MSP430FR2311IPW16R Low-Power 16-bit FRAM Microcontroller, 16-Pin Package

MSP430FR2311IPW16R Overview

The MSP430FR2311IPW16R is a low?power, 16?bit microcontroller built around the MSP430 family architecture. It pairs nonvolatile FRAM memory with a compact 16?pin package to deliver flexible embedded control in small form factors. The device targets battery?sensitive and cost?constrained designs that require more write endurance and faster writes than traditional flash. Designers benefit from lower active and standby currents versus many 8?bit alternatives and from tight integration of CPU, I/O, and analog peripherals.

FAQ

What package does this part use?

The device is offered in a 16?pin VSSOP package (designation PW). The full ordering code ends with IPW16R indicating the 16?pin PW package and reel packaging for volume assembly.

What memory type does it include?

It uses FRAM (ferroelectric RAM) for nonvolatile program and data storage. FRAM provides higher write endurance and faster write times than flash, favorable for frequent updates.

What voltage range does it support?

Operating voltage is 1.8 V to 3.6 V, which suits single?cell lithium and standard 3.3 V systems while allowing operation at lower supply rails for power?sensitive designs.

Is it suitable for industrial temperatures?

Yes. The device supports an ambient range from ?40 ??C to +85 ??C, making it suitable for many industrial and outdoor installations that require extended temperature operation.

Which peripherals are integrated?

Key on?chip peripherals include a 12?bit ADC and general?purpose I/O lines, which reduce external component count for sensor interfaces and simple control tasks.
