25LC160C-I/MS

Overview

The Microchip Technology 25LC160C-I/MS is a 16 Kbit Serial Electrically Erasable PROM featuring a 2048 x 8-bit organization. It utilizes an SPI-compatible serial bus with a maximum clock frequency of 10 MHz at VCC ≥ 4.5V. The device operates within a voltage range of 2.5V to 5.5V and supports a 16-byte page size. It is housed in an 8-lead MSOP package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports sequential read operations and self-timed erase/write cycles with a maximum duration of 5 ms.
• Includes built-in write protection mechanisms such as power-on/off data protection, a write enable latch, and a dedicated write-protect pin.
• Features block write protection allowing selection of none, one-quarter, one-half, or the entire array for protection.

Applications

• Microcontroller systems requiring non-volatile data storage via SPI interface
• Industrial control applications operating within specified temperature ranges
• Embedded systems needing hardware-level write protection capabilities

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) and 'MS' denotes the MSOP package. Confirm RoHS compliance status through official documentation. Ensure the design accounts for the 16-byte page write limitation where data wrapping occurs across page boundaries.

Selection Notes

Select this component when a 16 Kbit capacity with SPI interface is required. The 'C' variant specifies a 16-byte page size, distinct from the 'D' variant's 32-byte page. Ensure the system voltage aligns with the 2.5V to 5.5V operating range. Verify that the MSOP package fits the available PCB footprint constraints.

Part Context

This part belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs from Microchip Technology. The family shares core electrical characteristics but differs in page size ('C' vs 'D') and voltage thresholds ('AA' vs 'LC'). The 25LC160C series specifically targets applications requiring a minimum supply voltage of 2.5V.
