Frequently Asked Questions
What is the memory capacity and interface of the 93AA56BT-I/OT?
The 93AA56BT-I/OT provides 2Kbits of non-volatile EEPROM storage organized as 256 x 8 bits, accessible via a 3-wire Microwire-compatible SPI serial interface. It supports clock frequencies up to 1MHz, enabling straightforward integration with a wide range of microcontrollers and application-specific ICs.
What operating voltage does the 93AA56BT-I/OT require?
The 93AA56BT-I/OT operates at 1.8V, which is compatible with modern low-power microcontrollers and SoCs. This low operating voltage helps reduce total system power consumption, extending battery life in portable, wearable, and IoT applications that use the device.
How durable is the 93AA56BT-I/OT in terms of write cycles and data retention?
The 93AA56BT-I/OT is rated for a minimum of 1,000,000 write/erase cycles per byte and guarantees at least 200 years of data retention once written. These specifications make it a highly reliable choice for applications that frequently update stored data, such as calibration logging and event counters.
What package does the 93AA56BT-I/OT use and is it RoHS compliant?
The 93AA56BT-I/OT is packaged in a 6-pin SOT-23 surface-mount package, one of the smallest EEPROM footprints available, making it ideal for high-density PCB layouts. It is fully RoHS compliant (Pb-free, JESD-609 code e3) and supplied on tape and reel for automated assembly.
