Key Features

  • 2 Kbit SPI EEPROM with selectable 8-bit or 16-bit word organization (256 x 8 or 128 x 16) for flexible data alignment in diverse microcontroller applications
  • Ultra-low 1.8 V supply voltage with 1 MHz SPI clock support, ideal for battery-powered and low-power embedded systems
  • 1,000,000 write/erase cycles endurance with 200-year data retention in a compact 8-pin MSOP package with RoHS-compliant lead-free construction

Applications

The 93AA56C-I/MS is designed for small non-volatile data storage in low-voltage embedded systems, including storing calibration data, device identifiers, and configuration settings in IoT sensors and wearable devices. Its 1.8 V operation and compact MSOP-8 package make it ideal for space-constrained, battery-powered applications where minimizing board area and power consumption are priorities. The flexible 8/16-bit word width organization simplifies integration with both 8-bit and 16-bit microcontroller memory architectures.

Frequently Asked Questions

What is the capacity and word width of the 93AA56C-I/MS?

The 93AA56C-I/MS provides 2 Kbits of EEPROM storage, configurable as either 256 x 8-bit (256 bytes) or 128 x 16-bit (128 words) organization. The 16-bit alternate memory width option simplifies interfacing with 16-bit MCU memory buses.

What is the minimum operating voltage of the 93AA56C-I/MS?

The 93AA56C-I/MS operates from a supply voltage as low as 1.8 V, making it compatible with modern ultra-low-power microcontrollers and SoCs. This low voltage enables use in battery-operated devices such as wearables, sensors, and portable electronics.

How many write cycles and what data retention does the 93AA56C-I/MS offer?

The 93AA56C-I/MS is rated for 1,000,000 write/erase cycles with a minimum data retention of 200 years. This exceptional combination of endurance and retention makes it suitable for applications that frequently update stored data over the full product lifetime.

What package does the 93AA56C-I/MS use?

The 93AA56C-I/MS is housed in an 8-pin MSOP (Mini Small Outline Package, S-PDSO-G8) package, one of the smallest SOIC variants available. This miniature footprint is ideal for space-constrained PCB designs. The factory lead time is approximately 12 weeks.
