MR4A16BYS35

Memory IC Overview

The MR4A16BYS35R is a magnetoresistive random access memory (MRAM) device manufactured by Everspin Technologies. It provides a storage capacity of 16 Mbit, organized as 1M x 16 words with a 16-bit data bus width. The component utilizes a parallel interface and features a 35 ns access time. It operates within a supply voltage range of 3 V to 3.6 V and supports surface mount installation in a 54-pin TSOP-II package. The device is designed for industrial temperature ranges from 0°C to +70°C.

Memory IC Feature Summary

• Provides non-volatile data retention exceeding 20 years without power.
• Offers unlimited read and write endurance capabilities.
• Includes internal single bit error correction code with 7 ECC parity bits per 64 data bits.
• Features low-voltage inhibit circuitry to protect data during power loss.

Memory IC Applications

• Applications requiring permanent storage and rapid retrieval of critical data
• Fault-tolerant design implementations
• Industrial control systems

Memory IC Procurement Notes

Verify the specific suffix against official documentation, as the provided model lacks the final character found in standard listings like MR4A16BYS35R. Confirm moisture sensitivity level compliance and ensure the ordering quantity aligns with manufacturer reel specifications. Validate that the parallel interface timing matches system requirements before procurement.

Memory IC Selection Notes

Select this component when SRAM-compatible timing is required alongside non-volatile storage. The 35 ns cycle time suits high-speed applications. Consider the 54-pin TSOP-II package for space-constrained designs. Ensure the 3.3V nominal supply voltage fits the target board architecture and that ECC handling is supported by the host processor.
