AVR64EA32-E/RXB

Overview

The AVR64EA32-E/RXB is an 8-bit microcontroller from the AVR EA family, featuring a 32-pin VQFN package. It includes 64 KB of Flash memory with read-while-write capability, 6 KB of SRAM, and 512 bytes of EEPROM. The device operates at clock speeds up to 20 MHz within a supply voltage range of 1.8 V to 5.5 V. Key peripherals include a 12-bit differential ADC with PGA, a 10-bit DAC, two analog comparators, three USARTs, one SPI, and one TWI interface.

Feature Summary

• AVR CPU with hardware multiplier running at up to 20 MHz
• Flexible low-power architecture with Event System and advanced digital peripherals
• True read-while-write operation for non-volatile memory access
• Configurable Custom Logic (CCL) with programmable Look-up Tables

Applications

• Real-time control systems
• Sensor nodes
• Secondary safety monitoring applications
• Closed-loop control system design

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature rating. Ensure the component matches the required industrial or extended temperature specifications. Confirm that the datasheet version aligns with current manufacturing revisions before finalizing procurement orders.

Selection Notes

Select this model when 32 pins are required alongside 64 KB of Flash memory. It supports vertical migration within the AVR EA family without code modification. Consider the 12-bit ADC resolution and dual-mode TWI capabilities for precise analog signal processing and flexible communication requirements.

Part Context

This component belongs to the AVR64EA28/32/48 series, which shares a common architecture across different pin counts. The 'E' designation indicates an extended temperature range of -40°C to +125°C. The 'RXB' suffix specifies the 32-pin VQFN package format.
