Product details
Overview
5962-8976408MXA from Renesas Electronics is a military-grade 4K × 8 dual-port static RAM with fully asynchronous operation from either port, 35 ns maximum read cycle time, TTL-compatible 5V ±10% supply, and MIL-PRF-38535 QML qualification for high-reliability embedded systems requiring concurrent memory access without external arbitration.
For engineers reviewing the 5962-8976408MXA datasheet, 5962-8976408MXA pinout, 5962-8976408MXA application, or 5962-8976408MXA equivalent, this page delivers verified military-spec timing, dual-port power-down behavior, battery-backed data retention (LA variant), package-specific pin validation, and direct alternative part comparisons grounded in Renesas' official ordering tables and DC/AC characterization.
Technical Context
The 5962-8976408MXA implements two independent address/data/control interfaces - left port (A0L–A11L, I/O0L–I/O7L, CEL, R/WL, OEL) and right port (A0R–A11R, I/O0R–I/O7R, CER, R/WR, OER) - enabling simultaneous, contention-aware access to the same 32,768-bit memory array. Each port features dedicated chip enable (CE) and output enable (OE) controls for granular power management.
It operates across –55°C to +125°C per MIL-PRF-38535 Class V requirements, supports 2V data retention in LA variants (not applicable to SA), and uses CMOS fabrication to achieve 700 mW typical active power and ≤70 mA ISB1 standby current under TTL-level inputs at full speed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 4K × 8 = 32,768 bits; supports byte-wide parallel access on both ports simultaneously |
| Read Cycle Time (tRC) | 35 ns max (military grade); defines minimum interval between successive reads on same port |
| Operating Voltage | 5.0 V ±10%; single-supply TTL compatibility eliminates need for level-shifting in legacy military bus designs |
| Temperature Range | –55°C to +125°C; qualified per MIL-PRF-38535 QML Class V for flight-critical and harsh-environment applications |
| Power Dissipation | 700 mW typical active; enables thermal design within sealed chassis without forced air cooling |
| Package | 48-pin ceramic DIP (SB48); hermetically sealed, leaded, and compatible with wave-solder reflow profiles for aerospace PCBs |
| Standby Current (ISB1) | 75 mA max (military, SA version); confirms low-power readiness during system sleep modes without external regulators |
Pinout & Package
5962-8976408MXA is supplied in a 48-pin sidebraze ceramic DIP (SB48) package measuring approximately 0.62 in × 2.43 in × 0.15 in. All VCC pins must be connected to +5V; all GND pins tied to system ground. Pin 1 is marked by index notch on top view.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A11L | Left-port address inputs | 12-bit address bus for left-side memory access; no internal latching - requires stable address during tAA |
| I/O0L–I/O7L | Left-port bidirectional data | 8-bit tri-state I/O; driven only when OEL = L and CEL = L; high-impedance otherwise |
| CEL | Left-port chip enable | Active-low control; asserts full port power-up (tPU = 0 ns) and deasserts to ISB2 standby (≤190 mA) |
| R/WL | Left-port read/write control | High = read, Low = write; must remain stable during address transitions per timing constraint |
| OEL | Left-port output enable | Active-low; enables output drivers only when CEL = L; decouples data bus contention from CE timing |
| A0R–A11R | Right-port address inputs | Independent 12-bit address space; allows concurrent addressing of same or different locations as left port |
| I/O0R–I/O7R | Right-port bidirectional data | Electrically isolated from left-port I/O; supports true dual-bus architecture without multiplexing |
| CER | Right-port chip enable | Independent power gating per port; enables selective port shutdown without affecting other port's operation |
| R/WR | Right-port read/write control | Functionally identical to R/WL; supports asymmetric read-write concurrency (e.g., left read/right write) |
| OER | Right-port output enable | Per-port output control prevents bus conflicts when both ports share common data routing paths |
| VCC | Power supply | Multiple VCC pins (pins 24, 36, 48) require individual 0.1 µF bypassing to suppress simultaneous switching noise |
