Microchip Technology's PIC93LC46/P EEPROM

The PIC93LC46/P is a high-quality EEPROM (Electrically Erasable Programmable Read-Only Memory) device from Microchip Technology, renowned for its reliability and ease of use. This particular model is part of the 93XX series of memory products designed to provide a flexible and cost-effective storage solution for a wide range of applications.

With an organization of 64 x 16 bits, the PIC93LC46/P offers a total storage capacity of 1 Kbit, which is ideal for storing configurations, calibration data, and small application parameters that need to be preserved between power cycles. It operates on a voltage range of 4.5V to 5.5V, which aligns with the common voltage levels used in many microcontroller-based systems.

The device supports a simple 3-wire serial interface that is compatible with the SPI protocol, making it straightforward to integrate into existing designs. This interface ensures that the PIC93LC46/P can be easily connected to most microcontrollers and processors, allowing for seamless read and write operations.

One of the key features of the PIC93LC46/P is its self-timed erase and write cycles, which means that no external timing is required for write operations. This simplifies the design and reduces the complexity of the software needed to control the EEPROM. Additionally, the device boasts a write cycle time of just 5 ms, enabling quick updates to the stored data.

The PIC93LC46/P is available in a PDIP (Plastic Dual In-line Package) form factor, which is well-suited for through-hole mounting techniques. This packaging option is particularly beneficial for prototyping and small-scale production, as it allows for easy handling and soldering onto a variety of PCB (Printed Circuit Board) designs.

For data protection, the PIC93LC46/P includes a write protection feature that can be activated through the software. This prevents accidental overwrites and ensures the integrity of the data stored within the device. Furthermore, the EEPROM is designed for high endurance with a minimum of 1,000,000 write cycles and a data retention period of over 100 years, guaranteeing long-term reliability for applications that require frequent data updates.

Overall, the PIC93LC46/P from Microchip Technology is a robust and versatile EEPROM solution that provides stable and secure storage for a variety of electronic applications.
