MSP430F5438AIZCAT - 25MHz 256KB MCU | Texas Instruments
Référence : MSP430F5438AIZCAT ✗ Fin de vieMSP430F5438AIZCAT Présentation
What is a mixed-signal microcontroller? A mixed-signal microcontroller combines a digital processor core with analog or mixed-signal peripherals, allowing a single embedded device to measure real-world inputs and execute control logic. The MSP430 family belongs to the broader embedded-controller hierarchy: MCU, microprocessor, embedded semiconductor, and electronic component. In this MSP430F5438AIZCAT, the 16-bit CPUXV2 architecture is supported by flash, SRAM, serial interfaces, timers, direct memory access, and ADC resources.
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.

Applications typiques
MSP430F5438AIZCAT convient pour 6 applications: Industrial Sensor Acquisition, Low-Power Monitoring Node, UART Connected Control Board, SPI Data Acquisition System, I2C Sensor Hub, Data Logger.
Industrial Sensor Acquisition
The MSP430F5438AIZCAT fits industrial sensor acquisition because its verified feature set combines a 12-bit ADC, 25 MHz 16-bit CPU, 16 KB SRAM, and DMA. The MCU can acquire analog sensor channels and execute control logic while DMA reduces the processor burden for data movement. UART, SPI, and I2C provide paths to external sensors, gateways, and service interfaces. The design should confirm ADC input limits, sampling behavior, reference voltage, and electrical noise from the complete datasheet before setting the analog front end.
Recommandé
Low-Power Monitoring Node
For a low-power monitoring node, MSP430F5438AIZCAT provides 16 KB SRAM, 256 KB flash, and a 25 MHz CPU for local sampling, filtering, event handling, and data preparation. The mixed-signal resources allow an ADC-based measurement function without adding a separate controller. The verified extracts do not include sleep-current figures or wake-up timing, so battery-life calculations require the manufacturer datasheet. Firmware and power-domain decisions should be validated against the target board rather than inferred from CPU frequency.
Recommandé
UART Connected Control Board
MSP430F5438AIZCAT is suitable for a UART-connected control board because the verified TI product-page extract explicitly lists UART, SPI, and I2C alongside timers and DMA. The microcontroller can manage commands, sensor updates, and actuator sequencing while the 16 KB SRAM supports local buffering and 256 KB flash supports firmware storage. Exact UART instance availability, multiplexing, baud-rate limits, and I/O voltage levels must be checked against the target package and datasheet before assigning pins or designing the board.
Recommandé
SPI Data Acquisition System
The MSP430F5438AIZCAT can act as the controller for an SPI data-acquisition system because SPI is listed among its verified peripherals and the device provides DMA for efficient transfers. A suitable design can collect data from an external ADC, sensor, or memory device while the CPU handles configuration and processing. DMA helps reduce interrupt overhead, but channel mapping, maximum SPI rate, chip-select strategy, and pin multiplexing must be verified from the complete manufacturer documentation.
Recommandé
I2C Sensor Hub
MSP430F5438AIZCAT can serve as an I2C sensor hub because the verified feature list includes I2C and a 25 MHz CPU for coordinating measurements and local logic. The 12-bit ADC can provide an internal monitoring path, while 16 KB SRAM can hold short-term data for filtering or event buffering. Designers should confirm the number of I2C controllers, address behavior, electrical levels, pull-up requirements, and pin assignments in the full datasheet before connecting multiple sensors.
Recommandé
Data Logger
A compact data logger can use the MSP430F5438AIZCAT for sampling, time-based scheduling, buffering, and communications because the verified data identifies 256 KB flash, 16 KB SRAM, a 12-bit ADC, DMA, timers, and UART, SPI, and I2C. The MCU can collect sensor information locally and transfer it through a serial interface when connectivity is available. Flash endurance, retention, write timing, brownout behavior, and maximum logging rate are not provided in the supplied extracts and must be checked before production storage design.

Notes de conception
Treat the MSP430F5438AIZCAT as a fine-pitch BGA design and use only the manufacturer-provided 113-pin NFBGA footprint. Verify ball numbering, pad dimensions, solder-mask definition, and assembly land pattern against the current package drawing. The verified data identifies the package as 113-pin NFBGA measuring 7 x 7 mm, but it does not provide the ball map or recommended PCB layout; do not infer those details from a generic BGA footprint.
Confirm the target voltage rails, I/O levels, decoupling values, and power-up sequence from the complete manufacturer datasheet before PCB release. The supplied extracts identify the MCU and its 25 MHz, 256 KB flash, and 16 KB SRAM features but do not state supply limits or current consumption. Keep the regulator design and bypass network based on verified electrical requirements, and include measurement points for startup, steady-state, and sleep behavior if applicable.
Do not substitute a family-level MSP430F5438A reference for the orderable MSP430F5438AIZCAT without checking the complete ordering table. Package, pin/ball assignment, temperature grade, flash/RAM configuration, and lifecycle can vary by ordering suffix. The verified cross-reference results did not establish a confirmed drop-in replacement, so any alternate part requires a documented comparison of ballout, memory, CPU speed, peripherals, supply limits, and firmware target.
Informations de conformité
The supplied verified extracts do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown pending current manufacturer or distributor documentation.
