**MR4A16BCMA35 – 16Mb Parallel MRAM – Everspin Technologies | Fast Shipping at PCX**

The Everspin Technologies MR4A16BCMA35 is a high-performance 16 Megabit (16Mb) Parallel Interface Magnetoresistive RAM (MRAM) module. Designed for demanding applications requiring non-volatile memory with SRAM-like speed and unlimited endurance, this MRAM IC offers a robust solution for data persistence even during power loss. PCX ensures reliable supply and rapid delivery of this advanced memory component.

**Key Features**
* **16Mb Capacity (1M x 16-bit):** Ideal for storing critical configuration data or event logs.
* **Non-Volatile Memory:** Retains data without power, eliminating the need for battery backup.
* **SRAM-like Performance:** Fast **35ns access time** ensures quick read/write operations.
* **High Reliability & Endurance:** Virtually unlimited read/write cycles (typically > 1e14) for long-term use.
* **Low Power Operation:** Single **3.3V supply voltage**.
* **Parallel Interface:** Simple integration with standard parallel memory controllers.

**Technical Details**
This MRAM device is organized as 1 Meg x 16 bits, providing a straightforward 16-bit data bus interface. It operates on a single 3.3V supply. The access time of 35ns enables it to function similarly to high-speed SRAM but with the critical advantage of non-volatility. While specific temperature range details should be confirmed via the datasheet, Everspin MRAMs are typically designed for industrial temperature ranges. Its inherent immunity to radiation and magnetic fields (within datasheet limits) enhances robustness.

**Applications**
The Everspin MR4A16BCMA35 MRAM is perfectly suited for:
1. **Industrial Automation & Control Systems:** Storing critical parameters, calibration data, and event logs safely.
2. **Automotive Electronics:** Black box data recorders, ADAS event logging, and configuration storage.
3. **Medical Devices:** Secure storage of device settings and patient data logs.
4. **Data Logging & Metering:** Reliable capture and retention of usage or event data.
5. **Networking Equipment:** Storing configuration tables and statistics persistently.

**About MRAM (Magnetoresistive Random-Access Memory)**
MRAM is a unique type of non-volatile memory that stores data using magnetic states, not electric charge (like DRAM) or trapped charge (like Flash). This fundamental difference grants MRAM significant advantages: near-infinite endurance (unlike Flash, which wears out), data retention without power, fast read/write speeds comparable to SRAM, and resilience against radiation and extreme temperatures.

These characteristics make MRAM ideal for applications requiring persistent storage of frequently updated data, where reliability, speed, and longevity are paramount. It bridges the gap between volatile SRAM/DRAM and slower, wear-limited Flash, offering a robust solution for mission-critical systems.

**Packaging Options**
PCX supplies the MR4A16BCMA35 in industry-standard packaging suitable for high-volume manufacturing. Availability of specific formats like Tape & Reel (TR), Cut Tape, or Tray can be confirmed upon inquiry or order placement. We ensure your requirements are met for seamless integration into your production line.

**Frequently Asked Questions (FAQs)**

* **Q: What is the main advantage of MRAM over Flash memory?**
A: MRAM offers virtually unlimited write endurance (billions to trillions of times more than Flash) and much faster write speeds, making it ideal for applications that frequently update stored data.

* **Q: Does this MRAM require a battery backup?**
A: No. The Everspin MR4A16BCMA35 is truly non-volatile. Once data is written, it is retained without any power source or battery backup required.

* **Q: Is this MRAM pin-compatible with standard SRAM?**
A: While it uses a parallel interface common to asynchronous SRAM, exact pin compatibility depends on the specific SRAM part being replaced. Always consult the MR4A16BCMA35 datasheet and your target SRAM datasheet for confirmation. PCX can provide the datasheet.

* **Q: What is the typical data retention period for this MRAM?**
A: Everspin MRAM products like the MR4A16BCMA35 typically offer data retention exceeding 20 years at specified operating temperatures, ensuring long-term reliability.

* **Q: Can PCX provide technical support for integrating this MRAM?**
A: While integration support is primarily the responsibility of the design engineer using the manufacturer’s datasheet, PCX can facilitate access to Everspin resources and documentation. Our customer support team is ready to assist with order and availability questions.
