Product details
Overview
MSP430F5359IZQWR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 512 KB flash, 66 KB RAM, four 16-bit timers, a 12-bit 200-ksps ADC with 16 channels (12 external, 4 internal), two 12-bit DACs, and up to 74 GPIO pins in a 113-pin MicroStar Junior™ BGA package. It targets battery-powered sensor systems and digital timers requiring extended runtime and integrated analog peripherals.
For engineers reviewing the MSP430F5359IZQWR datasheet, MSP430F5359IZQWR pinout, MSP430F5359IZQWR application, or MSP430F5359IZQWR equivalent, key selection criteria include LPM3 standby current (2.0 µA at 3.0 V), 3 µs wake-up time, integrated LDO, RTC with battery backup, and absence of USB/LCD peripherals compared to higher-tier F565x/F665x variants.
Technical Context
The MSP430F5359IZQWR implements a 16-bit RISC CPUXV2 core with constant generators and hardware multiplier supporting 32-bit operations. Its unified clock system includes FLL stabilization, VLO and REFO internal sources, XT1 (32-kHz crystal), and XT2 (up to 32-MHz crystal) - all managed via programmable LDO-regulated core voltage.
Peripherals are organized around six-channel DMA, three USCI modules (USCI_A0–A2 for UART/IrDA/SPI; USCI_B0–B2 for I²C/SPI), RTC_B with alarm and battery-switchover, and Comp_B with selectable reference inputs - all operating under five low-power modes optimized for portable measurement applications.
Key Specifications

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, memory, and peripheral set as MSP430F5359IZQWR. | Better suited for prototyping and manual assembly due to larger pitch and visible leads. | Select when board-level test access, reworkability, or legacy PCB compatibility is required over compact BGA footprint. |
| MSP430F5358IZQWR | 384 KB flash, 34 KB RAM - reduced memory capacity; otherwise identical architecture, package, and peripherals. | Appropriate for cost-sensitive designs with simpler firmware and smaller data buffers. | Choose when application firmware fits within 384 KB flash and 34 KB RAM - lowers unit cost without changing layout or software porting effort. |
Compared with MSP430F5359IZQWR, the IPZ variant trades miniaturization for assembly flexibility, while the F5358IZQWR reduces memory to lower cost - both retain identical low-power behavior, peripheral configuration, and pin-compatible I/O mapping.

FAQ
What is the maximum system clock frequency supported by the MSP430F5359IZQWR?
The MSP430F5359IZQWR supports a maximum system clock frequency of 20 MHz. This is achieved using the FLL-controlled DCO or external high-frequency crystals up to 32 MHz on XT2 - though the CPU and most peripherals are rated for 20-MHz operation per the device specification. The 20-MHz limit ensures timing compliance across all integrated modules including ADC, timers, and USCI interfaces.
Does the MSP430F5359IZQWR include USB or LCD peripheral support?
No, the MSP430F5359IZQWR does not include USB or LCD peripheral support. Unlike the MSP430F565x and MSP430F665x families, the F535x series omits the USB-PHY, USB-PLL, and LCD_B modules. This differentiation is confirmed in the Device Comparison table (SLAS700E Table 6-1), where MSP430F5359 shows "No" for both USB and LCD columns - making it a cost-optimized variant for applications needing only core mixed-signal capability.
What are the key power-management features of the MSP430F5359IZQWR?
The MSP430F5359IZQWR integrates a fully programmable LDO regulator, supply voltage supervisor (SVS), brownout reset (BOR), and five low-power modes (LPM0–LPM4.5). Its LPM3 draws just 2.0 µA at 3.0 V with RTC active and full RAM retention, while LPM4.5 consumes only 0.45 µA in shutdown - enabling multi-year operation on small batteries. Wake-up from LPM3 occurs in 3 µs, preserving real-time responsiveness.
How many universal serial communication interfaces (USCIs) does the MSP430F5359IZQWR have, and what protocols do they support?
The MSP430F5359IZQWR has three USCI modules: USCI_A0, USCI_A1, and USCI_A2 each support enhanced UART, IrDA, and synchronous SPI; USCI_B0, USCI_B1, and USCI_B2 each support I²C and synchronous SPI. This provides six independent serial channels - three for asynchronous (UART/IrDA) and three for synchronous (I²C/SPI) communication - enabling concurrent interfacing with multiple sensors, transceivers, or host processors without software bit-banging.
Is the MSP430F5359IZQWR pin-compatible with other devices in the MSP430F5xx family?
Yes, the MSP430F5359IZQWR is pin-compatible with other 113-pin ZQW-packaged members of the MSP430F5xx family, including MSP430F5358IZQWR, MSP430F5659IZQWR, and MSP430F6459IZQWR. All share identical MicroStar Junior™ BGA mechanical dimensions, pad layout, and I/O mapping per TI's package documentation - allowing shared PCB footprints across variants differentiated by flash/RAM size, USB presence, or LCD support.
