Description
The CoolRunner™-II 256-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 sixteen 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 pin
configurations include slew rate limit, bus hold, pull-up,
open drain and programmable grounds. A Schmitt-trigger
input is available on a per input pin basis. In addition to stor-
ing macrocell output states, the macrocell registers may be
configured as "direct input" registers to store signals directly
from input pins.
Clocking is available on a global or Function Block basis.
Three global clocks are available for all Function Blocks as
a synchronous clock source. Macrocell registers can be
individually configured to power up to the zero or one state.
A global set/reset control line is also available to asynchro-
nously set or reset selected registers during operation.
Additional local clock, synchronous clock-enable, asynchro-
nous set/reset and output enable signals can be formed
using product terms on a per-macrocell or per-Function
Block basis.
A DualEDGE flip-flop feature is also available on a per mac-
rocell basis. This feature allows high performance synchro-
nous operation based on lower frequency clocking to help
reduce the total power consumption of the device.
Circuitry has also been included to divide one externally
supplied global clock (GCK2) by eight different selections.
This yields divide by even and odd clock frequencies.
The use of the clock divide (division by 2) and DualEDGE
flip-flop gives the resultant CoolCLOCK feature.
DataGATE is a method to selectively disable inputs of the
CPLD that are not of interest during certain points in time.
