Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7014S12PF is determined by strict equivalence across the following critical parameters:

• Memory capacity and organization (36Kbit, 4K x 9 configuration)
• Access and write cycle timing (12 ns)
• Dual-port asynchronous architecture
• Parallel interface specification
• Supply voltage compatibility (4.5V ~ 5.5V)
• Package form factor (64-TQFP)
• Operating temperature range (0°C ~ 70°C)

The substitute part 7014S12PFG maintains identical electrical and mechanical specifications to the main part, with the primary distinction being product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The 7014S12PFG is the direct equivalent substitute for the 7014S12PF. Both parts are manufactured by Renesas Electronics Corporation and share identical electrical specifications and package dimensions. The 7014S12PFG is preferred for new designs and ongoing production due to its active product status and ROHS3 compliance. The main part remains available in inventory but is classified as obsolete.

For applications requiring the 36Kbit dual-port SRAM with 12 ns timing in a 64-TQFP package, the 7014S12PFG provides full functional and mechanical compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the 7014S12PFG directly replace the 7014S12PF in existing designs?

A: Yes. The 7014S12PFG is electrically and mechanically equivalent to the 7014S12PF. Both parts feature identical memory capacity (36Kbit), organization (4K x 9), access timing (12 ns), supply voltage range (4.5V ~ 5.5V), operating temperature range (0°C ~ 70°C), and 64-TQFP package form factor.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and compliance certification. The 7014S12PF is obsolete and RoHS non-compliant, while the 7014S12PFG is active and ROHS3 compliant. Packaging format differs (tube versus tray), but this does not affect electrical performance or board-level compatibility.

Q: Are there any timing or performance differences between these parts?

A: No. Both parts maintain identical access time (12 ns) and write cycle time (12 ns) specifications. Memory organization, interface type, and voltage supply requirements are identical.

Q: Is the 64-TQFP package pinout identical between both parts?

A: Yes. Both parts use the 64-TQFP (14x14) package with identical pinout and mechanical dimensions, ensuring direct PCB compatibility.

Q: Why should I select the 7014S12PFG over the 7014S12PF?

A: The 7014S12PFG is the recommended choice for new designs and production due to active product status and ROHS3 compliance. The 7014S12PF is obsolete and may face supply constraints.
