ATTINY12L-4SI

Overview

The ATTINY12L-4SI is an industrial-grade, low-power CMOS 8-bit microcontroller based on the AVR RISC architecture. It features 1K byte of in-system programmable Flash program memory and 64 bytes of EEPROM data memory. The device operates within a voltage range of 2.7 V to 5.5 V with maximum clock speeds up to 4 MHz. It includes six general-purpose I/O lines, an 8-bit timer/counter, an analog comparator, and a programmable watchdog timer. The component is housed in an 8-pin SOIC package.

Feature Summary

• AVR high-performance 8-bit RISC architecture with single-clock-cycle execution
• In-system programmable nonvolatile Flash and EEPROM memory
• Integrated analog comparator and programmable watchdog timer
• Low-power idle and power-down sleep modes

Applications

• Embedded control applications requiring low power consumption
• Battery-powered devices utilizing internal RC oscillator
• Systems requiring hardware reset and interrupt wake-up capabilities

Procurement Notes

Verify that the specific ordering code matches the required speed grade and temperature range. Confirm the package type corresponds to the design requirements. Ensure compliance with RoHS directives if lead-free packaging is necessary for the manufacturing process. Check current product status as this family may be marked as not recommended for new designs.

Selection Notes

Select this component when a balance of processing speed and low power consumption is required. The ATtiny12L-4 variant specifically supports operation down to 2.7 V, making it suitable for applications where the standard ATtiny12 voltage range is insufficient. Consider the available I/O lines and peripheral features against system complexity.
