Texas Instruments announced on January 18, 2013 a colorful addition to the TI-84 Plus family of graphing calculators - the new TI-84 Plus C Silver Edition. It features full-color capabilities, a high-resolution, back-lit screen, rechargeable batteries and an updated operating system.

Comparing this early TI-84 Plus C Silver Edition "MARKETING" manufactured in December 2012 by Kinpo Electronics, Inc. in China with a traditional TI-84 Plus Silver Edition reveals only few differences. The design sports still 3 chips:

TI REF 84PLUSB/TA3: Z80 microprocessor, RAM, USB-Port 
    and supporting logic
Macronix MX29LV320: 4M Bytes Flash ROM
Ilitek ILI9335: Single-chip 320*240 pixel display driver

The picture on the right gives an enhanced view of the ASIC that clocks the Z 80 microprocessor with 15 MHz and incorporates the RAM, USB-Port and logic. Learn more about the Hardware Architecture of TI’s Graphing Calculators.

Recently members of the Graphing Calculator Programming community under the lead of Xavier Andréani made a very interesting discovery.

All TI-84 Plus / S.E. with the TA2 or TA3 ASIC have access to 128k Bytes RAM.
All TI-84 Plus / S.E. with the TA1 ASIC have access to only 48k Bytes RAM using
    the same assembly commands.

This TI-84 Plus C Silver Edition manufactured in December 2012 makes use of one Macronix Flash ROM with 4M Bytes capacity.

While the early members of the TI-84 Plus calculator family use AAA-sized alkaline batteries accommodates the Color version an internal Li-ion battery with a capacity of 1,230 mAh and a voltage of 3.7 Volt for a typical operating time of 50 hours. Please notice that later calculators reduced the capacity of the battery to 1,200 mAh. A USB type wall charger is included with each unit but for classrooms is the TI-84 Plus C Charging Station available. It holds up to 10 calculators and charges them with two small contacts located in the front of the calculator.

The TI-84 Plus Silver Edition supports the ViewScreen panel and the TI-Presenter with an Presentation Link Adapter. A serial port of the calculators allows the connection to the Calculator-Based Laboratory system CBL 2. The added USB interface of the TI-84 Plus family calculators connects directly with the Calculator-Based Ranger CBR 2 introduced in 2004. With a new cradle even the optional full-sized QWERTY Keyboard introduced in 2002 matches with the TI-84 Plus series.

Texas Instruments announced on March 1st, 2010 the TI-84 Plus Operating System version 2.53MP with MathPrint™ mode for free download. The OS 2.53MP enables users to input and view math symbols and formulas, including stacked fractions, in their handhelds exactly as the equations appear in textbooks. The new operating system 4.0 of the TI-84 Plus C Silver Edition is based on the 2.55MP, a minor bug fix of the 2.53MP from January 15, 2011.
