Product details

256K x 36 synchronous SDR SRAM at 100 MHz

The CY7C1354A-100AC is a 9Mbit synchronous SRAM organized as 256K words by 36 bits, using a single-data-rate (SDR) pipeline on a parallel interface. The 100 MHz clock and 5 ns access time mean the memory controller has exactly one clock cycle to latch the output after the address is presented — any board-level skew beyond 5 ns pushes the read window past spec.

3.3V supply and commercial temperature envelope

Supply voltage is 3.135V to 3.465V — a 3.3V nominal rail with ±5% tolerance. The controller's VDD must stay within this window; a 3.0V rail (common on some FPGAs) is below the minimum and will cause read failures.

Infineon lists the CY7C1354A-100AC as Obsolete. The package is the footprint to match; any replacement candidate must land on the same body and pinout.

Frequently asked questions

What is the replacement for the CY7C1354A-100AC?

Infineon has not published a direct replacement or cross-reference for the CY7C1354A-100AC. A pin-compatible alternative would need to match the 100-TQFP (14x20) footprint, 256K x 36 organization, 3.3V supply, and synchronous SDR interface. Without an official successor, any substitution requires a full board-level validation.
