AVR32DB28T-I/SS

Overview

The AVR32DB28T-I/SS is an 8-bit microcontroller from the AVR DB family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 32 KB of Flash, 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 industrial temperatures from -40°C to +85°C. Key peripherals include a 12-bit ADC, 10-bit DAC, three analog comparators, two zero-cross detectors, and multiple communication interfaces such as USART, SPI, and TWI.

Feature Summary

Features Multi-Voltage I/O (MVIO) on Port C for flexible voltage level interfacing.
Includes Analog Signal Conditioning with up to three 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

Industrial control systems requiring robust signal conditioning
Power control applications utilizing PWM Timer/Counter type D
Low-voltage embedded devices operating between 1.8V and 5.5V

Procurement Notes

Verify the specific package style and carrier type when ordering. The 'T' suffix indicates Tape & Reel packaging, while 'SS' denotes SSOP. Confirm the temperature grade 'I' corresponds to the required industrial range of -40°C to +85°C. Ensure compatibility with existing design constraints regarding pin count and peripheral availability before finalizing procurement.

Selection Notes

Select this component for designs requiring vertical migration within the AVR DB family without code modification. It offers a balance of processing speed and analog capabilities suitable for cost-sensitive applications. Consider the 28-pin footprint if space is limited compared to larger variants in the same series.

Part Context

This part belongs to the AVR32DB28/32/48 subset of the broader AVR DB microcontroller family. It shares architectural similarities with higher-memory variants like the AVR64DB28 and AVR128DB28, allowing for potential horizontal or vertical migration depending on project memory requirements.
