Product details

The Texas Instruments MSP430F5338IZQWR is a 16-bit MSP430 CPUXV2 microcontroller clocked at 20 MHz, with 256 KB of Flash program memory and 18 KB of RAM. It packs 74 general-purpose I/O lines, a 16-channel 12-bit ADC, a dual 12-bit DAC, and serial connectivity spanning I2C, SPI, UART/USART, LIN, and IrDA — enough peripheral mix to handle sensor fusion, motor-control feedback loops, or industrial instrumentation without an external analog front-end. The 113-ball VFBGA (Microstar Junior, 7x7 mm) keeps the footprint compact, but the fine pitch means it belongs on a controlled-impedance PCB with solder-paste inspection capability, not a prototype board.

The 113-ball VFBGA package is moisture-sensitive — store the reels dry (MSL level per TI's label) and bake before reflow if the floor life has been exceeded.

Frequently asked questions

Is MSP430F5338IZQWR obsolete?

Yes, Texas Instruments lists the MSP430F5338IZQWR as Obsolete. No factory production or last-time-buy remains; supply is limited to surplus and broker inventory.

What is the replacement for MSP430F5338?

TI has not published a direct pin-compatible successor for the MSP430F5338. For new designs, consider the active MSP430F5xx or MSP430F6xx families — verify pinout and peripheral compatibility against your layout.

What is the supply voltage range for MSP430F5338?

The MSP430F5338IZQWR operates from 1.8 V to 3.6 V on the Vcc/Vdd rail.

Is MSP430F5338IZQWR compatible with MSP430F5438?

Both are 16-bit MSP430 CPUXV2 devices, but the MSP430F5438 uses a different package and peripheral set. Pin compatibility is not guaranteed — compare the datasheet pinouts before assuming a drop-in swap.
