Note
(1) 240-pin QFP packages do not support the MultiVolt I/O features, so they do not have separate V
pins.
CCIO
Power Sequencing & Hot-Socketing
Because FLEX 10K devices can be used in a multi-voltage environment,
they have been designed specifically to tolerate any possible power-up
sequence. The VCCIO and VCCINT power supplies can be powered in any
order.
Signals can be driven into FLEX 10KA devices before and during power
up without damaging the device. Additionally, FLEX 10KA devices do
not drive out during power up. Once operating conditions are reached,
FLEX 10KA devices operate as specified by the user.
All FLEX 10K devices provide JTAG BST circuitry that complies with the
IEEE Std. 1149.1-1990 specification. All FLEX 10K devices can also be
configured using the JTAG pins through the BitBlaster serial download
cable, or ByteBlasterMV parallel port download cable, or via hardware
that uses the JamTM programming and test language. JTAG BST can be
performed before or after configuration, but not during configuration.
FLEX 10K devices support the JTAG instructions shown in Table 13.
