Product details
Overview
5962-3829417MZA 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 battery backup data retention down to 2V (L-version). It operates from a single 5V supply and supports standby power-down via dual chip select (CS1/CS2) control-used in avionics, radar processors, and hardened embedded systems requiring non-volatile SRAM persistence under brownout.
For engineers reviewing the 5962-3829417MZA datasheet, 5962-3829417MZA pinout, 5962-3829417MZA application, or 5962-3829417MZA equivalent, key selection criteria include MIL-STD-883 Class B compliance, -55°C to +125°C operation, 28-pin CERDIP package, 2V data retention capability, and CS-controlled low-power standby behavior.
Technical Context
The 5962-3829417MZA 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 memory array is organized as 8,192 words × 8 bits, with address decoding supporting A0–A12 inputs and bidirectional I/O0–I/O7 lines.
Standby current drops to ≤200 µA (military grade) when CS1 is HIGH or CS2 is LOW; the L-version adds data retention at VCC ≥ 2.0V with ICCDR ≤ 300 µA across full temperature range. Input/output timing adheres to TTL voltage thresholds (VIH = 2.2V min, VIL = 0.8V max) and guarantees tAA ≤ 20ns, tOH ≤ 10ns, and tPD ≤ 20ns under MIL conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8857501XA | Same 8K×8 organization, 25ns access, 28-pin CERDIP, but no 2V retention - requires external backup circuitry | Lacks battery backup mode; suitable only where continuous power is guaranteed | Select when cost sensitivity outweighs brownout resilience requirements |
| AS6C4008-20TIN | Commercial-grade 512K×8 SRAM, 20ns, 32-pin TSOP - higher density but non-hermetic, non-MIL screened | Not qualified for aerospace use; lacks MIL-STD-883 testing and extended temperature validation | Use only in ground-based industrial systems with controlled environments and no certification mandates |
Compared with 5962-3829417MZA, 5962-8857501XA trades data retention for lower unit cost and broader speed availability, while AS6C4008-20TIN offers higher density at the expense of reliability assurance-making 5962-3829417MZA the sole choice for certified safety-critical hardware requiring guaranteed data persistence and environmental hardening.

FAQ
What is the operating temperature range for the 5962-3829417MZA?
The 5962-3829417MZA is rated for -55°C to +125°C operation and fully qualified per MIL-STD-883 Class B. This includes screening for thermal cycling, mechanical shock, and steady-state bias life testing-ensuring reliable function in jet engine bays, satellite payloads, and artillery fire control systems where ambient extremes exceed commercial or industrial specifications. The 5962-3829417MZA maintains full timing compliance across this entire range.
Does the 5962-3829417MZA support battery backup operation?
Yes-the 5962-3829417MZA is the "L" version of the IDT7164 family and supports data retention at VCC ≥ 2.0V. During brownout or main supply loss, the device enters low-power retention mode with ICCDR ≤ 300 µA across -55°C to +125°C. This eliminates need for external backup batteries or supercapacitors in space- or weight-constrained platforms such as UAV flight controllers and handheld radios.
What package type is used for the 5962-3829417MZA?
The 5962-3829417MZA is packaged in a 28-pin 600-mil CERDIP (CD28) - a hermetically sealed ceramic dual in-line package with gold-plated leads and glass-metal seal. This construction provides superior moisture resistance, thermal stability, and radiation tolerance compared to plastic DIP or SOJ variants, meeting MIL-PRF-38535 requirements for high-reliability military electronics.
How does chip select logic work on the 5962-3829417MZA?
The 5962-3829417MZA uses dual chip select inputs: CS1 (active-LOW) and CS2 (active-HIGH). Both must be asserted simultaneously for normal read/write operation. Critically, CS2 has priority: if CS2 goes LOW while CS1 remains LOW, the device immediately enters standby mode-even if CS1 stays active. This asymmetric logic enables fail-safe power-down in fault scenarios, a key requirement in DO-178C-certified avionics software stacks.
Is the 5962-3829417MZA pin-compatible with other IDT7164 variants?
Yes-the 5962-3829417MZA shares identical pinout, electrical interface, and functional behavior with all IDT7164S/L military-grade variants in 28-pin CERDIP (CD28), including 5962-8857501XA and 5962-9202801MXA. Differences are limited to access time (20ns vs. 25ns/35ns) and retention capability (L vs. S), allowing drop-in replacement where timing margins permit. No PCB layout changes are required for substitution within the same package code.
