Texas Instruments MSP430F5524IRGCT

Overview

MSP430F5524IRGCT from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller with integrated USB 2.0 PHY, 64KB flash, 4KB+2KB RAM, 47 GPIO pins, and a 12-bit ADC with 12 input channels (10 external, 2 internal). It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and USB-connected data loggers requiring fast wake-up (3.5 µs) and sub-2 µA standby current.

For engineers reviewing the MSP430F5524IRGCT datasheet, MSP430F5524IRGCT pinout, MSP430F5524IRGCT application, or MSP430F5524IRGCT equivalent, key selection criteria include USB 2.0 endpoint count (8), RTC support in LPM3, ADC autoscan capability, VQFN-64 package thermal performance, and compatibility with MSP430Ware™ development tools.

Technical Context

The MSP430F5524IRGCT implements a 16-bit RISC CPU with constant generators and an integrated digitally controlled oscillator (DCO), enabling deterministic 3.5 µs wake-up from LPM3. Its unified clock system supports FLL stabilization, dual crystal oscillators (XT1 for 32 kHz, XT2 up to 32 MHz), and low-power internal sources (VLO, REFO).

Power management includes a programmable LDO core regulator, supply voltage supervisor (SVS), brownout reset (BOR), and four low-power modes (LPM0–LPM4.5). Peripheral integration features three DMA channels, hardware multiplier (MPY32), two USCI modules (UART/IrDA/SPI/I²C), and full-speed USB with integrated 3.3-V/1.8-V power system and USB-PLL.

FAQ

What is the maximum system clock frequency supported by the MSP430F5524IRGCT?

The MSP430F5524IRGCT supports a maximum system clock frequency of 25 MHz, achieved via the FLL-controlled DCO using XT2 (high-frequency crystal) or internal reference sources. This frequency is validated across the full operating voltage range (1.8 V to 3.6 V) and ambient temperature (–40°C to 85°C), enabling deterministic real-time processing for time-critical sensor sampling and USB transaction handling in the MSP430F5524IRGCT.

Does the MSP430F5524IRGCT include an integrated USB physical layer (PHY)?

Yes, the MSP430F5524IRGCT integrates a full-speed USB 2.0 PHY with on-die termination, ESD protection, and differential driver/receiver circuitry. It also includes an integrated USB power system generating both 3.3-V and 1.8-V supplies for the PHY and internal logic, eliminating external regulators or level shifters - a confirmed feature documented in the SLAS590P datasheet Section 3 and Figure 4-2.

How many analog input channels does the 12-bit ADC in the MSP430F5524IRGCT support?

The MSP430F5524IRGCT's ADC12_A module supports 12 total input channels: 10 external analog inputs (A0–A9) and 2 internal sources (temperature sensor and V_REF/2). This configuration is explicitly defined in the functional block diagram (Figure 4-2) and Section 3 of the SLAS590P datasheet, distinguishing it from higher-pin-count variants like the MSP430F5529 that offer 16 channels.

What low-power mode current is specified for the MSP430F5524IRGCT in standby (LPM3) with RTC enabled?

The MSP430F5524IRGCT draws 1.9 µA typical current in LPM3 mode at 3.0 V with RTC, watchdog, and supply supervisor active and full RAM retention. This value is measured under standard conditions (25°C, 3.0 V, 32.768-kHz crystal) and is specified in Section 1 (Features) and Table 8.5 of the SLAS590P datasheet - confirming its suitability for decade-scale battery operation in time-stamped sensor applications.

Is the MSP430F5524IRGCT pin-compatible with other devices in the MSP430F55xx family?

The MSP430F5524IRGCT shares the VQFN-64 (RGC) package footprint and pinout with MSP430F5528IRGC, MSP430F5526IRGC, and MSP430F5522IRGC, as confirmed in Figures 4-2 and 4-4 of the SLAS590P datasheet. All RGC-packaged F55xx devices use identical signal assignments on P1–P6 ports, enabling PCB reuse across memory- and feature-tier variants within this package group.
