Pinout

The ATTINY402-SSNR is a 8-bit microcontroller from Microchip's ATtiny series, available in an 8-pin SOIC package.
Pin Functions:
1. VDD – Power supply (1.8V–5.5V).
2. GND – Ground.
3. PA1 (UPDI) – Programming/debug interface.
4. PA2 (RESET) – Reset input (optional).
5. PA3 (ADC/CLKOUT) – ADC input or clock output.
6. PA4 (USART TX/ADC) – USART transmit or ADC input.
7. PA5 (USART RX/ADC) – USART receive or ADC input.
8. PA6 (PWM/ADC) – PWM output or ADC input.
Key Features:
- 4KB Flash, 256B SRAM, 128B EEPROM.
- 12-bit ADC, USART, PWM, and timers.
- Operates up to 20MHz.
Compact and versatile for low-power embedded applications.

Application

The ATTINY402-SSNR, a low-power 8-bit microcontroller from Microchip, is ideal for compact, cost-sensitive applications. Key areas include:
- Consumer Electronics: Remote controls, toys, smart home devices.
- Industrial: Sensors, motor control, simple automation.
- IoT: Edge nodes, wearable devices, battery-powered sensors.
- Automotive: Non-critical systems like lighting or switches.
- Embedded Systems: Small control tasks, timers, and GPIO expansions.
Its small size (SOIC-8), low power, and integrated peripherals (ADC, UART, SPI) make it suitable for space-constrained designs.

Package

The ATTINY402-SSNR comes in an 8-pin SOIC (SOIC-8) package. This surface-mount package is compact and widely used for small microcontrollers, offering a balance of size and ease of assembly. The "SSNR" suffix indicates the tape-and-reel packaging for automated assembly. Dimensions are typically 5mm x 6mm with a 1.27mm pin pitch.
