Product details
Overview
5962-8861011UA from Integrated Device Technology (IDT) is a military-grade 2K × 16-bit dual-port static RAM with independent left/right asynchronous ports, 35ns max read cycle time, on-chip port arbitration logic (MASTER mode), and BUSY flag signaling for contention resolution - used in real-time avionics data buffers and radar signal processing subsystems requiring deterministic dual-access memory.
For engineers reviewing the 5962-8861011UA datasheet, 5962-8861011UA pinout, 5962-8861011UA application, or 5962-8861011UA equivalent, this page delivers verified military-spec timing parameters, validated 68-pin PGA package mapping, confirmed MASTER arbitration behavior, and precise BUSY input/output role differentiation between IDT7133 and IDT7143 variants.
Technical Context
The 5962-8861011UA implements fully asynchronous dual-port operation with separate address, control, and I/O buses per port - enabling concurrent read/write access to any memory location without internal synchronization overhead. It features dedicated upper/lower byte write enables (R/WLUB/R/WLLB and R/WRUB/R/WRLB) and TTL-compatible 5V ±10% single-supply operation.
As a MIL-PRF-38535 QML-qualified IDT7133 variant, it integrates on-chip arbitration logic and an open-drain BUSYL/BUSYR output (requiring external pull-up) to resolve simultaneous accesses to identical addresses - unlike the IDT7143 SLAVE which accepts BUSY as an input-only write-inhibit signal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 2,048 × 16 bits (32 KB total); supports independent 16-bit word access per port |
| Access Time | 35 ns (max) at -55°C to +125°C; guarantees deterministic latency for hard real-time systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8861012UA | IDT7143 SLAVE variant; BUSY pin is input-only; no on-chip arbitration logic | Used only in MASTER/SLAVE width-expansion configurations; cannot operate standalone as arbitration node | Select when expanding to 32+ bit bus width with 5962-8861011UA as MASTER; requires BUSY routing from MASTER |
| 5962-9315901Q2A | Cypress CY7C028V (2K × 16); 25ns commercial speed grade; non-military screening | Lacks MIL-PRF-38535 qualification; rated only for -40°C to +85°C industrial temp range | Acceptable for ground-based test equipment where radiation tolerance and extended temperature are not required |
Compared with 5962-8861011UA, the 5962-8861012UA serves exclusively as a SLAVE in width-expanded systems and lacks arbitration capability, while the 5962-9315901Q2A omits military qualification and offers faster speed only in commercial conditions - making 5962-8861011UA irreplaceable for flight-critical arbitration and environmental robustness.

FAQ
What is the operating temperature range for the 5962-8861011UA?
The 5962-8861011UA is qualified for operation across -55°C to +125°C ambient temperature per MIL-PRF-38535 Class B requirements. This full military temperature range is guaranteed for all electrical specifications including 35ns access time, standby current, and arbitration timing - no derating is required at temperature extremes.
Does the 5962-8861011UA support battery backup data retention?
No, the 5962-8861011UA is an SA (Standard Active) variant and does not support battery backup data retention. Data retention capability (down to 2V) is exclusive to LA (Low Active) versions such as 5962-8861011LA. The 5962-8861011UA requires continuous 5V ±10% supply for volatile operation.
How is BUSY functionality implemented on the 5962-8861011UA?
As an IDT7133 MASTER device, the 5962-8861011UA provides BUSYL and BUSYR as open-drain outputs that require external pull-up resistors. These signals assert when both ports attempt simultaneous access to the same memory address - enabling hardware stall of the contending port without software intervention.
Can the 5962-8861011UA be used without external arbitration logic?
Yes - the 5962-8861011UA contains fully integrated on-chip arbitration logic (tAPS = 5 ns setup). It resolves port contention autonomously and outputs BUSY status, eliminating the need for external priority encoders, CPLDs, or arbitration firmware - a key requirement for DO-254 Level A certified systems.
What package type is used for the 5962-8861011UA?
The 5962-8861011UA uses a 68-pin ceramic PGA (GU68) package per MIL-PRF-38535 QML requirements. Its hermetically sealed ceramic construction provides superior moisture resistance, thermal stability, and mechanical robustness compared to plastic or flatpack alternatives - essential for aerospace deployment.
