ATTINY1604-SSFR

Overview

The ATTINY1604-SSFR is an 8-bit AVR microcontroller from the tinyAVR 1-Series family, manufactured by Microchip Technology. It features a maximum clock frequency of 20 MHz and includes 16 KB of Flash program memory, 1 KB of SRAM, and 128 B of EEPROM. The device provides 15 I/O pins and operates within a supply voltage range of 1.8 V to 5.5 V. It integrates a 12-bit ADC with 15 channels, three 16-bit timers/counters, and communication interfaces including SPI, USART, and I2C. The component is housed in a 14-SOIC package and supports industrial temperature ranges.

Feature Summary

• Integrates a high-resolution 12-bit Analog-to-Digital Converter (ADC) with multiple input channels for precise signal acquisition.
• Includes advanced peripheral modules such as Event System, Real-Time Counter (RTC), and Capture/Compare units for complex timing control.
• Supports flexible communication protocols via dedicated hardware interfaces for SPI, USART, and I2C connectivity.

Applications

• Industrial sensor nodes requiring high-resolution analog measurement
• Battery-powered devices utilizing low-voltage operation capabilities
• Embedded systems needing precise timing control via hardware timers

Procurement Notes

Verify the specific suffix 'SSFR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the industrial temperature grade aligns with the operational environment specifications of the target application. Ensure compatibility with existing programming tools supporting the AVR architecture.

Selection Notes

Select this model when higher code capacity than the 8-bit variants is necessary while maintaining small form factor constraints. Consider the enhanced peripheral set compared to basic AVR controllers if event-driven architectures or high-speed data conversion are required. Evaluate pin count requirements against the available 15 I/O options.

Part Context

This component belongs to the tinyAVR 1-Series family, designed for applications demanding enhanced performance over legacy 8-bit controllers. It bridges the gap between simple microcontrollers and more complex 32-bit ARM-based solutions, offering a balance of processing power, peripheral richness, and cost efficiency for embedded designs.

Replacement Considerations

Direct substitutes within the same series include ATTINY1604-MFR and ATTINY1604-SSU. Cross-series migration may require firmware adaptation due to architectural differences in register sets and interrupt handling mechanisms.
