Notes:
1. Not available on A2F500 for the PQ208 package.
2. Two PLLs are available in CS288 and FG484 (one PLL in FG256 and PQ208).
3. These functions share I/O pins and may not all be available at the same time. See the "Analog Front-End Overview" section in
the
SmartFusion Programmable Analog User’s Guide
for details.
4. Available on FG484 only. PQ208, FG256, and CS288 packages offer the same programmable analog capabilities as A2F200.

Notes:
1. These pins are shared between direct analog inputs to the ADCs and voltage/current/temperature monitors.
2. 16 MSS I/Os are multiplexed and can be used as FPGA I/Os, if not needed for MSS. These I/Os support Schmitt triggers and
support only LVTTL and LVCMOS (1.5 / 1.8 / 2.5, 3.3 V) standards.
3. 9 MSS I/Os are primarily for 10/100 Ethernet MAC and are also multiplexed and can be used as FPGA I/Os if Ethernet MAC is
not used in a design. These I/Os support Schmitt triggers and support only LVTTL and LVCMOS (1.5 / 1.8 / 2.5, 3.3 V
standards.
4. 10/100 Ethernet MAC is not available on A2F060.
5. EMC is not available on the A2F500 PQ208 package.
