Product details

16-bit MSP430 with USB — what the 20 MHz ceiling and 128 KB Flash buy you

The MSP430F5636IPZ: The on-chip USB 2.0 full-speed interface (with UART, I2C, SPI, and IrDA alongside) makes this a natural fit for data-logging gateways, portable medical instruments, and industrial sensor hubs that need to talk to a host PC or a PLC over a serial link.

The 100-pin LQFP (14x14 mm) is a standard QFP footprint that reflows easily and can be hand-soldered for rework or low-volume prototypes — no BGA reflow profile needed.

That makes it a safe choice for a new design that will run for several years. For dual-sourcing or a drop-in upgrade path, a pin-compatible part with more Flash and RAM is available — the board layout and firmware port are minimal.

Frequently asked questions

Can MSP430F5636IPZ be replaced with MSP430F5637IPZ?

Yes, the MSP430F5637IPZ is a pin-compatible drop-in with more Flash and RAM. The package, core, peripherals, and pinout are identical, so the board layout does not change and the firmware port is straightforward.

What is the 20 MHz speed grade good for on this part?

The 20 MHz core clock is the maximum rated speed for the MSP430 CPUXV2 on this device. It sets the throughput ceiling for real-time control loops and data processing — enough for most sensor-fusion and USB-packet handling tasks, but not for high-rate DSP or video. The flash wait state must be configured correctly when running above 8 MHz to avoid bus faults.
