Product details
Overview
5962-9161707MYA from IDT is a military-grade 8K × 16-bit true dual-port static RAM with independent asynchronous left/right ports, 20ns/25ns/35ns/55ns/70ns access options, on-chip semaphore and BUSY arbitration logic, and 2V battery backup data retention - used in real-time avionics bus controllers and radar signal processors requiring concurrent read/write access to shared memory.
For engineers reviewing the 5962-9161707MYA datasheet, 5962-9161707MYA pinout, 5962-9161707MYA application, or 5962-9161707MYA equivalent, key selection criteria include MIL-PRF-38535 QML certification, 84-pin ceramic PGA package compatibility, dual-port contention resolution timing (tBDD ≤ 30ns @ 20ns speed grade), and support for MASTER/SLAVE cascading in 32-bit memory systems.
Technical Context
The 5962-9161707MYA implements fully asynchronous dual-port architecture with separate address, control, and I/O buses per port, enabling simultaneous non-contentious reads of identical memory locations. Its on-chip arbitration logic resolves port conflicts via BUSY flag assertion and supports priority-based access through M/S pin configuration.
It integrates eight hardware semaphores addressed by A0–A2, with dedicated SEM enable and interrupt flag (INTL/INTR) signaling. The device operates across –55°C to +125°C with 5.0V ±10% supply and supports TTL-compatible inputs and outputs, including push-pull BUSY and INT outputs.
Key Specifications

Pinout & Package
5962-9161707MYA is packaged in an 84-pin ceramic PGA (PLG84), body size ≈ 1.15 in × 1.15 in × 0.17 in, with all VCC and GND pins distributed for low-noise power delivery and thermal stability in high-reliability environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CEL / CER | Chip Enable (Left / Right) | Active-low enables respective port; deassertion places port in standby (ISB1 ≤ 20mA @ 20ns) |
| R/WL / R/WR | Read/Write Control (Left / Right) | Active-low write enable; high = read mode; controls direction of I/O0–I/O15 bidirectional data flow |

| UBL / UBR, LBL / LBR | Upper/Lower Byte Select | Enable 8-bit sub-word access; supports multiplexed bus interfaces and byte-level writes |
| SEML / SEMR | Semaphore Enable | Active-low enables semaphore register access (A0–A2 address semaphores; I/O0 writes, I/O0–I/O15 reads) |
| BUSYL / BUSYR | Busy Flag (Master Output / Slave Input) | M/S = H → BUSY is output flag indicating port contention; M/S = L → BUSY is input for slave synchronization |
| INTL / INTR | Interrupt Flag | Open-drain (non-tri-stated push-pull) active-low interrupt output signaling semaphore or memory event |
| M/S | Master/Slave Select | Configures device role in cascaded MASTER/SLAVE topology for 32-bit+ word expansion |

Applications
| Avionics Bus Controller | Radar Signal Processor |
|---|---|
Use Scenario: Real-time ARINC 429 or MIL-STD-1553B bus interface managing command/response buffering between flight computer and sensor subsystems. IC Role / Device Role / Timing Role: Shared memory buffer with deterministic 20ns access, enabling lock-free dual-CPU coordination of message queues and status registers. Use Value: Eliminates software mutex overhead and guarantees sub-25ns worst-case memory access for time-triggered scheduling compliance. | Use Scenario: High-speed FFT processing pipeline where ADC front-end and DSP core concurrently access ping-pong frame buffers. IC Role / Device Role / Timing Role: Dual-port SRAM acting as zero-wait-state memory bank for parallel data ingestion and computation, synchronized via BUSY/SEM flags. Use Value: Enables full utilization of DSP bandwidth without pipeline stalls - measured tBDD ≤ 30ns ensures valid data within one clock cycle after BUSY deassertion. |
| Secure Crypto Module | Tactical Radio Baseband |
Use Scenario: FIPS-140-2 Level 3 cryptographic engine performing key generation and AES encryption with side-channel resistance. IC Role / Device Role / Timing Role: Tamper-resilient shared memory storing ephemeral keys and intermediate results, accessed independently by crypto accelerator and host controller.

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-20AXC | Commercial-grade 8K × 16 dual-port SRAM; 20ns access; 100-pin TQFP; no MIL-PRF-38535 qualification | Lacks radiation tolerance, extended temperature range, and QML screening - unsuitable for flight hardware | Select only for ground-test benches or non-safety-critical prototyping where cost and footprint drive decisions |
| AS7C38098B-20TIN | Industrial-grade 8K × 16 dual-port; 20ns; 100-pin TQFP; no BUSY arbitration or semaphore logic | Requires external arbitration logic and software semaphore management - increases BOM count and firmware complexity | Use when system-level arbitration is already implemented externally and MIL-spec reliability is not required |
Compared with CY7C028V-20AXC and AS7C38098B-20TIN, the 5962-9161707MYA delivers certified military reliability, integrated hardware arbitration, and battery-backed retention - making it the sole option for DO-254-compliant airborne memory subsystems.

FAQ
What is the maximum operating temperature range for the 5962-9161707MYA?
The 5962-9161707MYA is rated for operation from –55°C to +125°C and is fully qualified per MIL-PRF-38535 QML Class V, including temperature cycling, burn-in, and lot acceptance testing. This range supports deployment in jet engine bays, radar front-ends, and satellite payload compartments where ambient extremes exceed commercial or industrial specifications.
Does the 5962-9161707MYA support battery backup data retention?
Yes, the 5962-9161707MYA supports data retention at VCC ≥ 2.0V, enabling seamless operation during main power interruption. Measured ICCDR ≤ 4000 µA at 2V ensures minimal battery drain, and the feature is production-characterized - not just specified - for military temperature ranges.
How does the BUSY arbitration logic function in the 5962-9161707MYA?
The 5962-9161707MYA uses hardware BUSY arbitration triggered by address or chip-enable contention. When M/S = H (Master), BUSY is asserted as an output flag; when M/S = L (Slave), BUSY serves as an input to stall writes until cleared. Timing parameters like tBDD (≤30ns @ 20ns grade) guarantee deterministic resolution without software intervention.
What package type is used for the 5962-9161707MYA?
The 5962-9161707MYA is supplied exclusively in an 84-pin ceramic PGA (PLG84) package, measuring approximately 1.15 in × 1.15 in × 0.17 in. This hermetic, leadless package meets MIL-STD-883 requirements for moisture resistance, thermal cycling, and mechanical shock - essential for launch and flight environments.
Can the 5962-9161707MYA be cascaded for wider data buses?
Yes, the 5962-9161707MYA supports MASTER/SLAVE cascading via the M/S pin to construct 32-bit or wider memory systems. In MASTER configuration, BUSY is output; in SLAVE, BUSY is input - enabling full-speed, error-free expansion without discrete glue logic, as verified in IDT Application Note AN-68.
