25LC160T-I/SN

Overview

The Microchip Technology 25LC160T-I/SN is a 16 Kbit (2048 x 8-bit) Serial Electrically Erasable PROM. It features an SPI-compatible serial bus interface with a maximum clock frequency of 2 MHz and operates within a supply voltage range of 2.5 V to 5.5 V. The device supports industrial temperature ranges from -40°C to +85°C and utilizes an 8-pin SOIC package. Key electrical characteristics include a typical standby current of 500 nA, a maximum write current of 3 mA, and a self-timed write cycle time of 5 ms.

Feature Summary

• Supports block write protection for none, 1/4, 1/2, or all of the memory array
• Includes built-in power on/off data protection circuitry and a write enable latch
• Features a hold pin to pause serial communication without resetting the sequence
• Provides high reliability with over 1 million endurance cycles and greater than 200 years of data retention

Applications

• Microcontroller system data storage
• Configuration parameter storage
• Calibration data logging
• Non-volatile information retention in embedded systems

Procurement Notes

Verify that the specific ordering suffix matches the required tape and reel packaging format. Confirm the temperature grade corresponds to the intended operational environment. Ensure the voltage specifications align with the target system's power supply rails before finalizing procurement decisions.

Selection Notes

Select this component when a low-power, non-volatile memory solution with SPI compatibility is required. The 25LC160T-I/SN is suitable for applications needing moderate storage density with robust write protection features. Consider the industrial temperature rating and SOIC package dimensions during the initial hardware design phase.

Part Context

This part belongs to the 25XX160 family of 16 Kbit Serial EEPROMs manufactured by Microchip Technology. The 'T' suffix indicates tape and reel packaging, while 'I' denotes the industrial temperature range. The 'SN' suffix specifies the 8-lead Plastic Small Outline Integrated Circuit package type.

Replacement Considerations

Datasheet documentation explicitly recommends using the 25AA160A/B or 25LC160A/B series instead of this product for new designs.
