LC87F2608AUMM-AH ON Semiconductor

Ordering number : ENA2175 LC87F2608A CMOS IC 8K-byte FROM and 512-byte RAM integrated LC87F2608A Minimum Bus Cycle Time (Note1) 100ns (10MHz) V =2.7 to 5.5V (Note2) DD Minimum Instruction Cycle Time 300ns (10MHz) V =2.7 to 5.5V (Note2) DD Note1: The bus cycle time here refers to the ROM read speed. Note2: Use this product in a voltage range of 3.0 to 5.5V because the minimum release voltage (PORRL) of the power-on reset (POR) circuit is 2.87V0.12V.
