Product details
Overview
5962-3829411MZA from Renesas Electronics is a military-grade 64K (8K × 8-bit) CMOS static RAM with 20ns max 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-down via dual chip select logic (CS1/CS2), making it suitable for avionics, radar processors, and hardened embedded systems requiring nonvolatile SRAM persistence under brownout conditions.
For engineers reviewing the 5962-3829411MZA datasheet, 5962-3829411MZA pinout, 5962-3829411MZA application, or 5962-3829411MZA equivalent, this page delivers verified military-spec timing parameters, MIL-STD-883 Class B compliance details, CERDIP package mapping, DC/AC electrical limits across –55°C to +125°C, and validated drop-in alternatives for legacy system sustainment and radiation-tolerant design reuse.
Technical Context
The 5962-3829411MZA implements fully static asynchronous operation-no clocks or refresh required-and uses dual chip select (CS1 active-low, CS2 active-high) to enable precise low-power standby control. Its architecture includes address decoding for 13-bit A0–A12 inputs, bidirectional 8-bit I/O0–I/O7 bus, and write-enable (WE)/output-enable (OE) controls that govern data flow direction and output state.
It features two distinct power modes: active operation with typical ICC of 110mA at 20ns speed, and standby mode (ISB) drawing ≤5µA when CS1 is high or CS2 is low. The L-version adds guaranteed 2V data retention with ICCDR ≤200µA at military temperature extremes, validated per MIL-STD-883 test method 1017.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64K (8,192 × 8-bit) - supports byte-wide data paths without external multiplexing |
| Access Time (tAA) | 20ns max (military grade, –55°C to +125°C) - enables direct interface with 50MHz bus cycles |
| Supply Voltage | 5.0V ±10% - compatible with standard TTL/CMOS logic rails; no auxiliary voltage required |
| Data Retention Voltage | 2.0V min (L-version only) - preserves memory contents during main supply collapse in mission-critical holdover |

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, 25ns access, 28-pin CERDIP, but no 2V data retention; rated –55°C to +125°C | Lacks battery backup capability; unsuitable for brownout-hold applications | Select when cost-sensitive designs tolerate 5V-only operation and require proven field history |
| 5962-9213901MXA | 20ns access, 28-pin CERDIP, supports 2V retention, but uses single CS input (not dual CS1/CS2) | Simpler control logic but loses independent standby gating; requires redesign of chip select routing | Choose for new designs prioritizing retention and speed where board layout allows CS simplification |
Compared with 5962-3829411MZA, 5962-8856901XA trades retention capability for lower acquisition cost and broader legacy support, while 5962-9213901MXA retains the 2V feature but sacrifices the dual-CS power-gating flexibility essential for multi-bank memory arbitration in complex avionics systems.

FAQ
What is the maximum operating temperature range certified for the 5962-3829411MZA?
The 5962-3829411MZA is certified for continuous operation from –55°C to +125°C, fully compliant with MIL-STD-883 Class B environmental testing requirements including temperature cycling, thermal shock, and high-temperature life testing. This range is validated across all electrical parameters in the datasheet, including 20ns access time and 2V data retention performance.
Does the 5962-3829411MZA require an external clock or refresh circuitry?
No, the 5962-3829411MZA is a fully static RAM and requires no external clock or refresh signals. Its internal CMOS latches retain data indefinitely as long as VCC remains within specification and the device is not written to. This eliminates timing-critical refresh overhead in real-time embedded systems.
What package type is used for the 5962-3829411MZA, and is it lead-free?
The 5962-3829411MZA is packaged in a 28-pin 600-mil CERDIP (ceramic dual in-line package), designated CD28. Per Renesas documentation, this variant is not RoHS-compliant and contains leaded solder; "Green" versions (Pb-free) are not offered for this military-spec part number.
How does the dual chip select (CS1/CS2) architecture of the 5962-3829411MZA improve system power management?
The 5962-3829411MZA's CS1 (active-low) and CS2 (active-high) inputs allow hierarchical power gating: asserting CS2 LOW or CS1 HIGH forces the device into ultra-low-power standby (ISB ≤5µA), independent of bus activity. This enables selective memory bank shutdown in multi-SRAM systems without disrupting adjacent devices on shared data/address lines.
Is the 5962-3829411MZA pin-compatible with commercial-grade IDT7164L20YG variants?
No-while functionally identical, the 5962-3829411MZA uses a 600-mil CERDIP (CD28) package, whereas IDT7164L20YG uses a 300-mil SOJ (PJG28) package. Pin functions match exactly (A0–A12, I/O0–I/O7, CS1, CS2, WE, OE, VCC, GND), but physical dimensions, lead pitch, and mounting requirements differ significantly; PCB redesign is required for substitution.
