Description
ATtiny402-SSN is Microchip’s tinyAVR 0-series microcontroller in a compact package. It uses an 8-bit AVR RISC core designed for ultra-low power, small-footprint embedded tasks.
Notes:
- SSN suffix indicates a small, low-pin package; verify the exact footprint in the datasheet.
- Peripherals typically include memory (flash, RAM, EEPROM), a 10-bit ADC, timers, and serial interfaces (USART/UART, SPI/USI, I2C/TWI), plus the Event System for peripheral-to-peripheral signaling.
- Power/clock options and sleep modes favor battery-powered applications.
- Programming uses the single-wire UPDI interface (via Microchip Studio or AVR-GCC toolchain).
Typical use cases: battery-powered sensors, wearables, small controllers, IoT edge nodes.
Getting started: read the ATtiny402 datasheet, install Microchip Studio or set up AVR-GCC toolchain, select the -SSN device, wire UPDI for programming, and begin coding.
Note: exact memory sizes and peripheral counts vary by revision; confirm specs from the current datasheet.
