Product details
Overview
MSP430F6632IZQWR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 256 KB flash, 16 KB + 2 KB RAM, USB 2.0 full-speed interface, four 16-bit timers, two USCI modules (UART/IrDA/SPI/I²C), RTC with battery backup, and 74 GPIO pins in a 113-ball MicroStar Junior BGA package. It targets portable metering and sensor systems requiring long battery life and integrated analog peripherals.
For engineers reviewing the MSP430F6632IZQWR datasheet, MSP430F6632IZQWR pinout, MSP430F6632IZQWR application, or MSP430F6632IZQWR equivalent, key selection criteria include USB integration, LPM3.5 RTC operation at 1.1 µA, 12-bit ADC channel count, absence of on-chip DAC/ADC input channels, and ZQW package compatibility with high-density PCB layouts.
Technical Context
The MSP430F6632IZQWR implements a 16-bit RISC CPU with constant generators and a digitally controlled oscillator (DCO), enabling 3 µs wake-up from LPM3 standby. Its unified clock system integrates FLL stabilization, VLO and REFO internal sources, XT1 (32 kHz), and XT2 (up to 32 MHz) crystal support.
Power management includes an integrated LDO with programmable core voltage, supply supervision, brownout detection, and five low-power modes-LPM0–LPM4.5-with LPM3.5 delivering RTC operation at 1.1 µA and LPM4.5 at 0.3 µA, both with full RAM retention.

Pinout & Package
MicroStar Junior™ BGA (ZQW) package: 113-ball, 7 mm × 7 mm, 0.5-mm pitch, bottom-side thermal pad. Pinout conforms to TI's standard 100-pin PZ and 113-ball ZQW mapping for MSP430F663x family; full signal assignment requires reference to Figure 7-4 (ZQW pin diagram) and Section 7.2 (Signal Descriptions) of SLAS566G.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST/NMI/SBWTDIO | Reset / Non-maskable interrupt / Spy-Bi-Wire debug I/O | Single-pin multifunction interface supporting device reset, NMI assertion, and 2-wire JTAG debugging |
| TEST/SBWTCK | Spy-Bi-Wire test clock | Dedicated debug clock input for SBW programming and emulation; not shared with GPIO |
| AVCC / AVSS | Analog power supply / ground | Separate 3.0-V analog domain rails decoupled from digital DVCC/DVSS to minimize noise coupling into ADC/DAC paths |
| USB_DP / USB_DM | USB differential data pair | Full-speed USB 2.0 physical layer signals routed with controlled 90-Ω differential impedance and ESD protection per USB spec |
| P1.x – P9.x | General-purpose I/O ports | 74 total pins across nine ports; each supports interrupt-on-change, programmable pullup/pulldown, and multiple peripheral mappings (e.g., USCI, timer capture) |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power RTC operation | LPM3.5 mode enables real-time clock with 32-kHz crystal at 1.1 µA, preserving timekeeping during deep sleep without external RTC IC |
| Integrated USB subsystem | Eliminates need for external USB transceiver or level-shifting; includes PHY, power regulation, PLL, and endpoint buffers in one die |
| Flexible clock architecture | Combines FLL, VLO, REFO, XT1, and XT2 sources to support precise timing across operating modes and temperature ranges |
| Hardware DMA controller | 6-channel DMA offloads CPU during memory-to-peripheral transfers (e.g., ADC → RAM, USB → buffer), reducing active-mode duration |
| Unified low-power design | Five LPMs with sub-µA shutdown (LPM4.5) and fast 3-µs wake-up enable duty-cycled sensing applications with <1% active time |
Applications
| Smart Energy Meters | Portable Medical Sensors |
|---|---|
Use Scenario: Battery-powered electricity/water/gas meters logging consumption data hourly and transmitting via RF or PLC. IC Role / Device Role / Timing Role: Main controller executing metrology firmware, managing RTC calendar, buffering data in RAM, and initiating USB-based firmware updates.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F6632IPZ | Same core, memory, and peripherals but in 100-pin LQFP (14 mm × 14 mm) instead of 113-ball ZQW BGA | Requires larger PCB area and different layout rules; lacks ZQW's high I/O density and thermal pad | Select for prototyping or lower-volume production where BGA assembly is unavailable or cost-prohibitive |
| MSP430F6635IZQW | Identical ZQW package and USB/RTC/timer features, but adds 12-channel 12-bit ADC (12 ext + 4 int) and removes DACs | Enables analog sensor acquisition without external ADC; unsuitable where DAC output is required | Select when analog front-end integration is needed and DAC functionality is unnecessary |
Compared with MSP430F6632IPZ, the MSP430F6632IZQWR offers superior board-level miniaturization and thermal performance in space-constrained designs; compared with MSP430F6635IZQW, it trades ADC capability for simplified analog BOM and identical USB/RTC functionality in legacy metering platforms.

FAQ
What is the maximum system clock frequency supported by the MSP430F6632IZQWR?
The MSP430F6632IZQWR supports a maximum system clock frequency of 20 MHz, achieved using the integrated digitally controlled oscillator (DCO) with FLL stabilization or external high-frequency crystals up to 32 MHz on XT2. This frequency enables real-time processing of USB transactions, timer-based PWM generation, and sensor sampling at rates compatible with its 200 ksps ADC (when present in other variants).
Does the MSP430F6632IZQWR include an integrated ADC or DAC?
No, the MSP430F6632IZQWR does not include an integrated ADC or DAC. As confirmed in Table 6-1 (Device Comparison) of the SLAS566G datasheet, this variant has "–" entries for both ADC12_A and DAC12_A channels-distinguishing it from MSP430F6638/F6636 (which include ADC) and MSP430F6638/F6637 (which include dual DACs). Analog signal acquisition requires external components.
What are the low-power mode current specifications for the MSP430F6632IZQWR?
The MSP430F6632IZQWR achieves 1.8 µA in LPM3 (standby with watchdog and crystal), 1.1 µA in LPM3.5 (RTC active with crystal), and 0.3 µA in LPM4.5 (full shutdown with RAM retention)-all measured at 3.0 V. These values are specified in Section 1 (Features) and validated in Section 8.5 of SLAS566G, enabling decade-long battery life in always-on sensing nodes.
Is the MSP430F6632IZQWR pin-compatible with other MSP430F663x devices in the ZQW package?
Yes, the MSP430F6632IZQWR shares identical pinout and ball assignment with all MSP430F663x devices offered in the 113-ball ZQW package-including MSP430F6636IZQW and MSP430F6634IZQW-as documented in Figure 7-4 and Section 7.1 of SLAS566G. This allows hardware reuse across variants differing only in flash size, ADC presence, or DAC inclusion.
What debug interface does the MSP430F6632IZQWR support?
The MSP430F6632IZQWR supports Spy-Bi-Wire (SBW), a 2-wire JTAG variant using RST/NMI/SBWTDIO and TEST/SBWTCK pins. This interface enables full-speed programming, real-time debugging, and flash memory access without requiring a 4-pin JTAG header-reducing PCB footprint and simplifying test fixture design for ZQW-packaged units.
