LE25S161CA-Z1

Memory IC Overview

The LE25S161CA-Z1 is a 16 Mbit (2048K x 8-bit) serial NOR flash memory device manufactured by onsemi. It operates on a single power supply ranging from 1.65 V to 1.95 V and supports SPI interfaces in Mode 0 and Mode 3 with a maximum clock frequency of 70 MHz. The device features a WLCSP-8 package, an operating temperature range of -40°C to +90°C, and includes small sector erase capabilities for efficient parameter storage.

Memory IC Feature Summary

• Supports standard SPI modes 0 and 3 along with dual output and dual I/O read operations for enhanced data throughput.
• Includes hardware write protection via the WP pin and non-volatile block protect bits within the status register.
• Features low-power operational modes for both reading and programming to minimize energy consumption.
• Provides emergency shutdown transitions to standby state through write suspend or software reset commands.

Memory IC Applications

• Portable information devices requiring compact dimensions
• Storage of parameters or data with limited rewrite cycles
• Applications necessitating high reliability and long data retention

Memory IC Procurement Notes

Verify the specific ordering suffix CA-Z1 against official documentation to confirm package type and availability status. Confirm that the component meets required environmental specifications for the intended operating temperature range. Ensure compatibility with the system's voltage supply levels before integration.

Memory IC Selection Notes

Select this component when a 16 Mbit capacity is required in an ultra-miniature footprint. Consider the device for designs needing flexible erase granularities between 4 kB and 64 kB sectors. Evaluate the low-power modes if energy efficiency during read and program operations is a critical design constraint.

Memory IC Part Context

This part belongs to the LE25S161 series of serial flash memories licensed from Silicon Storage Technology, Inc. The series offers various package options including VSOIC8 NB, SOIC8, UDFN8, and WLCSP8. The device is designed to replace conventional EEPROMs where higher capacity and smaller size are needed.

Memory IC Replacement Considerations

Check for alternative packages within the same LE25S161 family such as LE25S161XBTAG for WLCSP8. Verify functional equivalence if substituting with other 16 Mbit SPI NOR flashes, ensuring pinout and command set compatibility.
