Renesas Electronics 7134LA70P SRAM Equivalent & Substitute Parts

Part Overview

The Renesas Electronics 7134LA70P is a 32Kbit dual-port asynchronous SRAM with parallel interface, housed in a 48-DIP package. This component is classified as obsolete, making equivalent substitutes necessary for ongoing system support and new designs. The part operates within a 4.5V to 5.5V supply range with a 70 ns access time and write cycle time, suitable for legacy memory applications requiring volatile storage with parallel data access.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7134LA70P is determined by the following critical parameters:

• Memory capacity (32Kbit) and organization (4K x 8)
• Dual-port asynchronous SRAM technology
• Parallel interface configuration
• 48-DIP through-hole package footprint
• Supply voltage compatibility (4.5V ~ 5.5V)

The 7134LA35CB qualifies as a direct substitute based on matching memory size, organization, technology, interface type, and package form factor. Performance characteristics such as access time and operating temperature range may differ, but the part maintains functional equivalence for applications where the original 7134LA70P is specified.

Parameter Comparison

Engineering Selection Recommendations

The 7134LA35CB is the manufacturer-recommended substitute for the obsolete 7134LA70P. Both parts are manufactured by Renesas Electronics Corporation and maintain identical memory capacity, organization, and interface specifications. The 7134LA35CB offers improved performance with 35 ns access and write cycle times compared to the 70 ns specification of the original part, and operates across an extended temperature range of -55°C to 125°C versus the original 0°C to 70°C range.

The 7134LA35CB is currently in active production status, ensuring availability for new designs and system replacements. Both parts carry RoHS non-compliant and REACH unaffected designations. The physical package footprint remains identical, enabling direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the 7134LA35CB directly replace the 7134LA70P in existing designs?

A: Yes. Both parts share identical memory capacity (32Kbit), organization (4K x 8), dual-port asynchronous architecture, parallel interface, supply voltage range (4.5V ~ 5.5V), and 48-DIP through-hole package dimensions. The 7134LA35CB provides faster access times and broader temperature operation, making it functionally compatible for direct substitution.

Q: What are the key differences between these parts?

A: The primary differences are access time (70 ns versus 35 ns), write cycle time (70 ns versus 35 ns), and operating temperature range (0°C ~ 70°C versus -55°C ~ 125°C). The 7134LA35CB also features active product status compared to the obsolete status of the 7134LA70P.

Q: Are there package compatibility concerns?

A: No. Both parts use the 48-DIP package with identical 0.600" (15.24mm) dimensions and through-hole mounting configuration. No PCB layout or socket modifications are required.

Q: Does the 7134LA35CB meet the same compliance standards?

A: Both parts share identical RoHS non-compliant and REACH unaffected designations. Compliance status remains consistent between the original and substitute part.

Q: Why is the 7134LA70P classified as obsolete?

A: The 7134LA70P has reached end-of-life status with Renesas Electronics Corporation. The 7134LA35CB represents the active production equivalent, ensuring continued availability and support for applications requiring 32Kbit dual-port SRAM with parallel interface in 48-DIP packaging.
