AVR128DA64ST-E/5LX

Overview

The AVR128DA64ST-E/5LX is an 8-bit microcontroller from the AVR DA(S) family, utilizing the AVR CPU with a hardware multiplier running at up to 24 MHz. It features 128 KB of Flash memory, 16 KB of SRAM, and 512B of EEPROM. The device operates within a supply voltage range of 1.8V to 5.5V and supports an extended temperature range of -40°C to +125°C. It includes a 12-bit differential ADC with 22 channels, three analog comparators, one DAC, and multiple communication interfaces including USART, SPI, and TWI.

Feature Summary

• Supports vertical migration without code modification due to full pin and feature compatibility across the AVR DA(S) family.
• Integrates intelligent analog features including a Peripheral Touch Controller (PTC) with Driven Shield+ technology for capacitive touch applications.
• Provides advanced digital peripherals such as Configurable Custom Logic (CCL) and an Event System for CPU-independent inter-peripheral signaling.
• Includes security features like Program and Debug Interface Disable (PDID) to protect against unauthorized access and firmware tampering.

Applications

• Industrial control systems requiring robust peripheral integration
• Smart home appliances with capacitive touch interfaces
• IoT devices needing secure firmware updates
• Automotive applications operating in extended temperature environments

Procurement Notes

Verify the ordering suffix 'S' indicates the presence of the PDID feature and '5LX' specifies the VQFN48 package style. Confirm the 'E' suffix denotes the extended temperature range (-40°C to +125°C). Ensure the specific variant matches the required package and security features for your design.

Selection Notes

Select this component when 128 KB of Flash and 16 KB of SRAM are required alongside a high number of I/O pins. The extended temperature rating makes it suitable for harsh environments. Consider the PDID feature if security against debug interface attacks is a priority. Verify that the VQFN48 package fits the PCB layout constraints.

Part Context

This part belongs to the AVR128DA28/32/48/64(S) series, which offers vertical migration capabilities. The 'S' designation specifically adds the Program and Debug Interface Disable (PDID) security feature. The '5LX' suffix identifies the VQFN48 package type, distinguishing it from other pin counts or packages in the same memory configuration.
