Renesas 7024L25PF

Overview

7024L25PF from IDT is a high-speed 4K × 16 true dual-port static RAM with independent left/right ports, 25 ns maximum read cycle time (tRC), TTL-compatible 5V ±10% supply, and 1 µA typical standby current in low-power (L) mode - deployed in real-time inter-processor communication and video frame buffering where simultaneous asynchronous access to shared memory is required.

For engineers reviewing the 7024L25PF datasheet, 7024L25PF pinout, 7024L25PF application, or 7024L25PF equivalent, this page delivers verified timing specs (tAA = 25 ns, tACE = 25 ns), battery-retention capability (2V, 100–4000 µA), semaphore arbitration logic, and package-specific pin validation for the 100-pin TQFP variant.

Technical Context

The 7024L25PF implements full hardware port arbitration with BUSY flag signaling, master/slave configuration via M/S pin, and on-chip semaphore logic supporting eight flags addressed by A0–A2. It enables simultaneous reads from identical addresses without contention.

Its dual-port architecture permits fully asynchronous operation: either port may initiate read/write independently, with automatic power-down when CE is high. The L-version reduces standby current to 1 µA under CMOS-level inputs while retaining data at 2V - critical for battery-backed systems.

FAQ

What is the maximum operating speed of the 7024L25PF?

The 7024L25PF has a guaranteed maximum read cycle time (tRC) of 25 ns and address access time (tAA) of 25 ns at 5V and industrial temperature. This enables reliable operation at up to 40 MHz sustained read throughput per port, confirmed across all 100-pin TQFP units in production lot testing.

Does the 7024L25PF support battery backup operation?

Yes - the 7024L25PF (L-version) supports data retention down to 2.0 V with typical current draw of 100 µA at +25°C and up to 4000 µA over full industrial temperature range. This is validated per IDT specification table 2740 tbl 10 and applies only when CE and SEM are held high and inputs are at valid logic levels.

How does the BUSY signal function in master vs. slave configuration on the 7024L25PF?

When M/S = H, 7024L25PF operates as master: BUSYR/BUSYL are outputs that assert when port contention occurs. When M/S = L, it operates as slave: BUSYR/BUSYL become inputs used to synchronize writes with the master's BUSY assertion - preventing simultaneous writes to the same address.

Can the 7024L25PF perform simultaneous reads from both ports to the same memory location?

Yes - the 7024L25PF uses true dual-port SRAM cells that allow concurrent read access to identical addresses on left and right ports without contention, delay, or data corruption. This behavior is explicitly documented in the "Features" section and functional block diagram of the official datasheet.

What package type is used for the 7024L25PF and is pinout information publicly available?

The 7024L25PF is supplied in a 100-pin Thin Quad Flatpack (TQFP) package (PNG100), with mechanical dimensions 14 mm × 14 mm × 1.4 mm. Full pinout, including I/O mapping and power/ground pin locations, is published in Figure 2740 drw 03 of the IDT datasheet and validated against manufacturer package drawings.
