&& PREVIOUS FINALIST | MAIN | NEXT FINALIST >> Category: Logic and Interface ICs Finalist: 26 series SQI (serial quad I/O) (SST)  The SST 26 Series Serial Quad I/O™ (SQI™) family consists of 4-bit multiplexed I/O serial interface flash memory devices. With an 80 MHz operating frequency and specialized instruction set, the devices target execute-in-place (XiP) applications, allowing programs to be stored and executed directly from flash memory without the need for code shadowing on an SRAM; increasing overall system performance. Its low pin count and enhanced serial interface architecture make the family an ideal code storage solution for applications where small form factor, low power consumption and high data rate are a must.The 26 Series family was designed to deliver many of the performance advantages system designers working with parallel flash memories have come to expect while retaining the low pin-count, low-power and low-cost advantages of serial flash. With sustained burst data rates of up to 320 Mbit/sec., the devices provide serial flash performance exceeding that of typical parallel flash memory. To reduce access time, the devices support 8-, 16-, 32- and 64-Byte burst mode operation with wrap around, allowing designers to execute code in burst snippets for RAM-less applications or fill cache line buffers for applications where the system architecture uses pipelining to maximize bus bandwidth. The SQI architecture allows designers to use the memory in continuous burst mode for applications requiring variable code sizes both with and without a cache line architecture. |
