The 16 MHz clock is enough for UART/SPI/I²C protocol handling and moderate sensor fusion loops. ## 31 I/O and the peripheral set — what connects where With 31 general-purpose I/O lines in a 38-TSSOP package, you get enough pins for a small keypad, a character LCD, and a few sensor interrupts alongside the serial interfaces. The on-chip peripherals include a 12-channel 12-bit ADC, brown-out reset, POR, DMA, PWM, and a watchdog timer.","metaTitle":"MSP430FR5859IDA 16-bit MCU, 64 KB FRAM, 16 MHz, 38-TSSOP","metaDescription":"MSP430FR5859IDA 16-bit MCU with 64 KB FRAM, 2 KB SRAM, 16 MHz CPUXV2 core, 31 I/O, 1.8-3.6 V, -40 to 85°C, 38-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"16MHz","Series":"MSP430™ FRAM","Package":"Tube","RAM Size":"2K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"31","Core Processor":"MSP430 CPUXV2","Package / Case":"38-TSSOP (0.240\\\", 6.10mm Width)","Product Status":"Active","Data Converters":"A/D 12x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR5859","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"38-TSSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.3586","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/662f6d7793fada84e8ff14acce90914f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How to program MSP430FR5859IDA?","answer":"Programming uses the MSP430 JTAG or Spy-Bi-Wire (SBW) interface, supported by TI's Code Composer Studio and IAR Embedded Workbench.
