AVR32DD14-I/SL

Overview

The AVR32DD14-I/SL is an 8-bit microcontroller from the AVR DD family, featuring a 32 KB Flash memory and 4 KB SRAM. It utilizes an AVR CPU with a hardware multiplier, operating at clock speeds up to 24 MHz across a supply voltage range of 1.8V to 5.5V. The device includes 14 pins in an SOIC package and supports industrial temperatures (-40°C to +85°C). Key peripherals include a 12-bit differential ADC, 10-bit DAC, ZCD, two USARTs, SPI, TWI/I2C, and four CCL LUTs.

Feature Summary

• Multi-Voltage I/O (MVIO) capability on PORTC for level shifting without external converters
• Configurable Custom Logic (CCL) with four Look-up Tables for custom digital logic implementation
• Event System (EVSYS) enabling CPU-independent inter-peripheral signaling
• Integrated Zero-Cross Detector (ZCD) and Analog Comparator for power control applications

Applications

• Industrial control systems requiring multi-voltage domain communication
• Smart home appliances with AC mains monitoring via ZCD
• IoT terminal nodes utilizing low-power architecture
• Sensor interfaces requiring precise analog signal conditioning

Procurement Notes

Verify the specific ordering suffix 'SL' corresponds to the SOIC-14 package style and Industrial temperature grade as defined in the datasheet nomenclature. Confirm that the 'I' suffix indicates the -40°C to +85°C operating range. Ensure compatibility with existing design footprints for SOIC packages before procurement.

Selection Notes

Select this component when 32 KB of program memory and 4 KB of RAM are sufficient for the application logic. Choose the AVR32DD14 over larger variants if pin count reduction is required while maintaining feature compatibility within the AVR DD family. Consider the MVIO feature if interfacing with 3.3V or 5V peripherals directly from a 1.8V core.

Part Context

This part belongs to the AVR DD family, which offers vertical migration compatibility with AVR16DD and AVR64DD series devices. The 14-pin variant provides a reduced footprint compared to the 20, 28, and 32-pin options while retaining core architectural features like the single-cycle I/O access and hardware multiplier.

Replacement Considerations
