Product details

USB-enabled 16-bit MCU for mixed-signal control

The 25 MHz clock rate is enough to run a USB stack with packet handling while leaving MIPS for sensor polling or a control loop. The USB peripheral (full-speed, not high-speed) integrates the PHY and transceiver, so no external USB chip is needed — that saves board area and BOM cost. The 32 KB Flash and 6 KB RAM are sized for a typical USB CDC or HID class implementation plus application code; if your firmware needs a larger heap or OTA staging area, you will want to budget the RAM against the 6 KB ceiling.

Package and layout: 48-VQFN with exposed pad

The 31 I/O pins are all 5 V tolerant, which simplifies level interfacing with older logic families.

For dual-sourcing, the MSP430F5508 is a pin-compatible sibling with 48 KB Flash — verify the memory map difference against your firmware image size before substituting.

Frequently asked questions

What is the difference between MSP430F5507IRGZR and MSP430F5506?

Both share the same 25 MHz CPUXV2 core, USB peripheral, and 48-VQFN package. The 5507 is the better fit if your firmware exceeds 16 KB.
