Microchip 93LC46BT-I/OT 1Kbit Microwire Serial EEPROM SOT-23

The Microchip 93LC46BT-I/OT is a 1Kbit (64 x 16-bit) serial Electrically Erasable Programmable Read-Only Memory (EEPROM) employing the industry-standard 3-wire Microwire interface. Designed for low-power, nonvolatile memory applications, it operates with a clock frequency of up to 2MHz and supports a supply voltage range from 2.5V to 5.5V. This device utilises advanced CMOS technology for reliable, efficient data storage.

Key Features

• Self-timed erase/write cycles for simplified operation
• Automatic erase all (ERAL) before write all (WRAL)
• Power ON/OFF data protection circuitry
• Industrial standard 3-wire serial I/O
• Device status signal for read/write monitoring
• Sequential read function for efficient data access
• 1,000,000 erase/write cycles endurance
• Data retention greater than 200 years

The 93LC46BT-I/OT is housed in a compact SOT-23 surface-mount package with 6 pins, making it suitable for space-constrained designs. Its wide operating temperature range (-40°C to +85°C) ensures reliable performance in demanding environments. Ideal for applications in computers, computer peripherals, industrial systems, communications networking, consumer electronics, and automotive electronics, this EEPROM provides robust, long-lasting data storage.
