Frequently Asked Questions
What is the memory capacity and organization of the 93LC56B-I/SN?
The 93LC56B-I/SN is a 2Kbit serial EEPROM organized as 128 words of 16 bits each (128x16). It also supports an alternate 8-bit organization (256x8), selectable via the ORG pin, giving designers flexibility to match the data width of their microcontroller or application protocol.
How many write cycles does the 93LC56B-I/SN support?
The 93LC56B-I/SN is rated for a minimum of 1 million write/erase cycles per memory location. This high endurance makes it reliable for applications where configuration or calibration data is frequently updated, such as industrial controllers, smart meters, and consumer appliances.
What interface does the 93LC56B-I/SN use and what is the maximum clock speed?
The 93LC56B-I/SN uses a 3-wire serial interface compatible with SPI, supporting clock frequencies up to 2MHz. This straightforward interface requires only three signal lines (CS, CLK, DI/DO), minimizing pin count on host microcontrollers and simplifying firmware development.
What package does the 93LC56B-I/SN use?
The 93LC56B-I/SN is available in an 8-pin SOIC (Small Outline Integrated Circuit) surface-mount package, manufacturer code SOIC-8. This compact package is compatible with standard automated PCB assembly processes and fits within tight board space constraints common in consumer and industrial electronics designs.
What are typical applications for the 93LC56B-I/SN?
The 93LC56B-I/SN is widely used to store device configuration parameters, factory calibration data, unique serial numbers, and user preferences in embedded systems. Common applications include remote controls, smart metering, automotive accessories, industrial sensors, medical devices, and point-of-sale terminals where small amounts of non-volatile memory must survive power removal.
