ATTINY11-6SI

Overview

The ATTINY11-6SI is an 8-bit microcontroller based on the AVR RISC architecture, manufactured by Microchip Technology (formerly Atmel). It features 1K byte of Flash program memory and 32 general-purpose working registers. The device operates within a voltage range of 4.0V to 5.5V with a maximum clock frequency of 6 MHz. It is housed in an 8-lead Plastic Gull-Wing Small Outline (SOIC) package, designated as package type 8S2. The component is rated for industrial operating temperatures ranging from -40°C to +85°C.

Feature Summary

• High-performance 8-bit RISC architecture executing most instructions in a single clock cycle
• Low-power CMOS technology supporting Idle and Power-down sleep modes
• Integrated 8-bit Timer/Counter with separate prescaler and programmable Watchdog Timer
• On-chip Analog Comparator and interrupt/wake-up capability on pin change

Applications

• Embedded control applications requiring low power consumption
• Battery-powered systems utilizing power-saving modes
• Simple peripheral interfacing via analog comparator and timer/counters

Procurement Notes

Verify that the specific ordering code matches the required speed grade and voltage range for your design. Confirm the package type corresponds to the 8-lead SOIC variant. Check current availability status as this product summary indicates it is not recommended for new designs. Ensure compliance with RoHS directives if lead-free packaging is required for your assembly process.

Selection Notes

Select this component only if the application fits within the 4.0V to 5.5V supply voltage constraints. Consider the 6 MHz maximum frequency limit when evaluating processing requirements. Note that unlike the ATtiny12 variant, this model lacks EEPROM memory. Evaluate the trade-off between the single-clock-cycle execution efficiency and the limited I/O lines available on the 8-pin package.

Part Context

This device belongs to the ATtiny11/12 family of 8-bit microcontrollers. It shares the same core AVR architecture and peripheral set as the ATtiny12 but differs in memory configuration and voltage specifications. The ATtiny11 series provides Flash memory without onboard EEPROM, distinguishing it from the EEPROM-equipped ATtiny12 models within the same datasheet documentation.

Replacement Considerations

Public confirmed substitute part numbers: ATtiny11L-2SI, ATtiny11-6SU.
