MCHP25AA160A-I/SN
Overview
The 25AA160A-I/SN is a 16-Kbit Serial Electrically Erasable PROM (EEPROM) featuring a 2K x 8 organization and a high-speed SPI interface. It operates over a wide voltage range of 1.8V to 5.5V, making it suitable for both low-power battery-operated devices and standard 5V systems. With a 10 MHz clock frequency and low standby current of 1 uA, it provides efficient non-volatile storage for configuration and calibration data.
Why Choose This Part
This EEPROM offers a robust wide supply voltage range from 1.8V to 5.5V and high reliability for long-term data retention. The device features self-timed erase and write cycles with block write protection, and its 10 MHz SPI clock speed ensures rapid data access compared to standard I2C alternatives.
Applications
Key Specifications
Getting Started
To interface with this device, connect the SPI pins (CS, SCK, SI, SO) to your microcontroller and ensure the WP and HOLD pins are tied high for standard operation. Developers can use standard SPI libraries in environments like Microchip MPLAB X or Arduino IDE, ensuring the 16-byte page size is respected during write operations to prevent data corruption.
