB of program memory and 8 KB of data RAM are required within a compact 32-pin footprint. The MVIO feature is essential for designs interfacing with mixed-voltage peripherals. Consider the integrated Event System and CCL if minimizing CPU intervention for peripheral tasks is a priority. Verify that the 24 MHz maximum clock speed meets the timing constraints of your application.

Part Context

This part belongs to the AVR DD Family, which emphasizes vertical migration compatibility across pin counts and memory sizes. The AVR64DD32 variant represents the high-memory option in the 32-pin package lineup. It shares architectural similarities with lower-density devices like the AVR32DD32 but offers double the Flash and SRAM capacity while maintaining identical pinouts.

Replacement Considerations

AVR64DD32T-I/PT serves as a direct pin-compatible alternative in a TQFP-32 package. Other family members such as AVR32DD32 or AVR16DD32 offer functional compatibility with reduced memory capacities. Migration between these variants typically requires no code modification due to full pin and feature compatibility within the series.
