AVR128DB32T-E/RXB

Overview

The AVR128DB32T-E/RXB is an 8-bit microcontroller from the AVR DB family, featuring a 128 KB Flash program memory, 16 KB SRAM, and 512 bytes of EEPROM. It operates at clock speeds up to 24 MHz with a supply voltage range of 1.8V to 5.5V. The device includes a 12-bit differential ADC, a 10-bit DAC, three analog comparators, and multiple timer/counters. It utilizes a single-pin UPDI interface for programming and debugging.

Feature Summary

• Features Multi-Voltage I/O (MVIO) on Port C for flexible voltage level interfacing.
• Includes an Analog Signal Conditioning peripheral with op amps and internal resistor ladders.
• Supports CPU-independent inter-peripheral signaling via the Event System.
• Provides automated cyclic redundancy check (CRC) scanning for Flash program memory.

Applications

• Digital power conversion systems
• Industrial control applications
• Smart sensor nodes

Procurement Notes

Verify the specific suffix 'E/RXB' against the manufacturer's official documentation to confirm package type and temperature grade. Ensure compatibility with existing design constraints before procurement. Cross-reference the datasheet revision to validate all electrical specifications and pinout configurations.

Selection Notes

Select this component for designs requiring high-performance 8-bit processing with advanced analog capabilities. Consider the 32-pin VQFN package for space-constrained layouts. Evaluate the need for multi-voltage I/O support and the extensive peripheral set including event-driven architectures.

Part Context

This part belongs to the AVR128DB series, which offers vertical migration within the family without code modification. It shares architectural similarities with other AVR DB devices but provides specific memory and pin counts tailored for mid-range embedded applications.
