Overview

The ATTINY402-SSF is a high-performance 8-bit AVR microcontroller in a compact 8-pin SOIC package, capable of speeds up to 20MHz. Part of the tinyAVR 0-series, it integrates 4KB of Flash, 256 bytes of SRAM, and 128 bytes of EEPROM, making it an efficient choice for cost-sensitive space-constrained applications. It features advanced hardware peripherals including a hardware multiplier and the Event System for CPU-independent communication between peripherals.

Why Choose This Part

The inclusion of the Event System and Configurable Custom Logic (CCL) allows for complex tasks to be performed without CPU intervention, reducing power consumption. Its single-pin Unified Program and Debug Interface (UPDI) maximizes available I/O, providing 6 pins in an 8-pin package. The hardware multiplier and 125C temperature rating provide performance and reliability advantages over older 8-bit architectures.

Applications

Housekeeping Microcontroller
Managing simple power sequencing, reset logic, or button debouncing in larger systems.
Smart Sensors
Processing analog signals and transmitting data over I2C or UART in a small footprint.
Interface Bridging
Using the hardware USART or SPI to act as a protocol converter between legacy components.
LED Control
Utilizing PWM channels for dimming and color control in decorative or indicator lighting.

Getting Started

Development is supported by Microchip Studio and MPLAB X IDEs using the XC8 compiler. Hardware debugging and programming require a UPDI-compatible tool such as the MPLAB PICkit 4 or the cost-effective MPLAB Snap. For rapid prototyping, the ATtiny402 Curiosity Nano evaluation kit provides a built-in debugger and full access to the pins.
