Product details
Overview
MSP430F5338IZCAR 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 battery backup, and 74 GPIO pins - deployed in portable sensor systems and battery-powered metering.
For engineers reviewing the MSP430F5338IZCAR datasheet, MSP430F5338IZCAR pinout, MSP430F5338IZCAR application, or MSP430F5338IZCAR equivalent, key selection criteria include active-mode current (270 µA/MHz @ 8 MHz), standby LPM3 current (1.8 µA @ 2.2 V), wake-up time (3 µs), 12-bit ADC linearity (±1 LSB INL), and nFBGA-113 package compatibility with high-density PCB layouts.
Technical Context
The MSP430F5338IZCAR 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; DAC12_A provides synchronized dual-channel voltage output; USCI_A0/A1 handle UART/IrDA/SPI; USCI_B0/B1 support I²C and SPI; Timer_A (TA0/TA1/TA2) and Timer_B (TB0) deliver PWM, capture/compare, and real-time counting with up to 7 CC registers.

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 |
|---|---|---|---|
| MSP430F5336IZCAR | 128 KB flash, same 18 KB RAM, identical peripherals and pinout; lacks second DAC channel. | Suitable for cost-sensitive designs where dual DACs are unnecessary; retains full ADC, RTC, and USCI functionality. | Select when firmware size ≤128 KB and dual DAC is not required - identical footprint and migration path. |
| MSP430F6638IZQW | 256 KB flash, 16 KB RAM, added USB PHY, different USCI register mapping; ZQW package (discontinued LTB status). | Required only if native USB device interface is needed; incompatible with existing MSP430F5338 firmware due to peripheral address changes. | Choose only for new USB-enabled designs; avoid for drop-in replacement - requires full hardware and firmware redesign. |
Compared with MSP430F5336IZCAR, the MSP430F5338IZCAR adds 128 KB flash and dual DACs at identical power and pinout; versus MSP430F6638IZQW, it trades USB for proven stability, broader toolchain support, and active production status - making it optimal for non-USB, high-precision analog-centric applications.

FAQ
What is the maximum system clock frequency supported by the MSP430F5338IZCAR?
The MSP430F5338IZCAR supports a maximum system clock (MCLK) frequency of 25 MHz, achieved using the FLL with XT2 crystal or external clock input up to 32 MHz. The device is characterized for reliable operation at 20 MHz across the full temperature and voltage range, with 25 MHz validated under specific conditions per TI specification SLAS721F Section 8.19.
Does the MSP430F5338IZCAR support crystal oscillators for both low- and high-frequency timing?
Yes, the MSP430F5338IZCAR integrates dual crystal oscillator circuits: XT1 accepts 32.768 kHz crystals for RTC and ACLK generation, while XT2 supports crystals up to 32 MHz for SMCLK and MCLK. Both support bypass mode for external clock injection, and oscillator fault detection is built into the PMM module.
How many analog input channels does the 12-bit ADC on the MSP430F5338IZCAR support?
The ADC12_A module in the MSP430F5338IZCAR supports 16 total input channels: 12 external analog inputs (A0–A11) and 4 internal sources (temperature sensor, VREF generator, supply voltage, and VMID). Channel selection is fully programmable via ADC12MCTLx registers with autoscan sequencing capability.
Is the MSP430F5338IZCAR pin-compatible with other devices in the MSP430F533x family?
Yes, the MSP430F5338IZCAR shares identical pinout and package dimensions with MSP430F5336IZCAR, MSP430F5335IZCAR, and MSP430F5333IZCAR in the nFBGA-113 (ZCA) package. Functional differences exist in flash/RAM size and DAC presence, but PCB layout and signal routing remain interchangeable across the ZCA variants.
What debug interface does the MSP430F5338IZCAR use, and how many pins are required?
The MSP430F5338IZCAR uses the 2-wire Spy-Bi-Wire (SBW) interface for programming and debugging, requiring only two pins: SBWTDIO (bidirectional data) and SBWTCK (clock). This replaces traditional 4-wire JTAG, reducing debug footprint and enabling in-system firmware updates without external voltage programming.
