AVR16EA32-I/RXB

Overview

The AVR16EA32-I/RXB 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, three USARTs, one SPI, and one TWI interface. It utilizes a 32-pin VQFN package and supports industrial temperature ranges.

Feature Summary

• AVR CPU with hardware multiplier running at up to 20 MHz
• True read-while-write operation for Flash memory
• Event System for CPU-independent inter-peripheral signaling
• Configurable Custom Logic (CCL) with programmable Look-up Tables

Applications

• Industrial control systems
• Consumer electronics
• Smart energy applications
• IoT devices

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and carrier configuration. Ensure the temperature grade matches the application requirements. Confirm that the 'Preliminary' status in source documents does not impact final production qualification or long-term availability commitments.

Selection Notes

Select this component for designs requiring vertical migration within the AVR EA family without code modification. Consider the 32-pin VQFN package for space-constrained layouts. Evaluate the peripheral count against system needs, noting that horizontal migration reduces available features and pin counts.

Part Context

This part belongs to the AVR16EA28/32/48 series, which shares architectural compatibility. It offers 16 KB Flash, distinguishing it from the 32 KB and 64 KB variants. The device integrates advanced digital peripherals and accurate analog subsystems typical of the AVR EA Family.
