AVR32DD14T-E/SL

Overview

The AVR32DD14T-E/SL is an 8-bit microcontroller from the AVR DD Family, featuring a 14-pin SOIC package. It includes 32 KB of Flash memory, 4 KB of 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. Key peripherals include a 12-bit ADC with 13 channels, a 10-bit DAC, two USARTs, SPI, TWI/I2C, and Multi-Voltage I/O (MVIO). It supports extended temperature operation from -40°C to +125°C.

Feature Summary

• Multi-Voltage I/O (MVIO) capability on PORT C for flexible interfacing
• Integrated 12-bit differential Analog-to-Digital Converter (ADC)
• Configurable Custom Logic (CCL) with Look-up Tables
• Event System for inter-peripheral signaling

Applications

• Industrial control systems
• Home appliance controllers
• IoT sensor nodes
• Automotive electronics

Procurement Notes

Verify the specific ordering suffix 'T' indicates Tape & Reel packaging and 'E' denotes Extended temperature range (-40°C to +125°C). Confirm the 'SL' suffix corresponds to the SOIC-14 package style. Ensure compatibility with the AVR DD Family pinout and peripheral configuration before finalizing procurement orders.

Selection Notes

Select this model for applications requiring 32 KB of program memory and 14 pins. It is suitable for designs needing multi-voltage I/O support and high-temperature reliability. Compare against AVR32DD20 or AVR32DD28 if additional I/O or ADC channels are required.

Part Context

This component belongs to the AVR DD Family, which offers vertical migration without code modification within the series. It shares architectural features like the AVR CPU with hardware multiplier and unified UPDI interface with larger pin-count variants in the same family.

Replacement Considerations

AVR32DD14-I/SL (Industrial temperature range), AVR64DD14T-E/SL (64 KB Flash variant), AVR16DD14T-E/SL (16 KB Flash variant).
