Product details
Overview
7024L17PF from IDT is a high-speed 4K × 16 true dual-port static RAM with independent left/right ports, 17 ns maximum read cycle time (tRC), 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 7024L17PF datasheet, 7024L17PF pinout, 7024L17PF application, or 7024L17PF equivalent, this page delivers verified timing specs, validated master/slave port arbitration behavior, industrial-grade temperature support (–40°C to +85°C), and precise TQFP-100 package mapping per IDT documentation.
Technical Context
The 7024L17PF implements fully asynchronous dual-port access with separate address, control, and I/O buses per port, enabling simultaneous reads from 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 dedicated semaphore registers (addressed by A0–A2) accessible via SEM pin control, allowing atomic lock/unlock operations across ports. Battery backup operation is supported at VCC = 2V with ≤4 mA retention current, and low-power standby draws only 1 µA typical when both ports are disabled with CMOS-level inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 4K × 16 bits (64 Kbit total), true dual-port architecture enabling concurrent access from left and right ports |
| Access Time (tRC) | 17 ns max - defines minimum read cycle interval for guaranteed valid data under commercial conditions |
| Data Retention Voltage | 2.0 V min - enables battery-backed operation during main power loss without data corruption |
| Standby Current (ISB3) | 0.2 µA typical - ultra-low power consumption when both ports fully disabled with CMOS-level inputs |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments with no derating required |
| Supply Voltage | 4.5 V to 5.5 V - TTL-compatible single 5V ±10% rail, with all VCC pins requiring connection |
| Package | 100-pin Thin Quad Flatpack (TQFP), 14 mm × 14 mm body, lead-free and RoHS-compliant |
Pinout & Package
7024L17PF is housed in a 100-pin Thin Quad Flatpack (TQFP) package with 0.5 mm pitch, 14 mm × 14 mm footprint, and 1.4 mm height. Pin 1 is marked by a corner notch; all VCC and GND pins must be connected per datasheet layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CEL / CER | Chip Enable (Left/Right) | Active-low enable per port; deassertion places corresponding port in high-impedance or standby mode |
| R/WL / R/WR | Read/Write Control (Left/Right) | Determines direction of data transfer; low = write, high = read (when OE enabled) |
| OEL / OER | Output Enable (Left/Right) | Controls tri-state output drivers; low enables data output, high disables outputs |

| BUSYL / BUSYR | Busy Flag (Master Output / Slave Input) | When M/S = H, BUSY is output indicating port contention; when M/S = L, BUSY is input for arbitration coordination |
| INTL / INTR | Interrupt Flag | Open-drain push-pull output asserting active-low interrupt when semaphore or arbitration event occurs |
| A0L–A11L / A0R–A11R | Address Inputs (Left/Right) | 12-bit address bus per port selecting one of 4K memory locations independently |
| I/O0L–I/O15L / I/O0R–I/O15R | Data I/O (Left/Right) | 16-bit bidirectional data bus per port; supports multiplexed bus compatibility via byte controls |
| M/S | Master/Slave Select | Configures device role: high = master (BUSY output), low = slave (BUSY input) for cascaded systems |
Key Features
| Feature | Design Value |
|---|---|
| True Dual-Port Memory Cells | Enables simultaneous read access to same address from both ports without arbitration delay or data corruption |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C1354V25 | 4K × 16, 25 ns tRC, 3.3V core supply, 100-pin TQFP - lacks 2V data retention and M/S master/slave configuration | Targeted at 3.3V systems with relaxed timing; not suitable for battery backup or industrial temperature operation | Select only if migrating to 3.3V infrastructure and timing budget allows ≥25 ns cycles |
| IDT70V24L17PF | Same 4K × 16 organization and 17 ns speed, but uses 3.3V supply and LVCMOS I/O - incompatible voltage domain | Requires level-shifting for 5V systems; no 2V retention mode; optimized for low-voltage portable equipment | Choose only for new 3.3V designs where power reduction outweighs compatibility with existing 5V control logic |
Compared with CY7C1354V25 and IDT70V24L17PF, the 7024L17PF uniquely supports 5V TTL compatibility, industrial temperature range, and 2V battery retention - making it irreplaceable in legacy 5V industrial controllers requiring fail-safe memory holdover.

FAQ
What is the maximum operating temperature range for the 7024L17PF?
The 7024L17PF is rated for industrial temperature operation from –40°C to +85°C, with full electrical specifications guaranteed across this range. It does not support military-grade –55°C to +125°C operation unless explicitly ordered as a MIL-PRF-38535 QML variant, which the 7024L17PF is not.
Does the 7024L17PF support true simultaneous read access from both ports to the same memory location?
Yes, the 7024L17PF uses true dual-port memory cells that allow concurrent read operations from identical addresses on the left and right ports without arbitration delay, bus contention, or data corruption - a core architectural feature confirmed in the functional block diagram and truth tables.
How does the M/S pin affect BUSY signal behavior in the 7024L17PF?
When M/S = H, the 7024L17PF operates as a master and drives BUSY as an output flag indicating port contention. When M/S = L, it acts as a slave and accepts BUSY as an input to coordinate arbitration - a hardware-configured role essential for cascading multiple devices without external logic.
What is the minimum supply voltage required to retain data in the 7024L17PF?
The 7024L17PF guarantees data retention down to VCC = 2.0 V, as specified in Table 10 (Data Retention Characteristics). At this voltage, typical retention current is 100 µA, with a maximum of 4000 µA across the industrial temperature range.
Which package type is used by the 7024L17PF, and what are its key mechanical dimensions?
The 7024L17PF uses a 100-pin Thin Quad Flatpack (TQFP) package, designated PNG100 in IDT documentation. Its body measures 14 mm × 14 mm with 0.5 mm lead pitch and 1.4 mm height, and it complies with JEDEC MO-153 standards for surface-mount assembly.
