ATTINY11L-2SI

Overview

The ATTINY11L-2SI is an 8-bit microcontroller based on the AVR RISC architecture, manufactured by Microchip Technology. It features 1K byte of Flash program memory and 32 general-purpose working registers. The device operates within a voltage range of 2.7V to 5.5V with a maximum clock frequency of 2 MHz. It is housed in an 8-lead SOIC package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Utilizes high-performance, low-power 8-bit RISC architecture with single-clock-cycle execution for most instructions.
• Includes peripheral features such as an 8-bit Timer/Counter, programmable Watchdog Timer, and interrupt/wake-up capabilities on pin change.
• Offers software-selectable power-saving modes including Idle and Power-down to optimize energy consumption.

Applications

• Embedded control applications requiring low power consumption
• Battery-operated devices utilizing the AVR RISC architecture
• Industrial systems operating within specified temperature ranges

Procurement Notes

Verify that the component matches the specific ordering code ATTINY11L-2SI to ensure correct speed grade and package type. Confirm the manufacturer details align with Microchip Technology specifications. Check for any updates regarding the 'Not recommended for new design' status before finalizing procurement plans.

Selection Notes

Select this component when a low-cost, 8-bit solution with minimal I/O requirements is needed. Consider the 2 MHz speed limit and 2.7V minimum supply voltage. Evaluate if the lack of EEPROM meets project data retention needs compared to the ATtiny12 variant.

Part Context

This part belongs to the ATtiny11/12 family, which are low-power CMOS 8-bit microcontrollers. The series is characterized by its ability to achieve nearly 1 MIPS per MHz throughput. The ATtiny11 specifically lacks EEPROM, distinguishing it from the ATtiny12 model within the same architectural family.
