Configuration Devices for ACEX, APEX, FLEX & Mercury Devices Data Sheet
ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000 & Mercury Device
Configuration with Multiple EPC2 or EPC1 Configuration Devices
When configuration data for ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000,
or Mercury devices exceeds the capacity of a single EPC2 or EPC1 device,
multiple EPC2 or EPC1 devices can be cascaded together. (The EPC1441
device does not support data cascading.) If multiple EPC2 or EPC1
devices are required, the
nCASC
and
nCS
pins provide handshaking
between the devices.
When configuring ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, or
Mercury devices with cascaded EPC2 or EPC1 devices, the position of the
EPC2 or EPC1 device in the chain determines its operation. When the first
or master device in a configuration device chain is powered-up or reset
and the
nCS
pin is driven low, the master device controls configuration.
The master device supplies all clock pulses to one or more ACEX, APEX,
FLEX, or Mercury devices and to any subsequent slave devices during
configuration. The master EPC2 or EPC1 device also provides the first
stream of data to the ACEX, APEX, FLEX, or Mercury devices during
multi-device configuration. After the master EPC2 or EPC1 device
finishes sending configuration data, the master EPC2 or EPC1 device
drives its
nCASC
pin low, which drives the
nCS
pin of the first slave EPC2
or EPC1 device low. This action causes the slave EPC2 or EPC1 device to
send configuration data to the ACEX, APEX, FLEX, or Mercury devices.
The master EPC2 or EPC1 device clocks all subsequent slave devices until
configuration is complete. Once all configuration data is transferred and
the
nCS
pin on the master EPC2 or EPC1 device is driven high by the
ACEX, APEX, FLEX, or Mercury device
’
s
CONF_DONE
pin, the master
EPC2 or EPC1 device clocks 16 additional cycles to initialize the ACEX,
APEX, FLEX, or Mercury device(s). The master EPC2 or EPC1 device then
goes into zero-power (idle) state. If
nCS
on the master EPC2 or EPC1
device is driven high before all configuration data is transferred, or if
nCS
is not driven high after all configuration data is transferred, the master
EPC2 or EPC1 device drives the ACEX, APEX, FLEX, or Mercury device

Figure5
shows an ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, or
Mercury device configured with two EPC2 or EPC1 devices. Additional
EPC2 or EPC1 devices can be added by connecting
nCASC
to
nCS
of the
subsequent slave EPC2 or EPC1 device in the chain and connecting
DCLK

DATA
, and
OE
in parallel.
