Frequently Asked Questions
What is the endurance and data retention specification for M95320-WMN6 in automotive applications?
M95320-WMN6 guarantees 1 million erase/write cycles per memory location and 40-year data retention at room temperature, meeting the demands of automotive ECU configuration storage, odometer logging, and fault code recording over a typical vehicle lifespan of 15–20 years.
What SPI clock rate does M95320-WMN6 support and how does it affect throughput for data logging?
M95320-WMN6 operates at up to 10 MHz SPI clock frequency with 40 ns access time, enabling sequential page write throughput of approximately 160 kbytes/s. For event loggers writing 256-byte pages, this means each write completes in under 2 µs of SPI transfer time, well within typical microcontroller DMA capabilities.
Can M95320-WMN6 operate directly from a 3.3 V microcontroller without level translation?
Yes, M95320-WMN6 accepts supply voltages from 2.5 V to 5.5 V, so it connects directly to 3.3 V systems without level-shift circuitry. The SPI logic thresholds track the supply voltage, ensuring correct communication whether the host MCU runs at 2.5 V, 3.3 V, or 5 V.
How does M95320-WMN6 compare to AT25320B for a high-endurance industrial memory application?
Both M95320-WMN6 and Microchip AT25320B are 32Kbit SPI EEPROMs in SOIC-8 packages with similar 10 MHz clock rates and 1-million-cycle endurance. M95320-WMN6's 40-year data retention and 2.5 V to 5.5 V wide supply make it slightly more flexible for automotive and industrial temperature ranges, while AT25320B may offer marginal cost advantages at high volumes through alternative distribution channels.
