Figure 1–8 shows the PCB routing for the 88-pin UFBGA package. The Gerber file for

this layout is on the Altera website.

Package Layout Recommendation

Sharp flash-based EPC16 and EPC8 enhanced configuration devices in the 100-pin

PQFP packages have different package dimensions than other Altera 100-pin PQFP

devices (including the Micron flash-based EPC4, Intel flash-based EPC16, EPC8 and

EPC4). Figure 1–9 shows the 100-pin PQFP PCB footprint specifications for enhanced

configuration devices that allows for vertical migration between all devices. These

footprint dimensions are based on vendor-supplied package outline diagrams.

Notes to Figure 1–8:

(1) If the external flash interface feature is not used, then the flash pins should be left unconnected because they are internally connected to the

controller unit. The only pins that need external connections are WP#, WE#, and RP#. If the flash is being used as an external memory source,

then the flash pins should be connected as outlined in the pin descriptions section.

(2) F-RP# and F-WE# are pins on the flash die. C-RP# and C-WE# are pins on the controller die. C-WE# and F-WE# should be connected together

on the PCB. F-RP# and C-RP# should also be connected together on the PCB.

(3) WP# (write protection pin) should be connected to a high level (3.3 V) to be able to program the flash bottom boot block, which is required when

programming the device using the Quartus II software.

(4) RY/BY# is only available in Sharp flash-based enhanced configuration devices.

(5) Pin D3 is a NC pin for Intel Flash-based EPC16.
