Miniature Card (Technical)

This section is currently based soly on the Miniature Card specification v1.1.

Signal Descriptions:

A0-A24

Address A0 to A24 are the address bus lines that can address up to 32 Mwords (64 MBytes). The Miniature Card specification does not require the Miniature Card to decode the upper address lines. A 2 Mbyte Miniature Card that does not decode the upper address lines would repeat its address space every 2 Mbytes. Address 0h would access the same physical location as 200000h, 400000h, 600000h, etc.

D0-D15

Data lines D0 through D15 constitute the data bus. The data bus is composed of two bytes, the low byte D[7:0] and the high byte D[15:8].

OE#

OE# indicates that the current bus cycle is a read cycle.

WE#

WE# indicates that the current bus cycle is a write cycle.

VS1#

Voltage Sense 1 signal. The card grounds this signal to indicate it can operate at 3.3 Volts. This signal must either be connected to card GND or left open.

VS2#

Voltage Sense 2 signal. The card grounds this signal to indicate it can operate at x.x Volts (the value to be determined at a later date). This signal must either be connected to card GND or left open.

CEL#

CEL# enables the low byte of the data bus (D[7:0]) on the card. This signal is not used in DRAM cards.

CEH#

CEH# enables the high byte of the data bus (D[15:8]) on the card. This signal is not used in DRAM cards.

RAS#

RAS# strobes in the row address for DRAM cards.

CASL#

CASL# strobes in the low byte column address for DRAM cards.

CASH#

CASH# strobes in the high byte column address for DRAM cards.

RESET#

RESET# controls card initialization. When RESET# transitions from a low state to a high state, the Miniature Card must reset to a predetermined state.

BUSY#

BUSY# is a signal generated by the card to indicate the status of operations within the Miniature Card. When BUSY# is high, the Miniature Card is ready to accept the next command from the host. When BUSY# is low, the Miniature Card is busy and unable to accept some data operations from the host. For example, in Flash Miniature Cards the BUSY# signal is tied to the components RY/BY# signal. However, ROM Miniature Cards would always drive BUSY# high since the host will always be able to read from a ROM Miniature Card.

Vccr

Vccr provides a low current (refresh) voltage supply. Vccr is a feature used by DRAM Miniature Cards to "self-refresh" during "sleep" mode.

SDA

I2C: Serial Data/Address.

SCL

I2C: Serial Clock are used to read the attribute information structure (AIS) from the serial EEPROM in a DRAM card.

CD#

CD# is a grounded interface signal. After a Miniature Card has been inserted, CD# will be forced low. The card detect signal is located in the center of the second row of interface signals, and should be one of the last interface signals to connect to the host. Do not confuse CD# with CINS#. CINS# is an early card detect that is one of the first signals to connect to the host.

BS8#

BS8# is a signal driven by the host to indicate if the data bus is x8 or x16. An 8-bit host must drive BS8# low and tie the high byte data bus D[15:8] to the low byte data bus D[7:0]. A 16-bit host must drive this signal high.

GND

Ground

Vcc

Vcc is used to supply power to the card.

CINS#

CINS# is a grounded signal on the front of the Miniature Card that can be used for early detection of a card insertion. CINS# makes contact on the host when the front of the card is inserted into the socket, before the interface signals connect.

shielding-----------------------------------------| |-shielding

connect the shielding of all cables to each other - but only
connect it to only ONE interface port connector (i used the
keyboard plug).

For the condensers C1..C5 you must get 1 uF electrolyt-condesers.
If your signal-converter is kind of the xxx232A (A-type) you must
use 0.1 uF instead (for C1..C5)       [source : Maxim Data Book]

Be careful with your explorations. I suggest the serial signals
are passed through directly to the PAULA chip - so they are
slightly sensitive.

Hi Stan !
 s> I understand that you can use the auxiliary port (keyboard) as an
 s> RS-232 port and that this is what sernet does.  But when I look at
 s> the pinout, there is only clock and data signals, not ser-in and
 s> ser_out.  What am I missing here?
Well, I think you refer to the A4000"s kb.jack pinout. It"s "almost"
the same as you can find at the cd32. But the difference is, tataa..:
on the cd32 there are additional serial-interface-signals connected
to the AUX-jack. You can find them at the former unused pins.
The mess is, that the (serial-) signals carry [negated] TTL-level.
As a result, you have to make sure that there is a level-conversion
before you connect them to other computers. Without you surely kill
your cd32.
The cd32-FAQ shows a rather complex (but quite correct) way to do this.
(Aehm, the level-conv., of course ;-)
If you plan to connect the CD32 with other Amigas then I found out a
rather easyer/cheaper way to solve that:

the pros. and cons.  ([1]this solution ./. [2]max232-sol. (->FAQ) )

pros.[1]:  easy to solder
           cheap
           fits within a SUB-D 25 plug
           does not consume CD32 +5V power ;-)

cons: "dirty" solution; i.e. circuitry makes use of the 1488/89 tolerances
      you may only connect Amiga-computers to your cd32 when using THIS
      [1] circuitry - since they all use the 1488/89 chip set.
      PCs "may" work, too. But interface board must contain 1488/89 chip
      set.
      I do believe that this will work on all Amigas -I tested it at least
      on 3 different Amiga-models, however, there is still no guarantee
      that this will work on yours.

However, I use both interface-types since about 6 months.  There has
been no problem yet.

 s> Also, has anyone made their own connector to the expansion port to
 s> pull off the RGB signals?  I"d appreciate hearing of your experience.

Yea, does work fine.  In use for about 6 months; and still no probs, too.
For details refer to the cd32-faq.

I am not quite sure about the cd32-pin numbers, just take a look in the
faq.

The RS232-TxD-signal carries +12V or -12V level. As the first step
in conversion the diode D1 blocks if the signal drops to -12V.
In this case the voltage divider (R1,R2) is only connected with
GND potential. So the gate input carries GND level, too.
When the RS232-TxD-signal changes to +12V the diode will pass it
through and the voltage divider now provides a +5V-level signal to
the gate input.
The backward conversion consists of simple negation of the cd32"s
/TxD signal. In fact there is no level conversion.
While the conversion for the received signal does
work proper with any RS232 opponent, the sended
signal furthermore carries TTL-level.
The opponent hardware tries to regain the TTL-level signal from
its "RS232" input. The conversion unit handles the provided
pseudo RS232-type signals correct (as we want ist to be:-).
(*) voltage divider R1-R2:

   U                      U      = 12V    U   = 5V
    R1+R2     R1+R2        R1+R2           R2
   ------  =  -----
   U            R2
    R2

                               U
                                R1+R2
   I      = 5 mA  ==> R1+R2 = ------   = 2400 Ohm
    R1+R2                      I
                                R1+R2

                     (R1+R2) * U
                                R2
   U   = 5V ==> R2 = -------------  = 1000 Ohm; R1= 1400 Ohm
    R2                  U
                         R1+R2

R1=1500 Ohm
R2=1000 Ohm ==> I=4.8 mA ==> U(R2)=4.8 V   ..  will be OK

IC1 = 74LS00  (4 NAND gates)
D1 = e.g. 1N4001
have fun !
be careful; I am in no way responsible for any damage that may result.

Есть ли справедливость в жизни?
Конечно есть, уверен!
Вроде как должна быть, но...
Затрудняюсь ответить...
Какая справедливость? О чем Вы?
Эх.., нет правды на свете!
