ISSI Featured Products

ISSI Pseudo SRAM/CellularRAM

ISSI Pseudo SRAM (PSRAM)/CellularRAM™ offers designers an option of the best of both DRAM and SRAM features. The PSRAM/CellularRAM has a SRAM-like architecture. Unlike DRAM, there is a hidden refresh feature which does not require physical refresh. The CellularRAM is designed in accordance to the CellularRAM standards and is available in CRAM 1.5 and CRAM 2.0. This family of products offers fast access, asynchronous, page and burst functions for different application requirements. The products support low voltage which reduces over all power consumption. These products are available in commercial, industrial and automotive operating temperature range, which is suitable to support applications in these markets.

ISSI Mobile DDR SDRAM

ISSI Mobile DDR SDRAM is organized as 4 banks of 16,777,216 words x 16 bits and 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. ISSI Mobile DDR SDRAM offers fully synchronous operations referenced to both rising and falling edges of the clock. The data paths are internally pipelined and 2n-bits prefetched to achieve very high bandwidth. All input and output voltage levels are compatible with LVCMOS.

ISSI Asynchronous SRAM

ISSI high speed low power asynchronous SRAM is a 8M-bit static RAM organized as 512K words by 16 bits. It is fabricated using ISSI's high-performance CMOS technology. This highly reliable process coupled with innovative circuit design techniques, yields high-performance and low power consumption devices. When CE is HIGH (deselected), the device assumes a standby mode at which the power dissipation can be reduced down with CMOS input levels. Easy memory expansion is provided by using Chip Enable and Output Enable inputs, CE and OE. The active LOW Write Enable (WE) controls both writing and reading of the memory. A data byte allows Upper Byte (UB) and Lower Byte (LB) access. The device is packaged in the 44-pin TSOP (Type II).

ISSI IS43TRx 2GB DDR3 SDRAMs

These devices operate at 1.5V (IS43TR16640A) or 1.35V (IR43TR16640AL) and are available with clock speeds up to 800MHz. By using advanced technology, ISSI is able to provide the long lifecycle product support as required by applications in automotive, communications, industrial, medical and mil-aerospace. Typical applications include access nodes, aggregation nodes, switches, routers, packet optical transport, network storage, infotainment, telematics, driver information systems, human machine interface, and embedded computing.

ISSI NOR Flash ICs

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.
