Renesas 7014S12PFG8

Overview

7014S12PFG8 from Renesas Electronics is a high-speed 4K × 9 true dual-port static RAM with independent asynchronous ports, 12 ns maximum read/write cycle time (commercial grade), TTL-compatible 5 V ±10% operation, and 750 mW typical active power dissipation - used in real-time inter-processor communication and video frame buffering where simultaneous port access without BUSY arbitration is required.

For engineers reviewing the 7014S12PFG8 datasheet, 7014S12PFG8 pinout, 7014S12PFG8 application, or 7014S12PFG8 equivalent, key selection criteria include dual-port timing symmetry, 9-bit data width supporting parity, TQFP-64 package compatibility, and absence of on-chip arbitration logic requiring external conflict resolution.

Technical Context

The 7014S12PFG8 implements fully asynchronous dual-port architecture with separate address, control, and I/O pins per port - enabling concurrent read operations to the same memory location. It lacks chip enable and operates continuously after power-up, with each port using dedicated OE and R/W controls.

Its 9-bit data path supports user-configurable parity handling for error detection in serial/data link applications. Timing parameters including tAA (12 ns), tRC (12 ns), and tWC (12 ns) are guaranteed only for commercial temperature range (0°C to +70°C) and apply identically to both left and right ports.

Key Specifications

Pinout & Package

7014S12PFG8 is packaged in a 64-pin thin quad flatpack (TQFP), body size 14 mm × 14 mm × 1.4 mm, with lead-free (green) finish and tape-and-reel delivery (suffix '8'). All GND and VCC pins require proper decoupling per layout guidelines.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-port SRAM applications.

Compared with CY7C1362BV33-12BGXI and IDT70V27L12PF8, the 7014S12PFG8 uniquely combines 5 V operation, TQFP-64 packaging, and commercial-grade 12 ns timing - making it the sole viable option for new 5 V dual-processor designs requiring compact surface-mount integration without voltage translation.

Manufacturer

Renesas Electronics Corporation is a Japanese semiconductor manufacturer specializing in microcontrollers, analog, power, and memory solutions for automotive, industrial, and infrastructure markets.

The 7014S series was designed as high-speed dual-port SRAMs for deterministic, arbitration-free data exchange between asynchronous processing units - targeting communications, imaging, and control systems where timing predictability is critical.

FAQ

What is the operating temperature range supported by the 7014S12PFG8?

The 7014S12PFG8 is rated for commercial temperature operation only: 0°C to +70°C. It does not support industrial temperature range (–40°C to +85°C); that capability was discontinued for the 12 ns speed grade per Renesas PDN# SP-17-02. This limitation must be accounted for in thermal design and environmental qualification testing for the 7014S12PFG8.

Does the 7014S12PFG8 include on-chip arbitration logic for simultaneous write conflicts?

No, the 7014S12PFG8 has no internal arbitration circuitry. When both ports attempt to write to the same memory location simultaneously, partial data from either port may be latched unpredictably. System-level arbitration - such as external priority encoders or handshake protocols - must be implemented to ensure data integrity. This design choice reduces latency but increases system design complexity for the 7014S12PFG8.

Can the 7014S12PFG8 operate with a 3.3 V supply?

No, the 7014S12PFG8 requires a 5.0 V ±10% supply (4.5 V to 5.5 V) and is TTL-compatible. It is not specified for 3.3 V operation, and applying 3.3 V will result in undefined behavior, including failure to meet timing specifications and potential data corruption. For 3.3 V dual-port SRAM, alternative parts like CY7C1362BV33-12BGXI must be evaluated instead of the 7014S12PFG8.

What package type and lead finish does the 7014S12PFG8 use?

7014S12PFG8 uses a 64-pin thin quad flatpack (TQFP) with body dimensions 14 mm × 14 mm × 1.4 mm and green (lead-free) RoHS-compliant finish. The 'PF' in the part number denotes TQFP, 'G' indicates green finish, and '8' specifies tape-and-reel packaging - confirmed in Renesas ordering information tables and pin configuration diagrams for the 7014S12PFG8.

Is the 7014S12PFG8 still in active production or subject to discontinuation?

The 7014S12PFG8 was covered under Renesas Product Discontinuation Notice PDN# SP-17-02, with last-time-buy expiring June 15, 2018. While Aetrix Electronics maintains legacy inventory and supply chain continuity support, the 7014S12PFG8 is no longer manufactured. Customers should plan for long-term obsolescence mitigation, including redesign evaluation or secured stockpiling of the 7014S12PFG8.
