ATTINY11L-2PI

Overview

The ATTINY11L-2PI 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 bytes of general-purpose working registers. The device operates within a voltage range of 2.7V to 5.5V and supports clock frequencies up to 2 MHz. It is housed in an 8-lead Plastic Dual Inline Package (PDIP) and is rated for industrial operating temperatures ranging from -40°C to +85°C.

Feature Summary

• Utilizes high-performance, low-power 8-bit RISC architecture with single-clock-cycle instruction execution.
• Includes an 8-bit Timer/Counter with separate prescaler and programmable Watchdog Timer.
• Features an on-chip Analog Comparator and interrupt/wake-up capability on pin change.
• Supports low-power Idle and Power-down modes with hardware reset circuitry.

Applications

• Embedded control applications requiring low power consumption
• Battery-powered devices utilizing internal RC oscillator
• Simple sensor interfaces using analog comparator
• Cost-effective solutions for basic logic control

Procurement Notes

Verify that the specific ordering code matches the required speed grade and package type. Confirm the industrial temperature rating aligns with environmental requirements. Check current availability status as this component may be subject to lifecycle changes. Ensure compatibility with existing programming tools for the AVR architecture.

Selection Notes

Select this model when a low-cost, low-pin-count solution is needed for simple control tasks. Consider the ATtiny12 variant if EEPROM data retention is required. Evaluate the ATtiny11L-2PC for commercial temperature ranges if industrial ratings are not necessary. Verify power supply constraints against the 2.7V minimum requirement.

Part Context

This component belongs to the ATtiny11/12 family of 8-bit microcontrollers. These devices are designed for applications where code size and cost are critical factors. The family shares a common core architecture but varies in peripheral features like EEPROM presence and maximum clock speeds depending on the specific suffix.
