The CY7C199D-10ZXI is a 256Kbit asynchronous SRAM organized as 32K x 8 bits, with a 10 ns access time and a matching 10 ns write cycle time (word, page).
The parallel memory interface requires 32 address lines and 8 data lines, plus control signals (chip enable, output enable, write enable) — a straightforward layout for a 32-bit microcontroller or FPGA bus.
Yes, Infineon has classified the CY7C199D-10ZXI as Obsolete. It is no longer manufactured and must be sourced through surplus or broker channels.
For a pin-compatible alternative, consult the CY7C199 family base product number — parts with the same 28-TSOP I footprint and 5V supply may serve as drop-in replacements, but verify the access time and temperature grade against your design.
