AVR32EA32-E/RXB

Overview

The AVR32EA32-E/RXB is an 8-bit microcontroller from the AVR EA family, featuring a 20 MHz AVR CPU with hardware multiplier. It includes 32 KB of Flash memory with read-while-write capability, 4 KB of SRAM, and 512 bytes of EEPROM. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports an extended temperature range of -40°C to +125°C. It is housed in a VQFN-32 package and provides 27 general-purpose I/O pins.

Feature Summary

• Supports true read-while-write operation for uninterrupted code execution during flash modifications
• Integrates a 12-bit differential ADC with programmable gain amplifier for high-resolution signal acquisition
• Features an event system enabling CPU-independent inter-peripheral signaling for predictable timing
• Includes configurable custom logic with multiple look-up tables for flexible digital peripheral implementation

Applications

• Industrial control systems requiring extended temperature stability
• Battery-powered devices utilizing low-power sleep modes
• Sensor interfaces using high-resolution analog-to-digital conversion
• Embedded applications needing simultaneous code execution and data logging

Procurement Notes

Verify the specific ordering suffix corresponds to the required package type and temperature grade. Confirm that the 'E' designation matches the extended industrial temperature requirements for your environment. Ensure the '/RXB' suffix aligns with the specified VQFN-32 packaging configuration before finalizing procurement orders.

Selection Notes

Select this component when extended temperature operation up to 125°C is mandatory. Choose this model over the '-I' variant if operating conditions exceed standard industrial limits. Consider the pin count and peripheral availability relative to the AVR32EA28 or AVR32EA48 variants to ensure optimal resource utilization for the specific application constraints.
