The Texas Instruments MSP430FG4619IPZ is a 16-bit MSP430 CPUX microcontroller from the MSP430x4xx series, clocked at 8 MHz. It packs 120 KB of Flash program memory and 4 KB of RAM, with 80 general-purpose I/O lines brought out to a 100-pin LQFP (14x14 mm) package. The part integrates a 12-channel 12-bit ADC and two 12-bit DACs, an LCD driver, DMA controller, and a full set of serial interfaces including I²C, SPI, UART, IrDA, and LINbus. It operates from 1.8 V to 3.6 V and is rated for -40°C to 85°C, making it suitable for industrial sensor nodes, portable instrumentation, and mixed-signal control applications where a single-chip analog front-end is preferred over a separate converter chain.
8 MHz core — timing budget for mixed-signal tasks
The 8 MHz clock rate on the MSP430 CPUX core sets the instruction throughput for signal-processing and control loops.
120 KB Flash / 4 KB RAM — firmware and data buffer fit
The 120 KB Flash (organized as 120K x 8 plus 256 bytes) is sized for a moderate firmware image — enough for a real-time operating system kernel, communication stacks, and application logic for a data-logging or control node. The 4 KB RAM (4K x 8) is the working memory; it will hold stack, global variables, and a small circular buffer for ADC samples. If the application requires larger data arrays or double-buffered DMA transfers, the RAM budget needs careful accounting during firmware development.
On-chip data converters — one-chip analog front-end
The integrated 12-bit ADC with 12 input channels and dual 12-bit DACs cover the analog I/O needs of many instrumentation and sensor-conditioning designs.
Industrial temperature range and supply
Rated for -40°C to 85°C, this MCU fits outdoor telecom cabinets, factory-floor controllers, and automotive-cabin modules.
Package and I/O
The 100-LQFP (14x14 mm) package is a standard surface-mount footprint compatible with typical reflow profiles and inspection processes.
