Product details
Overview
5962-8861007ZA from Integrated Device Technology (IDT) is a military-grade 2K × 16-bit dual-port static RAM with independent left/right asynchronous ports, 35ns maximum read cycle time, on-chip arbitration logic (MASTER mode), and 2V data retention for battery backup operation. It operates across –55°C to +125°C and is used in real-time avionics interprocessor communication systems requiring concurrent read/write access without external logic.
For engineers reviewing the 5962-8861007ZA datasheet, 5962-8861007ZA pinout, 5962-8861007ZA application, or 5962-8861007ZA equivalent, this page delivers verified military-spec timing parameters, BUSY arbitration behavior, 68-pin PGA package mapping, and MASTER/SLAVE expansion compatibility - critical for MIL-PRF-38535 QML-compliant system design and legacy defense electronics sustainment.
Technical Context
The 5962-8861007ZA implements fully asynchronous dual-port architecture with separate address, control, and I/O buses per port. Its on-chip arbitration logic resolves contention when both ports access the same memory location simultaneously, asserting open-drain BUSYL/BUSYR outputs to stall the lower-priority port.
As a MASTER device, it supports width expansion with IDT7143 SLAVE devices via BUSY signal routing; BUSY output on 5962-8861007ZA drives BUSY input on SLAVE parts, eliminating "Busy Lock-Out" in multi-chip 32-bit+ systems. It requires pull-up resistors on BUSY pins and dual VCC/GND connections for reliable operation.

|---|---|
| Memory Organization | 2K × 16-bit (32,768 bits), dual-port SRAM with independent left/right access paths |
| Access Time (tRC) | 35ns max - guarantees full-speed concurrent read/write in real-time embedded control loops |
| Operating Temperature | –55°C to +125°C - qualified per MIL-PRF-38535 QML Class V for flight-critical systems |

Pinout & Package
68-pin ceramic PGA (GU68 package), body size ≈1.18″ × 1.18″ × 0.16″, compliant with MIL-STD-883. Both VCC and GND pins are duplicated for noise immunity and current distribution in high-reliability systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| R/WLUB / R/WRUB | Upper Byte Read/Write Enable | Byte-level write control - allows selective 8-bit updates without disturbing adjacent byte |
| R/WLLB / R/WRLB | Lower Byte Read/Write Enable | Enables independent lower-byte writes; essential for mixed-data-size protocol handling |
| OEL / OER | Output Enable (Left/Right) | Tri-states I/O drivers independently - prevents bus contention in shared-memory topologies |
| BUSYL / BUSYR | Busy Flag (Open-Drain Output) | Signals port contention; requires external pull-up; used for hardware stall or interrupt generation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IDT7133SA35JGI | Commercial-grade, 35ns, 68-pin PLCC, 0°C to +70°C - lacks MIL-PRF-38535 qualification and 2V retention | Not suitable for flight hardware; usable only in ground-test or lab-bench prototypes | Select only for cost-sensitive non-mission-critical development where temperature range and radiation tolerance are irrelevant |
| CY7C133-35JC | Cypress 2K×16 dual-port, 35ns, 68-pin PGA - no built-in arbitration logic; requires external BUSY management | Increases PCB area and BOM count; adds timing uncertainty in contention resolution | Choose only if existing design uses Cypress ecosystem and can accommodate external arbitration logic |
Compared with IDT7133SA35JGI and CY7C133-35JC, the 5962-8861007ZA uniquely delivers MIL-qualified arbitration, 2V retention, and guaranteed –55°C to +125°C operation - making it irreplaceable in deployed avionics without redesigning the memory subsystem.

FAQ
What is the operating temperature range certified for the 5962-8861007ZA?
The 5962-8861007ZA is certified for operation from –55°C to +125°C per MIL-PRF-38535 QML Class V requirements. This range is validated through temperature cycling, burn-in, and parametric testing across the full military grade - not derived from commercial or industrial variants. The 5962-8861007ZA maintains all timing specifications (e.g., 35ns tRC) across this entire range.
Does the 5962-8861007ZA include on-chip arbitration logic, and how does it function?
Yes, the 5962-8861007ZA includes dedicated on-chip arbitration logic as a MASTER device. When both ports attempt access to the same memory location, it asserts BUSYL or BUSYR within ≤35ns (tBDD) to stall the lower-priority port. The 5962-8861007ZA's BUSY outputs are open-drain and require external pull-up resistors - a requirement explicitly documented in the functional description and pin diagrams.
Can the 5962-8861007ZA retain data at 2V, and what is the typical retention current?
Yes, the 5962-8861007ZA supports data retention at VCC = 2.0V minimum. Per Table 8, ICCDR is 100µA typical and 4000µA maximum under military temperature conditions (–55°C to +125°C). This 2V capability enables integration into battery-backed systems such as flight data recorders, where main power may fail but critical state must persist.
What package type is used for the 5962-8861007ZA, and are there any layout constraints?
The 5962-8861007ZA uses a 68-pin ceramic PGA (GU68) package. Layout constraints include mandatory connection of both VCC pins to the 5V supply and both GND pins to ground - failure to do so causes unreliable operation. The package body measures approximately 1.18″ × 1.18″ × 0.16″, and pin 1 orientation follows standard PGA marking conventions shown in Drawing 2746 drw 04.
How does the 5962-8861007ZA differ from the IDT7143 SLAVE device in a MASTER/SLAVE configuration?
The 5962-8861007ZA functions exclusively as the MASTER: its BUSY pins are open-drain outputs used to drive BUSY inputs on IDT7143 SLAVE devices. The 5962-8861007ZA contains arbitration logic; IDT7143 does not. In width-expansion systems, only the 5962-8861007ZA resolves contention - SLAVES rely entirely on its BUSY signal to inhibit writes, preventing "Busy Lock-Out" in multi-chip configurations.
