ATTINY25V-10PU

Overview

The ATTINY25V-10PU is an 8-bit AVR microcontroller manufactured by Microchip Technology, housed in an 8-pin PDIP package. It features a high-performance AVR RISC core operating at up to 10 MHz with a supply voltage range of 1.8V to 5.5V. The device includes 2KB of In-System Programmable Flash memory, 128 bytes of EEPROM, and 128 bytes of SRAM. Key peripherals include a 4-channel 10-bit ADC, two PWM channels, a Universal Serial Interface (USI), and a programmable Watchdog Timer.

Feature Summary

• AVR enhanced RISC architecture executing most instructions in a single clock cycle for efficient processing.
• Non-volatile memory with 10,000 write/erase cycles for Flash and 100,000 cycles for EEPROM.
• Integrated USI supporting SPI, TWI, and general shift register operations.
• Four software-selectable power-saving modes including Idle, ADC Noise Reduction, and Power-down.

Applications

• Battery-powered consumer electronics requiring low active and standby current consumption.
• Industrial control systems utilizing the industrial temperature range and robust I/O capabilities.
• Sensor interface applications leveraging the internal 10-bit ADC and analog comparator.
• Simple communication nodes using the USI peripheral for SPI or I2C protocols.

Procurement Notes

Verify that the specific ordering code matches the required speed grade and package type. Confirm RoHS compliance status as per the manufacturer's latest documentation. Ensure the procurement channel provides genuine components from authorized distributors to avoid counterfeit devices. Check for any specific handling requirements related to electrostatic discharge during storage and assembly.

Selection Notes

Select this component when a balance of moderate program memory and low power consumption is required. The V suffix indicates operation down to 1.8V, suitable for battery applications. Consider the PDIP package only if through-hole mounting is necessary for mechanical stability or prototyping. Evaluate the 10MHz maximum frequency against system timing requirements to ensure adequate processing headroom.

Part Context

This device belongs to the ATtiny family of 8-bit AVR microcontrollers, designed for cost-sensitive embedded applications. It shares architectural similarities with the ATtiny45 and ATtiny85, differing primarily in memory sizes. The series is characterized by its picoPower technology and compatibility with standard AVR development tools.
