Overview
The AVR64DA48-I/PT is an 8-bit microcontroller from the AVR DA family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 64 KB of Flash memory, 8 KB of SRAM, and 512 B of EEPROM. The device provides up to 41 general-purpose I/O pins in a TQFP-48 package. Key peripherals include a 12-bit ADC, three analog comparators, a DAC, six USARTs, two SPI interfaces, and two TWI/I2C modules. It operates within a voltage range of 1.8 V to 5.5 V and supports industrial temperatures from -40°C to +85°C.
Feature Summary
- Supports vertical migration without code modification across the AVR DA(S) family due to full pin and feature compatibility.
- Integrates intelligent analog features including a Peripheral Touch Controller (PTC) for capacitive touch applications.
- Provides advanced digital peripherals such as Configurable Custom Logic (CCL) and an Event System for inter-peripheral signaling.
- Includes security features like Program and Debug Interface Disable (PDID) for secure firmware upgrades.
Applications
- Industrial control systems requiring robust peripheral integration
- Smart home devices utilizing capacitive touch interfaces
- Power control applications using Timer/Counter type D optimization
- Secure embedded systems needing firmware authentication
Procurement Notes
Verify the specific ordering suffix 'I' confirms the industrial temperature range (-40°C to +85°C). Confirm the 'PT' suffix indicates the TQFP package style. Ensure the datasheet version matches the required revision for accurate electrical characteristics. Cross-reference the part number with official Microchip documentation to confirm availability and specifications.
Selection Notes
Select this component when a balance of moderate pin count and high peripheral density is required. It is suitable for designs needing multiple communication interfaces like USART and SPI. Consider the AVR DA family for projects requiring easy migration between different pin counts while maintaining software compatibility.
Part Context
This device belongs to the AVR DA(S) family, which utilizes the latest low-power architecture technologies from Microchip Technology. The family offers flexible configurations across 28, 32, 48, and 64-pin packages. The AVR64DA48 variant specifically targets applications needing 64 KB of Flash and 48 pins, bridging the gap between lower-pin-count and higher-performance devices.
Replacement Considerations
AVR64DA32-I/PT: Offers similar features but with fewer pins and I/O options. AVR64DA64-I/PT: Provides increased I/O capacity and additional peripherals in a larger package. AVR128DA48-I/PT: Features double the Flash memory size while maintaining the same pin count and package.
