The AT93C46M/TR is a 1K-bit Microwire Serial EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by HGSEMI (Hangzhou Silan Microelectronics Joint Stock Co., Ltd.). This memory device is designed for low-power, non-volatile storage in a variety of applications. The /TR suffix indicates that the device is provided in tape and reel packaging for automated assembly.

Applications:

• Consumer electronics
• Automotive electronics
• Industrial control systems
• Medical devices
• Security systems

Features:

• 1K-bit (128 x 8 or 64 x 16) EEPROM
• Microwire serial interface
• Low voltage operation (typically 1.8V to 5.5V)
• Low power consumption
• Self-timed write cycle
• High reliability and endurance

Benefits:

• Non-volatile storage: Data is retained even when power is removed.
• Easy interface: Microwire serial interface simplifies communication with microcontrollers.
• Low power operation: Suitable for battery-powered applications.
• Small size: Compact packaging allows for easy integration into small devices.
• High endurance: Withstands a large number of write cycles.

Additional Details:

The AT93C46M/TR uses a three-wire serial interface (SI, SO, SK) for communication. The device supports both 8-bit and 16-bit word organization, which can be selected through a configuration pin. Key specifications include a typical write cycle time of 5 ms, a standby current of less than 1 μA, and an operating temperature range of -40°C to +85°C. The memory array can be programmed and erased electrically, allowing for easy updates and modifications. HGSEMI provides detailed datasheets and application notes to assist designers in implementing the AT93C46M/TR in their systems, ensuring optimal performance and reliability. The tape and reel packaging (indicated by /TR) is designed for automated pick-and-place assembly processes, facilitating efficient manufacturing.
