The 250 MHz clock rate delivers two data transfers per cycle (on both rising and falling edges), giving an effective bandwidth of 500 million transactions per second on each of the read and write ports.
The core supply operates from 1.7V to 1.9V, a narrow window that demands a clean, well-regulated rail — a 1.8V LDO or switching regulator with tight load regulation is the typical choice. The 1.9V ceiling means the memory is not tolerant of 2.5V or 3.3V I/O; the interface is strictly 1.8V HSTL-class signalling.
Package and board-level handling
The base product number CY7C1412 covers the full density and speed range; the -250BZI suffix specifies the 250 MHz speed grade in the industrial-temperature FBGA package.
