Product details
Overview
5962-3829412MZA 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 5V single-supply operation. It supports battery backup data retention down to 2V (L version), operates across –55°C to +125°C, and complies with MIL-STD-883 Class B for high-reliability defense and aerospace systems.
For engineers reviewing the 5962-3829412MZA datasheet, 5962-3829412MZA pinout, 5962-3829412MZA application, or 5962-3829412MZA equivalent, key selection criteria include military temperature compliance, 20ns read cycle timing, low-power standby mode activation via CS1/CS2 control, and CERDIP package compatibility with legacy board layouts.
Technical Context
The 5962-3829412MZA implements fully static asynchronous architecture-no clocks or refresh required-and uses dual chip select (CS1/CS2) logic where CS2 powers down CS1 but not vice versa. Standby current drops to 2µA (typ.) at military temperature when deselected.
It features TTL-compatible input thresholds (VIH = 2.2V min, VIL = 0.8V max), output drive capability of ±10mA, and data retention at VCC ≥ 2.0V with ICCDR ≤ 300µA (military grade). All AC timing parameters-including tAA = 20ns, tRC = 20ns, and tOE = 8ns-are guaranteed over –55°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 8K × 8-bit (65,536 bits), enabling byte-wide data bus interfacing without external demultiplexing |
| Access Time (tAA) | 20ns max at –55°C to +125°C - meets tight timing budgets in real-time avionics and radar processing |
| Supply Voltage | 5.0V ±10% - compatible with legacy 5V TTL/CMOS system rails without level-shifting |
| Standby Current (ISB) | 2µA typical at VCC = 5V, TA = +25°C - enables ultra-low-power hold mode during processor sleep cycles |
| Data Retention Voltage | 2.0V minimum (L version only) - sustains memory contents during brown-out or battery-backup operation |
| Operating Temperature | –55°C to +125°C - qualified per MIL-STD-883 Class B for deployment in harsh environmental enclosures |
| Package | 28-pin 600-mil CERDIP (CD28) - hermetically sealed ceramic package with proven long-term reliability in space and defense platforms |
Pinout & Package
5962-3829412MZA is supplied in a 28-pin 600-mil CERDIP (CD28) package with 0.6-inch width, ceramic body, and gold-plated leads. Pin 1 is marked by a dot; pin numbering follows standard DIP convention (counterclockwise from top-left).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A12 | Address Inputs | 13-bit address bus accepting TTL-level signals; fully static-no setup/hold timing required |
| I/O0–I/O7 | Bidirectional Data Bus | Three-state TTL-compatible I/O lines; high-impedance when CS1 HIGH or CS2 LOW |
| CS1, CS2 | Chip Select Inputs | Active-LOW CS1 and active-HIGH CS2 enable hierarchical power-down: CS2 forces standby even if CS1 is asserted |
| WE | Write Enable | Active-LOW control for write cycles; latches data on falling edge when CS1/CS2 are active |
| OE | Output Enable | Active-LOW control for output drivers; independent of WE, allowing read-modify-write sequences |
| VCC, GND | Power Supply | Single 5V supply with decoupling recommended at package pins; no separate ground plane required |
Key Features
| Feature | Design Value |
|---|---|
| High-speed 20ns access | Guaranteed tAA ≤ 20ns across full military temperature range - eliminates wait states in FPGA- or microcontroller-based memory interfaces |
| Dual chip select power management | CS2-driven automatic standby reduces ISB to 2µA typ., enabling deterministic low-power modes without software intervention |
| Battery backup data retention | Operates down to VCC = 2.0V with ICCDR ≤ 300µA - supports uninterrupted memory state during primary power loss in mission-critical systems |
| MIL-STD-883 Class B compliance | Qualified for screening including burn-in, thermal cycling, and mechanical shock - satisfies DO-254 and MIL-HDBK-217F reliability requirements |
| TTL-compatible interface | VIH ≥ 2.2V, VIL ≤ 0.8V, VOH ≥ 2.4V, VOL ≤ 0.4V - interoperable with legacy 5V logic families without level translators |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8763301XA | Same 8K×8 organization and 20ns speed, but fabricated by Texas Instruments; uses 28-pin 300-mil CERDIP (SD28) | Lacks 2V data retention; rated only for –55°C to +125°C with higher ISB (5µA typ.) | Select when footprint compatibility with SD28 is required and battery backup is unnecessary |
| 5962-9213701MXA | Renesas IDT7164S derivative; identical pinout and timing, but qualified to MIL-PRF-38535 Class K instead of Class B | Class K screening includes additional lot acceptance tests but same functional specs and temperature range | Prefer for programs requiring Class K conformance documentation without redesigning layout or firmware |
Compared with 5962-3829412MZA, 5962-8763301XA offers identical speed and military temp rating but omits low-voltage retention, while 5962-9213701MXA delivers identical electrical behavior with enhanced process traceability under Class K-making it suitable for new designs requiring stricter process controls.

FAQ
What is the guaranteed maximum access time for 5962-3829412MZA across its full military temperature range?
The 5962-3829412MZA guarantees a maximum address access time (tAA) of 20ns over the full –55°C to +125°C operating temperature range, as verified per MIL-STD-883 test method 3012. This value is production-tested and applies to all devices shipped under this part number, ensuring timing predictability in real-time defense systems without derating.
Does 5962-3829412MZA support battery backup operation, and what is the minimum retention voltage?
Yes, the 5962-3829412MZA (L version) supports battery backup operation with guaranteed data retention at VCC ≥ 2.0V, as specified in Table 10 of the Renesas datasheet. This feature allows memory contents to persist during main power interruption, making it suitable for secure key storage and fault-recording applications in tactical radios and flight control units.
Which package type is used for 5962-3829412MZA, and is it hermetically sealed?
The 5962-3829412MZA is packaged in a 28-pin 600-mil CERDIP (CD28) - a ceramic dual in-line package with glass-sealed lid and gold-plated leads. It is fully hermetically sealed per MIL-STD-883 requirement 1014, providing moisture resistance and long-term reliability in high-humidity or vacuum environments such as satellite payloads.
How does the dual chip select (CS1/CS2) architecture of 5962-3829412MZA reduce system power consumption?
The 5962-3829412MZA uses asymmetric chip select logic: CS2 (active-HIGH) forces standby mode regardless of CS1 state, while CS1 (active-LOW) alone enables normal operation. This allows hierarchical power gating - for example, asserting CS2 during processor idle periods cuts ISB to 2µA (typ.), eliminating dynamic switching losses without firmware overhead.
Is 5962-3829412MZA compliant with MIL-STD-883, and which qualification class applies?
Yes, the 5962-3829412MZA is fully compliant with MIL-STD-883 and qualified to Class B per test requirements in Method 1014 (hermeticity), 2003 (thermal cycling), and 2015 (burn-in). Class B certification confirms suitability for high-reliability military applications including airborne, ground mobile, and space-qualified systems.
