Frequently Asked Questions
What is the memory capacity and organization of the 25LC320A-I/MS?
The 25LC320A-I/MS provides 32Kbit (32,768 bits) of EEPROM storage organized as 4,096 bytes (4096x8). This byte-addressable organization allows embedded firmware to store structured data such as configuration tables, data logs, firmware version information, and user-defined settings with byte-level access granularity.
What SPI clock speed does the 25LC320A-I/MS support and what is its minimum operating voltage?
The 25LC320A-I/MS supports a maximum SPI clock frequency of 10MHz and operates at a minimum supply voltage of 2.5V. Notably, it is specified to operate at the full 5MHz speed from 2.5V, making it compatible with 3.3V and 5V systems alike without performance degradation at lower supply voltages.
What is the endurance and data retention of the 25LC320A-I/MS?
The 25LC320A-I/MS is rated for a minimum of 1,000,000 write/erase cycles per byte and provides a minimum data retention of 200 years. These ratings ensure that the device remains reliable in applications requiring frequent configuration updates, usage counters, or event logging over the full operational lifetime of the product.
What package does the 25LC320A-I/MS use and is it RoHS compliant?
The 25LC320A-I/MS is housed in an MSOP-8 (Mini Small Outline Package with 8 pins) surface-mount package, which offers a significantly smaller PCB footprint than standard SOIC-8 devices. It is fully RoHS compliant and lead-free, meeting international environmental standards for use in consumer, industrial, and automotive applications worldwide.
How does the 25LC320A-I/MS compare to I2C EEPROMs for embedded designs?
Unlike I2C EEPROMs which are limited to 400kHz (Fast Mode) or 1MHz (Fast-Plus Mode), the 25LC320A-I/MS uses a 4-wire SPI interface supporting up to 10MHz, providing significantly faster data transfer rates. SPI also allows simultaneous read and write operations in full-duplex mode, making it preferable in applications where latency or throughput is critical.
