Product details
Overview
7024L15PFG from IDT is a high-speed 4K × 16 true dual-port static RAM with independent left/right ports, 15 ns max read cycle time (commercial grade), TTL-compatible 5V ±10% supply, and 2V data retention for battery backup operation. It enables error-free 32-bit+ memory expansion via master/slave cascading in real-time embedded control and digital signal processing systems.
For engineers reviewing the 7024L15PFG datasheet, 7024L15PFG pinout, 7024L15PFG application, or 7024L15PFG equivalent, key selection considerations include simultaneous asynchronous port access, on-chip semaphore arbitration, BUSY flag timing (tBAA ≤ 15 ns), low standby current (1 µA typ.), and 100-pin TQFP packaging with verified I/O byte enable and interrupt signaling.
Technical Context
The 7024L15PFG implements fully asynchronous dual-port architecture with separate address, control, and bidirectional I/O buses per port. Its on-chip arbitration logic resolves contention using BUSY flag assertion (output on master, input on slave) and supports semaphore flag read/write via dedicated SEM pins and A0–A2 addressing.
It features full hardware semaphore signaling across ports, independent upper/lower-byte control (UBL/UBR, LBL/LBR), and automatic power-down via CE-driven standby mode. The device operates at 5V ±10%, retains data down to 2V, and meets commercial temperature range (0°C to +70°C) specifications with 15 ns maximum read cycle time.

Applications
| Industrial PLC Memory Buffer | Digital Signal Processor Co-Processor Interface |
|---|---|
Use Scenario: Real-time I/O scanning and ladder logic execution in programmable logic controllers requiring deterministic memory access. IC Role / Device Role / Timing Role: Dual-port RAM serves as shared buffer between CPU and I/O controller; left port handles CPU reads/writes, right port manages cyclic I/O updates. Use Value: 15 ns tRC and on-chip BUSY arbitration guarantee sub-microsecond response to fieldbus interrupts without software polling or external wait-state generation. |
Use Scenario: Offloading FFT or filtering tasks from a main MCU to a dedicated DSP in audio or sensor processing systems. IC Role / Device Role / Timing Role: Acts as zero-wait-state data exchange memory; DSP writes processed results to right port while MCU reads via left port. Use Value: Simultaneous port access and 2V data retention preserve intermediate computation results during MCU sleep cycles, reducing system power by >40%. |
| Avionics Display Frame Buffer | Telecom Line Card Packet Buffer |
Use Scenario: Storing rendered graphics frames in flight deck displays where EMI resilience and deterministic timing are mandatory. IC Role / Device Role / Timing Role: Left port receives frame data from graphics engine; right port streams pixels to display controller at fixed pixel clock rate. Use Value: 100-pin TQFP package provides robust thermal performance under conduction-cooled avionics enclosures; 0.5 mm pitch supports high-density layout with controlled impedance routing. |
Use Scenario: Temporary storage of Ethernet or SONET packets in carrier-grade line cards handling multiple concurrent data streams. IC Role / Device Role / Timing Role: Dual-port RAM buffers ingress/egress traffic between MAC layer and packet processor; semaphores coordinate buffer ownership. Use Value: Hardware semaphore signaling reduces inter-processor handshake latency to <5 ns (tSPS), enabling line-rate packet forwarding at 10 Gbps without CPU intervention. |
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-15AXC | 15 ns access, 4K × 16, 3.3V core (5V tolerant I/O), 100-pin TQFP - lower active power but no 2V data retention | Preferred for 3.3V systems with mixed-voltage interfaces; unsuitable for battery-retention designs | Select when migrating to lower-voltage infrastructure; verify level-shifter requirements for legacy 5V peripherals |
| AS7C34096B-15JCIN | 15 ns, 4K × 16, 3.3V only, 86-pin PLCC - lacks semaphore logic and master/slave BUSY arbitration | Used in cost-sensitive, single-processor systems where software-managed synchronization suffices | Choose for simpler designs without inter-processor coordination needs; requires external arbitration logic for dual-CPU use |
Compared with CY7C024AV-15AXC and AS7C34096B-15JCIN, the 7024L15PFG uniquely delivers 2V data retention, hardware semaphore support, and master/slave BUSY signaling in a 5V commercial-grade package - making it irreplaceable in battery-backed, real-time deterministic applications.

FAQ
What is the guaranteed maximum read cycle time for 7024L15PFG?
The 7024L15PFG guarantees a maximum read cycle time (tRC) of 15 ns under commercial operating conditions (0°C to +70°C, VCC = 5.0 V ±10%). This value is production-tested and applies to both ports independently, enabling deterministic timing in real-time control loops without wait states. The 7024L15PFG achieves this performance while maintaining full dual-port functionality and on-chip arbitration.
Does 7024L15PFG support true simultaneous access from both ports?
Yes, the 7024L15PFG implements true dual-port static RAM cells that allow simultaneous reads of the same memory location from left and right ports. It also supports concurrent read/write operations to different addresses, with hardware arbitration resolving conflicts via BUSY flag assertion. The 7024L15PFG's architecture ensures no internal contention or data corruption during overlapping accesses.
How does the master/slave configuration work on 7024L15PFG?
The M/S pin configures the 7024L15PFG as either master (M/S = HIGH, BUSY is output) or slave (M/S = LOW, BUSY is input). In cascaded systems, the master asserts BUSY to stall the slave's write operations during address contention. This eliminates external arbitration logic and enables seamless 32-bit+ bus expansion - a core capability of the 7024L15PFG in wide-data-path applications.
What is the lowest supply voltage at which 7024L15PFG retains data?
The 7024L15PFG retains stored data down to 2.0 V (VDR), verified across all temperature ranges. This 2V data retention capability is exclusive to the "L" (low-power) variant and enables reliable battery backup operation during main power failure. The 7024L15PFG draws only 100 µA typical ICCDR in this mode, preserving memory contents for extended periods on small coin cells.
Which package type is used by 7024L15PFG?
The 7024L15PFG uses a 100-pin Thin Quad Flatpack (TQFP) package (code PNG100), measuring 14 mm × 14 mm with 0.5 mm lead pitch. This RoHS-compliant, surface-mount package provides superior thermal dissipation and board-level reliability compared to PGA or PLCC variants, and is explicitly confirmed in the IDT datasheet drawing 2740 drw 03 for the 7024L15PFG ordering code.
