The Infineon CY7C1308DV25C-167BZCT is officially marked Obsolete. This means the manufacturer has discontinued production and no longer supports new orders through the standard supply chain. A board-level redesign may be required for a functional substitute.
9 Mbit DDR SRAM at 167 MHz
This is a 9 Mbit synchronous DDR SRAM organized as 256K x 36. The 167 MHz clock frequency delivers double-data-rate transfers on each clock edge, effectively doubling the read/write bandwidth compared to a single-data-rate part at the same clock. The 36-bit wide data bus suits high-throughput applications like network buffers, cache controllers, and DSP memory. Operating from a 2.4 V to 2.6 V supply, it runs at a lower core voltage than legacy 3.3 V SRAM, reducing dynamic power.
165-ball FBGA package — board integration
Housed in a 165-ball LBGA with a supplier device package of 165-FBGA measuring 13x15 mm. This fine-pitch BGA requires a multi-layer PCB with controlled impedance traces for the 167 MHz DDR interface. The tape-and-reel packaging is suited for automated pick-and-place assembly.
