Product details
Overview
MSP430F5359IZCAR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 512 KB flash, 66 KB RAM, integrated LDO, four 16-bit timers, 12-bit ADC (200 ksps, 16 channels), dual 12-bit DACs, RTC with alarm, and up to 74 GPIOs - designed for battery-powered sensor systems and digital thermostats requiring sub-2 µA standby current and 3 µs wake-up.
For engineers reviewing the MSP430F5359IZCAR datasheet, MSP430F5359IZCAR pinout, MSP430F5359IZCAR application, or MSP430F5359IZCAR equivalent, key selection criteria include LPM3 current (2.0 µA at 3.0 V), USB absence, LCD driver exclusion, nFBGA-113 package compatibility, and functional equivalence within the MSP430F535x series for cost-optimized embedded control.
Technical Context
The MSP430F5359IZCAR implements a unified clock system with FLL stabilization, VLO and REFO internal sources, XT1 (32 kHz crystal), and XT2 (up to 32 MHz), enabling precise timing across active and low-power modes. Its power management includes programmable LDO core regulation, supply voltage supervision, and brownout detection.
Peripheral integration centers on three USCI modules (USCI_A0–A2 supporting UART/IrDA/SPI; USCI_B0–B2 supporting I²C/SPI), 6-channel DMA, hardware multiplier, CRC16 engine, and memory integrity detection (MID). It lacks USB-PHY and LCD_B blocks present in higher-tier F565x/F665x variants.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5358IZCAR | 384 KB flash, 34 KB RAM, identical peripherals and package; lower memory capacity. | Suitable for simpler firmware with smaller code footprint and reduced data buffering needs. | Select when application fits within 384 KB flash and benefits from identical pinout and qualification. |
| MSP430F6459IPZ | LQFP-100 package (14 mm × 14 mm), adds integrated LCD driver (160 segments), retains same flash/RAM/peripherals except USB. | Preferred for designs requiring segment LCD display and larger PCB real estate; excludes nFBGA space constraints. | Choose when LCD interface is required and board layout accommodates larger package; not drop-in compatible with ZCA. |
Compared with MSP430F5359IZCAR, the F5358IZCAR offers identical low-power performance and pinout at lower memory cost, while the F6459IPZ trades nFBGA compactness for integrated LCD support - making the MSP430F5359IZCAR optimal for space-constrained, non-display, high-memory embedded control.

FAQ
Does MSP430F5359IZCAR support USB functionality?
No, MSP430F5359IZCAR does not include USB-PHY, USB-PLL, or USB power circuitry. It belongs to the MSP430F535x subfamily, which omits USB entirely - unlike the MSP430F565x or MSP430F665x families. For USB-enabled designs, consider MSP430F5659IZCAR instead, but note it requires PCB redesign due to different pinout and power architecture.
What is the maximum operating frequency of MSP430F5359IZCAR?
The MSP430F5359IZCAR supports a maximum system clock (MCLK) of 20 MHz, achieved via the FLL-controlled DCO or external XT2 crystal up to 32 MHz. At 20 MHz and 3.0 V, active-mode current is 295 µA/MHz (typical), enabling high-speed ADC sampling and real-time computation while maintaining ultra-low-power efficiency.
Is MSP430F5359IZCAR pin-compatible with other nFBGA-113 MSP430 devices?
Yes, MSP430F5359IZCAR shares the same nFBGA-113 (ZCA) mechanical footprint and I/O mapping with MSP430F5358IZCAR, MSP430F5658IZCAR, and MSP430F6459IZCAR. However, peripheral enablement differs - e.g., USB signals are no-connect on MSP430F5359IZCAR - so firmware and power design must align with its specific feature set.
What low-power modes are available on MSP430F5359IZCAR?
MSP430F5359IZCAR supports five low-power modes: LPM0–LPM4 plus LPM3.5 and LPM4.5. Key modes include LPM3 (2.0 µA, RTC active), LPM3.5 (1.1 µA, RTC + crystal only), and LPM4.5 (0.45 µA, full shutdown). Wake-up from LPM3 occurs in 3 µs (typical) via interrupts or RTC alarm - critical for responsive sensor wake-on-event behavior.
Does MSP430F5359IZCAR include an integrated LCD driver?
No, MSP430F5359IZCAR excludes the LCD_B module present in MSP430F645x and MSP430F665x devices. Its peripheral set focuses on general-purpose analog/digital I/O, timers, and serial interfaces - making it ideal for non-display applications like sensor nodes or industrial timers where LCD support would add unnecessary cost and power overhead.
