Product details
Overview
5962-8866515UA from Integrated Device Technology (IDT) is a military-grade 2K × 16 dual-port static RAM with independent left/right asynchronous ports, 35ns max read cycle time, on-chip arbitration logic (MASTER mode), and BUSY flag signaling - used in real-time avionics data buffering where concurrent CPU and DSP access to shared memory must avoid contention.
For engineers reviewing the 5962-8866515UA datasheet, 5962-8866515UA pinout, 5962-8866515UA application, or 5962-8866515UA equivalent, this page delivers verified military-spec timing, MASTER/SLAVE expansion capability, 68-pin PGA package mapping, battery backup support (2V retention), and direct substitution guidance for QML-38535-compliant systems.
Technical Context
The 5962-8866515UA implements fully asynchronous dual-port operation with separate address, control, and I/O buses per port - enabling simultaneous read/write to distinct memory locations without arbitration overhead. Its on-chip arbitration logic resolves port-to-port contention at the same address by asserting BUSY to the later-arriving port.
As a MASTER device, it features open-drain BUSY output requiring external pull-up, while supporting width expansion via SLAVE IDT7143 devices. It operates across –55°C to +125°C with single 5V ±10% supply and meets MIL-PRF-38535 QML Class V requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 2K × 16 (32,768 bits), dual-port SRAM with independent left/right access paths |
| Access Time (tRC) | 35ns maximum - guarantees deterministic latency for hard real-time interrupt servicing |
| Operating Temperature | –55°C to +125°C - qualified per MIL-PRF-38535 QML Class V for flight-critical systems |
| Power Supply | 5.0V ±10% - compatible with legacy military power rails; no auxiliary voltage required |
| Standby Current (ISB1) | 25mA max (both ports TTL-level standby) - enables low-power sleep modes in mission-critical hold states |
| Data Retention | 2V minimum VCC - supports battery-backed operation during main power loss without data corruption |
| Package | 68-pin ceramic PGA (PLG68) - hermetically sealed, leadless, high-reliability mechanical interface |
Pinout & Package
68-pin ceramic PGA (PLG68) package: 0.95″ × 0.95″ × 0.17″ body, hermetic ceramic construction, gold-plated leads, compliant with MIL-STD-883 test methods.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A10L | Left Port Address Inputs | 11-bit address bus for left-side memory access (2K = 211) |
| A0R–A10R | Right Port Address Inputs | Independent 11-bit address bus for right-side access - enables true parallel addressing |
| I/O0L–I/O15L | Left Port Data I/O | 16-bit bidirectional data path; high-impedance when OEL or CEL inactive |
| I/O0R–I/O15R | Right Port Data I/O | Independent 16-bit data path - no shared bus contention between ports |
| CEL / CER | Chip Enable (Left/Right) | Active-low enables respective port; controls power-down state and arbitration activation |
| R/WLUB / R/WRUB | Upper Byte Read/Write Enable | Byte-selective write control - allows partial-word updates without read-modify-write |
| R/WLLB / R/WRLB | Lower Byte Read/Write Enable | Enables independent 8-bit writes to lower byte - critical for protocol-aligned data packing |
| OEL / OER | Output Enable (Left/Right) | Controls tri-state of I/O drivers; decoupled from CE for flexible bus management |
| BUSYL / BUSYR | Busy Flag (Left/Right) | BUSYL is open-drain output (MASTER); BUSYR is input (SLAVE-compatible) - enables hardware stall signaling |
| VCC (pins 17, 51) | Power Supply | Both pins must be connected to 5V ±10%; failure causes functional instability per datasheet note |
| GND (pins 35, 68) | Ground Reference | Both pins must be connected to system ground; ensures signal integrity and thermal stability |
Key Features
| Feature | Design Value |
|---|---|
| On-chip port arbitration logic | Resolves same-address contention without external logic - eliminates race conditions in dual-CPU systems |
| Separate upper/lower byte write enables | Enables atomic 8-bit writes to either half of 16-bit word - essential for register-mapped peripheral interfacing |
