Product details
Overview
7005S17G from IDT is a high-speed 8K × 8 true dual-port static RAM with independent left/right ports, 17 ns maximum access time (commercial grade), TTL-compatible 5 V ±10% supply, and on-chip semaphore/arbitration logic for inter-port synchronization in real-time shared-memory systems.
For engineers reviewing the 7005S17G datasheet, 7005S17G pinout, 7005S17G application, or 7005S17G equivalent, key selection criteria include simultaneous read capability, BUSY/INT flag timing, M/S master/slave cascading support, and 64-pin TQFP package compatibility with industrial temperature operation.
Technical Context
The 7005S17G implements fully asynchronous dual-port architecture with separate address, data, and control lines per port (A0L–A12L/I/O0L–I/O7L/R/WL/CEL/OEL/BUSYL/INTL/SEML on left; symmetric right-side signals). It supports true concurrent reads from the same memory location without contention.
On-chip hardware includes port arbitration logic that asserts BUSY when address/control conflicts occur, semaphore registers (8 flags addressed via A0–A2), and interrupt flag generation (INTL/INTR) triggered by write to specific addresses (e.g., 1FFFH sets INTR). M/S pin configures master (BUSY output) or slave (BUSY input) mode for multi-device expansion.

Applications
| Real-Time Digital Signal Processing | Industrial Motion Control |
|---|---|
Use Scenario: Dual-processor DSP system where one CPU handles ADC sampling while another executes FFT algorithms on shared buffer memory. IC Role / Device Role / Timing Role: 7005S17G serves as zero-wait-state shared memory with simultaneous read capability - left port feeds sampled data, right port supplies processed results. Use Value: Eliminates DMA handshaking delays; 17 ns access ensures pipeline continuity at 50+ MHz processor clock rates. | Use Scenario: CNC controller with separate motion trajectory planner and servo loop executor accessing common position/velocity tables. IC Role / Device Role / Timing Role: 7005S17G acts as synchronized parameter store - planner writes updated paths, servo reads in real time with BUSY arbitration preventing mid-update corruption. Use Value: Hardware semaphore (SEML/SEMR) guarantees atomic updates to critical motion parameters without software mutex overhead. |
| Avionics Data Acquisition | Telecom Packet Buffering |
Use Scenario: Modular avionics unit acquiring sensor data (pressure, temp, attitude) and forwarding to flight management computer via ARINC 429 interface. IC Role / Device Role / Timing Role: 7005S17G functions as dual-port FIFO buffer - left port accepts sensor streams, right port feeds ARINC transmitter under interrupt-driven control (INTL/INTR). Use Value: Interrupt flags eliminate polling; 17 ns access meets DO-254 deterministic timing requirements for safety-critical data transfer. | Use Scenario: Base station line card buffering Ethernet frames between MAC layer and PHY transceiver, requiring low-latency inter-processor coordination. IC Role / Device Role / Timing Role: 7005S17G operates as shared packet descriptor table - one ARM core manages ingress queues, another handles egress scheduling with semaphore-controlled access. Use Value: On-chip arbitration prevents descriptor corruption during concurrent queue operations; 64-pin TQFP fits dense RF board layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C024AV-15AXC | 15 ns access, 8K × 16 organization, 100-pin TQFP - wider data bus but larger footprint and higher power (220 mA active) | Requires fewer devices for 16-bit systems but lacks M/S cascading; no native semaphore logic | Select when 16-bit word width is mandatory and board area permits larger package |
| IS61LV25616AL-10TLI | 10 ns access, 256K × 16, 48-pin TSOP - faster and higher density but single-port only; requires external arbitration logic | Not suitable for true dual-access scenarios; needs discrete semaphores and BUSY logic | Choose only if application uses sequential port access and board space constraints favor smaller package |
Compared with CY7C024AV-15AXC and IS61LV25616AL-10TLI, the 7005S17G uniquely delivers true dual-port operation with integrated arbitration and semaphore in a compact 64-pin TQFP - essential for real-time systems requiring deterministic inter-processor communication without external logic.

FAQ
What is the maximum operating frequency supported by the 7005S17G?
The 7005S17G does not specify a maximum clock frequency because it is an asynchronous SRAM. Its performance is defined by access timing: 17 ns maximum read cycle time (tRC) and address access time (tAA) under commercial conditions. System-level throughput depends on controller timing margins and bus protocol - typical sustained bandwidth exceeds 50 MB/s per port when interfaced with FPGA or microcontroller peripherals supporting 17 ns strobe widths.
Does the 7005S17G support battery backup for data retention?
No, the 7005S17G is the standard-power "S" variant and does not support battery backup. Data retention capability (2 V minimum VCC, 100 µA typical ICCDR) is exclusive to the "L" version (e.g., 7005L17G). The 7005S17G requires continuous 5 V ±10% supply for volatile operation; loss of VCC results in immediate data loss.
How does the M/S pin affect BUSY signal behavior in the 7005S17G?
When M/S = HIGH, the 7005S17G operates as a master: BUSYL and BUSYR are push-pull outputs that assert LOW during port arbitration conflicts. When M/S = LOW, it operates as a slave: BUSYL and BUSYR become inputs that must be driven LOW by an external master to inhibit writes - the 7005S17G itself does not drive BUSY in slave mode. This enables hierarchical multi-device memory expansion.
Can the 7005S17G perform simultaneous read and write operations on different memory locations?
Yes, the 7005S17G supports fully independent asynchronous access: one port can read from address 0x1234 while the other writes to address 0x5678 with no timing penalty or conflict. BUSY arbitration only activates when both ports attempt access to the same address with overlapping control signals - unrelated addresses operate concurrently at full 17 ns speed.
What are the voltage thresholds for reliable operation of the 7005S17G control inputs?
The 7005S17G specifies VIH = 2.2 V min and VIL = 0.8 V max for all control inputs (CEL, OEL, R/WL, etc.) under commercial conditions. Inputs driven below 0.8 V are guaranteed recognized as logic LOW; those above 2.2 V are guaranteed recognized as logic HIGH. Operation outside these thresholds risks metastability or incorrect state detection - design must ensure clean TTL-level transitions.
