Overview
The AVR16DU20-I/REB is an 8-bit microcontroller from the AVR DU family, featuring a hardware multiplier and clock speeds up to 24 MHz. It includes 16 KB of Flash memory with read-while-write capability, 2 KB of SRAM, and 256 bytes of EEPROM. The device operates within a voltage range of 1.8 V to 5.5 V and supports industrial temperatures from -40°C to +85°C. Key peripherals include a USB 2.0 full-speed interface, two USARTs, one SPI, one TWI/I2C, a 10-bit ADC with 11 channels, and four Configurable Custom Logic (CCL) Look-up Tables.
Feature Summary
- Integrates a USB 2.0 full-speed device-compliant interface for crystal-less operation via oscillator tuning.
- Provides Program and Debug Interface Disable (PDID) to prevent unauthorized access to reprogrammable Flash memory over UPDI.
- Features an Event System for CPU-independent inter-peripheral signaling and Configurable Custom Logic with programmable Look-up Tables.
Applications
- Embedded systems requiring secure firmware upgrades with cryptographic validation.
- Crystal-less USB communication applications utilizing internal oscillator tuning.
- Industrial control designs needing robust analog features and low-power sleep modes.
Procurement Notes
Verify that the component matches the preliminary datasheet DS40002576A specifications. Confirm the package style corresponds to the 20-pin VQFN variant. Ensure the temperature grade aligns with industrial requirements. Cross-reference the ordering suffix to confirm tape and reel packaging. Validate all electrical parameters against the official Microchip documentation before integration.
Selection Notes
Select this model when 16 KB of Flash and 2 KB of SRAM are sufficient for the application logic. Choose this part if a USB 2.0 interface is required without external transceivers. Consider this device for designs needing vertical migration compatibility within the AVR DU family. Verify that the 10-bit ADC resolution meets signal processing needs. Ensure the 24 MHz maximum frequency satisfies timing constraints.
Part Context
This component belongs to the AVR DU family, which shares pin and feature compatibility across different memory sizes. It utilizes the AVR CPU architecture with single-cycle I/O access. The family supports vertical migration without code modification between devices like the AVR32DU20 or AVR64DU20. It represents a modern iteration of Microchip's 8-bit MCU portfolio with enhanced security and peripheral integration.

FAQ
Is the USB function available at all supply voltages?
No, the USB function is only available for VDD above 3.0V.
How does the PDID feature enhance security?
PDID prevents access to the device's reprogrammable Flash memory over the Unified Program and Debug Interface (UPDI), protecting against remote attacks and unauthorized code modification.
