ATTINY11L-2SU

Overview

The ATTINY11L-2SU is an 8-bit AVR microcontroller in an 8-pin SOIC package. It features a 1K byte 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. Key peripherals include an 8-bit Timer/Counter, an on-chip Analog Comparator, and a programmable Watchdog Timer.

Feature Summary

• AVR RISC architecture delivering up to 1 MIPS throughput at 8 MHz
• Low-power CMOS process technology supporting Idle and Power-down modes
• On-chip Analog Comparator for signal processing applications
• Programmable Watchdog Timer with internal oscillator

Applications

• Embedded control systems requiring low power consumption
• Battery-operated devices utilizing power-saving sleep modes
• Simple sensor interfaces using the analog comparator
• Cost-effective microcontroller solutions for basic logic control

Procurement Notes

Verify the specific suffix 'L-2' corresponds to the 2.7V-5.5V voltage range and 2 MHz speed grade. Confirm the 'SU' designation indicates the SOIC-8 package type. Check manufacturer documentation for current production status as this series may be designated as not recommended for new designs.

Selection Notes

Select this component when a small form factor and minimal I/O count are required. Ensure the application does not exceed the 2 MHz operating limit. Consider the ATtiny12 variant if EEPROM data retention is necessary, as the ATtiny11 lacks this memory.

Part Context

This part belongs to the ATtiny11/12 family, which utilizes high-density nonvolatile memory technology. The ATtiny11 variant specifically excludes EEPROM, distinguishing it from the ATtiny12. The device is manufactured using Atmel's (now Microchip) low-power CMOS process.
