The screen that you proposes sounds OK.

16 data lines.

RS, WR, RD for control the screen.
RESET for the reset.
BLCNT for the back light.
TP_SI, TP_SO, TP_IRQ, TP_SCK for control the touch pad.

It is 16 data lines, 3 control lines, plus RESET and BLCNT. 21 lines for control the screen.

It is 4 lines for control the touch pad.

A total amount of 25 lines for control the touch screen and 3.3v that allows to connect directly to the microcontroller.
