LG-MC2670
CPU : ARM7TDMI microprocessor core
MEMORY : • FLASH Memory : 32M bits (K8D3216UTC-TI07)
• SRAM : 16M bits (K1S161611A-FI70)
CPU
ARM7TDMI 32-bit microprocessor is used and CPU controls all the circuitry. Some of the features of
the ARM microprocessor include a 3 stage pipelined RISC architecture, both 32-bit ARM and 16bit
THUMB instruction setsm, a 32-bit address bus, and a 32-bit internal data bus.
FLASH Memory
Flash Memory is used to store the program of the mobile station. Using the down-loading program,
the program can be changed even after the mobile station is fully assembled.
Pseudo RAM
SDRAM is used to store the internal flag information, call processing data, and timer data.
KEYPAD
For key recognition, key matrix is setup using KEY_SENSE0-4_N signals and GPIO32~36 of output
ports of MSM6000. Backlight circuitry are included in the keypad for easy operation in the dark.
LCD MODULE
LCD module contains a controller which will display the information onto the LCD by 8-bit data from
the MSM.
It has MONO full graphic 120(W) X 64(H) dots
