Product details
Overview
5962-3829410MXA from Renesas Electronics is a military-grade 64K (8K × 8-bit) CMOS static RAM with 20 ns maximum address access time, TTL-compatible I/O, three-state outputs, and battery backup data retention down to 2 V (L-version). It operates from a single 5 V supply and supports standby power-down via dual chip select (CS1/CS2) control. It is used in avionics, radar processors, and hardened embedded systems requiring non-volatile SRAM hold during brownout.
For engineers reviewing the 5962-3829410MXA datasheet, 5962-3829410MXA pinout, 5962-3829410MXA application, or 5962-3829410MXA 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 direct alternative part comparisons for legacy system sustainment.
Technical Context
The 5962-3829410MXA 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 ≤200 µA (military grade).
It features TTL-compatible input thresholds (VIH ≥ 2.2 V, VIL ≤ 0.8 V), output drive capability of IOH = –4 mA / IOL = 8 mA at VCC = 4.5 V, and data retention at VCC ≥ 2.0 V with ICCDR ≤ 300 µA over full temperature range. All AC timing-including tAA, tRC, tOE, tWHZ-is specified for military temperature (–55°C to +125°C) and validated per MIL-STD-883.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 8K × 8-bit (65,536 bits), byte-wide parallel interface |
| Access Time (tAA) | 20 ns max - enables sub-50 MHz bus interfacing in real-time control loops |
| Supply Voltage | 5.0 V ±10% - compatible with standard TTL/CMOS logic rails without regulation overhead |
| Operating Temperature | –55°C to +125°C - qualified per MIL-STD-883 Class B for flight-critical hardware |
| Data Retention Voltage | 2.0 V min (L-version only) - sustains memory state during 3 V battery backup or brownout |
| Standby Current (ISB) | ≤200 µA at VCC = 5.0 V - enables ultra-low-power hold mode in dormant subsystems |
| Input/Output Compatibility | TTL-level - eliminates level-shifter requirements in mixed-logic designs |
Pinout & Package
5962-3829410MXA is supplied in a 28-pin 600 mil hermetically sealed CERDIP (CD28) package compliant with MIL-STD-883 Class B screening. Pin 1 is marked with a dot; pinout follows JEDEC MS-012 standard orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A12 | Address Inputs | 13-bit address bus for 8K-word selection; latched on CS1/CS2 enable edge |
| I/O0–I/O7 | Bidirectional Data Bus | Three-state CMOS I/O pins; high-impedance when CS inactive or OE HIGH |
| CS1, CS2 | Chip Select Inputs | Active-LOW CS1 and active-HIGH CS2 require simultaneous assertion for read/write; CS2 dominates power-down |
| WE | Write Enable | Active-LOW control for write cycles; overlaps with CS1/CS2 to define write window |
| OE | Output Enable | Active-LOW control for output drivers; independent of WE for read-before-write sequences |
| VCC, GND | Power Supply | Single 5 V rail; decoupling required within 0.5 inch due to fast edge rates (tR/tF ≤ 5 ns) |
Key Features
| Feature | Design Value |
|---|---|
| High-speed military access | 20 ns tAA guaranteed over –55°C to +125°C - meets radar pulse timing budgets |

| Battery backup retention | 2.0 V VCC retention threshold (L-version) - supports 3 V lithium backup without regulator |
| MIL-STD-883 Class B compliance | Full screening including burn-in, thermal cycling, and radiation hardness assurance - certified for space-qualified platforms |
| Hermetic CERDIP packaging | 600 mil CD28 ceramic DIP - prevents moisture ingress and ensures long-term reliability in humid/harsh environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8856301XA | Same 8K×8 organization, 25 ns tAA, CD28 CERDIP, but no L-version data retention; higher ISB (500 µA) | Lacks 2 V battery backup - unsuitable for brownout-critical crypto or avionics hold modes | Select when cost sensitivity outweighs retention requirement and 25 ns timing suffices |
| 5962-9213901MXA | 20 ns tAA, SD28 300 mil CERDIP, same L-version retention, but lower ICCDR (150 µA) and tighter tOH tolerance (8 ns vs 10 ns) | Smaller footprint - advantageous in space-constrained missile guidance PCBs | Prefer for new designs where board area is constrained and SD28 soldering process is established |
Compared with 5962-3829410MXA, 5962-8856301XA trades retention capability for lower acquisition cost, while 5962-9213901MXA offers identical timing and retention in a smaller CERDIP variant-enabling layout optimization without sacrificing MIL-STD-883 reliability.

FAQ
What is the maximum operating temperature range for the 5962-3829410MXA?
The 5962-3829410MXA is rated for continuous operation from –55°C to +125°C and is fully screened per MIL-STD-883 Class B, including thermal cycling and high-temperature life testing. This range is validated for all DC and AC parameters in the official Renesas datasheet revision Jul.30.20, making it suitable for engine-mounted or space-exposed applications where ambient extremes exceed commercial or industrial grades.
Does the 5962-3829410MXA support battery backup data retention?
Yes, the 5962-3829410MXA is the L-version variant and supports data retention at VCC as low as 2.0 V, with ICCDR ≤ 300 µA across the full military temperature range. This capability is explicitly documented in Table 10 (Data Retention Characteristics) of the Renesas datasheet and enables use with 3 V lithium backup cells without voltage regulation.
What package type is used for the 5962-3829410MXA?
The 5962-3829410MXA is packaged in a 28-pin 600 mil hermetically sealed CERDIP (CD28) package, as confirmed in the Ordering Information table (page 10) and Pin Configuration diagram (page 5) of the Renesas datasheet. This package meets MIL-STD-1835 and provides superior moisture resistance and thermal stability versus plastic DIP or SOJ variants.
Is the 5962-3829410MXA pin-compatible with commercial versions of the IDT7164?
No-while functionally identical, the 5962-3829410MXA uses the CD28 (600 mil CERDIP) footprint, whereas commercial IDT7164S/L parts commonly use PTG28 (plastic DIP) or PJG28 (SOJ). Pin numbering and signal assignment match the JEDEC MS-012 standard, but mechanical compatibility requires matching the CD28 land pattern and solder profile.
What are the key timing differences between read cycle #1 and read cycle #2 for the 5962-3829410MXA?
Read Cycle #1 (Figure 5) assumes continuous selection (CS1 LOW, CS2 HIGH) and defines tAA relative to CS1, while Read Cycle #2 (Figure 6) uses CS2 transition to initiate access and specifies tACS2. The latter allows faster turnaround when toggling CS2 alone-critical in multiplexed memory banks. Both cycles guarantee tAA ≤ 20 ns under military conditions, as tabulated in AC Electrical Characteristics (pages 5–6).
