Cardstac is a modular
circuit specification that you are free to use with your own projects. Cardstac
is a specification for small, stack-able test and evaluation
modules. These modules can be connected (stacked) as “building
blocks” to form electronic systems with processing and IO
capability. Cardstac
modules are primarily intended for electrical educators, students, and
designers as a vehicle for quickly testing and prototyping electronic
devices and circuits. Manufacturers can also utilize the modules to reduce design and debug effort for
short lead-time products, or to provide flexibility in product
implementation.
Cardstac modules can be used for:
|
|
Evaluation of IC devices
and new circuits. |
|
|
Testing of digital IP
(intellectual property) and ASIC prototyping. |
|
|
Design cycle reduction
(through replication of module design and documentation into new
designs). |
|
|
Short lead-time products. |
Cardstac Summary Information:
Card Size: A credit card provides
ample space for a minimal design, and most of us have a handy size
reference in our pocket. Half size cards (60 pin) are also defined.
Pin Inter-connect: Simple 0.1 inch
pitch pin headers are utilized in 256, 128, and 60 pin counts.
Provide common digital interfaces in standardized pin locations. Pin
mapping symmetry and “pass thru” pin headers allow for module stacking
and rotation. Carrier cards can also be utilized to provide pin
inter-connect.
Card Power:
3.3V and two auxiliary power rails (VAUX0_+5V and VAUX1_+12V) are
provided . A stack of cards is limited to 2 Amperes per power
rail (if applied using the pin headers only).
