UIO 2010 Universal I/O Module

Product Description

The UIO 2010 is a 64 channel Universal I/O VMEbus module. The board contains five FPGAs which are interconnected to allow data routing from the VMEbus to the front panel connectors. One FPGA forms the VMEbus interface. The other four each route 16 I/Os to the front panel and have a 32-bit data bath to the VME data buffers. The master FPGA communicates with the slaves via 16 control lines (of which three are used for the buffered lemo inputs)

Specification

Power Requirements
+5V @ 350mA from the mandatory VME supply.

Front Panel Connectors

A &B - 68-way mini delta
Pins 1-31 (odd) I/Os 1-16
Pins 2-32 (even) Returns
Pins 37-67 (odd) I/Os 17-32
Pins 38-68 (even) Returns
Pins 33-36 Ground
SK1 - Lemo single pole
Schmitt TTL input with 1Kohm to +5V. Logic 0 true
SK2 -Lemo single pole
Schmitt TTL input with 1Kohm to +5V. Logic 0 true
SK3 - Lemo single pole
Schmitt TTL input with 1Kohm to +5V. Logic 0 true.

Architecture

The circuitry includes five Xilinx FPGAs: the first decodes and controls VME access, the other four each contain 16 I/Os.

Six jumpers set the base address of the unit and an additional two jumpers the FPGA number. Thus if the BA is set to 0xF000 and the FPGAs 0-3 ther addresses are 0xF000, 0xF100, 0xF200, 0xF300.

Each slave FPGA then has the following registers

00 ID Read Only D16
02 Model Type Read Only D16
04 CSR Write/Read D16
06 Data Register Write/Read D16 (for example)

ID

The ID registers contains the Hytec identifier.

Model Type

This register contains the model type number - 2010

Overflow Register

This register provides the overflow status of each scaler with bit 0 corresponding to scaler 0, bit 1 scaler 1 etc. The register can be cleared by writing a logic 1 to bit 8 of the CSR

CSR

0 Busy A logic 1 indicates module busy - the module is being used.
4 Ready. A logic 1 indicates that the module is ready.
8 Reads the state of SK1
9 Reads the state of SK2
10 Reads the state of SK3

Address Modifiers

AM29 (short non-privileged)

Operating Temperature Range

0 to +45 deg Celsius ambient.

Mechanical

6U single width VME module with access to P1 and P2 connectors.
