Product details
Overview
MSP430F5635IZQWT from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 256 KB flash, 16 KB + 2 KB RAM, USB 2.0 full-speed interface, dual 12-bit DACs, 12-bit ADC with 16 channels (12 external, 4 internal), four 16-bit timers, two USCI modules (UART/IrDA/SPI/I²C), and RTC with battery backup - deployed in portable sensor systems and handheld meters requiring extended battery life.
For engineers reviewing the MSP430F5635IZQWT datasheet, MSP430F5635IZQWT pinout, MSP430F5635IZQWT application, or MSP430F5635IZQWT equivalent, key selection criteria include USB integration without external PHY, LPM3.5 RTC operation at 1.1 µA, 3 µs wake-up from standby, 74 I/O pins in MicroStar Junior BGA, and absence of integrated DACs in comparable family members.
Technical Context
The MSP430F5635IZQWT implements a 16-bit RISC CPUXV2 core with constant generators and hardware multiplier supporting 32-bit operations. Its unified clock system integrates FLL, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz), enabling precise frequency stabilization and flexible low-power timing.
Power management includes a fully integrated programmable LDO, supply voltage supervisor (SVS), brownout reset (BOR), and five low-power modes (LPM0–LPM4.5). The device supports DMA-driven peripheral operation and features a dedicated USB power system with integrated 3.3-V/1.8-V regulators and USB-PLL.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5636IZQWT | 128 KB flash, same 74-I/O ZQW package, identical peripherals except reduced flash - no DACs, same USB/ADC/timers. | Suitable for cost-sensitive designs where firmware size <128 KB and DAC functionality is unused. | Select when flash budget permits reduction and DACs are unnecessary; maintains pin compatibility and USB/RTC feature set. |
| MSP430F5638IPZ | 256 KB flash, 100-pin LQFP (14 mm × 14 mm), same core/peripherals - adds dual 12-bit DACs and full 74-I/O support. | Preferred for prototyping or space-tolerant designs needing through-hole or larger-pitch assembly. | Choose for development boards or industrial controls where BGA rework is impractical; retains full DAC and USB capability. |

FAQ
What is the package type and ball count for MSP430F5635IZQWT?
The MSP430F5635IZQWT uses the MicroStar Junior™ BGA package (ZQW) with 113 balls in a 7 mm × 7 mm footprint and 0.5 mm pitch. This package is optimized for compact, high-density PCB layouts typical in handheld and portable instrumentation where space is constrained.
Does MSP430F5635IZQWT include integrated DACs?
No, the MSP430F5635IZQWT does not include integrated DACs. Per TI SLAS650G Table 6-1, DAC12_A channel count is "–" for MSP430F5635, distinguishing it from MSP430F5638/F5637 which include two 12-bit DACs. This omission reduces silicon cost while retaining full USB, ADC, and timer functionality.
What is the minimum supply voltage for active operation of MSP430F5635IZQWT?
The MSP430F5635IZQWT operates from 1.8 V to 3.6 V. At 1.8 V, it supports full functionality including USB (with internal regulators), ADC, and 20-MHz system clock - enabling operation directly from single-cell Li-ion or two-cell alkaline supplies without external boost conversion.
How does the USB interface of MSP430F5635IZQWT differ from standard microcontroller USB implementations?
The MSP430F5635IZQWT integrates a full-speed USB 2.0 PHY, 3.3-V and 1.8-V USB power regulators, and USB-PLL - eliminating need for external transceivers, LDOs, or clock sources. It supports eight endpoints and complies with USB 2.0 specification, enabling CDC, HID, and vendor-class device operation out-of-box.
What low-power mode achieves the lowest current draw with RTC active on MSP430F5635IZQWT?
LPM3.5 (shutdown RTC mode) achieves 1.1 µA at 3.0 V with RTC running from 32-kHz crystal - the lowest active-current mode supporting timekeeping. This mode retains RAM and RTC registers while disabling CPU, flash, and most peripherals, making it optimal for long-duration timestamped logging.
