Product details
Overview
5962-9166203MXA from Integrated Device Technology (IDT) is a military-grade, high-speed 4K × 16 dual-port static RAM with independent left/right asynchronous ports, 20 ns max access time, on-chip semaphore arbitration, and full hardware BUSY flag support for master/slave cascading in 32-bit+ systems - deployed in avionics data buffers and real-time radar signal processors.
For engineers reviewing the 5962-9166203MXA datasheet, 5962-9166203MXA pinout, 5962-9166203MXA application, or 5962-9166203MXA equivalent, key selection criteria include MIL-PRF-38535 QML compliance, -55°C to +125°C operation, dual-port contention resolution timing (tBDD ≤ 30 ns), battery-backed 2V data retention, and 84-pin ceramic PGA package compatibility with legacy defense PCB layouts.
Technical Context
The 5962-9166203MXA implements true dual-ported SRAM cells enabling simultaneous reads of identical addresses across ports, with fully asynchronous operation and separate upper/lower byte enables (UBL/UBR, LBL/LBR) for multiplexed bus interfacing. Its arbitration logic resolves port conflicts via hardware semaphore flags (A0–A2 addressable) and BUSY signaling.
As a military-grade variant of the IDT7024 family, it supports M/S-selectable master/slave configuration: BUSY is output on master (M/S = H), input on slave (M/S = L); interrupt flags (INTL/INTR) provide cross-port event notification, and all control signals (CE, R/W, OE, SEM) operate at TTL-compatible levels with 5.0 V ±10% supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
5962-9166203MXA is packaged in an 84-pin ceramic Pin Grid Array (GU84) with 0.100" pin pitch, hermetic seal, and MIL-STD-883 qualification. All VCC pins require local decoupling; all GND pins must be connected to system ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A11L / A0R–A11R | Left/Right Port Address Inputs | 12-bit independent addressing per port; no inter-port address dependency |

| SEML / SEMR | Semaphore Enable | Activates 8-flag semaphore register (A0–A2 addressed); enables inter-processor synchronization |
| BUSYL / BUSYR | Busy Flag (Master Output / Slave Input) | When M/S = HIGH: BUSYR outputs contention status; when M/S = LOW: BUSYL accepts external BUSY |
| INTL / INTR | Interrupt Flag Output | Open-collector push-pull output signals semaphore or write completion events to host CPU |
| M/S | Master/Slave Select | Configures device role in cascaded systems; determines BUSY pin direction and arbitration priority |

Applications
| Avionics Flight Control Buffer | Tactical Radar Signal Processor |
|---|---|
|
Use Scenario: Real-time exchange of sensor fusion data between flight control computer (FCC) and inertial measurement unit (IMU) over dual synchronous buses. IC Role / Device Role / Timing Role: Dual-port RAM acts as time-deterministic shared memory buffer with hardware arbitration preventing race conditions during rapid attitude updates. Use Value: 20 ns access time ensures sub-millisecond loop closure; BUSY flag coordination eliminates polling overhead in safety-critical FCC firmware. |
Use Scenario: Storing intermediate FFT results between radar front-end ADC and DSP engine in airborne SAR systems. IC Role / Device Role / Timing Role: Left port receives digitized samples from ADC; right port feeds processed data to DSP - fully asynchronous, zero-wait-state operation. Use Value: 4K × 16 organization matches common radar pulse bin depth; -55°C to +125°C rating ensures reliability in uncooled pod environments. |
| Secure Communication Crypto Engine | Missile Guidance Onboard Computer |
|
Use Scenario: Key scheduling and round-state storage in AES-256 encryption module with separate host interface and crypto core access. IC Role / Device Role / Timing Role: Host CPU writes plaintext/key via one port; crypto accelerator reads/writes round states via second port - isolated memory domains. Use Value: Hardware semaphore flags coordinate key loading without software intervention; 2V data retention preserves keys during brownout events. |
Use Scenario: Storing navigation solution vectors and guidance command tables in hardened missile onboard computer with dual redundant processors. IC Role / Device Role / Timing Role: Dual CPUs access shared trajectory database via master/slave configuration - one CPU masters BUSY arbitration while other executes guidance law. Use Value: GU84 ceramic PGA withstands shock/vibration per MIL-STD-810; QML Class V screening ensures mission-critical uptime in terminal phase. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C024AV-20AXC | Commercial-grade (0°C to +70°C), 100-pin TQFP, no MIL-PRF-38535 qualification | Lacks radiation tolerance, thermal range, and hermetic packaging - unsuitable for flight-critical systems | Select only for ground-based test equipment or non-safety-critical prototypes |
| AS7C34096B-20BIN | Industrial-grade (-40°C to +85°C), 100-pin TQFP, lower standby current (0.1 mA), but no BUSY/M/S logic | No hardware arbitration or master/slave cascading - requires external logic for multi-processor sync | Use where cost and power dominate over deterministic contention resolution |
Compared with CY7C024AV-20AXC and AS7C34096B-20BIN, the 5962-9166203MXA uniquely delivers QML Class V reliability, hardware BUSY arbitration, and military temperature operation in a single monolithic device - eliminating system-level complexity in certified airborne platforms.

FAQ
What is the guaranteed maximum access time for 5962-9166203MXA across its full military temperature range?
The 5962-9166203MXA guarantees a maximum access time of 20 ns over the full -55°C to +125°C operating range, as validated per MIL-PRF-38535 QML Class V testing. This value applies to both tAA (address access) and tACE (chip enable access) under worst-case voltage (5.5 V) and temperature conditions, ensuring deterministic timing in hard real-time avionics applications.
Does 5962-9166203MXA support true simultaneous read operations from both ports to the same memory address?
Yes, the 5962-9166203MXA implements true dual-ported SRAM cells that allow concurrent reads from identical addresses on left and right ports without contention or data corruption. This capability is intrinsic to the cell architecture - not dependent on arbitration logic - and is explicitly confirmed in the functional description and truth tables of the official IDT7024 datasheet.
How does the M/S pin configure arbitration behavior in a multi-device 5962-9166203MXA system?
When M/S = HIGH, the 5962-9166203MXA operates as master: BUSYR outputs a contention flag to downstream slaves, and it asserts priority during simultaneous address access. When M/S = LOW, it operates as slave: BUSYL accepts BUSY input from upstream master and defers writes until BUSY deasserts. This hierarchical scheme enables scalable 32-bit+ word expansion without external logic.
What is the minimum supply voltage required to retain data in 5962-9166203MXA during power loss?
The 5962-9166203MXA retains stored data down to 2.0 V on VCC, as specified in the Data Retention Characteristics table (VDR = 2.0 V min). At this voltage, typical retention current is 100 µA, enabling reliable holdover using a small backup battery or supercapacitor - a critical feature for maintaining flight state during main power interruption.
Is the 5962-9166203MXA pinout compatible with other IDT7024 variants such as 5962-9166202MXA or commercial 7024S/L parts?
Yes, the 5962-9166203MXA shares identical pinout, signal naming, and electrical interface with all IDT7024 family members in the 84-pin GU84 PGA package, including 5962-9166202MXA (25 ns variant) and commercial 7024S/L derivatives. Functionally identical control logic, timing parameters, and register mapping ensure drop-in replacement within the same speed grade and package footprint.
