108 MHz SPI NVSRAM — no battery, no worry
The Cypress CY14V101QS-BK108XI is a 1 Mbit Non-Volatile SRAM (NVSRAM) that combines the fast read/write of SRAM with non-volatile storage — no external battery needed. It talks over a standard SPI bus at up to 108 MHz, organized as 128 Kbytes x 8 bits.
108 MHz clock — what it buys you
The 108 MHz SPI clock is the standout number here. Compared to the FM25VN10-G FRAM at 40 MHz or the CY15B102Q-SXET at 25 MHz, this part can transfer a full 128 Kbyte page in roughly 9 ms versus 25–50 ms on those alternatives. That matters for high-speed data logging or caching writes in a motor-drive or industrial controller where the bus is shared.
The 24-FBGA (6x8 mm) is a fine-pitch BGA — not something you swap with a standard iron on site. If you are stocking a field-repair kit, plan for a hot-air station and a stencil. The Tray shipping medium means it arrives in antistatic trays, not tape and reel, so handle with ESD precautions.
