AVR64DD14-E/SL

Overview

The AVR64DD14-E/SL is an 8-bit microcontroller from the AVR DD family, featuring a hardware multiplier CPU running at up to 24 MHz. It includes 64 KB of in-system self-programmable Flash memory, 8 KB of SRAM, and 256 bytes of EEPROM. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports extended temperature ranges. Key peripherals include a 12-bit ADC with 13 channels, a 10-bit DAC, two USARTs, SPI, TWI/I2C, and a configurable custom logic block.

Feature Summary

• Features Multi-Voltage I/O (MVIO) on Port C for direct communication across different power domains without external level shifters.
• Includes an Event System (EVSYS) for CPU-independent inter-peripheral signaling to reduce system latency.
• Supports automated CRC scanning of Flash memory to enhance data integrity and security.
• Integrates intelligent analog peripherals including a zero-cross detector and programmable look-up tables.

Applications

• Industrial control systems requiring real-time processing and noise immunity.
• Smart home appliances utilizing multi-voltage domain interfaces.
• Automotive applications meeting functional safety standards.
• IoT devices requiring low-power operation and efficient peripheral management.

Procurement Notes

Verify the specific package style and carrier type associated with the ordering suffix to ensure compatibility with assembly requirements. Confirm that the extended temperature grade matches the operational environment specifications. Cross-reference the part number against the latest Microchip documentation to validate current production status and availability constraints before finalizing procurement plans.

Selection Notes

Select this component when 64 KB of program memory and 8 KB of RAM are required within a 14-pin footprint. The extended temperature rating makes it suitable for harsh environments where industrial-grade parts may be insufficient. Ensure the design leverages the MVIO feature if interfacing with multiple voltage rails, as this simplifies board layout by eliminating external translation components.

Part Context

This device belongs to the AVR DD family, which emphasizes vertical migration capabilities. Devices within this family share pin and feature compatibility, allowing designers to scale memory and peripheral counts without modifying existing code. The AVR64DD14 represents the 14-pin variant with the highest memory configuration in its pin count class.
