Working Principles

CY14B104LA-ZS20XI is a serial EEPROM that utilizes the SPI interface for communication. It stores data in non-volatile memory cells, which retain information even when power is removed. The chip select (CS) pin is used to enable or disable the device, while the serial clock (SCK) synchronizes data transfer. Data is sent and received through the serial input (SI) and serial output (SO) pins, respectively. Write protection (WP) can be enabled to prevent accidental modification of stored data.

Detailed Application Field Plans

• Embedded systems: Used for storing configuration settings, calibration data, and firmware updates.
• Consumer electronics: Suitable for applications requiring small form factor and low power consumption, such as wearables, IoT devices, and portable media players.
• Automotive: Used for storing critical data like vehicle identification numbers (VINs), mileage, and diagnostic information.
• Industrial automation: Ideal for storing parameters, log data, and system configurations in industrial control systems.
