The 48L512 is a 512-Kbit SPI serial EERAM with an SRAM array organized as 65,536 × 8 bits and hidden EEPROM backup that automatically preserves and restores data during power disruptions. It operates over a 2.7V to 3.6V supply range with an industrial temperature range of -40°C to +85°C. The device supports SPI communication up to 66 MHz with Schmitt trigger inputs for noise suppression, and uses an 8-lead SOIC package. Active current is 5 mA maximum at 85°C and 3.6 V, standby current is 200 µA maximum at 85°C, and hibernate current is 3 µA maximum at 85°C. The EEPROM backup supports a minimum of 100,000 transfer cycles at 85°C and 100-year data retention at 55°C. A 47 µF to 100 µF capacitor is required on the VCAP pin for proper operation.
EERAM is an SRAM that doesn't lose its content on a power disruption. Inside each memory cell, transparent to the user, are nonvolatile transistors that capture the SRAM content and hold it through power loss events. On power restore, the SRAM is reloaded with its last content and SRAM operation can continue.
