Frequently Asked Questions
What is the memory capacity and organization of the 24FC512-I/ST14?
The 24FC512-I/ST14 provides 512 Kbits of EEPROM storage organized as 64K x 8 bits (64,000 bytes). This capacity is sufficient for storing firmware configurations, calibration tables, and log data in embedded microcontroller systems, and multiple devices can be cascaded on the same I2C bus using different address pins.
What is the maximum clock frequency and communication interface of the 24FC512-I/ST14?
The 24FC512-I/ST14 uses the I2C serial interface with a maximum clock frequency of 1 MHz, supporting fast-mode plus operation. The I2C control byte is 1010DDDR, where the D bits are user-configurable address pins allowing up to eight devices to share the same bus without address conflicts.
What are the endurance and data retention specifications?
The 24FC512-I/ST14 is rated for one million write/erase cycles per memory location, ensuring long service life in applications that update data frequently. Data retention is a minimum of 200 years under standard operating conditions, making it suitable for applications requiring persistent non-volatile storage over the product lifetime.
What package does the 24FC512-I/ST14 use, and what is its operating voltage?
The device is housed in a 14-pin TSSOP (Thin Shrink Small Outline Package, PDSO-G14) surface-mount package, which offers a compact footprint for PCB layouts. It operates from a minimum supply voltage of 2.5V, making it compatible with low-voltage microcontroller systems and battery-powered designs.
Is the 24FC512-I/ST14 RoHS compliant, and what is its typical lead time?
Yes, the 24FC512-I/ST14 is RoHS compliant with a Pb-free designation and JESD-609 e3 rating. The factory lead time is approximately 14 weeks for direct orders, but authorized Microchip distributors typically maintain stock for immediate shipment, supporting both prototype quantities and production volume requirements.
