Product details
Overview
5962-3829406MZA 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 retains data down to 2V in L-version variants, making it suitable for ruggedized avionics and defense computing systems requiring high reliability under extreme temperature cycling.
For engineers reviewing the 5962-3829406MZA datasheet, 5962-3829406MZA pinout, 5962-3829406MZA application, or 5962-3829406MZA equivalent, this page delivers verified timing parameters, MIL-STD-883 Class B compliance details, DC/AC electrical specs across –55°C to +125°C, package-specific pin mapping, and validated alternative parts for legacy system sustainment and obsolescence mitigation.
Technical Context
The 5962-3829406MZA 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 standby current drops to ≤200μA (L version) at full military temperature range, enabled by automatic transition when CS1 goes HIGH or CS2 goes LOW.
It supports WE-controlled and CS-controlled write cycles with defined tWP (15ns min), tWHZ (5ns), and tDW (5ns) timing constraints. Input leakage is ≤2μA, output drive meets TTL VOH ≥2.4V / VOL ≤0.4V at IOL = 8mA, and I/O capacitance is 8pF-critical for signal integrity in high-density military backplanes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 8K × 8-bit (65,536 bits), byte-wide parallel interface for direct CPU bus coupling |
| Access Time (tAA) | 20ns max at VCC = 5.0V ±10%, TA = –55°C to +125°C - enables real-time deterministic read latency in flight control systems |
| Supply Voltage | 5.0V ±10% (4.5–5.5V); data retention supported down to 2.0V (L version only) - allows seamless battery backup during main power interruption |
| Operating Temperature | –55°C to +125°C per MIL-STD-883 Class B - qualified for missile guidance, radar processing, and space-qualified subsystems |
| Standby Current (ISB) | ≤200μA (L version), ≤2mA (S version) - reduces thermal load and extends battery life in unattended field-deployed equipment |
| I/O Interface | TTL-compatible inputs/outputs, three-state bidirectional data bus (I/O0–I/O7) - interoperable with legacy 5V microcontrollers and FPGAs without level-shifting |
| Package | 28-pin 600 mil CERDIP (CD28) - hermetically sealed ceramic package for moisture resistance and thermal stability in harsh environments |
Pinout & Package
5962-3829406MZA is supplied in a 28-pin 600 mil CERDIP (CD28) package with 0.600" width, ceramic body, and solder-dip leads. Pin 1 is marked with a dot; pin numbering follows standard DIP convention (counterclockwise from top-left corner).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A12 | Address Inputs | 13-bit address bus accepting full 8K memory space; compatible with Z80, 8086, and MIL-STD-1553B host processors |
| I/O0–I/O7 | Bidirectional Data Bus | Three-state TTL-compatible data lines; high-impedance when CS1 HIGH or CS2 LOW to prevent bus contention |
| CS1, CS2 | Chip Select Inputs | Active-LOW CS1 and active-HIGH CS2 enable hierarchical memory decoding; CS2 override disables CS1 for power gating |
| WE | Write Enable | Active-LOW control for write cycle initiation; timing-critical for meeting tWP (15ns) and tDH (5ns) in synchronous bus protocols |
| OE | Output Enable | Active-LOW control for output drivers; decouples read data from bus when disabled, enabling multi-drop memory architectures |
| VCC, GND | Power Supply | Single 5V supply with dedicated ground plane; bypass capacitor placement adjacent to pins minimizes noise-induced bit errors |

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 CDIP, but rated only to +85°C industrial grade; no 2V retention | Suitable for ground-based test equipment or non-flight-certified subsystems where extended temperature range is unnecessary | Select when cost sensitivity outweighs military environmental requirements and battery backup is not needed |
| 5962-9213701MXA | 64K×8 SRAM with 35ns access, 28-pin SDIP, MIL-STD-883 Class B qualified, but lacks CS2 power-down and 2V retention | Used in legacy radar processors where slower timing is acceptable and board space permits larger package footprint | Choose for drop-in replacement in existing SDIP layouts where power management features are handled externally |
Compared with 5962-3829406MZA, 5962-8856901XA trades military temperature range and data retention for lower unit cost, while 5962-9213701MXA offers same qualification level but requires redesign for CS logic and higher standby current-making 5962-3829406MZA optimal for new designs demanding both ruggedness and ultra-low-power standby.

FAQ
What is the maximum operating temperature range certified for 5962-3829406MZA?
The 5962-3829406MZA is certified for continuous operation from –55°C to +125°C per MIL-STD-883 Class B test requirements. This includes full characterization of AC timing parameters, DC leakage, and data retention at both extremes. The device undergoes thermal shock testing (Method 5011) and steady-state life screening (Method 5005) to validate performance across this range.
Does 5962-3829406MZA support true battery backup operation?
Yes, the 5962-3829406MZA (L version) supports true battery backup: it retains stored data with VCC as low as 2.0V across its full military temperature range. This capability is verified per data retention characteristics table (tCDR = 0ns, VDR = 2.0V, ICCDR ≤200μA), enabling seamless handover to backup power without data loss or external supervision circuitry.
Is 5962-3829406MZA pin-compatible with commercial IDT7164S/L variants?
No-5962-3829406MZA uses the 600 mil CERDIP (CD28) package, whereas commercial IDT7164S/L parts commonly use 300 mil SOJ (PJG28) or plastic DIP (PTG28). While the pin functions are identical, the physical dimensions, lead pitch, and solder profile differ significantly; PCB layout revision is required for substitution.
What is the minimum write pulse width (tWP) guaranteed for 5962-3829406MZA?
The minimum guaranteed write pulse width (tWP) for 5962-3829406MZA is 15ns under all military temperature conditions (–55°C to +125°C) and VCC = 4.5V to 5.5V. This value is production-tested and appears in the AC Electrical Characteristics table for 20ns speed grade devices, ensuring reliable write setup/hold margins in high-speed bus interfaces.
How does the dual chip select (CS1/CS2) logic reduce power consumption in 5962-3829406MZA?
In 5962-3829406MZA, asserting CS1 HIGH or CS2 LOW forces the device into low-power standby mode with ISB ≤200μA (L version). Crucially, CS2 has priority: if CS2 is LOW, the device remains in standby even if CS1 is LOW-enabling hierarchical power gating in multi-chip memory banks without additional control logic.
