What this 18Mbit synchronous SRAM is and where it fits
The CY7C1371C-100AC is a 18Mbit synchronous SRAM from Infineon's NoBL™ (No Bus Latency) series, organized as 512K x 36 bits. It runs on a 3.135V to 3.6V supply and is rated for the commercial temperature range of 0°C to 70°C. With a 100 MHz clock and 8.5 ns access time, this part is designed for high-throughput parallel memory interfaces in networking, telecom, and industrial control systems where the CPU or ASIC needs fast, predictable read/write cycles without wait states.
Lifecycle reality — obsolete, sourced to order
Infineon lists the CY7C1371C-100AC as Obsolete. No official successor or pin-compatible replacement is recorded in the available documentation.
Housed in a 100-lead LQFP (supplier device package 100-TQFP, 14x20 mm body), the part is surface-mount and intended for reflow soldering. The 0.50 mm pitch demands careful PCB layout for fan-out and signal integrity at 100 MHz.