| Open-drain BUSY output with priority resolution | Allows wired-OR of multiple BUSY signals for system-level interrupt generation on contention events |
| 2V data retention mode | Maintains full memory contents during brown-out or battery-backup operation - validated per MIL-STD-883 method 1017 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8959901XA | Same 2K×16 organization, 55ns access, QML-38535 Class V, but IDT7143 SLAVE variant - lacks on-chip arbitration logic and BUSY output | Requires external arbitration or MASTER coordination; suitable only as width-expansion slave, not standalone replacement | Select only when expanding 32-bit+ systems with a dedicated MASTER; cannot replace 5962-8866515UA in standalone MASTER role |
| 5962-9214001MXA | Cypress CY7C028V - 2K×16, 25ns, QML-38535 Class V, integrated BUSY arbitration, but uses 100-pin TQFP (PNG100) instead of 68-pin PGA | Requires PCB redesign due to different footprint, pinout, and power sequencing; higher speed but incompatible mechanical interface | Choose only if board revision allows 100-pin TQFP layout change and faster timing is required; not drop-in |
Compared with 5962-8866515UA, 5962-8959901XA omits MASTER arbitration and requires external BUSY coordination, while 5962-9214001MXA offers faster access but mandates mechanical redesign - making 5962-8866515UA uniquely suited for legacy 68-pin PGA-based QML systems needing self-contained arbitration.

FAQ
What is the maximum operating temperature range certified for the 5962-8866515UA?
The 5962-8866515UA is certified for operation from –55°C to +125°C per MIL-PRF-38535 QML Class V requirements. This rating is verified through temperature cycling, burn-in, and parametric testing across the full range - ensuring reliability in jet engine bays, missile canisters, and space-qualified payloads where thermal extremes are routine. The 5962-8866515UA maintains full functionality and timing compliance throughout this range.
Does the 5962-8866515UA support battery backup operation, and what is the minimum retention voltage?
Yes, the 5962-8866515UA supports battery backup operation with guaranteed data retention down to 2.0V (VDR = 2.0V min). At this voltage, typical retention current is 100µA, and the device holds all 32,768 bits intact without refresh - validated per MIL-STD-883 method 1017. This capability is intrinsic to the LA variant design and applies directly to the 5962-8866515UA, enabling safe operation during main power failure in mission-critical systems.
Is the 5962-8866515UA pin-compatible with commercial-grade IDT7133SA/LA devices?
No - the 5962-8866515UA uses the same 68-pin PGA (PLG68) footprint and identical pinout as commercial IDT7133 devices, but incorporates enhanced screening, lot traceability, and extended temperature testing per MIL-PRF-38535. While electrically and mechanically compatible at the board level, it is not a drop-in replacement without requalification due to differences in radiation hardness, burn-in protocols, and conformance documentation required for military deployment.
How does the BUSY arbitration logic function in the 5962-8866515UA during simultaneous same-address access?
When both ports attempt access to the same memory location, the 5962-8866515UA's on-chip arbitration asserts BUSYL or BUSYR (whichever port arrives second) within 30ns (tBAA max). The asserted BUSY signal gates the write enable path, preventing data corruption. The winning port proceeds unimpeded; the stalled port must wait until BUSY deasserts - a hardware-enforced, zero-software-overhead resolution mechanism unique to the MASTER 5962-8866515UA.
What package type and mounting configuration is used for the 5962-8866515UA?
The 5962-8866515UA is supplied in a 68-pin ceramic PGA (PLG68) package: 0.95″ × 0.95″ × 0.17″ hermetically sealed body with gold-plated, solderable pins. It is designed for through-hole mounting with standard PGA sockets or direct soldering using MIL-STD-2000-compliant reflow profiles. Pin 1 is marked with a dot; orientation follows JEDEC MO-058 standards, and both VCC (pins 17, 51) and GND (pins 35, 68) require mandatory connection per datasheet note.
