Product details
Overview
MSP430F5528IZXHR 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, hardware multiplier, and 3-channel 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 hubs and portable data loggers with USB connectivity.
For engineers reviewing the MSP430F5528IZXHR datasheet, MSP430F5528IZXHR pinout, MSP430F5528IZXHR application, or MSP430F5528IZXHR equivalent, key selection criteria include its nFBGA-80 (5 mm × 5 mm) package, 47 I/O pins, USB-capable architecture, LPM4.5 shutdown current of 0.18 µA, and compatibility with TI's MSP430Ware™ and LaunchPad™ ecosystem for rapid prototyping.
Technical Context
The MSP430F5528IZXHR implements a 16-bit RISC CPU with constant generators and extended memory addressing, paired with a unified clock system featuring FLL stabilization, VLO, REFO, XT1 (32-kHz crystal), and XT2 (up to 32-MHz crystal). Its power management includes an integrated LDO with programmable core voltage and supply supervision with brownout detection.
USB functionality is fully integrated via dedicated USB-PHY, USB-PLL, and dual-voltage (3.3-V/1.8-V) USB power system, supporting eight endpoints and full-speed (12 Mbps) operation without external components. The 12-bit ADC supports autoscan across 12 channels (10 external, 2 internal), with sample rates up to 200 ksps and internal reference.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power USB MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5529IPN | 80-pin LQFP package; 63 I/O pins; identical USB/ADC/timer peripherals but larger footprint and higher pin count | Better suited for development and applications requiring maximum I/O expansion or debug access | Select when board layout allows LQFP-80 and >47 GPIOs are needed; not pin-compatible with MSP430F5528IZXHR |
| MSP430F5528IRGC | VQFN-64 (9 mm × 9 mm); 47 I/O pins; same core specs and USB/ADC features but different package and thermal profile | Preferred for reflow-soldered designs needing better thermal dissipation than nFBGA | Choose for automated assembly with optical alignment; requires PCB redesign due to different pad layout and ball/pad count |
Compared with MSP430F5529IPN and MSP430F5528IRGC, the MSP430F5528IZXHR provides identical functional capability in the smallest footprint (5 mm × 5 mm nFBGA), optimizing board area for miniaturized USB peripherals where I/O count is constrained to 47.

FAQ
What is the maximum operating frequency of the MSP430F5528IZXHR?
The MSP430F5528IZXHR supports a maximum system clock frequency of 25 MHz, achieved via its digitally controlled oscillator (DCO) with FLL stabilization. This frequency applies to MCLK and is confirmed in the device's electrical specifications under recommended operating conditions; actual sustained speed depends on supply voltage and temperature, with 8 MHz typical for ultra-low-power active mode operation.
Does the MSP430F5528IZXHR include an integrated USB transceiver?
Yes, the MSP430F5528IZXHR integrates a full-speed USB 2.0 PHY, USB-PLL, and dual-voltage (3.3-V/1.8-V) USB power system. It requires no external USB transceiver or clock source - only standard USB connector wiring to DP and DM pins and proper 90-Ω differential impedance routing.
How many analog input channels does the ADC in the MSP430F5528IZXHR support?
The MSP430F5528IZXHR features a 12-bit ADC (ADC12_A) with 12 total input channels: 10 external analog inputs (A0–A9) and 2 internal sources (temperature sensor and VREF/2). This matches the functional block diagram for RGC/ZXH/ZQE-package variants and is distinct from the 16-channel version in PN-package devices like MSP430F5529IPN.
What low-power modes are available on the MSP430F5528IZXHR, and what is the lowest current draw?
The MSP430F5528IZXHR supports five low-power modes (LPM0–LPM4 plus LPM4.5). The lowest current draw is in LPM4.5 (shutdown mode), consuming 0.18 µA at 3.0 V with full RAM retention and supply supervisor active - verified in Section 8.5 of the SLAS590P datasheet.
Is the MSP430F5528IZXHR pin-compatible with other members of the MSP430F552x family?
No, the MSP430F5528IZXHR (nFBGA-80) is not pin-compatible with MSP430F5529IPN (LQFP-80) or MSP430F5528IRGC (VQFN-64). While functionally similar, each package has unique ball/pad mapping, I/O assignment, and power pin placement - requiring separate PCB layouts per variant.
