AVR128DA64S-E/5LX

Overview

The AVR128DA64S-E/5LX is an 8-bit microcontroller from the AVR DA(S) family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 128 KB of Flash memory, 16 KB of SRAM, and 512 B of EEPROM. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports an extended temperature range of -40°C to +125°C. It utilizes a 48-pin VQFN package (designated by the 5LX suffix) and provides up to 41 programmable I/O pins.

Feature Summary

• Includes Program and Debug Interface Disable (PDID) for secure firmware protection against unauthorized access.
• Features a Peripheral Touch Controller (PTC) supporting capacitive touch buttons, sliders, wheels, and 2D surfaces.
• Integrates intelligent analog peripherals including a 12-bit differential ADC, three analog comparators, and a 10-bit DAC.
• Supports flexible inter-peripheral signaling through an Event System and Configurable Custom Logic (CCL).

Applications

• Secure embedded systems requiring firmware authentication
• Capacitive touch user interface designs
• Industrial control applications operating in extended temperatures
• Power management devices utilizing zero-cross detection

Procurement Notes

Verify that the ordering suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) and '5LX' indicates the 48-pin VQFN package. Confirm the 'S' designation ensures the inclusion of the PDID security feature. Cross-reference the specific datasheet revision DS40002183E to ensure compatibility with your design requirements.

Selection Notes

Select this component when vertical migration within the AVR DA(S) family is required without code modification. Choose this part if the application demands high pin counts (up to 41 I/Os) and advanced analog signal conditioning capabilities alongside robust security features like PDID. Ensure the 48-pin VQFN footprint fits the PCB layout constraints.

Part Context

This device belongs to the AVR128DA28/32/48/64(S) series, which offers horizontal and vertical migration paths. The 'S' variant specifically adds the PDID security feature compared to standard versions. It shares architectural similarities with other AVR DA family members but is distinguished by its specific memory size and package configuration.
