ATTINY25V-15ST

Overview

The ATTINY25V-15ST is an 8-bit AVR microcontroller from Microchip Technology, featuring a V-series speed grade. It integrates 2 KB of In-System Programmable Flash memory, 128 bytes of EEPROM, and 128 bytes of SRAM. The device supports a maximum clock frequency of 15 MHz at operating voltages between 2.7 V and 5.5 V. It utilizes a TSSOP-8 package and operates within an industrial temperature range.

Feature Summary

• AVR enhanced RISC architecture with single-cycle execution capabilities
• In-system programmable non-volatile memory for program and data storage
• Integrated Universal Serial Interface (USI) for communication protocols
• Four-channel 10-bit analog-to-digital converter with differential inputs

Applications

• Battery-powered embedded control systems
• Industrial sensor interfaces
• Consumer electronics logic controllers
• Low-power monitoring devices

Procurement Notes

Verify the specific suffix 'ST' corresponds to the TSSOP-8 package configuration in the official datasheet. Confirm that the 'V' designation aligns with the required 1.8V to 5.5V operating voltage range for your power supply design. Ensure the 15 MHz speed grade meets the timing requirements of your application before finalizing procurement.

Selection Notes

Select this component when a compact 8-pin form factor is required alongside low-voltage operation capabilities. The V-series variant provides flexibility for designs running below 2.7V, unlike standard ATtiny25 models. Consider the integrated ADC and USI features if external peripherals are to be minimized in the system design.

Part Context

This part belongs to the ATtiny25/45/85 family of 8-bit microcontrollers manufactured by Microchip Technology. These devices are based on the AVR core and are designed for high performance with low power consumption. The family shares common architectural features but varies in memory size and package options.

Replacement Considerations

Compatible substitutes include other members of the ATtiny25/45/85 series, such as the ATTINY25-15SU or ATTINY25V-10SSU, provided pin compatibility and speed grades match the design requirements.
