Frequently Asked Questions (FAQ)
What is the AT25128A-10TI-1.8 EEPROM memory IC used for?
The AT25128A-10TI-1.8 is a 128Kbit non-volatile EEPROM memory IC manufactured by Microchip Technology, designed for applications requiring reliable data storage with SPI interface connectivity. It's commonly used in embedded systems, microcontrollers, and IoT devices that need persistent memory at low power consumption. With its compact 8-TSSOP package and wide voltage range, it's ideal for portable and battery-powered applications.
What are the key specifications of the AT25128A EEPROM chip?
The AT25128A features 128Kbit storage capacity organized as 16K x 8, operates at up to 20 MHz clock frequency, and supports a wide supply voltage range from 1.8V to 5.5V. It has a 5ms write cycle time per page and operates reliably across temperatures from -40°C to 85°C, making it suitable for industrial and consumer applications.
Is the AT25128A-10TI-1.8 compatible with my microcontroller or development board?
Yes, the AT25128A uses a standard SPI (Serial Peripheral Interface) for communication, which is widely supported by most modern microcontrollers, development boards, and embedded systems. Its 8-TSSOP surface-mount package integrates easily into PCB designs, though you'll need appropriate SPI pins and a compatible driver for your specific platform.
What is the difference between this EEPROM and other memory types?
Unlike volatile RAM that loses data when powered off, the AT25128A is a non-volatile EEPROM that permanently retains stored data even without power. Compared to Flash memory, EEPROM offers better write-cycle endurance for frequent updates in smaller capacity applications. Its SPI interface also consumes less board space and power than parallel memory alternatives.
What are the operating voltage and temperature ranges for this chip?
The AT25128A operates with a supply voltage between 1.8V and 5.5V, allowing compatibility with both modern low-power and legacy systems. Its wide operating temperature range from -40°C to 85°C makes it suitable for automotive, industrial, and consumer-grade applications in harsh environments.
Quality Assurance (QC)
DiGi ensures the quality and authenticity of every electronic component through professional inspections and batch sampling, guaranteeing reliable sourcing, stable performance, and compliance with technical specifications, helping customers reduce supply chain risks and confidently use components in production.
