Product details
Overview
MSP430F5338IZQWR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with integrated 3.3-V LDO, 256 KB flash, 18 KB RAM, 74 GPIO, dual 12-bit DACs, 12-bit ADC (16-channel), two USCI modules (UART/IrDA/SPI/I²C), four 16-bit timers, RTC with battery backup, and hardware multiplier - deployed in portable sensor systems and battery-powered thermostats.
For engineers reviewing the MSP430F5338IZQWR datasheet, MSP430F5338IZQWR pinout, MSP430F5338IZQWR application, or MSP430F5338IZQWR equivalent, key selection criteria include LPM3 standby current (1.8 µA at 2.2 V), wake-up time (3 µs), 12-bit ADC sampling rate (200 ksps), MicroStar Junior™ BGA-113 package compatibility, and integrated LDO regulation for single-supply operation.
Technical Context
The MSP430F5338IZQWR implements a unified clock system with FLL stabilization, dual crystal support (XT1 up to 32 kHz, XT2 up to 32 MHz), and three internal sources (VLO, REFO, DCO). Its power management includes programmable core voltage via integrated LDO, brownout reset, supply voltage supervision, and five low-power modes (LPM0–LPM4.5).
Peripherals are memory-mapped and synchronized via 6-channel DMA; the ADC12_A module supports autoscan across 12 external + 4 internal channels with shared reference; DAC12_A provides synchronized dual 12-bit voltage outputs; USCI_A0/A1 support enhanced UART with auto-baud detection and IrDA, while USCI_B0/B1 support I²C and SPI.
Key Specifications
