Overview
The ATTINY1604-SSNR is an 8-bit AVR microcontroller from Microchip Technology, featuring a 16 kB Flash program memory and 2 kB SRAM. It operates with a maximum clock frequency of 20 MHz and includes a 10-bit ADC with 14 channels. The device provides 12 I/O pins and supports interfaces including I2C, SPI, and USART. It is housed in a 14-SOIC package, rated for industrial temperatures from -40°C to +105°C, and functions within a supply voltage range of 1.8 V to 5.5 V.
Feature Summary
- Integrates a high-performance 8-bit AVR core with up to 20 MHz operation speed.
- Includes extensive analog peripherals such as a 10-bit ADC with multiple channels and an 8-bit DAC.
- Supports flexible communication via I2C, SPI, and USART interfaces.
Applications
- Industrial control systems requiring robust data acquisition
- Battery-powered devices utilizing low-voltage operation
- Sensor interface modules using ADC and communication protocols
Procurement Notes
Verify the specific suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the SOIC-14 configuration. Confirm that the selected variant meets all environmental and electrical requirements for the intended application environment before finalizing procurement.
Selection Notes
Select this component when a balance of processing power and peripheral richness is required in a compact form factor. The 16 kB memory size suits applications needing moderate code storage compared to smaller ATtiny variants. Consider the 14-channel ADC availability if complex signal conditioning is necessary without external multiplexers.
Part Context
This part belongs to the tinyAVR-1 family, designed for cost-sensitive embedded applications. It shares architectural similarities with other members like the ATtiny1614 but offers specific pin counts and memory configurations tailored for general-purpose microcontroller tasks in industrial and consumer electronics.
Replacement Considerations
Direct substitutes include other parts within the tinyAVR-1 series such as the ATtiny1614 or ATtiny3217, provided pinout and memory constraints align. Verify functional equivalence regarding timer counts and ADC channel availability before swapping components in existing designs.
