Frequently Asked Questions
What is the memory organization and maximum clock speed of the IS42S32800D-7BLI?
The IS42S32800D-7BLI is organized as 8 M x 32 bits, providing 256 Mbit of total capacity accessible via a 32-bit data bus at up to 143 MHz. The four-bank architecture and selectable burst lengths of 1, 2, 4, and 8 cycles maximize sequential read and write throughput for embedded processors and FPGA memory interfaces.
How does the four-bank burst architecture of the IS42S32800D-7BLI improve throughput in DSP and media processing designs?
The four-bank architecture enables the IS42S32800D-7BLI to pipeline row activate and precharge operations between banks, reducing effective latency during sustained 32-bit transfers at 143 MHz. With burst length set to 8, each burst transfers 256 bits per access cycle, improving throughput for DSP algorithms and video codec implementations that rely on sequential memory block reads.
When is IS42S32800D-7BLI preferred over DDR SDRAM alternatives in legacy industrial embedded designs?
The IS42S32800D-7BLI operates from a single 3.3 V supply with standard SDRAM timing, making it compatible with legacy FPGAs and microprocessors that lack DDR memory controllers. Its -40°C to +85°C industrial temperature range and 90-ball FBGA package provide a mature, well-characterized memory solution where DDR2 or DDR3 interface complexity or power requirements cannot be accommodated.
