Product details

Overview

MSP430FR5738IYQDR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 16KB nonvolatile memory, 24-MHz CPU, 10-bit ADC (6 external channels), and 10-channel analog comparator. It operates from 2 V to 3.6 V across –40°C to 85°C and targets battery-powered sensor nodes requiring fast write endurance and RTC-based data logging.

For engineers reviewing the MSP430FR5738IYQDR datasheet, MSP430FR5738IYQDR pinout, MSP430FR5738IYQDR application, or MSP430FR5738IYQDR equivalent, key selection criteria include FRAM write cycle endurance (10¹⁵), LPM3.5 RTC current (1.5 µA), eUSCI_A0/A1 UART/IrDA/SPI support, and DSBGA-24 package footprint constraints.

Technical Context

The MSP430FR5738IYQDR implements the MSP430xV2 CPU core with three low-power modes enabled by integrated SVS and BOR. Its FRAM memory subsystem includes built-in ECC and MPU for code/data integrity in safety-critical sensing applications.

Peripherals are managed via three eUSCI modules: eUSCI_A0 and A1 support UART with auto-baud detection and IrDA encoding/decoding; eUSCI_B0 supports I²C with multi-slave addressing and SPI. The 10-bit ADC operates at 200 ksps with internal reference and sample-and-hold.

FAQ

What is the maximum operating frequency of the MSP430FR5738IYQDR?

The MSP430FR5738IYQDR supports a maximum system clock frequency of 24 MHz, achieved via its factory-trimmed DCO oscillator or external HFXT crystal. This frequency enables real-time signal processing while maintaining sub-100 µA/MHz active-mode current efficiency, making it suitable for responsive sensor fusion tasks without compromising battery life.

Does the MSP430FR5738IYQDR support hardware UART with automatic baud-rate detection?

Yes, the MSP430FR5738IYQDR supports automatic baud-rate detection in UART mode through its eUSCI_A0 and eUSCI_A1 modules. This feature allows robust communication with variable-speed hosts (e.g., legacy modems or field devices) without pre-configured baud settings, reducing integration effort in heterogeneous industrial networks.

How many ADC input channels does the MSP430FR5738IYQDR have, and what is their resolution?

The MSP430FR5738IYQDR integrates a 10-bit SAR ADC with six external analog input channels (A0–A5) plus two internal channels (temperature sensor and VMID). Its 200 ksps sampling rate and internal reference ensure accurate, low-power acquisition for environmental and condition-monitoring sensors.

What is the FRAM endurance specification for the MSP430FR5738IYQDR?

The MSP430FR5738IYQDR features 16 KB of FRAM with 10¹⁵ write cycle endurance - orders of magnitude higher than flash memory. This enables continuous data logging (e.g., hourly sensor readings) for over 100,000 years without wear-out concerns, critical for unattended infrastructure monitoring deployments.

Is the MSP430FR5738IYQDR pin-compatible with other devices in the MSP430FR573x family?

No, the MSP430FR5738IYQDR uses the 24-ball DSBGA (YQD) package, which is not pin-compatible with RGE (VQFN-24), PW (TSSOP-28), or RHA (VQFN-40) variants. Pin mapping differs significantly across packages; migration requires PCB redesign and signal validation per TI's Signal Descriptions table for YQD.
