Product details

133 MHz synchronous SRAM for harsh environments

The CY7C1339G-133AXE: This is a 4Mbit synchronous SDR SRAM organised as 128K x 32, clocked at 133 MHz with a 4 ns access time.

100-TQFP footprint and board fit

The 100-TQFP (14x20 mm) package is a common surface-mount footprint for mid-density SRAM. The parallel interface simplifies timing closure compared to a DDR variant, but the bus width occupies 32 data lines plus address and control.

Sourcing reality for an obsolete line

Sourcing is limited to independent distributors and the open market.
