Product details
Overview
MSP430F5324IRGCT from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 64 KB flash, 6 KB RAM, integrated 3.3-V LDO, 12-bit ADC (10 external + 2 internal channels), two USCI modules (UART/IrDA/SPI/I²C), four 16-bit timers (TA0/TA1/TA2/TB0), RTC, hardware multiplier, and DMA - designed for battery-powered sensor systems and data loggers.
For engineers reviewing the MSP430F5324IRGCT datasheet, MSP430F5324IRGCT pinout, MSP430F5324IRGCT application, or MSP430F5324IRGCT equivalent, key selection criteria include standby current (1.9 µA in LPM3), wake-up time (3.5 µs), 47 I/O pins in VQFN-64, and compatibility with TI's MSP430F5xx toolchain and development ecosystem.
Technical Context
The MSP430F5324IRGCT implements a CPUXV2 core with constant generators and 16-bit registers for optimized code density. Its unified clock system integrates FLL-based frequency stabilization, dual crystal oscillators (XT1 up to 32 kHz, XT2 up to 32 MHz), and low-power internal sources (VLO, REFO).
Power management includes a programmable LDO core regulator, supply voltage supervision (SVM/SVS), brownout reset, and five low-power modes (LPM0–LPM4.5) with full RAM retention down to 0.18 µA in shutdown mode.

FAQ
What is the maximum system clock frequency supported by the MSP430F5324IRGCT?
The MSP430F5324IRGCT supports a maximum system clock (MCLK) frequency of 25 MHz, achieved using the FLL-controlled DCO with XT2 crystal input (up to 32 MHz) or internal reference. This enables high-speed ADC sampling at 200 ksps and fast UART baud rates without external PLL circuitry. The MSP430F5324IRGCT datasheet specifies timing parameters validated up to this frequency under recommended operating conditions.
Does the MSP430F5324IRGCT include an integrated DC-DC converter?
No, the MSP430F5324IRGCT does not include a DC-DC converter. It features an integrated low-dropout (LDO) regulator that generates a stable 3.3-V core supply (VCORE) from a 3.3-V ±10% input on LDOI. The LDO provides low-noise power for digital logic but lacks switching efficiency - users requiring higher efficiency must add an external DC-DC converter upstream of LDOI.
How many external analog input channels does the ADC12_A module support on the MSP430F5324IRGCT?
The ADC12_A module on the MSP430F5324IRGCT supports 10 external analog input channels (A0–A9), plus two internal channels (temperature sensor and VREF+/2). This matches the device comparison table in the SLAS678G datasheet and is confirmed by the functional block diagram for RGC-packaged variants. Channel mapping is fixed per port pin (e.g., P6.0 = A0, P6.1 = A1).
Is the MSP430F5324IRGCT pin-compatible with the MSP430F5329IPN?
No, the MSP430F5324IRGCT is not pin-compatible with the MSP430F5329IPN. The MSP430F5324IRGCT uses a 64-pin VQFN (RGC) package with 47 I/O pins, while the MSP430F5329IPN uses an 80-pin LQFP (PN) package with 63 I/O pins and different pin assignments. The functional block diagrams and pin diagrams in sections 4 and 7.2 of the datasheet confirm distinct signal layouts and package footprints.
What debug interface does the MSP430F5324IRGCT support?
The MSP430F5324IRGCT supports the Spy-Bi-Wire (SBW) interface via the RST/NMI/SBWTDIO and TEST/SBWTCK pins, providing full JTAG-equivalent debugging capability with only two wires. This interface is used by TI's MSP-FET and compatible tools for flash programming, breakpoint setting, and real-time variable inspection. No external level shifters or adapters are required for standard 3.3-V SBW operation.
