Frequently Asked Questions
What is the memory density and data width of the IDT70V3599S133BCGI?
The IDT70V3599S133BCGI has a total memory density of 4,718,592 bits (approximately 4.5 Mb) organized with a 36-bit wide data bus. This 36-bit width accommodates 32 data bits plus 4 parity or ECC bits, providing error detection capability in memory-critical applications such as telecommunications switching and real-time signal processing.
What clock frequency and access time does the IDT70V3599S133BCGI support?
This multi-port SRAM supports a maximum clock frequency of 133 MHz with a maximum access time of 15 ns in pipelined mode. The selectable pipelined or flow-through architecture allows designers to choose between maximum throughput at 133 MHz pipeline mode or lower-latency flow-through operation depending on system requirements.
In which package does the IDT70V3599S133BCGI come and how does it affect PCB routing?
The IDT70V3599S133BCGI is housed in a 256-ball BGA package (JESD-30 Code: S-PBGA-B256), which provides a compact footprint suitable for high-density PCB designs. The BGA package requires controlled-impedance PCB traces and micro-via fanout routing, but enables significantly shorter signal paths compared to TQFP alternatives, supporting signal integrity at 133 MHz operation.
When would IDT70V3599S133BCGI be preferred over a single-port SRAM in a multi-processor design?
The IDT70V3599S133BCGI multi-port SRAM is preferred when two or more processors need concurrent access to the same 4.5 Mb memory space without bus arbitration overhead. In single-port SRAM designs, only one processor can access memory per clock cycle, limiting throughput; the multi-port architecture eliminates this bottleneck by providing independent 36-bit ports operating simultaneously at 133 MHz.
