ATTINY104F-SSFR

Overview

The ATTINY104F-SSFR is an 8-bit AVR microcontroller featuring 1024 bytes of in-system programmable Flash, 32 bytes of SRAM, and a fully static architecture. It operates within a voltage range of 1.8V to 5.5V and supports clock frequencies up to 12MHz at the upper voltage limit. The device includes one 16-bit Timer/Counter with two PWM channels, a 10-bit ADC with eight channels, and a USART module. It utilizes a 14-pin SOIC package and 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.
• Supports multiple low-power modes including Idle, ADC Noise Reduction, and Power-down.
• Features fast start-up time options and an accurate internal calibrated oscillator.

Applications

• Battery-powered embedded systems requiring extended data retention.
• Industrial control applications utilizing serial communication protocols.
• Sensor interface circuits employing analog-to-digital conversion.
• General-purpose logic replacement in compact surface-mount designs.

Procurement Notes

Verify that the specific suffix 'F' corresponds to the fast start-up time option as documented in the ordering information table. Confirm the package type matches the required 14-pin SOIC dimensions. Ensure the speed grade aligns with the target operating voltage and frequency requirements specified in the datasheet.

Selection Notes

Select this component when system design requires a balance between processing speed and power consumption. The 14-pin configuration provides sufficient I/O lines for peripheral integration compared to smaller packages. Consider the fast start-up feature if rapid system initialization is critical for the application timing constraints.

Part Context

This part belongs to the ATtiny102/ATtiny104 family of 8-bit AVR microcontrollers manufactured by Microchip Technology (formerly Atmel). The 'F' designation indicates the inclusion of the fast start-up time option. It shares core architectural features with the ATtiny102 but offers increased I/O capacity through the 14-pin package variant.

Replacement Considerations

The ATtiny104-SSFR serves as the standard alternative without the fast start-up feature. Cross-referencing with other ATtiny series devices may require significant code adaptation due to differences in register sets and peripheral configurations.

FAQ

What is the function of the 'F' suffix in the part number?

The 'F' suffix indicates that the device includes the fast start-up time option, allowing for quicker system initialization compared to the standard version.

How does the device handle program memory reprogramming?

The device supports self-programming Flash on the full operating voltage range (1.8V to 5.5V) and allows in-system programming via external programmers.
