Product details
Overview
CY7C024-15JXC from Cypress Semiconductor is a 4K × 16-bit true dual-port static RAM with independent asynchronous left/right ports, 15 ns access time, on-chip semaphore logic, and BUSY/INT flags-designed for interprocessor communication in real-time embedded control systems.
For engineers reviewing the CY7C024-15JXC datasheet, CY7C024-15JXC pinout, CY7C024-15JXC application, or CY7C024-15JXC equivalent, key selection criteria include dual-port arbitration timing (tPS = 10 ns), M/S-configurable master/slave expansion, and semaphore-controlled resource sharing across heterogeneous processors.
Technical Context
The CY7C024-15JXC implements fully asynchronous dual-port operation with separate CE/R/W/OE controls per port, enabling concurrent read/write to distinct addresses without arbitration delay. Its on-chip arbitration resolves contention via BUSY assertion within tBLA = 8 ns after address match.
Semaphore logic comprises eight dedicated latches accessible via SEM pin activation and A0–A2 addressing; each latch enforces exclusive ownership by driving I/O0 low on acquisition and propagating state to the opposite port. INT flags use upper memory locations (FFE/FFF) as mailbox registers for deterministic port-to-port messaging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 4K × 16-bit (65,536 bits total), two independent address/data paths |
| Access Time | 15 ns maximum-guarantees deterministic data availability for 66 MHz bus interfaces |
| Supply Voltage | 5 V ±10%-compatible with legacy TTL/CMOS logic families without level translation |
| Operating Current | 190 mA typical at 15 ns-enables thermal management in dense multi-processor PCB layouts |
| Arbitration Timing | tPS = 10 ns setup window-defines minimum address skew between ports to ensure predictable BUSY resolution |
| Semaphore Latency | tSOP = 10 ns minimum OE/SEM deassertion before read-ensures stable latch state sampling |
| Interrupt Mailbox | Addresses FFE (left) and FFF (right)-provides hardware-synchronized message passing without polling overhead |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IDT70V25L15PF | 4K × 16-bit, 15 ns, 3.3 V supply-requires level shifters for 5 V systems | Lacks integrated semaphores; requires external logic for resource arbitration | Choose when migrating to lower-voltage platforms and external arbitration is acceptable |
| CY7C028-15JC | 8K × 16-bit, same 15 ns speed and 5 V supply-pin-compatible but larger memory depth | Higher address count (A0–A12 vs A0–A11) requires PCB redesign for unused pins | Choose when application requires >4K words and board layout allows A12 routing |
Compared with IDT70V25L15PF and CY7C028-15JC, the CY7C024-15JXC uniquely integrates semaphores and 5 V compatibility in a 4K × 16 footprint-making it optimal for legacy industrial controllers needing drop-in arbitration support without voltage conversion or memory over-provisioning.

FAQ
What is the function of the M/S pin on CY7C024-15JXC?
The M/S pin configures the device as master (M/S = HIGH) or slave (M/S = LOW). In master mode, BUSY pins act as outputs signaling arbitration results; in slave mode, BUSY pins become inputs accepting arbitration signals from a master device. This enables seamless 32-bit memory expansion using identical CY7C024-15JXC units without external glue logic.
How do the semaphore latches operate in CY7C024-15JXC?
The eight semaphore latches are accessed via SEM pin assertion and A0–A2 addressing. Writing '0' to a semaphore grants exclusive ownership-reflected as '0' on the writing port and '1' on the opposite port. Only the owning port can modify the latch; writing '1' releases ownership, allowing the other port to acquire it immediately if pending. All operations require tSOP = 10 ns OE/SEM deassertion before read.
Can CY7C024-15JXC support simultaneous read and write to the same memory location?
No-simultaneous access to the same address triggers on-chip arbitration. The BUSY flag asserts on the losing port within 8 ns (tBLA), blocking its access until the winning port completes the cycle. Deterministic resolution requires address setup skew ≤10 ns (tPS); violation makes winner unpredictable. True simultaneous access is only permitted to distinct addresses.
What are the valid operating temperature ranges for CY7C024-15JXC?
CY7C024-15JXC is rated for commercial (0°C to +70°C) and industrial (–40°C to +85°C) ambient temperatures. The JXC suffix denotes the industrial-grade version with extended temperature range and Pb-free 84-pin PLCC packaging. Electrical specifications-including 15 ns access time and 190 mA typical ICC-are guaranteed across the full –40°C to +85°C range.
