It integrates an internal oscillator, an 8-channel 10-bit ADC, and a Universal Serial Interface (USI) for simple serial communication. ## Peripheral set for low-pin-count control tasks These are the building blocks for a self-contained controller that can handle a brushed DC motor, read a thermistor, and keep a watchdog alive without external supervisory ICs. The 12 I/O lines are enough for a few pushbuttons, an LED bank, and a serial link to a host processor. That means no last-time-buy clock is ticking — the storeroom can stock these without worrying about an EOL notice next quarter. ## Through-hole package — rework and prototyping friendly The DIP-14 package is a through-hole part, which means it fits breadboards, perfboards, and sockets. For a repair lab or a low-volume production run, this is a practical advantage: no hot-air rework station needed, and the part can be swapped in seconds. The 0.3-inch row spacing is standard for DIP sockets.","metaTitle":"ATTINY24A-PU Microchip AVR 8-bit MCU, 2KB Flash, 20 MHz","metaDescription":"Microchip ATTINY24A-PU 8-bit AVR MCU with 2KB Flash, 20 MHz, 12 I/O, 8x10b ADC, USI, internal oscillator, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"series":"AVR® ATtiny","has_mpn":"ATTINY24","cpu_core":"AVR","frame_size":"8-Bit","fuse_speed":"20 MHz","connectivity":"USI","package_type":"Bulk","Number Of I/O":"12","mounting_type":"Through Hole","product_status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","peripheral_types":"Brown-out Detect/Reset, POR, PWM, Temp Sensor, WDT","supply_voltage_v":"1.8","Program Memory Type":"FLASH","Operating Temperature High":"-40°C to 85°C (TA)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.53","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ATTINY24A-PU/alternatives.json"},"ai":{"faq":[{"question":"How to program ATTINY24A-PU?","answer":"The ATTINY24A-PU uses the AVR ISP (In-System Programming) interface, accessible via the standard 6-pin header (MISO, MOSI, SCK, RESET, VCC, GND).
