Overview
The AVR32EA48T-E/PT is an 8-bit microcontroller from the AVR EA family, featuring a 20 MHz AVR CPU with hardware multiplier. It includes 32 KB of Flash memory with read-while-write capability, 4 KB of SRAM, and 512 bytes of EEPROM. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports an extended temperature range of -40°C to +125°C. It is housed in a 48-pin TQFP package and utilizes tape-and-reel packaging.
Feature Summary
- Features a flexible low-power architecture with Event System and advanced digital peripherals for efficient real-time control.
- Includes a 12-bit differential ADC with programmable gain amplifier and multiple voltage references for accurate analog subsystems.
- Supports single-pin Unified Program and Debug Interface (UPDI) for programming and debugging operations.
Applications
- Real-time control systems
- Sensor nodes
- Secondary safety monitoring applications
Procurement Notes
Verify the specific ordering suffix 'E' confirms the extended temperature rating (-40°C to +125°C) and 'T' indicates tape-and-reel packaging. Confirm the datasheet version matches the required specifications before finalizing procurement orders.
Selection Notes
Select this component when extended industrial temperature operation is required alongside standard AVR EA family features. Ensure the 48-pin TQFP package fits the board layout constraints and that the 32 KB Flash capacity meets application code requirements.
Part Context
This part belongs to the AVR EA family, which offers vertical migration without code modification across different pin counts and memory sizes. It shares architectural similarities with other devices in the series but is distinguished by its specific memory configuration and extended temperature rating.
Replacement Considerations
AVR32EA48-I/PT provides identical functionality with an industrial temperature range (-40°C to +85°C). AVR64EA48T-E/PT offers increased memory capacity while maintaining the same package and extended temperature rating.
FAQ
What does the 'E' suffix indicate in the part number?
The 'E' suffix denotes an extended temperature range operating from -40°C to +125°C.
Does this device support simultaneous reading and writing to Flash?
Yes, it features true read-while-write operation for the 32 KB Flash memory.
