Overview
The AVR64DA64-E/MR is an 8-bit microcontroller from the AVR DA family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 64 KB of Flash memory, 8 KB of SRAM, and 512 B of EEPROM. The device provides up to 55 programmable I/O pins and operates within an extended temperature range of -40°C to +125°C. Key peripherals include six USARTs, two SPI interfaces, two TWI/I2C modules, a 12-bit differential ADC with 22 channels, three analog comparators, one DAC, and a Peripheral Touch Controller.
Feature Summary
- Supports Program and Debug Interface Disable (PDID) for secure firmware upgrades and authentication
- Features an Event System for CPU-independent inter-peripheral signaling
- Includes Configurable Custom Logic (CCL) with multiple programmable Look-up Tables
- Provides a Peripheral Touch Controller (PTC) with Driven Shield+ technology
Applications
- Industrial control systems requiring extended temperature operation
- Smart home appliances with capacitive touch interfaces
- IoT devices needing secure over-the-air updates
- Power control applications utilizing Timer/Counter type D
Procurement Notes
Verify that the ordering suffix 'E' confirms the extended temperature rating (-40°C to +125°C) and 'MR' specifies the VQFN-64 package. Ensure the specific revision of datasheet DS40002233 matches the silicon version required for your design. Confirm availability of PDID-enabled variants if security features are mandatory.
Selection Notes
Select this model when vertical migration from smaller pin counts is needed without code modification. Choose the extended temperature grade for harsh environments. Verify that the 22-channel ADC and five TCB timers meet system requirements. Consider the VQFN-64 package dimensions for PCB layout constraints.
Part Context
This component belongs to the AVR DA(S) family, which offers horizontal and vertical migration capabilities. It shares architectural similarities with AVR64DA28, AVR64DA32, and AVR64DA48 models, differing primarily in pin count and peripheral availability. The family utilizes the latest Microchip technologies for low-power operation and intelligent analog features.
Replacement Considerations
AVR64DA64-I/MR serves as the industrial temperature variant. AVR128DA64-S/MR provides increased Flash memory and PDID support.
