PMS430E325AFZ

Microcontrollers Overview

The PMS430E325AFZ is an EPROM version of the MSP430P325A mixed-signal microcontroller, housed in a 68-pin JLCC package. It features a 16-bit RISC CPU with 16 kB OTP/EPROM memory and 512 bytes of RAM. The device operates within a supply voltage range of 2.5 V to 5.5 V and supports a system clock up to 3.3 MHz via an internal FLL. Key peripherals include a 12+2 bit ADC with six multiplexed inputs, an integrated LCD driver for up to 84 segments, and multiple timer modules.

Microcontrollers Feature Summary

• Ultra-low power architecture supporting five power-saving modes with standby current down to 0.1 µA
• Integrated LCD driver capable of handling up to 84 segments with configurable mux rates
• Built-in 12+2 bit analog-to-digital converter with software-controlled range selection
• Frequency-locked loop (FLL) enables rapid wakeup from low-power modes in under 6 µs

Microcontrollers Applications

• Sensor systems requiring analog signal capture and digital processing
• Battery-operated devices demanding extended operational lifetime
• Prototyping environments utilizing EPROM versions for code modification
• Applications necessitating direct LCD display integration

Microcontrollers Procurement Notes

Verify that the specific ordering suffix corresponds to the 68-pin JLCC ceramic package and the 25°C operating temperature range. Confirm the component is the EPROM variant intended for prototyping rather than the OTP or ROM production versions. Ensure compatibility with existing 68-pin footprints and programming interfaces.

Microcontrollers Selection Notes

Select this component when EPROM reprogrammability is required for development cycles. The 68-pin JLCC package offers robustness for specific industrial environments compared to plastic packages. Consider the 2.5 V to 5.5 V supply range for flexibility in power design. Evaluate the 3.3 MHz maximum clock speed against application timing requirements.

Microcontrollers Part Context

This part belongs to the MSP430x32x family of ultra-low-power mixed-signal microcontrollers. It shares the core architecture with the MSP430C325 and MSP430P325A but utilizes EPROM technology. This allows for field reprogramming, distinguishing it from the one-time programmable OTP and mask ROM variants within the same series.
