It operates from a 4.5 V to 5.5 V supply and is housed in a 22-pin PDIP through-hole package. This is a commercial-temperature (0 °C to 70 °C) part, intended for indoor, non-condensing environments — think legacy industrial controllers, test equipment, or retrofitting an old CPU board that needs a fast scratchpad. The 15 ns access time means it can keep up with a moderately fast bus without wait states, but the 64Kbit density limits it to small cache or status-flag storage, not a main memory array. ## Through-hole PDIP — integration note The 22-PDIP package is through-hole, 0.300-inch body width. It fits standard DIP sockets or can be soldered into plated-through holes.","metaTitle":"Cypress CY7C187-15PXC 64Kbit Asynchronous SRAM, 15 ns","metaDescription":"Cypress CY7C187-15PXC 64Kbit asynchronous SRAM, 15 ns access time, 64K x 1 organization, parallel interface, 4.5-5.5 V, 22-PDIP.
