ATTINY84V-10SSU

Overview

The ATTINY84V-10SSU is an 8-bit AVR microcontroller featuring 8K bytes of in-system programmable Flash, 512 bytes of EEPROM, and 512 bytes of SRAM. It operates within a voltage range of 1.8V to 5.5V with a maximum clock frequency of 10MHz. The device includes twelve programmable I/O lines, a 10-bit ADC with eight single-ended channels, two timer/counters with PWM capabilities, and an on-chip analog comparator. It utilizes a fully static Advanced RISC architecture for efficient processing.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle
• In-system programmable non-volatile memory with high endurance ratings
• Integrated 10-bit analog-to-digital converter with differential channel support
• Multiple low-power sleep modes including power-down and idle

Applications

• Battery-powered sensor nodes requiring low active current
• Industrial control systems operating in industrial temperature ranges
• General-purpose digital logic replacement in embedded designs
• Applications utilizing the debugWIRE interface for development

Procurement Notes

Verify the specific ordering code matches the required speed grade and package type. Confirm that the 'V' suffix indicates the extended voltage range capability. Ensure the 'SSU' designation corresponds to the 14-lead SOIC package variant. Check for any applicable RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when 8KB of program memory is necessary alongside robust analog input capabilities. The V-series variant supports operation down to 1.8V, making it suitable for battery applications where standard ATtiny84 variants may not suffice at lower voltages. Consider the 10MHz speed limit when designing timing-critical loops.

Part Context

This part belongs to the ATtiny24/44/84 family of 8-bit AVR microcontrollers manufactured by Microchip Technology. The family shares a common core architecture but differs in memory sizes and pin counts. The ATTINY84V-10SSU specifically provides the highest memory capacity within the 14-pin package options of this series.

Replacement Considerations

ATtiny84-20SSU offers similar functionality but requires a minimum supply voltage of 2.7V instead of 1.8V.
