AVR16DU28-I/SP

Overview

The AVR16DU28-I/SP is an 8-bit microcontroller from the AVR® DU family, manufactured by Microchip Technology. It features a 16 KB Flash memory, 2 KB SRAM, and 256 bytes of EEPROM. The device operates at clock speeds up to 24 MHz with a supply voltage range of 1.8 V to 5.5 V. It includes a USB 2.0 full-speed device interface, two USARTs, one SPI, and one TWI/I²C peripheral. The component is housed in a 28-pin SPDIP package and supports an industrial temperature range of -40°C to +85°C.

Feature Summary

Integrated USB 2.0 full-speed device controller for direct connectivity without external transceivers
Configurable Custom Logic (CCL) with four Look-up Tables for flexible digital logic implementation
Event System enabling CPU-independent inter-peripheral signaling to reduce software overhead
Program and Debug Interface Disable (PDID) mechanism for enhanced firmware security

Applications

USB Human Interface Device (HID) implementations such as macro keyboards
Battery-powered applications requiring low-power sleep modes and fast wake-up
Industrial control systems utilizing the Event System for predictable peripheral signaling
Secure firmware upgrade scenarios leveraging Boot Code section protection

Procurement Notes

Verify that the specific ordering suffix matches the required package style and temperature grade. Confirm that the procurement source provides documentation consistent with the preliminary datasheet status. Ensure compatibility with UPDI programming interfaces during integration planning.

Selection Notes

Select this component when a pin-compatible migration within the AVR DU family is required. Consider the 16 KB Flash capacity against application code size requirements. Evaluate the 28-pin SPDIP package suitability for through-hole assembly processes compared to surface-mount alternatives.

Part Context

This part belongs to the AVR® DU family, which offers vertical migration capabilities without code modification across different pin counts and memory sizes. The family integrates advanced analog features and a hardware multiplier. The AVR16DU28 variant specifically provides a balance of I/O count and memory resources for mid-range embedded applications.
