QDR II synchronous SRAM — 144 Mbit at 250 MHz
The CY7C1612KV18-250BZXC is a 144 Mbit Quad Data Rate (QDR) II synchronous SRAM organized as 8M x 18 bits. It clocks at 250 MHz, delivering two data transfers per clock edge on both read and write ports for a peak bandwidth of 9 GB/s on the 18-bit bus. The commercial temperature grade (0°C to 70°C) fits indoor equipment; for extended temperature variants, check the broader CY7C1612 family.
Package and board-fit — 165-ball FBGA
Housed in a 165-ball LBGA (15x17 mm body per the supplier device package), the footprint is a 1.0 mm ball pitch array. The tray delivery means the parts arrive in matrix trays — not tape-and-reel — so the pick-and-place feeder setup and tube/tray handler configuration need to account for that. The parallel memory interface uses separate read and write data ports — QDR II architecture — so the PCB routing must maintain matched trace lengths between the controller and the SRAM for both ports at 250 MHz. The 1.8V core supply should be decoupled with low-ESR MLCCs at each VDD ball pair.
