ATTINY44V-10PU

Overview

The Atmel ATTINY44V-10PU is an 8-bit microcontroller based on the AVR RISC architecture, housed in a 14-pin PDIP package. It features 4 kB of in-system programmable Flash memory and 256 bytes of SRAM. The device supports a maximum clock frequency of 10 MHz and operates within a supply voltage range of 1.8 V to 5.5 V. It includes one 8-channel 10-bit analog-to-digital converter (ADC) and one PWM unit with four channels. The component functions across a temperature range of -40 °C to +85 °C.

Feature Summary

• AVR high-performance 8-bit RISC core executing most instructions in a single clock cycle
• Non-volatile program and data memories with high endurance specifications
• Integrated 8-channel 10-bit analog-to-digital conversion capability
• Fully static operation allowing flexible clock speed selection

Applications

• Battery-powered embedded systems requiring low power consumption
• Industrial control applications operating within extended temperature ranges
• Consumer electronics utilizing the 14-pin through-hole form factor
• General-purpose I/O expansion and monitoring tasks

Procurement Notes

Verify the manufacturer designation, as Atmel was acquired by Microchip Technology. Confirm the specific suffix 'V' indicates the wide voltage operating range and '10' denotes the 10 MHz speed grade. Ensure the 'PU' suffix corresponds to the 14-pin PDIP package type required for your assembly process. Check current product status, as legacy AVR devices may have varying availability or end-of-life notices.

Selection Notes

Select this component when a 14-pin through-hole package is necessary for prototyping or specific board layouts. Choose this model over surface mount variants if manual soldering or rework capabilities are limited. Consider the 4 kB Flash capacity sufficient for moderate firmware complexity. Evaluate the 1.8 V to 5.5 V operating range against your system's power supply constraints before finalizing the design.

Part Context

The ATTINY44V-10PU belongs to the ATtiny family of 8-bit AVR microcontrollers, originally developed by Atmel Corporation. Following Microchip Technology's acquisition of Atmel in 2016, these products are now managed under the Microchip portfolio. This specific part represents a legacy device offering a balance of processing power and pin count suitable for resource-constrained embedded applications.

Replacement Considerations

Direct pin-compatible replacements within the same package include other ATtiny44 variants with different speed or voltage ratings, such as the ATtiny44A series. Cross-family migration to ATmega44P requires significant schematic and firmware adjustments due to architectural differences.
