ATtiny13A-SU SMD 8‑Bit 20 MHz Microcontroller ⚙️

The ATtiny13A‑SU is a compact, energy‑efficient 8‑bit AVR RISC microcontroller from Microchip, packaged in a SOIC‑8 SMD form factor. Designed for embedded control, sensor interfacing, and compact modules, it integrates 1 KB In‑System Programmable (ISP) Flash, 64 B SRAM, 64 B EEPROM, an 8‑bit timer/counter with PWM, and a 4‑channel 10‑bit ADC. Running up to 20 MHz (with appropriate clock source and voltage), it’s ideal for both electronics hobbyists and professional engineers building Arduino- or Raspberry Pi‑adjacent projects and custom electronics modules.
