Product details
Overview
MSP430F5336IZQWR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 128 KB flash, 18 KB RAM, integrated 3.3-V LDO, dual 12-bit DACs, 12-bit ADC with 16 channels (12 external), two USCI modules (UART/IrDA/SPI/I²C), four 16-bit timers, RTC with battery backup, and 74 GPIO pins - deployed in portable sensor systems and battery-powered metering.
For engineers reviewing the MSP430F5336IZQWR datasheet, MSP430F5336IZQWR pinout, MSP430F5336IZQWR application, or MSP430F5336IZQWR equivalent, key selection criteria include LPM3 standby current (1.8 µA at 2.2 V), 3 µs wake-up time from LPM3, 12-bit ADC sampling rate (200 ksps), dual synchronized DAC output capability, and MicroStar Junior™ BGA-113 package compatibility with space-constrained embedded designs.
Technical Context
The MSP430F5336IZQWR 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) for flexible frequency synthesis and low-jitter timing.
Power management includes fully integrated programmable LDO, supply voltage supervision (SVS/SVM), brownout reset, and five low-power modes (LPM0–LPM4.5). Peripheral interconnect uses 6-channel DMA and interrupt-driven I/O mapping across eight ports (P1–P9, PJ, PU) with configurable drive strength and Schmitt-trigger inputs.

FAQ
What is the maximum operating frequency of the MSP430F5336IZQWR?
The MSP430F5336IZQWR supports a maximum system clock (MCLK) frequency of 20 MHz, achieved via its integrated FLL control loop using either internal REFO/VLO or external XT2 crystals up to 32 MHz. This frequency governs CPU execution speed, timer resolution, and peripheral throughput - all verified under recommended operating conditions (1.8 V to 3.6 V supply).
Does the MSP430F5336IZQWR support crystal oscillators for both low- and high-frequency operation?
Yes, the MSP430F5336IZQWR supports dual crystal oscillators: XT1 accepts 32.768 kHz crystals for ACLK and RTC_B operation, while XT2 supports crystals up to 32 MHz for MCLK/SMCLK generation. Both are fully integrated with internal load capacitors and configurable startup timing per the device's oscillator specifications.
How many I/O pins does the MSP430F5336IZQWR provide, and are they all individually configurable?
The MSP430F5336IZQWR provides 74 general-purpose I/O pins across ports P1–P9, PJ, and PU.0/PU.1. Each pin is individually configurable for direction, pull-up/down, drive strength (full/reduced), interrupt edge sensitivity, and peripheral function multiplexing - confirmed in the functional block diagram and port register descriptions.
What is the role of the integrated LDO in the MSP430F5336IZQWR?
The integrated LDO in the MSP430F5336IZQWR generates a stable 3.3-V core supply (LDOO) from an input voltage range of 1.8 V to 3.6 V (LDOI), eliminating the need for an external regulator. It supports programmable core voltage scaling and includes built-in supervision for brownout detection and reset generation - critical for reliable low-voltage operation.
Can the MSP430F5336IZQWR operate from a single coin-cell battery?
Yes, the MSP430F5336IZQWR operates down to 1.8 V and draws only 1.8 µA in LPM3 mode (with RTC and crystal active), enabling direct operation from a single CR2032 coin cell (3 V nominal, ~2.0–3.0 V discharge curve) for multi-year runtime in low-duty-cycle applications such as remote sensors or meters.
