ISSI NOR Flash ICs are Serial Peripheral Interface (SPI) Flash memories, providing single, dual, or quad output. ISSI NOR Flash ICs use a single low voltage power supply to perform read, erase and program operations. The devices can be programmed in standard EPROM programmers. These devices are accessed through a 4-wire SPI Interface consisting of Serial Data Input/Output (SIO), Serial Data Output (SO), Serial Clock (SCK), and Chip Enable (CE#) pins. The 25LD family offers highest performance & endurance of 200K cycles and 20 years of solid data retention. The IS25LD/WD family supports Dual-SPI effectively doubling standard SPI clock rates, and the IS25 LQ/WQ family supports single, Dual-I/O, and Quad-I/O for even higher performance. These parts can support up to 104MHz an equivalent of 416Mhz (50Mb/sec throughput) when using Quad mode.
ISSI IS43LR16800F 2Mx16 Mobile DDR SDRAM is 134,217,728 bits Mobile Double Data Rate (DDR) Synchronous DRAM (SDRAM) organized as 4 banks of 2,097,152 words x 16 bits. This product uses a double-data-rate architecture to achieve high-speed operation. The Data Input/ Output signals are transmitted on a 16-bit bus. The double data rate architecture is essentially a 2N prefetch architecture with an interface designed to transfer two data words per clock cycle at the I/O pins. This product offers fully synchronous operations referenced to both rising and falling edges of the clock.
