AVR16EA48T-I/6LX

Overview

The AVR16EA48T-I/6LX is an 8-bit microcontroller from the AVR EA Family, featuring a 20 MHz AVR CPU with hardware multiplier. It includes 16 KB of Flash memory with read-while-write capability, 2 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 industrial temperature ranges (-40°C to +85°C). Key peripherals include a 12-bit differential ADC with PGA, a 10-bit DAC, three USARTs, SPI, TWI, and an Event System for low-latency inter-peripheral communication.

Feature Summary

• Features a flexible architecture with an Event System for CPU-independent peripheral signaling and Configurable Custom Logic (CCL) for custom digital functions.
• Includes advanced analog subsystems such as a 12-bit differential ADC with programmable gain amplifier and multiple precision voltage references.
• Supports single-pin Unified Program and Debug Interface (UPDI) for programming and debugging, alongside comprehensive clock options including auto-tuning oscillators.

Applications

• Industrial control systems requiring robust analog signal processing
• Battery-powered devices utilizing low-power sleep modes and efficient power management
• Smart sensors and IoT nodes using event-driven architectures

Procurement Notes

Verify the specific package marking and date code against the datasheet revision DS40002498A. Confirm that the 'I' suffix denotes the industrial temperature range and 'T' indicates tape and reel packaging. Ensure compatibility with existing UPDI programming tools and validate pinout assignments for the 48-pin variant before finalizing procurement orders.

Selection Notes

Select this component when vertical migration within the AVR EA family is required without code modification. Choose this model for applications needing high-speed analog acquisition via the differential ADC or precise timing through the RTC and TCA/TCB timers. Consider the 48-pin package only if the design requires the full set of I/O pins and peripheral channels available in this footprint.

Part Context

This part belongs to the AVR16EA28/32/48 series, which shares a common core and peripheral set across different pin counts. The AVR16EA48 variant provides the maximum I/O count for the 16 KB Flash tier. It is designed for seamless integration into Microchip's broader AVR ecosystem, supporting standard development tools and libraries compatible with other AVR devices.
