Product details
Overview
MSP430F5514IZQER from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with integrated USB 2.0 PHY, four 16-bit timers (TA0/TA1/TA2/TB0), two USCI modules (UART/I²C/SPI), RTC, hardware multiplier, and 3-channel DMA. It features 64 KB flash, 6 KB + 2 KB RAM, operates from 1.8 V to 3.6 V, and delivers 1.4 µA standby current at 3.0 V - optimized for battery-powered USB-connected sensor nodes and data loggers.
For engineers reviewing the MSP430F5514IZQER datasheet, MSP430F5514IZQER pinout, MSP430F5514IZQER application, or MSP430F5514IZQER equivalent, key selection criteria include its MicroStar Junior BGA-80 package, 47 I/O pins, absence of integrated 12-bit ADC (unlike F552x variants), USB 2.0 full-speed support with on-chip LDO/PLL, and LPM4.5 shutdown current of 0.18 µA.
Technical Context
The MSP430F5514IZQER implements a 16-bit RISC CPUXV2 core with constant generators and unified clock system featuring FLL stabilization, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz). Its power management includes programmable LDO core regulation, SVS/SVM monitoring, and five low-power modes (LPM0–LPM4.5) with 3.5 µs wake-up from LPM3.
Peripherals are mapped via port-select registers and supported by DMA-driven USCI transfers, timer capture/compare shadow registers, and RTC alarm functionality. The device lacks ADC12_A but retains COMP_B (8-channel comparator), CRC16 engine, and EEM (enhanced erase module) for flash management.

Applications
| USB-Powered Sensor Node | Data Logger with RTC Wake-Up |
|---|---|
Use Scenario: Compact environmental monitor powered directly from USB bus, sampling temperature/humidity every 10 seconds and uploading data on demand. IC Role / Device Role: Central MCU managing sensor I²C reads, RTC timestamping, USB bulk transfers, and LPM3 sleep between samples. Use Value: 1.4 µA LPM3 current extends coin-cell backup life beyond 5 years; integrated USB PHY avoids external IC cost and layout complexity. |
Use Scenario: Battery-operated field logger recording voltage/current waveforms at 1 kHz, waking only at scheduled intervals to store data to flash and transmit via USB. IC Role / Device Role: Real-time data acquisition controller with DMA-driven ADC sampling (via external ADC), flash logging, and RTC-triggered wake-up. Use Value: 3.5 µs wake-up from LPM3 ensures minimal latency on schedule; 64 KB flash stores >100k samples before upload. |
| Portable Diagnostic Tool | Industrial USB Configuration Adapter |
Use Scenario: Handheld tool that connects to legacy RS-232/RS-485 equipment via level shifter and exposes virtual COM port over USB to PC. IC Role / Device Role: Protocol bridge MCU running UART-to-USB CDC firmware, managing flow control, buffer management, and USB enumeration. Use Value: Dual USCI modules enable simultaneous UART and USB operation; hardware multiplier accelerates CRC calculation for command validation. |
Use Scenario: DIN-rail mounted adapter configuring PLC I/O modules via Modbus RTU over RS-485 and exposing settings via USB HID interface. IC Role / Device Role: Field-configurable interface translator with nonvolatile parameter storage, USB HID report handling, and watchdog-monitored RS-485 communication. Use Value: 47 GPIOs support LED indicators, DIP switches, and isolated RS-485 control lines; LPM4.5 mode maintains configuration state during power loss. |
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 |
|---|---|---|---|
| MSP430F5529IPN | 80-pin LQFP, 128 KB flash, 12-bit ADC (200 ksps, 16 ch), 63 I/O, same USB/USCI/timer set | Requires external ADC for analog sensing; larger footprint and higher active current | Select when higher flash, ADC integration, or through-hole prototyping is needed |
| MSP430FR5969IRGCR | Ferroelectric RAM (64 KB FRAM), no USB PHY, 48 I/O, 12-bit ADC, LPM3.5 = 0.4 µA | Needs external USB-UART bridge; FRAM enables unlimited write endurance for logging | Select when frequent flash writes or USB host interface is not required |
Compared with MSP430F5529IPN, the MSP430F5514IZQER trades ADC and flash capacity for smaller BGA packaging and lower standby current; versus MSP430FR5969IRGCR, it provides native USB connectivity at the cost of FRAM endurance and higher LPM3 current.

FAQ
Does MSP430F5514IZQER include an integrated 12-bit analog-to-digital converter?
No, the MSP430F5514IZQER does not integrate the ADC12_A module. This distinguishes it from the MSP430F552x series (e.g., MSP430F5529), which includes a 12-bit, 200-ksps ADC with autoscan. The MSP430F5514IZQER retains the 8-channel Comparator_B but relies on external ADCs or digital sensors for analog measurement tasks.
What is the package type and ball pitch of MSP430F5514IZQER?
The MSP430F5514IZQER uses the MicroStar Junior™ BGA-80 (ZQE) package: 5 mm × 5 mm body size with 0.5-mm ball pitch. It is a RoHS-compliant, near-chip-scale package requiring controlled-depth solder paste and reflow profiling per TI SZZA039 application note.
Can MSP430F5514IZQER operate without an external crystal?
Yes, the MSP430F5514IZQER can operate using its internal VLO (10 kHz typical) or REFO (32.768 kHz trimmed) oscillators for basic timing and LPM3 operation. However, USB 2.0 compliance requires precise 48-MHz clock generation, which mandates either an external 4-MHz crystal with USB-PLL multiplication or a 48-MHz external clock source on XT2.
How many USB endpoints does MSP430F5514IZQER support?
The MSP430F5514IZQER supports eight bidirectional USB endpoints (four IN, four OUT), configurable as control, interrupt, bulk, or isochronous pipes. Endpoint 0 is reserved for standard device enumeration; endpoints 1–7 are user-configurable via USBADDR and USBIE registers in firmware.
Is MSP430F5514IZQER pin-compatible with other devices in the MSP430F55xx family?
No, the MSP430F5514IZQER in ZQE package is not pin-compatible with LQFP (e.g., MSP430F5514IPN) or VQFN (e.g., MSP430F5514IRGC) variants. While functional peripherals match within the F551x subgroup, ball assignments, power domain routing, and I/O multiplexing differ significantly across packages - requiring unique PCB layout for each.
