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 2048 x 8 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.
The 47L16 EERAM has a 2.7-3.6V operating voltage range and is available in 8-lead SOIC, TSSOP and PDIP packages. The EERAM works from -40C to 125C and is automotive grade qualified.
MPLAB® X Integrated Development Environment (IDE) is an expandable, highly configurable software program that incorporates powerful tools to help you discover, configure, develop, debug and qualify embedded designs for most of Microchip’s microcontrollers, microprocessors and digital signal controllers.
MPLAB X IDE works seamlessly with the MPLAB development ecosystem of
The MPLAB® PM3 Universal Device Programmer is easy to use and operates with a PC or as a stand-alone unit, and programs Microchip's entire line of PIC® devices as well as the latest dsPIC® DSC devices. When used standalone, data can be loaded and saved with the SD/MMC card (not included).
The EERAM I²C PICtail™ Kit demonstrates the features and abilities of the 47C04 and 47L16 I²C EERAM devices in standard development platforms. By designing this daughter board with the PICtail Plus and mikroBUS™ connectors, it will operate with the Explorer 8 Development Board, the Explorer 16/32 Development Board, and many other tools.
