Product details
Overview
MSP430F5359IZQWT from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller with 512 KB flash, 66 KB RAM, four 16-bit timers, three USCI modules (UART/IrDA/SPI/I²C), 12-bit ADC (16 channels), dual 12-bit DACs, comparator, RTC, and integrated LDO - designed for battery-powered sensor systems and portable meters requiring sub-2 µA standby current.
For engineers reviewing the MSP430F5359IZQWT datasheet, MSP430F5359IZQWT pinout, MSP430F5359IZQWT application, or MSP430F5359IZQWT equivalent, this page delivers verified specifications, package mapping to MicroStar Junior™ BGA-113, functional block diagram alignment, real-world use scenarios, and two validated alternative parts for design continuity.
Technical Context
The MSP430F5359IZQWT implements the MSP430Xv2 CPU core with constant generators and 16-bit RISC architecture, operating up to 20 MHz via FLL-stabilized DCO or external crystals (XT1/XT2). Its unified clock system supports simultaneous ACLK, SMCLK, and MCLK domains with low-frequency VLO and trimmed REFO sources.
Power management includes an integrated 3.3-V LDO with programmable core voltage regulation, supply supervision (SVS/SVM), brownout reset, and five low-power modes (LPM0–LPM4.5); wakeup from LPM3 occurs in 3 µs typical using hardware-accelerated interrupt vector fetch.
Key Specifications

|---|---|
| Core Architecture | 16-bit RISC CPUXV2 with 16-bit registers and hardware multiplier supporting 32-bit operations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5359IPZ | LQFP-100 package (14 mm × 14 mm); same core, peripherals, and memory - no USB or LCD support | Better thermal dissipation and hand-solderability; requires larger PCB area and lacks BGA's high I/O density | Select when board-level test access, rework feasibility, or thermal margin outweigh compactness requirements |
| MSP430F5358IZQWT | 384 KB flash, 34 KB RAM - reduced code/data capacity but identical package, pinout, and peripheral set | Suitable for cost-sensitive designs with smaller firmware footprint and fewer runtime variables | Choose when application fits within 384 KB flash and avoids features requiring >34 KB RAM (e.g., deep sensor buffers) |
Compared with MSP430F5359IZQWT, the IPZ variant trades BGA miniaturization for manufacturability and thermal headroom, while the F5358IZQWT offers identical form-factor compatibility at lower memory cost - both retain full LDO, RTC, ADC, and USCI functionality without USB or LCD.

FAQ
What is the maximum system clock frequency supported by the MSP430F5359IZQWT?
The MSP430F5359IZQWT supports up to 20 MHz system clock via its digitally controlled oscillator (DCO) with FLL stabilization, or through external high-frequency crystals up to 32 MHz on XT2. This enables deterministic real-time response for metrology and control loops while maintaining ultra-low power in active mode (295 µA/MHz at 8 MHz, 3.0 V).
Does the MSP430F5359IZQWT include a USB interface?
No, the MSP430F5359IZQWT does not include USB functionality. Unlike the MSP430F565x or MSP430F665x families, the F535x series omits the USB PHY, endpoints, and associated power circuitry - confirmed in the Device Comparison table and functional block diagram (Figure 4-3). USB capability is exclusive to F565x/F665x variants.
What package type and pin count does the MSP430F5359IZQWT use?
The MSP430F5359IZQWT uses the MicroStar Junior™ BGA-113 package (7 mm × 7 mm, 0.5-mm pitch) with 74 functional I/O pins distributed across ports P1–P9, PJ, and PU. Pin configuration matches other ZQW variants in the F535x family, enabling layout reuse across memory variants like MSP430F5358IZQWT.
How much RAM and flash memory does the MSP430F5359IZQWT provide?
The MSP430F5359IZQWT integrates 512 KB of on-chip flash memory and 66 KB of SRAM. This memory allocation supports complex sensor fusion algorithms, secure boot code, and large calibration tables - exceeding the 384 KB flash / 34 KB RAM of the pin-compatible MSP430F5358IZQWT.
What low-power modes are available on the MSP430F5359IZQWT, and what are their typical currents?
The MSP430F5359IZQWT offers five low-power modes: LPM0–LPM4.5. Key currents include 2.0 µA in LPM3 (watchdog + crystal RTC active), 1.1 µA in LPM3.5 (RTC-only with crystal), and 0.45 µA in LPM4.5 (full shutdown). These values are measured at 3.0 V and enable decade-long operation on primary lithium cells.
