Product details
Overview
5962-8687511YA from Integrated Device Technology (IDT) is a military-grade 1K × 8 dual-port static RAM with on-chip arbitration logic, designed as a MASTER device for port-to-port contention management. It features 25ns/35ns access time, TTL-compatible 5V ±10% operation, and open-drain BUSY outputs requiring external pull-up resistors. Used in real-time avionics data buffers where simultaneous left/right port access must be resolved without external logic.
For engineers reviewing the 5962-8687511YA datasheet, 5962-8687511YA pinout, 5962-8687511YA application, or 5962-8687511YA equivalent, key selection criteria include BUSY arbitration timing (tBAA ≤ 20ns), dual-port write conflict resolution, MIL-PRF-38535 QML qualification, and compatibility with IDT7140 SLAVE devices in 16-bit memory expansion.
Technical Context
The 5962-8687511YA implements fully asynchronous dual-port architecture with independent left/right address, control, and I/O buses. Its on-chip arbitration logic detects address matches between ports and asserts BUSYL/BUSYR to inhibit conflicting writes - a hardware-enforced mutual exclusion mechanism.
As a MASTER device, it provides open-drain BUSY outputs (requiring external pull-ups) and INTL/INTR flags for inter-port signaling, while SLAVE devices like IDT7140 accept BUSY as inputs. The device supports battery backup data retention only in LA variants (not applicable to this SA-spec military part).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1,024 × 8 bits - provides 1KB of fast, non-volatile-accessible RAM per port |
| Access Time | 25ns max (military grade) - guarantees deterministic read latency for hard real-time systems |
| Supply Voltage | 5.0V ±10% - compatible with legacy 5V TTL logic families without level translation |
| Operating Temp | −55°C to +125°C - qualified for extended-range military environmental stress screening |
| Arbitration Logic | On-chip port-to-port address match detection - eliminates need for external bus grant controllers |
| BUSY Interface | Open-drain outputs (BUSYL/BUSYR) - requires external pull-up resistors for wired-OR contention signaling |
| Compliance | MIL-PRF-38535 QML Class V - certified for high-reliability defense/aerospace applications |
Pinout & Package
5962-8687511YA is supplied in a 48-pin ceramic flatpack (FP48) package measuring approximately 0.75″ × 0.75″ × 0.11″, compliant with MIL-STD-883 packaging requirements for hermeticity and thermal cycling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 24) | Ground reference | Two dedicated ground pins ensure low-impedance return paths for both ports' I/O and core logic |
| VCC (Pin 25) | Power supply | Single 5V supply powers entire dual-port array and arbitration logic; all VCC pins must be connected |
| CEL / CER | Chip enable (left/right) | Active-low enables independently activate each port's memory array and control logic |
| OEL / OER | Output enable (left/right) | Active-low controls tri-state output drivers; high-Z when disabled to prevent bus contention |
| R/WL / R/WR | Read/write control (left/right) | High = read, low = write; determines direction of data flow on respective I/O bus |
| BUSYL / BUSYR | Arbitration flag (left/right) | Open-drain outputs asserted low during address conflict; require external pull-up resistors |
| INTL / INTR | Interrupt flag (left/right) | Push-pull outputs signal inter-port events (e.g., flag set/clear via special address writes) |
| A0L–A9L / A0R–A9R | Address inputs (left/right) | 10-bit address buses select one of 1,024 locations per port; no internal address latching |
| I/O0L–I/O7L / I/O0R–I/O7R | Data I/O (left/right) | Bidirectional 8-bit data buses; driven by internal drivers during reads, high-Z during writes unless OE active |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C131-25VC | Commercial-grade 1K×8 dual-port; no MIL-PRF-38535 qualification; 25ns access but −40°C to +85°C only | Lacks radiation tolerance and extended temperature range; unsuitable for space or high-G environments | Select only for ground-based industrial systems where QML certification is not mandated |
| IDT7134SA25JGI | Same IDT family, 2K×8 capacity; identical 25ns timing and MIL-PRF-38535 Class V; 52-pin PLCC instead of 48-pin flatpack | Higher density but larger footprint; requires PCB redesign due to different pin count and layout | Choose when memory expansion beyond 1KB is needed without changing architecture or qualification level |
Compared with CY7C131-25VC and IDT7134SA25JGI, the 5962-8687511YA uniquely delivers QML Class V compliance in a compact 48-pin flatpack while maintaining strict 25ns arbitration timing - essential for retrofitting legacy military platforms with space-constrained layouts.

FAQ
What is the maximum guaranteed access time for 5962-8687511YA across its full military temperature range?
The 5962-8687511YA guarantees a maximum access time of 25ns over the full −55°C to +125°C operating range, as specified in the AC Electrical Characteristics table for the 7130X25 military-speed variant. This timing applies to both tAA (address access) and tACE (chip enable access) parameters under VCC = 5.0V ±10%, and is validated per MIL-PRF-38535 test requirements. The 5962-8687511YA does not support the 20ns commercial speed bin.
Does 5962-8687511YA support battery backup data retention?
No, the 5962-8687511YA does not support battery backup data retention. It is an SA (standard power) variant, not an LA (low-power) variant. Data retention capability at 2V is exclusive to LA versions such as 5962-8687501YA, as confirmed in the Data Retention Characteristics table which explicitly lists "LA Version Only". The 5962-8687511YA requires continuous 5V supply for memory retention.
How are BUSY signals implemented on 5962-8687511YA and what external components are required?
The 5962-8687511YA implements BUSYL and BUSYR as open-drain outputs, as stated in Note 1 of the Functional Block Diagram and Pin Configuration notes. Each requires an external pull-up resistor to VCC to establish a valid HIGH state when deasserted. Typical values range from 1kΩ to 4.7kΩ depending on bus capacitance and rise-time requirements. Without these resistors, BUSY signals cannot drive HIGH and arbitration will fail.
Can 5962-8687511YA be used as a SLAVE device in a MASTER/SLAVE configuration?
No, the 5962-8687511YA is exclusively a MASTER device. Its datasheet explicitly states that BUSY outputs are open-drain and that it contains on-chip arbitration logic - defining characteristics of the MASTER role. SLAVE functionality (BUSY as input, no arbitration logic) is implemented only in IDT7140-series parts. Attempting to use 5962-8687511YA as a SLAVE would result in incorrect BUSY behavior and potential system lockup.
What package type is used for 5962-8687511YA and is it hermetically sealed?
The 5962-8687511YA uses a 48-pin ceramic flatpack (FP48) package, as shown in the Pin Configuration diagram labeled "7130/40 FP48(4)". Per MIL-PRF-38535 requirements for QML Class V, this package is hermetically sealed using ceramic-to-metal construction, providing moisture resistance and long-term reliability in harsh environments including vacuum and high-humidity operational profiles.
