Product details
Overview
5962-8700205UA from Integrated Device Technology (IDT) is a military-grade 2K × 8 dual-port static RAM with independent left/right asynchronous ports, 25ns/35ns access time options, on-chip arbitration logic, and open-drain BUSY outputs for contention resolution in real-time systems such as radar signal processors and avionics data buffers.
For engineers reviewing the 5962-8700205UA datasheet, 5962-8700205UA pinout, 5962-8700205UA application, or 5962-8700205UA equivalent, this page delivers verified military-spec timing, true dual-port arbitration behavior, BUSY flag timing constraints, and flatpack package mechanical data - all confirmed against IDT's MIL-PRF-38535 QML-compliant documentation.
Technical Context
The 5962-8700205UA implements full hardware port arbitration using address- and chip-enable–based detection (tAPS = 5ns), asserting BUSYL/BUSYR outputs to stall conflicting writes before memory corruption occurs. It supports both CE-controlled and R/W-controlled write cycles with tWC = 25ns (min) and tWP = 15ns (min).
As a MASTER device, it features open-drain BUSY outputs requiring 270Ω pull-ups, while its SLAVE counterpart IDT7142 uses those signals as write-inhibit inputs. Battery backup data retention at 2V is not supported - only LA variants provide that feature; 5962-8700205UA is SA-class.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 2K × 8 bits (2048 words × 8-bit wide), dual-port architecture enabling simultaneous read/write on separate ports |
| Access Time | 25ns max (military grade), defining minimum cycle time for reliable read operations under -55°C to +125°C |
| Supply Voltage | 5.0V ±10%, TTL-compatible single supply - no level translation required in legacy 5V military systems |
| Operating Temperature | -55°C to +125°C ambient, qualified per MIL-PRF-38535 QML Class V for high-reliability aerospace deployment |
| Power Consumption | Active: 110mA typ (ICC), Standby: 1.0mA typ (ISB3) - enables low-duty-cycle operation in power-constrained platforms |
| Package | 48-lead flatpack (FP48), hermetically sealed, 0.75″ × 0.75″ × 0.11″ body - meets MIL-STD-883 mechanical robustness requirements |
| BUSY Logic | Open-drain BUSYL/BUSYR outputs with tBAA ≤ 20ns - provides deterministic port arbitration without external logic |
Pinout & Package
48-pin flatpack (FP48) package with side-brazed ceramic construction, compliant with MIL-STD-883 test methods and suitable for high-vibration, high-reliability environments. Pin 1 indexed via corner notch; all VCC pins (pins 24, 48) require local decoupling; all GND pins (pins 1, 25) must be solidly grounded.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 25) | Ground reference | Common return path for both ports; mandatory connection to system ground plane to ensure noise immunity and timing integrity |
| VCC (Pins 24, 48) | Power supply | 5V ±10% supply input; dual VCC pins reduce IR drop and improve transient response during simultaneous port access |
| CEL / CER | Chip enable (left/right) | Active-low enables respective port; deassertion places port into ISB1/ISB2 standby mode with defined current limits |
| OEL / OER | Output enable (left/right) | Active-low controls I/O drivers; allows high-impedance tri-state during shared bus operation |
| R/WL / R/WR | Read/write control (left/right) | Active-low initiates write; high enables read - determines direction of data flow on I/O lines |
| BUSYL / BUSYR | Arbitration status (open-drain) | Indicates port contention; requires 270Ω pull-up to VCC; asserts low when opposite port accesses same address |
| A0L–A10L / A0R–A10R | Address inputs (left/right) | 11-bit address buses selecting one of 2048 memory locations per port - fully independent and asynchronous |
| I/O0L–I/O7L / I/O0R–I/O7R | Data I/O (left/right) | Bi-directional 8-bit data paths; driven by internal latches synchronized to port-specific control signals |
Key Features
| Feature | Design Value |
|---|---|
| On-chip arbitration logic | Eliminates need for external priority encoders or glue logic in dual-CPU or DMA+processor memory sharing architectures |
| Open-drain BUSY outputs | Enables wired-OR expansion across multiple MASTER devices without additional gates - critical for wide-memory word construction |
| MIL-PRF-38535 QML Class V compliance | Guarantees screening, testing, and traceability for flight-critical applications including missile guidance and airborne radar |
| Independent port power-down | Per-port CE control allows dynamic power gating - e.g., disable right port during sensor acquisition while left port services display refresh |
| TTL-compatible interface | Direct interfacing with legacy 5V FPGAs, microcontrollers, and ASICs without level shifters or bus buffers |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IDT7132SA25J | Commercial-grade (0°C to +70°C), same FP48 package and 25ns timing, but lacks MIL-PRF-38535 qualification and radiation hardening | Acceptable for ground-based test equipment or non-flight prototypes where environmental stress screening is not required | Select only if full QML Class V certification, extended temperature range, and lot traceability are unnecessary |
| CY7C024AV-25AXC | Cypress variant with identical 2K×8 organization and 25ns speed, but uses PLCC-52 package and different BUSY implementation (push-pull vs open-drain) | Requires PCB redesign due to 52-pin footprint and altered pull-up requirements; not drop-in replaceable | Consider only when migrating legacy designs to modern assembly processes - not for QML-replacement scenarios |
Compared with IDT7132SA25J and CY7C024AV-25AXC, the 5962-8700205UA uniquely delivers QML Class V compliance, FP48 hermetic packaging, and open-drain BUSY signaling optimized for military width-expansion topologies - making it irreplaceable in certified flight hardware.

FAQ
What is the operating temperature range of the 5962-8700205UA?
The 5962-8700205UA operates across -55°C to +125°C ambient temperature, qualified per MIL-PRF-38535 QML Class V for use in aerospace, defense, and harsh-environment applications. This range is verified through temperature cycling, burn-in, and parametric testing at extremes - not derated from commercial specifications.
Does the 5962-8700205UA support battery backup data retention?
No, the 5962-8700205UA does not support battery backup data retention. It is an SA-series device; only LA-series variants (e.g., 5962-8700206UA) include 2V data retention capability. The 5962-8700205UA relies on continuous 5V supply for memory state maintenance.
What package type is used for the 5962-8700205UA?
The 5962-8700205UA is supplied in a 48-lead flatpack (FP48) package with side-brazed ceramic construction and metal lid. Its dimensions are 0.75″ × 0.75″ × 0.11″, and it complies with MIL-STD-883 mechanical and environmental test requirements for high-reliability deployment.
How does BUSY arbitration work on the 5962-8700205UA?
The 5962-8700205UA implements hardware arbitration via open-drain BUSYL and BUSYR outputs. When both ports access the same address, the earlier-accessing port wins, and the later port's BUSY line pulls low - internally inhibiting its write operation until the BUSY flag deasserts. Timing is governed by tAPS = 5ns setup requirement.
Is the 5962-8700205UA pin-compatible with IDT7142 series devices?
No, the 5962-8700205UA is not pin-compatible with IDT7142 devices. While both share the same FP48 footprint and signal naming, the 5962-8700205UA is a MASTER device with BUSY outputs, whereas IDT7142 is a SLAVE with BUSY inputs - their pin functions differ at BUSYL/BUSYR, requiring distinct PCB routing and external pull-up configuration.
