Product details
Overview
5962-8552512XA from Renesas Electronics is a military-grade 64K (8K × 8-bit) CMOS static RAM with 20ns max 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 supply and supports battery backup data retention down to 2V (L-version). It is used in avionics, radar processors, and hardened embedded systems requiring deterministic timing and radiation-tolerant memory.
For engineers reviewing the 5962-8552512XA datasheet, 5962-8552512XA pinout, 5962-8552512XA application, or 5962-8552512XA equivalent, this page delivers verified military-spec SRAM parameters including MIL-STD-883 Class B compliance, -55°C to +125°C operation, 28-pin CERDIP package mapping, and direct replacement guidance for legacy IDT7164L-based designs.
Technical Context
The 5962-8552512XA 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 standby current drops to ≤200μA (MIL) under full deselect conditions (CS1 > VH, CS2 < VL), enabling ultra-low quiescent power in mission-critical hold modes.
It features TTL-compatible input thresholds (VIL = 0.8V max, VIH = 2.2V min), output drive capability of ±10mA, and guaranteed AC timing across military temperature range-including tAA = 20ns, tRC = 20ns, and tOE = 8ns-validated per MIL-STD-883 test methods.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| 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 missile guidance loops |
| Supply Voltage | 5.0V ±10% - compatible with legacy 5V TTL/CMOS system rails without level-shifting |
| Data Retention Voltage | 2.0V min (L-version only) - sustains memory state during brownout or battery fallback |
| Standby Current (ISB) | ≤200μA at +125°C - reduces thermal load in sealed, conduction-cooled enclosures |
| Operating Temperature | -55°C to +125°C - qualified per MIL-STD-883 Class B for airborne and space-qualified platforms |
| Package | 28-pin 600-mil CERDIP (CD28) - hermetically sealed, leaded ceramic for high-reliability environments |
Pinout & Package
5962-8552512XA is supplied in a 28-pin 600-mil CERDIP (CD28) package with 0.6-inch width, ceramic body, and through-hole leads. Pin 1 is marked by a dot; pin numbering follows standard DIP convention (counterclockwise from top-left corner).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A12 | Address Inputs | 13-bit address bus supporting full 8K-word decoding; no internal latching - requires stable address before CS activation |
| I/O0–I/O7 | Bidirectional Data Bus | Three-state TTL-compatible I/O lines; high-impedance when CS inactive or OE HIGH during read |
| CS1 / CS2 | Chip Select Inputs | CS1 active LOW, CS2 active HIGH; CS2 forces standby regardless of CS1 state - enables hierarchical memory enable control |
| WE | Write Enable | Active LOW write strobe; write occurs only when WE, CS1 LOW, and CS2 HIGH overlap - prevents spurious writes during power transients |
| OE | Output Enable | Active LOW enables output drivers; outputs remain high-Z if OE HIGH during read - supports bus sharing with other peripherals |
| VCC / GND | Power Supply | Single 5V supply with dedicated ground pin; decoupling required within 0.5 inch of VCC/GND pair for EMI suppression |
Key Features
| Feature | Design Value |
|---|---|
| Fully static operation | No clocks or refresh cycles needed - eliminates timing jitter and simplifies FPGA/CPU interface logic |
| Dual chip select with priority logic | CS2 overrides CS1 for standby entry - enables fail-safe power-down in multi-SRAM systems |
| Battery backup data retention | Maintains valid data at VCC ≥ 2.0V - supports seamless transition to backup power in flight control computers |
| TTL-compatible I/O levels | Direct interface with 5V microcontrollers and FPGAs without level translators - reduces BOM count and layout complexity |
| MIL-STD-883 Class B qualification | Includes screening for mechanical shock, thermal cycling, and burn-in - meets DO-254/DO-160 for airborne applications |
Applications
| Avionics Flight Control Memory | Radar Signal Processing Buffer |

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 uses 28-pin 300-mil CERDIP (SD28); lower ISB (150μA max) | Preferred for space-constrained PCBs where 600-mil width is prohibitive; identical MIL-STD-883 Class B screening | Select when board real estate is limited and thermal envelope allows tighter pitch; verify socket compatibility. |
| 5962-9213901XA | 25ns access time, same CD28 package, but rated for -55°C to +105°C (not +125°C); higher ISB (300μA) | Suitable for ground vehicle and naval platforms where extended high-temp operation is unnecessary | Choose for cost-sensitive defense programs with relaxed thermal specs; avoids premium pricing of +125°C grade. |
Compared with 5962-8552512XA, 5962-8763301XA offers identical performance in a smaller footprint but requires revised socket layout, while 5962-9213901XA trades 20°C thermal margin for lower procurement cost and broader commercial availability.

FAQ
What is the maximum operating temperature range certified for the 5962-8552512XA?
The 5962-8552512XA is certified for continuous operation from -55°C to +125°C per MIL-STD-883 Class B requirements. This rating is validated across all electrical parameters including tAA, ISB, and VOL, and applies specifically to the CD28 CERDIP package variant. The device undergoes thermal cycling, burn-in, and parameter testing at both extremes to ensure reliability in jet engine bays and satellite payload compartments.
Does the 5962-8552512XA support battery backup operation, and what is the minimum retention voltage?
Yes, the 5962-8552512XA (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 is exclusive to the "L" suffix variants and is validated across the full military temperature range. At +125°C, retention current remains ≤200μA, enabling multi-year hold time on small lithium-thionyl chloride cells.
Is the 5962-8552512XA pin-compatible with commercial IDT7164S/L devices?
No - while functionally identical to the IDT7164L20DB, the 5962-8552512XA is a screened military derivative with enhanced reliability testing and tighter parameter limits. Its pinout matches the 28-pin CD28 CERDIP footprint, but commercial IDT7164L20DB units lack MIL-STD-883 Class B qualification and do not guarantee operation above +85°C. Direct substitution requires requalification per DO-254.
What are the absolute maximum ratings for VTERM and storage temperature of the 5962-8552512XA?
The absolute maximum terminal voltage (VTERM) for the 5962-8552512XA is -0.5V to +7.0V relative to GND, and the maximum storage temperature is -65°C to +150°C. These ratings are defined in Table 2 of the Renesas datasheet and apply to the CD28 package. Exceeding either limit risks permanent damage, even if applied briefly during handling or rework.
How does the dual chip select architecture (CS1/CS2) function in the 5962-8552512XA?
In the 5962-8552512XA, CS1 is active LOW and CS2 is active HIGH. When CS2 goes LOW, the device enters standby regardless of CS1 state - this priority logic ensures fail-safe power-down. Standby current drops to ≤200μA, and outputs go high-Z. Full deselect requires either CS1 HIGH or CS2 LOW; partial deselect (CS1 HIGH, CS2 HIGH) leaves outputs in high-Z but retains internal state.
