Product details
Overview
5962-8700202ZA from IDT is a military-grade 2K × 8 dual-port static RAM with master arbitration logic, 25ns/35ns access time (max), TTL-compatible 5V ±10% operation, and on-chip BUSY flag for port contention resolution-used in real-time avionics data buffers and radar signal processing memory interfaces.
For engineers reviewing the 5962-8700202ZA datasheet, 5962-8700202ZA pinout, 5962-8700202ZA application, or 5962-8700202ZA equivalent, this page delivers verified military-spec timing, dual-port arbitration behavior, flatpack package layout, battery-retention capability (LA variant), and direct substitution guidance for QML-38535-compliant system design.
Technical Context
The 5962-8700202ZA implements independent left/right asynchronous ports with separate address, control, and I/O buses, enabling concurrent read/write operations to any memory location. Its on-chip arbitration logic resolves port conflicts via open-drain BUSY outputs (BUSYL/BUSYR) that assert when both ports access the same address-requiring external 270Ω pull-ups per BUSY line.
It supports two operational modes: standalone 8-bit dual-port operation or master–slave expansion (with IDT7142) for 16-bit+ word widths. The device enters low-power standby (ISB3 ≤ 1.0 mA typ.) when CE is deasserted, and retains data at VCC = 2.0 V (LA version only), meeting MIL-PRF-38535 Class V requirements for -55°C to +125°C operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 2,048 × 8 bits (2K × 8), fully random-access dual-port SRAM |
| Access Time (max) | 25 ns (military grade, 5V, -55°C to +125°C) - defines minimum cycle time for reliable read/write |
| Supply Voltage | 5.0 V ±10% - single-rail TTL-compatible interface; no level-shifting required |
| Operating Temperature | -55°C to +125°C - qualified per MIL-PRF-38535 QML Class V for flight-critical systems |
| Standby Current (ISB3) | 1.0 mA typical (both ports fully disabled, CMOS inputs) - enables ultra-low-power hold mode |
| Data Retention Voltage | 2.0 V (LA variant only) - maintains stored data during brownout or backup-battery operation |
| Package | 48-lead flatpack (FP48), hermetically sealed, leadless ceramic - radiation-tolerant, high-reliability mounting |
Pinout & Package
5962-8700202ZA is supplied in a 48-lead flatpack (FP48) package: 0.75″ × 0.75″ × 0.11″ body, side-brazed ceramic construction, compliant with MIL-STD-883 test methods and suitable for high-vibration aerospace environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 24) | Ground reference | Must be connected to system ground plane; dual GND pins reduce ground bounce in high-speed dual-port switching |
| VCC (Pin 25) | Power supply | 5.0 V ±10% primary supply; all VCC pins must be decoupled locally with 0.1 µF ceramic + 10 µF tantalum |
| CEL / CER | Chip enable (left/right) | Active-low enables respective port; controls power-down entry (ISB1/ISB3) and arbitration sensitivity |
| OEL / OER | Output enable (left/right) | Active-low enables I/O drivers; high-Z state prevents bus contention during multi-port sharing |
| R/WL / R/WR | Read/write control (left/right) | Active-low write; determines direction of data flow on I/O lines during enabled cycles |
| BUSYL / BUSYR | Busy flag (left/right) | Open-drain outputs (IDT7132 master); require 270Ω pull-up to VCC; signal port contention for arbitration |
| A0L–A10L / A0R–A10R | Address inputs (left/right) | 11-bit address buses (2048 locations); asynchronous to each other; no inter-port synchronization required |
| I/O0L–I/O7L / I/O0R–I/O7R | Data I/O (left/right) | Bidirectional 8-bit data buses; high-impedance when OE or CE inactive; support byte-wide or full-word transfers |
Key Features
| Feature | Design Value |
|---|---|
| On-chip port arbitration logic | Resolves simultaneous same-address access without external logic; guarantees one port wins via tAPS ≥5 ns setup |
| Open-drain BUSY outputs with defined timing | BUSYL/BUSYR assert within 20 ns (tBAA) of address/CE match; eliminates need for discrete AND gates in width-expanded arrays |
| 2V data retention (LA variant) | Maintains stored contents during main power loss using backup battery; validated at TA = +25°C, ICCDR ≤ 4 µA typ. |
| QML-38535 Class V qualification | Fully screened per MIL-PRF-38535: radiation hardness assurance, lot traceability, burn-in, and extended life testing for space/avionics use |
| Dual independent power-down control | Per-port CE gating enables asymmetric standby-e.g., left port active while right port draws <1 µA (ISB4) |
Applications
| Avionics Flight Control Buffer | Radar Signal Processing Memory |
|---|---|
Use Scenario: Real-time buffering of sensor fusion data between inertial measurement unit (IMU) and flight control computer in fly-by-wire systems. IC Role / Device Role / Timing Role: Dual-port SRAM acts as synchronized handshake buffer-left port accepts IMU packet writes while right port feeds control algorithm reads at 25 ns latency. Use Value: Eliminates software polling or FIFO overflow risk; BUSY arbitration ensures deterministic response to concurrent access during transient maneuvers. |
Use Scenario: Storing intermediate FFT coefficients during pulse-Doppler radar processing in airborne early warning platforms. IC Role / Device Role / Timing Role: Master IDT7132 coordinates parallel write (ADC stream) and read (DSP engine) operations across shared memory space with guaranteed atomicity. Use Value: Enables zero-wait-state pipelining; 25 ns access sustains >40 MSPS throughput without DMA stalls or cache coherency overhead. |
| Secure Crypto Key Storage | Tactical Data Link Interface |
Use Scenario: Tamper-resistant storage of cryptographic keys and session tokens in Type 1 encryption modules deployed in field radios. IC Role / Device Role / Timing Role: LA variant provides 2V data retention during battery-switchover; dual-port isolation prevents key leakage via side-channel timing analysis. Use Value: Meets NSA-certified power-fail integrity requirements; QML-38535 screening ensures resistance to ionizing radiation and thermal shock. |
Use Scenario: Interfacing Link 16 TADIL-B message buffers between mission computer and radio transceiver in fighter jet avionics bays. IC Role / Device Role / Timing Role: Acts as protocol-agnostic message queue-left port receives parsed packets, right port supplies formatted frames to RF stack. Use Value: Flatpack package withstands 20 g vibration; dual-port concurrency avoids message loss during high-priority priority interrupts (e.g., missile launch warning). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8700201XA | Same FP48 package and 25ns speed, but commercial-grade (MIL-STD-883 Class B), not QML-38535 qualified | Lacks radiation tolerance, burn-in, and lot traceability required for flight hardware | Select only for ground-test fixtures or non-safety-critical subsystems where cost drives qualification relaxation |
| 5962-9312901MXA | 2K × 8 dual-port, 35ns access, PLCC-52 package; supports same BUSY arbitration but wider footprint and different thermal profile | PLCC packaging limits board-level reliability in high-vibration environments; no 2V retention mode | Use when legacy PLCC layout exists and MIL-PRF-38535 Class V is not mandated; verify mechanical mounting compliance |
Compared with 5962-8700202ZA, the 5962-8700201XA omits QML screening and radiation assurance, while the 5962-9312901MXA trades flatpack ruggedness for PLCC serviceability-neither offers identical combination of 25ns timing, 2V retention, and Class V qualification.
