The CY7C1363D-133AXI is marked obsolete by Infineon Technologies.
The CY7C1363D-133AXI is a 9 Mbit synchronous SDR SRAM organized as 512K words by 18 bits. The 133 MHz clock frequency yields a 6.5 ns access time, placing it in the mid-speed tier for synchronous SRAMs of this density. The industrial temperature range (-40 °C to 85 °C) suits it for factory-floor controllers, telecom line cards, and other thermally demanding environments.
Housed in a 100-lead LQFP (supplier device package 100-TQFP, 14x20 mm body), the part is surface-mount and supplied in tray packaging. The 0.5 mm pitch requires a controlled impedance layout for the parallel bus; the wide body provides adequate breakout room on a four-layer board. The parallel interface simplifies integration with legacy FPGA or ASIC designs that lack a high-speed serial memory controller.
