Overview
The AVR16DD32T-E/PT is an 8-bit microcontroller from the AVR DD family, featuring a 16 KB Flash memory, 2 KB SRAM, and 256 bytes of EEPROM. It operates at clock speeds up to 24 MHz within a supply voltage range of 1.8V to 5.5V. The device includes a 12-bit ADC with 7 channels, a 10-bit DAC, two USARTs, SPI, TWI/I2C interfaces, and Multi-Voltage I/O (MVIO). Packaged in TQFP-32, it supports extended temperature operation from -40°C to +125°C.
Feature Summary
- Supports vertical migration without code modification across the AVR DD family due to pin and feature compatibility.
- Features Multi-Voltage I/O (MVIO) on PORT C for flexible interface voltage selection.
- Includes an Event System for CPU-independent inter-peripheral signaling and Configurable Custom Logic (CCL).
Applications
- Industrial control systems requiring multi-voltage I/O flexibility
- Home appliance products needing real-time control capabilities
- IoT devices utilizing low-power architecture and event-driven processing
Procurement Notes
Verify the ordering suffix 'E' confirms the extended temperature range (-40°C to +125°C) and 'T' indicates tape and reel packaging. Confirm the 'PT' suffix corresponds to the TQFP-32 package style. Ensure the component matches the specific 16 KB Flash variant within the AVR DD family rather than higher capacity models.
Selection Notes
Select this model when extended temperature performance is required alongside 16 KB program memory. The TQFP-32 package offers surface mount convenience. Consider the 2 KB SRAM limit for application complexity. Verify that the 7 available ADC channels meet sensor interface requirements.
Part Context
This component belongs to the AVR DD family, which utilizes the AVR CPU with a hardware multiplier. The family provides horizontal and vertical migration paths. The AVR16DD32 variant sits below the 32 KB and 64 KB Flash options while sharing the same 32-pin footprint and peripheral set as larger siblings.
