Product Description
Microchip's 93C46B-I/P Serial EEPROM is a high-performance, low-voltage CMOS memory device designed for non-volatile storage applications in industrial, commercial, and embedded systems. This 1kB memory chip utilizes Serial-Microwire communication protocol and features a flexible 64 x 16-bit organization, making it suitable for storing configuration parameters, calibration data, or logging critical values.
Its 8-pin SOIC package ensures compatibility with standard through-hole mounting practices, while offering compact form factor for space-constrained designs. The EEPROM operates across a supply voltage range of 4.5V to 5.5V, supporting maximum clock frequencies up to 2MHz and a rapid random access time of 200ns, ideal for applications requiring fast read/write performance.
The 93C46B-I/P integrates advanced features such as self-timed erase and write cycles, automatic erase all (ERAL) before write all (WRAL), and comprehensive power-on/off data protection. The device further implements an industry-standard 3-wire serial interface, sequential read function, and device status signal (Ready/Busy) for streamlined system integration.
Engineered for reliability, this EEPROM supports up to 1,000,000 erase/write cycles per memory location, and guarantees data retention for over 200 years. The product meets RoHS standards and covers an industrial temperature range of -40°C to +85°C, ensuring robust performance in harsh environments. Other package options are available within the Microchip 93C series for design flexibility, including PDIP, MSOP, SOT-23, DFN/TDFN, and TSSOP.
Typical applications include industrial control systems, laboratory instrumentation, automotive electronics, embedded microcontroller memory expansion, calibration storage, and configuration management in commercial equipment.
