ATTINY12V-1SU

Overview

The ATTINY12V-1SU is an 8-bit AVR microcontroller featuring a 1K byte Flash program memory and 64 bytes of in-system programmable EEPROM. It operates within a voltage range of 1.8 to 5.5 volts and supports clock frequencies up to 1.2 MHz. The device utilizes the AVR RISC architecture, achieving up to 1 MIPS throughput at 8 MHz. It includes 32 general-purpose working registers, six I/O lines, an 8-bit timer/counter, an analog comparator, and a programmable watchdog timer.

Feature Summary

• Utilizes high-performance, low-power 8-bit RISC architecture with single-clock-cycle instruction execution
• Features nonvolatile memory including 1K byte Flash and 64 bytes EEPROM for data retention
• Integrates peripheral functions such as an 8-bit timer/counter, analog comparator, and programmable watchdog timer
• Supports low-power operation through Idle and Power-down modes with wake-up capabilities

Applications

• Embedded control applications requiring low power consumption
• Battery-powered devices utilizing extended standby modes
• Simple sensor interfaces using analog comparator functionality
• Basic logic control systems with limited I/O requirements

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches SOIC-8 dimensions and pinout configuration. Ensure ordering suffixes align with required speed grades and temperature ranges. Validate RoHS compliance status if environmental regulations apply to the specific manufacturing batch.

Selection Notes

Select this component when a low-voltage operation down to 1.8V is required alongside minimal memory capacity. Consider the ATtiny12V series for applications needing basic interrupt handling and timer functions without complex communication interfaces. Evaluate power consumption metrics against system duty cycles to ensure battery life meets design targets.

Part Context

This device belongs to the ATtiny11/12 family of 8-bit microcontrollers manufactured by Microchip Technology (formerly Atmel). The V suffix indicates a wide voltage operating range starting at 1.8V, while the 1 suffix denotes the maximum frequency grade. The SU suffix specifies the surface-mount SOIC package variant designed for industrial temperature ranges.

Replacement Considerations

Direct substitutes include other ATtiny12 variants with adjusted voltage or speed ratings, such as ATtiny12L-4SU or ATtiny12-8SU. Cross-referencing pin compatibility and memory sizes is essential when selecting alternative components from different manufacturers.
