That saves two I/O pins and reduces BOM count. The internal oscillator is factory-calibrated; if tighter timing is needed, the part also accepts an external clock source. A 3.7 V Li-ion cell or a 5 V USB bus can power the MCU directly. The 105°C ceiling gives margin above the typical 85°C industrial limit, which helps with derating in sealed or high-ambient enclosures.","metaTitle":"ATTINY13-20SQ AVR ATtiny 8-bit MCU, 20 MHz, 1 KB Flash","metaDescription":"Microchip ATTINY13-20SQ 8-bit AVR MCU, 20 MHz, 1 KB Flash, 64 B SRAM, 6 I/O, 4x10b ADC, -40°C to 105°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":"AVR® ATtiny","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Microchip Technology","Speed":"20MHz","Series":"AVR® ATtiny","Package":"Tube","RAM Size":"64 x 8","Core Size":"8-Bit","EEPROM Size":"64 x 8","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"-","Mounting Type":"Surface Mount","Number of I/O":"6","Core Processor":"AVR","Package / Case":"8-SOIC (0.209\\\", 5.30mm Width)","Product Status":"Active","Data Converters":"A/D 4x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"ATTINY13","Program Memory Size":"1KB (512 x 16)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~105°C(TA)","Supplier Device Package":"8-SOIC","Voltage - Supply (Vcc/Vdd)":"2.7V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4400","priceTiers":[{"qty":210,"price":"$1.44000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b54d99a29d7b3dfce849beaccfc3950a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ATTINY13-20SQ/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between ATTINY13-20SQ and ATTINY13-20SSU?","answer":"The difference is the package and temperature grade.
