Cypress (now Infineon) no longer manufactures this FL1-K series 64 Mbit SPI NOR flash in production volume.
64 Mbit NOR flash with Quad-SPI at 108 MHz
This is a 64 Mbit (8M x 8) NOR flash memory from Cypress's FL1-K series, organized for SPI and Quad I/O operation. Write cycle time is specified at 3 ms per word or page.
24-ball BGA (8x6 mm) — fine-pitch assembly considerations
The 24-TBGA package measures 8x6 mm with a 24-ball array. This is a fine-pitch BGA requiring solder paste stencil design matched to the ball diameter and pitch. The package is surface-mount only. Rework with a hot-air station needs a bottom-side preheat to avoid cold joints on the inner balls.
Industrial temperature range for outdoor and factory gear
The 64 Mbit density is sized for firmware images, calibration tables, and data-logging buffers in systems that don't need the higher densities of the FL1-K family's 128 Mbit and 256 Mbit options.
