The 93LC46A-I/ST is a non-volatile EEPROM memory IC from Microchip Technology with a storage capacity of 1 Kbit organized as 128 x 8 bits. It communicates via the Microwire serial interface, which requires only a few pins for data transfer, making it suitable for space-constrained designs.
Operating from a supply voltage range of 2.5V to 5.5V, this device is compatible with both 3.3V and 5V systems. It features a maximum clock frequency of 2 MHz and a write cycle time of 6 ms. The IC supports self-timed erase/write cycles and includes automatic erase-all-before-write-all functionality, simplifying firmware integration.
The EEPROM is rated for an operating temperature range of -40°C to +85°C, making it suitable for industrial applications. It is offered in a surface-mount 8-TSSOP package (0.173" body width, 4.40mm pitch), which is well-suited for high-density PCB layouts.
With data retention exceeding 200 years and endurance of 1 million erase/write cycles, the 93LC46A-I/ST provides reliable long-term storage for configuration parameters, calibration data, and small application logs.
