Overview
The ATTINY402-SSF is an 8-bit AVR microcontroller from the tinyAVR 0-Series, featuring 4 KB of self-programmable Flash memory, 256 bytes of SRAM, and 128 bytes of EEPROM. It operates at clock speeds up to 20 MHz with a supply voltage range of 1.8V to 5.5V. The device includes a 10-bit ADC, three timers (TCA, TCB, RTC), USART, SPI, TWI, and Configurable Custom Logic (CCL). It utilizes a Single Pin Unified Program Debug Interface (UPDI) for programming and debugging.
Feature Summary
- Integrates picoPower technology with configurable sleep modes including SleepWalking for low-power operation.
- Features core-independent peripherals such as CCL and Event System to offload tasks from the CPU.
- Includes accurate internal oscillators with ±3% accuracy over full temperature and voltage ranges.
Applications
- Battery-powered sensor nodes
- Smart home control units
- Industrial monitoring devices
Procurement Notes
Verify the specific suffix 'SSF' corresponds to the SOIC-8 package and tape-and-reel quantity specified in the official Microchip ordering guide. Confirm RoHS compliance and lead times directly with authorized distributors or the manufacturer before procurement.
Selection Notes
Select this model when 4 KB of program memory and 256 bytes of RAM are required within an 8-pin footprint. Ensure the application supports the 1.8V to 5.5V operating range and requires the specific peripheral mix of TCA, TCB, and RTC available in the tinyAVR 0-Series.
Part Context
This component belongs to the ATtiny202/402 family within the tinyAVR 0-Series. It shares architectural similarities with the ATtiny202 but offers double the Flash and SRAM capacity. The series emphasizes low power consumption and advanced analog features for embedded applications.
Replacement Considerations
ATtiny202-SSF: Offers identical pinout and peripherals but with reduced memory (2 KB Flash, 128 B SRAM). Verify if the smaller memory footprint meets application requirements.
FAQ
What is the maximum operating frequency of the ATTINY402-SSF?
The device can run at up to 20 MHz depending on the supply voltage and speed grade configuration.
How many I/O lines are available on the 8-pin package?
The ATTINY402-SSF provides six programmable I/O lines in its 8-pin SOIC package.
