Product details

16-bit MCU for low-power mixed-signal control

NRND — plan a last-time buy or second source

That means TI has stopped active design-in support, though the part remains available for existing production runs through the independent channel. For a BOM that already qualifies this MCU, the window to secure final lifetime volumes is open but narrowing. The MSP430F5xx family includes pin-compatible density variants — an engineer cross-referencing the base product number MSP430F5437 can evaluate a step up to a higher Flash/RAM sibling within the same 80-LQFP footprint, but that requires a firmware port and re-qualification.

The core runs at 18 MHz. The 16-channel 12-bit ADC conversion time is the throughput limit. 256 KB of Flash and 16 KB of RAM support a Modbus RTU slave with a lookup table and sensor buffer.

Sourcing posture

For a BOM line already using the MSP430F5437IPNR, an RFQ is the right next step to lock in allocation before the NRND window closes.

Frequently asked questions

Is MSP430F5437IPNR obsolete or NRND?

The MSP430F5437IPNR is NRND (Not Recommended for New Designs). It is not yet fully discontinued, but TI no longer recommends it for new projects. Existing production can continue via the independent channel for now.

What is the closest pin-compatible alternative to MSP430F5437IPNR?

No official successor is listed. Within the MSP430F5xx series, higher-density siblings in the same 80-LQFP package (such as those with 512 KB Flash) are pin-compatible but require firmware changes and re-qualification.

What is MSP430F5437IPNR's listed speed?

The core processor runs at 18 MHz, which is the maximum clock rate for the MSP430 CPUXV2 in this device.

Where can I buy MSP430F5437IPNR?

The MSP430F5437IPNR is sourced and quoted to order through independent distribution. Submit an RFQ for current availability and pricing — no stock or lead-time figures are published here.
