AK6510CM Equivalent & Substitute Parts

Part Overview

The AK6510CM is a 32Kbit EEPROM memory IC with SPI interface operating at 5 MHz, manufactured by Asahi Kasei Microdevices (AKM) in an 8-SSOP package. This component is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. The part operates across a wide supply voltage range of 1.8V to 5.5V and supports industrial temperature ranges from -40°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the AK6510CM is determined by strict equivalence across the following critical parameters:

• Memory capacity: 32Kbit
• Memory organization: 4K x 8 configuration
• Interface protocol: SPI serial communication
• Supply voltage compatibility: 1.8V ~ 5.5V range
• Operating temperature range: -40°C ~ 85°C
• Mounting technology: Surface mount
• Package form factor: 8-pin SSOP/MSOP variants

The substitute part 25AA320AT-I/MS from Microchip Technology meets all functional and electrical requirements. While it operates at 10 MHz (higher than the 5 MHz specification of the AK6510CM), this represents an enhancement rather than a limitation, as the substitute maintains full backward compatibility with the original part's electrical interface and memory organization.

Parameter Comparison

Engineering Selection Recommendations

The 25AA320AT-I/MS is the primary substitute for the obsolete AK6510CM. Selection of this part is supported by:

• Active product status with verified availability (3900 units in stock)
• Full electrical parameter compatibility across all critical specifications
• Enhanced clock frequency (10 MHz vs. 5 MHz) providing performance margin
• RoHS3 compliance and REACH unaffected status, meeting modern regulatory requirements
• Identical moisture sensitivity classification (MSL 1)
• Verified DiGi-Electronics programmable status

The package transition from 8-SSOP to 8-MSOP requires PCB layout modification due to the reduced body width (3.00mm vs. 4.40mm). Pin configuration remains compatible for SPI interface connections.

Frequently Asked Questions (FAQ)

Q: Can the 25AA320AT-I/MS directly replace the AK6510CM without circuit modification?

A: The electrical interface is fully compatible. However, the package footprint differs (8-MSOP vs. 8-SSOP), requiring PCB layout changes. Pin assignments for SPI communication (MOSI, MISO, CLK, CS) remain functionally equivalent.

Q: Why does the substitute operate at 10 MHz when the original is rated for 5 MHz?

A: The higher clock frequency of the 25AA320AT-I/MS represents an enhanced specification. Systems designed for 5 MHz operation will function correctly at the lower frequency within the substitute's capability range.

Q: Are there compliance differences between the two parts?

A: The 25AA320AT-I/MS carries RoHS3 compliance and REACH unaffected status, meeting current regulatory standards. The AK6510CM, being obsolete, does not carry current compliance certifications.

Q: What is the significance of the MSL 1 rating for both parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements, simplifying storage and handling procedures for both the original and substitute components.

Q: How do the write cycle times compare?

A: The 25AA320AT-I/MS specifies a 5ms write cycle time. The AK6510CM does not provide this specification in available documentation. Both parts support standard SPI write protocols.
