• Non-volatile memory with high endurance ratings for program flash and EEPROM data retention.
• Integrated analog-to-digital converter supporting differential channel pairs with programmable gain.
• Supports multiple low-power operating modes including Idle, Power-down, and ADC Noise Reduction.

Applications

• Battery-powered embedded systems requiring extended operational life
• Temperature measurement applications utilizing internal sensors
• General-purpose digital control logic in compact designs

Procurement Notes

Verify the specific ordering code against official Microchip documentation to ensure correct package type and speed grade. Confirm RoHS compliance status and lead finish specifications prior to procurement. Check for any applicable errata regarding EEPROM read operations at low voltages.

Selection Notes

Select this component when a balance of processing speed and low power consumption is required within a small footprint. Ensure the application voltage remains within the specified 1.8 V to 5.5 V range for optimal performance at the 10 MHz speed grade.

Part Context

This part belongs to the ATtiny45/V family, which shares core architectural features with the ATtiny25 and ATtiny85 variants. The primary distinction lies in the memory capacity, with the ATtiny45 offering intermediate storage levels compared to its siblings.

FAQ

What is the function of the 'V' suffix in the model number?

The 'V' indicates that the device supports a lower minimum supply voltage of 1.8 V, enabling operation down to this threshold at reduced clock frequencies.

How does the TSSOP package differ from other options?

The TSSOP package (indicated by 'X') is exclusively available for the ATtiny45 variant, providing a thin-shrink outline form factor suitable for space-constrained PCB layouts.
