Renesas Electronics 7132SA55P SRAM Equivalent & Substitute Parts

Part Overview

The Renesas Electronics 7132SA55P is a 16Kbit dual-port asynchronous SRAM memory IC in 48-DIP packaging with 55 ns access time and parallel interface. This component is classified as obsolete, making substitute parts necessary for new designs and ongoing system support. The part operates within a 4.5V to 5.5V supply voltage range and supports industrial temperature applications from 0°C to 70°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7132SA55P is determined by the following critical parameters:

• Memory capacity and organization (16Kbit, 2K x 8 configuration)
• Dual-port asynchronous SRAM technology
• Parallel interface architecture
• 48-DIP through-hole package compatibility
• Supply voltage range (4.5V ~ 5.5V)
• Access time performance specifications

The Renesas Electronics 7132LA100CB qualifies as a functional substitute based on matching memory size, organization, technology, interface type, package form factor, and voltage specifications. The primary difference is extended access time (100 ns versus 55 ns) and broader operating temperature range (-55°C to 125°C versus 0°C to 70°C), with active product status enabling continued availability.

Parameter Comparison

Engineering Selection Recommendations

The 7132LA100CB is the designated manufacturer substitute for the obsolete 7132SA55P. Selection of this substitute is supported by:

• Identical memory capacity, organization, and dual-port asynchronous architecture
• Matching parallel interface and 48-DIP through-hole package
• Compatible supply voltage specifications (4.5V ~ 5.5V)
• Active product status ensuring continued availability and supply chain reliability
• Extended operating temperature range providing broader application flexibility

The 100 ns access and write cycle time of the 7132LA100CB represents a performance trade-off compared to the 55 ns specification of the original part. System designs must validate that this timing specification meets application requirements before implementation.

Frequently Asked Questions (FAQ)

Q: Can the 7132LA100CB directly replace the 7132SA55P in existing designs?

A: The 7132LA100CB provides functional substitution based on matching memory capacity, organization, interface type, and package form factor. The extended access time (100 ns versus 55 ns) must be evaluated against system timing requirements. Pin-compatible through-hole mounting supports direct board-level replacement.

Q: What is the primary difference between these two parts?

A: The main differences are access time performance (55 ns for 7132SA55P versus 100 ns for 7132LA100CB) and operating temperature range (0°C to 70°C versus -55°C to 125°C). The 7132LA100CB offers broader temperature coverage and active product status.

Q: Are there packaging differences between the main part and substitute?

A: Both parts use 48-DIP through-hole packaging with identical 0.600" (15.24mm) dimensions. The 7132SA55P is supplied in standard DIP packaging, while the 7132LA100CB is supplied in tube packaging. Both are compatible with standard through-hole assembly processes.

Q: What compliance certifications apply to both parts?

A: Both the 7132SA55P and 7132LA100CB are RoHS non-compliant and REACH unaffected. Both carry ECCN classifications and HTSUS commodity codes as specified for memory integrated circuits.

Q: Why is the 7132SA55P classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by Renesas Electronics Corporation. The 7132LA100CB represents the active product line continuation for this memory architecture.
