25AA160D-E/SN

Memory IC Overview

The Microchip Technology 25AA160D-E/SN is a 16 Kbit Serial Electrically Erasable PROM featuring an SPI-compatible interface. It utilizes a 2048 x 8-bit organization with a 32-byte page size, characteristic of the 'D' version devices. The component supports a maximum clock frequency of 10 MHz and operates within a supply voltage range of 1.8V to 5.5V. It is housed in an 8-lead SOIC package and is qualified for automotive applications, supporting an ambient temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Supports high-speed serial communication via a standard SPI bus with up to 10 MHz clock frequency.
• Includes built-in hardware write protection mechanisms utilizing a dedicated WP pin and status register bits.
• Features power-on/off data protection circuitry and a write enable latch to prevent inadvertent writes.
• Provides sequential read capabilities with automatic internal address pointer incrementation.

Memory IC Applications

• Automotive electronic systems requiring non-volatile memory with extended temperature tolerance
• Industrial control units needing reliable data storage under harsh environmental conditions
• Microcontroller-based embedded designs interfacing via SPI protocol

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the device meets automotive qualification standards if intended for such environments. Ensure compatibility with system voltage levels and SPI timing requirements before integration. Check datasheet revisions for any updates regarding electrical characteristics or packaging changes.

Memory IC Selection Notes

Select this part when automotive-grade reliability and wide operating temperature ranges are required. The 1.8V minimum supply voltage allows operation in low-power systems compared to 2.5V variants. The 32-byte page size offers efficient bulk writing capabilities. Consider the SOIC package for through-hole or standard surface-mount assembly processes.

Memory IC Part Context

This component belongs to the 25AA160C/D family of 16K SPI Bus Serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 25LC160 series but differs in supply voltage specifications and temperature qualifications. The 'E' suffix denotes automotive qualification, while 'SN' indicates the 8-lead SOIC package format.

Memory IC Replacement Considerations

The 25AA160D-I/SN serves as the industrial temperature equivalent. The 25LC160D-E/SN is a compatible alternative with a higher minimum supply voltage requirement of 2.5V. Verify pinout and instruction set compatibility when substituting these parts.
