Product details

OTP memory: no field updates possible

The 16 KB program memory is OTP — one-time programmable. That means the firmware is locked at the factory or during initial programming; there is no field-reprogramming path. This part suits designs where the firmware is finalised before production and no update cycle is planned. If your BOM requires in-system firmware updates, an OTP part cannot fill that line.

Industrial temperature range and deployment

Rated -40 to 85 °C, the device is specified for factory automation, outdoor telecom cabinets, and engine-bay-adjacent electronics where condensation and thermal cycling are expected. The 56-SSOP package is surface-mount, suitable for automated assembly on standard FR4 boards.

Frequently asked questions

What is MSP430P315IDL's core speed?

The MSP430P315IDL runs at 8 MHz.

Can MSP430P315IDL be reprogrammed in the field?

No. The program memory is OTP (one-time programmable), so firmware cannot be updated after initial programming.
