3. Programming Data

(1) Adjust the EPROM programmer to settings for the MBM27C1000.

(2) Load program data from addresses 10000H to 1FFFFH in the EPROM programmer.

OTPROM addresses FF4000H to FFFFFFH of the MB90P663A in operation mode correspond to addresses

14000H to 1FFFFH in EPROM mode.

(3) Set the MB90P663A into the adaptor socket and install the adaptor socket into the EPROM programmer.

Pay attention to the orientation of the device and the adaptor socket at this time.

(4) Programming data to the EPROM.

(5) If data cannot be programmed, try again with a 0.1 µF capacitor connected between VCC and GND and VPP

and GND.

Note: Since Mask ROM products (MB90662A/663A) do not include an EPROM mode, data cannot be read-out

using an EPROM programmer.
