This class of parallel EEPROM is used in embedded systems that require byte- or page-erasable non-volatile storage — firmware parameter tables, calibration constants, configuration maps — where the bus timing must match a legacy microcontroller or FPGA without wait states. ## 120 ns access — bus timing reality The 120 ns access time sets the read cycle window for the parallel bus. A microcontroller or CPLD driving the address and control lines must hold the chip select and output enable active long enough for the data to appear on the bus. ## Drop-in consideration: X28C513EMB-25 The X28C513EMB-25 is a 512 Kbit parallel EEPROM (half the density) with 150 ns access time, same 4.5 V supply, same 32-PLCC footprint, and same 10 ms write cycle. It is not a direct functional replacement — the memory map is 64K x 8 versus 128K x 8 — but for designs that can tolerate half the storage and a slightly slower read, the pinout and bus protocol are compatible. A firmware change to the upper address decode is required.","metaTitle":"Xicor X28C010FM-12 1 Mbit Parallel EEPROM, 120 ns","metaDescription":"Xicor X28C010FM-12 1 Mbit parallel EEPROM, 120 ns access, 4.5 V supply, 128K x 8, 32-PLCC, -55 to 125°C.
