AVR16DD14-I/SL

Overview

The AVR16DD14-I/SL is an 8-bit microcontroller from the AVR DD family, featuring a hardware multiplier CPU running at up to 24 MHz. It includes 16 KB of Flash memory, 2 KB of SRAM, and 256 bytes of EEPROM. The device provides 10 general-purpose I/O pins in a 14-pin SOIC package. Key peripherals include a 12-bit ADC with seven channels, a 10-bit DAC, two USARTs, SPI, TWI/I2C, and a Zero-Cross Detector. It supports Multi-Voltage I/O (MVIO) on PORT C and operates within a supply voltage range of 1.8 V to 5.5 V.

Feature Summary

• Multi-Voltage I/O (MVIO) capability enables direct bidirectional communication between different power domains without external level shifters.
• Integrated intelligent analog features including a 12-bit differential ADC, 10-bit DAC, Analog Comparator, and Zero-Cross Detector for precise signal processing.
• Configurable Custom Logic (CCL) allows complex digital logic implementation independent of the CPU core.
• Event System facilitates low-latency, CPU-independent signaling between peripherals.

Applications

• Industrial control systems requiring real-time response
• Smart home appliances with multi-voltage domain interfaces
• IoT devices utilizing low-power sleep modes
• Motor control applications leveraging PWM and ZCD

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 as specified in the datasheet. Ensure compatibility with existing design footprints by checking pinout definitions against the specific package variant.

Selection Notes

Select this component when a balance of moderate memory size and rich peripheral set is required in a compact 14-pin form factor. Consider the AVR16DD14 over larger pin-count variants if board space is constrained but MVIO and advanced analog features remain necessary for system integration.

Part Context

This part belongs to the AVR DD family, which emphasizes vertical migration capabilities across pin counts without code modification. It shares architectural similarities with the AVR32DD14 and AVR64DD14, differing primarily in memory capacity while maintaining identical peripheral configurations and pinouts for the 14-pin variant.

Replacement Considerations

AVR16DD14T-E/SL: Offers extended temperature range (+125°C max) instead of industrial (-40°C to +85°C). AVR32DD14-I/SL: Provides double the Flash and SRAM memory with identical pinout and peripherals.

FAQ

Does the AVR16DD14 support simultaneous host and client operation on its I2C interface?

Yes, the TWI/I2C peripheral supports dual address match and can operate simultaneously as both host and client on different pins.

What is the maximum operating frequency of the internal oscillator?

The high-precision internal high-frequency oscillator (OSCHF) supports selectable frequencies up to 24 MHz.

Can the device communicate directly with 3.3V logic if powered by 5V?

Yes, the Multi-Voltage I/O (MVIO) feature on PORT C allows for true level-shifted bidirectional communication with devices operating at different supply voltages.
