DESCRIPTION
The Mitsubishi M5M23256-XXXP is a 262144-bit mask-
programmable high speed read-only memory.
The M5M23256-XXXP is fabricated by N-channel

package. It is compatible with the M5L27256K and Intel
27256 in read mode.
The XXX in type code is a three-digit decimal humber
assigned by Mitsubishi to identify the customer's specifi-
cation to which the ROM has been programmed.
FEATURES
• 32768 word x 8-bit organization
• Access time . . . . . . . . . . . . . . . . . . . . . 250ns (max)
• Two line control OE, CE
• Low power supply current (led Active .. BOmA (max)
Standby . 30mA (max)
• Single 5V power supply

FUNCTION
Set the CE and OE terminals to the read mode (low level.)
Low level inputs to CE and OE and address signals to
the address inputs (Ao-A14 ) make the data contents of
the designated address location available at the data output
(00 -07 ).
