Product details
Overview
MSP430F5239IZQE from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 128 KB flash, 8 KB RAM, four 16-bit timers (TA0/TA1/TA2/TB0), two USCI modules (UART/IrDA/SPI/I²C), RTC, hardware multiplier, DMA, and comparator-no ADC. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and data loggers requiring sub-2 µA standby current.
For engineers reviewing the MSP430F5239IZQE datasheet, MSP430F5239IZQE pinout, MSP430F5239IZQE application, or MSP430F5239IZQE equivalent, key selection factors include its ZQE 80-pin MicroStar Junior BGA package, absence of integrated ADC (vs. F524x series), LPM3 current of 1.9 µA at 3.0 V, 3.5 µs wake-up time, and dual-USCI support for mixed wired communication protocols.
Technical Context
The MSP430F5239IZQE implements a unified clock system with FLL-based frequency stabilization, programmable LDO core regulation, and multiple low-frequency sources (VLO, REFO, XT1, XT2). Its CPUXV2 core supports 25-MHz operation and executes instructions in single-cycle mode for deterministic timing.
Peripherals are mapped via port multiplexing across eight I/O ports (P1–P7, PJ) with Schmitt-trigger inputs, configurable drive strength, and interrupt-capable pins. The device lacks ADC10_A but retains full COMP_B (8-channel), RTC_A, and three-channel DMA-enabling precise analog thresholding and time-stamped event capture without ADC overhead.

FAQ
What is the maximum system clock frequency supported by the MSP430F5239IZQE?
The MSP430F5239IZQE supports a maximum system clock frequency of 25 MHz, achieved via its digitally controlled oscillator (DCO) and FLL loop. This allows high-speed instruction execution while maintaining ultra-low-power operation in active mode, with typical current draw of 290 µA/MHz at 8 MHz and 3.0 V during flash execution.
Does the MSP430F5239IZQE include an analog-to-digital converter (ADC)?
No, the MSP430F5239IZQE does not include an ADC. It belongs to the MSP430F523x series, which omits the ADC10_A module present in the F524x series. The device retains COMP_B (8-channel comparator), RTC_A, and dual USCI interfaces, making it ideal for applications relying on external ADCs or purely digital/analog-threshold-based sensing.
What package type and pin count does the MSP430F5239IZQE use?
The MSP430F5239IZQE uses the MicroStar Junior™ BGA package with 80 pins in a 5 mm × 5 mm body size. This package is shared across the F5239/F5237/F5249/F5247 devices and features a bottom-exposed thermal pad recommended for connection to DVSS to enhance thermal performance and reliability.
How does the MSP430F5239IZQE achieve ultra-low-power operation in standby mode?
The MSP430F5239IZQE achieves 1.9 µA standby current (LPM3) by retaining full RAM content while keeping only the RTC, watchdog, and supply supervisor active. Its low-power oscillator (VLO) and 32-kHz crystal (XT1) options allow flexible trade-offs between accuracy and current draw, and the integrated LDO enables core voltage scaling to minimize static power.
Can the MSP430F5239IZQE be programmed in-system without external voltage?
Yes, the MSP430F5239IZQE supports serial onboard programming (SBW) with no external programming voltage required. Using the TEST/SBWTCK and RSTDVCC/SBWTDIO pins, firmware can be updated in-system via Spy-Bi-Wire interface at standard VCC levels (1.8–3.6 V), simplifying field upgrades and eliminating high-voltage programming circuitry.
