Frequently asked questions
Is the CY7C1399BNL-15VXC obsolete?
Yes — the lifecycle stage is end-of-life hot under. Standard distribution is no longer active; sourcing is allocation recovery or broker channel only.
Does the 3 V–3.6 V supply handle brownout to 2.9 V?
No. The operating minimum is 3 V — a 2.9 V brownout during a motor-stall event falls outside the rated window and risks data corruption. The design needs a hold-up circuit or supply supervision if that event is a real-world case.
Is 15 ns access time compatible with a 50 MHz FPGA interface?
Yes. 50 MHz gives a 20 ns cycle; 15 ns access is well within that window. Write cycle time is also 15 ns symmetric, so a single firmware timing budget covers both read and write operations.
