Frequently Asked Questions
What is the memory capacity and organization of the 93AA86AT-I/OT?
The 93AA86AT-I/OT is a 16Kbit EEPROM organized as 2048 words by 8 bits (2048 x 8), providing 2048 bytes of non-volatile storage. This capacity is well-suited for storing device configuration data, calibration tables, security keys, and user settings in embedded systems.
What communication interface does the 93AA86AT-I/OT use?
The 93AA86AT-I/OT uses a SPI (Serial Peripheral Interface) communication protocol with a maximum clock frequency of 1MHz. The 3-wire SPI interface with chip select provides simple connectivity to microcontrollers, requiring only 4 signals: CS, CLK, SI (MOSI), and SO (MISO).
What is the operating voltage of the 93AA86AT-I/OT and why is it significant?
The 93AA86AT-I/OT operates at 1.8V, making it compatible with modern low-power SoCs and microcontrollers that use 1.8V I/O standards. This low voltage operation reduces power consumption and eliminates the need for voltage level translation between the EEPROM and 1.8V host devices.
What package does the 93AA86AT-I/OT use?
The 93AA86AT-I/OT uses a SOT-23-6 package (JESD-30 code R-PDSO-G6), which is one of the smallest available surface-mount packages with 6 pins. The OT suffix indicates this SOT-23 package variant, which has an extremely small footprint ideal for space-constrained portable and wearable device PCBs.
What are the write endurance and data retention specifications for the 93AA86AT-I/OT?
The 93AA86AT-I/OT is rated for 1 million write/erase cycles with a minimum data retention time of 200 years. These specifications ensure long-term data integrity even in applications requiring frequent updates, exceeding the product service life requirements of most industrial and consumer applications.
