ATTINY45V-10SUR

Overview

The ATTINY45V-10SUR is an 8-bit AVR microcontroller featuring 4K bytes of In-System Programmable Flash, 256 bytes of EEPROM, and 256 bytes of SRAM. It operates at a maximum clock frequency of 10 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes six programmable I/O lines, a 10-bit ADC with four single-ended channels, two high-speed PWM outputs, and a Universal Serial Interface (USI). It utilizes an 8-lead TSSOP package in tape and reel format.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for efficient processing.
• Non-volatile memory with high endurance specifications for program flash and data EEPROM.
• 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 low active and standby current consumption.
• Industrial control applications utilizing the Universal Serial Interface for communication.
• Sensor interface circuits leveraging the 10-bit ADC and on-chip temperature measurement capabilities.

Procurement Notes

Verify that the ordering suffix 'R' corresponds to the tape and reel packaging configuration as specified in the manufacturer's documentation. Confirm the 'V' designation indicates the extended 1.8 V minimum supply voltage capability. Ensure the '10' speed grade matches the required operational frequency for the target application environment.

Selection Notes

Select this component when 4K bytes of program memory and 256 bytes of data storage are sufficient for the application logic. Choose the TSSOP package if surface mount assembly with specific footprint constraints is required. Verify that the industrial temperature range meets the environmental conditions of the deployment site.

Part Context

This part belongs to the ATtiny45/V family within the broader ATtiny25/45/85 series. It shares the same core architecture and peripheral set as the ATtiny25V and ATtiny85V, differentiated primarily by its internal memory capacities. The device is manufactured using high-density non-volatile memory technology compatible with standard SPI programming interfaces.

FAQ

Is the ATTINY45V-10SUR available in a through-hole package?

No, the 'SUR' suffix specifically denotes the 8-lead Thin Shrink Small Outline Package (TSSOP) in tape and reel format. Through-hole options such as PDIP are designated with different suffixes like 'PU'.

What is the minimum operating voltage for this specific variant?

The 'V' in the part number indicates it supports a minimum supply voltage of 1.8 V, unlike the standard ATtiny45 which requires a minimum of 2.7 V.
