Overview
Ultra37000 CPLD Family 5V, 3.
3V, ISR™ High-Performance CPLDs Features • In-System Reprogrammable™ (ISR™) CMOS CPLDs — JTAG interface for reconfigurability — Design changes do not cause pinout changes — Design changes do not cause timing changes • High density — 32 to 512 macrocells — 32 to 264 I/O pins — Five dedicated inputs including four clock pins • Simple timing model — No fanout delays — No expander delays — No dedicated vs.
I/O pin delays — No additional delay through PIM — No penalty for using full 16 product terms • • • • — No delay for steering or sharing product terms 3.
3V and 5V versions PCI-compatible[1] Programmable bus-hold capabilities on all I/Os Intelligent product term allocator provides: — 0 to 16 product terms to any macrocell — Product term steering on an individual basis — Product term sharing among local macrocells • Flexible clocking — Four synchronous clocks per device — Product term clocking — Clock polarity control per logic block • Consistent package/pinou...
