Overview
The AVR128DA48T-I/6LX is an 8-bit microcontroller from the AVR DA family, featuring a 128 KB Flash memory, 16 KB SRAM, and 512 B EEPROM. It operates at up to 24 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes a 12-bit ADC with 18 channels, three analog comparators, three zero-cross detectors, and a Peripheral Touch Controller. It supports multiple communication interfaces including USART, SPI, and TWI/I2C.
Feature Summary
- Features a flexible low-power architecture with an Event System for CPU-independent inter-peripheral signaling.
- Includes intelligent analog features such as a 12-bit differential ADC, analog comparators, and zero-cross detectors.
- Supports capacitive touch applications via the Peripheral Touch Controller with Driven Shield+ technology.
- Provides automated cyclic redundancy check (CRC) scanning for Flash memory integrity verification.
Applications
- Industrial control systems requiring robust peripheral integration
- Smart home devices utilizing capacitive touch interfaces
- Power control applications leveraging specialized timer counters
Procurement Notes
Verify the ordering suffix 'T' indicates tape and reel packaging and '6LX' denotes the VQFN48 package. Confirm the 'I' suffix specifies the industrial temperature range of -40°C to +85°C. Ensure compatibility with the UPDI programming interface requirements during procurement planning.
Selection Notes
Select this component when vertical migration within the AVR DA family is required without code modification. Consider the 48-pin VQFN package for space-constrained designs. Evaluate the 128 KB Flash capacity against application memory needs before choosing over smaller variants in the series.
Part Context
This part belongs to the AVR128DA28/32/48/64 series, designed for full pin and feature compatibility across the family. It utilizes the latest Microchip technologies for enhanced performance. The device integrates a hardware multiplier and single-cycle I/O access for efficient processing.
Replacement Considerations
AVR128DA48-E/6LX offers extended temperature range (-40°C to +125°C). AVR128DA48-I/PT provides the same electrical specifications in a TQFP-48 package. Verify package dimensions and thermal characteristics when substituting.
