Notes to Table 1–3:
(1) Cyclone IV E 1.0 V core voltage devices only support C8L, C9L, and I8L speed grades. Cyclone IV E 1.2 V core voltage devices only support
C6, C7, C8, I7, and A7 speed grades.
(2) V_CCIO for all I/O banks must be powered up during device operation. All VCCA pins must be powered to 2.5 V (even when PLLs are not used)
and must be powered up and powered down at the same time.
(3) V_CC must rise monotonically.
(4) V_CCIO powers all input buffers.
(5) The I7 devices support extended operating junction temperature up to 125°C (usual range is –40°C to 100°C). When using I7 devices at the
extended junction temperature ranging from –40°C to 125°C, select C8 as the target device when designing in the Quartus^® II software. The I7
devices meet all C8 timing specifications when I7 devices operate beyond 100°C and up to 125°C.
(6) The POR time for Standard POR ranges between 50 and 200 ms. Each individual power supply must reach the recommended operating range
within 50 ms.
(7) The POR time for Fast POR ranges between 3 and 9 ms. Each individual power supply must reach the recommended operating range within
3 ms.
