Frequently Asked Questions
What is the memory density and organization of the 93AA46C-I/MS?
The 93AA46C-I/MS provides 1K bits of EEPROM storage. It supports two organizational modes: 128 words of 8 bits (128x8) or 64 words of 16 bits (64x16), selectable via the ORG pin. This flexibility allows the same device to integrate easily with both 8-bit and 16-bit microcontroller data buses, reducing the need for different EEPROM variants.
What interface does the 93AA46C-I/MS use and what is its maximum clock speed?
The 93AA46C-I/MS uses a 3-wire Microwire-compatible serial interface (CS, SK, DI/DO) and supports a maximum clock frequency of 3 MHz, which is three times faster than the typical 1 MHz rated by many comparable EEPROMs. This higher clock rate enables faster read and write operations, improving system throughput in time-sensitive applications.
What are the endurance and data retention specifications of the 93AA46C-I/MS?
The 93AA46C-I/MS is rated for 1,000,000 write/erase cycles per memory location and a minimum data retention time of 200 years. These specifications ensure reliable non-volatile data storage across the full product lifetime, even in applications with frequent updates such as event logging, meter reading, or adaptive control parameters.
What package does the 93AA46C-I/MS use and how does it compare to standard SOIC-8?
The 93AA46C-I/MS is housed in an MSOP-8 (Mini Small Outline Package, 8-pin) surface-mount package per JEDEC JESD-30 code S-PDSO-G8. MSOP-8 has a significantly smaller footprint than the standard SOIC-8 package while maintaining the same pin count and functionality. This makes it an ideal choice for miniaturized designs where board area is constrained.
Is the 93AA46C-I/MS RoHS compliant and what does the 'AA' in the part number indicate?
Yes, the 93AA46C-I/MS is RoHS-compliant (Pb-free, JESD-609 e3). In the 93xx EEPROM naming convention, 'AA' designates 1.8 V operation (low-voltage), distinguishing it from 'LC' (2.5 V) and 'C' (5 V) variants. This low operating voltage makes the 93AA46C-I/MS suitable for battery-powered and low-power 1.8 V system designs.
