LM49350: I2C auto increment?

Michael Snyder

Part Number: LM49350
Other Parts Discussed in Thread: LP5030,

Hi. I'm using a few TI chips in a design.

One of them, the LP5030, has auto increment on i2c, so I can start at register address 0x00, and each subsequent byte is stored in the correctly incremented register address.

Does the LM49350 also do this auto increment? 

It would be nice to transmit a single buffer for configuration of all registers. 

Also, why is the LM49350 eval obsolete? 

Are there any modules available? 

Thanks!

    Michael, 

    I believe the LM49350 does do auto increment.  unfortunately I do not have an LM49350 EVAL board to test this out on. I could test it on an LM49352 which should be very similar. 

    The reason the EVAL board is obsolete is due to ICs on the Motherboard being obsoleted. At that time there was some discussion about moving the eval boards to a new mother board platform,  but due to the efforts of updating the hardware and software, the decision at that time was to discontinue the eval platform. we have seen some renewed interest in the LM4935x family and if this trend continues, I imagine this decision could be revisited. 

    I do have a LM49352 Eval board that I can send you if you like, It is similar to the LM49350, with improved performance and minor changes to the analog inputs. The control software only works on windows XP.  So you would either need to use your own processor to program the EVM or find an old PC.  Due to the software age and lack of computers that use windows XP,  We would be unable to support the software from our end.

    best regards,

    Thanks for all the info Steve! This was very helpful. 

    I would definitely be interested in trying the LM49352 Eval board. 

    I can probably use my MCU or an aardvark to configure it.
