What are the key features of 47C16-I/SN?
- 16 Kbit (2 KB) combined EEPROM and SRAM in a single SOIC-8 package saves board space
- Non-volatile EEPROM retains data without power, while SRAM enables fast 400 ns random-access reads
- I2C-compatible 2-wire interface simplifies connection to any microcontroller with minimal GPIO pins
- Industrial temperature range and JESD-609 e3 RoHS compliance for robust embedded designs
What is 47C16-I/SN used for?
The 47C16-I/SN is ideal for embedded systems that need both fast working memory and non-volatile parameter storage in a single chip, such as smart sensors, industrial controllers, and HVAC modules storing calibration data. Its 2-wire I2C interface and 16 Kbit capacity make it a practical choice for microcontroller-based designs requiring firmware configuration retention across power cycles without the complexity of a separate EEPROM and SRAM combination.

Frequently Asked Questions
How much total memory does the 47C16-I/SN provide and how is it divided between EEPROM and SRAM?
The 47C16-I/SN offers 16384 bits (16 Kbit, 2 KB) of total memory density, integrating both EEPROM for non-volatile storage and SRAM for fast volatile working memory in one 8-pin package. This combination allows embedded systems to retain configuration data across power cycles while still having rapid read-write access for runtime variables.
What is the maximum access time for the 47C16-I/SN and which microcontroller speeds does it support?
The 47C16-I/SN specifies a maximum access time of 400 ns, which is compatible with microcontrollers running at clock speeds up to several MHz on a standard I2C bus. At the typical 400 kHz fast-mode I2C clock, each byte transfer takes about 2.5 µs, well within the device timing budget for sequential reads and writes.
Why choose the 47C16-I/SN over a standalone EEPROM like 24LC16 for an IoT sensor node?
The 47C16-I/SN combines 16 Kbit EEPROM non-volatile storage with integrated SRAM in a single SOIC-8 footprint, eliminating the need for a separate SRAM chip and reducing BOM count by at least 1 component. For IoT sensor nodes with tight board space constraints and 2-wire I2C buses, this integration saves approximately 3 mm by 5 mm of PCB area compared to two discrete memory packages.
What package does the 47C16-I/SN come in and is it compatible with standard SOIC-8 footprints?
The 47C16-I/SN is housed in an SOIC-8 package (Microchip package code SOIC-8, JEDEC code R-PDSO-G8) with 8 pins on a 1.27 mm pitch. This standard footprint is directly compatible with the vast majority of SOIC-8 PCB land patterns, allowing it to drop into existing board designs that used other 8-pin EEPROM or memory devices.
