Product details
Overview
7014S12PF from Renesas Electronics is a high-speed 4K × 9 true dual-port static RAM with independent asynchronous ports, 12 ns maximum access time (commercial grade), TTL-compatible 5 V ±10% operation, and 750 mW typical active power consumption. It enables simultaneous read access to the same memory location from both ports and supports parity-enabled data communication systems.
For engineers reviewing the 7014S12PF datasheet, 7014S12PF pinout, 7014S12PF application, or 7014S12PF equivalent, this device serves as a low-latency, hardware-arbitration-free memory solution for real-time inter-processor communication, video frame buffering, and telecom packet buffering where deterministic timing and port independence are critical.
Technical Context
The 7014S12PF implements fully asynchronous dual-port architecture with separate address, control, and bidirectional I/O buses per port-no shared bus arbitration logic. Each port features independent R/W, OE, and address inputs, enabling concurrent read/write operations without BUSY signal dependency.
It uses standard-power CMOS process technology optimized for 5 V operation, delivering 12 ns tAA and tRC timing at commercial temperature range (0°C to +70°C). The 9-bit data width supports user-configurable parity bit handling, and all I/Os are TTL-compatible with VIH = 2.2 V min and VOL = 0.4 V max at IOL = +4 mA.
Key Specifications

| Package Type | 64-pin TQFP (PNG64), 14 mm × 14 mm × 1.4 mm - surface-mount compatible with automated PCB assembly |
Pinout & Package
7014S12PF is housed in a 64-pin thin quad flatpack (TQFP, package code PNG64), measuring 14 mm × 14 mm × 1.4 mm. All VCC pins require decoupling to GND; all GND pins must be connected to system ground. Pin 1 is marked with a dot; orientation follows standard counter-clockwise numbering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A11L | Left-port address inputs | 12-bit address bus for left-side memory access; independent of right-port addressing |
| A0R–A11R | Right-port address inputs | 12-bit address bus for right-side memory access; enables true parallel address decoding |
| I/O0L–I/O8L | Left-port bidirectional data I/O | 9-bit data path supporting parity; tri-stated when OEL = HIGH or R/WL = LOW during write |
| I/O0R–I/O8R | Right-port bidirectional data I/O | 9-bit data path mirroring left port; electrically isolated for simultaneous read/write |
| R/WL, R/WR | Left/right write-enable controls | Active-HIGH signals determining port direction; HIGH = read, LOW = write |
| OEL, OER | Left/right output enable controls | Active-LOW signals enabling I/O drivers; HIGH places port outputs in 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, 2, 33, 47) | Ground reference | Four ground pins provide low-inductance return paths for both ports' I/O and core logic |
Key Features
| Feature | Design Value |
|---|---|
| True dual-port memory cells | Enables simultaneous reads from identical addresses on both ports-no arbitration delay or BUSY overhead |
| 12 ns access time (commercial) | Supports real-time inter-processor handshaking at up to 83 MHz effective clock rate per port |
| 9-bit data width with parity option | Allows integration into serial/parallel data links requiring single-bit error detection without external logic |
| Fully asynchronous operation | Eliminates need for global clock synchronization between ports-ideal for heterogeneous processor interfacing |
| 52-pin PLCC and 64-pin TQFP options | 64-pin TQFP (7014S12PF) offers finer pitch, better thermal dissipation, and higher I/O density than PLCC variant |
Applications
| Telecom Packet Buffering | Real-Time Inter-Processor Communication |
|---|---|
|

Use Value: Asynchronous operation prevents pipeline stalls; TTL compatibility simplifies interface to legacy DSP address/data buses. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C136-12VXI | 4K × 8 organization, 12 ns speed, 3.3 V supply only; no 5 V tolerance | Lacks parity bit support; requires level-shifting in 5 V systems | Select only if migrating to 3.3 V architecture and 8-bit data path suffices |
| AS7C34098B-12TIN | 4K × 9, 12 ns, 3.3 V core with 5 V tolerant I/O; higher ICC (220 mA typ) | Compatible with mixed-voltage designs but consumes ~30% more dynamic power | Prefer when system uses 3.3 V supply but retains 5 V peripheral interfaces |
Compared with CY7C136-12VXI and AS7C34098B-12TIN, the 7014S12PF uniquely delivers native 5 V TTL operation with parity-enabled 9-bit width and minimal active power-making it optimal for legacy industrial and telecom systems where voltage compatibility and deterministic latency are non-negotiable.

FAQ
What is the operating temperature range for the 7014S12PF?
The 7014S12PF is specified for commercial temperature operation from 0°C to +70°C. It is not rated for industrial (-40°C to +85°C) or extended temperature ranges. This makes it suitable for controlled-environment applications such as office-based telecom gear or laboratory instrumentation where ambient thermal stability is assured. The 7014S12PF datasheet explicitly lists only commercial-grade speed bins (12 ns, 15 ns) and excludes industrial variants for this part number.
Does the 7014S12PF support simultaneous write operations to the same memory location?
No-the 7014S12PF lacks on-chip arbitration circuitry, so simultaneous writes to the same address from both ports may result in indeterminate or partial data corruption. The 7014S12PF functional description explicitly warns against this condition and recommends external arbitration or software coordination. Its design assumes coordinated access, not conflict resolution, making it unsuitable for unmanaged concurrent-write scenarios.
What package type does the 7014S12PF use, and how many pins does it have?
The 7014S12PF uses a 64-pin thin quad flatpack (TQFP) package, designated PNG64 in Renesas documentation. Its physical dimensions are 14 mm × 14 mm × 1.4 mm. This differs from the PLCC variant (PLG52), which has 52 pins. The "PF" suffix in 7014S12PF specifically denotes the TQFP packaging, confirmed in the Ordering Information table on page 9 of the datasheet.
Is the 7014S12PF still in active production, and what is its lifecycle status?
The 7014S12PF was discontinued per Renesas Product Discontinuation Notice PDN# SP-17-02, with last-time-buy expiring June 15, 2018. While Aetrix Electronics maintains limited legacy stock for design continuity, no new production runs exist. Customers should plan for obsolescence mitigation-such as migration to pin-compatible alternatives or redesign with newer dual-port architectures-when using the 7014S12PF in new programs.
How does the 9-bit data width of the 7014S12PF benefit system design?
The 9-bit data width of the 7014S12PF allows users to allocate one bit as a parity bit for error detection in data transmission or storage paths-without requiring external XOR gates or additional memory chips. In applications like serial communications or packetized data buffers, this capability reduces component count and improves reliability. The 7014S12PF's datasheet highlights this feature specifically for "data communication applications where it is necessary to use a parity bit for transmission/reception error checking."
