Frequently Asked Questions
What is the memory capacity of the 24LC08B-I/MS?
The 24LC08B-I/MS has a memory capacity of 8Kbits (1,024 x 8 bits = 1KB). This is organized as 1024 bytes addressable via the I2C interface with control byte 1010XMMR. The page write buffer supports 16-byte page writes, allowing efficient bulk data programming in embedded applications.
What supply voltage does the 24LC08B-I/MS operate at?
The 24LC08B-I/MS operates over a wide supply voltage range of 2.5V to 5.5V, making it compatible with both 3.3V and 5V microcontroller systems without additional level shifting. This flexibility is particularly valuable in mixed-voltage embedded designs and battery-powered applications where supply voltage may vary.
What package does the 24LC08B-I/MS use?
The 24LC08B-I/MS is housed in an MSOP-8 (Mini Small Outline Package, 8-pin) surface-mount package. The MSOP-8 has a smaller footprint than a standard SOIC-8, making it ideal for compact PCB designs where board area is limited, such as wearable devices, portable instruments, and miniaturized sensor modules.
How many write cycles does the 24LC08B-I/MS support?
The 24LC08B-I/MS guarantees a minimum endurance of 1,000,000 write/erase cycles per page, which is sufficient for most embedded applications that update configuration or calibration data periodically. Data retention is specified at a minimum of 200 years under normal operating conditions, ensuring long-term reliability.
How does the I2C address scheme work for the 24LC08B-I/MS?
The 24LC08B-I/MS uses an I2C control byte of 1010XMMR, where the two 'M' bits serve as the most significant bits of the memory address (extending the address into the 8K address space), and 'R' is the read/write bit. Because the address bits are embedded in the control byte, external address pins (A0-A2) are not used for device selection, simplifying hardware design.
