Product details
Overview
5962-9150801MXA from IDT is a military-grade 16K × 8 (128 Kbit) true dual-port static RAM with independent left/right ports, 20 ns max access time, on-chip arbitration logic, and full semaphore support. It operates at 5.0 V ±10%, supports battery backup down to 2 V for data retention, and is qualified per MIL-PRF-38535 Class B for –55°C to +125°C operation.
For engineers reviewing the 5962-9150801MXA datasheet, 5962-9150801MXA pinout, 5962-9150801MXA application, or 5962-9150801MXA equivalent, this device is selected for high-reliability embedded systems requiring simultaneous asynchronous read/write access, hardware-managed port contention resolution, and deterministic interrupt/semaphore signaling in avionics, radar, and real-time control subsystems.
Technical Context
The 5962-9150801MXA implements fully asynchronous dual-port architecture with separate address, data, and control buses per port. Its on-chip arbitration logic resolves contention via BUSY flag assertion (output when M/S = H, input when M/S = L) and supports master/slave cascading for 16-bit+ word expansion.
It integrates dedicated semaphore registers (8 flags, addressed by A0–A2), interrupt generation (INTL/INTR), and power management: CE-controlled active/standby modes yield 750 mW typical active power and 5 mW standby (S version) or 1 mW standby (L version). Data retention at 2 V is guaranteed across military temperature range.

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 16K × 16 dual-port SRAM; 20 ns access, 3.3 V supply, TQFP-100 package | Lacks MIL qualification, no battery backup, wider data bus but incompatible voltage and pinout | Select only for non-military cost-sensitive designs where 3.3 V infrastructure exists and extended temperature is not required. |
| IS61LV25616AL-10TLI | Low-voltage 256K × 16 async SRAM; 10 ns access, 3.3 V, 100-pin TQFP; single-port only | No dual-port capability, no BUSY/semaphore logic, no MIL spec, no 2 V retention | Use only when dual-port functionality is unnecessary and higher density at lower voltage is prioritized over real-time synchronization features. |
Compared with CY7C028V-20AC and IS61LV25616AL-10TLI, the 5962-9150801MXA uniquely delivers military-qualified dual-port operation with hardware arbitration, 2 V data retention, and 68-pin PGA packaging-making it irreplaceable in safety-critical, temperature-extreme, or legacy 5 V systems where deterministic contention resolution is mandatory.

FAQ
What is the maximum operating temperature range certified for the 5962-9150801MXA?
The 5962-9150801MXA is fully qualified per MIL-PRF-38535 Class B for continuous operation from –55°C to +125°C. This rating is verified through temperature cycling, burn-in, and parametric testing across the full range-not just derated or characterized. The 5962-9150801MXA maintains specified 20 ns access time and functional integrity throughout this military temperature envelope.
Does the 5962-9150801MXA support battery backup for data retention, and what voltage is required?
Yes, the 5962-9150801MXA supports data retention at 2.0 V minimum (VDR), enabling operation from a backup lithium battery or supercapacitor during main power loss. This feature is explicitly guaranteed for the L-version variant and validated across the full military temperature range. The 5962-9150801MXA retains valid data indefinitely at 2 V with ICCDR ≤ 4000 µA (max) under worst-case conditions.
How does the BUSY arbitration mechanism work in the 5962-9150801MXA during simultaneous port access?
The 5962-9150801MXA uses hardware arbitration: when both ports attempt access to the same address, the BUSY flag asserts within tBAA (≤20 ns) on the contending port. If configured as Master (M/S = H), BUSY is driven high; if Slave (M/S = L), BUSY is sampled as input. The tBDD parameter (≤30 ns) defines the delay from BUSY deassertion to valid read data, ensuring deterministic resolution without software intervention.
Can the 5962-9150801MXA be used in a 16-bit data path configuration, and how is that implemented?
Yes-the 5962-9150801MXA supports 16-bit expansion via Master/Slave cascading. Two devices are connected with M/S = H on one (Master) and M/S = L on the other (Slave); BUSY outputs chain to BUSY inputs, and CE/R/W/OE signals are shared. The 5962-9150801MXA's internal logic ensures synchronized operation without external arbitration logic, enabling full-speed 16-bit word access.
What package type is used for the 5962-9150801MXA, and are there lead-free options?
The 5962-9150801MXA is supplied exclusively in a hermetic 68-pin ceramic Pin Grid Array (PGA) package, per MIL-STD-883 requirements. This package provides superior thermal dissipation, moisture resistance, and mechanical robustness for military use. Lead-free versions are not offered; the device complies with RoHS exemptions for high-reliability military applications under EU Directive 2011/65/EU Annex III.
