Product details
Overview
5962-3829410MZA 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 processors, and hardened embedded systems requiring non-volatile memory persistence during brownout.
For engineers reviewing the 5962-3829410MZA datasheet, 5962-3829410MZA pinout, 5962-3829410MZA application, or 5962-3829410MZA equivalent, this page delivers verified timing specs (tAA = 20ns), military temperature compliance (–55°C to +125°C), MIL-STD-883 Class B qualification, DIP/SOJ package mapping, and direct alternatives for legacy SRAM replacement in defense electronics design.
Technical Context
The 5962-3829410MZA implements fully static asynchronous operation-no clocks or refresh required-and uses dual chip select logic where CS2 powers down CS1 but not vice versa. Its low-power (L) variant enables data retention at VCC ≥ 2.0V while drawing ≤200μA in retention mode across full military temperature range.
Input and output pins are TTL-compatible (VIH = 2.2V min, VOL = 0.4V max at IOL = 8mA), and all DC/AC parameters-including tRC, tWC, tOHZ, and tCLZ-are guaranteed over –55°C to +125°C per MIL-STD-883 Class B test flow. Standby current ISB is specified at 2mA max (S-version) and 1mA max (L-version) under full military conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8763301XA | Same 8K×8 organization, 25ns tAA, CD28 CERDIP, but no battery backup (S-version only) | Lacks 2V data retention; requires external backup circuitry for brownout resilience | Select when cost sensitivity outweighs retention requirement and 25ns timing suffices |
| 5962-9213901MXA | 28-pin SOJ (PJG28), 20ns tAA, L-version with 2V retention, but rated only to –55°C to +105°C | SOJ package offers smaller footprint but lower thermal mass and no hermetic seal | Choose for space-constrained designs where full +125°C operation is not required |
Compared with 5962-3829410MZA, 5962-8763301XA trades retention capability for broader commercial availability, while 5962-9213901MXA sacrifices military-grade thermal range for surface-mount flexibility-neither is pin-compatible, requiring PCB redesign for substitution.

FAQ
What is the guaranteed access time for 5962-3829410MZA across its full military temperature range?
The 5962-3829410MZA guarantees a maximum address access time (tAA) of 20ns over the full –55°C to +125°C operating range, as validated per MIL-STD-883 Class B test conditions. This specification applies to both read and write cycle initiation and is production-tested-not characterized-only-ensuring deterministic timing in real-time defense systems where jitter or variation cannot be tolerated. The 20ns value is maintained independent of VCC variation within 5.0V ±10%.
Does 5962-3829410MZA support true battery backup operation, and what is the minimum voltage required?
Yes, 5962-3829410MZA (L-version) supports true battery backup operation with guaranteed data retention at VCC ≥ 2.0V across –55°C to +125°C. This is confirmed in Table 10 of the Renesas datasheet (VDR = 2.0V min), and the device draws ≤200μA in retention mode. The feature eliminates need for external backup capacitors or supercapacitor circuits in brownout-prone platforms such as missile guidance subsystems.
Is 5962-3829410MZA pin-compatible with other IDT7164 variants like 7164S20DB or 7164L20DB?
Yes, 5962-3829410MZA shares identical pinout, electrical interface, and functional behavior with commercial/industrial IDT7164S/L variants in the same CD28 CERDIP package-including 7164S20DB and 7164L20DB. All use the same 28-pin layout, TTL-compatible signaling, and dual CS architecture. However, 5962-3829410MZA adds mandatory MIL-STD-883 Class B screening and extended temperature validation not present in non-5962 versions.
What package type is used for 5962-3829410MZA, and does it meet hermeticity requirements?
5962-3829410MZA is packaged in a 28-pin 600-mil CERDIP (CD28) housing, which is a hermetically sealed ceramic dual in-line package qualified to MIL-PRF-38535. It meets stringent moisture resistance, leak rate (<1×10⁻⁸ atm·cc/sec He), and thermal shock specifications required for aerospace deployment. The package is lead-finished with 90Pb/10Sn for compatibility with legacy tin-lead solder reflow profiles.
How does the dual chip select (CS1/CS2) architecture of 5962-3829410MZA improve system-level power management?
The 5962-3829410MZA implements hierarchical chip select logic where CS2 has priority over CS1: if CS2 is LOW, the device enters standby regardless of CS1 state. This allows system designers to gate power to entire memory banks using CS2 while retaining fine-grained addressing control via CS1-enabling dynamic power partitioning in multi-processor avionics architectures without software intervention or clock gating.
