The 2 KB Flash is the hard limit for compiled code — expect to fit a UART polled handler, a few GPIO toggles, and a small state machine.","metaTitle":"ATTINY2313A-MUR AVR 8-bit MCU, 20 MHz, 2 KB Flash, 20-QFN","metaDescription":"Microchip ATTINY2313A-MUR 8-bit AVR MCU: 20 MHz core, 2 KB Flash, 128 B RAM, 128 B EEPROM, 18 I/O, 1.8-5.5 V, -40 to 85°C, 20-QFN.","metaKeywords":null},"attributes":{"series":"AVR® ATtiny","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Microchip Technology","Speed":"20MHz","Series":"AVR® ATtiny","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"128 x 8","Core Size":"8-Bit","EEPROM Size":"128 x 8","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"18","Core Processor":"AVR","Package / Case":"20-WFQFN Exposed Pad","Product Status":"Active","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"ATTINY2313","Program Memory Size":"2KB (1K x 16)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"20-QFN-EP (4x4)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0800","priceTiers":[{"qty":1,"price":"$1.08000","currency":"USD"},{"qty":25,"price":"$0.97760","currency":"USD"},{"qty":100,"price":"$0.88550","currency":"USD"},{"qty":6000,"price":"$0.88550","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d3438213ba0cc8ab2a065225e428e28d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ATTINY2313A-MUR/alternatives.json"},"ai":{"faq":[{"question":"How do I program ATTINY2313A-MUR?","answer":"Programming is done through the AVR ISP (In-System Programming) interface using the SPI pins, or via a debugWIRE one-wire debugger.
