The parallel interface allows single-cycle byte reads or writes. The 4.5 V supply voltage places it in the 5 V logic family. The 28-SOIC surface-mount package keeps the board profile low and is compatible with standard reflow profiles. ## Write cycle timing and endurance The write cycle time is 5 ms per word or page — a byte write ties up the bus for that duration, so the host must either poll the ready/busy status or insert a delay between writes. For bulk programming, a page-write mode (the page size is not specified in the brief, but typical parallel EEPROMs of this density use 64-byte pages) reduces the per-byte overhead.","metaTitle":"X28HC64SI-90 64Kbit Parallel EEPROM, 90 ns Access","metaDescription":"X28HC64SI-90 64Kbit (8K x 8) parallel EEPROM, 90 ns access time, industrial temp -40°C to 85°C, 28-SOIC.
