Product details
Overview
MSP430F5528IRGCT from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with integrated USB 2.0 PHY, 12-bit ADC (12-channel), four 16-bit timers, two USCI modules (UART/IrDA/SPI/I²C), RTC, and hardware multiplier. It operates from 1.8 V to 3.6 V and delivers 290 µA/MHz active current at 8 MHz (flash execution), enabling battery-powered sensor nodes and USB-connected data loggers.
For engineers reviewing the MSP430F5528IRGCT datasheet, MSP430F5528IRGCT pinout, MSP430F5528IRGCT application, or MSP430F5528IRGCT equivalent, key selection considerations include its 64-pin VQFN package, 47 GPIOs, USB-capable peripheral set, LPM3 standby current of 1.9 µA, and compatibility with TI's MSP430Ware™ and LaunchPad™ ecosystem for rapid prototyping.
Technical Context
The MSP430F5528IRGCT implements a 16-bit RISC CPU with constant generators and digitally controlled oscillator (DCO), supporting up to 25-MHz system clock via FLL-stabilized XT2 (up to 32 MHz crystal) or internal REFO/VLO sources. Its unified clock system enables dynamic low-power mode transitions with 3.5 µs wakeup from LPM3.
Power management integrates a programmable LDO core regulator, supply voltage supervisor (SVS), brownout reset (BOR), and multiple low-power modes (LPM0–LPM4.5). The USB subsystem includes integrated 3.3-V/1.8-V power rails, USB-PLL, and eight endpoints-fully compliant with USB 2.0 full-speed (12 Mbps) operation without external PHY components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal USB microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5529IPN | 80-pin LQFP; 63 GPIOs; 128 KB flash; 16-channel ADC; same USB/RTC/timer peripherals | Higher I/O count and memory for complex USB composite devices or multi-sensor fusion | Select when >47 GPIOs or >64 KB flash required; not pin-compatible due to package and pin count mismatch |
| MSP430F5526IRGCT | Same 64-pin VQFN package; 32 KB flash; 4 KB RAM; identical peripheral set except reduced memory | Suitable for cost-sensitive USB peripherals with simpler firmware (e.g., HID keyboard, basic sensor dongle) | Select for lower BOM cost where flash/RAM headroom is sufficient; pin-to-pin compatible with MSP430F5528IRGCT |
Compared with MSP430F5529IPN, MSP430F5528IRGCT trades I/O count and memory for compact VQFN packaging and lower system footprint; compared with MSP430F5526IRGCT, it provides double the flash and RAM for more sophisticated USB protocol stacks or larger sensor buffers-without changing PCB layout.

FAQ
What is the maximum operating frequency of the MSP430F5528IRGCT?
The MSP430F5528IRGCT supports a maximum system clock of 25 MHz, achieved via the FLL-controlled DCO using either an external high-frequency crystal (XT2, up to 32 MHz) or internal reference sources. This frequency enables real-time USB packet processing and deterministic timer-based sensor sampling without compromising ultra-low-power operation in active mode.
Does the MSP430F5528IRGCT require an external USB transceiver?
No, the MSP430F5528IRGCT does not require an external USB transceiver. It integrates a full-speed USB 2.0 PHY, USB-PLL, and dedicated 3.3-V/1.8-V power system, allowing direct connection of DP/DM lines to a USB connector. The internal 1.5-kΩ pullup resistor on DP (controlled by PUR pin) completes USB device enumeration per specification.
How many analog input channels does the ADC in the MSP430F5528IRGCT support?
The MSP430F5528IRGCT features a 12-bit ADC (ADC12_A) with 12 total input channels: 10 external analog inputs (P1.0–P1.7, P2.0–P2.1) and 2 internal sources (temperature sensor and VREF generator). Channel selection, sampling rate, and autoscan sequencing are fully configurable via dedicated ADC control registers.
What low-power modes are available on the MSP430F5528IRGCT, and what is the lowest current draw?
The MSP430F5528IRGCT offers five low-power modes (LPM0–LPM4.5). The lowest current draw is in LPM4.5 (shutdown mode) at 0.18 µA typical @ 3.0 V, with full RAM retention and supply supervisor active. LPM3 (RTC active) draws 1.9 µA @ 3.0 V, enabling timekeeping and fast 3.5 µs wakeup for event-driven operation.
Is the MSP430F5528IRGCT pin-compatible with other devices in the MSP430F55xx family?
The MSP430F5528IRGCT is pin-compatible with MSP430F5526IRGCT and MSP430F5524IRGCT in the same 64-pin VQFN (RGC) package. It is not pin-compatible with 80-pin variants like MSP430F5529IPN due to differing pin counts and package footprints. Peripheral register mapping remains consistent across the F552x series for software portability.
