64 Mbit PSRAM with HyperBus — what it offers for the memory budget
The S27KS0642GABHI020 is a 64 Mbit Pseudo SRAM from Infineon's HyperRAM KS family, organised as 8M x 8 bits and accessed over a HyperBus interface at up to 200 MHz clock speed. With a 35 ns access time and 35 ns write cycle (word, page), this volatile PSRAM delivers SRAM-like read/write latencies without the cell area penalty of a six-transistor bitcell — useful as a code-scratch or display frame buffer in cost- and pin-constrained embedded systems.
Package, supply, and temperature — fit decisions for the board
Housed in a 24-ball VBGA (6x8 mm FBGA), the part is surface-mount with a 0.80 mm ball pitch typical of this footprint class — the 24-FBGA layout is compact enough for space-limited designs but requires controlled impedance routing for the HyperBus differential clock pair.
Active status and compliance — no last-time-buy pressure
Infineon lists the S27KS0642GABHI020 as an active product with RoHS3 compliance (lead-free, no restricted substances per the EU directive).
