Page 16: Xilinx Spartan Series High Performance, Low Cost FPGAs with on-chip SelectRAM Memory.

Spartan-XL Interconnect

Carry only propagates upward Significantly higher speed

– Similar to XC4000X Standard long line can be used to continue at the

bottom of the next column

Datasheet figure shows upward carry only Text describes that it is bidirectional in the 5V Spartan

family

All other device routing is identical to 5V Spartan family

Optional 3.3V Clamp for PCI

Programmable global clamp to 3.3V for PCI No VTT pins required BITGEN option

– Default is “5V Tolerant I/Os” Similar to XC4000XLA

Page 19: Xilinx Spartan Series High Performance, Low Cost FPGAs with on-chip SelectRAM Memory.

Spartan-XL Output Drive

Programmable 12 mA or 24 mA output drive Pin-by-pin option Default is 12 mA Similar to XC4000XLA

Page 20: Xilinx Spartan Series High Performance, Low Cost FPGAs with on-chip SelectRAM Memory.

Spartan-XL Boundary Scan

M2 pin taken out of scan chain BSDL files are different than 5V Spartan

Added IDCODE Instruction Becomes default instruction

Simplified configuration via boundary scan No need to hold INIT Can abort and retry

Similar to XC4000XLA

Page 21: Xilinx Spartan Series High Performance, Low Cost FPGAs with on-chip SelectRAM Memory.

Spartan-XL Power Down

Former M2 pin has a power-down function Active-low with default pull-up

Disables I/O and OSC, asserts GSR Can be asserted before configuration

After power down is removed, GSR and input disable are removed before outputs are enabled

Cannot lower VCC during power-down

Power down current not yet characterized

Page 22: Xilinx Spartan Series High Performance, Low Cost FPGAs with on-chip SelectRAM Memory.

Spartan-XL Factory Test Input

Former M1 pin is still a “Don’t Connect”

Enables Express Mode configuration for factory testing

Default pull-up prevents Express mode

FPGA Challenge (FireWire Example)

FireWire part of PC99 spec is used to demonstrate the benefits of Xilinx FPGAs

IEEE 1394 standard based on Apple’s original definition of FireWire

High speed serial bus 400 Mbits/s required for PC99; increasing to 3.2 Gbits/s

For emerging consumer electronics digital camcorders, DVD players, digital VCRs, HDTV,

set-top boxes, video conferencing

For traditional PC peripherals hard drives, printers, scanners, modems
