The CY7C1370CV25-167AC is classified as Obsolete by Infineon Technologies. No official successor or pin-compatible replacement is recorded on the manufacturer's lifecycle documentation. For existing BOM lines, this part is sourced through independent distribution channels.
Memory organization and speed grade
This is a 18 Mbit synchronous SRAM organized as 512K words by 36 bits. The 36-bit word width suits systems requiring parity or ECC storage alongside the data bus — a common fit for networking buffers and telecom line cards where the extra 4 bits per word carry the check code. The 3.4 ns access is the time from the clock edge to valid data on the output pins; at 167 MHz the cycle period is 6 ns, so the access time consumes just over half the cycle, leaving margin for board trace delay and input setup at the FPGA or ASIC.
Operates from a 2.375 V to 2.625 V core supply — a tight 250 mV window that demands a regulated rail. A 2.5 V LDO with ±2% accuracy keeps the SRAM within spec; a 2.5 V switching regulator with 1% ripple is acceptable if the output capacitor bank handles the transient load step. This limits deployment to indoor, temperature-controlled environments — telecom central offices, data-centre switches, and lab instrumentation. Not rated for industrial or automotive ambient extremes.
Supplied in a 100-lead LQFP (also designated 100-TQFP, 14x20 mm body). Surface-mount assembly with a standard JEDEC moisture sensitivity level (MSL) profile for LQFP. The bag packaging indicates the parts ship in anti-static bags; no reel or tray quantity is specified, so per-unit handling and bake requirements follow the lot-specific MSL label.
