AT25160BN-SH-B

Memory IC Overview

The AT25160BN-SH-B is a serial electrically-erasable programmable read-only memory (EEPROM) with a storage capacity of 16 kbit, organized as 2048 words of 8 bits each. It operates within a supply voltage range of 1.8 V to 5.5 V and supports SPI clock frequencies up to 20 MHz at 5 V. The device utilizes an 8-lead JEDEC SOIC package and functions across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports SPI Modes 0 and 3 for synchronous serial communication
• Provides hardware write protection via the WP pin and software block protection
• Features self-timed write cycles with automatic return to standby state
• Includes a HOLD pin to pause serial sequences without resetting

Memory IC Applications

• Industrial control systems requiring low-power non-volatile data storage
• Commercial applications necessitating robust data retention
• Embedded devices interfacing with 6805 or 68HC11 microcontrollers

Memory IC Procurement Notes

Verify that the ordering suffix 'N' corresponds to the specified NiPdAu lead finish and 'B' indicates bulk packaging. Confirm the package type matches the required 8-lead JEDEC SOIC footprint. Ensure the voltage option aligns with the 1.8 V to 5.5 V operational requirement for your specific circuit design.

Memory IC Selection Notes

Select this component when a 16 kbit EEPROM is required with SPI compatibility. Consider the 8-lead SOIC package for space-constrained designs. Evaluate the need for hardware write protection features if system security against inadvertent writes is critical. Verify operating temperature requirements fall within the industrial range.

Memory IC Part Context

This part belongs to the AT25080B/160B series of serial EEPROMs manufactured by Microchip Technology (formerly Atmel). The series offers various density options and package types including PDIP, TSSOP, and MLP. The AT25160B specifically provides double the memory density of the AT25080B variant.

Memory IC FAQ

How does the WP pin function affect write operations?

When the WP pin is held low and the WPEN bit is set to 1, all write operations to the status register and protected array sections are inhibited.

What is the maximum page write size supported?

The device supports a 32-byte page write operation, where the address counter increments internally for each byte received.
