Overview
M30042040108X0PWAY from Renesas is a 4Mb serial STT-MRAM non-volatile memory IC with QSPI interface, 108MHz SDR operation, 1.71–2.0V supply, industrial-plus temperature range (−40°C to +105°C), and 8-pad DFN (WSON) package. It delivers SRAM-compatible read/write timing with persistent data retention, enabling real-time logging in factory automation controllers.
For engineers reviewing the M30042040108X0PWAY datasheet, M30042040108X0PWAY pinout, M30042040108X0PWAY application, or M30042040108X0PWAY equivalent, key selection considerations include its 108MHz SDR QSPI speed, hardware/software write protection, 256-byte augmented storage array, JEDEC reset support, and industrial-plus thermal rating for embedded control systems.
Technical Context
This MRAM uses 40nm pMTJ spin-transfer torque technology to achieve true random access with zero write latency penalty and >1015 endurance cycles. Its architecture supports Execute-In-Place (XIP) mode, reducing command overhead during burst reads and enabling deterministic timing in real-time firmware execution.
The device implements dual protection: hardware-based via WP# pin and software-configurable block protection through status and configuration registers. It supports Deep Power Down (3µs entry, 400µs exit) and Hibernate modes while preserving register state and memory contents across low-power transitions.

FAQ
What is the maximum clock frequency supported by M30042040108X0PWAY in Single Data Rate mode?
M30042040108X0PWAY supports up to 108 MHz in Single Data Rate (SDR) mode. This allows sustained read/write throughput of 108 MB/s in single-line SPI and 432 MB/s in quad I/O (4-4-4) configuration. The 108 MHz rating is guaranteed across the full −40°C to +105°C industrial-plus temperature range and 1.71–2.00 V supply voltage, making M30042040108X0PWAY suitable for high-performance embedded control applications where timing predictability is critical.
Does M30042040108X0PWAY require an external backup battery or capacitor for data retention?
No, M30042040108X0PWAY does not require any external backup components. As a magnetoresistive RAM (MRAM) device, it retains data indefinitely without power due to its intrinsic non-volatility. The 20-year data retention specification at +105°C is achieved solely through STT-MRAM physics-no battery, supercapacitor, or charge-pump circuitry is needed. This eliminates maintenance, leakage current, and reliability risks associated with backup power schemes in M30042040108X0PWAY deployments.
How is write protection implemented on M30042040108X0PWAY?
M30042040108X0PWAY implements dual-layer write protection: hardware-based via the dedicated WP# pin (active-low, disables status register writes when enabled), and software-based via configuration bits in the Status Register (BPSEL[2:0], TBSEL, SNPEN). Both mechanisms can be used independently or concurrently. The WP# pin must be actively driven-not left floating-and is only functional in single SPI mode. Software protection allows fine-grained block locking of the main memory array and augmented storage sections, giving designers flexible security options without hardware changes to M30042040108X0PWAY's PCB layout.
Can M30042040108X0PWAY be used in Execute-In-Place (XIP) mode?
Yes, M30042040108X0PWAY supports Execute-In-Place (XIP) mode, allowing microcontrollers to execute code directly from the MRAM array without copying to internal RAM. XIP is enabled by sending a special command byte (0xAxh) after the address during read operations. This eliminates instruction fetch latency and reduces external memory bandwidth demand. XIP functionality is fully supported in all QSPI modes and operates reliably across the full industrial-plus temperature range, making M30042040108X0PWAY ideal for resource-constrained real-time systems where deterministic code execution is required.
What package type and dimensions does M30042040108X0PWAY use?
M30042040108X0PWAY uses an 8-pad DFN (WSON) package measuring 5.0 mm × 6.0 mm with an exposed thermal pad. This compact footprint is pin-compatible with industry-standard SOIC-8 packages but occupies 40% less board area and offers superior thermal performance. The WSON package is RoHS and REACH compliant, qualified for lead-free reflow profiles, and designed for automated assembly in high-volume industrial manufacturing. Its small size and thermal efficiency make M30042040108X0PWAY well-suited for space-constrained applications such as modular I/O cards and portable medical devices.
