Product details

36 Mbit DDR II+ SRAM at 400 MHz — what it buys you

The CY7C1250KV18-400BZC is a 36 Mbit synchronous SRAM from Infineon (formerly Cypress) using the DDR II+ architecture, organized as 1M x 36 and clocked at 400 MHz. The DDR II+ interface delivers back-to-back read/write transactions every clock edge — no dead cycles on the bus — which matters when the memory sits between a high-throughput ASIC or FPGA and a 36-bit data path.

400 MHz clock — bus timing headroom

At 400 MHz the clock period is 2.5 ns. The DDR II+ interface samples data on both edges, so the effective data rate is 800 MT/s per pin. For a 36-bit word that is 3.2 GB/s of raw bandwidth. The synchronous pipeline keeps output valid across the full clock cycle, which relaxes the setup/hold budget at the controller side — useful when trace lengths push beyond 50 mm on the FBGA breakout.

Package and supply — layout checklist

The 165-FBGA (13×15 mm) is a fine-pitch BGA — expect 1.0 mm ball pitch or finer.

Frequently asked questions

Does CY7C1250KV18-400BZC have a RoHS compliant version?

The evidence does not specify RoHS compliance status for this exact order code. Confirm with the manufacturer or distributor at quote time.

What is the difference between CY7C1250KV18-400BZC and CY7C1250KV18-400BZX?

The suffix difference typically indicates a packaging variant (e.g., tray vs tape-and-reel, or lead-free vs standard finish). The evidence does not detail the exact delta. Verify the specific suffix meaning against the Cypress/Infineon ordering guide.
