The 6 KB SRAM, organised as 6K x 8, handles the packet buffers and stack frames; if your design queues USB transactions, budget that space carefully. ## USB device controller — the feature that sets this part apart Not every MSP430 in the F5xx family includes a USB module. If your design needs a USB link for firmware update, data logging, or HID-class communication, this part saves an external USB-to-serial bridge. The 31 GPIO lines remain available even with USB active, though the D+ and D- pins are dedicated.","metaTitle":"Texas Instruments MSP430F5505IRGZR 16-bit MCU, 25 MHz","metaDescription":"Texas Instruments MSP430F5505IRGZR — 16-bit MSP430 CPUXV2 at 25 MHz, 16 KB Flash, 6 KB SRAM, USB 2.0 device controller, 8-ch 10-bit ADC, 31 GPIO, 1.8-3.6 V","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)","RAM Size":"6K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"31","Core Processor":"MSP430 CPUXV2","Package / Case":"48-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F5505","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"48-VQFN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4131","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cb104fd0bb5fc5c2e92db6a1d45710aa.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the flash and RAM size of MSP430F5505IRGZR?","answer":"Program memory is 16 KB (16K x 8) of Flash, and RAM is 6 KB (6K x 8).
