Product details
Overview
5962-8976408MYA 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 5 V ±10% supply, and MIL-PRF-38535 QML compliance for high-reliability embedded systems requiring concurrent memory access in avionics or radar signal processing.
For engineers reviewing the 5962-8976408MYA datasheet, 5962-8976408MYA pinout, 5962-8976408MYA application, or 5962-8976408MYA equivalent, this page delivers verified military-spec timing, dual-port arbitration behavior, battery backup capability (LA variant), package-specific pin validation, and direct alternatives for legacy system sustainment and radiation-tolerant design reuse.
Technical Context
The 5962-8976408MYA implements two independent address/data/control interfaces (left/right ports) with separate CE, OE, R/W, and address buses-enabling simultaneous but externally arbitrated access to the same 32 Kbit memory array. It lacks on-chip arbitration logic, placing contention resolution responsibility on the system designer.
It supports full standby modes via CMOS-level CE control (ISB3 ≤ 0.2 mA typ. for LA), retains data down to 2 V (LA only), and operates across −55°C to +125°C per MIL-PRF-38535 Class B requirements. Fabricated in high-performance CMOS, it delivers 700 mW typical active power at 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 4K × 8 = 32 Kbit; supports byte-wide parallel data paths on both ports without multiplexing. |
| Access Time | 35 ns max (tRC); enables real-time buffering in 28 MHz synchronous systems with zero wait states. |
| Supply Voltage | 5.0 V ±10%; compatible with legacy TTL logic families and military power distribution rails. |
| Operating Temp | −55°C to +125°C; qualified per MIL-PRF-38535 QML Class B for flight-critical hardware deployment. |
| Standby Current | 0.2 mA typ. (ISB3, LA); allows battery-backed retention during extended system sleep without external regulators. |
| Package | 48-pin ceramic DIP (SB48); hermetically sealed, leaded, and qualified for high-vibration aerospace environments. |
| Data Retention | 2 V minimum (LA only); sustains memory state during brownout or primary power loss in mission-critical systems. |
Pinout & Package
5962-8976408MYA is supplied in a 48-pin sidebraze ceramic DIP (SB48) package, measuring approximately 0.62 in × 2.43 in × 0.15 in, with gold-plated leads and hermetic sealing suitable for military and space applications.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A11L | Left port address inputs | 12-bit address bus for left-side memory access; must be stable before CE/L assertion. |
| A0R–A11R | Right port address inputs | Independent 12-bit address bus; enables concurrent addressing of same or different locations. |
| I/O0L–I/O7L | Left port bidirectional data | 8-bit data path; direction controlled by R/WL and OEL; high-impedance when deselected. |
| I/O0R–I/O7R | Right port bidirectional data | Electrically isolated 8-bit path; no internal bus contention-external arbitration required. |
| CEL, CER | Chip enable (left/right) | Active-low enables respective port; drives ISB2/ISB4 standby current when high. |
| OEL, OER | Output enable (left/right) | Active-low controls output drivers; high-Z when disabled, preserving bus integrity. |
| R/WL, R/WR | Read/write control (left/right) | Active-low write strobe; determines data flow direction on I/O pins during CE assertion. |
| VCC, GND | Power and ground | All VCC and GND pins must be connected; decoupling required per MIL-STD-1399. |
Key Features
| Feature | Design Value |
|---|---|
| Fully asynchronous dual-port interface | Enables deterministic, non-blocking memory access from two independent processors or DMA engines without clock synchronization. |
| Battery backup data retention (LA variant) | Maintains stored data at 2 V supply-critical for fault-tolerant systems requiring persistent state after main power failure. |
| MIL-PRF-38535 QML Class B qualification | Guarantees screening, testing, and traceability per U.S. DoD requirements for high-reliability defense electronics. |
| Low-power standby modes | ISB3 ≤ 0.2 mA (LA) reduces system-level quiescent power-essential for battery-operated or thermally constrained platforms. |
| TTL-compatible signaling | Direct interface with legacy 5 V logic families (e.g., LS, ALS) without level-shifting circuitry. |

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 architecture, 45 ns max tRC, SB48 package, but SA (standard power) variant; no 2 V data retention. | Lacks battery backup-suitable for non-critical buffers where power interruption is not mission-degrading. | Select when lower cost and higher speed margin are prioritized over data retention during brownout. |
| 5962-0151501VXA | 48-pin FP48 flatpack; identical 35 ns timing and LA power spec, but different mechanical footprint and thermal profile. | Used in PCB layouts requiring low-profile mounting and improved thermal conduction to chassis. | Choose for space-constrained avionics modules where height < 0.12 in is mandatory per AS9100 mechanical specs. |
Compared with 5962-8976408MYA, 5962-9315901MXA trades data retention for faster access and lower procurement risk, while 5962-0151501VXA offers identical electrical performance in a lower-profile flatpack-both require layout revision but preserve functional compatibility in QML-compliant designs.

FAQ
What is the operating temperature range certified for 5962-8976408MYA?
5962-8976408MYA is certified for −55°C to +125°C ambient operation per MIL-PRF-38535 Class B requirements. This range is validated through temperature cycling, burn-in, and parametric testing across the full interval-not extrapolated or derated. The device maintains 35 ns access time and full functionality throughout this range, with no additional derating needed for flight-critical deployment.
Does 5962-8976408MYA support battery backup data retention?
Yes, 5962-8976408MYA is the LA (low-power) variant and supports data retention at VCC ≥ 2.0 V, as specified in Table 2720 tbl 07. This feature enables sustained memory state during brownout or primary power loss-critical for cryptographic key preservation and fault recovery in defense systems.
Which package type is used for 5962-8976408MYA?
5962-8976408MYA uses the 48-pin sidebraze ceramic DIP (SB48) package, with dimensions approximately 0.62 in × 2.43 in × 0.15 in. This hermetically sealed, leaded package meets MIL-STD-883 requirements for mechanical robustness, thermal cycling, and long-term reliability in high-vibration aerospace environments.
How does arbitration work between the two ports of 5962-8976408MYA?
5962-8976408MYA provides no on-chip arbitration logic. When both ports simultaneously access the same memory location, contention must be resolved externally-via discrete logic, FPGA-based arbiter, or system-level protocol. The device outputs reflect last-write-wins behavior, and data integrity is the user's responsibility per datasheet Section "Functional Description".
Is 5962-8976408MYA compliant with MIL-PRF-38535?
Yes, 5962-8976408MYA is manufactured and tested in full compliance with MIL-PRF-38535 QML Class B, including screening, lot acceptance testing, and traceability documentation.
