background: i do macbook repairs and this chip is programmed and is logicboard specific, and its apple's dedicated chip so we don't have any documentation for it, so we cannot buy it or program it.
recently i was looking at atmel's at1284p data sheet and i found that few of its pins are same as at1284p, so i was wondering that is there a way i can read data from it using atmel's or some other kind of programmer.please check the attached photo for pinout information.
What do you mean "the same"? ATmega1284p is not available in BGA package and this chip clearly is a BGA chip.
And if you are talking about pin names like TDI, TDO, TCK, then there are thousands of chips with those pins, it is just a standard JTAG port.
And if it is an Apple chip, you can rest assured there is no way to read it.
And also SWDIO/SWCLK suggest that it is likely to be an ARM Cortex device. I would guess some NXP device.

thanks, i was hoping there maybe some way to get around it, but i guess there is none

LM4FSXAH5BB is LM4F Stellaris MCU from Texas Instruments in BGA157. It is customer specific IC, Stellaris docs and tools may apply for most functions, but not all.
