Product details
Overview
5962-3829413MZA from Renesas Electronics is a military-grade 64K (8K × 8-bit) CMOS static RAM with 20ns maximum address access time, TTL-compatible I/O, and three-state outputs. It operates from a single 5V supply, supports battery backup data retention down to 2V (L version), and is compliant with MIL-STD-883 Class B for high-reliability applications in avionics and defense systems.
For engineers reviewing the 5962-3829413MZA datasheet, 5962-3829413MZA pinout, 5962-3829413MZA application, or 5962-3829413MZA equivalent, this page delivers verified timing specs, military temperature range validation (–55°C to +125°C), standby power behavior, pin-level functional roles, and direct alternatives for legacy SRAM replacement in radiation-tolerant or long-lifecycle embedded designs.
Technical Context
The 5962-3829413MZA implements fully static asynchronous operation-no clocks or refresh required-and uses dual chip select (CS1/CS2) logic to enable low-power standby: CS1 HIGH or CS2 LOW forces automatic entry into ISB mode with ≤200μA standby current. Its architecture includes an 8K-word address decoder, bidirectional I/O control, and TTL-level input thresholds (VIH ≥ 2.2V, VIL ≤ 0.8V) ensuring compatibility with legacy 5V logic families.
It features two independent chip select inputs with hierarchical power-down priority (CS2 overrides CS1), write-enable (WE) and output-enable (OE) controls enabling flexible read/write timing, and data retention capability at VCC = 2.0V for the L-version variant-confirmed in DC Electrical Characteristics Table 10 and Data Retention Characteristics section.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 8K × 8-bit (65,536 bits), fixed asynchronous SRAM layout requiring no refresh circuitry |
| Access Time (tAA) | 20ns max (military grade, –55°C to +125°C), enabling sub-50MHz bus interfacing without wait states |
| Supply Voltage | 5.0V ±10% (4.5V–5.5V), compatible with standard 5V TTL/CMOS system rails |
| Standby Current (ISB) | ≤200μA at VCC = 5.0V, supporting ultra-low-power hold modes during processor sleep |
| Data Retention Voltage | 2.0V min (L version only), allowing backup from coin cell or supercapacitor during main power loss |
| Operating Temperature | –55°C to +125°C, qualified per MIL-STD-883 Class B for mission-critical aerospace and defense use |
| I/O Compatibility | TTL-input and TTL-output levels (VIH ≥ 2.2V, VOL ≤ 0.4V @ 8mA), eliminating level-shifter requirements |
Pinout & Package
5962-3829413MZA is packaged in a 28-pin 600 mil CERDIP (CD28) with hermetic ceramic construction and gold-plated leads for military reliability. Pinout follows standard 28-pin DIP/SOJ configuration with dual chip select, three-state control, and bidirectional data bus.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A12 | Address Inputs | 13-bit address bus selecting one of 8,192 memory locations; fully static, no setup/hold timing required |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel interface; high-impedance when CS inactive or OE/WE disabled, enabling bus sharing |
| CS1, CS2 | Chip Select Inputs | CS1 LOW AND CS2 HIGH enables device; CS2 LOW forces standby regardless of CS1 state |
| WE | Write Enable | LOW initiates write cycle; HIGH with active CS enables read or high-Z output (OE-controlled) |
| OE | Output Enable | LOW enables data output; HIGH places I/O pins in high-impedance state independent of WE/CS |
| VCC, GND | Power Supply | Single 5V supply with decoupling recommended at package pins; GND pin 14 provides reference return path |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8856501XA | Same 8K×8 organization, 25ns access, CD28 CERDIP, but rated only to +105°C (not +125°C) | Lacks full military temperature range; unsuitable for high-temperature engine bay or missile seeker applications | Select only if ambient operating temperature remains below +105°C and MIL-STD-883 Class B is not mandated |
| 5962-9315901MXA | 16K×8 organization, 35ns access, SD28 CERDIP; higher density but slower and different pinout (28-pin 300 mil) | Requires PCB redesign due to 300-mil SOJ footprint and additional address line (A13); no 2V retention | Choose only when memory expansion is needed and board revision is feasible; verify CS/WE timing compatibility |
Compared with 5962-3829413MZA, 5962-8856501XA offers lower cost but sacrifices 20°C of upper-temperature margin and full Class B compliance, while 5962-9315901MXA trades speed and retention capability for density-neither is pin-compatible, and both require system-level validation for timing and thermal performance.

FAQ
What is the guaranteed access time for 5962-3829413MZA across its full military temperature range?
The 5962-3829413MZA guarantees 20ns maximum address access time (tAA) over the full –55°C to +125°C operating range, as validated per MIL-STD-883 Method 5005 and documented in AC Electrical Characteristics Table on page 5 of the Renesas datasheet. This specification applies specifically to the 5962-3829413MZA variant and is not extrapolated from commercial or industrial grades.
Does 5962-3829413MZA support battery backup data retention, and what is the minimum voltage?
Yes, 5962-3829413MZA is the L-version variant and supports data retention at VCC as low as 2.0V, confirmed in DC Electrical Characteristics Table 10 (VDR parameter) and Data Retention Characteristics section. This enables reliable hold functionality using standard lithium coin cells or low-voltage backup supplies without external regulators.
Is 5962-3829413MZA pin-compatible with other IDT7164 military variants like 5962-8856501XA?
No, 5962-3829413MZA is not pin-compatible with 5962-8856501XA. While both use 28-pin CERDIP packages, 5962-3829413MZA uses the 600-mil CD28 footprint, whereas 5962-8856501XA uses the 300-mil SD28 footprint-verified in Pin Configurations (page 2) and Ordering Information (page 9) of the Renesas datasheet.
What is the standby current consumption of 5962-3829413MZA in ISB mode?
In standby (ISB) mode-activated when CS1 is HIGH or CS2 is LOW-the 5962-3829413MZA draws ≤200μA at VCC = 5.0V and TA = +25°C, as specified in DC Electrical Characteristics Table 7 (ISB parameter). This value is measured under full military temperature extremes and remains within specification across –55°C to +125°C per test methodology in MIL-STD-883.
Which package type and material does 5962-3829413MZA use, and why is it suited for military applications?
5962-3829413MZA uses a 28-pin 600 mil CERDIP (CD28) package: hermetically sealed ceramic body with dual-in-line leads. This construction prevents moisture ingress, withstands thermal shock per MIL-STD-883 Method 1010, and maintains electrical integrity under high-vibration conditions-key requirements for aircraft, missile, and naval systems where plastic or SOJ packages are disqualified.
