Product details
Overview
5962-9161701MXA 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 times (military grade), on-chip semaphore logic, and full hardware arbitration - deployed in real-time avionics data buffers and radar signal processing memory subsystems.
For engineers reviewing the 5962-9161701MXA datasheet, 5962-9161701MXA pinout, 5962-9161701MXA application, or 5962-9161701MXA 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 system integration.
Technical Context
The 5962-9161701MXA implements fully asynchronous dual-port operation with separate address, control, and I/O buses per port, enabling simultaneous read/write to the same location only when BUSY arbitration prevents contention. Its on-chip port arbitration logic enforces deterministic priority via M/S pin configuration (Master outputs BUSY; Slave inputs BUSY).
It supports semaphore flag management across eight dedicated flags addressed by A0–A2, with tSWRD = 5ns SEM write-to-read latency and tSPS = 5ns contention window - critical for lock-free inter-processor communication in flight control computers. Battery backup retention at 2V is specified only for L-version variants.
Key Specifications

| Memory Organization | 8K × 16-bit (128 Kbit), two independent addressable ports |
| Access Time (tAA) | 20ns / 25ns / 35ns / 55ns / 70ns max - defines minimum cycle time for reliable read setup in MIL-STD-883 Class B testing |
| Operating Voltage | 5.0 V ±10% - TTL-compatible single supply; no level-shifting required in legacy 5V military systems |
| Temperature Range | −55°C to +125°C - qualified per MIL-PRF-38535 QML Class V for high-reliability aerospace deployment |
| Power Consumption | Active: 160–370 mA typ. (depends on speed grade); Full standby: ≤1.0 mA (S) / ≤0.2 mA (L) - enables low-quiescent subsystem power budgeting |

Pinout & Package
5962-9161701MXA is supplied in an 84-pin ceramic PGA (GU84 package), with VCC and GND distributed across multiple pins for low-impedance power delivery and noise immunity in high-speed military environments.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| CEL / CER | Chip Enable (Left / Right) | Asynchronous enable per port; deassertion places respective port in high-Z / standby mode |
| R/WL / R/WR | Read/Write Control (Left / Right) | Active-low; controls direction of data flow on associated I/O bus during enabled cycles |
| OEL / OER | Output Enable (Left / Right) | Independent output gating - allows partial bus driving without disabling chip enable |
| UBL / UBR, LBL / LBR | Upper/Lower Byte Select | Enables byte-level granularity for 16-bit bus multiplexing and 32-bit expansion via cascaded MASTER/SLAVE |
| SEML / SEMR | Semaphore Enable | Activates semaphore register access (A0–A2 addressed); disables RAM array access when asserted |
| BUSYL / BUSYR | Busy Flag (Master Output / Slave Input) | M/S = H: BUSY is driven output indicating port contention; M/S = L: BUSY is sampled input for arbitration coordination |
| INTL / INTR | Interrupt Flag | Open-drain push-pull output signals semaphore or error event; requires external pull-up |
| A0L–A12L / A0R–A12R | Address Inputs | 13-bit addressing per port → 8K locations; non-multiplexed, fully parallel |
| I/O0L–I/O15L / I/O0R–I/O15R | Data I/O Bus | Bi-directional 16-bit data path per port; electrically isolated between ports |
| M/S | Master/Slave Select | Configures device role in cascaded 32-bit+ systems; determines BUSY pin function (input vs. output) |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Avionics Data Buffering | Radar Signal Processing Memory |
|---|---|
|
Use Scenario: Real-time buffering of ADC samples between sensor front-end and DSP engine in airborne radar transceivers. IC Role / Device Role / Timing Role: Dual-port RAM acts as ping-pong buffer - one port accepts streaming digitized RF data while the other feeds processed results to display subsystem. Use Value: 20ns access time enables sustained 50 MHz sampling throughput; hardware arbitration prevents FIFO overflow during burst-mode acquisition. |
Use Scenario: Shared memory between tracker CPU and beamformer FPGA in phased-array radar systems. IC Role / Device Role / Timing Role: Acts as coherently accessed scratchpad with semaphore-controlled ownership transfer for target list updates. Use Value: On-chip semaphores eliminate polling delays; tSPS = 5ns ensures sub-cycle lock acquisition for deterministic latency-critical tracking loops. |
| Flight Control Computer Inter-Processor Link | Mission Computer I/O Expansion Interface |
|
Use Scenario: Communication channel between primary and backup flight control processors executing dissimilar redundancy algorithms. IC Role / Device Role / Timing Role: Provides fault-isolated shared memory with BUSY-driven arbitration to prevent conflicting writes during failover transitions. Use Value: M/S-configurable master/slave roles allow dynamic reassignment; −55°C to +125°C operation sustains functionality across extreme aircraft envelope conditions. |
Use Scenario: Memory-mapped interface between mission computer CPU and modular I/O backplane controllers in tactical vehicles. IC Role / Device Role / Timing Role: Serves as configurable 16-bit peripheral register bank with byte-select capability for mixed-width legacy peripherals. Use Value: UBL/LBL enables selective access to upper/lower bytes - reduces bus transaction count for 8-bit sensor registers without software masking. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C133-25JVXI | Commercial-grade 8K×16, 25ns access, 100-pin TQFP, no MIL-PRF-38535 qualification | Lacks radiation tolerance, extended temperature screening, and BUSY arbitration timing guarantees | Acceptable for ground-test benches or non-flight prototypes where cost and footprint drive selection |
| AS7C38098B-20JIN | Industrial-grade 8K×16, 20ns access, 84-pin PLCC, no on-chip semaphore or BUSY logic | Requires external arbitration logic and interrupt controller; no native semaphore register set | Suitable for cost-sensitive embedded systems where software-managed locking suffices and MIL-spec is not mandated |
Compared with CY7C133-25JVXI and AS7C38098B-20JIN, the 5962-9161701MXA uniquely delivers QML Class V screening, deterministic hardware arbitration with sub-20ns BUSY response, and integrated semaphore registers - eliminating external logic and ensuring compliance in certified flight hardware.

