AVR16EA32-I/PT

Overview

The AVR16EA32-I/PT is an 8-bit microcontroller from the AVR EA family, featuring a 16 KB Flash memory with read-while-write capability, 2 KB SRAM, and 512 bytes of EEPROM. It operates at clock speeds up to 20 MHz within a supply voltage range of 1.8 V to 5.5 V. The device includes a 12-bit differential ADC with PGA, a 10-bit DAC, two analog comparators, and four CCL LUTs. It supports three USARTs, SPI, and TWI interfaces. The component is housed in a TQFP-32 package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Features a flexible low-power architecture with Event System for CPU-independent peripheral signaling
• Includes accurate analog subsystems such as a 12-bit differential ADC with programmable gain amplifier
• Supports vertical migration without code modification across the AVR EA family pinout variants
• Integrates advanced digital peripherals including Configurable Custom Logic (CCL) Look-up Tables

Applications

• Real-time control systems requiring efficient processing
• Sensor nodes utilizing integrated analog measurement capabilities
• Secondary safety monitoring equipment
• Closed-loop control system designs

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure the procurement channel provides valid datasheets matching DS40002498A. Confirm that the delivered components match the specified industrial temperature range and pin configuration before integration into production assemblies.

Selection Notes

Select this model when a balance of moderate program memory and high-performance analog features is required. The 16 KB Flash size suits applications needing substantial code space without exceeding the capacity of smaller variants. The inclusion of a 12-bit ADC and DAC makes it suitable for precision signal conditioning tasks compared to standard 8-bit controllers lacking these peripherals.

Part Context

This component belongs to the AVR EA family, which utilizes the latest Microchip technologies for enhanced performance. The family offers horizontal and vertical migration paths, allowing designers to scale pin counts and memory sizes while maintaining software compatibility. This specific variant represents the mid-range memory option within the 32-pin footprint lineup.
