Product details
Overview
7024L17G from IDT is a high-speed 4K × 16 true dual-port static RAM with independent left/right ports, 17 ns maximum access time (commercial grade), 2V data retention capability, and full on-chip semaphore arbitration logic-designed for real-time inter-processor communication in embedded control systems.
For engineers reviewing the 7024L17G datasheet, 7024L17G pinout, 7024L17G application, or 7024L17G equivalent, key selection criteria include dual-port contention resolution timing (tBDD ≤ 18 ns), low standby power (1 mW typ.), battery-backed operation, and Master/Slave cascading support for 32-bit+ bus expansion.
Technical Context
The 7024L17G implements fully asynchronous dual-port architecture with separate address, control, and I/O buses per port, enabling simultaneous read/write operations-even to the same memory location. Its on-chip arbitration logic resolves port conflicts via BUSY flag signaling and supports both Master (BUSY output) and Slave (BUSY input) configurations.
It integrates full hardware semaphore signaling across ports using A0–A2 addressing and I/O0 for flag write, with dedicated SEM, INT, and BUSY terminals. The device operates at 5.0 V ±10% with TTL-compatible inputs and supports battery backup down to 2 V for data retention without external circuitry.

Pinout & Package
7024L17G is packaged in an 84-pin PLCC (PLG84) with 0.050" lead pitch and 1.15" × 1.15" body size. All VCC and GND pins require decoupling per layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A11L | Left-port address inputs | 12-bit address bus for left-side memory access; independent of right-port addressing |
| A0R–A11R | Right-port address inputs | Enables concurrent addressing of same or different locations by two processors |
| I/O0L–I/O15L | Left-port bidirectional data | 16-bit data path; byte-selectable via UBL/LBL for partial writes |

| INTL / INTR | Interrupt flag (left/right) | Open-drain push-pull output signals semaphore or arbitration events to host processor |
| BUSYL / BUSYR | Busy flag (left/right) | When M/S = H (Master), BUSY is output indicating port contention; when M/S = L (Slave), BUSY is input for synchronization |
| M/S | Master/Slave select | Configures device role in cascaded systems; determines BUSY signal direction and arbitration priority |
| UBL / UBR | Upper-byte select (left/right) | Enables 8-bit upper data lane (I/O8–I/O15); supports byte-wide transfers on multiplexed buses |
| LBL / LBR | Lower-byte select (left/right) | Enables 8-bit lower data lane (I/O0–I/O7); allows independent byte writes without masking logic |
Key Features
| Feature | Design Value |
|---|---|
| True dual-port memory cells | Enables simultaneous reads/writes to identical addresses-eliminates software polling or lock-step coordination |
| On-chip semaphore logic | Hardware-managed 8-flag semaphore bank (A0–A2 addressed) reduces CPU overhead in multi-processor resource sharing |

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 | 2.5 V core / 3.3 V I/O; 167 MHz QDR interface; no native BUSY arbitration | Requires external logic for contention management; suited for high-bandwidth cache, not real-time IPC | Choose for higher throughput in non-contention scenarios; avoid where deterministic arbitration is required |
| IS61WV25616EDBLL-10MLI | Single-port SDRAM; 10 ns access; no dual-port or semaphore logic | Lacks hardware inter-processor sync; requires software-managed buffers and polling | Select only if cost sensitivity outweighs determinism needs; adds firmware complexity and latency |
Compared with CY7C1370D-167AXC and IS61WV25616EDBLL-10MLI, the 7024L17G uniquely delivers integrated BUSY-based arbitration and battery-retained dual-port operation-making it irreplaceable for safety-critical, low-latency inter-processor communication where hardware-enforced mutual exclusion is mandatory.

FAQ
What is the maximum operating speed of the 7024L17G?
The 7024L17G has a maximum access time of 17 ns under commercial temperature conditions (0°C to +70°C), corresponding to a read cycle time (tRC) of 17 ns. This enables reliable operation with system clocks up to approximately 58.8 MHz when interfaced with appropriate setup/hold timing margins. The device does not specify a maximum clock frequency but guarantees timing compliance at this access limit.
Does the 7024L17G support battery backup operation?
Yes, the 7024L17G supports battery backup operation with guaranteed data retention at VCC = 2.0 V minimum. In this mode, standby current drops to 1 mW typical, allowing extended retention from a small backup cell without external regulators or switching circuitry-critical for applications like avionics or industrial controllers requiring state preservation during main power loss.
How does the Master/Slave configuration work on the 7024L17G?
The M/S pin configures the 7024L17G as either Master (M/S = HIGH) or Slave (M/S = LOW). In Master mode, BUSY is an output flag indicating port contention; in Slave mode, BUSY is an input used to synchronize writes. This enables cascaded configurations where one device arbitrates access for multiple slaves-essential for expanding data bus width beyond 16 bits without external logic.
What is the function of the semaphore logic in the 7024L17G?
The 7024L17G includes eight hardware semaphore flags accessible via A0–A2 addressing and controlled through SEML/SEMR. Writing to I/O0 sets a flag; reading returns its state across all 16 I/O lines. This offloads inter-processor synchronization from software-reducing latency and eliminating race conditions in multi-CPU systems such as PLCs or radar processors.
Which package types are available for the 7024L17G?
The 7024L17G is offered in an 84-pin PLCC (PLG84) package with 1.15" × 1.15" footprint and 0.050" lead pitch. While the IDT7024 family also includes PGA, Flatpack, and TQFP variants, the 7024L17G ordering code specifically corresponds to the PLCC version-verified by IDT documentation and distributor listings for this speed/temp grade.
