72Mbit synchronous SRAM at 167 MHz — the throughput and word width
The CY7C1470BV25-167AXC: The 36-bit word width suits designs that need a wide datapath — a 32-bit processor bus with parity, or a 36-bit memory word for ECC overhead without an extra device. It belongs to the NoBL (No Bus Latency) series, a pipelined synchronous SRAM family that eliminates the dead cycle between read and write transitions on the same port. For a system that alternates read and write accesses, NoBL sustains full throughput without wait states.
The core supply is 2.375 V to 2.625 V — a nominal 2.5 V rail. The memory interface is parallel with a synchronous clock. The 167 MHz clock rate sets the peak bandwidth: at 36 bits per cycle, the raw data rate is 6.0 Gbit/s (167 MHz × 36 bits).
Package and board integration — 100-LQFP footprint
The device is supplied in a 100-lead LQFP (low-profile quad flat pack), with the supplier device package specified as 100-TQFP (14x20 mm). The 0.5 mm pitch requires a controlled-impedance PCB layout for the 36-bit data bus at 167 MHz — trace length matching and proper termination on the clock and control lines are necessary to maintain signal integrity. The package is surface-mount, shipped in tray format. The base product number is CY7C1470, which covers the 72Mbit density in the NoBL family; the suffix BV25-167AXC encodes the 2.5 V supply, 167 MHz speed grade, and commercial temperature range.
The product status is Active per Infineon's lifecycle designation. Infineon Technologies is the manufacturer. The device is a volatile SRAM (no non-volatile storage), so it requires a backup battery or supercapacitor if data retention across power loss is needed. No RoHS, REACH, or UL certification is explicitly listed in the available documentation; compliance should be confirmed against the manufacturer's latest datasheet or declaration.
