Noritake VFD SCK-3900-512X32H-01

Recommended Posts

I filled out the survey as soon as it came in really hoping for this display. I guess I missed it by || that much! Hope to see some great looking projects using these!

Eh, they didn't give me any notification before it just arrived so don't lose hope (unless you got an email about something else?)

Documenting the connectors on the back.

 

Looking at the back of the display:

+---+
|CN1|  I/O to onboard Hitachi H8 MCU (not sure if this is for user applications)
+---+

     +-----+------+--------+--------+--------+--------+------+
  13 |VCC1 | P1.1 |  P1.3  |  P0.1  |  P0.3  |  P0.5  |  P0.7| 1
     |(5V) |      |        |        |        |        |      |
     +-----|------|--------|--------|--------|--------|------+
     |     |      |        |        |        |        |      |
  14 |GND  | P1.0 |  P1.2  |  P0.0  |  P0.2  |  P0.4  |  P0.6| 2
     +-----+------+--------+--------+--------+--------+------+
 +---+
 |CN2|  RS-232 Command and Data Input to Display with DTR flow-control
 +---+

       +----+------+-----+-----+----+-------+----+
    1  |RXD |  DTR | DSR | TXD | NC |  VCC1 | GND| 7
       |    |      |     |     |    |  (5V) |    |
       +----+------+-----+-----+----+-------+----+

        RXD, DSR use RS232 voltage levels (Vlow = -3 to -15V, Vhigh = 3 to 15V)
        TXD, DTR use Vlow = -5V, Vhigh = 5V
 +---+
 |CN5|  8-bit Parallel Command and Data Input (HD44780-style)
 +---+  Uses 5V CMOS levels (Vhigh = 0.8*VCC1-to-VCC1)


       +-----+-----+-----+-----+-----+-----+-----+----+
   15  |VCC1 | GND | GND | GND | D1  | D3  | D5  | D7 |  1
       |(5V) |     |     |     |     |     |     |    |
       |     |     |     |     |     |     |     |    |
       +----------------------------------------------+
   16  |VCC1 | GND | RDY | /WR | D0  | D2  | D4  | D6 |  2
       |(5V) |     |     |     |     |     |     |    |
       +-----+-----+-----+-----+-----+-----+-----+----+
        RDY is an open-drain output pulled to VCC1 (5V) via 47K resistor.  /WR and Dx lines are inputs.
 +---+
 |CN6|  Power rails
 +---+

       +-----+-----+-------+----+--------+
    1  |VCC1 | GND | VCC2  |GND | TEST   |  5
       |(5V) |     | (24V) |    | (Debug)|
       +-----+-----+-------+----+--------+

       TEST should be left floating and is
       for debugging purposes.

       VCC1 = 4.75-5.25VDC with ~80-120mA draw
       VCC2 = 22.8-25.2VDC with ~270-350mA draw
              with more than 2X this current possible in
              the first 100ms upon power-on.

Thanks to @@Rickta59 for informing me of www.asciiflow.com !

What I've read, connector CN1 is for GPIO for the processor so it can toggle external devices and read inputs like switches; 8 bi-directional GPIO and 4 inputs. I believe VCC and GND are supplies for external circuits. You might get more information looking at the "macros" PDF and this product- "Message Selector Kit".

Yup that looks like what it's meant for. Nice! Particularly impressed at the price they ask lol...

 

And that H8 microcontroller onboard, I don't think it's much if any more powerful than an MSP430. Just gives some perspective on what can be done with a little MCU.

@@spirilis - I was more impressed by the price we paid for just the display, the price they asked for a sample ($118), and the price of the display on Mouser ($365).

If it's anything like the H8S/2398... it's 32 bit, if that means anything. ;)

Oh yeah I am quite impressed (& thankful) at the price we paid :D

 

Ok H8S is different. Superceded by the Renesas RX, it's more like the TI Tiva-C I bet.

edit: not even, it lives somewhere between the 2 architectures in capability. Also conflicting info on that page whether it's 32bit or 16bit.

Ah we had a big Lantronix serial-ethernet bridge at my last job early on (~10yr ago) to support some old Sun servers. Fascinating way to do it I guess. I never did get my display working but that's mostly out of laziness (was gonna rig up 2 UPS batteries for 24V)

Just curious if anybody who responded to the feedback survey received a Lantronix device?  Never heard anything back from Noritake on that.
