Description

The 93S46DMQB is a 1K bit serial Electrically Erasable Programmable Memory (EEPROM) product. It belongs to a range of EEPROM products which include 2K and 4K bits (respectively for M93S56, M93S66, M93S46), which are collectively referred to as M93Sx6. The 93S46DMQB supports an industry-standard MICROWIRE bus and has a single supply voltage of 4.5 to 5.5V. It has a self-timed programming cycle with auto-erase and a user-defined write-protected area. The device also has a page write mode, ready/busy signal, and enhanced ESD/latch-up behavior. The 93S46DMQB has more than 1 million erase/write cycles and more than 40 years of data retention.

Comparison

• Supports an industry-standard MICROWIRE bus, making it compatible with a wide range of systems.
• Has a self-timed programming cycle with auto-erase, which simplifies the programming process.
• Offers a user-defined write-protected area and page write mode, which help protect data from accidental modification.
• Enhanced ESD/latch-up behavior increases the device's durability and reliability.
• More than 1 million erase/write cycles and more than 40 years of data retention ensure long-lasting performance and stability.

• The 93S46DMQB has a relatively small memory size of just 1K bits, which may not be sufficient for some applications.
• The device has a slower write time of 10ms compared to newer products such as the M93Sx6-W which has a write time of 5ms.
