ATTINY84V-10MU

Overview

The ATTINY84V-10MU is an 8-bit AVR microcontroller featuring 8 KB of in-system programmable Flash, 512 bytes of EEPROM, and 512 bytes of SRAM. It operates at a maximum clock frequency of 10 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes 12 general-purpose I/O lines, an 8-channel 10-bit ADC, two timers/counters, and a Universal Serial Interface. It is housed in a 20-pad QFN/MLF package (20M1) and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for high throughput efficiency.
• Integrated non-volatile memories including Flash, EEPROM, and SRAM with data retention capabilities.
• On-chip analog peripherals comprising a 10-bit ADC with differential channels and an analog comparator.
• Comprehensive power management with multiple software-selectable sleep modes to minimize consumption.

Applications

• Low-power embedded control systems requiring efficient processing.
• Battery-operated devices utilizing the wide operating voltage range.
• Sensor interfaces leveraging the integrated ADC and analog comparator.
• Industrial applications within the specified temperature range.

Procurement Notes

Verify the specific ordering suffix 'MU' corresponds to the matte tin finish and QFN package configuration as defined in the manufacturer's documentation. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure the design accommodates the exposed pad grounding requirement for the QFN package to maintain thermal and electrical integrity.

Selection Notes

Select this variant when a 1.8 V minimum operating voltage is required compared to standard versions. The 10 MHz speed grade suits applications needing moderate processing speeds without excessive power draw. Consider the 20-pin QFN package for space-constrained PCB layouts. Verify compatibility with existing debugWIRE or ISP programming interfaces during development.

Part Context

This component belongs to the ATtiny24/44/84 family of 8-bit AVR microcontrollers. It shares the same core architecture and peripheral set as other members in the series, differentiated primarily by memory size and package options. The 'V' designation indicates support for lower supply voltages starting at 1.8 V.

FAQ

What is the function of the bottom pad on the QFN package?

The bottom pad must be soldered to ground to ensure proper thermal dissipation and electrical connection.

How does the device handle reset conditions?

A low level on the RESET pin generates a reset if held longer than the minimum pulse length, unless the RSTDISBL fuse is programmed.

What are the available power saving modes?

The device supports Idle, ADC Noise Reduction, Standby, and Power-Down modes to optimize power consumption based on application needs.
