Tews TIP620
Industry Pack	PowerPC	v. 4.0
Digital I/O

Tews' TIP620 is an IndustryPack®-compatible module emulating two Motorola MC68230 Programmable Interface/Timer (PI/T) ICs (without DMA). Together with the IDROM and additional logic they are integrated in a Xilinx Spartan II FPGA.

The TIP620-10 and TIP620-11 each has its own IDROM and I/O configuration. By changing solder connections, users may convert from one product to the other or intermediate configurations.

TIP620-10 is configured for 48 general purpose lines of bit I/O. Timer I/O is available. In this configuration 48 of the 50 cable lines are I/O, with 2 ground lines.

The TIP620-11 is configured to support additional features of the PI/Ts, such as timer, I/O, interrupts, and double-buffered data transfer with hardware handshake. 32 lines for bit I/O are available, 8-bit or 16-bit (unidirectional, bi-directional, single or double buffered) plus 8 lines as programmable handshake lines or timer I/O with alternate ground wires.
