Frequently Asked Questions
What is the capacity and organization of the 24LC32A-I/SN?
The 24LC32A-I/SN provides 32 Kbits of EEPROM storage organized as 4,096 bytes (4K x 8-bit). It communicates over a standard I2C serial bus at up to 400 kHz, requiring only two signal lines (SDA and SCL) for full read/write access.
How many write cycles does the 24LC32A-I/SN support?
The 24LC32A-I/SN supports 1,000,000 write/erase cycles of endurance per memory cell, providing excellent reliability for applications that update stored data frequently. Combined with a 200-year minimum data retention rating, it is suitable for long-life embedded systems.
How many 24LC32A-I/SN devices can share a single I2C bus?
Up to 8 devices of the 24LC32A-I/SN can be connected to a single I2C bus simultaneously. Each device is addressed using the I2C control byte pattern 1010DDD, where the three DDD bits are set by hardware address pins A0, A1, and A2 on the package.
What is the supply voltage range of the 24LC32A-I/SN?
The 24LC32A-I/SN operates from a minimum supply voltage of 2.5 V, making it compatible with modern low-voltage microcontrollers and SoCs. The factory lead time is approximately 24 weeks, so early procurement planning is recommended for production schedules.
