Memory modules
The BIG8051 comes with Flash, RAM
and EEPROM memory modules. This
allows the microcontroller to expand its
memory space.
The Flash module lets the microcontrol-
ler to use an additional 8Mbit flash
memory via SPI. To establish connec-
tion between the Flash module and the
microcontroller, switches 1, 3, and 5
(optionally 2, 4, and 6) on the DIP
switch SW10, as well as switch 7 on the
DIP switch SW15 to the ON position.
The RAM module enables the microcon-
troller to use an additional 64Kbit RAM
memory via SPI. To enable this connec-
tion between the module and the micro-
controller, it is necessary to set switches
1,3,5,7 and 8 (optionally 2,4,6) on the
DIP switch SW10 to the ON position.
EEPROM module enables the microcon-
troller to use an additional 1Kbit
EEPROM memory via I2C serial con-
nection. Set switches 3 and 5 (optionally
4 and 6) on the DIP switch SW12 to the
ON position.
