description
The MPT57216 is a 192-channel color thin-film transistor (TFT) LCD driver based on an active matrix LCD
(AMLCD). It has 3 bits for each RGB input. These 3 bits are decoded internally to select one of eight bias-voltage
levels, V0 to V7 for output, in order to support 512 colors (R = 23 = 8; G = 23 = 8; B = 23 = 8; RGB = 29 = 512).
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

NOTE A. The C32 – C10 inputs are decoded internally to derive SEL0 – SEL7 from the output of a 3-to-8 decoder. Only one of the decoder outputs,
SEL0 – SEL7, puts ≈VEE on the P-CH and ≈VSS on the N-CH of its corresponding transmission gate. This allows only one of eight bias
voltages, V0 – V7, to pass onto OUTn.

FUNCTION
CL

I
Clear input. This active-low clear input resets the clock control circuit, shift register, data memory, and
display latch. CL also sets output to the V0 level. CL must be asserted high for normal operation.
CLK
216
I
Clock input. CLK is the rising edge systems clock for the 64-bit shift register. Also, 9 bits of data are
stored in the data memory by the falling edge of CLK. The clock control circuit stops the internal system clock to save power consumption after 64 clocks.
DSEL
205
I
Data select input. This input inverts the data on C10 to C32 input.
RGB color data input. These nine inputs of 3-bit input data at each of 3 RGB ports selects up to 8-levels of grey scale on the LCD outputs. For Cmn: m = port number and n = weight selected.

Latch Strobe Input. When LS is high, 9 x 64 bits of data memory is latched into the display latch (3 x

be passed on to OUTn using a transmission gate. LS also clears the shift register and clock control
circuit.

Select right/left shift. R/L selects which direction the EIOn enable pulse advances through the 64-bit
shift register. It also selects which direction the 3-bit × 3 RGB data from the data latch is loaded into
three different but adjacent channels of data memory. This data is loaded as the channels are enabled
three at a time by the enable pulse from the shift register. It advances from one output to the next when
shifting through the shift register with each clock pulse.
