Product details
Overview
7014S15PF from Renesas Electronics is a high-speed 4K × 9 true dual-port static RAM with independent asynchronous ports, 15 ns maximum read access time (tAA), TTL-compatible 5 V ±10% operation, and 750 mW typical active power consumption. It enables simultaneous reads from both ports to the same memory location and supports parity-enabled data communication systems.
For engineers reviewing the 7014S15PF datasheet, 7014S15PF pinout, 7014S15PF application, or 7014S15PF equivalent, this device serves as a low-latency, fully asynchronous dual-access memory for real-time inter-processor communication, video frame buffering, and telecom packet buffering where hardware arbitration is handled externally.
Technical Context
The 7014S15PF implements two fully independent address/data/control paths - left port (A0L–A11L, I/O0L–I/O8L) and right port (A0R–A11R, I/O0R–I/O8R) - with no internal bus arbitration logic. Each port features dedicated R/W, OE, and address inputs, enabling concurrent read/write operations without BUSY signal dependency.
It uses standard-power CMOS technology with TTL-level input thresholds (VIH = 2.2 V min, VIL = 0.8 V max) and drives outputs to VOH ≥ 2.4 V at –4 mA and VOL ≤ 0.4 V at +4 mA. The device operates only on a single 5 V supply and requires all VCC and GND pins to be connected per package layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 4K × 9 bits (36 Kbit total); supports 9-bit wide data path for optional parity bit handling in serial/parallel comms |
| Access Time (tAA) | 15 ns max (commercial grade, 0°C to +70°C); defines minimum delay from address valid to stable output data |
| Read Cycle Time (tRC) | 15 ns max; determines shortest interval between successive read operations on same port |
| Supply Voltage | 4.5 V to 5.5 V; single-rail TTL-compatible operation eliminates need for voltage translation in legacy 5 V systems |
| Active Power (ICC) | 160 mA typ (250 mA max) with both ports active; translates to ~750 mW typical at 5 V, suitable for thermally constrained modules |
| I/O Capacitance | CIN = 9 pF, COUT = 10 pF (TQFP package); ensures predictable timing margins under 30 pF AC test load per JEDEC standards |
| Output Enable Access (tAOE) | 8 ns max; specifies latency from OE assertion to valid data, critical for burst-mode peripheral interfacing |
Pinout & Package
7014S15PF is packaged in a 64-pin thin quad flatpack (TQFP, package code PNG64), measuring 14 mm × 14 mm × 1.4 mm. All 64 pins are electrically assigned; N/C pins are unused and must remain unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A11L | Left port address inputs | 12-bit address bus for left-side memory access; fully asynchronous from right port |
| A0R–A11R | Right port address inputs | 12-bit address bus for right-side memory access; no timing dependency on left port |
| I/O0L–I/O8L | Left port bidirectional data | 9-bit data path supporting parity; high-impedance when OE_L = HIGH or R/W_L = LOW during write |
| I/O0R–I/O8R | Right port bidirectional data | 9-bit data path mirroring left port; enables full-duplex memory sharing between two controllers |
| R/WL / R/WR | Left/right write enable | Active-HIGH control: HIGH = read, LOW = write; no chip-enable - device powers up active |
| OEL / OER | Left/right output enable | Active-LOW control: LOW enables outputs; HIGH forces I/O pins to high-impedance state |
| VCC (Pins 17, 32, 49, 64) | Power supply | Four dedicated 5 V supply pins reduce IR drop and improve noise immunity across high-speed switching |
| GND (Pins 1, 16, 33, 50) | Ground reference | Four ground pins provide low-inductance return paths essential for signal integrity at 15 ns timing |
Key Features
| Feature | Design Value |
|---|---|
| True dual-port architecture | Enables simultaneous independent read accesses to identical memory locations - eliminates arbitration overhead in FPGA-to-ASIC handshaking |
| 15 ns read access (tAA) | Supports 66.7 MHz sustained read throughput per port, meeting timing budgets in legacy PCI/ISA-based real-time controllers |
| 9-bit data width with parity option | Allows user-configurable 8+1 bit framing for error detection in synchronous serial links (e.g., HDLC, T1/E1 interfaces) |
| No internal chip enable | Device remains fully operational immediately after power-up - simplifies power sequencing in multi-rail systems |
| TTL-compatible interface | Direct connection to 5 V microcontrollers, FPGAs, and ASICs without level shifters; VIH/VIL thresholds match legacy logic families |
Applications
| Telecom Packet Buffering | Real-Time Inter-Processor Communication |
|---|---|
|
