ATTINY85V-10SUR

Overview

The ATTINY85V-10SUR 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 supply voltage range of 1.8V to 5.5V and supports clock frequencies up to 10MHz at the lower voltage limit. The device includes a 10-bit ADC with four single-ended channels and two differential pairs, six programmable I/O lines, and multiple timer/counters. It is housed in an 8-pin SOIC package.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle
• In-system programmable non-volatile memory for program and data storage
• Integrated Universal Serial Interface (USI) for communication protocols
• Multiple low-power operating modes including Idle and Power-down

Applications

• Battery-powered embedded systems requiring low power consumption
• Simple sensor interface applications utilizing the on-chip ADC
• Basic serial communication tasks via the USI peripheral
• General-purpose control logic in compact surface-mount designs

Procurement Notes

Verify that the specific ordering suffix matches the required tape and reel packaging configuration. Confirm the speed grade corresponds to the intended operating frequency and voltage conditions. Ensure the industrial temperature range aligns with the environmental requirements of the target application before finalizing procurement orders.

Selection Notes

Select this component when 8KB of program memory is necessary for complex firmware implementations. Choose this variant over higher-speed models if operation at 1.8V is required while maintaining 10MHz performance. Consider the SOIC-8 package dimensions for PCB layout constraints compared to QFN or TSSOP alternatives available in the same family.

Part Context

This part belongs to the ATtiny85 family of 8-bit AVR microcontrollers manufactured by Microchip Technology. It shares architectural similarities with the ATtiny25 and ATtiny45 but offers increased memory capacity. The 'V' suffix indicates support for extended low-voltage operation down to 1.8V, distinguishing it from standard variants limited to 2.7V minimum.

Replacement Considerations

ATtiny85V-10SU serves as a tube-packaged alternative within the same electrical specification family.
