Frequently Asked Questions
What is the memory organisation and maximum clock frequency of the 93LC46B-I/P?
The 93LC46B-I/P is organised as 64 words of 16 bits each, totalling 1 Kbit of EEPROM storage. Its serial interface supports clock frequencies up to 2 MHz, enabling fast read and write operations from 3.3 V or 5 V microcontrollers using a simple 3-wire or 4-wire SPI-compatible protocol.
How long will data stored in the 93LC46B-I/P persist, and how many write cycles can it handle over its lifetime?
Microchip specifies the 93LC46B-I/P for a minimum data retention of 200 years under normal storage conditions and a minimum endurance of 1,000,000 erase/write cycles. These specifications mean the device can be updated multiple times per day for many years in an industrial application without approaching its write endurance limit.
Which package does the 93LC46B-I/P use, and when is the DIP form factor preferred over an SOIC variant?
The 93LC46B-I/P comes in an 8-pin PDIP-8 through-hole package with 2.54 mm pin spacing, making it ideal for breadboard prototyping and hand-soldered PCBs. Designers prefer the DIP variant during early prototyping, for field-replaceable socketed designs, or when producing small quantities where SMT reflow equipment is unavailable or uneconomical.
For a meter calibration application that writes calibration constants only during factory programming, is the 93LC46B-I/P a good choice?
Yes, the 93LC46B-I/P is an excellent fit for a meter calibration use case where calibration constants are written once or a small number of times during factory programming. With 1 Kbit of storage, it holds dozens of 16-bit calibration coefficients, and its greater than 200-year data retention ensures stored values remain valid throughout the instrument's service life without battery backup.
