Changing the 4 AAA-sized
batteries of the TI-Nspire needs the keyboard to be removed. |

The internal
construction of the TI-Nspire makes use of just 2 printed circuit boards
(PCB's), one for the gray-scale LC-Display and power supply and another one for the computing unit. |
|
The frontside of the
PCB's reveal the construction of the 240 * 320 pixel gray-scale LC-Display and the ARM9 based 32-bit RISC processor. |
|
The brain of the
TI-Nspire is actually a System-on-Chip based on the ZEVIO
architecture from LSI Logic. We assume that the 208 pin housing hosts a 90 MHz ARM9 32-bit RISC processor. |

It took some
image processing technologies to reveal the name
plate of the chip.

|
The TI-Nspire uses three
different memory chips, a 256k*16 NOR Flash-ROM, 32M Bytes
NAND Flash-ROM, and 16M*16 SDRAM. The clock frequency of the SoC is 27 MHz. |
