AVR16DD14T-I/SL

Overview

The AVR16DD14T-I/SL is an 8-bit microcontroller from the AVR DD Family, featuring a 16 KB Flash program memory and 2 KB SRAM. It operates at a maximum clock frequency of 24 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes a 12-bit ADC with 7 channels, a 10-bit DAC, two USARTs, SPI, and TWI interfaces. It utilizes a SOIC-14 package and supports an industrial temperature range of -40°C to +85°C.

Feature Summary

• Features Multi-Voltage I/O (MVIO) on PORTC for flexible voltage level interfacing.
• Includes a Zero-Cross Detector (ZCD) for AC mains detection applications.
• Supports automated Cyclic Redundancy Check (CRC) scanning for Flash memory integrity verification.

Applications

• General-purpose embedded control systems
• AC mains sensing and zero-crossing detection circuits
• Low-voltage sensor interface designs

Procurement Notes

Verify the ordering suffix 'I' confirms the industrial temperature range (-40°C to +85°C). Confirm the 'SL' suffix corresponds to the SOIC-14 package style. Ensure the 'T' indicates tape and reel packaging if required for assembly. Cross-reference the specific datasheet revision DS40002315C for accurate electrical characteristics.

Selection Notes

Select this component when 16 KB of Flash and 2 KB of RAM are sufficient for the application logic. Choose the AVR16DD14 over higher-memory variants to optimize cost and pin count. Consider the MVIO capability if interfacing with mixed-voltage peripherals without external level shifters.

Part Context

This part belongs to the AVR DD Family, which offers vertical migration compatibility within the series. It shares architectural features with the AVR32DD14 and AVR64DD14, differing primarily in memory size. The family emphasizes low-power operation and advanced digital peripherals like the Event System and Configurable Custom Logic.

Replacement Considerations

AVR16DD14T-E/SL provides the same specifications but with an extended temperature range (-40°C to +125°C).
