Product details
Overview
5962-9161708MXA from IDT is a military-grade 8K × 16-bit (128 Kbit) true dual-port static RAM with independent asynchronous left/right ports, 20 ns max access time, TTL-compatible 5V ±10% supply, and on-chip semaphore arbitration-designed for real-time avionics data buffering and radar signal processing systems requiring concurrent read/write access to shared memory.
For engineers reviewing the 5962-9161708MXA datasheet, 5962-9161708MXA pinout, 5962-9161708MXA application, or 5962-9161708MXA equivalent, this page delivers verified military-spec timing, BUSY/INT/SEM signaling behavior, 84-pin PGA package mapping, and direct alternatives for MIL-PRF-38535 QML-compliant embedded memory upgrades.
Technical Context
The 5962-9161708MXA implements fully asynchronous dual-port architecture with separate address, control, and I/O buses per port, enabling simultaneous non-contentious reads from identical memory locations. Its on-chip arbitration logic resolves port contention via hardware BUSY flag assertion and supports master/slave cascading for 32-bit+ word expansion.
It integrates full semaphore signaling (8 flags, addressed by A0–A2), interrupt flag generation, and battery backup data retention down to 2V. The device operates across –55°C to +125°C and meets MIL-PRF-38535 Class V requirements for high-reliability defense electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 8K × 16-bit (128 Kbit), true dual-port SRAM with independent left/right access paths |
| Access Time (max) | 20 ns - guarantees deterministic latency for real-time radar frame buffering and flight control data exchange |
| Operating Temperature | –55°C to +125°C - qualified per MIL-PRF-38535 Class V for airborne and spaceborne platforms |
| Supply Voltage | 5.0 V ±10% - TTL-compatible single-supply operation; no level-shifting required in legacy avionics designs |

Pinout & Package
5962-9161708MXA is housed in an 84-pin ceramic pin-grid array (PLG84) package measuring approximately 1.15 in × 1.15 in × 0.17 in, with all VCC and GND pins distributed for low-noise power delivery and EMI resilience in high-density military PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CEL / CER | Chip Enable (Left / Right) | Independent port activation; deassertion places respective port in standby (ISB1–ISB4 modes) |
| R/WL / R/WR | Read/Write Control (Left / Right) | Active-low write enable; determines direction of data flow per port during active CE cycle |

| SEML / SEMR | Semaphore Enable | Activates 8-flag semaphore register accessed via A0–A2; critical for inter-processor synchronization |
| BUSYL / BUSYR | Busy Flag (Master Output / Slave Input) | M/S = H → BUSY output asserts during port contention; M/S = L → BUSY input gates write operations |
| INTL / INTR | Interrupt Flag | Open-collector push-pull output signals semaphore or memory event completion to host processor |
| A0L–A12L / A0R–A12R | Address Inputs | 13-bit addressing per port (8K = 2¹³); supports independent address spaces or mirrored access |
| I/O0L–I/O15L / I/O0R–I/O15R | Data I/O Bus | 16-bit bidirectional data path per port; electrically isolated to prevent cross-port coupling |
| M/S | Master/Slave Select | Configures device role in cascaded systems: Master asserts BUSY, Slave monitors BUSY to defer writes |
Key Features
| Feature | Design Value |
|---|---|
| True Dual-Port Architecture | Enables simultaneous read/write from same location-eliminates software polling or lock-step coordination in DSP co-processing |
| On-Chip Semaphore Logic | Eight hardware semaphores (A0–A2 addressable) provide atomic resource locking between processors without firmware overhead |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C028V-20AC | Commercial-grade 8K × 16, 20 ns, 100-pin TQFP; lacks MIL-PRF-38535 qualification and 2V retention | Not suitable for deployed military platforms; limited to ground-test or lab-based EW development systems | Select only for cost-sensitive prototyping where environmental ruggedness is not required. |
| AS7C38099B-20TC | Industrial-temp 8K × 16, 20 ns, 84-pin PLCC; no BUSY arbitration, no semaphore logic, no M/S cascade support | Requires external arbitration logic and interrupt handling-increases BOM count and layout complexity | Use only when legacy PLCC footprint compatibility is mandatory and hardware arbitration is implemented externally. |
Compared with CY7C028V-20AC and AS7C38099B-20TC, the 5962-9161708MXA uniquely delivers MIL-qualified reliability, integrated BUSY/SEM/INT signaling, and true contention-free dual-port operation-enabling single-chip memory subsystems in safety-critical flight systems without external glue logic.

FAQ
What is the maximum operating temperature range for the 5962-9161708MXA?
The 5962-9161708MXA is rated for operation from –55°C to +125°C and is qualified per MIL-PRF-38535 Class V. This full military temperature range ensures reliable performance in jet engine bays, missile canisters, and satellite payload compartments where thermal extremes are routine. The 5962-9161708MXA maintains specified timing and data integrity across this entire span without derating.
Does the 5962-9161708MXA support battery backup operation?
Yes, the 5962-9161708MXA supports data retention at VCC = 2.0 V minimum, enabling seamless battery backup during main power loss. This feature is intrinsic to the L-version silicon and requires no external circuitry-critical for maintaining flight-critical state data in avionics black boxes and inertial navigation systems. The 5962-9161708MXA retains valid data indefinitely at 2V within its qualified temperature range.
How does the BUSY arbitration work on the 5962-9161708MXA?
The 5962-9161708MXA uses hardware-driven BUSY arbitration: when M/S = H (Master), BUSY is an output that asserts during port contention to block the opposing port's write; when M/S = L (Slave), BUSY is an input that gates local write cycles. Timing parameters tBAA, tBDA, and tBDD are guaranteed at 20 ns max, ensuring deterministic resolution without software intervention. This behavior is validated in the 5962-9161708MXA datasheet Figure 13 and Table 14a.
Can the 5962-9161708MXA be used in a 32-bit data path configuration?
Yes, the 5962-9161708MXA supports 32-bit expansion via Master/Slave cascading using the M/S pin. Two devices can be configured-one as Master (M/S = H), one as Slave (M/S = L)-to form a synchronized 8K × 32-bit memory without external logic. The 5962-9161708MXA's dedicated BUSY handshake and identical timing ensure full-speed, error-free operation, as confirmed in the functional description on page 2 of the datasheet.
What package type is used for the 5962-9161708MXA?
The 5962-9161708MXA is packaged in an 84-pin ceramic pin-grid array (PLG84), with dimensions approximately 1.15 in × 1.15 in × 0.17 in. This hermetic, leadless PGA package meets MIL-STD-883 requirements for moisture resistance, thermal cycling, and mechanical robustness-essential for long-term deployment in harsh military environments. Pinout diagrams for PLG84 are provided in Figure 3 of the 5962-9161708MXA datasheet.
