Product details
Overview
5962-8687504YA from IDT is a military-grade 1K × 8 dual-port static RAM with on-chip arbitration logic, 25ns/35ns access time (max), TTL-compatible 5V ±10% operation, and -55°C to +125°C operating range. It functions as a MASTER device with open-drain BUSY outputs and INT flag for port-to-port communication in real-time embedded systems requiring concurrent read/write access.
For engineers reviewing the 5962-8687504YA datasheet, 5962-8687504YA pinout, 5962-8687504YA application, or 5962-8687504YA equivalent, key selection criteria include BUSY arbitration timing (tBAA ≤ 35ns), dual-port standby current (ISB1 ≤ 30mA), MIL-PRF-38535 QML compliance, and FP48 ceramic flatpack mechanical compatibility.
Technical Context
The 5962-8687504YA implements fully asynchronous dual-port architecture with independent left/right address, control, and I/O buses. Its on-chip arbitration logic resolves contention via address-match detection and priority setup time (tAPS = 5ns), asserting BUSYL/BUSYR to inhibit writes during simultaneous access to identical memory locations.
It supports R/W-controlled and CE-controlled write cycles with defined tWP (25ns min), tWC (25ns min), and tBDD (≤35ns) for port-to-port data visibility. The device uses CMOS process technology and features battery-backed data retention (2V, LA variant), though 5962-8687504YA is SA-grade and does not support retention mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1K × 8 bits (1024 words × 8-bit wide); enables compact buffer storage without external width expansion |
| Access Time | 25ns max (military grade); guarantees deterministic latency for hard real-time interrupt handlers and DMA engines |
| Supply Voltage | 5.0V ±10%; compatible with legacy 5V TTL logic families without level-shifting circuitry |
| Operating Temp | -55°C to +125°C; qualified for aerospace, defense, and downhole industrial environments |
| Arbitration Logic | On-chip port arbitration with tAPS = 5ns setup; eliminates need for external glue logic in dual-CPU systems |
| BUSY Interface | Open-drain BUSYL/BUSYR outputs (requires external pull-up); provides hardware flow control for write collision avoidance |

Pinout & Package
5962-8687504YA 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 |
|---|---|---|
| GND (Pins 1, 24) | Ground reference | Two dedicated ground pins reduce ground bounce during high-speed dual-port transitions |
| VCC (Pin 25) | Power supply | Single 5V supply pin; all VCC pins must be connected per datasheet note |
| CEL / CER | Chip enable (left/right) | Independent chip select per port enables selective power-down of unused interface |
| OEL / OER | Output enable (left/right) | Controls tri-state of I/O bus; allows shared data bus usage between ports |
| R/WL / R/WR | Read/write direction (left/right) | Active-high read, active-low write; supports standard SRAM timing protocols |
| BUSYL / BUSYR | Arbitration status (open-drain) | Indicates port contention; requires external pull-up resistor per datasheet Note 1 |
| INTL / INTR | Interrupt flag (open-drain) | Signals inter-port event (e.g., address 3FF write); enables synchronous cross-port signaling |
| A0L–A9L / A0R–A9R | Address inputs (left/right) | 10-bit address buses decode full 1K space independently per port |
| I/O0L–I/O7L / I/O0R–I/O7R | Data I/O (bidirectional) | Separate 8-bit data paths eliminate bus turnaround delay in full-duplex operation |

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; no built-in arbitration logic; requires external BUSY management | Targeted at commercial/industrial systems with 3.3V infrastructure; lacks MIL qualification and open-drain BUSY outputs | Select when migrating to lower-voltage design and external arbitration logic is acceptable |
| AS7C31025B-25JIN | 5V-only, 25ns access, no arbitration logic; 32-pin SOJ package; higher standby current (ISB1 = 50mA) | Cost-optimized for non-military applications; no BUSY/INT flags or port-to-port signaling capability | Select for price-sensitive, single-CPU buffer applications where arbitration is handled in firmware |
Compared with CY7C024AV-25AXC and AS7C31025B-25JIN, the 5962-8687504YA uniquely delivers integrated arbitration, MIL-PRF-38535 qualification, and open-drain BUSY/INT in a 48-pin FP48 package-enabling drop-in replacement only in legacy 5V military designs requiring hardware-enforced concurrency control.

FAQ
What is the maximum access time specification for the 5962-8687504YA?
The 5962-8687504YA has a maximum access time of 25ns for military-grade operation, verified across the full -55°C to +125°C temperature range and 5.0V ±10% supply voltage. This value applies to both tAA (address access) and tACE (chip enable access) parameters per the official IDT datasheet revision Jul.12.21, and is guaranteed under MIL-PRF-38535 QML Class V testing.
Does the 5962-8687504YA support battery backup data retention?
No, the 5962-8687504YA is an SA-grade device and does not support battery backup data retention. Only LA-grade variants (e.g., 5962-8687504LA) provide 2V data retention capability. The 5962-8687504YA is optimized for high-speed operation and full-temperature-range reliability, not low-power retention mode.
What package type is used for the 5962-8687504YA?
The 5962-8687504YA is packaged in a 48-pin ceramic flatpack (FP48), with dimensions approximately 0.75 in × 0.75 in × 0.11 in. This hermetically sealed package meets MIL-STD-1835 and is qualified for high-reliability military and aerospace applications requiring moisture resistance and thermal stability.
How does the BUSY arbitration logic function in the 5962-8687504YA?
The 5962-8687504YA implements on-chip arbitration that asserts BUSYL or BUSYR when both ports attempt access to the same memory address. It uses address-match detection and a 5ns priority setup time (tAPS) to determine which port wins. As a MASTER device, its BUSY outputs are open-drain and require external pull-up resistors per datasheet Note 1.
Is the 5962-8687504YA pin-compatible with the IDT7140 SLAVE dual-port SRAM?
No, the 5962-8687504YA is a MASTER device (functionally equivalent to IDT7130) and is not pin-compatible with the SLAVE IDT7140. While both share the same FP48 footprint and basic signal names, their BUSY and INT pin behaviors differ fundamentally: 5962-8687504YA drives BUSY as output, whereas IDT7140 receives BUSY as input. Direct substitution would cause functional failure.
