To
reduce theft of this new school-owned TI-Nspire CX
calculator, Texas Instruments introduced on February 25, 2011 the EZ-Spot
Teacher Packs with a bright, easy-to-spot, "school bus yellow" design.
The design was later changed, don't miss the second edition of the
TI-Nspire CX EZ-Spot.
Dismantling
this TI-Nspire CX EZ-Spot manufactured in June 2011 by
Inventec Corporation in its
Pudong Campus in Shanghai, China reveals a
very compact design based on just two printed circuit boards (PCBs) with just a
few main Integrated Circuits. The Date code
P-0611C of the featured TI-Nspire CX EZ-Spot refers to Revision C, also known as
Firebird Color or original design. Texas Instruments introduced in March 2013 with Revision J the first major redesign of the TI-Nspire CX, known as NSC CR and in April 2014 with Revision O the second redesign known as NSC CR II, followed in October 2014 with Revision T, known as
NSC CR III. Texas Instruments changed in November 2015 the design of the hardware completely and Revision W, known as
NSC CR IV, consolidated all electronics of the TI-Nspire onto one PCB.
Processor:
The ARM9 CPU is integrated into an ASIC with the markings ET-NS2010B-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. Learn more about the Hardware Architecture of TIs Graphing Calculators.
Memory:
Both the NAND Flash-ROM and the SDRAM with are integrated into a Multichip Package with the part designation Samsung
K511F12ACA-B075. Deciphering the part number reveals the capacity of the
Flash-ROM (128M Bytes) and SDRAM (32M x 16 bits):
| Product Family K5 = Samsung MCP (2 chips) Device Type 1 = NAND Flash Rom + Mobile SDR NAND Flash Density, Organization 1F = 1 Gbit, x8 RAM Density, Organization 12 = 512 Mbit, x16 Operating Voltage A = 1.8V NAND, 1.8V DRAM Flash Block Architecture C = Uniform block Version A = 2nd Generation Package Type B = FBGA NAND Flash Speed 0 = None RAM Speed 75 = 7.5 ns (133MHz@CL3) |
