93LC86C
The 93LC86C is a serial EEPROM memory device manufactured by Microchip Technology, offering 1024 x 8-bit storage capacity with a low-voltage operation range of 1.7V to 5.5V. It supports industry-standard SPI-compatible serial interface protocols, enabling efficient communication with microcontrollers and other digital systems. The device features a write protection mechanism using a hardware pin (WP) and software-based write enable/disable commands, ensuring data integrity during programming operations.
This memory offers fast read access times of up to 10 μs, allowing high-speed data retrieval in real-time applications. It supports both byte-write and page-write modes—up to 16 bytes per page—which improves write efficiency and reduces overall programming time. The 93LC86C also includes built-in erase and write cycle endurance of up to 1 million cycles, making it suitable for applications requiring frequent data updates or configuration storage.
Designed for reliability, the 93LC86C operates across a wide temperature range from -40°C to +85°C, ideal for industrial, automotive, and consumer electronics environments. It consumes minimal power, with typical standby current below 1 μA and active current under 5 mA, aligning with low-power design requirements in battery-operated devices such as portable instruments, smart meters, and IoT sensors.
The 93LC86C is available in 8-pin PDIP, SOIC, and TSSOP packages, providing flexibility in PCB layout and assembly processes. Its small footprint and compatibility with standard CMOS logic levels make it easy to integrate into space-constrained designs. Additionally, the device includes internal self-timed write cycles, eliminating the need for external timing components and simplifying system-level design.
Common applications include storing calibration data, device configuration settings, firmware parameters, and user-defined variables in embedded systems. It is widely used in industrial control systems, consumer electronics, medical devices, and automotive modules where non-volatile, reliable, and low-power memory solutions are essential.
