The SBS Greenspring's IP-DIGITAL48 and IP-DUALPIT2 are two IndustryPack® compatible modules constructed from the same printed circuit board. Each has its own IDROM and factory configuration. However, by changing solder connections, you may convert from one product to the other, or to one of many intermediate configurations. The IP-DIGITAL48 and the IP-DUALPIT2 are drop-in replacements for the IP-Digital-48 and the IP-Dual-PIT. The IP-DIGITAL48 and IP-DUALPIT2 emulate 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 FPGA is configured at power up from a serial configuration PROM which is mounted in a socket. The IP-DUALPIT2 is configured to take advantage of the more sophisticated features of the PI/Ts. Timer, I/O, interrupts, and hardware mediated double-buffered data transfer are supported. 32 general purpose digital I/O lines are available in several programmable modes. The IP-DIGITAL48 is configured to maximize the number of digital I/O lines. Multiple modes are available via programming.

Users may reconfigure either IndustryPack to implement desired features, while maximizing the number of available I/O lines. Each MC68230 provides up to three 8-bit I/O ports, one 24-bit timer and five separate interrupt vectors. Ports may be software configured for bit I/O, unidirectional 8-bit and 16-bit I/O, or bi-directional 8-bit and 16-bit
I/O. Port modes include single and double buffering, with strobe and handshake options. Due to pin limitations, not all options are available simultaneously. The IP-DIGITAL48 and IP-DUALPIT2, like all IndustryPacks, use a 50-pin flat ribbon cable connected to the
carrier board for I/O. The IP-DUALPIT2 configuration uses 32 lines for bit I/O, 8-bit or 16-bit (unidirectional, bidirectional, single or double buffered) plus eight lines as programmable handshake lines or timer I/O with alternate ground wires.
IP-DIGITAL48 is configured for 48 general purpose lines of bit I/O. These lines may also be used for 8-bit and 16-bit I/O with handshake lines. Timer I/O is also available. In this configuration 48 of the 50 cable lines are I/O, with two ground lines. In this configuration, user provided cabling with additional grounds may be required for high speed operation. Interrupts are unavailable if all 48 lines are used for I/O. IP-DIGITAL48 and IP-DUALPIT2 connect user I/O lines to the Spartan2 inputs and outputs via 47 ohm serial resistors. They are TTL compatible (output voltage 3.3V, 5V tolerant). Source and sink current is 2mA and leakage current is 10 µA. Each of the two MC68230s has a 24-bit programmable timer. Timer clock source is a 250 KHz internal clock or a user provided external clock. Using the internal clock, a resolution of 4 µs with a maximum time of 64 seconds
is available. The timer may be used as a counter, watchdog, or square wave generator. It may generate single or periodic interrupts. An external gate signal as well as an external timer output is available. In general, it is easier to use the timers starting from an IP-DIGITAL48 configuration than from an IP-DUALPIT2 configuration. All communication between the IndustryPack and the carrier board is performed byte-wide.
