Product details
Overview
MSP430F5328IZQER from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 128 KB flash, 10 KB RAM, integrated 3.3-V LDO, 12-bit ADC (10 external + 2 internal channels), four 16-bit timers (TA0/TA1/TA2/TB0), two USCIs (UART/IrDA/SPI/I²C), RTC, and hardware multiplier - designed for battery-powered sensor systems and data loggers requiring sub-2 µA standby current and 3.5 µs wake-up.
For engineers reviewing the MSP430F5328IZQER datasheet, MSP430F5328IZQER pinout, MSP430F5328IZQER application, or MSP430F5328IZQER equivalent, key selection criteria include its 47 I/O count in MicroStar Junior BGA (80-pin), LPM3 current of 1.9 µA at 3 V, 12-bit ADC autoscan capability, and dual-USCI support for concurrent wired communication interfaces.
Technical Context
The MSP430F5328IZQER implements a unified clock system with FLL stabilization, programmable LDO core regulation, and flexible low-power mode control (LPM0–LPM4.5). Its CPUXV2 core executes instructions at up to 25 MHz with constant generators for optimized code density.
Peripheral integration includes three-channel DMA, comparator B (8 channels), CRC16 module, and port mapping control enabling dynamic signal routing across 47 GPIOs - all operating within 1.8–3.6 V supply range while maintaining full RAM retention in LPM4.

FAQ
What is the maximum system clock frequency supported by the MSP430F5328IZQER?
The MSP430F5328IZQER supports a maximum system clock (MCLK) frequency of 25 MHz, achieved using the FLL with XT2 high-frequency crystal input (up to 32 MHz) or internal DCO calibration. This allows real-time execution of time-critical tasks such as high-speed ADC sampling or protocol timing without external clock sources.
Does the MSP430F5328IZQER support hardware debugging via JTAG or Spy-Bi-Wire?
Yes, the MSP430F5328IZQER supports Spy-Bi-Wire (SBW) debugging through the RST/NMI/SBWTDIO and TEST/SBWTCK pins, enabling full-featured programming and real-time debugging with TI's MSP-FET and compatible tools - no dedicated JTAG header required.
How many external analog input channels does the ADC12_A module support on the MSP430F5328IZQER?
The ADC12_A module on the MSP430F5328IZQER supports 10 external analog input channels (A0–A9), plus 2 internal sources (temperature sensor and VREF generator), as confirmed in the Device Comparison table and functional block diagram for ZQE-package variants.
What is the function of the PU.0 and PU.1 pins on the MSP430F5328IZQER?
PU.0 and PU.1 are dedicated I/O pins supplied by the LDOO rail - electrically isolated from the main DVCC domain. They provide noise-immune GPIO for interfacing with sensitive analog or isolated digital circuits, and are documented in Section 7.2 Signal Descriptions and Figure 7-3 pinout.
Is the MSP430F5328IZQER pin-compatible with other members of the F532x family in the ZQE package?
Yes, the MSP430F5328IZQER shares identical pinout, ball assignment, and electrical characteristics with MSP430F5326IZQER and MSP430F5324IZQER in the ZQE package - enabling drop-in replacement within the same memory/peripheral tier, subject to firmware validation for flash/RAM usage.
