Overview

The ATTINY13A-SU is a low-power 8-bit AVR RISC-based microcontroller featuring 1KB of ISP Flash and 64 bytes of SRAM in a compact 8-pin package. Operating at up to 20MHz, it is designed for cost-sensitive applications that require minimal board space and low power consumption.

Why Choose This Part

The ATTINY13A offers a highly efficient power profile, drawing as little as 0.35 mA at 1MHz while maintaining full functional capability. Its high-endurance non-volatile memory and internal calibrated oscillator allow for robust, standalone operation without external timing components.

Applications

Battery-Powered Consumer Devices
Ideal for simple handheld gadgets and toys where 2uA sleep current and wide 1.8V to 5.5V operating voltage extend battery life.
Logic Replacement
Replaces multiple discrete logic gates or timer ICs with a single programmable component to reduce PCB complexity.
Sensor Interface
Acts as a dedicated peripheral controller for simple analog-to-digital conversions or signal conditioning at the edge.

Getting Started

Development is supported by the Microchip Studio IDE and the XC8 compiler. Hardware programming can be performed via the SPI interface using an AVR ISP mkII or through the debugWIRE on-chip debug system for real-time emulation.
