Overview

The MX25L1606EM1I-12G is a 16Mbit (2M x 8) Serial NOR Flash memory IC designed for high-performance data storage and code execution. It operates over a 2.7V to 3.6V supply range and supports standard SPI as well as Dual Output mode for increased throughput. With an 86 MHz clock frequency and efficient low-power modes, it is a reliable choice for buffering and non-volatile storage in embedded designs.

Why Choose This Part

This memory provides a balance of performance and efficiency with its 86 MHz clock speed and a low 15uA standby current. The 4KB uniform sector erase architecture allows for granular updates, while the integrated 512-bit secured OTP provides a location for unique device identification.

Applications

Microcontroller Firmware Storage
Storing executable boot code and application firmware for MCUs lacking sufficient internal flash.
Data Logging
Recording sensor data and system logs in battery-powered IoT devices utilizing the deep power-down mode to conserve energy.
FPGA Bitstream Configuration
Holding configuration bitstreams for FPGAs that load their logic fabric via SPI at power-up.
User Interface Assets
Storing fonts, small bitmaps, and localized string tables for small embedded displays.

Getting Started

Interfacing requires a standard SPI bus (Mode 0 or 3) with a chip select line. Engineers should implement the 256-byte page programming and utilize the Status Register to poll for the 'Write In Progress' bit after erase or program operations. Most microcontroller HALs or libraries like LittleFS can be configured for this part by defining the 4KB sector size and 16Mbit capacity.
