AVR128DA48T-I/PT

Overview

The AVR128DA48T-I/PT is an 8-bit microcontroller from the AVR DA family, featuring a 48-pin TQFP package. It includes 128 KB of Flash memory, 16 KB of SRAM, and 512 B of EEPROM. The device operates at a maximum frequency of 24 MHz with a supply voltage range of 1.8 V to 5.5 V. Key peripherals include five USARTs, two SPI interfaces, two TWI/I2C controllers, one 12-bit ADC with 18 channels, one 10-bit DAC, three analog comparators, and two zero-cross detectors. It supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

Features a flexible architecture with an Event System for CPU-independent inter-peripheral signaling.
Includes intelligent analog features such as a 12-bit differential ADC and configurable custom logic (CCL).
Supports Peripheral Touch Controller (PTC) technologies for capacitive touch applications.
Utilizes a single-pin Unified Program and Debug Interface (UPDI) for programming and debugging.

Applications

IoT application prototyping
Industrial control systems
Power control applications

Procurement Notes

Verify the 'T' suffix indicates tape and reel packaging rather than tube or tray. Confirm the 'I' suffix corresponds to the industrial temperature range (-40°C to +85°C). Ensure the PT package style matches the required TQFP-48 footprint. Cross-reference the datasheet revision DS40002183B for accurate pinout and electrical specifications.

Selection Notes

Select this component when vertical migration within the AVR DA family is required without code modification. Choose this part if 128 KB of Flash and 16 KB of SRAM are necessary for the application. Consider this MCU for designs requiring multiple communication interfaces like USART and TWI alongside advanced analog capabilities.

Part Context

This device belongs to the AVR128DA28/32/48/64 series, which offers full pin and feature compatibility across the family. The AVR128DA48 variant specifically provides 48 pins, balancing peripheral count with package size. It shares the same core architecture and memory organization as other members in the AVR DA family.
