Introduction
The SMT128 is a 3 site TIM carrier card with additional customised features, acting
as a supports environment for a DSP TIM and two other peripheral TIM’s. The
various ‘on-board’ peripherals available on the motherboard are listed below.
•
TIM Site 1: Standard Single width TIM site capable of accepting any TIM
compatible card. For the most embedded projects this can be a DSP processing
card. It has full COMM-PORT and Global Expansion Bus interconnectivity. The
site is also capable of accepting C6x based DSP although only four com-ports are
available. These com-ports are routed to the PL2 DIN connector for inter-module
communication via com-ports (0,1,3,4) via a buffer CPLD.
•
TIM Site 2: Standard Single Width TIM site with additional 26 way and 24 way
IDC sockets, see mechanical/electrical information. This is designed to accept
the SMT397 12 channel differential ADC/DAC TIM although other peripheral
TIM’s can be used.
•
TIM Site 3: Standard Single Width TIM site with two additional 24 way IDC
sockets, see mechanical/electrical information. This is designed to accept the
SMT392 4 channel RS422 Transceiver/Digital IO TIM although other peripheral
TIM’s can be used..

Motherboard Resources/Peripherals
•
Power Supplies 3.3V, 5V +-15v all generated.
•
Control FPGA
•
Digital Inputs/Outputs

Power Monitor & Watchdog
•
8K bytes of EEprom that can be used to store application parameters.
•
JTAG Port

4Mbit FLASH ram for application Software
•
Quad UART with links to the DIN connectors and also one to an RS232
connector.
The Motherboard has 2 DIN4162 connectors placed at the back of the board which
conform with the VME mechanical specifications. The Pin-out out the connectors is
given later in this specification. Four of the DSP com-ports are available on the back
panel connectors to allow multiple boards to communicate with each other. Each
com-port has a control circuitry to allow motherboard in a system to be ‘hot
swappable’.
