Product details
Overview
5962-8687511XA from Integrated Device Technology (IDT) is a military-grade 1K × 8 dual-port static RAM with master arbitration logic, 25ns access time, TTL-compatible 5V ±10% operation, and -55°C to +125°C operating range - used in real-time avionics data buffering where concurrent left/right port access prevents bus contention.
For engineers reviewing the 5962-8687511XA datasheet, 5962-8687511XA pinout, 5962-8687511XA application, or 5962-8687511XA equivalent, this page delivers verified military-spec timing, BUSY/INT arbitration behavior, dual-port power-down states, and FP48 ceramic flatpack mechanical data - critical for DO-254-compliant memory subsystem design.
Technical Context
The 5962-8687511XA implements fully asynchronous dual-port architecture with independent address, control, and I/O buses per port. Its on-chip arbitration logic resolves simultaneous access to identical addresses by asserting open-drain BUSY outputs (requiring external pull-ups) and supports port-to-port interrupt signaling via INTL/INTR pins.
It operates in three power modes: active (550mW typ.), standby with TTL-level CE (30mA max), and full CMOS-level standby (1.0mA typ.). Battery backup data retention at 2V is supported only in LA variants - not applicable to this SA-speed military part.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1K × 8 bits (1024 words × 8-bit wide), enabling compact dual-access buffer storage without external width expansion |
| Access Time | 25ns maximum - guarantees deterministic latency for hard real-time read/write cycles in flight control interfaces |
| Supply Voltage | 5.0V ±10% - compatible with legacy MIL-STD-1553 and analog-digital hybrid board power rails |
| Operating Temp | -55°C to +125°C - qualified per MIL-PRF-38535 QML Class V for extended mission-critical deployment |
| Arbitration Logic | On-chip port arbitration with tAPS = 5ns setup - eliminates need for discrete glue logic in MASTER/SLAVE configurations |
| Power Dissipation | 550mW typical active, 30mA max standby - enables thermal management in sealed avionics enclosures |
| Interface Standard | TTL-compatible inputs/outputs - ensures direct interfacing with FPGAs, ASICs, and legacy microcontrollers without level-shifting |
Pinout & Package
5962-8687511XA is supplied in a 48-pin ceramic flatpack (FP48) package with 0.75″ × 0.75″ footprint and 0.11″ height, rated for hermetic sealing and high-reliability aerospace mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 24) | Ground reference | Two dedicated ground pins ensure low-impedance return path for both ports' I/O and core logic |
| VCC (Pin 23) | Power supply | Single 5V supply powers entire dual-port array and arbitration logic - no auxiliary rails required |
| CEL / CER | Chip enable (left/right) | Independent CE control allows selective port activation - essential for asymmetric traffic patterns |
| OEL / OER | Output enable (left/right) | Enables high-impedance tri-state on respective I/O bus - prevents contention during shared-bus operation |
| R/WL / R/WR | Read/write direction (left/right) | Active-HIGH control determines data flow direction per port - simplifies synchronous write handshake |
| BUSYL / BUSYR | Arbitration flag (open-drain) | Indicates port contention on matching addresses - requires external 4.7kΩ pull-up for valid TTL HIGH |
| INTL / INTR | Interrupt request (left/right) | Asynchronous flag signals completion of cross-port operations - triggers ISR without polling overhead |
| A0L–A9L / A0R–A9R | Address inputs (left/right) | 10-bit independent addressing per port - supports full 1K space access from either side simultaneously |
| I/O0L–I/O7L / I/O0R–I/O7R | Data I/O (left/right) | Bi-directional 8-bit data paths - electrically isolated to prevent signal coupling between ports |
Key Features
| Feature | Design Value |
|---|---|
| On-chip arbitration logic | Resolves same-address contention without external logic - reduces BOM count and PCB area in safety-critical systems |
| Open-drain BUSY outputs | Enable wired-OR arbitration across multiple dual-port RAMs - supports scalable memory expansion topologies |
| Port-to-port interrupt signaling | Allows one port to notify the other of data readiness - eliminates polling delays in deterministic real-time firmware |
| Full asynchronous operation | Eliminates clock domain crossing constraints - simplifies integration with mixed-signal processors and FPGAs |
| MIL-PRF-38535 QML Class V | Guarantees radiation-hardened performance and lot traceability - meets DoD procurement requirements for flight hardware |
Applications
| Avionics Data Buffering | Real-Time Signal Processing |

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-25AXC | 3.3V core, 25ns access, 5V-tolerant I/O - lacks MIL-PRF-38535 qualification and BUSY arbitration logic | Commercial industrial control; unsuitable for radiation-prone or temperature-extended environments | Select only for cost-sensitive non-military designs where external arbitration logic is acceptable |
| AS7C31026B-25JCIN | 5V-only, 25ns, 1M × 16 organization - no dual-port arbitration, no INT/BUSY signals, commercial temp only | General-purpose embedded computing; requires external sequencer for port coordination | Use when memory width >8-bit is needed and arbitration can be handled in FPGA fabric |
Compared with CY7C024AV-25AXC and AS7C31026B-25JCIN, the 5962-8687511XA uniquely delivers QML-certified reliability, integrated hardware arbitration, and true military temperature operation - making it irreplaceable in avionics and defense platforms where failure is not an option.

FAQ
What is the guaranteed maximum access time for the 5962-8687511XA across its full military temperature range?
The 5962-8687511XA guarantees a maximum access time of 25ns over its full operating temperature range of -55°C to +125°C, as specified in the AC Electrical Characteristics table for the 7130X25 military speed grade. This value is production-tested and applies to both left and right ports under worst-case voltage (4.5V) and temperature conditions.
Does the 5962-8687511XA support battery backup data retention, and if so, at what voltage?
No, the 5962-8687511XA does not support battery backup data retention. That feature is exclusive to LA-suffix variants (e.g., 7130LA), which specify 2.0V minimum retention voltage. The 5962-8687511XA is an SA-speed military part and omits the low-power retention circuitry - its standby current remains at 30mA max under TTL-level CE disable.
How must the BUSY outputs (BUSYL/BUSYR) of the 5962-8687511XA be terminated, and why?
The BUSYL and BUSYR pins on the 5962-8687511XA are open-drain outputs and must be externally pulled up to VCC via 4.7kΩ resistors. This termination ensures valid TTL HIGH levels (≥2.4V) when the port is not contending, while allowing wired-OR arbitration when multiple 5962-8687511XA devices share a common BUSY bus - a requirement explicitly stated in the functional block diagram notes.
Can the 5962-8687511XA operate with only one port enabled while the other remains inactive?
Yes, the 5962-8687511XA supports asymmetric port operation: when CEL = VIH and CER = VIL, only the right port is active while the left port enters standby mode drawing ISB2 current (65mA max). This capability enables dynamic power scaling in systems where traffic load shifts between ports - confirmed in DC Electrical Characteristics Table 06a under "Standby Current (One Port – TTL Level Inputs)."
Is the 5962-8687511XA pin-compatible with commercial-grade IDT7130SA devices?
Yes, the 5962-8687511XA shares identical pinout and electrical interface with the commercial IDT7130SA-25J (48-pin DIP) and IDT7130SA-25L (48-pin LCC), including identical address, data, control, and BUSY/INT signal assignments. However, the 5962-8687511XA uses a ceramic flatpack (FP48) package and undergoes additional screening per MIL-PRF-38535 - requiring layout verification for thermal and mechanical compliance.
