Ordering number : EN- 5793 CMOS IC LC378000RP Internally Synchronized Silicon Gate 8M (1,048,576word × 8-bit, 524,288-word × 16-bit) Mask ROM Preliminary Overview The LC378000RP is an 8-Mbit mask ROM that can be switched between byte mode, which provides an 8-bit × 1,048,576-word structure, and word mode, which provides a 16-bit × 524,288-word structure. Since this device operates over the wide supply voltage range of 2.6 to 5.5 V and achieves access times (tAA) of 100 ns (at VCC = 4.5 to 5.5 V) and 200 ns (at VCC = 2.6 to 5.5 V), it can be used in a wide range of systems, from 5-V systems requiring high-speed access to 3-V battery operated systems. Package Dimensions unit: mm 3014A-DIP42 [LC378000RP] Features - Supply voltage range: 2.6 to 5.5 V - Access time (tAA): 100 ns (VCC = 4.5 to 5.5 V) (tCA): 110 ns (VCC = 4.5 to 5.5 V) 200 ns (VCC = 2.6 to 5.5 V) - Switchable between 8-bit and 16-bit data path widths Byte mode: 1,048,576 words × 8 bits Word mode: 524,288 words × 16 bits - Operating current drain: 90 mA (maximum) - Standby current: 30 µA (maximum) - Fully static operation (internal synchronization) - Three-state outputs - Package: 42-pin DIP (600 mil) plastic package SANYO: DIP42 SANYO Electric Co.,Ltd.
