ATTINY84V-10SSUR

Overview

The ATTINY84V-10SSUR 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 at speeds up to 10 MHz with a supply voltage range of 1.8V to 5.5V. The device includes a 10-bit ADC with 8 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
• Integrated 10-bit ADC with differential channel pairs and programmable gain
• Dual timer/counters supporting multiple PWM output channels
• On-chip debugWIRE interface for in-system programming and debugging

Applications

• Battery-powered sensor nodes requiring low active current consumption
• Industrial control systems operating within the industrial temperature range
• General-purpose I/O expansion modules utilizing pin change interrupts
• Signal conditioning circuits leveraging the internal analog comparator

Procurement Notes

Verify that the specific ordering suffix matches the required package type and tape & reel configuration. Confirm the speed grade corresponds to the intended system clock frequency and operating voltage. Ensure the component meets RoHS compliance standards if required by the manufacturing process. Cross-reference the datasheet revision history for any relevant errata affecting EEPROM access or lock bit modes.

Selection Notes

Select this variant when 8K Flash memory is necessary for complex application logic. Choose the V-speed grade for designs requiring operation down to 1.8V. Consider the SOIC package dimensions for PCB layout constraints. Evaluate the power-down mode current specifications against strict battery life requirements.

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 the ATtiny24V and ATtiny44V, differentiated primarily by its non-volatile memory capacity. The family supports unified development tools and software libraries across all memory variants.

Replacement Considerations

ATtiny84-20SSUR provides equivalent functionality with a higher maximum speed rating of 20 MHz but requires a minimum supply voltage of 2.7V.
