The Infineon CY7C1371DV33-133BZI is a 18Mbit synchronous SRAM from the NoBL™ family, organized as 512K x 36 and clocked at 133 MHz with a 6.5 ns access time.
CY7C1371DV33-133BZI carries an Obsolete lifecycle status, meaning Infineon has ended production and no further factory orders are accepted.
133 MHz clock and 6.5 ns access — timing closure for the memory controller
The 133 MHz clock sets the synchronous interface rate; the 6.5 ns access time is the delay from address assertion to valid data on the bus.
Industrial temperature and supply tolerance
The 3.135V to 3.6V supply covers the 3.3V nominal rail with margin for ripple and load transients — no external regulator needed if the board's 3.3V rail stays within that window.
