AVR16DU in AVR DA/DB/DD/DU Family
The AVR16DU family by Microchip Technology represents a modern expansion of the 8-bit AVR architecture, integrating Full-Speed USB 2.0 connectivity without the need for an external crystal. Built on the high-performance AVR core with Core Independent Peripherals, these microcontrollers are designed to minimize CPU overhead in data-intensive tasks. They are primarily utilized in cost-sensitive industrial and consumer applications where reliable USB communication, robust noise immunity, and low power consumption are critical system requirements.
Variants in This Sub-Family
| Part Number | Difference | Stock |
|---|---|---|
| AVR16DU32-I/PT (Microchip Technology) | 32-I/PT | 650 |
| AVR16DU28-I/STX (Microchip Technology) | TX | 637 |
| AVR16DU20-I/REB (Microchip Technology) | 0-I/REB | 436 |
| AVR16DU14-I/SL (Microchip Technology) | 14-I/SL | 436 |
| AVR16DU32-I/RXB (Microchip Technology) | 32-I/RXB | 445 |
The AVR16DU sub-family members primarily vary by their physical packaging and pin counts, ranging from 14-pin SOIC and 20-pin VQFN to 32-pin TQFP options. While all variants feature 16KB of Flash and 2KB of SRAM, the available number of GPIO pins and multiplexed peripheral channels scales with the package size. Thermal performance and space constraints often dictate the specific selection of the SS, STX, or RXB suffix variants.
