Product details
Overview
MSP430F5528IZQER 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 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) - optimized for battery-powered sensor nodes and USB-connected data loggers.
For engineers reviewing the MSP430F5528IZQER datasheet, MSP430F5528IZQER pinout, MSP430F5528IZQER application, or MSP430F5528IZQER equivalent, key selection criteria include its MicroStar Junior™ BGA-80 package, 47 I/O pins, USB-capable architecture, LPM3 standby current of 1.9 µA (3.0 V), and ADC channel count versus competing F5529/F5527 variants.
Technical Context
The MSP430F5528IZQER implements a 16-bit RISC CPU with extended memory addressing, digitally controlled oscillator (DCO), and unified clock system featuring FLL stabilization, REFO/XT1/XT2/VLO sources. Its power management includes an integrated LDO with programmable core voltage and supply supervision with brownout detection.
Peripherals are mapped via port mapping control (P4), supporting flexible I/O assignment across P1–P6. The device uses a segmented memory architecture with 64 KB flash and 8 KB + 2 KB RAM, and supports serial on-board programming without external voltage.

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, 63 I/O, 128 KB flash, 16-channel ADC (14 ext) | Higher I/O count and flash capacity for complex USB+sensor+display systems | Select when board layout accommodates LQFP and design requires >47 GPIO or >64 KB code space |
| MSP430F5528IRGC | 64-pin VQFN, 47 I/O, same peripherals and memory as ZQE variant | Same functionality in thermally enhanced exposed-pad package - better for convection-cooled or high-reliability environments | Select when thermal performance or reflow compatibility outweighs BGA assembly requirements |
Compared with MSP430F5529IPN, the MSP430F5528IZQER trades I/O count and flash size for compact BGA packaging and identical USB/ADC/timer capability; compared with MSP430F5528IRGC, it offers identical functionality in a smaller footprint but requires BGA assembly infrastructure.

FAQ
What is the package type and pin count of the MSP430F5528IZQER?
The MSP430F5528IZQER uses a MicroStar Junior™ BGA-80 package with 80 balls arranged in a 5 mm × 5 mm array and 0.5-mm pitch. It provides 47 general-purpose I/O pins, as confirmed in TI's SLAS590P datasheet Section 3 and Figure 4-2. This BGA variant shares identical functionality with the VQFN and nFBGA versions of the MSP430F5528, differing only in mechanical form factor and ball assignment.
Does the MSP430F5528IZQER include a USB physical layer?
Yes, the MSP430F5528IZQER integrates a full-speed USB 2.0 PHY, USB-PLL, and dual-voltage (3.3-V/1.8-V) USB power system. This eliminates the need for external transceivers or level shifters. The DP/DM pins connect directly to a USB connector, and the PUR pin controls the internal 1.5-kΩ pullup resistor required for USB enumeration - all documented in Section 4.2 and Table 8-44/45 of the MSP430F5528IZQER datasheet.
How many analog input channels does the ADC support on the MSP430F5528IZQER?
The MSP430F5528IZQER features a 12-bit ADC (ADC12_A) with 12 external input channels and 2 internal channels (temperature sensor and VREF). This is explicitly stated in Section 4.2 (Functional Block Diagram) and Section 8.35–8.39 of the datasheet. It differs from the MSP430F5529's 16-channel ADC, confirming the 12-channel count applies specifically to the F5528 variant in all packages including ZQE.
What is the lowest power consumption mode available on the MSP430F5528IZQER?
The lowest power mode is LPM4.5, drawing 0.18 µA at 3.0 V with full RAM retention and supply supervisor active. This mode disables all clocks and the LDO regulator while preserving SRAM contents - enabling ultra-long storage or deep sleep between infrequent wake events. Wake-up time from LPM4.5 is not specified, but LPM4 wake-up is 3.5 µs (typical), per Section 8.26 of the MSP430F5528IZQER datasheet.
Is the MSP430F5528IZQER pin-compatible with other MSP430F5528 package variants?
No - the MSP430F5528IZQER (MicroStar Junior BGA-80) is not pin-compatible with the MSP430F5528IRGC (VQFN-64) or MSP430F5528IZXH (nFBGA-80). Ball/pin assignments differ significantly across packages, as shown in Figures 7-10 (ZQE), 7-8 (RGC), and 7-9 (ZXH) of SLAS590P. Signal routing, power pin placement, and debug interface layout require unique PCB designs for each package.
