Product details

36Mbit QDR II+ SRAM at 550 MHz — what it is and where it fits

The Infineon CY7C1263KV18-550BZXC is a 36Mbit synchronous SRAM built on QDR II+ architecture, organized as 2M words by 18 bits. It clocks at 550 MHz on the parallel interface.

550 MHz clock — what it means for the bus

At 550 MHz, the QDR II+ interface eliminates the dead cycles between read and write turns that older NoBL or DDR SRAMs leave on the table.

Lifecycle reality — EOL phase, plan the last buy

The CY7C1263KV18-550BZXC carries an EOL-hot lifecycle stage. That means Infineon has notified the end-of-life — the last-time-buy window is either open or closing. For a BOM that depends on this exact density and speed grade, the procurement move is to secure final-order quantities now rather than chase dwindling surplus later. No official successor order code is listed in the lifecycle record, so a pin-compatible drop-in is not confirmed.

Frequently asked questions

Is CY7C1263KV18-550BZXC obsolete or nearing end-of-life?

Yes, the CY7C1263KV18-550BZXC carries an EOL-hot lifecycle stage, meaning Infineon has initiated the end-of-life process. The last-time-buy window is active or closing — secure final quantities through an RFQ rather than assuming ongoing production availability.

What is the direct replacement for CY7C1263KV18-550BZXC?

No official successor order code is listed in the lifecycle record for this exact 36Mbit, 550 MHz, 165-FBGA variant. A pin-compatible drop-in from the same QDR II+ family is not confirmed. For a like-for-like replacement, a cross-reference search against the 36Mbit QDR II+ portfolio is the next step, but the safest procurement path is a last-time-buy of this part number.

What is the operating voltage range for CY7C1263KV18?

The supply voltage range is 1.7V to 1.9V, which is the standard core rail for 1.8V-class QDR II+ SRAMs. The parallel interface operates at the same voltage, so the FPGA or ASIC port must match this I/O level.

What is CY7C1263KV18-550BZXC's listed technology?

It is a synchronous SRAM using QDR II+ (Quad Data Rate II+) architecture, organized as 2M words by 18 bits for a total of 36Mbit. The QDR II+ interface allows simultaneous read and write on separate ports, eliminating bus-turnaround dead cycles.
