The 16 KB SRAM supports moderate data buffers (e.g., a 4 KB TCP/IP packet buffer plus sensor logs). ROHS3 compliance is confirmed on the record, so it passes EU regulatory screening without an exemption review.","metaTitle":"Microchip AVR128DA28-E/SO 8-bit MCU, 128KB Flash, 24MHz","metaDescription":"Microchip AVR128DA28-E/SO 8-bit MCU: 128KB Flash, 16KB RAM, 512B EEPROM, 24MHz, -40°C to 125°C, 28-SOIC.","metaKeywords":null},"attributes":{"series":"AVR® DA","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Microchip Technology","Speed":"24MHz","Series":"AVR® DA","Package":"Tube","RAM Size":"16K x 8","Core Size":"8-Bit","EEPROM Size":"512 x 8","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"23","Core Processor":"AVR","Package / Case":"28-SOIC (0.295\\\", 7.50mm Width)","Product Status":"Active","Data Converters":"A/D 10x12b; D/A 1x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"AVR128DA28","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"28-SOIC","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3700","priceTiers":[{"qty":1,"price":"$2.37000","currency":"USD"},{"qty":25,"price":"$2.16200","currency":"USD"},{"qty":100,"price":"$1.96650","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6ebeca26d61da2f055d6c85d4127bf34.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/AVR128DA28-E%2FSO/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source for AVR128DA28-E/SO?","answer":"The AVR32DD28T-I/SS is a pin-compatible 8-bit AVR MCU in the same 28-SOIC footprint, but it carries 32 KB Flash (vs. 128 KB) and is rated only to 85°C, not 125°C.
