AVR128DA48S-E/PT

Overview

The AVR128DA48S-E/PT is an 8-bit microcontroller from the AVR DA(S) 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, one DAC, and three zero-cross detectors. It supports extended temperature operation from -40°C to +125°C and utilizes a TQFP-48 package.

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 an Event System for CPU-independent inter-peripheral signaling and Configurable Custom Logic (CCL).
Supports automated cyclic redundancy check (CRC) scanning for Flash memory integrity verification.

Applications

Secure firmware upgrade implementations requiring code authentication.
IoT applications utilizing capacitive touch interfaces.
Power control systems using optimized timer peripherals.
Industrial devices operating in extended temperature environments.

Procurement Notes

Verify that the ordering suffix 'S' confirms the inclusion of the PDID security feature. Ensure the '-E' suffix matches the required extended temperature range of -40°C to +125°C. Confirm the '/PT' designation corresponds to the TQFP-48 package style. Cross-reference the datasheet DS40002183 to validate all specifications before integration.

Selection Notes

Select this component when 128 KB of program memory and 16 KB of data storage are required within a 48-pin footprint. The extended temperature rating makes it suitable for harsh industrial environments. The integrated PDID feature is essential for applications demanding high-level security against physical or remote attacks on the firmware.

Part Context

This device belongs to the AVR128DA28/32/48/64(S) family, which offers vertical migration without code modification. The 'S' variant specifically adds the PDID capability compared to standard DA devices. It shares pin compatibility with other members of the DA series, allowing for flexible design scaling across different pin counts.
