Product details

20 MHz 16-bit MCU with USB and mixed-signal peripherals

Internal oscillator keeps the clock tree self-contained for many applications.

No factory orders or last-time-buy windows remain open. There is no official TI successor listed for this specific variant, so a redesign to a current MSP430 or a different family is the long-term fix.

Package and footprint — 113-BGA Microstar Junior

The 74 I/O lines give ample room for parallel buses, keypad matrices, and sensor arrays without a port expander.

What the 20 MHz and 128 KB Flash mean for the design

The 128 KB Flash is sized for applications that need a USB stack, a modest RTOS, and application code, but it will fill quickly if you add a GUI library or extensive lookup tables. Plan the memory budget early.

Frequently asked questions

Is MSP430F5636IZQWT obsolete?

Yes, Texas Instruments lists the MSP430F5636IZQWT as Obsolete. No factory orders are accepted. The only supply channel is surplus inventory from independent distributors.

Can MSP430F5636IZQWT be cross-referenced to MSP430F5636IPZ?

The MSP430F5636IPZ uses the same core and memory but comes in a 100-pin LQFP package, not the 113-BGA Microstar Junior. They are not pin-compatible — the BGA and LQFP footprints differ completely. A board redesign is required to swap between them.

What is MSP430F5636IZQWT's listed speed?

The CPUXV2 core runs at 20 MHz, delivering approximately 20 MIPS for the 16-bit instruction set.
