AVR32DB48T-E/PT

Overview

The AVR32DB48T-E/PT is an 8-bit microcontroller from the AVR DB family, featuring a 48-pin TQFP package in tape and reel format. It operates within an extended temperature range of -40°C to +125°C. The device includes 32 KB of Flash memory, 4 KB of SRAM, and 512 bytes of EEPROM. It supports a maximum clock frequency of 24 MHz and accepts supply voltages between 1.8 V and 5.5 V. Key peripherals include one 12-bit ADC with 18 channels, one 10-bit DAC, three analog comparators, two zero-cross detectors, and up to three op amps.

Feature Summary

• Features Multi-Voltage I/O (MVIO) on Port C for flexible voltage threshold selection.
• Includes an Event System for CPU-independent inter-peripheral signaling.
• Provides Configurable Custom Logic (CCL) with programmable Look-up Tables.
• Supports automated cyclic redundancy check (CRC) scanning of program memory.

Applications

• Industrial control systems requiring robust peripheral interfaces
• Power management applications utilizing zero-cross detection
• Sensor interfacing using differential ADC inputs
• Motor control implementations with PWM generation

Procurement Notes

Verify the ordering suffix 'T' confirms tape and reel packaging and 'E' indicates the extended temperature grade. Confirm the datasheet revision matches the required specifications. Ensure the manufacturer designation aligns with Microchip Technology standards before finalizing procurement orders.

Selection Notes

Select this variant when extended temperature operation up to 125°C is mandatory. Choose the tape and reel configuration for automated surface-mount assembly processes. Consider the 48-pin footprint if higher pin counts are necessary compared to the 28 or 32-pin variants.

Part Context

This component belongs to the AVR32DB series, which offers vertical migration compatibility within the AVR DB family. It shares architectural similarities with the AVR64DB and AVR128DB devices but provides lower memory capacities. The device utilizes the Unified Program and Debug Interface (UPDI) for programming.
