Product details
Overview
MSP430FR5738IYQDT from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 16KB ferroelectric RAM (FRAM), 1KB SRAM, 24-MHz system clock, 6-channel 10-bit ADC, 10-channel analog comparator, and dual eUSCI modules supporting UART, SPI, and I²C. It operates from 2 V to 3.6 V across –40°C to 85°C and targets battery-powered sensor nodes and energy-harvesting systems.
For engineers reviewing the MSP430FR5738IYQDT datasheet, MSP430FR5738IYQDT pinout, MSP430FR5738IYQDT application, or MSP430FR5738IYQDT equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), LPM3.5 RTC current (1.5 µA), integrated hardware multiplier, DMA support, and DSBGA-24 package footprint for space-constrained designs.
Technical Context
The MSP430FR5738IYQDT implements a 16-bit CPUXV2 core with seven low-power modes, including LPM4.5 (0.32 µA shutdown). Its FRAM memory replaces both flash and RAM, enabling instant nonvolatile writes without erase cycles and eliminating wear leveling overhead.
Peripherals include two eUSCI_A modules (UART/IrDA/SPI) and one eUSCI_B module (I²C/SPI), three 16-bit timers (Timer_A ×2, Timer_B ×1), RTC with calendar/alarm, 32-bit hardware multiplier, and 16-channel comparator with programmable hysteresis - all directly accessible via memory-mapped registers and configurable through dedicated control registers.

FAQ
What is the maximum system clock frequency supported by the MSP430FR5738IYQDT?
The MSP430FR5738IYQDT supports a maximum system clock frequency of 24 MHz, achieved via its factory-trimmed DCO oscillator or external HFXT crystal. This enables real-time processing of sensor data and fast FRAM writes while maintaining ultra-low active-mode current (81.4 µA/MHz typical). The CPUXV2 architecture ensures deterministic execution at this rate across the full operating voltage range (2.0 V to 3.6 V).
Does the MSP430FR5738IYQDT include hardware encryption or secure boot features?
No, the MSP430FR5738IYQDT does not include hardware encryption accelerators or secure boot circuitry. It relies on software-based security implementations and external secure elements for cryptographic operations. Its Memory Protection Unit (MPU) provides basic code/data isolation, but no AES, SHA, or TRNG peripherals are integrated - consistent with its focus on ultra-low-power sensing rather than secure communications.
How many I/O pins does the MSP430FR5738IYQDT provide in its DSBGA-24 package?
The MSP430FR5738IYQDT in the YQD (DSBGA-24) package provides 17 usable digital I/O pins, including P1.0–P1.5, PJ.0–PJ.3, P2.0–P2.5, and P2.7. Power (DVCC/DVSS/AVCC/AVSS), reset/debug (RST/NMI/SBWTDIO, TEST/SBWTCK), and oscillator (PJ.4/XIN, PJ.5/XOUT) pins are dedicated and not counted as general-purpose I/O. All 17 support interrupt and wake-up from LPMx.5 modes.
Can the MSP430FR5738IYQDT operate from a single 1.8-V supply?
No, the MSP430FR5738IYQDT requires a minimum supply voltage of 2.0 V and cannot operate reliably at 1.8 V. Its absolute maximum ratings specify 1.8 V as the lower limit for storage, but recommended operating conditions mandate 2.0 V to 3.6 V for functional operation. Attempting 1.8-V operation risks undefined behavior, failed FRAM writes, and unstable oscillator startup - especially below 2.0 V across temperature.
Is the MSP430FR5738IYQDT pin-compatible with other devices in the MSP430FR573x family?
No, the MSP430FR5738IYQDT is not pin-compatible with other MSP430FR573x variants due to its unique DSBGA-24 (YQD) package. While functionally identical to MSP430FR5738PW (TSSOP-28) and MSP430FR5738RGE (VQFN-24), the YQD ball map differs - particularly in power pin placement and peripheral signal assignment. Board redesign is required when migrating between packages, even within the same FR5738 variant.
