MSP430F5438AIPZ جائزہ

The Texas Instruments MSP430F5438AIPZ is a 16-bit RISC mixed-signal microcontroller built on the MSP430 CPUXV2 core, delivering up to 25 MHz performance with 256 KB of embedded Flash and 16 KB of SRAM, packaged in a 100-pin LQFP (14x14 mm). It integrates a 12-bit SAR ADC with 14 channels, a 32-bit hardware multiplier, a 4-channel DMA controller, and four universal serial communication interfaces that support UART, SPI, and I2C protocols.

An MCU (Microcontroller Unit) is a single-chip computer that integrates a CPU, memory, and programmable peripherals around a common bus. The MSP430 is a 16-bit ultra-low-power MCU family from Texas Instruments, positioned in the hierarchy as: microcontroller → mixed-signal MCU → ultra-low-power MCU → embedded processor → semiconductor. The MSP430 architecture pairs a 16-bit RISC CPU with constant generators and 16-bit registers, optimized for portable measurement applications where battery life is critical.

Key features of the MSP430F5438AIPZ include five low-power modes (LPM0-LPM4) that draw as little as microamp-level standby currents, an on-chip real-time clock (RTC) module with a separate supply pin for calendar functions in battery-backed systems, and a sophisticated timer subsystem (Timer_A and Timer_B) supporting PWM, capture, and compare. The integrated DMA reduces CPU wake events by autonomously servicing peripherals and buffering ADC samples.

The device supports JTAG and Spy-Bi-Wire two-wire debug interfaces for in-system programming and debugging without consuming a dedicated UART pin set. Its 87 configurable GPIO pins and 14 ADC channels suit mixed-signal sensing. The architecture, combined with extensive low-power modes, is optimized to achieve extended battery life in portable measurement applications such as wireless sensor nodes, energy-harvesting instrumentation, smart meters, and human-interface devices.

Typical end applications include wireless sensor networks (paired with sub-1 GHz or 2.4 GHz transceivers), industrial data loggers, e-metering, portable medical instruments, and human-machine interface panels. Designers commonly pair this MCU with the CC1120 or CC2530 RF transceiver for low-power IoT nodes.

When designing with this part, place a 100 nF decoupling capacitor as close as possible to each AVCC and DVCC pin pair and provide a 1 µF bulk capacitor on the main supply rail. Use the Spy-Bi-Wire interface for a debug footprint that occupies only two MCU pins, freeing the rest for user I/O.

Wireless Sensor Network Node

The MSP430F5438AIPZ is well matched to wireless sensor nodes (WSN) where idle current dominates the energy budget. Its LPM3 sleep current of roughly 2.1 uA keeps total system consumption minimal when the radio is off, while the 256 KB Flash accommodates a SimpliciTI or proprietary 802.15.4 stack and application code. The integrated 4-channel DMA offloads packet buffering from the CPU, letting the CPU remain in LPM until the radio interrupt wakes it. Paired with the CC1120 sub-1 GHz transceiver, the node achieves years of battery life on two AA cells in typical metering applications.

