The 92 KB program store accommodates a full MSP430 firmware image including a real-time kernel and LCD display driver; the 4 KB RAM handles stack and small data buffers without external SRAM. The integrated LCD controller drives segmented glass panels directly, eliminating the cost and board space of an external display driver IC. DMA moves data between peripherals and memory without CPU intervention, freeing the 8 MHz core for application code. Serial connectivity covers I2C, SPI, UART/USART, IrDA, and SCI — a single part can talk to I2C sensors, SPI flash, and a UART debug console over the same bus. ## Package, supply, and temperature grade Housed in a 100-LQFP package with a 14x14 mm body. The 0.50 mm pitch demands a 4-layer board for reliable fan-out of the inner rows; a 2-layer board will route only the perimeter pins. The internal oscillator starts from the supply rail without an external crystal, though the internal RC accuracy (±1% typical over temp) limits precision timing to baud-rate generation.","metaTitle":"MSP430F46161IPZR MCU, 16-bit 8 MHz, 92KB Flash, 100-LQFP","metaDescription":"Texas Instruments MSP430F46161IPZR, 16-bit MSP430 CPUX at 8 MHz, 92KB Flash, 4KB RAM, 80 I/O, LCD controller, -40 to 85°C, 100-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":"8MHz","Series":"MSP430x4xx","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"4K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, LCD, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"80","Core Processor":"MSP430 CPUX","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F46161","Program Memory Size":"92KB (92K x 8 + 256B)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.0014","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1fcea670b9343edbca2b2bc7659e99b7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F46161IPZR/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy MSP430F46161IPZR and how do I get a price?","answer":"The MSP430F46161IPZR is available to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
