200 MHz SPI clock — the bus speed advantage
The Infineon S26HS512TGABHI010 is a 512 Mbit NOR Flash from the HS-T series, built for high-throughput serial read and write over an SPI interface clocked at 200 MHz. That clock rate is the headline differentiator: it lifts the sustained read throughput well above what the 133 MHz FL-S parts can sustain, which matters for fast code shadowing, OTA staging, or high-rate data logging where the serial bus is the bottleneck. Organized as 64M x 8, the 512 Mbit density fits applications needing a single-chip firmware store with room for a second boot image or a configuration file system.
Supply rail and temperature grade — fit for industrial and low-voltage systems
Rated for 1.7 V to 2 V supply, this part runs directly from a 1.8 V rail — common on modern SoCs and FPGAs — without an external regulator or level shifters on the SPI lines. If your design needs the wider -40°C to 105°C or 125°C grade, the FL-S automotive siblings (S25FL512SAGMFBG10, S25FL512SAGMFMG10) are the natural cross-shop, though they trade the 200 MHz clock for 133 MHz.
Package — 24-ball FBGA, 6x8 mm
Housed in a 24-ball FBGA (6x8 mm body, supplier package 24-FBGA), the footprint is compact enough for space-constrained PCBs but demands a controlled-impedance layout on the SPI clock and data lines. The BGA pitch is fine enough that via-in-pad and a solid ground plane under the device are recommended for signal integrity at 200 MHz. Surface-mount only; no socket option exists for this package.
The HS-T series is Infineon's high-speed serial NOR family, positioned above the FL-S automotive line in clock rate while sharing the same 512 Mbit density and SPI ecosystem.
