ATTINY25V-10PI

Overview

The ATTINY25V-10PI is an 8-bit AVR microcontroller manufactured by Atmel, now part of Microchip Technology. It features 2KB of in-system programmable Flash memory for program storage and 128 bytes of SRAM for data handling. The device includes 128 bytes of EEPROM for non-volatile data retention. It operates with a maximum clock frequency of 10 MHz and supports a supply voltage range that includes operation at 1.8 V minimum at 4 MHz. The component is housed in a 28-pin PDIP package.

Feature Summary

• Incorporates the high-performance, low-power AVR 8-bit RISC architecture
• Provides in-system programmable Flash memory for flexible code updates
• Integrates dedicated analog-to-digital converter capabilities
• Supports multiple power-saving operating modes to extend battery life

Applications

• Battery-powered consumer electronics requiring low standby current
• Industrial control systems utilizing I/O expansion
• Smart home devices needing reliable embedded processing
• Automotive sensor interfaces demanding robust operation

Procurement Notes

Verify the manufacturer designation as Atmel or Microchip depending on the production era. Confirm the package type is PDIP-28 and the speed grade is 10 MHz. Ensure the suffix 'V' indicates the extended voltage range compliance. Check RoHS status as early Atmel versions may not be compliant. Request the specific datasheet revision to confirm pinout and electrical characteristics.

Selection Notes

Select this component when an 8-bit AVR core is required with moderate program memory. Consider the PDIP-28 package for through-hole assembly needs. Evaluate the 10 MHz performance against system timing requirements. Compare the 128-byte EEPROM size with application data persistence needs. Verify voltage compatibility with the target circuit's power supply rails.

Part Context

This microcontroller belongs to the ATtiny family of 8-bit AVR processors. It shares architectural similarities with other ATtiny devices but offers specific memory configurations. The ATTINY25 variant provides a balance of processing power and peripheral integration suitable for cost-sensitive applications. It represents a standard solution for simple control tasks within the AVR ecosystem.

Replacement Considerations

Direct substitutes include the ATTINY25-10PU for plastic DIP packages or ATTINY25V-10MU for QFN packaging. Cross-reference with ATTINY26V-10PI if additional I/O lines are necessary. Ensure pin compatibility when replacing with higher-density variants like the ATTINY45 series.
