Product details
Overview
5962-8687505XA from Integrated Device Technology (IDT) is a military-grade 1K × 8 dual-port static RAM with independent left/right asynchronous ports, 25ns max access time, on-chip arbitration logic, and BUSY/INT flags for inter-port coordination-used in real-time avionics data buffering and radar signal processing systems.
For engineers reviewing the 5962-8687505XA datasheet, 5962-8687505XA pinout, 5962-8687505XA application, or 5962-8687505XA equivalent, this page delivers verified military-spec timing parameters, dual-port arbitration behavior, MIL-PRF-38535 QML compliance status, and exact FP48 ceramic flatpack mechanical and electrical interface details.
Technical Context
The 5962-8687505XA implements fully asynchronous dual-port operation with separate address, control, and I/O buses per port. It integrates on-chip arbitration logic to resolve simultaneous access contention via BUSY flag assertion and supports port-to-port interrupt signaling using INTL/INTR pins.
It operates at 5.0V ±10% over –55°C to +125°C, meets MIL-PRF-38535 Class V QML requirements, and features open-drain BUSY outputs requiring external pull-up resistors-critical for deterministic bus arbitration in safety-critical embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 1K × 8 bits (1024 words × 8-bit wide), dual-port architecture enabling concurrent read/write on left and right ports |
| Access Time (max) | 25 ns - guarantees deterministic latency for real-time interrupt-driven memory access in flight control computers |
| Operating Voltage | 5.0 V ±10% - compatible with legacy 5V TTL logic families without level-shifting circuitry |
| Temperature Range | –55°C to +125°C - qualified for airborne and spaceborne platforms per MIL-PRF-38535 Class V |
| Package | 48-pin ceramic flatpack (FP48) - hermetically sealed, low-inductance, high-reliability package for harsh-environment deployment |
| Arbitration Logic | On-chip port arbitration with BUSYL/BUSYR open-drain outputs - resolves address-match contention without external glue logic |
| Interrupt Support | Dedicated INTL and INTR pins - enables hardware-triggered cross-port event notification for synchronized data exchange |
Pinout & Package
48-pin ceramic flatpack (FP48), top view, body size ≈ 0.75 in × 0.75 in × 0.11 in. All VCC pins require connection to +5V supply; all GND pins must be tied to system ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 24, 25, 48) | Ground reference | Four dedicated ground pins minimize ground bounce during simultaneous port switching |
| VCC (Pins 23, 26) | Power supply | Dual VCC pins reduce IR drop and improve noise immunity across high-speed dual-port operation |
| CEL / CER | Chip enable (left/right) | Independent chip select per port enables selective power-down of unused port to reduce standby current |
| OEL / OER | Output enable (left/right) | Controls tri-state output drivers; high-Z when deasserted to prevent bus contention |
| R/WL / R/WR | Read/write direction (left/right) | Active-high write control; determines data flow direction on respective I/O bus |
| BUSYL / BUSYR | Arbitration status (open-drain) | Asserted low when opposite port accesses same address-requires external pull-up for proper logic level |
| INTL / INTR | Interrupt request (left/right) | Asynchronous flag indicating port-initiated interrupt; cleared by reading specific address (e.g., 3FEH/3FFH) |
| A0L–A9L / A0R–A9R | Address inputs (left/right) | 10-bit address buses support full 1K-word addressing independently per port |
| I/O0L–I/O7L / I/O0R–I/O7R | Data I/O (bidirectional, left/right) | Separate 8-bit data paths eliminate multiplexing overhead and maximize throughput |
Key Features
| Feature | Design Value |
|---|---|
| On-chip arbitration logic | Eliminates need for external priority encoder or discrete logic in MASTER/SLAVE memory expansion configurations |
| Open-drain BUSY outputs | Enables wired-OR arbitration bus sharing across multiple dual-port devices in distributed memory subsystems |
| Port-to-port interrupt signaling | Hardware-synchronized event notification avoids polling delays and reduces CPU overhead in real-time OS environments |
| MIL-PRF-38535 QML Class V compliance | Guarantees radiation hardness, burn-in screening, and lot traceability required for DoD and NASA programs |
| 25ns military-grade access time | Meets deterministic timing budgets for pulse-Doppler radar frame buffering and digital signal processor co-processing |
Applications
| Avionics Data Buffering | Radar Signal Processing |
|---|---|

Use Value: Maintains integrity of guidance constants during high-G launch transients and sustained vibration per MIL-STD-810G. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8767201XA | Same FP48 package and MIL-PRF-38535 Class V qualification, but 35ns access time and no on-chip arbitration logic | Lacks BUSY/INT signaling; requires external arbitration circuitry for multi-port coordination | Select only when deterministic 25ns latency is not required and system-level arbitration is already implemented |
| 5962-9201201XA | 5V 1K×8 dual-port SRAM in 48-pin DIP; MIL-PRF-38535 Class V qualified but rated for 55ns access time | Slower timing and through-hole packaging limit use in high-density, high-vibration PCB layouts | Consider for legacy board refresh where footprint compatibility and lower cost outweigh speed requirements |
Compared with 5962-8687505XA, the 5962-8767201XA trades arbitration capability for marginally lower power in standby, while the 5962-9201201XA sacrifices speed and package robustness for broader legacy compatibility-neither offers identical 25ns deterministic arbitration performance in hermetic flatpack form.

FAQ
What is the guaranteed maximum access time for 5962-8687505XA across its full military temperature range?
The 5962-8687505XA is specified for a maximum access time of 25 ns over its full operating temperature range of –55°C to +125°C, as confirmed in the AC Electrical Characteristics table (2689 tbl 09a) under the "7130X25" column for military grade. This value applies to both tAA (address access) and tACE (chip enable access) timing parameters and is production-tested per MIL-PRF-38535 requirements.
Does 5962-8687505XA include on-chip arbitration logic, and how is it implemented?
Yes, 5962-8687505XA includes on-chip arbitration logic exclusive to the IDT7130 master device. It asserts BUSYL or BUSYR low when both ports attempt access to the same memory location, using address-match detection and tAPS (arbitration priority setup time) of 5 ns. The BUSY outputs are open-drain and require external pull-up resistors, as explicitly noted in Functional Block Diagram Notes 1 and 2.
What package type and mechanical dimensions does 5962-8687505XA use?
5962-8687505XA is packaged in a 48-pin ceramic flatpack (FP48) with body dimensions approximately 0.75 in × 0.75 in × 0.11 in, as documented in Pin Configuration Note 3. This hermetically sealed package meets MIL-STD-883 requirements for moisture resistance and thermal cycling reliability in aerospace deployments.
How does the interrupt functionality work on 5962-8687505XA, and what addresses trigger it?
5962-8687505XA supports hardware interrupts via INTL and INTR pins. Writing to address 3FEH sets the opposite port's interrupt flag; writing to 3FFH clears it-per Truth Table II (2689 tbl 14). Interrupt timing is characterized with tINS ≤ 25 ns and tINR ≤ 25 ns for the 25ns speed grade, enabling sub-microsecond event signaling between co-located processors.
Is battery backup or data retention supported on 5962-8687505XA?
No, 5962-8687505XA does not support battery backup or low-voltage data retention. That feature is exclusive to LA-suffix variants (e.g., IDT7130LA), which specify VDR = 2.0 V and ICCDR ≤ 4000 µA. The 5962-8687505XA is an SA-suffix military-grade part with standard 5V-only operation and no data retention mode-confirmed by omission of retention parameters in its DC/AC tables.