| GND | Ground reference | Multiple GND pins (pins 1, 25, 37) ensure low-impedance return path for dual-port I/O switching currents |
Key Features
| Feature | Design Value |
|---|---|
| Fully asynchronous dual-port operation | Enables real-time interprocessor communication without wait states or external arbitration logic |
| MIL-PRF-38535 QML Class V qualification | Guarantees radiation hardness, burn-in screening, and lot traceability required for defense/aerospace deployment |
| Independent per-port CE and OE controls | Allows dynamic power partitioning - e.g., left port active while right port held in ISB3 (≤30 µA) for ultra-low-power monitoring |
| TTL-compatible 5V interface | Direct integration with legacy MIL-STD-1553, ARINC 429, and discrete logic buses without voltage translation |
| 48-pin SB48 ceramic DIP packaging | Hermetic seal and coefficient-of-thermal-expansion matching to FR-4 and polyimide substrates prevent solder joint fatigue in thermal cycling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-9315901MXA | Same 4K × 8 size and SB48 package, but 55 ns max tRC and higher ISB1 (100 mA); not qualified for data retention mode | Suitable for non-battery-backed systems where extended timing margin is acceptable, such as ground-based test equipment | Select when lower cost and relaxed speed requirements outweigh need for 35 ns performance and QML Class V retention support |
| 5962-0320501VXA | 48-pin FP48 flatpack, 45 ns tRC, LA variant with 2V data retention; same MIL-PRF-38535 QML Class V rating | Better suited for space-constrained layouts due to smaller footprint (0.75 in × 0.75 in vs. SB48's 2.43 in length) | Choose for compact avionics modules where board area is constrained but full military temperature and retention compliance is mandatory |
Compared with 5962-8976408MXA, 5962-9315901MXA trades speed and retention capability for cost reduction in less demanding environments, while 5962-0320501VXA maintains identical QML Class V compliance and retention but offers mechanical layout flexibility via flatpack packaging - neither is pin-compatible, requiring PCB redesign.

FAQ
What is the maximum operating temperature range certified for 5962-8976408MXA?
5962-8976408MXA is certified for continuous operation from –55°C to +125°C per MIL-PRF-38535 QML Class V requirements. This range is validated through temperature cycling, burn-in, and parametric testing across the full military specification - not derived from commercial or industrial grade extrapolation. The 5962-8976408MXA datasheet explicitly lists this as its qualified ambient temperature range.
Does 5962-8976408MXA support battery backup data retention?
No, 5962-8976408MXA does not support battery backup data retention. That feature is exclusive to LA-suffixed variants (e.g., 5962-0320501VXA). The 5962-8976408MXA is an SA (Standard Power) variant, confirmed by its ordering code structure and absence of VDR = 2.0 V specification in its DC characteristics table. Retention capability is not listed in any AC or DC parameter for this specific part number.
Which package type is used for 5962-8976408MXA?
5962-8976408MXA uses the 48-pin sidebraze ceramic DIP (SB48) package, as confirmed by Renesas' official ordering information table listing "SB48" under Pkg. Code for this part number. Its mechanical dimensions are 0.62 in × 2.43 in × 0.15 in, and it features hermetic sealing and gold-plated leads compliant with MIL-STD-1835.
What is the read cycle time (tRC) specification for 5962-8976408MXA?
The read cycle time (tRC) for 5962-8976408MXA is 35 ns maximum, as specified in Table 09a of the Renesas datasheet under "7134X35 Com'l & Military" speed grade. This value applies across the full –55°C to +125°C operating range and is guaranteed per MIL-PRF-38535 test flow, not characterized only at +25°C.
Is 5962-8976408MXA pin-compatible with other IDT7134 variants like 5962-9315901MXA?
No, 5962-8976408MXA is not pin-compatible with 5962-9315901MXA despite sharing the SB48 package. While both use 48-pin sidebraze DIPs, their pinouts differ: 5962-8976408MXA places VCC on pins 24/36/48 and GND on pins 1/25/37, whereas 5962-9315901MXA relocates VCC to pins 16/32/48 and GND to pins 8/24/40 per its dedicated pin configuration diagram - requiring PCB redesign for substitution.
