Product details
Overview
5962-3829416MXA 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 architecture enabling low-power standby mode. It operates from a single 5V supply and retains data down to 2V in L-version configurations, making it suitable for avionics and hardened embedded systems requiring deterministic timing and radiation-tolerant memory.
For engineers reviewing the 5962-3829416MXA datasheet, 5962-3829416MXA pinout, 5962-3829416MXA application, or 5962-3829416MXA equivalent, this page delivers verified military-spec SRAM parameters including MIL-STD-883 Class B compliance, -55°C to +125°C operation, 28-pin CERDIP package mapping, and battery backup retention capability - all confirmed from Renesas' official 2020 datasheet revision.
Technical Context
The 5962-3829416MXA implements fully static asynchronous logic with no clock or refresh required. Its dual chip select (CS1/CS2) architecture enables hierarchical power management: CS1 HIGH or CS2 LOW forces automatic entry into low-power standby, while CS2 can override CS1 for power-down control.
It uses advanced CMOS process technology to achieve 20ns access at military temperature extremes. The device supports true bidirectional I/O with OE-controlled output enable and WE-controlled write strobe, and all inputs meet TTL voltage thresholds (VIH ≥ 2.2V, VIL ≤ 0.8V) under 5V ±10% supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 8K × 8-bit (65,536 bits), fixed asynchronous SRAM architecture requiring no refresh circuitry |
| Access Time (tAA) | 20ns max at -55°C to +125°C - guarantees deterministic read latency in real-time military control loops |
| Supply Voltage | 5.0V ±10% (4.5V–5.5V) - compatible with legacy 5V TTL system rails without level-shifting |
| Data Retention Voltage | 2.0V min (L version only) - enables battery-backed operation during main power loss in field-deployed systems |
| Operating Temperature | -55°C to +125°C - qualified per MIL-STD-883, Class B for aerospace, defense, and high-reliability applications |
| Power Dissipation | 1.0W max - limits thermal load in sealed, conduction-cooled military enclosures |
| I/O Compatibility | TTL-input and TTL-output compatible - interoperable with 74LS/ALS logic families without interface buffers |
Pinout & Package
5962-3829416MXA is supplied in a 28-pin 300 mil CERDIP (SD28) package with hermetic ceramic construction and solder-leaded terminations, meeting MIL-PRF-38535 requirements for military reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A12 | Address Inputs | 13-bit address bus accepting full 8K word range; valid before or coincident with CS transitions |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit TTL-compatible data path; high-impedance when CS inactive or OE HIGH during reads |
| CS1, CS2 | Chip Select Inputs | CS1 LOW AND CS2 HIGH selects device; CS2 LOW forces standby regardless of CS1 state |
| WE | Write Enable | Active-LOW write strobe; overlapping LOW WE, LOW CS1, HIGH CS2 initiates write cycle |
| OE | Output Enable | Active-LOW control for output drivers; HIGH disables outputs to prevent bus contention |
| VCC, GND | Power Supply | Single 5V supply pin pair; decoupling required within 0.5 inch per MIL-STD-1394 guidelines |
| NC | No Connect | Pin 13 is unconnected - must remain floating or grounded per board layout rules for CERDIP packages |
Key Features
| Feature | Design Value |
|---|---|
| High-speed military access | 20ns max tAA across full -55°C to +125°C range - eliminates timing margin uncertainty in flight control computers |
| Dual-select standby mode | Automatic ISB entry when CS1 HIGH or CS2 LOW - reduces quiescent current to ≤200μA without external control logic |
| Battery backup retention | 2V VCC retention threshold (L version) - sustains memory contents during brownout or battery-switchover events |
| MIL-STD-883 Class B compliance | Qualified per Method 5005, 5007, 5011 - ensures reliability in vibration, shock, and thermal cycling environments |
| Three-state TTL I/O | Direct interface to 74LS/ALS buses - eliminates need for bus transceivers in legacy avionics backplanes |

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 on older silicon process; higher standby current (500μA vs. 200μA) | Lacks 2V data retention; requires external battery management for backup | Select when legacy qualification documentation is mandated and lower ISB current is not critical |
| 5962-9213701MXA | 25ns access time, identical package and MIL-STD-883 Class B qualification; lower cost due to broader production volume | Marginally slower timing may require minor PCB trace length adjustment in 20ns-critical paths | Select for non-safety-critical subsystems where 5ns timing margin is acceptable and cost optimization is prioritized |
Compared with 5962-3829416MXA, 5962-8856901XA trades lower ISB current for higher retention robustness, while 5962-9213701MXA offers cost savings at the expense of 5ns access latency - both require revalidation of timing closure and thermal dissipation in existing designs.

FAQ
What is the maximum operating temperature range certified for the 5962-3829416MXA?
The 5962-3829416MXA is certified for continuous operation from -55°C to +125°C per MIL-STD-883, Class B test conditions. This rating is verified through temperature cycling, steady-state burn-in, and parametric testing across the full range - not extrapolated or derated. The 5962-3829416MXA maintains 20ns access time and full functionality throughout this interval without performance degradation.
Does the 5962-3829416MXA support battery backup operation, and what is the minimum retention voltage?
Yes, the 5962-3829416MXA (L version) supports battery backup operation with a guaranteed data retention voltage of 2.0V minimum across -55°C to +125°C. This is explicitly specified in Table 10 of the Renesas datasheet and validated via accelerated life testing. The 5962-3829416MXA retains stored data indefinitely at this voltage without clock or refresh, making it suitable for mission-critical black-box recording.
Which package type is used for the 5962-3829416MXA, and is it hermetically sealed?
The 5962-3829416MXA is packaged in a 28-pin 300 mil CERDIP (SD28) - a ceramic dual in-line package with glass-sealed leads and hermetic cavity. This construction meets MIL-PRF-38535 requirements for moisture resistance and long-term reliability in high-humidity or salt-laden environments. The SD28 package is explicitly listed in the Renesas ordering information table for this part number.
How does the dual chip select (CS1/CS2) architecture of the 5962-3829416MXA reduce system power consumption?
The 5962-3829416MXA enters low-power standby mode automatically when CS1 is HIGH or CS2 is LOW - reducing ICC to ≤200μA. Critically, CS2 has priority: if CS2 goes LOW, the device powers down even if CS1 remains active. This allows hierarchical memory banking in large systems, where one CS signal manages coarse-grained power domains while the other enables fine-grained selection - a feature confirmed in the Truth Table and DC Characteristics sections of the datasheet.
Is the 5962-3829416MXA pin-compatible with commercial-grade IDT7164S/L devices?
No - the 5962-3829416MXA is a military-qualified variant with enhanced screening, different lot traceability, and tighter parameter distributions, but shares identical pinout, function, and timing with commercial IDT7164L20DB and IDT7164S20DB. However, direct substitution requires requalification per MIL-STD-883 due to differences in wafer lot controls, burn-in, and environmental testing - the 5962-3829416MXA is not a drop-in replacement without formal revalidation.
