Product details
Overview
5962-8687501XA from IDT is a military-grade 1K × 8 dual-port static RAM with master arbitration logic, 25ns access time (max), 5V ±10% supply, and -55°C to +125°C operation - used in real-time avionics data buffers where concurrent left/right port access prevents bus contention.
For engineers reviewing the 5962-8687501XA datasheet, 5962-8687501XA pinout, 5962-8687501XA application, or 5962-8687501XA equivalent, this page delivers verified timing parameters, BUSY/INT arbitration behavior, MIL-PRF-38535 QML compliance, and exact flatpack pin mapping - critical for DO-254 safety-critical memory subsystems.
Technical Context
The 5962-8687501XA implements fully asynchronous dual-port architecture with independent address/control/I/O on left and right ports. Its on-chip arbitration logic resolves simultaneous access to identical addresses by asserting BUSYL/BUSYR outputs (open-drain, pull-up required) within 20ns (tBAA/tBAC), enforcing write inhibition on the contending port.
It supports port-to-port interrupt signaling via INTL/INTR pins with 25ns interrupt set/reset timing (tINS/tINR), and enables battery-backed data retention at 2V (LA variant only) - though 5962-8687501XA is SA-rated and excludes retention mode per MIL-PRF-38535 Class V requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1,024 × 8 bits - provides byte-wide dual-access buffer for 16-bit data paths when paired with IDT7140 slave. |
| Access Time | 25 ns max - guarantees deterministic read latency for hard real-time systems operating at ≤40 MHz clock domains. |
| Supply Voltage | 4.5 V to 5.5 V - compatible with legacy 5V TTL/CMOS logic without level-shifting in MIL-STD-1553 or ARINC 429 interfaces. |
| Operating Temp | -55°C to +125°C - qualified per MIL-PRF-38535 QML Class V for missile guidance and radar signal processing. |
| Power (Active) | 110 mA typ (ICC) - enables low-thermal-profile integration into conduction-cooled avionics chassis. |
| Power (Standby) | 25 mA max (ISB1, TTL inputs) - reduces quiescent load during processor sleep cycles in mission-critical standby modes. |
| BUSY Timing | tBAA = 20 ns max - ensures arbitration response fast enough to prevent metastability in <100 ns contention windows. |
Pinout & Package
5962-8687501XA is supplied in a 48-pin ceramic flatpack (FP48) package measuring 0.75″ × 0.75″ × 0.11″, compliant with MIL-STD-883 method 2016. All VCC pins require local 0.1 µF decoupling; all GND pins must be connected to system ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 24, 25, 48) | Ground reference | Four dedicated ground pins minimize ground bounce during simultaneous dual-port transitions. |
| VCC (Pins 23, 26) | Power supply | Dual VCC pins reduce IR drop and support high-current transient demands of concurrent reads/writes. |
| CEL / CER | Chip enable (left/right) | Independent CE control allows selective port power-down - essential for deterministic low-power sequencing. |
| OEL / OER | Output enable (left/right) | Asynchronous OE per port enables glitch-free bus sharing with multiple masters in time-triggered architectures. |
| R/WL / R/WR | Read/write direction (left/right) | Separate R/W lines eliminate direction-control timing constraints - simplifies FPGA interface logic. |
| BUSYL / BUSYR | Arbitration flag (open-drain) | Requires external pull-up; asserts LOW to block writes during address contention - prevents corrupted memory updates. |
| INTL / INTR | Interrupt request (open-drain) | Signals cross-port events (e.g., data ready); requires pull-up and edge-triggered ISR handling in host processor. |
| A0L–A9L / A0R–A9R | Address inputs (left/right) | 10-bit addressing per port - maps directly to 1K memory space without external address decoding logic. |
| I/O0L–I/O7L / I/O0R–I/O7R | Data I/O (bidirectional, left/right) | True bidirectional I/O per port eliminates need for external transceivers in full-duplex memory-mapped I/O designs. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip arbitration logic | Resolves same-address contention without external logic - eliminates race conditions in dual-CPU systems. |
| Open-drain BUSY/INT outputs | Enables wired-OR interrupt aggregation across multiple dual-port RAMs on shared interrupt lines. |
| Full asynchronous operation | Permits independent clock domains on left/right ports - critical for heterogeneous SoC interconnects. |
| TTL-compatible I/O | Direct interface to legacy FPGAs, ASICs, and microcontrollers without voltage translation circuitry. |
| MIL-PRF-38535 QML Class V | Qualified for flight-critical applications with full lot traceability, radiation hardness assurance, and burn-in screening. |

FAQ
What is the maximum access time specification for the 5962-8687501XA?
The 5962-8687501XA has a maximum access time of 25 ns across its full military temperature range (-55°C to +125°C), verified per MIL-PRF-38535 QML Class V testing. This value applies to both tAA (address access) and tACE (chip enable access) under VCC = 5.0 V ±10%, and is guaranteed for all units in the lot - not just sample characterization.
Does the 5962-8687501XA support battery backup data retention?
No, the 5962-8687501XA is an SA (standard power) variant and does not support battery backup data retention. Only LA variants (e.g., 5962-8687502XA) provide 2V data retention capability. The 5962-8687501XA is optimized for high-speed deterministic operation, not low-voltage hold modes.
How is BUSY arbitration implemented on the 5962-8687501XA?
The 5962-8687501XA implements hardware arbitration via open-drain BUSYL and BUSYR outputs. When both ports attempt access to the same address, the device asserts the relevant BUSY line LOW within 20 ns (tBAA), forcing the contending port to inhibit writes. External pull-up resistors (typically 4.7 kΩ) are mandatory for proper open-drain operation.
What package type is used for the 5962-8687501XA?
The 5962-8687501XA is packaged in a 48-pin ceramic flatpack (FP48) per MIL-STD-1835, with dimensions of 0.75 in × 0.75 in × 0.11 in. This hermetically sealed package meets MIL-STD-883 requirements for moisture resistance and thermal cycling endurance in aerospace deployments.
Can the 5962-8687501XA be used as a standalone memory or only with a slave device?
The 5962-8687501XA functions as a standalone 1K × 8 dual-port SRAM. It also serves as the MASTER in MASTER/SLAVE configurations with IDT7140-series slaves (e.g., 5962-8767701XA) to construct 16-bit-or-wider memory systems without external glue logic - preserving full-speed operation and error-free data integrity.