FAQ
What is the operating temperature range for the 5962-9161701MXA?
The 5962-9161701MXA is rated for −55°C to +125°C ambient operation and qualified per MIL-PRF-38535 QML Class V. This range is validated through thermal cycling, burn-in, and parametric testing across the full span - essential for deployment in jet engine bays and satellite payload compartments where thermal extremes occur.
Does the 5962-9161701MXA support battery backup data retention?
The 5962-9161701MXA does not specify battery backup retention in its military-grade documentation. While the commercial L-version (e.g., IDT7025L) supports 2V data retention, the 5962-9161701MXA - as a QML Class V derivative - omits this feature in favor of enhanced radiation tolerance and extended temperature performance. Retention is not guaranteed below 4.5V.
How does the BUSY arbitration work on the 5962-9161701MXA?
When configured as Master (M/S = H), the 5962-9161701MXA asserts BUSY on the opposing port if both ports attempt simultaneous access to the same address. As Slave (M/S = L), it samples BUSY to delay its own write until the Master releases contention. Timing parameters tBAA, tBDA, and tBDD are guaranteed per speed grade - e.g., ≤20ns for the 20ns variant - ensuring deterministic resolution.
Can the 5962-9161701MXA be used in a 32-bit memory system?
Yes - the 5962-9161701MXA supports 32-bit expansion via MASTER/SLAVE cascading. One device operates as Master (M/S = H) driving BUSY; the second as Slave (M/S = L) responding to BUSY. Combined with UBL/LBL and CE control, this enables full-word access without external logic - a key design advantage over discrete SRAM + PAL solutions.
What package type is used for the 5962-9161701MXA?
The 5962-9161701MXA uses an 84-pin ceramic Pin Grid Array (GU84), measuring 1.15″ × 1.15″ × 0.17″. This hermetic PGA package meets MIL-STD-883 requirements for moisture resistance, thermal stability, and mechanical robustness - standard for high-reliability military and space applications.
