ATTINY84V-10PU

Overview

The ATTINY84V-10PU is an 8-bit AVR microcontroller featuring a high-performance, low-power RISC architecture with 120 instructions, most executing in a single clock cycle. It includes 8 KB of in-system programmable Flash, 512 bytes of EEPROM, and 512 bytes of SRAM. The device operates at voltages from 1.8 V to 5.5 V with a maximum frequency of 10 MHz. Key peripherals include two 8-bit timers/counters with PWM channels, an 8-channel 10-bit ADC, and a universal serial interface. It offers 12 I/O lines in a 14-pin PDIP package.

Feature Summary

• Advanced RISC architecture enabling efficient single-cycle instruction execution
• Non-volatile memory systems with high endurance for Flash and EEPROM
• Integrated analog-to-digital conversion with multiple channel options
• Comprehensive peripheral set including timers, counters, and serial interfaces

Applications

• Battery-powered embedded systems requiring low voltage operation
• Sensor interface circuits utilizing the internal ADC capabilities
• Simple control loops managed by timer and PWM outputs
• Communication nodes using the universal serial interface

Procurement Notes

Verify the specific suffix 'PU' confirms the 14-pin PDIP package and through-hole mounting style. Confirm the 'V' designation indicates the extended 1.8 V minimum operating voltage range. Ensure the '-10' speed grade matches the required 10 MHz maximum clock frequency for the target application voltage. Check current lifecycle status as older variants may have limited availability.

Selection Notes

Select this component when a robust 8-bit AVR core is needed with moderate program memory capacity. The 1.8 V operating range makes it suitable for battery applications where power efficiency is critical. Consider the 14-pin constraint if pin count requirements are modest. Evaluate the trade-off between the PDIP package's ease of prototyping and the available surface-mount alternatives like SSOP or QFN for final production designs.

Part Context

This part belongs to the ATtiny family of 8-bit microcontrollers produced by Microchip Technology (formerly Atmel). It shares the core AVR architecture with other members like the ATtiny24/44/84 series, differing primarily in memory sizes and pin counts. The ATTINY84V-10PU represents the higher memory variant within the 14-pin package lineup, offering enhanced storage compared to its smaller counterparts while maintaining the same physical footprint.

Replacement Considerations

Direct substitutes include the ATTINY84-10PU for standard voltage operation or ATTINY84V-10SSU for surface mount packaging. Verify pin compatibility and memory specifications before swapping. Other ATtiny series members may require schematic modifications due to differing pinouts or peripheral configurations.
