131072.BIT(16384.WORD BY 8.BIT)MASK.PROGRAMMABLE ROM
DESCRIPTION
The Mitsubishi M5M23128-XXXP is a 131072-bit mask-
programmable high speed read-only memory.
The M5M23128-XXXP is fabricated by N-channel
polysilicon gate technology and available in a 28-pin OIL
package. It is interchangeable with the M5L27128K and
Intel 27128 in read mode.
The XXX in type code is a three-digit decimal number
assigned by Mitsubishi to identify the customer's specifi-
cation to which the ROM has been programmed.
FEATURES
• 16384 word x 8-bit organization
• Access time ................ _ .... 250ns (max)
• Two line control OE, CE
• Low power supply current {led Active .. 80mA (max)
Standby . 30mA (max)
• Single 5V power supply
• 3-state output buffer
• Input and output TTL-compatible
• Standard 28-pin OIL package
• Interchangeable with the M5L27128K and Intel 27128
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-A13 ) make the data contents of
the designated address location available at the data output
(00 -07 ),
