Texas Instruments announced on January 27, 2015 a colorful addition to the TI-84 Plus family of graphing calculators - the new TI-84 Plus CE and successor of the TI-84 Plus C Silver Edition introduced just 2 years earlier.

It features full-color capabilities, a high-resolution, back-lit screen, rechargeable batteries and an updated operating system in a housing 30 percent thinner and 30% lighter than the outgoing mode and yet sporting six times the memory and operating at three times the speed.

This TI-84 Plus CE-T was developed for most countries in Europe and sports a "Press-to-Test" mode to delete parts of the Memory and disable Archives.

Comparing this TI-84 Plus CE-T manufactured in May 2015 by Kinpo Electronics, Inc. in the Philippines with its predecessor TI-84 Plus C Silver Edition reveals only few differences. The design sports still 3 chips:

ET 2014-00: eZ80 microprocessor, RAM, USB-Port 
    and supporting logic
Winbond electronics W29GL032C: 4M Byte Flash-ROM
Ilitek I9335: Single-chip 320*240 pixel display driver

The picture on the right gives an enhanced view of the ASIC that clocks the eZ80 microprocessor with 48 MHz and incorporates the RAM, USB-Port and logic.

This TI-84 Plus CE-T manufactured in May 2015 makes use of one Winbond electronics Flash-ROM with 4M Byte capacity.

While the early members of the TI-84 Plus calculator family use AAA-sized alkaline batteries, accommodate the Color versions 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. A USB type wall charger is included with each unit but for classrooms is the TI-84 Plus CE 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 CE-T dropped the serial port known from earlier members of the TI-84 Plus family and doesn't support the ViewScreen panel and the TI-Presenter with the Presentation Link Adapter anymore. The USB interface of the TI-84 Plus CE-T calculator connects directly with the Calculator-Based Ranger CBR 2 introduced in 2004, the Vernier EasyLink and EasyTemp systems.

The TI-SmartView™ CE Emulator Software for the TI-84 Plus CE-T allows educators to project a representation of the calculator’s display to the entire class.

The TI Connect™ CE computer software allows for connectivity between a computer and the TI-84 Plus CE-T to transfer data, update the Operating System (OS), download Calculator Software Applications (Apps), and to edit and load programs to the calculator

The new operating system 5.x of the TI-84 Plus CE-T is based on the OS 4.0 known from the TI-84 Plus C Silver Edition but they are not compatible due to the different microprocessors used.

To reduce theft of school-owned TI-84 Plus CE a "school bus yellow" edition was introduced in 2015. Don't miss the TI-83 Premium CE sold in France.