It includes electrical specifications, pin descriptions, peripheral registers, and reference code examples.
What is the pinout of MSP430F5438AIPZ?
The MSP430F5438AIPZ is housed in a 100-pin LQFP package measuring 14x14 mm. Pin 1 is identified by a top-left dot marker and the package is numbered counter-clockwise. The pinout assigns power pins (DVCC/AVCC) in pairs across the package, with analog pins grouped together for clean ADC reference routing. The full 100-pin assignment is shown in the datasheet pinout diagram; this product page also provides a complete pin-by-pin table.
What is the difference between MSP430F5438AIPZ and MSP430F5438IPZ?
The MSP430F5438AIPZ is the 'A' revision silicon, rated to 25 MHz, while the older MSP430F5438IPZ (without the 'A') is rated to 18 MHz. Both parts share the same 256 KB Flash, 16 KB SRAM, 12-bit ADC, and 100-pin LQFP package, making them nominally drop-in compatible. However, firmware timing paths and CPU cycle accounting must be re-validated if migrating between the two, since the higher maximum clock on the 'A' revision is the headline difference per the manufacturer datasheet.
How much does MSP430F5438AIPZ cost in 100-piece quantity?
As of 2026-10-21, the MSP430F5438AIPZ is listed at approximately $11.07 in 100-piece quantity from authorized distributors. Single-piece pricing is around $13.85 and 1,000-piece reels drop to roughly $8.95. Pricing fluctuates with availability; check DigiKey and Mouser for current stock and lead time before committing to a BOM.
Is MSP430F5438AIPZ in stock at distributors?
As of 2026-10-21, the MSP430F5438AIPZ is listed as 'ships today' on DigiKey and is available from Mouser with stock. The part is in active production status per the TI product page, meaning lead times are short and no end-of-life notice is currently published. For larger production volumes, request a quote directly from Texas Instruments.
What are the key specifications of MSP430F5438AIPZ that engineers should know?
The MSP430F5438AIPZ integrates a 25 MHz 16-bit MSP430 CPUXV2 core, 256 KB Flash, 16 KB SRAM, 12-bit SAR ADC with 14 channels, 4-channel DMA, 32-bit hardware multiplier, four USCI serial interfaces supporting UART/SPI/I2C, real-time clock with VBAT backup supply, and 87 GPIO. It is packaged in a 100-pin LQFP, operates from 1.8 V to 3.6 V, and supports JTAG plus 2-wire Spy-Bi-Wire debug. The architecture targets portable measurement applications with five low-power modes down to sub-µA standby currents.
Can MSP430F5438AIPZ be replaced by another same-package MSP430 device?
Yes. Within the MSP430F5xx family, several same-package 100-pin LQFP devices share the same pinout and can replace the MSP430F5438AIPZ with minor changes to firmware targeting memory size. The MSP430F5438APZ, MSP430F5436AIPZ, MSP430F5435AIPZ, and automotive-grade MSP430F5438AIPZQ1 share the same footprint. Migration requires verifying that the alternate part has equal or greater Flash and SRAM to the original 256 KB / 16 KB.
What is the best TI equivalent for MSP430F5438AIPZ?
The best same-package TI equivalents are the MSP430F5436AIPZ (192 KB Flash / 16 KB SRAM), MSP430F5435AIPZ (256 KB Flash / 16 KB SRAM), and MSP430F5438AIPZQ1 (automotive AEC-Q100 qualified version). All three share the 100-pin LQFP (14x14 mm) package and identical pin assignments. Choose the F5436A for lower cost when 192 KB is sufficient; choose the F5438A-Q1 for automotive applications requiring AEC-Q100 qualification.
Is MSP430F5438AIPZ suitable for wireless sensor networks?
Yes. The MSP430F5438AIPZ is well suited to wireless sensor network nodes because its low-power modes (LPM3, LPM4) draw only a few microamps, allowing a battery-powered sensor and sub-1 GHz transceiver like the CC1120 or CC2530 to operate for years on a single cell. The 256 KB Flash is enough to hold a SimpliciTI or proprietary RF protocol stack plus application logic, and the integrated DMA wakes the CPU only when the radio has data ready.
What is the lead time for MSP430F5438AIPZ?
As of 2026-10-21, the MSP430F5438AIPZ ships from stock at major distributors (DigiKey shows 'ships today'), and the lead time for production quantities is generally 6 to 12 weeks from TI directly. Because the device is in active production with no EOL notice published, lead times for catalog distributor purchases typically remain under one week. For large-volume orders, contacting a TI authorized distributor is recommended.
Does MSP430F5438AIPZ support low-power standby modes?
Yes. The MSP430F5438AIPZ supports five low-power modes, LPM0 through LPM4, with standby currents as low as sub-µA when the CPU is halted and most peripherals are gated off. The real-time clock can continue running from the VBAT backup supply pin, allowing time-of-day functions to continue while the main DVCC is powered down. These low-power modes are the defining feature that makes the part attractive for battery-powered applications.
What debug interface does MSP430F5438AIPZ use?
The MSP430F5438AIPZ supports both full JTAG (4-wire) debug and the proprietary 2-wire Spy-Bi-Wire interface. Spy-Bi-Wire uses only the TEST and RST pins to provide programming and emulation, leaving the standard JTAG pins free for user GPIO or additional functions. Most modern MSP430 debuggers including the TI MSP-FET and LaunchPad onboard debug use Spy-Bi-Wire by default.
What package type and size is MSP430F5438AIPZ?
The MSP430F5438AIPZ is housed in a 100-pin LQFP (Low-profile Quad Flat Pack) measuring 14x14 mm with a pin pitch of 0.5 mm. The Z suffix in the part number designates this LQFP package; the I suffix indicates the industrial -40 C to +85 C operating temperature range. The LQFP-100 footprint is shared across many MSP430F5xx devices, enabling PCB layout reuse for migration within the family.

انتخاب کی گائیڈ

Choose the MSP430F5438AIPZ for portable sensing applications that need 256 KB Flash, 16 KB SRAM, 14 ADC channels, and ultra-low-power sleep modes below 2 µA. The part is best-fit for wireless sensor nodes, smart meters, and battery-powered industrial data loggers. Choose the MSP430F5436AIPZ if 192 KB Flash is sufficient and BOM cost is a concern. Choose the MSP430F5438AIPZQ1 for AEC-Q100 automotive applications. Choose the MSP430F6638IPZ if you also need an integrated LCD driver (it adds 18 KB SRAM but runs only to 18 MHz and is a cross-package alternative only when the LCD peripheral is required). All six same-package parts share the identical 100-LQFP (14x14) footprint, easing BOM changes without PCB rework.

ڈیزائن نوٹس

Place one 100 nF decoupling capacitor as close as possible to each DVCC/AVCC pin pair and add a single 1 µF to 10 µF bulk capacitor on the main supply rail. The MSP430F5438AIPZ supports five low-power modes; LPM3 (RTC active) draws ~1.5 µA and LPM4 (full shutdown with wake from RST/NMI) drops into the tens of nA range. Exit from LPM3 via any enabled interrupt source in single-digit microseconds. Estimated: idle currents from datasheet typical curves, supply decoupling per TI recommended layout.

The 100-pin LQFP-100 footprint uses a 0.5 mm pin pitch and 14x14 mm body. Provide at least 0.5 mm clearance between pads and 0.2 mm trace width clearance to allow for hand-rework. Avoid routing long analog (P5/P7/P8) traces alongside digital switching lines. Keep the AVSS and DVSS loops separate and tie them to a single ground point under the MCU. Place the 32.768 kHz crystal between XIN/XOUT within 5 mm and shield it with a ground guard ring routed around the traces.

Do not assume a portable battery source will stay above the brownout reset threshold during high-current radio bursts. Add a 10 µF tantalum or ceramic bulk capacitor near the DVCC pins so that transmit surges do not cause spurious resets. When migrating from MSP430F5438 (non-A) to MSP430F5438A, re-time any cycle-sensitive delay loops since the CPU maximum frequency changed from 18 MHz to 25 MHz - the loop will run ~39% faster than expected. Finally, set unused I/O pins to output-low to avoid parasitic supply leakage.
