TI REF 84PLUSB/TA3: Z80 microprocessor, RAM, USB-Port 
    and supporting logic
Spansion S29AL016D: 2M Bytea Flash ROM
Toshiba T6K04: Single-chip 64*120 pixel display driver

TI-84PlusSE_OPK_LCD.jpg (228266 Byte)A component not easily detected on the printed circuit board (PCB) of the TI-84 Plus Silver Edition is the driver circuit of the LC-Display. It is just a bare chip mounted on a flexible piece of circuit board attached between the display and the main PCB. 

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, its successor CBL 2 and the Calculator-Based Ranger CBR. 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.

Don't miss the TI-84 Plus Silver Edition "Blaze" and "Raspberry Sorbet" limited edition models introduced for the Back-to-School 2008 campaign.
