Product details

4.5 Mbit synchronous SRAM at 133 MHz

The CY7C1327G-133AXI: The 4 ns access time means the device can deliver data within one clock cycle at 133 MHz, keeping the read latency low for cache or buffer applications where the controller expects a deterministic response.

Industrial temperature and package fit

Housed in a 100-lead LQFP (14x20 mm body per the supplier device package), it uses a standard 0.5 mm pitch gull-wing footprint. The tray packaging means it ships in a matrix tray for pick-and-place — no reel, so plan for a tray feeder or a tube-to-reel transfer if your line is reel-fed.

Frequently asked questions

What is the memory organization of CY7C1327G-133AXI?

The device is organized as 256K words by 18 bits, giving a total memory size of 4.5 Mbit. The 18-bit word width suits designs that need parity or ECC storage alongside the data word.
