Overview
The ATtiny402-SSNR is an 8-bit AVR microcontroller featuring 4 KB of Flash memory, 128 bytes of SRAM, and 64 bytes of EEPROM. It operates at a maximum clock frequency of 20 MHz within a voltage range of 1.8 V to 5.5 V. The device includes a 10-bit ADC with 115 ksps sampling rate, three-channel Event System, TCA/TCB timers, USART, SPI, and TWI interfaces. It utilizes the Single Pin Unified Program Debug Interface (UPDI) for programming and debugging.
Feature Summary
- Integrates picoPower technology with configurable peripherals and SleepWalking capabilities for optimized power management.
- Features a high-performance 8-bit AVR RISC CPU capable of executing instructions in a single cycle.
- Includes advanced analog subsystems such as a 10-bit ADC and Analog Comparator with selectable internal voltage references.
Applications
- Battery-powered sensor nodes
- Smart home control devices
- Industrial monitoring systems
Procurement Notes
Verify the specific suffix 'SSNR' indicates tape and reel packaging when ordering. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the operating temperature range aligns with your system's environmental specifications before finalizing procurement.
Selection Notes
Select this model if your design requires 4 KB of program memory and up to 6 programmable I/O lines. Consider the ATtiny402 for applications needing precise timing via the RTC or low-power operation through multiple sleep modes. Evaluate the peripheral set against your communication protocol requirements.
Part Context
This component belongs to the tinyAVR 0-Series family, designed for cost-sensitive embedded applications. It shares architectural similarities with the ATtiny202 but offers double the Flash and SRAM capacity. The series emphasizes low power consumption while maintaining high processing speeds.
Replacement Considerations
The ATtiny202 serves as a lower-memory alternative within the same package. Verify pin compatibility and software library support when substituting components from different memory density variants within the tinyAVR 0-Series family.
FAQ
What is the function of the UPDI interface?
The Single Pin Unified Program Debug Interface (UPDI) combines programming, debugging, and configuration functions onto a single pin, simplifying the development process.
How does SleepWalking benefit the system?
SleepWalking allows selected peripherals to operate independently while the CPU is asleep, enabling event-driven wake-ups without consuming significant power.
