Frequently Asked Questions
What is the memory density of the 93AA66B-I/SN?
The 93AA66B-I/SN has a memory density of 4096 bits (4K bits), organized as 512 words of 8 bits (512x8) or 256 words of 16 bits (256x16), selectable via the ORG pin to suit different data width requirements.
What is the maximum clock frequency for the 93AA66B-I/SN?
The 93AA66B-I/SN supports a maximum clock frequency (fCLK) of 1 MHz on its 3-wire serial interface, enabling straightforward integration with most microcontrollers operating at standard SPI speeds.
How many write/erase cycles does the 93AA66B-I/SN support?
The 93AA66B-I/SN is rated for 1,000,000 (one million) write/erase cycles, providing excellent endurance for applications that require frequent data updates such as configuration changes or runtime parameter storage.
What package does the 93AA66B-I/SN use?
The 93AA66B-I/SN is housed in an SOIC-8 (Small Outline IC, 8-pin) surface-mount package with JEDEC code R-PDSO-G8, making it easy to assemble on standard PCBs for both automated and manual soldering.
Is the 93AA66B-I/SN RoHS compliant and what is the lead time?
Yes, the 93AA66B-I/SN is RoHS compliant and lead-free (JESD-609 code e3). The factory lead time is approximately 23 weeks for production orders, so it is recommended to check distributor stock for immediate availability.
