AVR128DA32S-E/PT

Overview

The AVR128DA32S-E/PT is an 8-bit microcontroller from the AVR DA(S) family, featuring a 32-pin TQFP package. It operates at up to 24 MHz with a supply voltage range of 1.8V to 5.5V and supports extended temperatures from -40°C to +125°C. The device includes 128 KB of Flash memory, 16 KB of SRAM, and 512B of EEPROM. Key peripherals include a 12-bit ADC, three analog comparators, one DAC, six USARTs, two SPI interfaces, two TWI/I2C modules, and a Peripheral Touch Controller (PTC).

Feature Summary

• Includes Program and Debug Interface Disable (PDID) for secure firmware protection.
• Features a Peripheral Touch Controller (PTC) with Driven Shield+ technology.
• Supports vertical migration within the AVR DA(S) family without code modification.

Applications

• Secure firmware upgrade implementations requiring PDID.
• Capacitive touch interface designs using PTC.
• Industrial control systems operating in extended temperature environments.

Procurement Notes

Verify that the ordering suffix 'S' confirms the inclusion of the PDID feature, as this distinguishes it from standard variants. Ensure the 'E' suffix matches the required extended temperature range specifications for your application environment before finalizing procurement.

Selection Notes

Select this component when 128 KB of program memory and 16 KB of RAM are required alongside extensive communication interfaces. The 32-pin form factor offers a balance between pin count and physical footprint. Consider the PDID requirement if hardware-level security against unauthorized debugging access is necessary.

Part Context

This part belongs to the AVR128DA28/32/48/64(S) series, which shares architectural compatibility across different pin counts and memory sizes. The 'S' designation specifically indicates the presence of the PDID security feature, while the 'E' suffix denotes the extended industrial temperature rating compared to the standard 'I' variant.
