Notes:
1. Under definition; subject to change.
2. 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.
3. Two PLLs are available in CS288 and FG484 (one PLL in FG256).
4. Available on FG484 only. FG256 and CS288 packages offer the same programmable analog capabilities as A2F200.
