25LC160DT-H/SN

Overview

The Microchip Technology 25LC160DT-H/SN is a 16 Kbit (2,048 x 8-bit) Serial Electrically Erasable PROM (EEPROM). It operates within a supply voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 5 MHz. The device utilizes an SPI-compatible serial bus architecture with separate data in (SI) and data out (SO) lines. It features self-timed erase and write cycles with a maximum duration of 6 ms. The component is housed in an 8-Lead SOIC package and is rated for an extended temperature range from -40°C to +150°C.

Feature Summary

• Supports byte-level and page-level write operations with a 32-byte page size.
• Includes built-in write protection mechanisms such as power-on/off data protection and a hardware write-protect pin.
• Features a hold input that allows suspension of serial communication without resetting the sequence.

Applications

• Data logging in industrial environments requiring high-temperature operation
• Configuration storage for microcontroller systems
• Parameter retention in automotive electronics

Procurement Notes

Verify the specific ordering suffix 'H' confirms the extended temperature grade (-40°C to +150°C) and 'SN' indicates the 8-Lead SOIC package. Confirm RoHS compliance status through official manufacturer documentation or certified distributor declarations prior to procurement.

Selection Notes

Select this component when application requirements demand non-volatile memory with high thermal stability up to +150°C. Ensure the system interface supports the standard SPI protocol and that the 5 MHz maximum clock speed aligns with the master controller's capabilities.

Part Context

This part belongs to the 25LCXXX family of mid-density serial EEPROMs manufactured by Microchip Technology. The family shares common architectural features including SPI compatibility and block write protection, differentiated primarily by density, package type, and operating temperature ranges.

Replacement Considerations

Compatible substitutes within the same family include 25LC160D-H/SN for identical specifications. For lower temperature grades, 25LC160C-H/SN may be considered if thermal constraints allow.
