Product details
Overview
MSP430F5247IRGCR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 64 KB flash, 8 KB RAM, four 16-bit timers (TA0/TA1/TA2/TB0), dual USCI modules (UART/IrDA/SPI/I²C), 10-bit ADC with 12 channels (10 external + 2 internal), comparator, RTC, and hardware multiplier. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and data loggers.
For engineers reviewing the MSP430F5247IRGCR datasheet, MSP430F5247IRGCR pinout, MSP430F5247IRGCR application, or MSP430F5247IRGCR equivalent, key selection criteria include LPM3 standby current (1.9 µA), 3.5 µs wake-up time, VQFN-64 package compatibility, and ADC channel count versus F5249/F5237 variants.
Technical Context
The MSP430F5247IRGCR implements a CPUXV2 core with constant generators and unified clock system including FLL, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz). Its power management integrates an on-chip LDO with programmable core voltage and brownout detection.
Peripherals are mapped via port mapping control (P4) and support flexible I/O configuration. The device uses three-channel DMA for efficient data movement between ADC, USCI, timers, and memory without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5249IRGCR | 128 KB flash, same peripherals and pinout - higher code capacity for complex firmware | Supports larger protocol stacks (e.g., full Modbus RTU + OTA update) without external memory | Select when firmware growth headroom or future feature expansion is required |
| MSP430F5237IRGCR | No ADC10_A module - identical flash/RAM/timers/USCI but lacks analog-to-digital conversion | Used in digital-only sensor systems (e.g., switch monitoring, pulse counting) where ADC is unnecessary | Select when analog sensing is not required and BOM cost reduction is prioritized |
Compared with MSP430F5249IRGCR, the MSP430F5247IRGCR offers balanced flash capacity for mid-complexity firmware while retaining full analog capability; versus MSP430F5237IRGCR, it adds essential ADC functionality for analog sensor integration without increasing package size or pin count.

FAQ
What is the maximum system clock frequency supported by the MSP430F5247IRGCR?
The MSP430F5247IRGCR supports up to 25 MHz system clock frequency using the FLL with XT2 crystal (up to 32 MHz) or internal DCO. This enables high-speed peripheral operation and fast interrupt response while maintaining ultra-low-power architecture benefits. The device achieves 290 µA/MHz active-mode current at 8 MHz, confirming scalable performance within its power envelope.
Does the MSP430F5247IRGCR include an integrated ADC, and what are its key specifications?
Yes, the MSP430F5247IRGCR includes a 10-bit ADC (ADC10_A) with 200 ksps sampling rate, 12 input channels (10 external, 2 internal), and built-in reference voltage sources. It supports sample-and-hold, window comparator mode, and hardware-triggered conversions synchronized to timers or USCI events - all confirmed in the SLAS897C datasheet Section 8.35–8.37.
What package type and pin count does the MSP430F5247IRGCR use?
The MSP430F5247IRGCR uses a 64-pin VQFN package (RGC variant), measuring 9 mm × 9 mm with an exposed thermal pad. Pinout matches MSP430F5249IRGCR and MSP430F5237IRGCR, enabling PCB layout reuse across the F524x/F523x RGC family - verified in Figure 7-1 of the SLAS897C datasheet.
How does the power management system of the MSP430F5247IRGCR reduce energy consumption in battery-operated devices?
The MSP430F5247IRGCR reduces energy consumption via multiple low-power modes: LPM3 draws just 1.9 µA with RTC active and full RAM retention, and LPM4 draws 1.1 µA with only supply supervisor enabled. Its integrated LDO allows dynamic VCORE scaling, and the 3.5 µs wake-up time minimizes transition overhead - collectively extending battery life in intermittent-sensing applications.
Which communication interfaces are available on the MSP430F5247IRGCR, and how are they implemented?
The MSP430F5247IRGCR provides two universal serial communication interfaces (USCI_A0/A1 and USCI_B0/B1). USCI_A supports UART (with auto-baud detection), IrDA, and SPI; USCI_B supports I²C and SPI. Each module has independent clock sources and control registers, allowing concurrent full-duplex UART and I²C operation - confirmed in Section 1 Features and Figure 4-1.
