AVR64DB32T-I/RXB

Overview

The AVR64DB32T-I/RXB is an 8-bit microcontroller from the AVR DB family, featuring a hardware multiplier and operating at clock speeds up to 24 MHz. It includes 64 KB of Flash memory, 8 KB of SRAM, and 512 bytes of EEPROM. The device utilizes a 32-pin VQFN package (RXB) with tape and reel packaging (T). It supports industrial temperature ranges (-40°C to +85°C) and operates within a supply voltage range of 1.8V to 5.5V.

Feature Summary

• Features a flexible low-power architecture with an Event System for CPU-independent inter-peripheral signaling.
• Includes accurate analog subsystems such as a 12-bit ADC, op amps, and zero-cross detectors.
• Supports vertical migration without code modification across the AVR DB family due to pin and feature compatibility.

Applications

• Industrial control systems requiring robust I/O and analog capabilities
• Power control applications utilizing optimized PWM timers
• General-purpose embedded designs needing multi-voltage I/O support

Procurement Notes

Verify the specific ordering suffixes to confirm the package style, temperature range, and carrier type match your design requirements. Ensure that the industrial temperature rating and voltage specifications align with your system's operational environment before finalizing procurement.

Selection Notes

Select this component when a balance of moderate memory size and extensive peripheral connectivity is required in a compact 32-pin form factor. Consider the AVR DB family's horizontal and vertical migration paths if future scalability or pin count adjustments are anticipated within the same product line.

Part Context

This part belongs to the AVR64DB28/32/48/64 series, which shares core architectural features but varies in pin count and memory capacity. The RXB suffix denotes the 32-pin VQFN package, while the T indicates tape and reel delivery suitable for automated surface-mount assembly processes.
