AK6420AM

Memory IC Overview

The AK6420AM is a 2Kbit serial CMOS EEPROM fabricated using advanced non-volatile memory technology. It features a 128 x 16 bit organization and communicates via an SPI-compatible interface with a maximum clock frequency of 1 MHz. The device operates across a wide supply voltage range of 1.8V to 5.5V, utilizing an integrated charge pump for write operations. It is housed in an 8-SSOP surface-mount package and supports an operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Integrated charge pump circuit eliminates the need for external high-voltage generation components during write cycles.
• Supports direct interface with one-chip microcomputer serial communication ports without additional level shifting.
• Includes automatic write cycle time-out and auto-erase functions to ensure reliable data programming.
• Provides hardware and software controlled write protection mechanisms to prevent unintended data modification.

Memory IC Applications

• Low density data storage for portable electronic devices
• Configuration parameter storage in embedded systems
• Calibration data retention for sensor modules

Memory IC Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to potential availability constraints. Confirm package variant matches design requirements as suffixes may indicate specific tape-and-reel configurations. Review datasheet revisions for any updates to electrical characteristics or mechanical dimensions before finalizing procurement specifications.

Memory IC Selection Notes

Select this component when a small footprint serial EEPROM is required for storing infrequently updated configuration data. Ensure the system voltage remains within the 1.8V to 5.5V operational window. Consider the 1 MHz speed limit if high-throughput data logging is necessary, as faster alternatives exist. Verify that the 8-pin SSOP package fits the PCB layout constraints.

Memory IC Part Context

The AK6420A series belongs to a family of serial CMOS EEPROMs that includes higher capacity variants like the AK6440A and AK6480A. These devices share similar interface protocols and physical packaging options, allowing for scalable design architectures. The AK6420AM specifically targets applications requiring 2Kbit of non-volatile storage with low power consumption and high reliability standards.

Memory IC Replacement Considerations

Cross-reference tools suggest checking for functional equivalents from other manufacturers offering 2Kbit serial EEPROMs with SPI interfaces. Verify pin compatibility and voltage ranges before substitution. Note that while some distributors list cross-references, official replacement part numbers are not explicitly confirmed in public documentation.
