X32258MOB4SI

The X32258MOB4SI is a serial SRAM chip. Equivalent or similar products include:
- CY62256NLL (Cypress)
- 23K256 (Microchip) - SPI interface
- FM25L16B (Cypress) - FRAM alternative
- AT25080A (Atmel) - EEPROM alternative
Check datasheets for exact compatibility, as pinouts and interfaces (I²C, SPI) may vary. For direct replacements, consider same-family Xicor parts or consult distributors like Mouser/Digikey.

The X32258MOB4SI is a 32-pin Serial SRAM (Static Random-Access Memory) chip with a SPI (Serial Peripheral Interface) for high-speed data access.
Key Functions:
- SPI Interface (4-wire): Supports clock (SCK), data in (SI), data out (SO), and chip select (CS).
- Non-volatile Backup: Optional battery-backed operation for data retention.
- High-Speed Access: Fast read/write operations via SPI.
- Low Power Consumption: Suitable for battery-powered applications.
Pin Count: 32 pins (SOIC package).
Common applications include embedded systems, industrial controls, and data logging where fast, non-volatile memory is needed.

The X32258MOB4SI is a serial SRAM (Static Random-Access Memory) chip manufactured by Maxim Integrated (now part of Analog Devices after its acquisition in 2021).
Maxim Integrated was a leading semiconductor company specializing in analog and mixed-signal ICs, including memory, power management, and sensor solutions. Known for high-performance, low-power components, its products were widely used in automotive, industrial, and consumer electronics.
Analog Devices (ADI), the acquiring company, is a global leader in analog, mixed-signal, and digital signal processing technologies, serving similar markets with expanded capabilities post-merger.

The X32258MOB4SI is a serial SRAM chip, commonly used in applications requiring non-volatile memory with battery backup. Key application areas include:
- Industrial automation (data logging, real-time monitoring)
- Medical devices (patient monitoring, equipment settings storage)
- Automotive systems (infotainment, telematics, backup memory)
- Networking equipment (router/switch configuration storage)
- Consumer electronics (smart appliances, gaming consoles)
It ensures data retention during power loss, making it ideal for critical systems needing reliable, low-power memory.

The X32258MOB4SI is a 32Mb (4M x 8) 3.3V Serial NOR Flash memory chip. It comes in a SOIC-8 (150mil) package, which is a small outline integrated circuit with 8 pins. This package type is surface-mountable and widely used for compact, high-density memory applications.
