Description
The CoolRunner-II 64-macrocell device is designed for both
high performance and low power applications. This lends
power savings to high-end communication equipment and
high speed to battery operated devices. Due to the low
power stand-by and dynamic operation, overall system reli-
ability is improved
This device consists of four Function Blocks inter-con-
nected by a low power Advanced Interconnect Matrix (AIM).
The AIM feeds 40 true and complement inputs to each
Function Block. The Function Blocks consist of a 40 by 56
P-term PLA and 16 macrocells which contain numerous
configuration bits that allow for combinational or registered
modes of operation.
Additionally, these registers can be globally reset or preset
and configured as a D or T flip-flop or as a D latch. There
are also multiple clock signals, both global and local product
term types, configured on a per macrocell basis. Output
control signals include slew rate control, bus hold and open
drain. A Schmitt trigger input is available on a per input pin
basis. In addition to combinatorial and registered outputs,
the registers may be configured as fast inputs.
Clocking is available on a global or Function Block basis.
Three global clocks are available for all Function Blocks as
a synchronous clock source. These clocks are additionally
used to set or preset individual macrocell registers on
power up. Local clocks are generated in specific Function
Blocks and only available to macrocell registers in that
Function Block.
A DualEDGE flip-flop feature is also available on a per mac-
rocell basis. This feature allows performance where it is
needed without raising the total power consumption of the
entire device.
The CoolRunner-II 64-macrocell CPLD is I/O compatible
with standard LVTTL33 and LVCMOS18, 25, and 33 volts
(see Table 1). This device is also 1.5 volt I/O compatible
with the use of Schmitt inputs.
