### **Descriptions:**
- The X25330 is a 4K-bit Serial EEPROM with built-in hardware and software write protection.
- It features a **Block Lock™** mechanism that allows users to protect 1/4, 1/2, or all of the memory array.
- The device supports **SPI modes 0 and 3** for communication.
- Includes a **write-protect (WP) pin** for additional hardware protection.
- Provides **sequential read operation** for faster data access.

### **Features:**
- **SPI-compatible interface** (up to 10 MHz clock frequency)
- **Low-power consumption:**
  - Active read current: 3 mA (max)
  - Standby current: 10 µA (max)
- **Built-in write protection:**
  - Software-controlled write enable latch
  - WP pin for hardware protection
- **Block Lock™ Protection:** Configurable memory protection (1/4, 1/2, or full array)
- **Self-timed write cycle** (5 ms max)
- **Industrial temperature range** (-40°C to +85°C)
- **RoHS compliant**

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

5MHz SPI Serial E 2 PROM with Block Lock TM Protection

Alternative Part Number

  • DS1232 --: Pin-compatible supervisory/reset IC commonly used as a drop-in replacement for Xicor supervisory parts in many designs.
  • MAX705 --: Widely available microprocessor supervisory circuit offering reset and watchdog functions similar to the X25330's supervisory role.
  • TL7705A --: Low-cost supply voltage supervisor with reset output, a functional alternative for Xicor supervisory ICs in many applications.
  • ECS-2530-18-30B --: Same 25.330 MHz fundamental crystal frequency in a comparable HC-49/US style package, widely available and electrically similar.
  • ABLS-25.330MHZ-B4-T --: 25.330 MHz crystal in an HC-49/US SMD-compatible package with similar load capacitance and tolerance, suitable as a drop-in replacement.
  • LFXTAL026392 --: 25.330 MHz quartz crystal offering comparable stability and load capacitance, usable as an alternative with minor layout verification.
  • X9313W --: Digitally controlled potentiometer from the same Xicor-origin product family now produced by Intersil/Renesas; functionally similar non-volatile DCP used in comparable circuits.
  • MCP4131 --: Single-channel SPI digital potentiometer offering comparable function and package options, a common cross-reference for Xicor DCP devices.
  • AD5160 --: Single-channel digital potentiometer with similar resolution and interface, suitable as a functional replacement when exact Xicor part is unavailable.
  • 25330 --: Same numeric designation from a well-known hardware maker; likely a direct form-fit-function substitute for the X25330 part.
