ATTINY85V-15ST

Overview

The ATTINY85V-15ST is an 8-bit AVR microcontroller from Microchip Technology, housed in a TSSOP-8 surface-mount package. It features 8 kB of in-system programmable Flash memory, 512 bytes of SRAM, and 512 bytes of EEPROM. The device supports a maximum clock frequency of 15 MHz and operates within a supply voltage range of 1.8 V to 5.5 V. It includes one 10-bit ADC with four channels, a single 8-bit timer/counter with PWM capabilities, and a Universal Serial Interface (USI) for SPI or I2C communication. The component is rated for industrial temperatures between -40°C and +85°C.

Feature Summary

• Integrates picoPower technology to enable ultra-low power consumption across active and sleep modes.
• Provides flexible non-volatile storage with high endurance for both program flash and data EEPROM.
• Supports in-system programming via SPI interface for simplified firmware updates.

Applications

• Battery-powered sensor nodes requiring extended operational life
• Compact embedded control systems with limited board space
• Low-cost consumer electronics utilizing minimal I/O resources

Procurement Notes

Verify the specific suffix 'ST' against official Microchip documentation to confirm the exact tape-and-reel packaging configuration and temperature grade. Ensure the ordered part matches the required voltage range and operating temperature specifications for your target application environment before finalizing procurement.

Selection Notes

Select this variant when a surface-mount TSSOP-8 footprint is required alongside a 15 MHz processing speed. It is suitable for designs needing 8 kB of code space and low-voltage operation down to 1.8 V. Consider alternative packages if through-hole mounting or higher pin counts are necessary for the system architecture.

Part Context

This component belongs to the ATtiny85 family of 8-bit AVR microcontrollers. It shares core architectural similarities with other variants like the ATTINY85V-10SU but offers a higher maximum clock frequency of 15 MHz compared to the 10 MHz limit of some lower-speed counterparts. The 'V' suffix indicates extended voltage support starting at 1.8 V.

Replacement Considerations

Direct substitutes include ATTINY85V-10SU and ATTINY85V-10SSU for similar functionality with slightly reduced clock speeds. For higher performance requirements, consider the ATTINY85-20PU or ATTINY85-20MU variants which support up to 20 MHz operation.
