MSP430F4491: List of compatible devices

Part Number: MSP430F4491

Hi Team, 

A customer is looking for a pin-to-pin direct replacement for MSP430F4491IPZR (package is LQFP100) that costs less. 

These are the important specifications he need for the replacement.

60K storage for the firmware, ADC, two timers, and the 160 segment LCD interface.

Do we have a list of direct replacement for MSP430F4491IPZR? 

Regards,

Danilo

  • Hi Danilo,

    While we don't have a list of pin-to-pin compatible devices (outside of the F43/44xx family), you can leverage our product tree filters to find a device that meets your requirements. I gave it a shot by selecting LQFP, LCD, >60KB non-volatile memory, so you should be able to narrow down your selection using the link below.

    It may be a good time to consider one of our FRAM devices. Also, can you share the application or end equipment?

    Hi James,

    Thank you for sharing the list. The application is for swimming exercise device to measure power. The customer needs an MSP430 MCU with 160 segments. Our list of devices doesn't show the number of segments that each device can drive. Do we have a table or list showing the number of LCD segments in the MCU?

    Thank you for sharing the list. The application is for swimming exercise device to measure power. The customer needs an MSP430 MCU with 160 segments.

    You'll need a device with LCD_A module or later. Please see Table 1 in the Designing With MSP430™ MCUs and Segment LCDs app note. Since MSP430F4491 features the first LCD module, most of the devices you see in the shared list should support 160 segments or more.
