Product details
Overview
7024S17G from IDT is a high-speed 4K × 16 true dual-port static RAM with independent left/right ports, 17 ns maximum read cycle time (commercial grade), on-chip semaphore and arbitration logic, and TTL-compatible 5V ±10% operation - used in real-time inter-processor communication, video frame buffers, and military-grade avionics data exchange systems.
For engineers reviewing the 7024S17G datasheet, 7024S17G pinout, 7024S17G application, or 7024S17G equivalent, this page delivers verified timing specs, master/slave port arbitration behavior, battery-backed data retention at 2V, and precise pin-level I/O byte control for multiplexed bus integration.
Technical Context
The 7024S17G implements fully asynchronous dual-port access with separate address, control, and bidirectional I/O buses per port - enabling simultaneous reads of identical memory locations without contention. Its on-chip arbitration logic resolves port conflicts via BUSY flag signaling and supports both master (BUSY output) and slave (BUSY input) configurations through the M/S pin.
It integrates full hardware semaphore support across eight flags (addressed by A0–A2), with dedicated SEM, INT, and BUSY signals per port. The device operates in two distinct modes: RAM access (SEM = VIH) and semaphore register access (SEM = VIL), each with separate timing requirements and signal dependencies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 4K × 16 bits (64 Kbit total); enables 32-bit+ word expansion via master/slave cascading |
| Access Time (tRC) | 17 ns max (commercial grade); defines minimum read cycle interval for guaranteed valid data |
| Supply Voltage | 5.0 V ±10%; compatible with standard TTL logic families without level-shifting |
| Data Retention | 2 V minimum; allows battery backup operation with ≤4 mA standby current (7024L variant) |
| Operating Temperature | 0°C to +70°C (commercial); validated for stable timing and arbitration across full range |
| Power Consumption | Active: 170 mA typ (7024S); Standby (ISB1): 20 mA typ - critical for thermal management in dense PCB layouts |
| Package | 100-pin Thin Quad Flatpack (TQFP); 14 mm × 14 mm footprint with 0.5 mm pitch for high-density routing |
Pinout & Package
7024S17G is packaged in a 100-pin TQFP (PNG100) with 0.5 mm pitch, 14 mm × 14 mm body, and 1.4 mm height - optimized for automated assembly and thermal dissipation in industrial control modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CEL / CER | Chip Enable (Left/Right) | Independent port activation; deasserting either disables its internal circuitry and forces I/O into high-Z |
| R/WL / R/WR | Read/Write Control (Left/Right) | Active-low write enable; controls direction of data flow on respective port's I/O bus |
| OEL / OER | Output Enable (Left/Right) | Separates read-data gating from chip select; allows CE-driven power-down while maintaining output control |
| UBL / UBR, LBL / LBR | Upper/Lower Byte Select | Enables independent 8-bit access per port - essential for multiplexed 16-bit bus compatibility and partial writes |
| SEML / SEMR | Semaphore Enable | Switches port between RAM array (SEM = VIH) and 8-flag semaphore register (SEM = VIL) |
| BUSYL / BUSYR | Busy Flag (Master Output / Slave Input) | When M/S = H, BUSY is driven to indicate port contention; when M/S = L, BUSY is sampled to block writes |
| INTL / INTR | Interrupt Flag | Open-drain push-pull output signaling semaphore state change or arbitration event to host processor |
| A0L–A11L / A0R–A11R | Address Inputs | 12-bit address per port (4K depth); non-mirrored - left and right ports access same physical memory space |
| I/O0L–I/O15L / I/O0R–I/O15R | Bidirectional Data Bus | 16-bit parallel interface per port; supports simultaneous read/write to same location (true dual-port cell architecture) |
Key Features
| Feature | Design Value |
|---|---|
| True Dual-Port Memory Cells | Enables concurrent read operations from both ports to identical addresses - eliminates arbitration delay in real-time buffer sharing |
| On-Chip Port Arbitration Logic | Resolves simultaneous access conflicts via BUSY flag assertion without external glue logic - reduces BOM count and layout complexity |
| Full Hardware Semaphore Support | Eight dedicated flags (A0–A2 addressed) with atomic read/write and contention window (tSPS = 5 ns) - ensures deterministic inter-process synchronization |
| Separate Byte Enables (UB/LB) | Allows independent upper/lower byte writes per port - critical for mixed-endian systems and legacy 8-bit peripheral interfacing |
| Battery Backup Data Retention | Maintains stored data at 2 V supply (7024L variant); supports fail-safe state preservation during main power loss |
| Industrial & Military Temp Options | Validated operation from –40°C to +85°C (industrial) and –55°C to +125°C (military) - qualified per MIL-PRF-38535 QML |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C1370D-167AXC | 167 MHz (6 ns tRC), 8K × 18 organization, 3.3 V core with 5 V tolerant I/O | Higher bandwidth but incompatible voltage and data width; requires level shifters and bus-width adaptation | Select when migrating to faster, wider memory with modern low-voltage FPGAs - not drop-in compatible with 7024S17G designs |
| AS7C34098B-15JCN | 15 ns tRC, 4K × 16, 3.3 V only, no built-in semaphore or BUSY arbitration logic | Lacks hardware arbitration and semaphore - demands external logic or software coordination for multi-processor use | Choose for cost-sensitive commercial systems where arbitration is handled in firmware and 5 V tolerance is unnecessary |
Compared with CY7C1370D-167AXC and AS7C34098B-15JCN, the 7024S17G uniquely delivers 5 V TTL compatibility, integrated master/slave arbitration, and hardware semaphores - making it irreplaceable in legacy avionics and industrial control systems requiring zero-modification interoperability.

FAQ
What is the maximum operating speed of the 7024S17G?
The 7024S17G has a maximum read cycle time (tRC) of 17 ns, corresponding to a theoretical maximum throughput of approximately 58.8 MHz for consecutive reads. This speed is guaranteed over the commercial temperature range (0°C to +70°C) with 5.0 V ±10% supply and meets all AC timing parameters in the official IDT datasheet revision dated Feb. 20, 2020.
Does the 7024S17G support battery backup operation?
Yes - the 7024S17G (specifically the 'L' variant suffix, as in 7024L17G) supports data retention at VCC = 2.0 V with typical ICCDR of 100 µA. While the 7024S17G is the speed-graded commercial version, its underlying design inherits the 2 V retention capability from the IDT7024L family; actual retention current depends on ambient temperature and package type.
How does master/slave configuration work on the 7024S17G?
The M/S pin configures port behavior: when high, the device operates as Master - driving BUSYR/BUSYL as outputs to signal contention; when low, it acts as Slave - sampling BUSYR/BUSYL as inputs to inhibit writes. This enables cascaded multi-device systems where one 7024S17G coordinates arbitration for several slaves without external logic.
What is the function of the SEM pin on the 7024S17G?
The SEM (Semaphore Enable) pin selects between two operational modes: when SEM = VIH, the port accesses the 4K × 16 RAM array; when SEM = VIL, it accesses an 8-bit semaphore register (addressed by A0–A2). This dual-mode architecture enables atomic flag manipulation without disturbing main memory contents - critical for deadlock-free inter-processor synchronization.
Which package types are available for the 7024S17G?
The 7024S17G is offered in a 100-pin Thin Quad Flatpack (TQFP, package code PNG100) with 0.5 mm pitch and 14 mm × 14 mm body. Although the IDT7024 family also supports PGA, Flatpack, and PLCC variants, the 'G' suffix in 7024S17G explicitly denotes the TQFP package per IDT's ordering guide and datasheet footnote 4.
