A 15 ns part is fast enough for most 8-bit and 16-bit microcontrollers running at 20–40 MHz, but a 10 ns or 12 ns sibling would be needed if the bus cycle is tighter than 20 ns. Cypress (now part of Infineon) no longer manufactures this device. ## Package and footprint: 28-SOJ This is a surface-mount, J-lead package with a 1.27 mm pitch. The SOJ footprint is less common than TSOP but was widely used in 1990s–2000s SRAM and logic designs. The shipping medium is Tube. ## Temperature grade: commercial only If the application sees temperature extremes, a different SRAM with an extended temperature range is needed.","metaTitle":"Cypress CY7C192-15VXC 256Kbit Asynchronous SRAM, 15 ns","metaDescription":"Cypress CY7C192-15VXC 256Kbit (64K x 4) asynchronous SRAM with 15 ns access time, 4.5–5.5V supply, 28-SOJ package, 0–70°C.
