Product details
Overview
MSP430F5335IZQWT 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, two USCI modules (UART/IrDA/SPI/I²C), four 16-bit timers, RTC with alarm, and up to 74 GPIOs - deployed in battery-powered sensor systems and portable meters.
For engineers reviewing the MSP430F5335IZQWT datasheet, MSP430F5335IZQWT pinout, MSP430F5335IZQWT application, or MSP430F5335IZQWT equivalent, key selection criteria include LPM3 standby current (1.8 µA at 2.2 V), 3 µs wake-up time, MicroStar Junior BGA-113 package compatibility, and absence of on-chip DACs compared to MSP430F5338.
Technical Context
The MSP430F5335IZQWT implements a unified clock system with FLL stabilization, VLO and REFO internal sources, XT1 (32 kHz) and XT2 (up to 32 MHz) crystal support, and programmable core voltage via integrated LDO. Its CPUXV2 core executes instructions in single-cycle mode with constant generators for optimized code density.
Peripherals are memory-mapped and interrupt-driven: ADC12_A supports autoscan across 12 external + 4 internal channels; USCI_A0/A1 provide UART/IrDA/SPI; USCI_B0/B1 support I²C/SPI; Timer_A instances (5/3/3 CC registers) and Timer_B (7 CC) enable PWM, capture, and interval timing; RTC_B includes battery backup and alarm capability.

FAQ
What is the operating voltage range for the MSP430F5335IZQWT?
The MSP430F5335IZQWT operates from 1.8 V to 3.6 V. This wide supply range allows direct interfacing with common lithium coin cells (e.g., CR2032, ~3.0 V) and single-cell Li-ion batteries (2.7–4.2 V with regulator), supporting flexible power architecture in portable devices. The integrated LDO maintains stable VCORE across this input range.
Does the MSP430F5335IZQWT include a hardware DAC?
No, the MSP430F5335IZQWT does not include on-chip DACs. Per the device comparison table in SLAS721F, DAC12_A channels are marked "–" for MSP430F5335 and MSP430F5333, distinguishing them from MSP430F5338/MSP430F5336 which feature dual 12-bit DACs. Analog output must be implemented externally or via PWM filtering.
What package type and pin count does the MSP430F5335IZQWT use?
The MSP430F5335IZQWT uses the MicroStar Junior™ BGA-113 package (7 mm × 7 mm, 0.5 mm pitch). It provides 74 GPIOs plus power, ground, crystal, and debug pins. Pin assignments match other ZQW-family devices (MSP430F5338/5336/5333), enabling layout reuse across variants.
How much flash and RAM memory does the MSP430F5335IZQWT have?
The MSP430F5335IZQWT integrates 256 KB of flash memory and 18 KB of RAM, plus 8 B of battery-backed RAM. This configuration supports substantial firmware (e.g., BLE stack + sensor algorithms) and real-time data buffering - exceeding the 128 KB flash of MSP430F5336IZQWT while matching its RAM size.
What is the typical current draw in standby (LPM3) mode for the MSP430F5335IZQWT?
The MSP430F5335IZQWT draws 1.8 µA typical in LPM3 mode at 2.2 V, with watchdog, crystal oscillator, and full RAM retention active. At 3.0 V, it consumes 2.1 µA typical. This ultra-low quiescent current enables multi-year operation on small batteries in always-on sensor applications.
