Technical Section

All functional blocks of the system module are mounted on a single multi layer printed circuit board. The chassis of the radio unit has separating walls for baseband and RF. All components of the baseband section are surface mount-able. They are soldered using reflow. The connections to accessories are taken through the bottom connector of the radio unit. The connections to the User Interface module (UIF) are fed through a flex connector. There is no physical connector between the RF and...

Block Description of CTRLU

The MCU has a 20 bits wide address bus A 19 0 and an 8 bit data bus with memories. The address bits A 19 16 are used for chip select decoding. The decoding is done in the D2CA ASIC. The ASIC can address two 4 Mbit or smaller or one 8 Mbit flash memories. Hitachi HD647536 processor has internal ROM and RAM memories. One wait state is used with external memory access. On the Hitachi HD647536 internal memory map there is the follow- 2 Mbit Flash, paged by ASIC page bit to 4 Mbit Technical...
