The calculator retains the 320x240-pixel color screen, rechargeable battery, and key layout of the TI-84 Plus C Silver Edition, while removing the 2.5 mm I / O ("DBUS") linkport and moving the USB port and charging LED to the right side of the handheld. The calculator's OS 5. x is incompatible with the TI-84 Plus C Silver Edition's hardware. The calculator has 154KB of user-accessible RAM and 3.0 MB of Archive memory. It uses the eZ80 processor from Zilog, making all Z80 assembly programs from previous 84 Plus series calculators incompatible. The CE comes in multiple colors, Classic (black), Silver Linings, Radical Red, True Blue, Denim (navy blue), Lightning (light blue), Plum Pi (purple), Positively Pink (as of March 2015), Golden Ratio, and Bright White (as of June, 2016). Like the rest of the 84 Plus series, it is allowed on most standardized tests. The calculator comes programmed with seven different languages (English, French, German, Portuguese, Spanish, and Swedish). In 2016, the TI-84 Plus CE-T was released for the European educational market. The only significant difference from the CE model is the addition of an LED that blinks while the calculator is in Press-to-Test mode.
