Product Description
Microchip 47L16-I/ST EERAM 16 kB is a sophisticated non-volatile memory solution combining high-speed SRAM with EEPROM backup, ideal for industrial and embedded systems requiring reliable data retention without battery dependency.
This device offers a synchronous timing type and is organized as 2048k x 8 bit memory, providing 16 kB capacity with 8 bits per word. It supports a maximum clock frequency of 1000 kHz and a maximum random access time of 400 ns, enabling efficient and rapid data operations.
The memory operates with a supply voltage between 2.7 V and 3.6 V and draws a supply current of approximately 300.4 mA. It comes in a surface mount TSSOP package with 8 pins, measuring 3.1 mm in length, 4.5 mm width, and 1.05 mm height - making it a compact footprint device suitable for dense electronic assemblies.
Designed for robust performance, it withstands operating temperatures ranging from -40°C to 85°C. The hardware store pin allows manual EEPROM store operations, while software commands offer automated store and recall processes, ensuring data integrity during power transitions. The automatic transfer of SRAM data to EEPROM upon power loss (using an optional external capacitor) eliminates the need for battery-backed memory.
This Microchip EERAM is suitable for industrial automation, automotive electronics, communication devices, and data logging equipment, where persistent memory and fast SRAM access are critical.
Automatic data store and recall to EEPROM with external capacitor support. Infinite SRAM read/write cycles with high endurance EEPROM backup. Synchronous timing for high-speed data access. Compact 8-pin TSSOP surface mount package.
Wide supply voltage and temperature operating ranges. Manual and software store control for flexible memory management. Low power supply current supporting efficient system designs.
