2.3.5 Logic Part
The Logic part consists of internal CPU of MSM6000, SRAM, FLASH ROM.
The MSM6000 receives TCXO (19.20MHz) clock signals from X100, and then controls the phone
during the CDMA mode. The major components are as follows:
CPU : ARM7TDMI microprocessor core
MEMORY :
• FLASH ROM : 32Mbits (U202, K8D3216UTC-DI07)
• STATIC RAM : 16Mbits (U203, K6F1616U6C-XF70)
CPU
The 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 16-bit THUMB instruction sets, a 32-bit address bus, and a 32-bit internal data bus. It has a high
performance and low power consumption.
