Product details
Overview
7024L20PF8 from IDT is a high-speed 4K × 16 true dual-port static RAM with independent left/right ports, 20 ns max read cycle time (commercial/industrial), 1 mW typical standby power, and full on-chip semaphore arbitration logic-used in real-time inter-processor communication systems requiring simultaneous, conflict-free memory access.
For engineers reviewing the 7024L20PF8 datasheet, 7024L20PF8 pinout, 7024L20PF8 application, or 7024L20PF8 equivalent, this page delivers verified timing specs, master/slave BUSY flag behavior, battery-backed data retention at 2V, TTL-compatible 5V operation, and precise TQFP-100 pin mapping for deterministic dual-port memory integration.
Technical Context
The 7024L20PF8 implements fully asynchronous dual-port architecture with separate address, control, and I/O buses per port, enabling concurrent reads/writes to the same location without corruption. Its on-chip arbitration logic resolves port contention via BUSY flag signaling and supports semaphore flag management across eight shared flags addressed by A0–A2.
It operates in MASTER mode (M/S = H) with BUSY output or SLAVE mode (M/S = L) with BUSY input, enabling scalable cascading for 32-bit+ bus width expansion. The device supports battery backup with 2V data retention and enters ultra-low-power standby (<1 mW typ.) when both chip enables are deasserted.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Memory Organization | 4K × 16 (64 Kbit), true dual-port SRAM with independent left/right access paths |
| Max Read Cycle Time | 20 ns - guarantees ≤20 ns latency for full-word reads under commercial/industrial conditions |
| Standby Current | 1 mW typical (IDT7024L) - enables battery-backed operation with minimal quiescent drain |
| Data Retention Voltage | 2.0 V minimum - retains valid data during main power loss using external backup supply |
| Supply Voltage | 5.0 V ±10% - TTL-compatible single-supply operation, no level-shifting required |

Pinout & Package
7024L20PF8 is housed in a 100-pin Thin Quad Flatpack (TQFP) package with 0.5 mm pitch, 14 mm × 14 mm body size, and exposed thermal pad (per IDT PNG100 specification). All VCC and GND pins must be individually decoupled per datasheet layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A11L | Left-port address inputs | 12-bit address bus for left-side memory access; supports full 4K addressing |
| A0R–A11R | Right-port address inputs | Independent 12-bit address bus for right-side access; enables true concurrency |
| I/O0L–I/O15L | Left-port bidirectional data | 16-bit data path; upper/lower byte controlled separately via UBL/LBL |
| I/O0R–I/O15R | Right-port bidirectional data | 16-bit data path; fully isolated from left port except via shared memory array |
| CEL / CER | Chip enable (left/right) | Active-low enables; controls port activation and power-down entry independently |
| R/WL / R/WR | Read/write control (left/right) | Active-low write enable; determines direction of data flow per port |
| OEL / OER | Output enable (left/right) | Active-low enables outputs; allows high-impedance tri-state for bus sharing |
| UBL / UBR | Upper-byte select | Enables I/O8–I/O15 only; supports multiplexed 8-bit bus compatibility |
| LBL / LBR | Lower-byte select | Enables I/O0–I/O7 only; enables byte-level granularity for mixed-width systems |
| SEML / SEMR | Semaphore enable | Activates 3-bit semaphore address decoding (A0–A2) for inter-port synchronization |
| BUSYL / BUSYR | Busy flag (left/right) | In MASTER mode: BUSY is output; in SLAVE mode: BUSY is input for arbitration |
| INTL / INTR | Interrupt flag | Open-drain push-pull output signals semaphore or arbitration events to host processor |
| M/S | Master/Slave select | Configures device role: HIGH = BUSY output (master); LOW = BUSY input (slave) |
Key Features
| Feature | Design Value |
|---|---|

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-20AXC | 20 ns access, 4K × 16, 3.3V core with 5V-tolerant I/O; lower active power (350 mW typ.) but no 2V data retention | Requires level translation in 5V-only systems; unsuitable for battery-backup designs | Select when migrating to lower-voltage infrastructure and external backup is acceptable |
| IS61LV25616AL-20TQLI | 20 ns, 16K × 16, 3.3V only, no dual-port arbitration logic or BUSY/SEM pins | Lacks hardware semaphore and port arbitration-requires external logic or software coordination | Choose only for simple shared-memory use cases where arbitration is handled externally |
Compared with CY7C024AV-20AXC and IS61LV25616AL-20TQLI, the 7024L20PF8 uniquely integrates master/slave BUSY signaling, on-chip semaphores, and 2V data retention-making it irreplaceable in legacy 5V industrial and aerospace systems demanding hardware-enforced concurrency control.

FAQ
What is the maximum operating speed of the 7024L20PF8?
The 7024L20PF8 has a maximum read cycle time of 20 ns, corresponding to a theoretical maximum throughput of 50 MHz for consecutive reads. This rating applies across commercial (0°C to +70°C) and industrial (–40°C to +85°C) temperature ranges, with full functionality maintained at VCC = 5.0 V ±10%.
Does the 7024L20PF8 support battery backup operation?
Yes, the 7024L20PF8 (L-version) supports battery backup with guaranteed data retention at VCC = 2.0 V minimum. In data retention mode, ICCDR is typically 100 µA and up to 4000 µA across military/industrial grades-enabling long-term storage during main power loss without external refresh circuitry.
How does the M/S pin configure master/slave operation in the 7024L20PF8?
When M/S = HIGH, the 7024L20PF8 operates as a MASTER: BUSYR and BUSYL become output signals indicating port contention. When M/S = LOW, it operates as a SLAVE: BUSYR and BUSYL become inputs, allowing external master devices to control arbitration-enabling seamless cascading for 32-bit+ word systems.
What is the function of the semaphore logic in the 7024L20PF8?
The 7024L20PF8 includes eight hardware semaphore flags accessible via I/O0–I/O15 and addressed by A0–A2. When SEM = LOW, writes to I/O0 set flags; reads return flag states across all 16 I/O lines. This eliminates software locks and external arbitration logic for inter-processor synchronization.
Which package type does the 7024L20PF8 use, and what are its key mechanical features?
The 7024L20PF8 uses a 100-pin Thin Quad Flatpack (TQFP) per IDT's PNG100 specification: 14 mm × 14 mm body, 0.5 mm lead pitch, and RoHS-compliant finish. It includes dedicated VCC and GND pins distributed across all four sides for optimal power integrity and EMI performance in high-speed designs.
