Product details
Overview
MSP430F5528IRGC from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller with integrated USB 2.0 PHY, 12-bit ADC (10 external + 2 internal channels), four 16-bit timers (TA0/TA1/TA2/TB0), two USCI modules (UART/IrDA/SPI/I²C), RTC, hardware multiplier, and 3-channel DMA. It operates from 1.8 V to 3.6 V and targets USB-connected sensor nodes and portable data loggers requiring sub-2 µA standby current.
For engineers reviewing the MSP430F5528IRGC datasheet, MSP430F5528IRGC pinout, MSP430F5528IRGC application, or MSP430F5528IRGC equivalent, key selection criteria include its 64-pin VQFN package, 47 GPIOs, 64 KB flash / 8 KB + 2 KB RAM memory map, USB-capable peripheral set, and verified LPM3 current of 1.9 µA at 2.2 V - all confirmed for the exact MSP430F5528IRGC variant.
Technical Context
The MSP430F5528IRGC implements a 16-bit RISC CPUXV2 core with constant generators and unified clock system featuring FLL stabilization, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz). Its power architecture includes an integrated LDO with programmable core voltage, SVM/SVS supervision, and brownout reset.
Peripherals are mapped to 47 I/O pins across Ports P1–P6 in the 64-pin VQFN package, with dedicated USB DP/DM/PUR pins, ADC12_A input channels on P1–P6, and timer capture/compare functions distributed across TA0 (5 CC), TA1 (3 CC), TA2 (3 CC), and TB0 (7 CC) modules - all explicitly confirmed for MSP430F5528IRGC in Figure 4-2 and Device Information tables.

FAQ
What is the maximum system clock frequency supported by the MSP430F5528IRGC?
The MSP430F5528IRGC supports a maximum system clock frequency of 25 MHz, achieved via the FLL-controlled DCO using XT2 (up to 32 MHz crystal) or internal references. This frequency is validated in Section 8.19 (DCO Frequency) and enables USB 2.0 full-speed operation and real-time sensor processing. The MSP430F5528IRGC datasheet specifies timing parameters for all peripherals at this rate, including ADC conversion time and timer resolution.
Does the MSP430F5528IRGC include an integrated USB transceiver?
Yes, the MSP430F5528IRGC integrates a full-speed USB 2.0 transceiver (PHY), USB-LDO, and USB-PLL - confirmed in Section 3 Description and Figure 4-2. This eliminates the need for external USB physical layer components. The DP/DM pins connect directly to the USB connector, and PUR controls the internal 1.5-kΩ pullup resistor required for USB speed detection. No external transceiver IC is needed for MSP430F5528IRGC-based designs.
How many analog input channels does the 12-bit ADC on the MSP430F5528IRGC support?
The MSP430F5528IRGC features the ADC12_A module with 12 total input channels: 10 external analog inputs (mapped to P1.0–P1.7, P2.0–P2.1, and P6.0–P6.1) and 2 internal sources (temperature sensor and VREF generator), as specified in Figure 4-2 and Section 8.35. This configuration is distinct from the MSP430F5529IPN (16-channel ADC) and is validated for the MSP430F5528IRGC variant in the functional block diagram and device comparison tables.
What is the standby current consumption of the MSP430F5528IRGC in LPM3 mode?
The MSP430F5528IRGC consumes 1.9 µA at 2.2 V in LPM3 mode with RTC, watchdog, and supply supervisor active and full RAM retention - a value explicitly measured and published in Section 8.5 (Low-Power Mode Supply Currents) of the datasheet. This current is confirmed for the MSP430F5528IRGC variant and forms the basis for multi-year battery life calculations in sensor node applications.
Which development tools are officially supported for the MSP430F5528IRGC?
Texas Instruments officially supports the MSP430F5528IRGC with the MSP-TS430RGC64USB 64-pin target development board (designed for RGC-package devices), MSP430Ware™ software libraries, Code Composer Studio™ IDE, and MSP430F5529 LaunchPad™ (via socket adapter or firmware compatibility). These tools are listed in Section 1 and Section 3 of the datasheet and validated for debugging, flash programming, and USB enumeration testing of the MSP430F5528IRGC.
