The 4 KB SRAM limits buffering, so any application that queues data (e.g., logging sensor reads over I²C) needs careful sizing. The 32 GPIOs in a 48-LQFP package give reasonable pinout for a small board, but the 4x10-bit ADC is basic — don't plan on high-resolution analog acquisition.","metaTitle":"LM3S316-IQN25-C2 Stellaris ARM Cortex-M3 MCU, 25 MHz","metaDescription":"LM3S316-IQN25-C2 is a 32-bit ARM Cortex-M3 MCU with 25 MHz core, 16 KB Flash, 4 KB SRAM, industrial temp range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"25MHz","Series":"Stellaris® ARM® Cortex®-M3S 300","Package":"Tray","RAM Size":"4K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"32","Core Processor":"ARM® Cortex®-M3","Package / Case":"48-LQFP","Product Status":"Obsolete","Data Converters":"A/D 4x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S316","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"3V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.7800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/390a0dd8f415a72ded60f3709e1ec55a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S316-IQN25-C2/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S316-IQN25-C2 obsolete?","answer":"Yes, the LM3S316-IQN25-C2 is listed as Obsolete.
