Overview
The AVR16DD32T-I/RXB 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 with a supply voltage range of 1.8V to 5.5V. The device is housed in a 32-pin VQFN package (RXB) and supports industrial temperature ranges (-40°C to +85°C). Key peripherals include a 12-bit ADC with 23 channels, a 10-bit DAC, two USARTs, SPI, TWI/I2C, and multiple timer/counters.
Feature Summary
- Features a flexible low-power architecture with intelligent analog features and advanced digital peripherals.
- Supports vertical migration without code modification due to full pin and feature compatibility within the family.
- Includes Multi-Voltage I/O (MVIO) on Port C for selectable input voltage thresholds.
- Integrates an Event System for CPU-independent inter-peripheral signaling.
Applications
- Industrial control systems requiring robust peripheral integration
- Smart energy metering applications utilizing high-precision ADCs
- Consumer appliances needing low-power operation and multi-voltage I/O
- Automotive sensor interfaces compatible with LIN and RS-485 protocols
Procurement Notes
Verify the specific ordering suffix RXB confirms the 32-pin VQFN package and T indicates Tape & Reel packaging. Ensure the 'I' suffix matches the required industrial temperature range of -40°C to +85°C. Cross-reference the datasheet DS40002315 for exact pinout and electrical characteristics before finalizing procurement specifications.
Selection Notes
Select this component when 16 KB of program memory and 2 KB of RAM are sufficient for the application logic. Consider the 23-channel 12-bit ADC if extensive analog signal acquisition is needed. Verify that the 32-pin VQFN footprint fits the PCB design constraints and that the 24 MHz maximum frequency meets timing requirements.
Part Context
This part belongs to the AVR DD Family, which utilizes the latest Microchip technologies for flexible and low-power architectures. It shares architectural similarities with other devices in the series, allowing for horizontal migration to reduce pin counts or vertical migration to increase memory size without code changes.
Replacement Considerations
AVR16DD32T-E/RXB offers extended temperature range capabilities. AVR32DD32T-I/RXB provides increased memory resources while maintaining pin compatibility. AVR64DD32T-I/RXB offers higher performance and larger memory capacity for more complex applications.
