Product details
Overview
7024L20PFGI8 from IDT is a high-speed 4K × 16 true dual-port static RAM with independent left/right ports, 20 ns max access time (industrial grade), TTL-compatible 5V ±10% supply, and on-chip semaphore arbitration logic. It enables simultaneous asynchronous reads/writes to the same memory location and supports master/slave cascading for 32-bit+ bus expansion in real-time embedded control systems.
For engineers reviewing the 7024L20PFGI8 datasheet, 7024L20PFGI8 pinout, 7024L20PFGI8 application, or 7024L20PFGI8 equivalent, key selection considerations include dual-port arbitration timing (tBDD ≤ 30 ns), battery-backed data retention at 2V, industrial temperature range (–40°C to +85°C), and 100-pin TQFP package compatibility with multiplexed bus systems.
Technical Context
The 7024L20PFGI8 implements full hardware port arbitration with dedicated BUSY flag signaling (M/S = H for master output, M/S = L for slave input) and non-tri-stated push-pull interrupt outputs. Its dual-port architecture permits concurrent read/write operations across independent address/data/control buses without external logic.
It integrates full on-chip semaphore logic accessible via A0–A2 addressing and I/O0 write, supporting eight shared flags for inter-processor synchronization. The device operates fully asynchronously per port and enters ultra-low-power standby (1 µA typical) when both chip enables are deasserted with CMOS-level inputs.
Key Specifications

Pinout & Package
7024L20PFGI8 is housed in a 100-pin TQFP (PNG100) package with 0.5 mm pitch, requiring standard reflow profiles. Pin functions are electrically isolated between left and right ports, with dedicated control signals per side (CEL/CER, R/WL/R/WR, OEL/OER, UBL/UBR, LBL/LBR, SEML/SEMR, INTL/INTR, BUSYL/BUSYR).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A11L / A0R–A11R | Address Inputs (Left/Right) | 12-bit independent address buses enabling concurrent access to any of 4K locations per port |
| I/O0L–I/O15L / I/O0R–I/O15R | Bidirectional Data (Left/Right) | 16-bit parallel data paths; upper/lower byte control (UBL/UBR, LBL/LBR) supports multiplexed bus interfacing |
| CEL / CER | Chip Enable (Left/Right) | Active-low enables per port; allows independent power-down of either port to reduce system standby current |
| R/WL / R/WR | Read/Write Control (Left/Right) | Direct TTL-compatible control of memory operation direction without external decode logic |
| OEL / OER | Output Enable (Left/Right) | Tri-state control of data outputs; enables bus sharing with other peripherals on common data lines |
| SEML / SEMR | Semaphore Enable (Left/Right) | Activates on-chip 3-bit addressable semaphore register (A0–A2) for inter-processor lock management |
| BUSYL / BUSYR | Busy Flag (Left/Right) | Push-pull output (master) or input (slave); resolves port contention during simultaneous access to same address |
| M/S | Master/Slave Select | Configures device role in cascaded systems: HIGH = BUSY output (master), LOW = BUSY input (slave) |
| INTL / INTR | Interrupt Flag (Left/Right) | Open-drain capable (per datasheet note 2), signals semaphore state change or arbitration event to host processor |
Key Features
| Feature | Design Value |
|---|---|
| True Dual-Port Architecture | Enables simultaneous read of identical memory location by both ports-critical for real-time data mirroring and co-processor handshaking |
| On-Chip Semaphore Logic | Eight hardware semaphore flags addressed via A0–A2, eliminating need for external locking circuitry in multi-CPU systems |
| Automatic Power-Down | Chip enable–controlled entry into 0.2 mA standby mode preserves battery life in always-on industrial monitoring nodes |
| Full Hardware Arbitration | Dedicated BUSY flag generation and priority resolution (tAPS = 5 ns) prevents data corruption during port contention |
| Industrial Temperature Range | Validated operation from –40°C to +85°C ensures reliability in factory automation, transportation, and energy infrastructure environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C136-20VC | 4K × 16, 20 ns, 5V, 84-pin PLCC; no integrated semaphore logic; higher active current (1.2 A vs. 170 mA typ.) | Lacks hardware semaphore support-requires external logic for multi-CPU sync; unsuitable for space-constrained designs needing arbitration offload | Select only if semaphore functionality is implemented in FPGA or MCU firmware and PLCC packaging is mandated. |
| AS7C34096A-20TIN | 4K × 16, 20 ns, 3.3V core (5V tolerant I/O), 100-pin TQFP; lower power (ISB = 5 µA), but no BUSY/INT arbitration signals | No native port contention resolution-relies on software polling or external arbiter; incompatible with legacy 5V-only systems | Prefer for new 3.3V designs where power efficiency outweighs need for hardware arbitration and 5V compatibility. |
Compared with CY7C136-20VC and AS7C34096A-20TIN, the 7024L20PFGI8 uniquely delivers integrated semaphore arbitration, 5V TTL compatibility, and industrial temperature support in a single 100-pin TQFP package-enabling simpler, more reliable dual-processor memory sharing without external glue logic.

FAQ
What is the maximum operating temperature range for the 7024L20PFGI8?
The 7024L20PFGI8 is rated for industrial temperature operation from –40°C to +85°C. This specification is validated across all electrical parameters including access time (20 ns max), data retention (2 V), and standby current (0.2 mA typical). It does not support military or commercial grade temperature ranges.
Does the 7024L20PFGI8 support battery backup operation?
Yes, the 7024L20PFGI8 supports battery backup with guaranteed data retention at VCC = 2.0 V. In this mode, it draws ≤4000 µA (typical 100 µA) over the industrial temperature range, enabling long-term storage of critical configuration or fault data during main power loss without external circuitry.
How does the BUSY flag function in master/slave configuration for the 7024L20PFGI8?
When M/S = HIGH, the 7024L20PFGI8 operates as master: BUSYL/BUSYR are push-pull outputs asserting during port contention. When M/S = LOW, it operates as slave: BUSYL/BUSYR become inputs accepting BUSY signals from a master device. This enables hierarchical arbitration in multi-device systems without external logic.
What package type is used for the 7024L20PFGI8?
The 7024L20PFGI8 uses a 100-pin Thin Quad Flatpack (TQFP) package, designated PNG100, with 14 mm × 14 mm body size and 0.5 mm lead pitch. This RoHS-compliant package supports automated SMT assembly and provides thermal performance suitable for industrial ambient conditions.
Can the 7024L20PFGI8 perform simultaneous read operations on both ports to the same memory address?
Yes, the 7024L20PFGI8 features true dual-port memory cells that allow simultaneous reads from the same address location on left and right ports with no timing penalty or BUSY assertion. This capability is fundamental to its architecture and is explicitly confirmed in the datasheet's "Features" section.
