Overview
The AVR32DA48-I/PT is an 8-bit microcontroller from the AVR DA family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 32 KB of Flash memory, 4 KB of SRAM, and 512 B of EEPROM. The device provides up to 41 programmable I/O pins in a TQFP-48 package. Key peripherals include a 12-bit differential ADC, three analog comparators, a 10-bit DAC, two Zero-Cross Detectors, and a Peripheral Touch Controller. Operating voltage ranges from 1.8 V to 5.5 V across an industrial temperature range of -40°C to +85°C.
Feature Summary
- Supports vertical migration within the AVR DA(S) family without code modification due to full pin and feature compatibility.
- Integrates intelligent analog features including a 12-bit differential ADC with PGA and multiple voltage references for precise signal acquisition.
- Includes advanced digital peripherals such as Configurable Custom Logic (CCL) and an Event System for CPU-independent inter-peripheral signaling.
Applications
- Industrial control systems requiring robust peripheral integration
- Smart home appliances utilizing capacitive touch interfaces
- Power monitoring applications leveraging zero-cross detection
Procurement Notes
Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure the procurement channel sources genuine components directly from authorized distributors or the manufacturer to avoid counterfeit devices. Confirm that the required firmware development tools support the UPDI interface for programming and debugging.
Selection Notes
Select this component when a balance of moderate memory capacity and extensive analog/digital peripherals is required. The 48-pin form factor supports high I/O counts suitable for complex interfaces. Consider the AVR32DA48 over smaller variants if additional USART, SPI, or TWI channels are necessary for system connectivity.
Part Context
This device belongs to the AVR DA(S) family, which utilizes the latest Microchip technologies for low-power operation. It shares architectural similarities with the AVR DB and EA families but offers enhanced peripheral sets like the Peripheral Touch Controller. The family emphasizes flexibility through event-driven architectures and secure boot capabilities via PDID.

FAQ
Does the AVR32DA48-I/PT support simultaneous host and client operation on TWI?
Yes, the device includes up to two TWI interfaces capable of independent host and client operation (dual mode).
What is the maximum operating frequency of the AVR32DA48-I/PT?
The AVR CPU runs at a maximum frequency of 24 MHz.
Is the Program and Debug Interface Disable (PDID) feature available on the standard AVR32DA48?
No, PDID is only available on AVR DAS devices; the standard AVR32DA48 does not include this security feature.
