ATTINY84V-10SSU

Overview

The ATTINY84V-10SSU is an 8-bit AVR microcontroller featuring 8KB of in-system programmable Flash memory, 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 1.8V to 5.5V. The device utilizes a 20-pin SOIC package and includes an 8-channel 10-bit ADC.

Feature Summary

• Advanced RISC architecture delivering up to 1 MIPS throughput at 10 MHz
• Non-volatile memory with high endurance for Flash and EEPROM
• Integrated analog-to-digital converter with multiple input channels
• Fully static operation supporting low-power idle and power-down modes

Applications

• Battery-powered sensor nodes
• Simple human-machine interface controllers
• Low-speed serial communication gateways
• Basic logic control in embedded systems

Procurement Notes

Verify the specific suffix 'SSU' against the manufacturer's official datasheet to confirm the package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your target assembly process. Cross-reference the manufacturing date code to verify availability status, as older Atmel-branded parts may have transitioned to Microchip Technology production lines.

Selection Notes

Select this component when a balance of moderate program memory and low power consumption is required. The 10 MHz speed is sufficient for basic control loops but may be insufficient for high-frequency signal processing. Consider the 20-pin SOIC footprint constraints during PCB layout. Evaluate if the 512-byte SRAM limit accommodates your application's variable storage needs without external memory expansion.

Part Context

This part belongs to the ATtiny84 family of 8-bit AVR microcontrollers. It shares architectural similarities with other members like the ATtiny84A but differs in voltage ranges and package options. The 'V' suffix typically indicates a wider operating voltage range or lower power variant compared to standard versions within the same series.

Replacement Considerations

Direct pin-compatible replacements include the ATtiny84A-SSU. Verify electrical characteristics such as maximum clock speed and voltage limits before substitution. Alternative packages like QFN or TQFP require schematic redesign.
