ATTINY261A-MNR

Overview

The ATTINY261A-MNR is an 8-bit AVR microcontroller featuring 2 KB of In-System Programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. It operates at a maximum clock frequency of 20 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes a 10-bit ADC with 11 single-ended channels, 16 I/O lines, and a Universal Serial Interface (USI). It utilizes a 32-pad Micro Lead Frame Package (MLF) with dimensions of 5 x 5 mm.

Feature Summary

• Advanced RISC architecture achieving up to 20 MIPS throughput at 20 MHz
• Integrated 10-bit Analog-to-Digital Converter with multiple channel options
• Supports in-system programming via SPI interface for flash memory updates
• Includes programmable Watchdog Timer and four software-selectable power-saving modes

Applications

• Battery-powered embedded systems requiring low power consumption
• Industrial control applications utilizing the industrial temperature range
• Sensor interfaces leveraging the on-chip ADC and analog comparator
• Communication nodes using the Universal Serial Interface (USI)

Procurement Notes

Verify that the ordering suffix 'MNR' corresponds to the specific package type and tape & reel configuration required for your assembly process. Confirm the industrial temperature rating (-40°C to +105°C) aligns with your environmental specifications. Ensure compatibility with your existing design tools and development kits before finalizing procurement.

Selection Notes

Select this component when a compact 32-pin MLF package is preferred over larger QFN or standard DIP packages. It is suitable for designs needing 2 KB of program memory and a 10-bit ADC within a small footprint. Consider the extended industrial temperature range if operating conditions exceed commercial limits.

Part Context

This part belongs to the ATtinyx61A series of 8-bit microcontrollers based on the AVR enhanced RISC architecture. It shares core features with the ATtiny461A and ATtiny861A, differing primarily in non-volatile memory capacities. The series is designed for high performance and low power consumption in space-constrained applications.

Replacement Considerations

ATtiny261A-MU: Same electrical specifications but in a 32-pad MLF package without tape & reel packaging.
