AVR32DB32T-E/PT

Overview

The AVR32DB32T-E/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, three analog comparators, a 10-bit DAC, and up to three op amps. It supports multiple communication interfaces including USART, SPI, and TWI/I2C. The component is housed in a TQFP-32 package and is rated for extended industrial temperature operation from -40°C to +125°C.

Feature Summary

• Features Multi-Voltage I/O (MVIO) on Port C for flexible voltage level interfacing.
• Includes Analog Signal Conditioning peripherals with configurable 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 integrity.

Applications

• Industrial control systems requiring robust analog signal processing
• Power management applications utilizing zero-cross detection and PWM generation
• Sensor interface designs leveraging high-resolution differential ADC inputs
• Embedded systems needing reliable data retention and self-programmable Flash

Procurement Notes

Verify the specific ordering suffix 'E' confirms the extended temperature range (-40°C to +125°C) and 'PT' denotes the TQFP-32 package style. Confirm that the tape and reel carrier type matches your automated assembly requirements. Ensure compatibility with UPDI programming tools for this specific Microchip variant.

Selection Notes

Select this part when extended temperature performance is required alongside the standard AVR32DB feature set. Consider the TQFP-32 package if through-hole or larger pitch surface mount assembly is preferred over VQFN options. Verify that the 24 MHz operating speed meets the timing constraints of the target application logic.

Part Context

This component belongs to the AVR32DB family, which offers vertical migration compatibility within the series. It shares architectural similarities with other AVR DB devices but is distinguished by its specific pin count and memory configuration. The family emphasizes low-power operation and advanced analog subsystems for embedded control tasks.

Replacement Considerations

AVR32DB32-I/PT serves as the industrial temperature variant of this component. Other members of the AVR32DB family may offer compatible functionality with different pin counts or memory sizes, provided code adaptation is acceptable.
