Product details
Overview
MSP430F5335IPZ from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 256 KB flash, 18 KB RAM, integrated 3.3-V LDO, 12-bit ADC (200 ksps, 16 channels), dual USCI modules (UART/IrDA/SPI/I²C), four 16-bit timers, RTC with battery backup, and 74 GPIO pins in a 100-pin LQFP package - deployed in battery-powered sensor systems and portable meters.
For engineers reviewing the MSP430F5335IPZ datasheet, MSP430F5335IPZ pinout, MSP430F5335IPZ application, or MSP430F5335IPZ equivalent, this page delivers verified functional architecture, low-power mode timing (3 µs wake-up), ADC linearity specs, DAC absence confirmation, and validated alternative MCUs for migration or sourcing continuity.
Technical Context
The MSP430F5335IPZ implements a unified clock system with FLL stabilization, VLO/REFO internal sources, XT1 (32 kHz) and XT2 (up to 32 MHz) crystal support, and programmable core voltage via integrated LDO. Its five low-power modes (LPM0–LPM4.5) are managed by the Power Management Module with SVS/SVM supervision and brownout reset.
Peripherals include ADC12_A with autoscan and internal reference (1.5/2.0/2.5 V), Comparator_B, 6-channel DMA, hardware multiplier (MPY32), and two USCIs - USCI_A0/A1 supporting UART/IrDA/SPI, and USCI_B0/B1 supporting I²C/SPI - all operating across supply range 1.8–3.6 V with full RAM retention in LPM3.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5336IPZ | 128 KB flash, same 18 KB RAM, identical peripherals except no DAC - otherwise pin- and code-compatible. | Suitable where firmware size <128 KB suffices and DAC functionality is unused - lower cost with identical low-power behavior and I/O count. | Select when flash budget permits reduction and DAC is unnecessary; retains full LPM3/LPM4.5 current and wake-up timing. |
| MSP430F5338IPZ | 256 KB flash, 18 KB RAM, adds dual 12-bit DAC12_A - otherwise identical clocking, timers, ADC, and package. | Required when analog waveform generation (e.g., sensor excitation, calibration signals) is needed alongside existing MSP430F5335IPZ functionality. | Choose only if DAC outputs are essential; shares same pinout and software framework but increases BOM cost and power in active DAC use. |
Compared with MSP430F5335IPZ, MSP430F5336IPZ offers identical low-power operation and peripheral set at reduced flash capacity, while MSP430F5338IPZ extends functionality with dual DACs - both maintain LQFP-100 compatibility and require no PCB changes for drop-in replacement where DAC is unused or added.

FAQ
What is the maximum system clock frequency supported by the MSP430F5335IPZ?
The MSP430F5335IPZ supports a maximum system clock frequency of 20 MHz, achieved via its digitally controlled oscillator (DCO) or external high-frequency crystal (XT2) up to 32 MHz. The device's FLL control loop stabilizes the DCO, and timing specifications in the datasheet confirm reliable operation at 20 MHz across the full 1.8–3.6 V supply range. This frequency enables high-throughput ADC sampling and real-time control loops while maintaining ultra-low power consumption in active mode.
Does the MSP430F5335IPZ include a DAC peripheral?
No, the MSP430F5335IPZ does not include a DAC peripheral. Device comparison data explicitly lists DAC12_A channels as "–" for MSP430F5335 and MSP430F5333, distinguishing them from MSP430F5338 and MSP430F5336 which include dual 12-bit DACs. All other analog peripherals - including the 12-bit ADC12_A, Comparator_B, and internal voltage references - remain fully present and functional in the MSP430F5335IPZ.
What package type and pin count does the MSP430F5335IPZ use?
The MSP430F5335IPZ uses a 100-pin LQFP (PZ) package measuring 14 mm × 14 mm with an exposed thermal pad. It provides 74 general-purpose I/O pins, plus dedicated power, ground, crystal, reset, and debug interface pins. This package is mechanically and electrically compatible with other members of the MSP430F533x family in the PZ variant, enabling design reuse across flash variants.
How does the MSP430F5335IPZ achieve ultra-low power consumption in standby mode?
The MSP430F5335IPZ achieves 1.8 µA standby current (LPM3) at 2.2 V by disabling the CPU and main system clocks while keeping the watchdog timer, 32-kHz crystal oscillator (XT1), and supply supervisor active - retaining full RAM contents and enabling 3 µs wake-up. Its integrated LDO operates in low-power mode, and the Power Management Module (PMM) maintains regulated core voltage with minimal quiescent current, making it ideal for infrequently polled sensor nodes.
Which communication interfaces are supported by the MSP430F5335IPZ?
The MSP430F5335IPZ supports two universal serial communication interfaces (USCIs): USCI_A0 and USCI_A1 each provide UART (with automatic baud-rate detection), IrDA, and SPI; USCI_B0 and USCI_B1 each support I²C and SPI. These interfaces operate independently, allowing concurrent UART-based debugging, I²C sensor polling, and SPI display updates - all while maintaining full low-power mode compatibility and pin multiplexing flexibility.
