Product details
Overview
MSP430F5508IZQE from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller with integrated full-speed USB 2.0 PHY, 16 KB flash, 4 KB + 2 KB RAM, 10-bit ADC (8 channels: 6 external, 2 internal), two USCI modules (UART/IrDA/SPI/I²C), four 16-bit timers, RTC, hardware multiplier, and DMA - designed for battery-powered sensor systems and USB-connected data loggers.
For engineers reviewing the MSP430F5508IZQE datasheet, MSP430F5508IZQE pinout, MSP430F5508IZQE application, or MSP430F5508IZQE equivalent, key selection criteria include USB PHY integration, 80-pin MicroStar Junior™ BGA package, LPM4.5 shutdown current (0.18 µA), RTC alarm capability, and dual USCI support with port-mapped flexibility on P4.
Technical Context
The MSP430F5508IZQE implements a unified clock system with FLL stabilization, dual crystal oscillators (XT1 for 32-kHz RTC, XT2 up to 32 MHz), VLO and REFO internal sources, and programmable LDO core regulation. Its CPUXV2 core executes instructions at up to 25 MHz with constant generators for optimized code density.
Peripherals are managed via a port mapping controller (PMC) on Port 4, enabling dynamic assignment of USCI_A1/USCI_B1 signals to P4 pins - critical for routing USB, UART, I²C, or SPI in space-constrained BGA layouts without fixed pin dependencies.

Applications
| USB-Powered Sensor Node | Industrial Data Logger |
|---|---|
|
Use Scenario: Compact environmental monitor powered directly from USB bus, logging temperature/humidity/pressure at 10-second intervals. IC Role / Device Role / Timing Role: MSP430F5508IZQE acts as main controller, ADC manager, RTC time-stamper, and USB device endpoint - handling all sensing, storage, and host communication. Use Value: Integrated USB PHY and LPM4.5 enable true bus-powered operation with <1 µA standby draw between samples, extending field deployment life without batteries. |
Use Scenario: Ruggedized field logger capturing analog sensor data (e.g., strain gauges, thermocouples) and storing timestamps in flash for later USB retrieval. IC Role / Device Role / Timing Role: MCU executes deterministic sampling via TA0-triggered ADC sequences, stores results with RTC timestamps in flash, and presents as mass-storage-class USB device. Use Value: Hardware RTC alarm wakes MCU precisely every 5 minutes; 16 KB flash + 6 KB RAM supports >10,000 timestamped samples before host transfer. |
| Wireless Headset Bridge | USB HID Peripheral |
|
Use Scenario: Bluetooth-to-USB bridge in headset accessories, converting audio control commands (play/pause/volume) into USB HID reports for PC/Mac. IC Role / Device Role / Timing Role: MSP430F5508IZQE serves as protocol translator: receives UART commands from BT SoC, formats HID reports, and delivers them via full-speed USB interrupt endpoints. Use Value: Dual USCI support allows concurrent UART (BT link) and USB HID operation; low active current (195 µA/MHz) minimizes heat in sealed plastic enclosure. |
Use Scenario: Programmable USB keyboard/mouse emulator for test automation, sending keystrokes or mouse movements to host via standard HID descriptors. IC Role / Device Role / Timing Role: MCU enumerates as USB HID device, processes GPIO scan matrix or encoder inputs, and transmits report packets via endpoint 1 IN. Use Value: On-chip USB descriptor engine and endpoint buffers eliminate external USB controller; 80-pin BGA provides ample GPIO for 64-key matrix + status LEDs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power USB microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5509IZQE | 24 KB flash, same peripherals, identical 80-pin ZQE package and pinout | Supports larger firmware images (e.g., USB CDC ACM + custom HID descriptors) without changing PCB layout | Select when firmware size exceeds 16 KB but USB/RTC/ADC requirements match MSP430F5508IZQE |
| MSP430F5510IZQE | 32 KB flash, 47 I/O pins (vs. 31), adds two external ADC channels (10 ext, 2 int) | Suitable for multi-sensor systems requiring >6 analog inputs or additional GPIO for expansion interfaces | Choose when higher I/O count or extended ADC channel count is required - same USB/RTC/power architecture |
Compared with MSP430F5509IZQE and MSP430F5510IZQE, the MSP430F5508IZQE offers optimal balance of USB integration, ultra-low-power operation, and compact footprint for cost-sensitive, single-sensor USB devices where 16 KB flash suffices.

FAQ
What USB speed and device class does the MSP430F5508IZQE support?
The MSP430F5508IZQE supports full-speed USB 2.0 (12 Mbps) with an integrated PHY and complies with USB 2.0 specification. It natively supports multiple device classes including HID, CDC ACM, and MSC via firmware - no external USB controller is needed. The MSP430F5508IZQE uses its built-in USB-PLL and dual power rails (3.3 V and 1.8 V) to meet electrical compliance requirements.
Does the MSP430F5508IZQE require external crystals for RTC operation?
Yes - the MSP430F5508IZQE requires a 32.768-kHz crystal connected to P5.4/XIN and P5.5/XOUT for accurate RTC operation in low-power modes. While it includes internal VLO and REFO oscillators, only the XT1 crystal provides the ±20 ppm stability needed for calendar-mode RTC functionality. The MSP430F5508IZQE's RTC_A module relies on this crystal for timekeeping during LPM3/LPM4.
How many analog input channels does the ADC in the MSP430F5508IZQE support?
The MSP430F5508IZQE integrates the ADC10_A module with 8 total input channels: 6 external analog inputs (A0–A5 mapped to P6.0–P6.5) and 2 internal references (VeREF+ and VeREF− on P5.0/P5.1). It achieves 200 ksps sampling rate with configurable window comparator and burst conversion modes - all managed autonomously via timer triggers without CPU intervention.
Is the MSP430F5508IZQE pin-compatible with other ZQE-package MSP430F55xx devices?
Yes - the MSP430F5508IZQE shares identical 80-pin MicroStar Junior™ BGA (ZQE) mechanical footprint and pinout with MSP430F5509IZQE and MSP430F5510IZQE. All three support the same signal assignments per pin, including USB DP/DM, XT1, JTAG/SBW, and PMC-enabled USCI routing on P4. This enables direct hardware reuse across firmware variants scaling flash from 16 KB to 32 KB.
What is the lowest power consumption mode supported by the MSP430F5508IZQE?
The MSP430F5508IZQE supports LPM4.5 (shutdown mode) with 0.18 µA typical current draw at 3 V - the lowest power state that retains only register context (no RAM). For applications needing full RAM retention, LPM4 draws 1.1 µA at 3 V. Both modes support fast wake-up (<10 µs) via external interrupt or RTC alarm, making the MSP430F5508IZQE ideal for intermittent-sensing applications.
