The 24-ball BGA package (8x6 mm body) keeps the footprint compact for space-constrained PCB layouts.
104 MHz Quad-SPI — what the clock rate means for your design
The 104 MHz clock on the Quad I/O interface gives a theoretical peak read throughput around 52 MB/s in quad mode. That is enough to feed a Cortex-M or low-end application processor without stalling on instruction fetches, provided the controller's SPI peripheral can sustain the rate. The page program time is 5 µs typical and the sector erase runs 3 ms typical — write-heavy workloads like over-the-air update staging need to budget for those latencies, especially if the erase granularity (4 KB or 64 KB sectors) forces larger erase cycles than the data size warrants.
Cypress (now Infineon) has ended production, so the only available stock moves through independent distribution and surplus channels. The 24-ball BGA package means MSL handling and bake requirements apply — verify moisture sensitivity before reflow if the parts have been in storage.
