ATTINY85V-10PU

Overview

The ATTINY85V-10PU is an 8-bit AVR microcontroller featuring 8 kB of In-System Programmable Flash, 512 bytes of EEPROM, and 512 bytes of SRAM. It operates within a voltage range of 1.8 V to 5.5 V at frequencies up to 10 MHz. The device includes six programmable I/O lines, a 4-channel 10-bit ADC, two PWM channels, and a Universal Serial Interface (USI). It supports debugWIRE on-chip debugging and utilizes a fully static RISC architecture for efficient power management.

Feature Summary

• Advanced RISC architecture with most instructions executing in a single clock cycle
• In-system programmable non-volatile memory with high endurance ratings
• Integrated analog-to-digital converter with differential channel pairs and programmable gain
• Multiple software-selectable low-power operating modes including idle and power-down

Applications

• Battery-powered sensor nodes requiring ultra-low standby current
• Simple serial communication interfaces using the Universal Serial Interface
• Basic motor control applications utilizing hardware PWM outputs
• Temperature monitoring systems leveraging internal ADC and comparator features

Procurement Notes

Verify that the specific ordering code matches the required speed grade and package type. Confirm the presence of the 'V' suffix indicates the extended low-voltage operation capability down to 1.8 V. Ensure the 'PU' designation corresponds to the 8-lead PDIP package format. Check for RoHS compliance documentation if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when project constraints demand minimal pin count alongside sufficient program storage for complex logic. The low-voltage variant is suitable for direct interfacing with 1.8 V logic domains without level shifting. Consider the PDIP package only if prototyping or through-hole assembly is strictly required rather than surface mount solutions.

Part Context

This device belongs to the ATtiny family of 8-bit microcontrollers manufactured by Microchip Technology. It shares the core architecture with the ATtiny25 and ATtiny45 variants, differing primarily in memory capacity. The series is designed for cost-sensitive embedded applications where processing efficiency and power consumption are critical design factors.

Replacement Considerations

ATtiny85-10PU serves as the standard high-speed equivalent without low-voltage support. ATtiny45V-10PU offers identical functionality but with reduced memory resources. Verify pin compatibility and fuse settings when migrating between these specific members of the ATtiny85/45/25 family.
