ATTINY104-SSNR

Overview

The ATTINY104-SSNR is an 8-bit AVR microcontroller featuring a 14-pin SOIC150 package. It includes 1024 bytes of in-system programmable Flash, 32 bytes of SRAM, and 12 general-purpose I/O lines. The device supports a maximum clock frequency of 12 MHz and operates within a voltage range of 1.8 V to 5.5 V. Key peripherals include a 16-bit Timer/Counter with two PWM channels, a 10-bit ADC with eight channels, an analog comparator, and a USART module. It functions across a temperature range of -40°C to +125°C.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for high throughput efficiency.
• Integrated non-volatile memory with self-programming capabilities across the full operating voltage range.
• Multiple low-power operational modes including Idle, ADC Noise Reduction, and Power-down.
• Comprehensive peripheral set including a 16-bit Timer/Counter, 10-bit ADC, Analog Comparator, and USART.

Applications

• Low-power embedded control systems
• Battery-operated sensor nodes
• Industrial monitoring devices
• Consumer electronics requiring compact MCU solutions

Procurement Notes

Verify that the specific ordering code matches the required speed grade and industrial temperature range (-40°C to +125°C). Confirm the package type is the 14-lead SOIC150 variant. Ensure compatibility with existing programming interfaces and development toolchains before finalizing procurement decisions.

Selection Notes

Select this component when a balance of processing speed and pin count is required within a small footprint. The 14-pin configuration provides sufficient I/O for moderate complexity applications while maintaining low power consumption characteristics inherent to the AVR enhanced RISC architecture.

Part Context

This part belongs to the ATtiny102/ATtiny104 family manufactured by Microchip Technology (formerly Atmel). It shares the same core architecture and memory specifications as the ATtiny102 but offers increased I/O capacity through a 14-pin package instead of an 8-pin package.

Replacement Considerations

The ATtiny102-SSNR serves as a direct functional substitute if fewer than seven I/O lines are sufficient for the application design requirements.

FAQ

Does the ATTINY104-SSNR support self-programming?

Yes, the device features self-programming Flash capabilities that operate across the full voltage range of 1.8 V to 5.5 V.

What is the resolution of the onboard ADC?

The integrated Analog-to-Digital Converter has a 10-bit resolution and supports up to eight input channels on the 14-pin package.
