It runs at 20 MHz and packs 1 KB of Flash program memory, 64 bytes of SRAM, and 64 bytes of EEPROM — enough for simple sensor readouts, PWM dimming, or basic I/O expansion. The 20-QFN package with exposed pad (4x4 mm) saves board area and helps pull heat out when the MCU is driving loads continuously. ## Memory and I/O — sizing the firmware budget With 1 KB of Flash (organized as 512 x 16-bit words), this MCU targets firmware under 1 KB — think a single control loop, a state machine for a button/LED interface, or a simple I²C or SPI slave. The 64-byte SRAM holds a handful of variables and a small stack; the 64-byte EEPROM stores calibration constants or configuration bytes that survive power loss. Six general-purpose I/O pins are available, enough for a few sensor inputs and an output (e.g., driving a MOSFET gate or an LED).","metaTitle":"ATTINY13-20MU AVR 8-bit MCU, 20 MHz, 1 KB Flash, 20-QFN","metaDescription":"Microchip ATTINY13-20MU 8-bit AVR MCU, 20 MHz, 1 KB Flash, 64 B RAM, 64 B EEPROM, 6 I/O, industrial temp -40°C to 85°C, 20-QFN.
