MSP430F5529 LQFP80 footprint Pitch? Minimal Circuit to Embed?


Recommended Posts

I am working on a school project that requires me to use the MSP430 microprocessor. While the entire class is working primarily with the MSP430G2553 launchpad, I have elected to use the MSP430F5529 launchpad as it uses a superior microprocessor in every respect. I have experience programming AVR chips and I could draw the minimum circuit for the ATMEGA1284p and ATMEGA328p blindfolded, I cannot seem to find a schematic of the minimal circuit for the MSP430F5529 on the web anywhere. Also I would like to point out that as an AVR guy, the documentation provided from Ti is pretty bad by comparison. 

 

Any information on these two topics would be helpful.

Pin pitch is 0.5mm.  F5529 package is called "PN".  All TI package designators can be looked up here- http://www.ti.com/sc/docs/psheets/mechanic.htm

Direct link to "PN" package diagrams: http://www.ti.com/lit/ml/mtqf010a/mtqf010a.pdf

 

The F5529 LaunchPad User's Guide has a schematic which may be helpful.  http://www.ti.com/lit/ug/slau533c/slau533c.pdf

 

Generally speaking with any TI MSP430 chip, there are a few rules of thumb-

 

1. 0.1uF ceramic capacitor between any DVcc and DVss or any AVcc and AVss.  You'll want something 4.7uF or so for the whole DVcc rail too.

2. RESET line usually needs a 47K pullup resistor and optionally, a <=2.2nF capacitor between RESET and GND.

3. TEST does not need any special treatment as it has an internal pulldown.

4. 32.768KHz tuning fork crystals may be used for the LFXT for precision RTC work; with F5xxx series MSP430's, there are no built-in load capacitors from what I recall, so you must supply those yourself.  MSP430G2xxx chips do have built-in software-selectable load capacitors.

5. High-frequency XTALs can be used and require that you provide the load capacitors.

 

There are other electrical guidelines found in the chip's datasheet.  It's been a long time since I've touched AVR so I don't recall how they do it.

 

Always go to the chip's TI product page for the docs - http://www.ti.com/product/msp430f5529 for user's manuals, application notes and the datasheet.  You'll see the available part IDs (with package identifiers at the end) somewhere in the product page too.