Use Scenario: Storing and forwarding ATM or Ethernet frames between ingress and egress line cards in legacy telecom switches. IC Role / Device Role / Timing Role: Dual-port RAM acts as a zero-wait-state shared memory buffer, allowing one port to write incoming packets while the other reads outgoing packets. Use Value: 15 ns tAA and 8 ns tAOE enable sub-20 ns turnaround latency, sustaining >50 Mpps packet processing without external arbitration logic. |
Use Scenario: Coordinating sensor fusion data between a DSP and an ARM host processor in industrial motion control systems. IC Role / Device Role / Timing Role: Serves as a lock-free shared memory region where DSP writes processed motor feedback and ARM reads actuator commands. Use Value: Simultaneous read capability allows both processors to monitor status flags and data buffers concurrently, eliminating polling delays. |
| Video Frame Synchronization | Legacy Bus Bridge Buffering |
|
Use Scenario: Aligning asynchronous video streams from multiple cameras in broadcast-grade capture hardware. IC Role / Device Role / Timing Role: Buffers full NTSC/PAL frames (720 × 480 × 2 bytes) across two independent pixel clocks using separate ports. Use Value: 4K × 9 organization provides 36 Kbits - sufficient for dual-line buffering with embedded sync words and CRC fields. |
Use Scenario: Bridging ISA and VME buses in test equipment requiring deterministic memory access from both domains. IC Role / Device Role / Timing Role: Acts as a transparent, non-blocking memory window accessible by ISA master and VME slave simultaneously. Use Value: Fully asynchronous operation avoids clock domain crossing circuits; 5 V tolerance matches both bus voltage standards. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C1362V-15ZXI | 4K × 16 organization, 15 ns speed, 3.3 V core (with 5 V tolerant I/O), integrated busy arbitration logic | Requires external level translation for pure 5 V systems; built-in BUSY simplifies priority resolution but adds latency | Select when system needs automatic conflict resolution and can accommodate 3.3 V supply; not drop-in for 5 V-only designs |
| IDT70V27L15PF | 4K × 9, 15 ns, 3.3 V operation, LVCMOS interface, lower ICC (90 mA typ), same TQFP-64 footprint | Not electrically compatible with 5 V TTL; requires redesign of surrounding logic and power delivery | Choose for new low-power designs targeting 3.3 V ecosystems; pinout matches but voltage domain differs |
Compared with CY7C1362V-15ZXI and IDT70V27L15PF, the 7014S15PF uniquely delivers true 5 V TTL compatibility, no-BUSY operation, and proven integration in legacy industrial telecom platforms - making it irreplaceable where backward electrical and timing compatibility is mandatory.

FAQ
What is the operating temperature range for the 7014S15PF?
The 7014S15PF is rated for commercial temperature operation only: 0°C to +70°C. It does not support industrial or extended temperature grades. This is explicitly defined in the Ordering Information section and confirmed by AC/DC characterization tables limited to commercial conditions. The 7014S15PF datasheet contains no industrial-grade timing or electrical specifications.
Does the 7014S15PF include on-chip arbitration logic?
No, the 7014S15PF has no internal arbitration circuitry. Its functional description states clearly that "there is no on-chip arbitration circuitry to resolve write priority." When both ports attempt to write to the same address simultaneously, partial data from either port may be latched - users must implement external arbitration or avoid concurrent writes to identical locations.
What package type is used for the 7014S15PF?
The 7014S15PF uses a 64-pin thin quad flatpack (TQFP) with package code PNG64. This is confirmed in the Ordering Information table, Pin Configuration diagrams, and package dimension notes specifying 14 mm × 14 mm × 1.4 mm body size. The PLCC variant (PLG52) carries different orderable part numbers (e.g., 7014S15JG).
Can the 7014S15PF operate with a 3.3 V supply?
No, the 7014S15PF requires a 5 V ±10% supply (4.5 V to 5.5 V). Its DC operating conditions, VIH/VIL thresholds, and power consumption data are all specified exclusively for 5 V operation. Attempting 3.3 V operation will result in undefined behavior, failed reads/writes, and potential output contention due to insufficient drive strength.
Is the 7014S15PF still in active production?
The 7014S15PF was discontinued per Renesas Product Discontinuation Notice PDN# SP-17-02, with last-time-buy expiring June 15, 2018. However, Aetrix Electronics maintains verified legacy stock with full traceability and supports ongoing production programs through lifecycle availability coordination and obsolescence mitigation services.
