MSP430F5659IPZ vs MSP430F5659IPZ and IPZR

Kosta Logutin

Hi All, 

Because of shortage microcontrollers for MSP430F5359IZQWT BGA-113 we want to understand if it is possible to use  MSP430F5659IPZ and IPZR instead without changing layout of PCB.

All these microcontrollers showing under the same data sheet. 

From the datasheet it looks like it could be a close match with minimal or no layout changes. Please correct me if I'm wrong. 

It differs from the MSP430F5359IPZ because it has a USB (that can be disabled) and if disabled the 2K SRAM for the USB can be used for anything else. So, effectively it has the same 66KB SRAM as the part we are using.

Can you please advise if there are some big difference between them. 

 This is minimum requirements for our devices:

Core arch: CPUXV2

Freq:: 20MHz

Flash:512kB

SRAM: 66kB

PIO: 74

I2C: 3

ADC: 10 BIT

Thank you !!!

    Hi Kosta,

    You are correct that these devices are incredibly similar.  Both of the MSP430F5659IPZ and IPZR devices you listed have the exact same specs for the requirements you listed, and therefore satisfy these requirements.  However, if you used the MSP430F5359IZQWT BGA-113, you may need change the PCB, since the BGA-113 means that it is a ball grid array with 113 pins.  Meanwhile, the IPZ and IPZR devices have 100 pins.

    As a side note, the only difference between the IPZ and IPZR devices has to do with packaging. I've attached a screenshot from the datasheet that goes over general nomenclature.  The IPZ device uses a Jedec tray package, while the IPZR package uses a large tape and reel.

    Let me know if you have any further questions.

    Sincerely,

    Kyle Holub
