MR0A16AVMA35

Memory IC Overview

The MR0A16AVMA35 is a 1 Mbit Magnetoresistive Random Access Memory (MRAM) device from Everspin Technologies, organized as 64K x 16 bits with a 16-bit data bus width. It features a parallel interface and a typical access time of 35 ns. The component operates within a supply voltage range of 3 V to 3.6 V and supports industrial temperature grades from -40°C to +85°C or extended ranges up to +105°C depending on specific suffix variations. It is housed in a BGA-48 package for surface mount installation.

Memory IC Feature Summary

• Provides non-volatile data retention without requiring external backup batteries or supercapacitors.
• Delivers random access speeds comparable to SRAM with no write latency constraints.
• Supports unlimited endurance cycles for write operations compared to traditional flash memory.

Memory IC Applications

• Parameter backup and configuration storage in industrial control systems
• Real-time data logging and event recording in embedded applications
• Intermediate caching in high-speed processing units

Memory IC Procurement Notes

Verify the exact operating temperature grade and package variant against the full part number suffix before ordering. Confirm moisture sensitivity level requirements and reflow soldering profiles with the manufacturer's latest documentation. Ensure compatibility with system power sequencing and write protection thresholds during design validation.

Memory IC Selection Notes

Select this model when non-volatility and high-speed random access are required without the complexity of battery-backed solutions. Compare total cost of ownership against FRAM or NVSRAM alternatives by evaluating long-term reliability and cycle endurance needs. Ensure the 16-bit parallel interface aligns with available microcontroller or FPGA resources.

Memory IC Part Context

This component belongs to the MR0A16A series of asynchronous MRAM devices designed for high-reliability applications. It utilizes spin-transfer torque technology to store data magnetically, offering robust performance in harsh environments. The series is engineered to replace volatile SRAM with non-volatile capabilities while maintaining similar timing characteristics.

Memory IC Replacement Considerations

Direct substitutes include other Everspin MRAM models such as MR0A16AMA35R or MR0A16ACMA35R, which share identical pinouts and electrical specifications but may differ in temperature ratings or packaging formats. Verify functional equivalence before substitution.
