ATTINY817-MNR

Overview

The ATTINY817-MNR is an 8-bit microcontroller from Microchip Technology's tinyAVR 1 series, featuring a 20 MHz AVR core. It integrates 8 KB of Flash memory, 512 bytes of SRAM, and 128 bytes of EEPROM within a 24-VQFN package. The device supports a supply voltage range of 1.8 V to 5.5 V and operates across an industrial temperature range of -40°C to +125°C. Key peripherals include a 10-bit ADC with multiple channels, an 8-bit DAC, and standard communication interfaces such as I2C, SPI, and USART.

Feature Summary

• Integrates a high-performance 8-bit AVR core capable of executing instructions in a single clock cycle at speeds up to 20 MHz.
• Includes advanced analog peripherals such as a multi-channel 10-bit Analog-to-Digital Converter and an 8-bit Digital-to-Analog Converter for signal processing.
• Supports flexible communication protocols including I2C, SPI, and USART for reliable data exchange with external components.

Applications

• Industrial control systems requiring robust performance in harsh environments
• Battery-powered consumer devices utilizing low-voltage operation
• Smart home appliances needing integrated sensor interfacing

Procurement Notes

Verify the specific suffix 'MNR' against official Microchip documentation to confirm tape-and-reel packaging and exact temperature grade. Ensure compatibility with existing PCB footprints for the 24-VQFN package. Cross-reference datasheet revisions to confirm pinout consistency before finalizing procurement orders.

Selection Notes

Select this component when a balance of moderate program memory and rich analog features is required. It is suitable for applications needing precise analog measurements via the 10-bit ADC while maintaining low power consumption. Consider the 24-pin form factor for space-constrained designs that still require multiple I/O lines and communication interfaces.

Part Context

This part belongs to the tinyAVR 1 family, designed for cost-sensitive embedded applications. It shares architectural similarities with other members like the ATtiny816 and ATtiny814 but offers specific memory and package configurations tailored for compact industrial and consumer electronics.

Replacement Considerations

Check for direct pin-compatible alternatives within the same tinyAVR 1 series, such as the ATtiny816 or ATtiny814, ensuring memory sizes meet application requirements. Verify that any substitute maintains the same 24-VQFN package and operating voltage specifications.
