The AppleLogic ASIC Adaptor provides a mechanism to interface custom Application Specific Integrated Circuits in any DIP package up to 40 pins to the development platform. By using 5V bilateral logic level translators, both 5V and 3V ASICs can be interfaced to any particular FPGA. Using a standard constraint definition file, the ASIC can then be included in the FPGA project or design.
ASIC Adaptor Peripheral Board
The AppleLogic ASIC Adaptor board supports a selectable target VCC power supply of either 3.3V or 5.0V. Using the jumper select banks the ASIC can then have any of the 40 pins configured as either GND or VCC. The remaining jumper pins not used become IO, and may be connected to a logic analyser to monitor device activity during development if required.
The ASIC Adaptor supports the following features:
- Accepts TTL or CMOS ASIC's up to 40 Pins
- Accepts DIP packages of 8, 16, 20, 24, 28, 32 and 40 Pins
- Selectable VCC of either 3.3V (CMOS) or 5V (TTL)
- Any pin may be configured for either VCC, GND or IO
- High speed voltage translators on board and bi-directional
- 40 pin ZIF (Zero Insertion Force) socket
- Standard Nanoboard II peripheral board footprint
- LED indicators for all IO activity
- Logic Analyser interface
