Description

Add memory to your project with EERAM 3.3V click. It carries the 47L16 EERAM, a 16Kbit SRAM with EEPROM Backup from Microchip. The click is designed to run on a 3.3V power supply. It communicates with the target microcontroller over I2C interface, with additional functionality provided by the INT pin on the mikroBUS™ line.

47L16 features

The Microchip Technology Inc 47L16 EERAM is a 16Kbit SRAM with EEPROM Backup. The I2C EERAM Memory is a Low-Cost NVSRAM that Eliminates the Need for an External Battery to Retain Data. The device is organized as 2048x8 bits and utilizes the I2C serial interface. The 47L16 provides infinite read and write cycles to the SRAM while the EEPROM cells provide high endurance non-volatile storage of Data. With an external capacitor, SRAM data is automatically transferred to the EEPROM upon power-loss. Data can also be transferred manually by using either the hardware store pin or by software control. Upon power-up, the EEPROM data is automatically recalled to the SRAM. Recall can also be initiated through software control. The unlimited endurance makes the EERAM useful in applications that need to constantly monitor or record data.
