AVR128DB48T-E/PT

Overview

The AVR128DB48T-E/PT is an 8-bit microcontroller from the AVR DB family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 128 KB Flash, 16 KB SRAM, and 512 B EEPROM. The device operates between 1.8 V and 5.5 V in a TQFP-48 package. Key peripherals include a 12-bit ADC, 10-bit DAC, three analog comparators, up to six USARTs, two SPIs, and two TWI interfaces.

Feature Summary

Supports multi-voltage I/O (MVIO) on Port C for flexible interfacing.
Integrates an Event System for CPU-independent peripheral signaling.
Includes Configurable Custom Logic (CCL) with Look-up Tables.
Features Analog Signal Conditioning with op amps and internal resistor ladders.

Applications

Industrial control systems requiring robust analog signal processing.
Smart energy metering applications utilizing zero-cross detection.
Battery-powered devices benefiting from low-power sleep modes.
Motor control implementations using optimized PWM timers.

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm the '-E' designation corresponds to the extended temperature range of -40°C to +125°C as per the official datasheet specifications. Ensure compatibility with the UPDI programming interface for development and debugging purposes.

Selection Notes

Select this model for designs requiring vertical migration within the AVR DB family without code modification. It is suitable for applications needing high pin counts and extensive analog peripherals in a compact 48-pin package. Consider the Event System capabilities if deterministic inter-peripheral communication is required without CPU intervention.

Part Context

This component belongs to the AVR128DB28/32/48/64 series, which shares full pin and feature compatibility across the family. The 48-pin variant offers a balance between memory capacity and I/O availability. It utilizes the Unified Program and Debug Interface (UPDI) for simplified single-pin programming and debugging workflows.
