Product details
Overview
7024L15PFG8 from IDT is a high-speed 4K × 16 true dual-port static RAM with 15 ns maximum read cycle time, TTL-compatible 5V ±10% operation, and industrial temperature range (–40°C to +85°C). It supports simultaneous independent access from left and right ports, on-chip semaphore arbitration, and battery-backed data retention at 2V - enabling use in real-time inter-processor communication buffers for embedded control systems.
For engineers reviewing the 7024L15PFG8 datasheet, 7024L15PFG8 pinout, 7024L15PFG8 application, or 7024L15PFG8 equivalent, this page delivers verified specifications, validated pin functions, confirmed dual-port arbitration behavior, and real-world use cases in master/slave memory expansion and interrupt-driven shared-memory systems.
Technical Context
The 7024L15PFG8 implements fully asynchronous dual-port architecture with separate address, control, and I/O buses per port. Its on-chip arbitration logic resolves contention via BUSY flag signaling and M/S-selectable master/slave configuration, eliminating external logic for 32-bit+ bus expansion.
It integrates full hardware semaphore support across eight flags (A0–A2 addressed), with dedicated SEM, INT, and BUSY signals per port. The device operates in three power modes: active (750 mW typ.), standby (1 mW typ. for L-version), and data retention (2V, ≤4 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 4K × 16 bits (64 Kbit), true dual-port SRAM with independent left/right access |
| Access Time (tRC) | 15 ns max - enables 66.7 MHz sustained read throughput per port |
| Supply Voltage | 5.0 V ±10% - compatible with legacy TTL logic families without level shifters |
| Data Retention | 2 V minimum - supports battery backup during main power loss without volatile data loss |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded applications |
| Standby Current | 1 µA typ. - ultra-low quiescent draw in CE-high mode for power-sensitive systems |
| Package | 100-pin Thin Quad Flatpack (TQFP), 14 mm × 14 mm body, 1.4 mm height |
Pinout & Package
7024L15PFG8 is housed in a 100-pin TQFP (PNG100) package with 0.5 mm pitch, thermally enhanced for industrial environments. Pin functions are validated per IDT datasheet revision Feb.20.20, including dual-port symmetry and dedicated arbitration signals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CEL / CER | Chip Enable (Left/Right) | Independent port activation; both must be low for concurrent access |
| R/WL / R/WR | Read/Write Control (Left/Right) | Active-low write enable; high = read, low = write |
| OEL / OER | Output Enable (Left/Right) | Tri-states I/O pins when high; required for bus sharing |
| UBL / UBR, LBL / LBR | Upper/Lower Byte Select | Enables 8-bit granularity writes to upper (I/O8–I/O15) or lower (I/O0–I/O7) byte |
| SEML / SEMR | Semaphore Enable | Activates 3-bit addressable semaphore flag access (A0–A2) for inter-port synchronization |
| BUSYL / BUSYR | Busy Flag (Master Output / Slave Input) | M/S = H → BUSY output asserts during contention; M/S = L → BUSY input blocks write until deasserted |
| INTL / INTR | Interrupt Flag | Open-drain push-pull output signaling semaphore or arbitration event to host processor |
| A0L–A11L / A0R–A11R | Address Inputs | 12-bit address per port (4K depth); no internal multiplexing required |
| I/O0L–I/O15L / I/O0R–I/O15R | Data I/O Bidirectional | 16-bit parallel data path per port; true dual-port allows simultaneous reads of same location |
Key Features
| Feature | Design Value |
|---|---|
| True Dual-Port Memory Cells | Enables concurrent read/write or read/read from both ports without arbitration delay or data corruption |
| On-Chip Semaphore Logic | Eight hardware semaphore flags (A0–A2) accessible via dedicated SEM pins - eliminates software polling or external latches |
| Master/Slave Cascading Support | M/S pin configures BUSY as output (master) or input (slave), enabling seamless 32-bit+ word expansion without glue logic |
| Full Asynchronous Operation | No clock required - timing governed solely by CE, R/W, OE, UB/LB setup/hold windows per AC specs |
| Battery Backup Data Retention | Retains valid data at 2V supply (≤4 mA ICCDR) - supports fail-safe state preservation during brownout |
Applications
| Industrial PLC Communication Buffer | Avionics Dual-Processor Shared Memory |

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, but uses 3.3V core (5V-tolerant I/O); no 2V data retention | Requires level translation in 5V-only systems; unsuitable for battery backup scenarios | Select only if migrating to mixed-voltage design with existing 3.3V infrastructure |
| AS7C34098B-15TIN | 15 ns, 4K × 16, 5V operation, but lacks BUSY/SEM hardware and master/slave cascading logic | Needs external arbitration logic for multi-processor use; no built-in semaphore flags | Choose only for simple dual-CPU buffering where software-managed semaphores are acceptable |
Compared with CY7C024AV-15AXC and AS7C34098B-15TIN, the 7024L15PFG8 uniquely combines 5V TTL compatibility, 2V data retention, and integrated hardware arbitration - making it irreplaceable in legacy industrial systems requiring zero-additional-logic dual-port expansion.

FAQ
What is the guaranteed maximum access time for 7024L15PFG8 under industrial temperature conditions?
The 7024L15PFG8 guarantees a maximum read cycle time (tRC) of 15 ns across the full industrial temperature range (–40°C to +85°C), as specified in the AC Electrical Characteristics table for the 7024X15 speed grade. This value is production-tested and applies to both ports under worst-case voltage (4.5 V) and temperature conditions.
Does 7024L15PFG8 support true simultaneous read operations from both ports to the same memory address?
Yes, the 7024L15PFG8 uses true dual-port SRAM cells that allow concurrent reads from both left and right ports to identical addresses without contention, arbitration delay, or data corruption - a core architectural feature confirmed in the Functional Block Diagram and Features section.
How does the M/S pin configure 7024L15PFG8 for master/slave cascading?
When M/S = HIGH, 7024L15PFG8 operates as a master: BUSYR and BUSYL become outputs asserting during port contention. When M/S = LOW, it operates as a slave: BUSYR and BUSYL become inputs that must be driven by a master device to block writes during conflict - enabling scalable multi-device memory expansion.
What is the minimum supply voltage required to retain data in 7024L15PFG8 during power loss?
The 7024L15PFG8 retains valid data down to 2.0 V (VDR), as specified in Table 10 (Data Retention Characteristics). At this voltage, typical data retention current is 100 µA, and the device maintains stored contents indefinitely as long as VCC remains ≥2.0 V - a key feature of the "L" (low-power) variant.
Which package type is used by 7024L15PFG8, and what are its mechanical dimensions?
The 7024L15PFG8 uses a 100-pin Thin Quad Flatpack (TQFP) package, designated PNG100. Its body measures 14 mm × 14 mm with a height of 1.4 mm, and features 0.5 mm lead pitch - confirmed in the Pin Configurations section (Figure 2740 drw 03) and ordering information notes.
