X28HC256PIZ-15 - Renesas Electronics

Description: The X28HC256 is a second generation high performance CMOS 32k x 8 EEPROM. It is fabricated with Intersil’s proprietary, textured poly floating gate technology, providing a highly reliable 5V only nonvolatile memory. The X28HC256 supports a 128-byte page write operation, effectively providing a 24μs/byte write cycle, and enabling the entire memory to be typically rewritten in less than 0. 8s. The X28HC256 also features DATA polling and Toggle bit polling, two methods of providing early end of write detection

X28HC256PIZ-15 Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the X28HC256PIZ-15 is 2.7V to 3.6V.
  • The HOLD pin should be pulled high during power-up and power-down sequences to prevent unwanted data changes.
  • The maximum clock frequency for the X28HC256PIZ-15 is 15 MHz.
  • To ensure data retention during power-down, the VCC pin should be lowered to 0V or a voltage below 1.5V, and the CE pin should be held high.
  • The WP pin is used to enable or disable the write protection feature. When WP is low, the device is in write-protect mode, and when WP is high, the device is in normal operation mode.
