Product details
Overview
7024L35PF from IDT is a high-speed 4K × 16 true dual-port static RAM with independent left/right ports, 35 ns max read cycle time (tRC), 2V data retention capability, and full on-chip semaphore arbitration logic-designed for real-time inter-processor communication in military-grade embedded systems requiring simultaneous asynchronous access to shared memory.
For engineers reviewing the 7024L35PF datasheet, 7024L35PF pinout, 7024L35PF application, or 7024L35PF equivalent, this page delivers verified specifications, validated pin functions, confirmed industrial/military temperature support (–40°C to +85°C), exact package mapping (100-pin TQFP), and two technically documented alternative parts for dual-port SRAM replacement scenarios.
Technical Context
The 7024L35PF implements fully asynchronous dual-port architecture with separate address, control, and I/O buses per port, enabling concurrent read/write operations-even to the same memory location-without external arbitration logic. Its on-chip port arbitration resolves contention via BUSY flag signaling and M/S master/slave configuration.
It supports semaphore flag management across both ports using A0–A2 addressing and I/O0 for write, with dedicated SEM, INT, and BUSY signals. The device operates at 5.0 V ±10% with TTL-compatible inputs and provides battery backup data retention down to 2 V, with low-power standby current of 1 µA (typ.) in full CMOS-level disable mode.
