Configuration Devices for ACEX, APEX, FLEX & Mercury Devices Data Sheet
Power &
Operation
This section describes Power-On Reset (POR) delay, error detection, and
3.3-V and 5.0-V operation of Altera configuration devices.
Power-On Reset
During initial power-up, a POR delay occurs to permit voltage levels to
stabilize. When configuring an ACEX 1K, APEX 20K, FLEX 10K,
FLEX 6000, or Mercury device with an EPC2, EPC1, or EPC1441 device,
the POR delay occurs inside the configuration device, and the POR delay
is a maximum of 100ms. When configuring a FLEX 8000 device with an
EPC1213, EPC1064, or EPC1064V device, the POR delay occurs inside the
FLEX 8000 device, and the POR delay is typically 100ms, with a
maximum of 200 ms.
Error Detection Circuitry
The EPC2, EPC1, and EPC1441 configuration devices have built-in error
detection circuitry for configuring ACEX 1K, APEX 20K, FLEX 10K,
FLEX 6000, and Mercury devices only.
Built-in error-detection circuitry uses the
nCS
pin of the configuration
device, which monitors the
CONF_DONE
pin on the ACEX 1K, APEX 20K,
FLEX 10K, FLEX 6000, or Mercury device. An error condition occurs if the
CONF_DONE
pin does not go high after all the configuration data has been
sent, or if the
CONF_DONE
pin goes high before the configuration device
has completed sending configuration data. When an error condition
occurs, the configuration device drives its
OE
pin low, which drives the
ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, or Mercury device
’
s
nSTATUS
pin low, indicating an error. After an error, configuration
automatically restarts if the
Auto-Restart Configuration on Frame Error
option is turned on in the
Global Project Device Options
dialog box
(Assign menu) in the MAX+PLUS II software. For APEX 20K and
Mercury devices, the Quartus software provides a similar option.
In addition, if the ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, or
Mercury device detects a cyclic redundancy code (CRC) error in the
received data, it may also flag the error by driving
nSTATUS
low. This low
signal on
nSTATUS
resets the configuration device, allowing
reconfiguration. CRC checking is performed when configuring all
ACEX 1K, APEX 20K, FLEX 10K, FLEX 6000, and Mercury devices.
