Frequently Asked Questions
What clock frequency does the 24LC024H-I/ST support, and how does that affect data transfer speed?
The 24LC024H-I/ST supports I2C clock frequencies up to 1 MHz in Fast-mode Plus operation. At 1 MHz, an 8-byte page write completes in approximately 80 µs, making it suitable for applications that need quick non-volatile storage updates without a high-speed parallel bus.
How many write cycles can the 24LC024H-I/ST handle before it wears out?
Microchip specifies a minimum endurance of 1,000,000 write/erase cycles for the 24LC024H-I/ST. Even with frequent parameter updates at one write per second, this equates to over 11 days of continuous cycling, and in typical embedded use the device will last the product's entire lifetime.
Which supply voltage range makes the 24LC024H-I/ST compatible with both 3.3V and 5V microcontrollers?
The 24LC024H-I/ST operates from a 2.5V to 5.5V supply, making it directly compatible with 3.3V ARM Cortex-M systems and legacy 5V AVR or PIC microcontrollers without any level-shifting circuitry. This flexibility reduces BOM complexity in mixed-voltage designs.
In what applications does the TSSOP-8 package of the 24LC024H-I/ST offer an advantage over DIP-8?
The TSSOP-8 package measures approximately 3 mm x 4.4 mm, using over 60% less board area than an 8-pin DIP package. This compact footprint is critical in space-constrained applications such as wearable sensors, smart cards, and miniaturized data-logger modules where PCB real estate is at a premium.
