The purpose of this group is to foster exchange of information on the Texas Instruments MSP430 family of microcontrollers and related tools. Everyone welcome, all levels of familiarity/expertise.

Lead times - Rachel Adamec - Oct 31 9:04:04 2009

Hey all - been quiet, but have still been reading the list. I'm currently
working on a project using a 5438 and 2X series MSP430s.

Happy with parts, OK with tools (use IAR), but damn them lead times!

We're currently being quoted 20+ weeks "but that should get shorter in
1Q10." It seems like TI shut down fabs and sent everyone packing, and now
they're trying to hire everyone back and gear up again?!?

I was hoping that this was all because they decided to switch over to the
FRAM technology they talked about at the "We don't just make the MSP430"-day
last month. But even though that sounded really good and ready to roll out,
it seems like the issue is just poor (no?) planning.

My questions:

RE:lead times: WTF?

RE: New technology: Does anyone know when parts with the FRAM are supposed
to appear?

Did you see the reply from Scott (Roller) at Ti. Details below. An open
invitation to pass on your wish list, wants and needs.

I agree, for real low power FRAM is the only way to go for memory, flash
is too current hungry, especially if you want to use it as data memory
for logging.

"Ultra-low power is what has made MSP430 great over the years, and rest
assured, TI is hard at work right now on a number of advances with
MSP430 that will allow you to operate at power levels never thought
possible. It's a bit early to talk about them in a public forum like
this, but stay tuned for more details.

As an aside, I do take time to browse the posts to this forum each week.
It's a great resource for engineers designing with the MSP430 and it's
also gives me a window directly into the challenges you're running into
when designing with MSP430. I've been paying close attention to this
string in particular over the last couple of days, and while I typically
don't like to intrude, I felt compelled to respond to this one. I hope
you understand.

If you have some thoughts on how to make MSP430 better from an ultra-low
power perspective, I'd love to hear about them. You can email me
directly at s...@ti.com or call my offfice at +1.214.212.0288."

Use the timer in "up" mode to generate a PWM output (TBR0, TBR1). Use the timer interrupt to detect each time the timer (TBR0) rolls over. In the interrupt routine, count the number of roll-overs, and if you get to the number which adds-up to 2 ms, turn the output of the timer off, but keep it running. After the next 2 ms worth of counting roll-overs, turn the output back on.

Re: Lead times - old_cow_yellow - Nov 1 10:29:55 2009

Is this a challenge for TI to trim lead time from 20 weeks to 2 msec?

I know, you meant to reply to "Pulse bursts". Yes, that is one way of doing it. One could use another timer to do the 2ms on/off,
