Texas Instruments introduced at the 2011 T3 International Conference held on February 25-27 in San Antonio, TX with the TI-Nspire CX and TI-Nspire CX CAS their first graphing calculators with full color, backlit displays.
This TI-Nspire COLOR was one of
the prototypes to test the design in the field.
Dismantling this TI-Nspire COLOR prototype manufactured already in August 2010 in China reveals a very compact design based on only two printed circuit boards (PCB's) with just a few main Integrated Circuits.
Processor: The ARM9 CPU is integrated into an ASIC with the markings ET-NS2010A-0 (T6UJ1XBG-0001), obviously from Toshiba, Japan. The ARM9 core is clocked with 132 MHz compared to the 90 MHz of the previous TI-Nspire.
Please notice that the later TI-Nspire CX and CX CAS use an ASIC
with the markings ET-LC2010B-0 (T6UJ1XBG-0002).
Memory: Both the NAND Flash-ROM with a capacity of 128M Bytes and the SDRAM with a capacity of 16M x 16 Bits are integrated into a Multichip Package (MCP)with the part designation Micron JW378. Using Micron's part number decoder expands the JW378 code to MT29C1G56MAUZAJC-75 and the the the MCP Part Numbering System explains:
|29C: NAND Flash-ROM + LPDRAM
1G: 1G Bits Flash density
56M: 256M Bits LPDRAM density
A: 1.8V Operating Voltage
U: Second generation Flash memory, 128M x 8 Bits
Z: First generation LPDRAM memory, 16M x 16 bits
A: Chip count 1 NAND Flash-ROM, 1 LPDRAM
JC: Package Code
-75: 135 MHz Clock
addition to this impressive Multichip Package we located on the backside of the
PCB an additional Macronix MX29SL402
NOR Flash-ROM with a capacity of 512k
Byte. It is used for the first-stage bootloader ("Boot 1") and was integrated
with the later TI-Nspire CX and CX CAS into the ASIC.
