Overview
MSP430F5335IZQWR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with integrated 3.3-V LDO, 256 KB flash, 18 KB RAM, 12-bit ADC (200 ksps, 16 channels), dual 12-bit DACs, RTC, four 16-bit timers, two USCIs (UART/IrDA/SPI/I²C), and 74 GPIO pins - deployed in battery-powered sensor systems and portable measurement devices.
For engineers reviewing the MSP430F5335IZQWR datasheet, MSP430F5335IZQWR pinout, MSP430F5335IZQWR application, or MSP430F5335IZQWR equivalent, key selection criteria include standby current (1.8 µA at 2.2 V), wake-up time (3 µs), ADC resolution and scan capability, DAC synchronization support, and MicroStar Junior™ BGA (113-pin) package compatibility for high-density PCB layouts.
Technical Context
The MSP430F5335IZQWR implements a unified clock system with FLL stabilization, VLO and REFO internal sources, XT1 (32 kHz), and XT2 (up to 32 MHz), enabling flexible low- and high-frequency operation. Its power-management subsystem integrates a programmable LDO core regulator, supply supervision, brownout detection, and five low-power modes (LPM0–LPM4.5).
Peripherals include a 6-channel DMA controller, hardware multiplier for 32-bit operations, CRC16 module, and RTC_B with alarm and battery backup. The device supports serial onboard programming without external voltage and features Schmitt-trigger inputs across all general-purpose I/O ports.

FAQ
What is the maximum system clock frequency supported by the MSP430F5335IZQWR?
The MSP430F5335IZQWR supports a maximum system clock frequency of 20 MHz. This is achieved using the FLL-controlled DCO or external high-frequency crystals up to 32 MHz on XT2 - though the CPU and peripheral timing specifications are validated up to 20 MHz per the device's recommended operating conditions. The MSP430F5335IZQWR maintains full functionality and timing compliance within this range.
Does the MSP430F5335IZQWR include a hardware real-time clock (RTC) module?
Yes, the MSP430F5335IZQWR integrates the RTC_B module with calendar/timekeeping, alarm capability, and battery backup support. It operates independently in LPM3.5 mode with crystal accuracy and retains state via VBAK/VBAT supply - enabling uninterrupted timekeeping during main power loss. The MSP430F5335IZQWR RTC_B is fully documented in Section 9.12.12 of the SLAS721F datasheet.
How many analog-to-digital converter (ADC) input channels does the MSP430F5335IZQWR provide?
The MSP430F5335IZQWR features a 12-bit ADC12_A module with 16 total input channels: 12 external analog inputs (A0–A11) and 4 internal sources (temperature sensor, VCC/2, VeREF+, and AVCC). Channel autoscan allows sequential conversion without CPU intervention - a key capability confirmed in the Device Comparison table and Section 8.34 of the MSP430F5335IZQWR datasheet.
Is the MSP430F5335IZQWR pin-compatible with other devices in the MSP430F533x family?
Yes, the MSP430F5335IZQWR shares identical pinout and package dimensions with MSP430F5338IZQWR, MSP430F5336IZQWR, and MSP430F5333IZQWR in the MicroStar Junior™ BGA (ZQW) variant. All four devices use the same 113-ball layout per Figure 7-3 and Table 7-1 - enabling hardware reuse across flash/RAM/DAC configurations without PCB redesign.
What debug interface does the MSP430F5335IZQWR support?
The MSP430F5335IZQWR supports Spy-Bi-Wire (SBW) and JTAG via the RST/NMI/SBWTDIO and TEST/SBWTCK pins. SBW is the primary 2-wire debug interface for programming and real-time emulation, while full JTAG is available through PJ.0–PJ.3. Both interfaces are compatible with TI's MSP-FET and standard IDEs like Code Composer Studio - verified in Sections 7.2 and 9.8 of the MSP430F5335IZQWR datasheet.
