Product details
Overview
MSP430F5358IZCAT from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 384 KB flash, 34 KB RAM, four 16-bit timers, a 12-bit 200-ksps ADC with 16 channels (12 external, 4 internal), two 12-bit DACs, and integrated LDO for regulated core voltage-designed for battery-powered sensor systems and digital thermostats.
For engineers reviewing the MSP430F5358IZCAT datasheet, MSP430F5358IZCAT pinout, MSP430F5358IZCAT application, or MSP430F5358IZCAT equivalent, key selection criteria include standby current (2.0 µA at 3.0 V), wake-up time (3 µs), USB absence, LCD driver exclusion, and nFBGA-113 package compatibility with space-constrained embedded designs.
Technical Context
The MSP430F5358IZCAT implements a 16-bit RISC CPU with constant generators and a digitally controlled oscillator (DCO), enabling rapid transitions between five low-power modes-including LPM3 (2.0 µA) and LPM4.5 (0.45 µA). Its unified clock system integrates FLL, REFO, VLO, XT1 (32-kHz crystal), and XT2 (up to 32-MHz crystal) sources.
Peripheral integration includes three USCI modules (USCI_A0–A2 supporting UART/IrDA/SPI; USCI_B0–B2 supporting I²C/SPI), 6-channel DMA, RTC_B with alarm and battery backup, hardware multiplier for 32-bit operations, and memory integrity detection (MID). It lacks USB PHY and LCD_B blocks present in higher-tier F665x/F565x variants.

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 |
|---|---|---|---|
| MSP430F5359IZCAT | 512 KB flash, 66 KB RAM, identical peripherals and package; no USB/LCD | Higher firmware capacity for complex sensor fusion algorithms or bootloader + application partitioning | Select when firmware size exceeds 384 KB or additional RAM is needed for large buffers or RTOS stacks |
| MSP430F6458IPZ | LQFP-100 package (14 mm × 14 mm), same flash/RAM/peripherals but adds integrated LCD driver (160 seg) | Enables direct connection to segment-based displays without external driver IC | Choose for cost-sensitive designs requiring LCD interface and easier prototyping-accept larger footprint and no nFBGA option |
Compared with MSP430F5358IZCAT, the F5359 offers more memory headroom while maintaining identical power profile and pin compatibility in ZCA; the F6458 trades nFBGA miniaturization for LCD integration and larger package-making it suitable only where display driving is mandatory and board area is less constrained.

FAQ
What is the maximum system clock frequency supported by the MSP430F5358IZCAT?
The MSP430F5358IZCAT supports up to 20 MHz system clock frequency using the integrated FLL with XT2 crystal (up to 32 MHz) or internal DCO. This enables high-speed ADC sampling (200 ksps), real-time signal processing, and responsive peripheral handling while maintaining ultra-low active-mode current (295 µA/MHz at 8 MHz, 3.0 V).
Does the MSP430F5358IZCAT include USB functionality?
No, the MSP430F5358IZCAT does not include USB functionality. Unlike the MSP430F565x or MSP430F665x families, the F535x series omits the USB PHY, USB-PLL, and associated power circuitry. Communication relies on USCI modules supporting UART, IrDA, SPI, and I²C-making it ideal for RF-connected or wired serial sensor nodes where USB host interface is unnecessary.
What package type and dimensions does the MSP430F5358IZCAT use?
The MSP430F5358IZCAT uses an nFBGA-113 package measuring 7 mm × 7 mm with 0.5-mm ball pitch. This compact, thermally efficient package supports high-density PCB layouts in space-constrained applications like handheld meters and wearable sensors, and is compatible with standard reflow soldering processes.
How much RAM and flash memory does the MSP430F5358IZCAT provide?
The MSP430F5358IZCAT provides 384 KB of flash memory for program storage and 34 KB of RAM-including 2 KB of backup RAM retained during LPM3.5/LPM4.5 modes. This configuration balances firmware capacity for complex sensor algorithms with low-power data buffering needs in battery-operated devices.
Is the MSP430F5358IZCAT pin-compatible with other members of the MSP430F535x family?
Yes, the MSP430F5358IZCAT is pin-compatible with the MSP430F5359IZCAT in the same nFBGA-113 (ZCA) package. Both share identical pin functions, electrical characteristics, and peripheral mappings-allowing seamless migration to the higher-memory variant without PCB redesign when firmware growth demands it.
