The DMA offloads peripheral-to-memory transfers (ADC results, UART buffers) so the core stays free for protocol stack processing. The MSP430F5509IZQER carries an official lifecycle status of Obsolete. TI has ended production; there is no last-time-buy window remaining. New designs should not target this order code. No direct factory support or PCN notifications apply to this code going forward. ## 80-BGA MICROSTAR JUNIOR — board-level reality This part is supplied in an 80-VFBGA package (MICROSTAR JUNIOR, 5x5 mm body).","metaTitle":"TI MSP430F5509IZQER 16-bit MCU, 25MHz, 24KB Flash, 80-BGA","metaDescription":"Texas Instruments MSP430F5509IZQER 16-bit MCU, 25MHz core, 24KB Flash, 6K x 8 RAM, USB 2.0, 80-BGA MICROSTAR JUNIOR.","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":"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, LINbus, SCI, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"47","Core Processor":"MSP430 CPUXV2","Package / Case":"80-VFBGA","Product Status":"Obsolete","Data Converters":"A/D 12x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F5509","Program Memory Size":"24KB (24K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"80-BGA MICROSTAR JUNIOR (5x5)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/82530e26136b4d9d3a70005cd9092a5d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MSP430F5509IZQER obsolete?","answer":"Yes.
