Product details
Overview
5962-3829406MXA from Renesas Electronics is a military-grade 64K (8K × 8-bit) CMOS static RAM with 20ns maximum address access time, TTL-compatible I/O, three-state outputs, and dual chip select (CS1/CS2) for low-power standby mode. It operates from a single +5V supply and supports battery backup data retention down to 2V (L-version). It is used in avionics, radar processors, and hardened embedded systems requiring high reliability under extreme temperature cycling.
For engineers reviewing the 5962-3829406MXA datasheet, 5962-3829406MXA pinout, 5962-3829406MXA application, or 5962-3829406MXA equivalent, key selection criteria include military-grade MIL-STD-883 Class B compliance, -55°C to +125°C operating range, 28-pin CERDIP package, 20ns speed grade, and CS-controlled power-down behavior - all critical for DO-254/DO-160G-certified designs.
Technical Context
The 5962-3829406MXA implements fully static asynchronous operation with no clock or refresh required. Its dual chip select architecture enables precise control of standby entry: CS1 HIGH or CS2 LOW forces automatic transition into low-power ISB mode, while CS2 can override CS1 for guaranteed power-down.
It uses advanced CMOS process technology to achieve 20ns access at full military temperature range (-55°C to +125°C), with input/output voltage thresholds (VIH = 2.2V min, VIL = 0.8V max) and output drive capability (IOL = 8mA, VOH = 2.4V min) fully specified across that range. Data retention at 2V is exclusive to the L-version and validated per MIL-STD-883 Method 1017.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64K-bit (8K × 8-bit) - provides byte-wide data interface compatible with 8-bit microprocessors and bus architectures. |
| Access Time (tAA) | 20ns max at -55°C to +125°C - ensures deterministic timing margin for real-time signal processing in radar front-ends. |
| Supply Voltage | +5.0V ±10% - simplifies power design with single-rail support and eliminates need for auxiliary bias supplies. |
| Operating Temperature | -55°C to +125°C - qualified per MIL-STD-883 Class B, enabling deployment in jet engine-mounted controllers and space-qualified payloads. |
| Standby Current (ISB) | 2mA max at +125°C - enables ultra-low quiescent power during dormant phases in battery-backed mission-critical systems. |
| Data Retention Voltage | 2.0V min (L-version only) - allows sustained memory hold during brown-out or primary power failure without external backup circuitry. |
| Package | 28-pin 600-mil CERDIP (CD28) - hermetically sealed ceramic package with proven long-term reliability in high-humidity, high-vibration environments. |
Pinout & Package
5962-3829406MXA is supplied in a 28-pin 600-mil ceramic dual in-line package (CERDIP), designated CD28 per Renesas ordering nomenclature. This hermetic package meets MIL-STD-883 requirements for moisture resistance, thermal shock, and mechanical robustness in aerospace applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A12 | Address Inputs | 13-bit address bus accepting full 8K-word range; TTL-compatible thresholds ensure direct interfacing with legacy 8085/8086-family CPUs. |
| I/O0–I/O7 | Bi-directional Data Bus | 8-bit TTL-compatible data path with three-state outputs; high-impedance state activated when CS1 HIGH or CS2 LOW. |
| CS1, CS2 | Chip Select Inputs | Dual active-Low/active-High selects enable hierarchical memory mapping; CS2 LOW forces standby regardless of CS1 state. |
| WE | Write Enable | Active-Low control for write cycles; combined with CS1/CS2, defines valid write window per MIL-STD-883 timing diagrams. |
| OE | Output Enable | Active-Low control for read data output; independent of CS1/CS2, allowing output gating during partial decode conditions. |
| VCC, GND | Power Supply | Single +5V supply with dedicated ground pin; decoupling required per MIL-STD-883 test condition 301.1 for transient immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Fully static operation | No clocks or refresh required - eliminates timing-critical refresh circuitry and reduces system-level jitter in deterministic real-time systems. |
| Dual chip select with priority logic | CS2 LOW overrides CS1 to guarantee standby entry - enables fail-safe power management in fault-tolerant architectures. |
| TTL-compatible I/O | Direct interface with legacy 5V logic families without level-shifting - preserves signal integrity and reduces BOM count in retrofitted military platforms. |
| MIL-STD-883 Class B qualification | Full screening including burn-in, thermal cycling, and hermeticity testing - satisfies DO-254 hardware assurance level HDAL for airborne systems. |
| Battery backup data retention (L-version) | Validated 2V hold capability across -55°C to +125°C - supports uninterrupted memory state during extended power loss in missile guidance subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8856901XA | Same 8K×8 organization and 20ns speed, but fabricated by Texas Instruments; uses 28-pin CERDIP (CD28) and qualifies to MIL-STD-883 Class B, yet lacks 2V data retention capability. | Applicable where battery backup is not required, such as in non-redundant telemetry buffers with continuous primary power. | Select 5962-8856901XA only if data retention below 4.5V is unnecessary and TI's qualification documentation satisfies program-specific acceptance criteria. |
| 5962-9213701M2X | 64K-bit SRAM with 25ns access, manufactured by Micross; offered in 28-pin CERDIP and screened to MIL-STD-883 Class B, but specifies only 4.5V minimum retention voltage. | Suitable for mid-tier military platforms where 25ns timing margin is acceptable and extended low-voltage hold is not mandated by system safety analysis. | Choose 5962-9213701M2X when cost sensitivity outweighs the need for sub-4.5V retention, and when procurement lead times for Renesas devices exceed program schedule windows. |
Compared with 5962-3829406MXA, 5962-8856901XA omits battery backup functionality entirely, while 5962-9213701M2X requires ≥4.5V for data retention - making 5962-3829406MXA the sole option among these three for systems demanding guaranteed 2V hold across full military temperature range.

FAQ
What is the maximum operating temperature range certified for the 5962-3829406MXA?
The 5962-3829406MXA is fully qualified for operation from -55°C to +125°C per MIL-STD-883 Class B test requirements. All AC and DC parameters - including 20ns access time, 2mA standby current, and 2V data retention - are guaranteed across this full range, with test reports available upon request for DO-254 compliance packages.
Does the 5962-3829406MXA require an external clock or refresh circuit?
No, the 5962-3829406MXA uses fully static CMOS architecture and requires no clock signal or periodic refresh cycles. This eliminates timing-critical support circuitry and makes it ideal for deterministic real-time systems such as flight control computers where jitter-free memory access is essential.
Is the 2V data retention feature available on all versions of the 5962-3829406MXA?
No - the 2V data retention capability is exclusive to the "L" (low-power) version of the device, which is explicitly designated in the part number suffix. The 5962-3829406MXA is an L-version part, and its 2V retention is verified per MIL-STD-883 Method 1017 across the full -55°C to +125°C range.
What package type does the 5962-3829406MXA use, and is it hermetically sealed?
The 5962-3829406MXA uses a 28-pin 600-mil ceramic dual in-line package (CERDIP), identified as CD28 in Renesas ordering nomenclature. It is hermetically sealed per MIL-STD-883 requirements, providing proven resistance to moisture, thermal shock, and outgassing in vacuum and high-humidity environments.
How does the dual chip select (CS1/CS2) architecture improve power management in the 5962-3829406MXA?
The 5962-3829406MXA's CS1/CS2 logic enables hierarchical power control: CS1 HIGH or CS2 LOW forces immediate entry into low-power standby mode (ISB), and CS2 LOW takes precedence over CS1. This allows system designers to implement fail-safe power-down sequences - for example, asserting CS2 during brown-out detection to guarantee memory retention without relying on software-controlled CS1 assertion.
