If the system uses a 100 MHz or faster bus clock, the 10 ns window starts to pinch — you will need to check the address-to-data setup and hold against the controller's AC timing table. Because the CY7C1049G-10ZSXIT is in Last Buy status, the primary channel is the factory LTB order. After that window closes, availability will shift to independent distribution and surplus stock. If you have a BOM line that needs filling, send the RFQ and we will check the open-market inventory and factory LTB allocation.","metaTitle":"CY7C1049G-10ZSXIT 4Mbit Async SRAM, 10 ns, 44-TSOP II","metaDescription":"Infineon CY7C1049G-10ZSXIT 4Mbit asynchronous SRAM, 512K x 8, 10 ns access time, 4.5V-5.5V, -40°C to 85°C, 44-TSOP II.
