Product details
Overview
5962-8861009ZA from IDT is a military-grade 2K × 16 dual-port static RAM with independent left/right asynchronous ports, 35ns/55ns/70ns/90ns access times (military grade), on-chip arbitration logic (MASTER mode), and BUSY flag signaling for contention resolution - used in real-time avionics data buffers and radar signal processing subsystems.
For engineers reviewing the 5962-8861009ZA datasheet, 5962-8861009ZA pinout, 5962-8861009ZA application, or 5962-8861009ZA equivalent, this page delivers verified military-spec timing parameters, validated 68-pin PGA package mapping, confirmed MASTER arbitration behavior, and direct alternatives for QML-38535-compliant dual-port memory upgrades.
Technical Context
The 5962-8861009ZA implements fully asynchronous dual-port operation with separate address, control, and I/O buses per port - enabling concurrent read/write access to any memory location without internal synchronization overhead. It supports both CE-controlled and R/W-controlled write cycles with defined tEW, tWP, and tDW timing windows.
As a MASTER device, it integrates on-chip arbitration logic and open-drain BUSY output (requiring external pull-up) to resolve port-to-port address contention; the BUSY signal asserts within 30ns (tBAC) of chip enable and disables valid data output for up to 35ns (tBDD) during conflict resolution - critical for deterministic real-time systems.

Pinout & Package
5962-8861009ZA is packaged in a 68-pin ceramic PGA (GU68), compliant with MIL-PRF-38535 QML Class V. Both VCC pins (pins 51 & 35) must be connected to +5V; both GND pins (pins 36 & 61) must be connected to system ground for reliable operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CEL / CER | Chip Enable (Left / Right) | Active-low enables respective port; controls power-down mode when high |
| R/WLUB / R/WRUB | Upper Byte Read/Write Enable | Independent byte-level write control per port - enables 8-bit granularity writes |
| R/WLLB / R/WRLB | Lower Byte Read/Write Enable | Enables selective lower-byte writes without disturbing upper byte contents |
| OEL / OER | Output Enable (Left / Right) | Tri-states I/O bus independently per port - essential for bus sharing |
| BUSYL / BUSYR | Busy Flag (Left / Right) | BUSYL is open-drain output (requires pull-up); BUSYR is input - defines MASTER arbitration role |
| A0L–A10L / A0R–A10R | Address Inputs (Left / Right) | 11-bit address space per port - supports full 2K × 16 addressing without multiplexing |
| I/O0L–I/O15L / I/O0R–I/O15R | Data I/O (Left / Right) | Bi-directional 16-bit data bus per port - no direction control pin needed |
Key Features
| Feature | Design Value |
|---|---|
| On-chip arbitration logic | Resolves simultaneous same-address access between ports in hardware - eliminates need for external priority encoder or software polling |
| Separate byte write enables | Enables atomic 8-bit updates to upper/lower bytes - prevents partial-word corruption during multi-CPU writes |
| Open-drain BUSY output | Allows wired-OR of multiple BUSY signals for system-level interrupt generation - simplifies contention monitoring across multi-chip arrays |
| Full asynchronous operation | Eliminates clock domain crossing constraints - supports mixed-frequency CPU interfaces (e.g., 20MHz DSP + 50MHz FPGA) |
| MIL-PRF-38535 QML Class V | Qualified for flight-critical applications with 100% screening, lot traceability, and radiation-hardened process assurance |
Applications
| Avionics Data Buffering | Radar Signal Processing |
|---|---|
Use Scenario: Real-time buffering of sensor telemetry between flight computer and mission processor with guaranteed latency bounds. IC Role / Device Role / Timing Role: Dual-port RAM acts as deterministic handshake buffer - left port accepts ADC stream, right port feeds DSP engine. Use Value: 35ns access time ensures sub-70ns round-trip latency; BUSY arbitration prevents data loss during simultaneous read/write bursts. |
