The supply range is 2.4V to 3.6V, an internal oscillator supports low-cost clocking, and the part supports JTAG and Spy-Bi-Wire (2-wire JTAG) in-system programming and debug. Technically, the device combines a 16-bit RISC core, on-chip Flash, on-chip SRAM, and a flexible clock system with multiple internal DCO and VLO sources plus external crystal support. The DMA engine offloads peripheral-to-memory transfers, allowing the CPU to remain in a low-power mode during data acquisition - a key enabler for battery-powered sensor nodes. Typical applications include portable instrumentation, energy-harvesting sensor nodes, smart metering, motor control, low-end medical devices, and battery-powered industrial sensor hubs where the 16-bit HRT improves timing resolution. The TSSOP-38 footprint is friendly to hand-solder prototypes and compact production PCBs alike. When designing with the MSP430F5152, leave adequate ground copper near the exposed pad area to support the device's low-noise analog blocks, and ensure the AVCC/AVSS pair is filtered with a ferrite bead if the ADC and digital I/O coexist on the same rail.

The verified product data identifies a maximum CPU frequency of 25 MHz, 256 KB of flash organized as 256K x 8, and 16 KB of SRAM. Its listed peripherals include a 12-bit ADC, DMA, UART, SPI, I2C, timer resources, and a hardware multiplier. This combination makes the MCU suitable for applications requiring moderate computation, data acquisition, and multiple serial interfaces without relying on a separate analog front end. The part is identified by Texas Instruments under the MSP430F5438A family and is supplied in a 113-pin NFBGA package. The package is a surface-mount ball-grid-array format, with a stated size of 7 x 7 mm. The exact pin names, voltage limits, temperature range, ADC performance, clock options, and power characteristics are not present in the supplied verified extracts and therefore require confirmation from the manufacturer datasheet before schematic or PCB sign-off. Typical use cases include industrial sensor acquisition, low-power monitoring nodes, UART, SPI, or I2C-connected equipment, data loggers, actuator control, and compact embedded controllers. The MCU can supervise several digital peripherals while its ADC supports analog measurements. Designers should define the required serial interfaces and memory allocation first, then verify timing and electrical details against the complete datasheet. For a new design, confirm the MSP430F5438AIZCAT pin assignment, BGA ball map, power sequencing, decoupling requirements, and maximum operating conditions before layout. A drop-in alternative should not be selected from a family name alone; package, ballout, clock rating, memory, peripheral set, and firmware assumptions must all match. This page distinguishes verified information from missing technical parameters rather than estimating them. This page consolidates the verified distributor and manufacturer extracts for the MSP430F5438AIZCAT, including memory, CPU speed, package, major peripherals, sourcing context, and application guidance. Pricing, complete pinout, compliance status, lifecycle detail, and validated substitutes should be confirmed from current manufacturer or distributor documentation before purchase or production release.

MSP430F5438AIZQWR - 25MHz 256KB MCU | Texas Instruments

The Texas Instruments MSP430F5438AIZQWR is a 25 MHz, 16-bit mixed-signal microcontroller with 256 KB of flash memory, 16 KB of SRAM, and a 12-bit ADC in a 113-ball Microstar Junior BGA package. It integrates DMA, UART, SPI, I2C, timers, and a hardware multiplier for compact embedded control and sensor-processing designs. A mixed-signal microcontroller combines a digital processor core with peripherals designed to acquire and process analog signals. The MSP430F5438AIZQWR belongs to the MSP430 family of ultra-low-power 16-bit RISC microcontrollers, where CPU processing, communication, timing, and data acquisition are integrated into one device. This makes it suitable for embedded systems that require local sensing, control, and serial communications while keeping component count low. The device provides 256 KB of flash, 16 KB of SRAM, a 25 MHz clock, and a high-performance 12-bit ADC. Its communication peripherals include UART, SPI, and I2C, while DMA supports efficient transfers without repeatedly involving the CPU. The integrated hardware multiplier accelerates suitable arithmetic operations, and three 16-bit timers support periodic events, timing, and control-loop functions. These peripherals make the MCU appropriate for industrial instrumentation, data acquisition, building automation, and low-power embedded control. The MSP430 architecture supports low-power-oriented embedded designs, particularly when the firmware can use its timers, interrupts, and serial interfaces to avoid continuous processor activity. Peripheral integration reduces the need for separate interface or conversion ICs, while DMA can improve responsiveness when moving ADC, communication, or memory data. The 113-ball package provides substantial I/O connectivity, but its fine-pitch BGA construction requires careful PCB layout, inspection, and assembly capability. Typical applications include sensor nodes, industrial measurement systems, building-control equipment, portable instruments, communication modules, and embedded data loggers. UART, SPI, and I2C allow connection to sensors, transceivers, displays, storage devices, and external controllers. The 12-bit ADC supports analog measurement, while DMA and timers help implement responsive acquisition and control tasks. When designing around this MCU, validate the complete 113-ball pinout and power requirements against the manufacturer datasheet before layout. Confirm that the PCB assembly process supports the package, provide suitable decoupling and analog routing around the ADC, and verify all unused BGA balls according to the device guidelines. Pricing and availability should be checked for the exact orderable MPN. This page combines verified manufacturer and distributor information with package, application, comparison, and design guidance intended to make component selection more practical. It is not a substitute for the complete datasheet, which remains the authoritative source for electrical limits, timing, pin definitions, and errata.
