Product details
Overview
5962-3829408MXA 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 battery backup data retention down to 2V (L-version). It operates from a single 5V supply and supports standby power reduction via dual chip select control (CS1/CS2), making it suitable for avionics, radar signal buffering, and secure embedded systems requiring MIL-STD-883 Class B compliance.
For engineers reviewing the 5962-3829408MXA datasheet, 5962-3829408MXA pinout, 5962-3829408MXA application, or 5962-3829408MXA equivalent, this page delivers verified timing parameters, military temperature range validation (–55°C to +125°C), package-specific pin mapping for 28-pin CERDIP, DC/AC electrical characteristics per MIL-STD-883, and direct alternative part guidance aligned with Renesas' official orderable IDT7164L20DB lineage.
Technical Context
The 5962-3829408MXA implements fully static asynchronous architecture-no clocks or refresh required-and uses dual chip select logic where CS2 powers down CS1 but not vice versa. Its low-power standby mode activates when CS1 is HIGH or CS2 is LOW, reducing ICCSB to 2mA max (military grade).
It features TTL-compatible input thresholds (VIH = 2.2V min, VIL = 0.8V max), output drive capability of IOH = –4mA / IOL = 8mA, and data retention at VCC ≥ 2.0V with ICCDR ≤ 300μA across full military temperature range, validated per MIL-STD-883 test method 1017.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 8K × 8-bit (65,536 bits), byte-wide parallel interface |
| Access Time (tAA) | 20ns max (military grade, –55°C to +125°C), enabling 50MHz burst read cycles |
| Supply Voltage | 5.0V ±10% (4.5V–5.5V), single-rail operation simplifies power design |
| Operating Temperature | –55°C to +125°C, qualified per MIL-STD-883 Class B screening |
| Standby Current (ISB) | 2.0mA max (military), achieved via CS1/CS2-controlled automatic low-power mode |

| CS2 | Chip Select 2 | Active-HIGH secondary enable; powers down device if driven LOW (overrides CS1) |
| WE | Write Enable | Active-LOW control for write cycles; must be LOW concurrently with active CS1/CS2 |
| OE | Output Enable | Active-LOW control for read data output; disabled (high-Z) when HIGH or during write |
| VCC | Power Supply | +5V ±10% supply pin; decoupling required within 0.5 inch per MIL-STD-883 |
| GND | Ground Reference | Signal and power ground common return; requires low-inductance PCB connection |
| NC | No Connect | Pin 13 is unconnected; must remain floating per Renesas design specification |

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 ISB (5mA vs. 2mA) | Lacks guaranteed 2V data retention; limited to non-battery-backed use cases | Select when cost sensitivity outweighs standby power or retention voltage requirements |
| 5962-9213701M2X | 25ns access time, identical CERDIP package and MIL-STD-883 Class B qualification | Lower performance margin; unsuitable for 50MHz-critical timing paths | Choose for legacy system drop-in replacement where 20ns timing is not required |
Compared with 5962-3829408MXA, 5962-8856901XA trades lower standby current and 2V retention for higher cost and obsolescence risk, while 5962-9213701M2X offers proven field reliability at reduced speed-making the original optimal for new designs demanding both performance and battery backup.

FAQ
What is the maximum operating temperature range certified for 5962-3829408MXA?
The 5962-3829408MXA is certified for continuous operation from –55°C to +125°C per MIL-STD-883 Class B testing, including thermal cycling, steady-state life, and burn-in. This range is explicitly validated in the Renesas datasheet revision Jul.30.20 and confirmed by its orderable IDT7164L20DB heritage. No derating is required within this envelope for 5962-3829408MXA.
Does 5962-3829408MXA support true battery backup operation?
Yes, 5962-3829408MXA is the L-version variant and supports data retention at VCC ≥ 2.0V, as specified in Table 10 (Data Retention Characteristics). This capability is exclusive to L-grade parts and enables reliable memory hold during main power failure-critical for mission-critical systems where battery-backed state preservation is mandated.
Is 5962-3829408MXA pin-compatible with commercial-grade IDT7164S20YG?
No-5962-3829408MXA uses a 28-pin 600-mil CERDIP (CD28) package, while IDT7164S20YG uses a 28-pin 300-mil SOJ (PJG28). Pin numbering and physical dimensions differ; PCB layout redesign and socket replacement are required. Electrical pin functions match, but mechanical compatibility does not exist.
What is the standby current specification for 5962-3829408MXA under military conditions?
The standby current (ISB) for 5962-3829408MXA is guaranteed ≤ 2.0mA maximum across –55°C to +125°C when CS1 is HIGH or CS2 is LOW, per Table 7 (DC Electrical Characteristics, MIL column). This value reflects worst-case characterization and is production-tested per MIL-STD-883 Method 3001.
Which chip select combination places 5962-3829408MXA into low-power standby mode?
5962-3829408MXA enters low-power standby when either CS1 is driven HIGH or CS2 is driven LOW-per Truth Table 2 and functional description. CS2 has priority: if CS2 is LOW, the device remains in standby regardless of CS1 state. This dual-control mechanism allows flexible power sequencing in complex military subsystems.
