To
reduce theft of this new school-owned TI-84 Plus C Silver Edition calculator, Texas Instruments introduced in May 2013 the TI-84 Plus C Silver
Edition CX EZ-Spot Teacher Packs with a bright, easy-to-spot, "school bus yellow" design.
Comparing this TI-84 Plus C Silver Edition EZ-Spot manufactured in March 2014 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 Z80
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 March 2013 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 1,200 mAh and a voltage of 3.7 Volt for a typical operating time of 50 hours.
Please notice that earlier prototypes of the
TI-84 Plus C Silver Edition used a battery with a slightly larger
capacity of 1,230 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 C 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.
