Product details
Overview
MSP430F5358IPZR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 384 KB flash, 34 KB RAM, integrated LDO, four 16-bit timers, 12-bit ADC (200 ksps, 16 channels), dual 12-bit DACs, USB 2.0 interface, and up to 74 GPIO pins in a 100-pin LQFP package. It targets battery-powered sensor systems and portable metering applications requiring long runtime and mixed-signal integration.
For engineers reviewing the MSP430F5358IPZR datasheet, MSP430F5358IPZR pinout, MSP430F5358IPZR application, or MSP430F5358IPZR equivalent, key selection criteria include its LDO-integrated power architecture, absence of USB and LCD peripherals versus higher-tier variants, verified 3 µs wake-up from LPM3, and compatibility with TI's MSP430F5xx toolchain and development ecosystem.
Technical Context
The MSP430F5358IPZR implements the CPUXV2 core with constant generators and 16-bit registers for optimized code density. Its unified clock system integrates FLL stabilization, VLO and REFO internal sources, XT1 (32 kHz crystal), and XT2 (up to 32 MHz) support - all managed via programmable clock gating and low-power mode transitions.
Power management includes a fully integrated LDO with programmable core voltage, supply supervision, brownout detection, and five low-power modes (LPM0–LPM4.5). The peripheral set is configured for standalone sensing and control: three USCIs (two UART/IrDA/SPI + one I²C/SPI), RTC_B with alarm and battery backup, 6-channel DMA, and hardware multiplier supporting 32-bit operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | CPUXV2 16-bit RISC with constant generators; enables compact firmware and deterministic interrupt latency. |
| Flash / RAM | 384 KB flash + 34 KB RAM; sufficient for complex sensor fusion algorithms and local data buffering without external memory. |
| ADC Performance | 12-bit ADC, 200 ksps, 16 channels (12 external + 4 internal); supports simultaneous sampling of multiple analog sensors. |
| Low-Power Modes | LPM3 draws 2.0 µA at 3.0 V; LPM4.5 draws 0.45 µA; enables multi-year operation on coin-cell batteries. |
| Wake-up Time | 3 µs from LPM3 to active mode; critical for responsive event-driven sensing in duty-cycled systems. |
| USB Support | No integrated USB PHY or endpoints; eliminates USB power overhead and simplifies layout for non-USB applications. |
| LCD Driver | No integrated LCD_B module; reduces die area and current draw where display is not required. |
Pinout & Package
LQFP-100 (14 mm × 14 mm) package with exposed thermal pad; RoHS-compliant, leaded finish; compatible with standard reflow profiles and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |

| P1.x–P9.x | General-purpose I/O ports | 74 total configurable GPIOs with interrupt capability, pull-up/down control, and Schmitt-trigger inputs for noisy environments. |
| XT1IN/XT1OUT | Low-frequency crystal oscillator terminals | Supports 32.768 kHz watch crystal for precise RTC timing and low-power sleep clock source. |
| XT2IN/XT2OUT | High-frequency crystal oscillator terminals | Accepts up to 32 MHz crystal or external clock for high-speed active-mode operation. |
| DVCC/DVSS | Digital supply and ground | Core logic powered by integrated LDO output; decoupling required per TI layout guidelines. |
| AVCC/AVSS | Analog supply and ground | Independent analog domain for ADC/DAC/REF; must be filtered and isolated from digital noise. |
Key Features

| Ultra-low-power RTC_B | Real-time clock with alarm and battery backup capability; retains time during main power loss using VBAT pin. |
| Hardware multiplier | 32-bit multiply-accumulate support; accelerates math-intensive tasks like FFTs or PID control without CPU overhead. |
| 6-channel DMA controller | Offloads data movement from CPU for ADC-to-RAM, UART-to-buffer, or timer-triggered transfers; preserves low-power mode residency. |

FAQ
What is the maximum system clock frequency supported by the MSP430F5358IPZR?
The MSP430F5358IPZR supports a maximum system clock frequency of 20 MHz. This is achieved using the FLL-controlled DCO or by directly routing the XT2 oscillator (up to 32 MHz) to MCLK. At 20 MHz, active-mode current is specified at 295 µA/MHz (typical) under 3.0 V conditions. The MSP430F5358IPZR does not support full 32 MHz operation across all voltage ranges per TI's recommended operating conditions.
Does the MSP430F5358IPZR include a USB interface?
No, the MSP430F5358IPZR does not include a USB interface. Unlike the MSP430F565x or MSP430F665x series, the MSP430F535x family omits the integrated USB-PHY, USB-PLL, and endpoint buffers. This is confirmed in the Device Comparison table (SLAS700E Table 6-1), where "USB" is marked "No" for MSP430F5358IPZR. Communication is supported via UART, SPI, and I²C through its three USCI modules.
What are the key differences between MSP430F5358IPZR and MSP430F5359IPZR?
The MSP430F5358IPZR and MSP430F5359IPZR share identical peripherals, package, and low-power characteristics, but differ in memory: MSP430F5358IPZR has 384 KB flash and 34 KB RAM, while MSP430F5359IPZR provides 512 KB flash and 66 KB RAM. Both lack USB and LCD drivers. The larger memory in MSP430F5359IPZR supports more complex firmware, extended data buffers, or dual-bank OTA updates - verified in TI's SLAS700E Device Comparison table.
Which development tools are officially supported for the MSP430F5358IPZR?
Texas Instruments officially supports the MSP430F5358IPZR with the MSP430FR2355 LaunchPad Development Kit (MSP-EXP430FR2355), IAR Embedded Workbench for MSP430, TI's Code Generation Tools (CGT), and MSP430Ware peripheral driver library. Debugging uses Spy-Bi-Wire via the RST/NMI/SBWTDIO pin. No dedicated target board exists for the F535x series, but generic MSP430F5xx-compatible debuggers and IDEs apply per TI's MSP430F5xx Family User's Guide.
What is the function of the PU.0 and PU.1 pins on the MSP430F5358IPZR?
The PU.0 and PU.1 pins on the MSP430F5358IPZR are dedicated to the integrated LDO regulator: PU.0 is the LDO output (LDOO) and PU.1 is the LDO input (LDOI). They enable internal regulation of DVCC from AVCC or an external supply, as documented in Section 8.52 and Figure 4-3 of SLAS700E. These pins must be externally decoupled with 1 µF ceramic capacitors and are not general-purpose I/Os.
