AVR128DA32T-I/RXB

Overview

The AVR128DA32T-I/RXB is an 8-bit microcontroller from the AVR DA family, featuring a 32-pin VQFN package. It includes 128 KB of Flash memory, 16 KB of SRAM, and 512 B of EEPROM. The device operates at a maximum frequency of 24 MHz with a supply voltage range of 1.8 V to 5.5 V. It provides 27 general-purpose I/O pins and supports an industrial temperature range of -40°C to +85°C.

Feature Summary

Integrates a hardware multiplier for efficient arithmetic operations within the AVR CPU architecture.
Features a Peripheral Touch Controller (PTC) supporting capacitive touch sensing technologies.
Includes an Event System for predictable inter-peripheral signaling independent of the CPU.
Supports automated cyclic redundancy check (CRC) scanning for Flash memory integrity.

Applications

Industrial control systems requiring robust peripheral integration
Consumer electronics utilizing capacitive touch interfaces
Battery-powered devices benefiting from low-power sleep modes

Procurement Notes

Verify that the 'RXB' suffix corresponds to the 32-pin VQFN package and the 'T' indicates tape and reel packaging. Confirm the 'I' suffix matches the required industrial temperature range specifications for your application environment before finalizing orders.

Selection Notes

Select this component when a balance of moderate pin count and high memory capacity is needed. It offers vertical migration compatibility within the AVR DA family, allowing code reuse across different pin counts while maintaining feature parity.

Part Context

This part belongs to the AVR128DA series, which shares architectural similarities with other AVR DA variants. It is designed for applications needing enhanced analog features and digital peripherals compared to legacy AVR devices, offering improved performance through its optimized instruction set.
