Frequently Asked Questions
What is the maximum SPI clock speed of the 93LC46BT-I/SN and how does that affect read latency?
The 93LC46BT-I/SN supports a maximum clock frequency of 2 MHz and a 400 ns access time, allowing fast serial reads of its 128-byte (1Kbit) array in microcontroller designs operating from 2.5V to 5.5V supply rails.
How long can data stored in the 93LC46BT-I/SN persist without power, and how many write operations does it survive?
Data retention exceeds 200 years under rated conditions, and the device is guaranteed for a minimum of 1,000,000 erase/write cycles per address, making it suitable for frequent configuration saves in industrial sensors or appliance control boards.
Which supply voltages does the 93LC46BT-I/SN support, and can it interface directly with 3.3V microcontrollers?
The device operates from 2.5V to 5.5V, covering the full 3.3V and 5V logic families; at 3.3V, it connects directly to modern ARM Cortex-M or PIC microcontrollers without level-shifters, simplifying BOM and PCB layout in the 8-pin SOIC package.
For a design needing MAC address or unit serial number storage, why is the 93LC46BT-I/SN a practical choice?
Its 1Kbit (128 bytes) of non-volatile storage via a 3-wire Microwire/SPI interface, combined with SOIC-8 packaging and sub-$0.50 pricing in volume, makes it cost-effective for storing fixed identifiers written once and read at every boot across millions of units.
