Product details
Overview
M430F5438AQZCARET from Texas Instruments is an ultralow-power 16-bit RISC microcontroller with 256 KB flash, 16 KB RAM, and extended temperature support (–40°C to 125°C). It integrates a 12-bit ADC (14 external + 2 internal channels), three 16-bit timers (TA0/TA1/TB0), four USCI modules (UART/I²C/SPI), hardware multiplier, DMA, RTC, and programmable LDO. It targets battery-powered portable measurement systems requiring long runtime and high analog integration.
For engineers reviewing the M430F5438AQZCARET datasheet, M430F5438AQZCARET pinout, M430F5438AQZCARET application, or M430F5438AQZCARET equivalent, key selection criteria include its –40°C to 125°C Q-temp qualification, 1.2 µA LPM3 standby current at 3.0 V, 3.5 µs wake-up time, 25-MHz max system clock, and 113-pin nFBGA (7 mm × 7 mm) package with 87 GPIOs.
Technical Context
The M430F5438AQZCARET implements a CPUXV2 core with constant generators for code efficiency and uses a digitally controlled oscillator (DCO) stabilized by an FLL loop. Its unified clock system supports multiple sources: 32-kHz XT1 crystal, up to 32-MHz XT2 crystal, internal VLO (10 kHz), and trimmed REFO (32.768 kHz).
Power management includes a fully integrated LDO with four programmable core voltage levels (PMMCOREVx = 0–3), supply voltage supervision (SVS/SVM), and five low-power modes (LPM0–LPM4.5). Peripheral integration follows TI's MSP430F5xx architecture, with memory-mapped registers, interrupt vector table at fixed addresses, and JTAG/Spy-Bi-Wire debug interface.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F6736AIPZ | Higher-integration metering SoC: 32-bit SD24 sigma-delta ADC, LCD controller, 3-phase metrology engine; 256 KB flash, same 113-pin nFBGA | Targeted specifically for polyphase energy meters; lacks general-purpose USCI_B3 and TB0 shadow register flexibility | Select when precision metrology and LCD drive are primary; not drop-in for general-purpose sensor control |
| MSP430FR5969IRGZT | Ferroelectric RAM (FRAM) instead of flash: 64 KB FRAM, 2 KB RAM, 12-bit ADC, same USCI/timer count; operates down to 1.8 V but rated only to 85°C | Superior write endurance (>10¹⁴ cycles) and near-zero write latency; unsuitable for extended temperature deployments | Select for high-data-logging-frequency applications where flash wear-out is a concern; verify thermal envelope compliance |
Compared with M430F5438AQZCARET, the MSP430F6736AIPZ adds metrology-specific peripherals at the cost of general-purpose I/O flexibility, while the MSP430FR5969IRGZT trades flash endurance and temperature range for FRAM's instant-write capability - making each suitable only for distinct system-level trade-offs.

FAQ
What is the maximum system clock frequency supported by the M430F5438AQZCARET?
The M430F5438AQZCARET supports a maximum system clock (MCLK) frequency of 25 MHz, achievable when PMMCOREVx = 3 and VCC ≥ 2.4 V. This is enabled by the integrated FLL-controlled DCO and verified across the full –40°C to 125°C operating range. The M430F5438AQZCARET datasheet specifies derating curves in Figure 7-2 showing frequency vs. supply voltage dependencies for each PMMCOREVx setting.
Does the M430F5438AQZCARET support external crystal oscillators above 32 kHz?
Yes, the M430F5438AQZCARET supports high-frequency crystals up to 32 MHz via the XT2 oscillator circuit (pins P5.2/XT2IN and P5.3/XT2OUT). However, TI documentation explicitly states that crystal operation above 85°C is not ensured for both 32-kHz and high-frequency crystals - so XT2 use is restricted to ≤85°C ambient in thermally demanding applications.
How many general-purpose I/O pins does the M430F5438AQZCARET provide?
The M430F5438AQZCARET provides up to 87 general-purpose I/O pins across ports P1–P11 and PJ, as confirmed in the functional block diagram and pin configuration tables. All I/Os support interrupt capability, configurable pull-up/down resistors, and Schmitt-trigger inputs. The 113-pin nFBGA package allocates 26 pins as reserved or power/ground, leaving 87 dedicated for user I/O functionality.
What ADC reference options are available on the M430F5438AQZCARET?
The M430F5438AQZCARET ADC supports three reference configurations: internal 2.5-V reference (REFO), external reference applied to P5.0/VREF+, or AVCC as reference. P5.0 and P5.1 serve dual roles as analog inputs A8/A9 and reference terminals (VREF+/VREF−), enabling flexible precision measurement setups without external reference ICs in most designs.
Is the M430F5438AQZCARET pin-compatible with other members of the MSP430F5438A family?
Yes, the M430F5438AQZCARET shares identical pinout and electrical characteristics with M430F5438AMZCARET, M430F5438AQGCARET, and M430F5438AMGCARET - all use the same 113-pin nFBGA (ZCA/GCA) package and default signal mapping. Differences are limited to temperature grade (Q vs M) and ball finish (SnAgCu vs SnPb), not pin function or layout.
