AVR16DU20T-I/SS

Overview

The AVR16DU20T-I/SS is an 8-bit microcontroller from the AVR DU family, featuring a 16 KB Flash memory, 2 KB SRAM, and 256 B EEPROM. It operates at clock speeds up to 24 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes a USB 2.0 full-speed interface, two USARTs, one SPI, and one TWI/I2C controller. It utilizes a 20-pin SSOP package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

Integrates a USB 2.0 full-speed device-compliant interface for communication.
Includes Program and Debug Interface Disable (PDID) for firmware security.
Features Configurable Custom Logic (CCL) with four Look-up Tables.
Supports Read-While-Write (RWW) operation in Flash memory.

Applications

USB-enabled peripheral devices
Industrial control systems requiring secure firmware updates
Low-power embedded applications

Procurement Notes

Verify the component against the official Microchip datasheet DS40002576A to confirm it is a preliminary release. Ensure the ordering suffix matches the required tape and reel packaging and industrial temperature grade specifications before finalizing procurement.

Selection Notes

Select this model when a 20-pin form factor with integrated USB functionality is required. It provides sufficient memory for basic control tasks while offering advanced security features like PDID. Consider vertical migration within the AVR DU family if larger memory capacities are needed later.

Part Context

This part belongs to the AVR DU family, which shares pin and feature compatibility across different memory sizes. It serves as a modern replacement for legacy AVR devices, offering enhanced peripherals such as the Event System and CCL while maintaining backward compatibility with existing codebases.
