DESCRIPTION
The LH5316P00B is a 16M-bit mask-programmable
ROM organized a s 2 ,097,152 × 8 bits (Byte mode) or
1,048,576 × 16 bits (Word mode) that can be selected
by a BYTE input pin. It is fabricated using silicon-gate
CMOS process technology.

NOTE: The D15/A-1 pin becomes LSB address input (A-1)
when the BYTE pin is set to be LOW in byte mode and
data output (D
15
) when set to be HIGH in word mode.
The input state of BYTE pin can not be changed during
operation. The BYTE pin must be set to either GND or VCC.
