Typical applications span USB-based data loggers, sensor gateways, portable medical devices, and industrial control panels where the USB interface offloads host communication without an external bridge chip. ## 25 MHz clock and wake-up energy budget The 25 MHz CPU clock is the top end for this MSP430F5xx part. In a battery-powered LoRa or Zigbee sensor node, running the core at full speed during brief active windows and then dropping into a low-power sleep mode is the standard strategy. The 6K x 8 RAM limits packet buffers — a USB CDC-ACM virtual COM port with a 512-byte buffer plus a 1 KB sensor data queue leaves about 4.5 KB for stack and variables, which is tight for a full TCP/IP stack but comfortable for a custom serial protocol or a lightweight CoAP endpoint. The 80-LQFP (12x12 mm) with 0.5 mm pitch is a common footprint for medium-complexity MCUs; it routes easily on a two-layer board with a ground plane under the USB differential pair. No exposed thermal pad — the package dissipates through the leads, so keep the ambient below 85°C if the I/O load is high. ## Lifecycle and sourcing posture Texas Instruments lists the MSP430F5525IPNR with an Active product status. For dual-sourcing resilience, the MSP430F5529 (with 128 KB Flash and 10K x 8 RAM) is a drop-in software-compatible upgrade in the same package, though the extra memory and slightly different peripheral set require a firmware recompile.","metaTitle":"TI MSP430F5525IPNR 16-bit MCU, 25 MHz, 64 KB Flash, 80-LQFP","metaDescription":"Texas Instruments MSP430F5525IPNR 16-bit MCU with 25 MHz CPU, 64 KB Flash, 6K x 8 RAM, USB 2.0, industrial temp -40°C to 85°C, 80-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"25MHz","Series":"MSP430F5xx","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"6K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SCI, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"63","Core Processor":"MSP430 CPUXV2","Package / Case":"80-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F5525","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"80-LQFP (12x12)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.9961","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f9bc2af01f4cd3dcd4e6ac942ebe2ec3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for MSP430F5525IPNR?","answer":"There is no direct replacement announced by Texas Instruments. The MSP430F5529 (128 KB Flash, 10K x 8 RAM) is a software-compatible higher-density sibling in the same 80-LQFP package, but it is not a pin-for-pin substitute — firmware changes are required. For a like-for-like swap, source the MSP430F5525IPNR through independent distribution."},{"question":"What programmer works with MSP430F5525IPNR?","answer":"Any TI MSP430 Flash programmer or debugger that supports the Spy-Bi-Wire (SBW) or JTAG interface works with this MCU. Common options include the MSP-FET430UIF, MSP-FET, and the eZ-FET Lite integrated on TI LaunchPad boards. The SBW two-wire interface is the simplest for production programming."},{"question":"How does MSP430F5525IPNR compare to MSP430F5529?","answer":"The MSP430F5529 doubles the Flash to 128 KB and RAM to 10K x 8, and adds a second USB module. Both share the same 25 MHz CPUXV2 core, 80-LQFP package, and peripheral set. The MSP430F5525IPNR is the cost-optimised choice when 64 KB Flash and 6K RAM are sufficient; the F5529 targets applications needing more code space or dual-USB capability."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F5525IPNR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F5525IPNR when reusing this data.
