AVR32DB32T-I/PT

Overview

The AVR32DB32T-I/PT is an 8-bit microcontroller from the AVR DB family, featuring a 32 KB Flash program memory, 4 KB SRAM, and 512 bytes of EEPROM. It operates at a maximum clock frequency of 24 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes a 12-bit ADC with 13 channels, a 10-bit DAC, three op amps, and three zero-cross detectors. It supports I2C, SPI, and serial interfaces, housed in a TQFP-32 package.

Feature Summary

Features Multi-Voltage I/O (MVIO) on Port C for flexible logic level interfacing.
Includes advanced analog subsystems such as a 12-bit differential ADC and configurable op amps.
Supports CPU-independent inter-peripheral signaling via the Event System.
Provides automated cyclic redundancy check (CRC) scanning for Flash program memory.

Applications

Applications requiring multi-voltage I/O compatibility
Power control systems utilizing PWM Timer/Counter type D
Industrial communication using RS-485 or LIN client modes

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm the 'I' suffix corresponds to the industrial temperature range of -40°C to +85°C. Ensure the component matches the exact datasheet revision DS40002301B for accurate pinout and electrical specifications during integration.

Selection Notes

Select this model for designs needing vertical migration within the AVR DB family without code modification. Consider the 32-pin TQFP package for surface-mount assembly. Evaluate the 12-bit ADC resolution and MVIO capabilities against application requirements for analog signal processing and mixed-voltage environments.

Part Context

This component belongs to the AVR32DB28/32/48 series within the broader AVR DB microcontroller family. It shares architectural similarities with other devices in the family, allowing for horizontal and vertical migration based on pin count and memory size requirements while maintaining feature compatibility.
