MX29F016TC-12

Updated: 2026-09-15

Overview

The MX29F016TC-12 is a 16Mbit (2M x 8) CMOS flash memory chip manufactured by Macronix. It features a 120ns access time and operates on a single 5V power supply, making it suitable for various embedded applications. This flash memory device uses a NOR architecture, allowing for random access to memory locations. It is commonly used in systems where non-volatile storage is required, such as firmware storage in industrial control systems, networking equipment, and consumer electronics.

Structure and Working Principle

The MX29F016TC-12 is organized as 2,097,152 words of 8 bits each. It uses floating gate technology to store data, with each memory cell consisting of a transistor that can be electrically programmed and erased. The chip communicates with the host system through a parallel interface, supporting standard microprocessor read and write cycles. Data retention is typically 10 years, and the device can withstand at least 100,000 erase/program cycles per sector.

Key Features

Key features include a wide operating voltage range of 4.5V to 5.5V, low power consumption (30mA active current typical), and a standby current of less than 100μA. The device offers hardware data protection with a VPP pin for write protection and a toggle bit feature for detection of program or erase cycle completion. It also supports sector erase (4K bytes per sector) and chip erase operations.

Application Areas

The MX29F016TC-12 is widely used in embedded systems for storing firmware, configuration data, and application code. Common applications include industrial automation equipment, networking devices, and consumer electronics. In industrial settings, it's often found in programmable logic controllers (PLCs) and human-machine interfaces (HMIs). In consumer products, it may be used in set-top boxes, printers, and other devices requiring non-volatile storage.

Maintenance and Precautions

Proper handling is crucial to prevent damage from electrostatic discharge (ESD). Always use grounded wrist straps and work on ESD-safe surfaces when handling these components. During system design, ensure proper decoupling capacitors are placed near the power pins. Follow the manufacturer's recommended timing diagrams for read and write operations to ensure reliable performance. Avoid exceeding the maximum ratings specified in the datasheet.

B2B Procurement Guide

When procuring MX29F016TC-12 chips, verify the manufacturer's authenticity to avoid counterfeit components. Macronix is the original manufacturer, but the part may also be available through authorized distributors. Consider ordering samples for testing before large-scale purchases. Check for RoHS compliance if required for your application. For high-volume purchases, negotiate pricing and lead times with suppliers, as these can vary based on market conditions.
