Product details
Overview
MSP430F5632IZQWR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller with 256 KB flash, 16 KB + 2 KB RAM, USB 2.0 interface, dual 12-bit DACs, and 74 GPIO pins in a 113-pin MicroStar Junior™ BGA package. It operates from 1.8 V to 3.6 V and delivers 270 µA/MHz active current at 8 MHz, enabling battery-powered sensor systems and portable meters.
For engineers reviewing the MSP430F5632IZQWR datasheet, MSP430F5632IZQWR pinout, MSP430F5632IZQWR application, or MSP430F5632IZQWR equivalent, key selection criteria include USB integration, RTC with battery backup, low-power mode wake-up time (3 µs), ADC channel count (none - confirmed absent per Device Comparison Table 6-1), and BGA package compatibility for space-constrained embedded designs.
Technical Context
The MSP430F5632IZQWR implements a 16-bit RISC CPU with constant generators and a unified clock system featuring FLL stabilization, VLO, REFO, XT1 (32-kHz), and XT2 (up to 32 MHz). Its power architecture includes an integrated LDO with programmable core voltage and brownout detection.
It integrates two USCI modules (USCI_A0/A1 for UART/IrDA/SPI; USCI_B0/B1 for I²C/SPI), four 16-bit timers (TA0 with 5 CC registers; TA1/TA2 with 3 each; TB0 with 7), hardware multiplier (MPY32), 6-channel DMA, and RTC_B with alarm and battery backup support - but no ADC12_A or DAC12_A peripherals, as explicitly omitted in Device Comparison Table 6-1 for this variant.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5632IPZ | Same core, flash, RAM, and peripherals, but in 100-pin LQFP (14 mm × 14 mm) instead of 113-pin ZQW BGA. | LQFP simplifies prototyping and rework; BGA offers higher I/O density and better thermal performance in production. | Select MSP430F5632IPZ for development or low-volume assembly; choose MSP430F5632IZQWR for space-constrained, high-reliability production. |
| MSP430F5636IZQWR | Includes 12-bit ADC12_A (12 external + 4 internal channels) and dual DAC12_A; otherwise identical package, USB, and timer resources. | Required when analog signal acquisition (e.g., sensor voltage, thermistor) is needed on same die - MSP430F5632IZQWR lacks ADC/DAC. | Choose MSP430F5636IZQWR if analog front-end integration is essential; MSP430F5632IZQWR suits digital-only or externally conditioned signal paths. |
Compared with MSP430F5632IPZ, the MSP430F5632IZQWR enables smaller PCB footprints and improved thermal dissipation, while MSP430F5636IZQWR adds on-chip analog conversion capability - making it the only direct alternative when ADC functionality is mandatory.

FAQ
Does MSP430F5632IZQWR include an integrated analog-to-digital converter (ADC)?
No, the MSP430F5632IZQWR does not include ADC12_A. Per TI's Device Comparison Table 6-1, this variant explicitly lists "–" under the ADC12_A (Ch) column, distinguishing it from family members like MSP430F5636IZQWR. Designers requiring analog input must use external ADCs or select an ADC-equipped variant.
What is the maximum operating frequency of MSP430F5632IZQWR?
The MSP430F5632IZQWR supports a maximum system clock (MCLK) of 20 MHz, enabled by its integrated FLL and XT2 oscillator supporting crystals up to 32 MHz. This allows deterministic real-time execution for USB, timer, and communication tasks within its ultra-low-power envelope.
Is MSP430F5632IZQWR pin-compatible with other MSP430F563x ZQW-packaged devices?
Yes, the MSP430F5632IZQWR shares identical pinout and package dimensions (113-pin MicroStar Junior™ BGA, 7 mm × 7 mm) with other ZQW variants including MSP430F5636IZQWR and MSP430F5630IZQWR, enabling layout reuse across family members with differing peripheral sets.
What USB speed and endpoint configuration does MSP430F5632IZQWR support?
The MSP430F5632IZQWR supports full-speed USB 2.0 (12 Mbps) with eight configurable endpoints (four IN, four OUT), integrated USB-PHY, and dedicated 3.3-V/1.8-V power regulation - enabling HID, CDC, and custom class implementations without external transceivers.
How does the RTC_B module function in MSP430F5632IZQWR during power loss?
The RTC_B module in MSP430F5632IZQWR maintains timekeeping during main power loss via its dedicated battery backup switch, which automatically routes VBAT to the RTC domain. It retains calendar, alarm, and counter values in backup RAM, waking the system on alarm events even in LPM4.5 (0.3 µA).
