Overview
The AVR128DA48S-I/PT is an 8-bit microcontroller from the AVR DA(S) family, featuring a 24 MHz CPU, 128 KB Flash, 16 KB SRAM, and 512 B EEPROM. It includes a 12-bit ADC, three analog comparators, one DAC, three zero-cross detectors, and a Peripheral Touch Controller. The device supports up to 41 I/O pins, operates between 1.8 V and 5.5 V, and functions within -40°C to +85°C. It utilizes a single-pin UPDI for programming and debugging.
Feature Summary
- Includes Program and Debug Interface Disable (PDID) for secure firmware protection
- Features a Peripheral Touch Controller with Driven Shield+ technology
- Supports Event System for inter-peripheral signaling without CPU intervention
- Integrates multiple voltage references including 1.024V, 2.048V, 2.500V, and 4.096V
Applications
- Secure firmware upgrade implementations requiring PDID
- Capacitive touch interface designs using PTC
- Power control applications utilizing TCD and ZCD
- Industrial monitoring systems operating in industrial temperature ranges
Procurement Notes
Verify the specific ordering suffix 'S' confirms the inclusion of the PDID feature as documented in the datasheet. Ensure the package style matches the required pin count and thermal specifications. Confirm that the industrial temperature range aligns with the operational environment requirements before finalizing procurement.
Selection Notes
Select this component when secure code execution via PDID is mandatory. Compare memory sizes against other DA family variants if lower capacity suffices. Verify that the 48-pin package provides sufficient I/O availability for the target design. Consider the 24 MHz maximum frequency relative to system timing constraints.
Part Context
This part belongs to the AVR128DA28/32/48/64(S) series, which offers vertical migration compatibility without code modification. The 'S' designation specifically indicates the presence of the PDID security feature. These devices share a common architecture with varying pin counts and peripheral sets across the family.
Replacement Considerations
AVR128DA48-I/PT serves as a direct substitute lacking the PDID feature. Other AVR DA family members offer different pin counts or memory configurations but maintain architectural compatibility.
