Product details
Overview
5962-8687504XA from Integrated Device Technology (IDT) is a military-grade 1K × 8 dual-port static RAM with on-chip arbitration logic, 25ns/35ns access time options, TTL-compatible 5V ±10% operation, and -55°C to +125°C operating range. It functions as a MASTER device in MASTER/SLAVE memory expansion configurations for real-time avionics and radar signal processing systems.
For engineers reviewing the 5962-8687504XA datasheet, 5962-8687504XA pinout, 5962-8687504XA application, or 5962-8687504XA equivalent, key selection criteria include BUSY-flag arbitration timing, port-to-port interrupt capability, MIL-PRF-38535 QML qualification, and compatibility with IDT7140 SLAVE devices in 16-bit-or-wider memory subsystems.
Technical Context
The 5962-8687504XA implements fully asynchronous dual-port architecture with independent left/right address, control, and I/O buses. Its on-chip arbitration logic resolves simultaneous access contention via BUSY output assertion and supports priority-based write inhibition when address matches occur across ports.
It features open-drain BUSY outputs requiring external pull-up resistors, INT/INTR flag signaling for inter-port communication, and battery backup data retention (2V, 100–4000 µA) in LA variants - though 5962-8687504XA is SA-rated and excludes retention mode per MIL-PRF-38535 Class V requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1K × 8 bits (1024 words × 8-bit wide), enabling compact buffer storage in space-constrained embedded systems. |
| Access Time | 25ns max (military grade), guaranteeing deterministic read/write latency for real-time command-and-control applications. |
| Supply Voltage | 5.0V ±10%, compatible with legacy TTL logic families and eliminating need for voltage translation in mixed-signal boards. |
| Operating Temperature | -55°C to +125°C, qualified per MIL-PRF-38535 QML Class V for deployment in harsh aerospace and defense environments. |
| Arbitration Logic | On-chip port arbitration with BUSY flag generation, enabling conflict-free concurrent access without external glue logic. |
| Interrupt Support | Dedicated INTL/INTR pins for hardware-triggered inter-port signaling, simplifying synchronization in multi-processor architectures. |
| Power Consumption | Active current ≤110mA (typ), standby current ≤30mA (ISB1, TTL-level inputs), supporting low-duty-cycle mission profiles. |
Pinout & Package
5962-8687504XA is packaged in a 48-pin ceramic flatpack (FP48) compliant with MIL-STD-1835, measuring approximately 0.75 in × 0.75 in × 0.11 in.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A9L | Left port address inputs | 10-bit address bus for accessing left-side memory locations; must be stable before CE/WE assertion. |
| A0R–A9R | Right port address inputs | 10-bit address bus for right-side access; independent timing allows pipelined dual-port operation. |
| I/O0L–I/O7L | Left port bidirectional data | 8-bit data path; high-impedance when OEL = VIH or during write cycles with R/WL = L. |
| I/O0R–I/O7R | Right port bidirectional data | 8-bit data path; electrically isolated from left port to prevent bus contention. |
| CEL / CER | Chip enable (left/right) | Active-low enables respective port; deassertion places port in low-power standby (ISB1/ISB2). |
| OEL / OER | Output enable (left/right) | Active-low controls I/O drivers; used to tri-state outputs during shared-bus multiplexing. |
| R/WL / R/WR | Read/write control (left/right) | High = read, low = write; determines direction of data flow on associated I/O bus. |
| BUSYL / BUSYR | Arbitration status (open-drain) | Asserted low when opposite port accesses same address; requires external 4.7kΩ pull-up for proper logic level. |
| INTL / INTR | Interrupt request (input/output) | INTL is output (left port sets INTR); INTR is input (right port sets INTL); enables cross-port event signaling. |
| VCC / GND | Power supply | All VCC pins must be decoupled with 0.1µF ceramic capacitors near package; all GND pins tied to common ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| MASTER/SLAVE expandability | Enables seamless 16-bit+ data bus width extension using IDT7140 SLAVE devices without additional arbitration logic. |
| Asynchronous dual-port operation | Eliminates clock domain crossing issues and supports independent timing on each port for heterogeneous processor interfacing. |
| MIL-PRF-38535 QML Class V compliance | Guarantees radiation hardness, burn-in screening, and lot traceability required for flight-critical avionics systems. |
| Open-drain BUSY outputs | Allows wired-OR connection of multiple 5962-8687504XA devices for system-level arbitration without logic-level conflicts. |
| Port-to-port interrupt signaling | Reduces software polling overhead by generating hardware interrupts on memory-mapped event triggers between processors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C131-25JC | Commercial-grade 1K×8 dual-port, 25ns access, 0°C to +70°C only; no MIL-PRF-38535 qualification. | Lacks radiation tolerance and extended temperature support; unsuitable for flight hardware. | Select only for ground-test benches or non-certified subsystems where cost outweighs environmental robustness. |
| AS7C31026B-25JC | 2K×16 organization, 25ns, 3.3V core; requires level-shifting for 5V TTL interfaces. | Higher density but incompatible voltage and bus width; necessitates PCB redesign and logic adaptation. | Consider for new designs targeting lower power and higher capacity, provided system architecture accommodates 3.3V I/O and 16-bit alignment. |
Compared with CY7C131-25JC and AS7C31026B-25JC, the 5962-8687504XA delivers guaranteed military temperature operation, QML certification, and native 5V TTL compatibility - making it irreplaceable in deployed aerospace platforms where reliability and qualification supersede cost or density.

FAQ
What is the maximum guaranteed access time for the 5962-8687504XA?
The 5962-8687504XA has a maximum guaranteed access time of 25ns for military-grade operation, verified across the full -55°C to +125°C temperature range and 4.5V–5.5V supply voltage. This value applies to both tAA (address access) and tACE (chip enable access) parameters per MIL-PRF-38535 test protocols and is production-tested on every lot.
Does the 5962-8687504XA support battery backup data retention?
No, the 5962-8687504XA does not support battery backup data retention. It is an SA (standard active) variant, not LA (low-power active). Only IDT7130LA/7140LA versions specify 2V data retention; the 5962-8687504XA is rated for full 5V operation only and lacks the internal circuitry for sub-3V retention mode.
How is port arbitration implemented in the 5962-8687504XA?
The 5962-8687504XA implements hardware port arbitration using dedicated BUSYL/BUSYR open-drain outputs. When both ports attempt access to the same memory location, the device asserts the BUSY signal on the losing port after tAPS (5ns arbitration priority setup time), blocking writes until the winning port completes its cycle - all without external logic.
Can the 5962-8687504XA be used as a SLAVE device with another 5962-8687504XA?
No, the 5962-8687504XA is exclusively a MASTER device. It contains on-chip arbitration logic and BUSY outputs, whereas SLAVE functionality (BUSY inputs, no arbitration logic) is implemented only in IDT7140-series parts. Two 5962-8687504XA units cannot operate in MASTER/SLAVE configuration.
What package type is used for the 5962-8687504XA?
The 5962-8687504XA is supplied in a 48-pin ceramic flatpack (FP48) per MIL-STD-1835, with dimensions of approximately 0.75 in × 0.75 in × 0.11 in. This hermetically sealed package meets MIL-PRF-38535 mechanical and environmental requirements for high-reliability military applications.
