ATTINY414-SSFR

Overview

The ATTINY414-SSFR is an 8-bit AVR microcontroller from Microchip Technology, housed in a 14-pin SOIC package. It features 4 kB of Flash program memory, 256 B of SRAM, and 128 B of EEPROM. The device supports a maximum clock frequency of 20 MHz and operates within a supply voltage range of 1.8 V to 5.5 V. It includes a 10-bit ADC with 10 channels, 12 general-purpose I/Os, and interfaces such as I2C, SPI, and USART. The component is rated for industrial temperatures from -40°C to +125°C.

Feature Summary

• Integrates a high-performance 8-bit AVR RISC core capable of executing complex instructions in a single clock cycle.
• Includes a 10-bit analog-to-digital converter with multiple input channels for precise signal acquisition.
• Supports standard serial communication protocols including I2C, SPI, and USART for system connectivity.
• Features non-volatile memory structures with specified endurance ratings for program and data storage.

Applications

• Industrial control systems requiring robust operation across wide temperature ranges
• Battery-powered devices utilizing low-power consumption modes
• Sensor interface modules using the integrated ADC capabilities
• Communication nodes employing serial protocol stacks

Procurement Notes

Verify the specific suffix SSFR corresponds to the SOIC-14 package and tape-and-reel shipping configuration required for your assembly line. Confirm that the industrial temperature grade (-40°C to +125°C) meets your environmental specifications. Ensure compatibility with your programming interface for the AVR architecture before finalizing procurement orders.

Selection Notes

Select this component when a balance of moderate code capacity (4 kB) and peripheral richness is needed in a compact 14-pin form factor. It is suitable for applications where 12 I/O lines and a 10-bit ADC are sufficient, distinguishing it from higher-memory variants or simpler pin-count models. Consider the 20 MHz performance limit against your processing requirements.

Part Context

This part belongs to the ATtiny414 series within the tinyAVR family. It shares architectural similarities with other members like the ATTINY417 but differs in package type and specific peripheral configurations. The series emphasizes low power and functional safety features for embedded control tasks.

Replacement Considerations

Direct pin-compatible replacements within the same package may include other ATtiny41x variants with adjusted memory sizes. Verify electrical characteristics and peripheral availability when substituting with similar 8-bit AVR controllers from different manufacturers.
