Product details
Overview
MSP430F5528IRGCR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with integrated USB 2.0 PHY, 12-bit ADC (12 external channels), four 16-bit timers, two USCI modules (UART/IrDA/SPI/I²C), RTC, hardware multiplier, and DMA. 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 MSP430F5528IRGCR datasheet, MSP430F5528IRGCR pinout, MSP430F5528IRGCR application, or MSP430F5528IRGCR equivalent, key selection criteria include its 64-pin VQFN package, 47 GPIOs, USB-capable operation without external transceiver, 12-bit ADC with autoscan, and LPM4.5 shutdown current of 0.18 µA - critical for energy-constrained embedded designs.
Technical Context
The MSP430F5528IRGCR implements a 16-bit RISC CPU with constant generators and extended memory addressing, paired with a unified clock system featuring FLL stabilization, VLO/REFO internal sources, and support for 32-kHz XT1 and up to 32-MHz XT2 crystals. Its power architecture integrates a programmable LDO core regulator and supply supervision with brownout detection.
Peripherals are tightly synchronized via three-channel DMA and port-mapped I/O control. The USB subsystem includes integrated 3.3-V/1.8-V power regulation, USB-PLL, and eight endpoints - all operating natively without external components. The 12-bit ADC supports up to 200 ksps with internal reference and sample-and-hold.

FAQ
What is the maximum system clock frequency supported by the MSP430F5528IRGCR?
The MSP430F5528IRGCR supports a maximum system clock frequency of 25 MHz. This is achieved using the integrated digitally controlled oscillator (DCO) with FLL stabilization or by driving the MCLK from the high-frequency XT2 oscillator (up to 32 MHz crystal). At 25 MHz, the device maintains full peripheral functionality including USB 2.0 full-speed operation, 12-bit ADC sampling at 200 ksps, and real-time timer operations - all verified in TI's SLAS590P specification table.
Does the MSP430F5528IRGCR include an integrated USB transceiver?
Yes, the MSP430F5528IRGCR includes a fully integrated USB 2.0 full-speed physical layer (PHY), USB-PLL, and dedicated 3.3-V/1.8-V USB power system. No external USB transceiver, clock source, or voltage regulators are required. The DP and DM pins connect directly to the USB connector, and the PUR pin controls the internal 1.5-kΩ pullup resistor for USB speed detection - confirmed in Section 4.2 and Figure 4-2 of the SLAS590P datasheet.
How many analog input channels does the 12-bit ADC in the MSP430F5528IRGCR support?
The MSP430F5528IRGCR features a 12-bit ADC (ADC12_A) with 12 external analog input channels and 2 internal channels (temperature sensor and VMID). This is explicitly stated in the functional block diagram (Figure 4-2) and Section 1, Features. It differs from the MSP430F5529 variant, which offers 16 total channels (14 external). Channel selection is managed via the ADC12MCTLx registers and supports autoscan mode for unattended multi-channel conversion sequences.
What is the wakeup time from LPM3 standby mode for the MSP430F5528IRGCR?
The MSP430F5528IRGCR wakes up from LPM3 (standby mode with RTC active) in 3.5 µs (typical), as specified in Section 1, Features and Table 8.26 of SLAS590P. This fast wakeup is enabled by the integrated DCO and FLL circuitry, allowing immediate resumption of active-mode processing after RTC alarm or external interrupt - critical for duty-cycled sensor applications where latency impacts measurement accuracy or responsiveness.
Is the MSP430F5528IRGCR pin-compatible with other devices in the MSP430F55xx family?
No, the MSP430F5528IRGCR is not pin-compatible with other MSP430F55xx variants due to differing package types and I/O counts. It uses a 64-pin VQFN (RGC) package with 47 GPIOs, whereas MSP430F5529IPN uses an 80-pin LQFP with 63 GPIOs, and MSP430F5528IZXH uses an 80-pin nFBGA. Pin assignments, power domains (e.g., AVCC/DVCC placement), and USB signal routing (DP/DM location) vary across packages - confirmed in Figures 7-1 through 7-6 of SLAS590P.
