AVR64DD32-E/RXB

Overview

The AVR64DD32-E/RXB is an 8-bit microcontroller from the AVR DD family, utilizing an AVR CPU with a hardware multiplier operating at clock speeds up to 24 MHz. It features 64 KB of in-system self-programmable Flash memory, 8 KB of SRAM, and 256 bytes of EEPROM. The device is housed in a 32-pin VQFN package (RXB) and supports an extended industrial temperature range of -40°C to +125°C (E). Key peripherals include a 12-bit differential ADC, a 10-bit DAC, two USARTs, SPI, TWI/I2C, and a Configurable Custom Logic block.

Feature Summary

• Multi-Voltage I/O (MVIO) capability on Port C enables direct communication with devices operating at different voltage levels without external level shifters.
• Integrated Event System allows for CPU-independent inter-peripheral signaling, reducing system latency and processing overhead.
• Configurable Custom Logic provides four programmable Look-up Tables for implementing custom digital logic functions independently of the CPU.

Applications

• Industrial control systems requiring robust noise immunity and multi-voltage interfacing
• Smart home appliances and IoT end nodes needing low-power operation and versatile connectivity
• Automotive applications demanding high-temperature reliability and functional safety compliance

Procurement Notes

Verify that the ordering suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) and 'RXB' denotes the 32-pin VQFN package. Confirm RoHS compliance status through official Microchip documentation prior to integration. Ensure design compatibility with the specific pinout and electrical characteristics defined in the datasheet.

Selection Notes

Select this component when application requirements demand high peripheral density within a compact 32-pin footprint. The extended temperature rating makes it suitable for harsh environments where standard industrial grades are insufficient. Consider the MVIO feature if the system architecture involves mixed-voltage domains to simplify board layout.

Part Context

This part belongs to the AVR DD family, which emphasizes vertical migration capabilities across pin counts while maintaining code compatibility. It represents a modern evolution of the AVR architecture, integrating advanced analog and digital peripherals designed for real-time control applications in consumer, industrial, and automotive sectors.

Replacement Considerations

AVR64DD32-I/RXB offers identical specifications but operates within the industrial temperature range (-40°C to +85°C).
