25LC160A-E/P

Overview

The Microchip Technology 25LC160A-E/P 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 10 MHz at VCC ≥ 4.5V. The device operates within a supply voltage range of 2.5V to 5.5V and supports a 16-byte page write size. It utilizes low-power CMOS technology, offering high reliability with 1,000,000 erase/write cycles endurance and data retention exceeding 200 years. The component is housed in an 8-lead PDIP package and is rated for an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Supports standard SPI communication with separate data input and output lines.
• Includes hardware write protection via the WP pin and software block protection.
• Features self-timed erase and write cycles with automatic latch reset.
• Provides hold functionality to pause serial transmission without resetting the sequence.

Applications

• Data storage for microcontroller systems requiring non-volatile memory
• Configuration parameter storage in embedded devices
• Calibration data retention in industrial control applications

Procurement Notes

Verify that the specific part number suffix matches the required package type and temperature grade. Confirm RoHS compliance status as indicated in official documentation. Ensure the ordering quantity aligns with factory packaging constraints. Cross-reference the manufacturer's latest datasheet revision to confirm current electrical characteristics and availability status before finalizing procurement.

Selection Notes

Select this component when a 16 Kbit capacity with SPI interface is required. Choose the 'E' suffix variant specifically for automotive-grade temperature ranges up to 125°C. Consider the 16-byte page size limitation for write operations compared to other variants. Verify that the system voltage falls within the 2.5V to 5.5V operating range for reliable performance.

Part Context

This device belongs to the 25XX160A/B family of 16 Kbit Serial EEPROMs from Microchip Technology. It shares architectural similarities with the 25AA160A series but differs in minimum operating voltage requirements. The 'A' designation indicates a 16-byte page size, distinguishing it from the 'B' version which offers a 32-byte page size. It is designed for direct interfacing with popular microcontroller families.
