The 15 ns access time is fast enough for 5V legacy bus architectures running at 33 MHz or slower without wait states, provided the board trace delay and capacitive loading stay within the timing budget. Procurement for the CY7C199C-15VC is handled through independent distribution and surplus channels. ## Package and temperature — 28-SOJ with commercial range The SOJ footprint is a legacy form factor; any drop-in replacement must match this mechanical outline and pinout.","metaTitle":"CY7C199C-15VC 256Kbit Asynchronous SRAM 15 ns SOJ-28","metaDescription":"Infineon CY7C199C-15VC 256Kbit (32K x 8) asynchronous SRAM, 15 ns access time, 4.5V-5.5V supply, 0°C-70°C, 28-SOJ.
