Motorola Confidential Proprietary

Charger



Works exactly the same as the P2k products



All the FETS are PFETs



Charger FET runs linearly with all chargers, PCAP controls

Gate voltage based on Voltage Sense across Sense Resister



Midrate FET– Allows for connection of the charger to the

phone



Main FET– controls whether battery is connected to the

phone,



OVIC– Threshold is 6.9+/- 0.2V



Fast Rate Charger, OVIC is ON



Charger is in Linear mode passing ~500mA



Midrate FET is ON



Main FET is OFF



When phone is active it pulls all the current from the

charger, and left over will continue to charge the battery.

Motorola Confidential Proprietary

Charger –Cont’d



Midrate Charger , while phone is in standby or Charge

only mode



OVIC is ON



Charger is in linear mode, the amount of current passing

from charger to battery is dependent upon battery voltage



Main FET is OFF



Midrate Charger, While in a call or using camera/pda/or

other high current tasks



OVIC is ON



Midrate is OFF



Charger is in linear mode



Main FET is ON



This particular mode of the charger is not fully implemented

in the SW and the HW engineers are currently working

through the details of what the phone should do under

different load conditions. Follow up material will need to be

completed once these details have been worked out.

Neptune LTE (U800)



RF connection is same as with LCA architecture



PCAP interface is very similar to P2K, uses a SPI to read

and write registers, & variety of port lines to pass data.



Display and Camera are interfaced through the ATI

Graphic Accelerator. Data is passed to the Graphic Accel

through the DMAC of Neptune. Data is passed back to

Neptune through the SPI. All direct control of the camera

and display is handled by ATI part.



Funlights/LCD Backlights driver is controlled via SPI,

same SPI for PCAP & ATI part.



Bluetooth connections is through a UART.



Keypad, is same implementation as on P2K products



CE Bus should behave same as it does for P2K

26 MHz Clock, Y805



This clock is required for Neptune to
come up fully and run at full speed.



Without the presence of this clock the
phone will start to power up and
immediately shut down. No
communication with Neptune will be
available



This clock is also used by TXVR and
must be very clean.

Replacing Neptune or Memory Device



Neptune and Memory are under a shield and possible to

replace, but difficult. If Field service chose to replace

FLASH, IMEI would need to be reprogrammed.



Neptune is a 280 pin bga, difficult to replace, but possible.



There are new Security enhancements that are not fully

implemented yet.

Flip LCD Modules



This display is a color Active Matrix Liquid Crystal Display

(AMLCD) module of glass construction with black pixels

on a white background.



The display consists of 176 (x RGB Stripe) x 220 pixels

with 64K colors.



There are a few different displays from different vendors



Samsung TF, Samsung TMR and Sharp TF



The Samsung TF and Sharp TF will be used on V300 &

V600 (Only on V300 the situational lighting tail will be

cutoff)



The Samsung TMR is a 98% transmissive display that w/o

the LCD backlight the display is completely black.

Camera

On camera: from hardware perspective, if they can open the flip and probe the 20-pin zif

connector on the display module, while the camera is connected verify following:

First place the camera in view finder mode either through UI or using test command and check

following signals:

B+ = 2.775 Vdc on pin 2.

Check input clock from ATI chip on pin 19, Clock freq ~ 13 - 14 MHz

Check output clock to ATI on pin 18. Should be same as input clock

Check control signals logic level. Both PD (pin 12) and RS (pin 13) should be logic low

below ~).7 Vdc

Check on oscilloscope that D0 - D7, data lines (pin 4 - 11), are randomly toggling during

viewfinder

Check periodic synch signals, HS (pin 16) and VS (pin 15) on oscilloscope. They should

have periodic format during viewfinder.

Check I2C lines SDA (pin 14) and SCL (pin 17). When a test command or any command

sent to the camera it goes over this 2-pin bus and make sure that lines are toggling

upon command sent.

If any of the above is too complicated and time consuming then take the camera out place new

camera and see it works.

If that does not work then replace the display module.

If that does not work, then get a new phone!
