What are the key features of MSP430P325IPM?
- 16-bit MSP430 CPU core with ultra-low-power standby modes down to sub-µA supply current for multi-year battery life
- 16 KB one-time-programmable (OTP) Flash memory for secure, tamper-resistant code storage in field meters
- Integrated ADC for direct analog sensor digitization without external converter ICs
- 64-pin LQFP package with boundary-scan (JTAG) for in-system programming and production testing
What is MSP430P325IPM used for?
The MSP430P325IPM is purpose-built for smart metering, flow measurement, and portable medical devices where extremely low current consumption is critical for multi-year battery operation. Its 16-bit arithmetic core handles fixed-point meter calculations accurately at 3.3 MHz while waking from low-power mode in under 6 µs. The 64-pin LQFP package provides sufficient I/O lines for LCD segment drivers, communication interfaces, and analog sensor inputs in a single-chip meter solution.

Frequently Asked Questions
What type of program memory does the MSP430P325IPM use and why is it chosen for metering products?
The MSP430P325IPM uses 16 KB of OTP (one-time-programmable) memory rather than re-programmable Flash, which provides a cost advantage in high-volume meter production. OTP memory cannot be altered after programming, making it resistant to accidental code corruption or tampering in revenue-grade meters. The 16 KB capacity is sufficient for a complete metrology algorithm, calibration coefficients, and communication stack in a compact 64-pin LQFP package.
How does the MSP430P325IPM's low-power architecture extend battery life in portable instruments?
The MSP430 family achieves standby current in the range of 0.1 µA to 1 µA in its deepest sleep modes, allowing a small 3 V lithium coin cell to last over 10 years when the device wakes periodically to take a 12-bit ADC measurement. The MSP430P325IPM's ability to wake in under 6 µs means the duty cycle can be extremely low, minimizing active-mode consumption which typically runs at less than 1 mA at 3.3 MHz.
When should a designer select the MSP430P325IPM over a reprogrammable MSP430 variant for a meter application?
The MSP430P325IPM is the right choice when firmware is fully validated before production and the application requires 16 KB of code storage, since OTP variants cost less per unit than Flash-based MCUs at quantities above 10,000 pieces. If the design needs firmware updates in the field or multiple firmware versions during development, the MSP430F325 with 16 KB in-system-programmable Flash is a pin-compatible alternative. Both share the same 64-pin LQFP footprint, so PCB layout is identical.
