Product details
Overview
MSP430F5324IZQE from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 64 KB flash, 6 KB RAM, integrated 3.3-V LDO, 12-bit ADC (10 external + 2 internal channels), two USCI modules (UART/IrDA/SPI/I²C), four 16-bit timers (TA0/TA1/TA2/TB0), RTC, and hardware multiplier - designed for battery-powered sensor systems and data loggers operating from 1.8 V to 3.6 V.
For engineers reviewing the MSP430F5324IZQE datasheet, MSP430F5324IZQE pinout, MSP430F5324IZQE application, or MSP430F5324IZQE equivalent, this page delivers verified specifications, package mapping to MicroStar Junior™ BGA (80-pin), I/O count (47), low-power mode currents (1.1 µA in LPM4), wake-up time (3.5 µs), and validated alternative parts for design continuity.
Technical Context
The MSP430F5324IZQE implements a unified clock system with FLL stabilization, dual crystal support (XT1 up to 32 kHz, XT2 up to 32 MHz), and three internal sources (VLO, REFO, DCO). Its power architecture integrates a programmable LDO core regulator with supply supervision, brownout detection, and five low-power modes (AM, LPM3, LPM4, LPM4.5) optimized for intermittent sensing duty cycles.
Peripherals include a 12-bit ADC with autoscan and internal reference, comparator B (8 channels), DMA controller (3-channel), and dual USCI modules - each supporting independent protocols (USCI_A: UART/IrDA/SPI; USCI_B: I²C/SPI) - enabling concurrent serial communication without CPU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with constant generators and 25-MHz max system clock - enables efficient C code execution and deterministic real-time response. |
| Memory | 64 KB flash + 6 KB RAM (8 KB + 2 KB configuration) - supports firmware updates in-field and retains full context during LPM3/LPM4 standby. |
| ADC | 12-bit SAR ADC with 10 external + 2 internal input channels, 200 ksps sample rate, and autoscan - suitable for multi-sensor analog front-end acquisition. |
| Low-Power Modes | LPM4 draws 1.1 µA at 3 V; LPM4.5 draws 0.18 µA - extends coin-cell battery life to years in periodic wake-up applications. |
| Timers | Four 16-bit timers: TA0 (5 CC), TA1 (3 CC), TA2 (3 CC), TB0 (7 CC shadow registers) - supports PWM generation, input capture, and RTC calendar functions. |
| Communication | Two USCI modules: USCI_A0/A1 (UART/IrDA/SPI), USCI_B0/B1 (I²C/SPI) - allows simultaneous wired sensor bus (I²C) and host interface (UART). |
| Supply | Integrated 3.3-V LDO with programmable core voltage; operates from 1.8 V to 3.6 V - eliminates external regulator in space-constrained designs. |
Pinout & Package
MicroStar Junior™ BGA package (80-ball, 5 mm × 5 mm, 0.5-mm pitch) with exposed thermal pad connected to VSS. Pin mapping follows TI's standardized ZQE ballout for the MSP430F532x family.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P1.0/TA0CLK/ACLK | Port 1 bit 0 / Timer A0 clock / Auxiliary clock input | Configurable as GPIO or dedicated clock source for timer subsystem and RTC; supports 32-kHz crystal connection. |
| P5.4/XIN & P5.5/XOUT | Crystal oscillator input/output | Connects to 32-kHz watch crystal for RTC operation; requires external load capacitors per layout guidelines. |
| RST/NMI/SBWTDIO | Reset / Non-maskable interrupt / Spy-Bi-Wire debug I/O | Single-pin JTAG-compatible debug interface; enables programming and real-time debugging without dedicated pins. |
| LDOO & LDOI | LDO output and input rails | LDOO supplies Port U (PU.0/PU.1); LDOI connects to DVCC - defines internal power domain separation for I/O and core. |
| VSSU | Port U ground | Dedicated ground return for PU.0/PU.1 - ensures noise isolation for high-impedance analog or low-voltage logic interfaces. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power standby | 1.9 µA in LPM3 with RTC active - enables continuous timekeeping and alarm-triggered wake-up without external RTC chip. |
| Fast wake-up latency | 3.5 µs from LPM3 to active mode - minimizes active-time overhead in event-driven sensor sampling. |
| Hardware multiplier | 32-bit operation support - accelerates FFT, filtering, and cryptographic routines in firmware without software emulation penalty. |
| Integrated LDO | Programmable core voltage regulation - simplifies power design and improves immunity to supply ripple in noisy environments. |
| Dual USCI independence | USCI_A and USCI_B operate concurrently on separate clock domains - permits simultaneous UART telemetry and I²C sensor polling. |

FAQ
What is the maximum system clock frequency supported by the MSP430F5324IZQE?
The MSP430F5324IZQE supports a maximum system clock frequency of 25 MHz, achieved via its digitally controlled oscillator (DCO) stabilized by the FLL loop using either internal references (REFO/VLO) or external crystals (XT2 up to 32 MHz). This frequency enables high-speed ADC sampling (200 ksps) and responsive real-time control without exceeding power budgets in active mode.
Does the MSP430F5324IZQE include an integrated real-time clock (RTC)?
Yes, the MSP430F5324IZQE includes a hardware RTC_A module with calendar functionality and alarm capabilities. It operates in LPM3 using the 32-kHz crystal connected to P5.4/XIN and P5.5/XOUT, retaining full timekeeping and alarm triggering while drawing only 1.9 µA - eliminating need for external RTC ICs in time-stamped data logging applications.
How many general-purpose I/O pins does the MSP430F5324IZQE provide?
The MSP430F5324IZQE provides 47 general-purpose I/O pins, distributed across Ports P1–P8 and PU. This count is confirmed in the Device Comparison table (Table 6-1) and matches the pinout diagrams for ZQE/ZXH/RGC packages. All 47 pins support configurable drive strength, Schmitt-trigger inputs, and peripheral multiplexing.
Is the MSP430F5324IZQE pin-compatible with other devices in the MSP430F532x family?
Yes, the MSP430F5324IZQE is pin-compatible with MSP430F5326IZQE and MSP430F5328IZQE in the same MicroStar Junior™ BGA (ZQE) package. All three share identical ballout, signal mapping, and power/ground pin locations - enabling memory-scalable migration without PCB redesign.
What debug interface does the MSP430F5324IZQE support?
The MSP430F5324IZQE supports Spy-Bi-Wire (SBW), a 2-wire JTAG subset using the RST/NMI/SBWTDIO and TEST/SBWTCK pins. This interface enables full programming, debugging, and boundary-scan capability with minimal PCB footprint - no external debug header required beyond standard test points.
