At this speed the internal flash needs zero wait states up to about 8 MHz; above that, one wait state is required or the first instruction fetch after a branch will hard-fault. Plan the clock tree accordingly if you push the DCO or an external oscillator to the full 16 MHz. ## 60 KB Flash and 2.5 KB RAM — firmware and data budget Program memory is 60 KB of FLASH (60K x 8 plus 256 bytes of information memory). RAM is 2.5K x 8. That Flash budget fits a moderate sensor-fusion or LCD-driven control loop; the RAM is tight for large frame buffers, so offload data to the Flash information memory or an external serial EEPROM over I²C or SPI. On-chip peripherals include a brown-out reset, power-on reset, LCD driver (up to 160 segments), PWM timer, and watchdog timer. ## 72 I/O and 4x16-bit ADC — sensor interface capacity With 72 general-purpose I/O pins and a 4-channel 16-bit sigma-delta ADC, this part can handle multiple analog sensors alongside a segmented LCD display. The 100-LQFP (14x14 mm) package gives enough breakout for a mixed-signal board without resorting to a finer-pitch BGA.","metaTitle":"MSP430F4794IPZ 16-bit MCU, 60KB Flash, 16 MHz, 100-LQFP","metaDescription":"Texas Instruments MSP430F4794IPZ 16-bit MCU with 60KB Flash, 2.5K x 8 RAM, 16 MHz core, 72 I/O, LCD driver, industrial temp -40°C~85°C.","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":"MSP430x4xx","Package":"Tray","RAM Size":"2.5K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, LCD, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"72","Core Processor":"MSP430 CPU16","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"A/D 4x16b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F4794","Program Memory Size":"60KB (60K 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":"$9.9717","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cdba3a4c01690c941d2905afb361b46a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F4794IPZ/alternatives.json"},"ai":{"faq":[{"question":"Does MSP430F4794IPZ have an internal oscillator?","answer":"Yes, the MSP430F4794IPZ includes an internal oscillator, so it can run without an external crystal or clock source for many applications."},{"question":"What are the alternatives to MSP430F4794IPZ?","answer":"Within the MSP430x4xx family, the MSP430F4793 is a close pin-compatible alternative with the same 100-LQFP footprint and peripheral set, but with 48 KB Flash instead of 60 KB.
