Product details
Overview
5962-8687507UA 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 systems for real-time interprocessor communication in avionics and radar signal processing.
For engineers reviewing the 5962-8687507UA datasheet, 5962-8687507UA pinout, 5962-8687507UA application, or 5962-8687507UA equivalent, key selection criteria include BUSY-flag arbitration timing (tBAA ≤ 35ns), INT flag port-to-port signaling, dual independent asynchronous ports, and MIL-PRF-38535 QML Class V compliance for high-reliability embedded systems.
Technical Context
The 5962-8687507UA implements fully asynchronous dual-port architecture with separate address, control, and I/O buses for left and right ports. Its on-chip arbitration logic resolves simultaneous access contention via BUSY output assertion and priority set-up time (tAPS = 5ns).
It supports R/W-controlled and CE-controlled write cycles, features open-drain BUSY outputs requiring external pull-ups, and provides INT/INTR flags for inter-port interrupt generation-enabling deterministic data exchange without external logic in real-time control subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1,024 × 8 bits - supports byte-wide parallel data exchange between two independent processors or bus masters. |
| Access Time | 35ns max (MIL grade) - enables synchronization with 28.6 MHz bus clocks in real-time radar front-end buffers. |
| Operating Voltage | 5.0V ±10% - compatible with legacy TTL and 5V CMOS logic families without level-shifting. |
| Temperature Range | -55°C to +125°C - qualified per MIL-PRF-38535 QML Class V for airborne and spaceborne mission-critical systems. |
| Standby Current | ≤65mA (ISB1, TTL inputs) - allows low-power hold mode during processor idle states in power-constrained platforms. |
| BUSY Arbitration | tBAA ≤ 35ns, tAPS = 5ns - guarantees deterministic resolution of port collisions within one clock cycle at 28 MHz. |
| Interrupt Latency | tINS ≤ 25ns - ensures sub-30ns notification of memory updates between co-located DSP and FPGA subsystems. |
Pinout & Package
5962-8687507UA is supplied in a 48-pin ceramic flatpack (FP48) package measuring approximately 0.75 in × 0.75 in × 0.11 in, compliant with MIL-STD-1835.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A9L | Left port address inputs | 10-bit address bus for left-side memory access; supports full 1K address space decoding. |
| I/O0L–I/O7L | Left port bidirectional data | 8-bit TTL-compatible data path; high-impedance when OEL = VIH or CEL = VIH. |
| CEL, OEL, R/WL | Left port controls | Chip Enable, Output Enable, Read/Write select - fully asynchronous operation with no clock required. |
| BUSYL, INTL | Left port open-drain flags | BUSYL signals write contention; INTL asserts on programmed address match (A9L–A0L = 3FEh/3FFh). |
| A0R–A9R | Right port address inputs | Independent 10-bit address bus; enables concurrent access to same memory array from second processor. |
| I/O0R–I/O7R | Right port bidirectional data | Electrically isolated 8-bit data path; no bus contention when ports operate asynchronously. |
| CER, OER, R/WR | Right port controls | Functionally identical to left-side controls; permits symmetrical dual-master interface design. |
| BUSYR, INTR | Right port open-drain flags | BUSYR blocks writes during left-port conflict; INTR enables hardware-triggered ISR entry on right-side CPU. |
| VCC, GND | Power supply | All VCC pins must be decoupled locally; all GND pins tied to common ground plane for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip arbitration logic | Eliminates need for external bus controllers or glue logic in dual-CPU architectures. |
| Open-drain BUSY outputs | Enables wired-OR connection of multiple 5962-8687507UA devices for scalable shared-memory clusters. |
| Port-to-port interrupt flags | Supports lock-free synchronization via address-matched INT/INTR assertion without polling overhead. |
| Asynchronous dual-port operation | Allows independent read/write cycles on each port with no clock domain crossing or FIFO buffering. |
| MIL-PRF-38535 QML Class V | Guarantees radiation hardness, burn-in screening, and lot traceability for defense/aerospace deployments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C131-55WI | 55ns access, commercial/industrial temp only (-40°C to +85°C), no MIL-PRF-38535 qualification | Not suitable for flight-critical or space environments; lacks QML screening and extended temperature validation | Select only for ground-test equipment or non-certified subsystems where cost outweighs reliability requirements. |
| IDT7132LA55J | Same 1K×8 architecture but SLAVE-only function; no on-chip arbitration logic or BUSY output | Requires external arbitration logic when paired with MASTER; cannot replace 5962-8687507UA standalone | Use only as companion SLAVE in expanded 16-bit+ systems; not a functional substitute for MASTER role. |
Compared with CY7C131-55WI and IDT7132LA55J, the 5962-8687507UA uniquely delivers MIL-qualified arbitration, deterministic BUSY timing, and full MASTER functionality in a single QML Class V package-enabling certified real-time interprocessor communication without external components.

FAQ
What is the maximum access time specification for the 5962-8687507UA?
The 5962-8687507UA has a maximum access time of 35ns for both address access (tAA) and chip enable access (tACE) under military temperature conditions (-55°C to +125°C) and 5.0V ±10% supply. This value is production-tested and guaranteed per MIL-PRF-38535 QML Class V requirements, ensuring deterministic timing in hard real-time avionics applications.
Does the 5962-8687507UA require external pull-up resistors on BUSY pins?
Yes, the 5962-8687507UA's BUSYL and BUSYR pins are open-drain outputs and require external pull-up resistors to VCC. The datasheet specifies a 1.25kΩ resistor for standard 5V operation with 100pF load, ensuring valid HIGH levels during arbitration and preventing floating states that could cause spurious write inhibition in safety-critical systems.
Can the 5962-8687507UA operate as a standalone memory without a SLAVE device?
Yes, the 5962-8687507UA functions as a complete stand-alone 1K × 8 dual-port SRAM. Its on-chip arbitration logic, BUSY flag generation, and INT/INTR signaling are fully operational without pairing. The SLAVE capability (e.g., IDT7140) is optional and used only when expanding to 16-bit or wider data paths-no external components are needed for basic dual-processor shared memory.
What is the purpose of the INTL and INTR pins on the 5962-8687507UA?
The INTL and INTR pins provide hardware-generated interrupts for port-to-port event notification. Writing to specific addresses (e.g., A9L–A0L = 3FEh sets INTL; A9R–A0R = 3FFh sets INTR) asserts the corresponding flag, enabling zero-latency, polling-free synchronization between processors. This eliminates software overhead in time-critical loops such as radar pulse processing or flight control servo updates.
Is the 5962-8687507UA compatible with modern 3.3V systems?
No, the 5962-8687507UA is strictly a 5V TTL-compatible device with VIH minimum of 2.2V and VIL maximum of 0.8V. It requires a 5.0V ±10% supply and is not 3.3V tolerant. Interfacing with 3.3V processors necessitates level-shifting circuitry on all address, data, and control lines to prevent damage and ensure logic-level compatibility.
