reduce theft of this new school-owned TI-Nspire CX
calculator, Texas Instruments introduced on February 25, 2011 the
TI-Nspire CX EZ-Spot
Teacher Packs with a bright, easy-to-spot, "school bus yellow" design.
Texas Instruments changed in Fall 2014 the internal construction of the TI-Nspire CX calculators and we noticed Li-ion batteries with a larger capacity of 1,200 mAh compared to the original 1,060 mAh specification. The batteries are interchangeable with the TI-84 Plus CE.
Dismantling this TI-Nspire CX EZ-Spot manufactured in December 2014 by Inventec Corporation in its Pudong Campus in Shanghai, China reveals a very compact design based on just 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-LC2010B-0 (T6UJ1XBG-0002), obviously from Toshiba, Japan. The ARM9 core is clocked with 132 MHz compared to the 90 MHz of the previous TI-Nspire.
Memory: Both the NAND Flash-ROM and the SDRAM are integrated into a Multichip Package with the part designation ESMT (Elite Semiconductor Memory Technology Inc., Taiwan) FM60D1G12A-6BE. Deciphering the part number reveals the capacity of the Flash-ROM (128 MByte) and SDRAM (64 MByte):
|• Product Family 60 NAND(x8) + Mobile SDRAM(x16)
• Operating Voltage D = 1.8V NAND, 1.8V DRAM
• Flash Density 1G = 1 Gbit NAND Flash-ROM
• RAM Density 12 = 512 Mbit SDRAM
• Major Version A
• RAM Speed 6 = 166MHz
• Package Code B = BGA107
• Working Temperature E = -25°C to 85°C
• TI-Nspire CX EZ-Spot