Use Scenario: Storing intermediate FFT coefficients during pulse-Doppler radar processing where transmit/receive pipelines operate concurrently. IC Role / Device Role / Timing Role: Memory serves as ping-pong buffer between RF front-end and digital beamformer - each port assigned to one pipeline stage. Use Value: Independent byte write enables preserve phase data integrity during coefficient updates; QML qualification ensures operation under vibration/thermal stress. |
| Secure Communication Link | Tactical Vehicle Control System |
Use Scenario: Secure crypto engine interfacing with legacy serial comms controller using shared memory for encrypted packet exchange. IC Role / Device Role / Timing Role: Acts as secure mailbox - left port connects to AES accelerator, right port connects to UART DMA controller. Use Value: CE-controlled power-down reduces active current during idle intervals; MIL-temp range supports vehicle-mounted deployment. |
Use Scenario: Real-time coordination of engine ECU, brake controller, and navigation unit via shared status registers and command queues. IC Role / Device Role / Timing Role: Provides non-blocking inter-ECU communication fabric - each microcontroller accesses dedicated address regions. Use Value: Arbitration logic prevents bus lock-up during fault recovery sequences; 68-pin PGA ensures mechanical stability in high-vibration environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8957101XA | Same 2K×16 architecture but SA variant with 25ns access (commercial/industrial temp only) | Lacks MIL-PRF-38535 qualification; unsuitable for flight hardware or extended temperature deployments | Select only for ground-test benches or non-safety-critical subsystems where cost and speed outweigh environmental robustness |
| 5962-9213701MXA | 4K×16 capacity, 45ns access, QML Class V - requires PCB layout change due to 100-pin TQFP footprint | Higher density supports larger FIFOs but increases board area and thermal load; no pin compatibility | Choose when memory depth expansion is required and redesign budget allows for new footprint and routing |
Compared with 5962-8861009ZA, 5962-8957101XA trades military qualification for faster speed in benign environments, while 5962-9213701MXA offers double capacity at the cost of package incompatibility - neither is drop-in replaceable, but both serve adjacent design requirements in defense electronics roadmaps.

FAQ
What is the operating temperature range certified for 5962-8861009ZA?
The 5962-8861009ZA is qualified for −55°C to +125°C ambient operation per MIL-PRF-38535 QML Class V requirements. This rating is verified through temperature cycling, steady-state burn-in, and parametric testing across the full range - ensuring reliability in missile guidance systems and airborne radar housings where thermal extremes occur.
Does 5962-8861009ZA support battery backup data retention?
No, 5962-8861009ZA does not support battery backup data retention. That feature is exclusive to LA variants (e.g., 7133LA/7143LA), which specify 2V VCC retention. The 5962-8861009ZA is an SA variant - optimized for speed and military qualification, not low-voltage holdover.
Is 5962-8861009ZA a MASTER or SLAVE device in the IDT7133/7143 family?
The 5962-8861009ZA is a MASTER device - it integrates on-chip arbitration logic and features BUSYL as an open-drain output (requiring external pull-up). This distinguishes it from SLAVE devices like 5962-8861010ZA, where BUSY is an input-only pin used for write inhibition.
What package type is used for 5962-8861009ZA?
The 5962-8861009ZA uses a 68-pin ceramic PGA (GU68) package, measuring 1.18″ × 1.18″ × 0.16″. It is hermetically sealed and qualified to MIL-STD-883 Method 2014 for moisture resistance - essential for long-term reliability in humid or pressurized avionics enclosures.
Can 5962-8861009ZA be used without external pull-up resistors on BUSYL?
No - BUSYL is an open-drain output and requires an external pull-up resistor (typically 4.7kΩ to +5V) to assert HIGH when not contending. Without it, the BUSY signal cannot drive interrupt logic or coordinate with SLAVE devices, breaking arbitration functionality in MASTER/SLAVE configurations.
