The 100-TQFP (14x20 mm) package with 0.5 mm pitch requires a controlled impedance layout on the data and address lines to maintain signal integrity at 133 MHz. Infineon has classified the CY7C1339G-133AXC as obsolete. No official successor or pin-compatible replacement is recorded from the manufacturer.","metaTitle":"Infineon CY7C1339G-133AXC 4Mbit Sync SRAM, 133 MHz, 100-LQFP","metaDescription":"CY7C1339G-133AXC 4Mbit synchronous SRAM, 133 MHz clock, 4 ns access, 128K x 32, 100-LQFP.
