The CYRS1545AV18 from Infineon Technologies is a Space Qualified Memory with storage capacity of 72 Mb density and 2M × 36 configuration with two-word burst mode. This SRAM has a maximum operating frequency of 250 MHz and a maximum operating current of 1275 mA. It is equipped with 1.8 V QDR II+ four-word burst architecture with Cypress’s state-of-the-art RadStop technology with a radiation tolerance of up to 300 Krad total dose and a latch up immunity of 110 MeV.cm2/mg. The SRAM features separate independent read and write data ports for concurrent transactions and double data rate (DDR) interfaces on both read and write ports. It requires a power supply voltage of 1.7-1.9 V and an I/O supply voltage of 1.5 V. The SRAM is available in a 165-ball Ceramic Column Grid Array (CCGA) and measures 21 × 25 × 2.83 mm. It is suitable for military applications.
