Overview
The AVR32EA48-I/6LX is an 8-bit microcontroller from the AVR EA series, featuring a 20 MHz AVR CPU with hardware multiplication. It integrates 32 kB of system-in-programmable flash with true read-while-write capability, 4 kB of SRAM, and 512 B of EEPROM. The device operates within a voltage range of 1.8 V to 5.5 V and supports temperatures from -40°C to +85°C. Key peripherals include a 12-bit ADC with PGA, a 10-bit DAC, two analog comparators, three USARTs, SPI, and TWI interfaces, housed in a QFN-48 package.
Feature Summary
- True read-while-write flash memory for uninterrupted code execution during reprogramming
- Integrated event system enabling peripheral-to-peripheral communication without CPU intervention
- Configurable Custom Logic (CCL) providing up to four programmable look-up tables for complex logic functions
- High-precision internal high-frequency oscillator with automatic tuning capabilities
Applications
- Battery-powered sensor nodes requiring low power consumption
- Industrial control systems utilizing analog signal processing
- Smart energy metering applications
- Consumer appliances with multiple communication interfaces
Procurement Notes
Verify the specific suffix '6LX' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with UPDI programming tools. Check RoHS compliance status directly from the manufacturer's datasheet before procurement.
Selection Notes
Select this component for designs requiring simultaneous code execution and data storage updates. The integrated PGA and CCL reduce external component count. Verify that the 48-pin QFN footprint fits the PCB layout constraints and thermal requirements.
Part Context
This part belongs to the AVR EA family, designed for flexible low-power architectures. It shares core features with other EA variants but offers specific pin counts and peripheral configurations suitable for compact embedded applications.
Replacement Considerations
Consult Microchip documentation for direct pin-compatible alternatives within the AVR EA series. Cross-reference specifications carefully when considering competitor devices to ensure functional equivalence.
