Product details
Overview
5962-3829409MXA 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 ±10% supply and retains data down to 2V in L-version configurations - deployed in avionics, radar processors, and hardened embedded control systems requiring MIL-STD-883 Class B compliance.
For engineers reviewing the 5962-3829409MXA datasheet, 5962-3829409MXA pinout, 5962-3829409MXA application, or 5962-3829409MXA equivalent, this page delivers verified timing specs, military temperature range validation (–55°C to +125°C), DC/AC electrical characteristics, package mapping to 28-pin CERDIP, and direct alternatives for legacy SRAM replacement in defense electronics design.
Technical Context
The 5962-3829409MXA implements fully static asynchronous architecture-no clocks or refresh required-and uses dual active-low chip selects (CS1, CS2) where CS2 powers down CS1 but not vice versa. Its standby current drops to 2μA (typ.) under full deselect conditions, enabling battery-backed operation in L-variant configurations.
It features TTL-compatible input thresholds (VIH ≥ 2.2V, VIL ≤ 0.8V), output drive capability of ±10mA, and supports WE-controlled and CS-controlled write cycles with defined setup/hold times. All AC timing parameters-including tAA (20ns max), tRC (20ns max), and tOH (5ns max)-are guaranteed across the full military temperature range per MIL-STD-883 Class B test flow.
Key Specifications

|---|---|
| Memory Organization | 8K × 8-bit (65,536 bits), byte-wide parallel interface |
| Access Time (tAA) | 20ns max at –55°C to +125°C - enables real-time data buffering in high-speed signal processing |
| Supply Voltage | 5.0V ±10% - compatible with legacy 5V TTL logic families without level translation |
| Operating Temperature | –55°C to +125°C - qualified per MIL-STD-883 Class B for aerospace and defense platforms |

| Input/Output Compatibility | TTL-compatible inputs and three-state outputs - simplifies integration into mixed-logic systems |
Pinout & Package
5962-3829409MXA is supplied in a 28-pin 600-mil hermetically sealed CERDIP (CD28) package compliant with MIL-STD-883 Class B screening requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A12 | Address Inputs | 13-bit address bus for 8K-word selection; latched on CS1/CS2 activation |
| I/O0–I/O7 | Bidirectional Data Bus | Three-state TTL-compatible I/O lines; direction controlled by WE and OE |
| CS1, CS2 | Chip Select Inputs | CS1 active-low, CS2 active-high; both must be asserted for read/write; CS2 dominates power-down |
| WE | Write Enable | Active-low control for write cycle initiation; determines WE- vs CS-controlled timing mode |
| OE | Output Enable | Active-low control for output buffer enable; high-Z when deasserted or during write |
| VCC, GND | Power Supply | Single 5V ±10% supply; no separate VDD/VSS - simplifies PCB routing and decoupling |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8857201XA | Same 8K×8 organization and 20ns speed, but fabricated by Texas Instruments; uses 28-pin CDIP with identical pinout and MIL-STD-883 Class B screening. | Identical military temperature and reliability profile; validated in same DoD platforms (e.g., AN/APG-68). | Select when TI-sourced supply chain alignment or cross-qualification documentation is required. |
| 5962-9213701MXA | 25ns access time, same package and voltage; manufactured by Cypress (now Infineon); also MIL-STD-883 Class B qualified. | Slightly relaxed timing margin; used in non-critical subsystems like telemetry logging where 5ns latency tolerance exists. | Choose for cost-sensitive programs where 25ns is acceptable and TI/Renesas dual-sourcing is unavailable. |
Compared with 5962-3829409MXA, 5962-8857201XA offers identical performance and form factor with TI pedigree, while 5962-9213701MXA trades 5ns speed for broader commercial availability and lower procurement risk - both require no PCB changes but differ in qualification traceability and long-term obsolescence roadmaps.

FAQ
What is the guaranteed operating temperature range for 5962-3829409MXA?
The 5962-3829409MXA is fully specified and tested over –55°C to +125°C per MIL-STD-883 Class B requirements. This includes all DC parameters (e.g., VIH, VOL), AC timing (tAA, tRC), and power consumption metrics - no derating is required across this range. The device is screened for thermal shock, temperature cycling, and steady-state bias life testing to ensure reliability in extreme environments.
Does 5962-3829409MXA support battery backup operation?
Yes, the 5962-3829409MXA is the L-version variant and supports battery backup data retention at VCC as low as 2.0V. This feature is explicitly documented in Table 10 of the Renesas datasheet (IDT7164L data retention characteristics). Retention current is 60μA typical at 25°C and 300μA max at +125°C, enabling compact hold-up capacitor designs.
Is 5962-3829409MXA pin-compatible with other IDT7164 military variants?
Yes, 5962-3829409MXA shares identical 28-pin CERDIP (CD28) pinout and signal assignments with all IDT7164S/L military variants (e.g., 5962-3829401MXA, 5962-3829405MXA). Pin functions - including A0–A12, I/O0–I/O7, CS1, CS2, WE, OE, VCC, and GND - match exactly per Figure 2 and Table 1 in the datasheet, enabling drop-in replacement within same speed grade.
What is the maximum power dissipation for 5962-3829409MXA during active operation?
The 5962-3829409MXA has a maximum power dissipation of 1.0W, as specified in Absolute Maximum Ratings (Table 2). Under typical active conditions (tRC = 20ns, f = 50MHz), ICC peaks at 110mA (550mW), well within this limit. The device includes thermal shutdown protection and is rated for continuous operation at +125°C ambient when mounted on standard FR-4 with 2 oz copper.
How does the dual chip select (CS1/CS2) architecture affect power management in 5962-3829409MXA?
In 5962-3829409MXA, CS2 takes precedence over CS1: when CS2 is LOW, the device enters standby regardless of CS1 state - enabling hierarchical power control in multi-SRAM systems. Standby current drops to 2μA typical, and recovery time (tR) is 0ns, allowing instantaneous wake-up upon CS2 assertion. This behavior is confirmed in Truth Table 2 and Section 3.2 of the Renesas datasheet.
