Stresses above the given values will cause permanent damage to the device. 2. Parameters are valid over the operating temperature range unless otherwise specified. 3. All voltages are with respect to VSS unless otherwise specified. 4. The storage temperature specifies a safe temperature range for the chip when not powered. 7 HANDLING Inputs and outputs are protected against electrostatic discharge in normal handling. However it is good practice to take normal precautions appropriate to handling MOS devices (see “Handling MOS devices” ). 2004 Aug 10 6 Philips Semiconductors Objective specification 132 × 132 RGB single chip TFT driver with DC-to-DC converter 8 PCF8881 APPLICATION INFORMATION logic LOW logic LOW logic LOW 1.8 V logic HIGH WR_N D [0] /SDA D [2 ] D [4 ] D [6 ] MPU CS_N RES_N D [7 ] D [5 ] D [3 ] D [1 ] DCX/SCL RD_N 0V 2.7 V INDUCTIVE DC-TO-DC CONVERTER IREF VBG VDDD [MODE] SCAN_MODE [1] VSSD [MODE] SCAN_MODE [0] VDDD [MODE] ISEL[2] VSSD [MODE] ISEL [1] FRM_MODE T [6:4] T [3:1] OSC VDDD ISEL[0] WR_N D [0] /SDA D [2] G131 to G0 D [4] D [6] D [8] 132 row drivers D [10] D [12] D [14] PCF8881 CS_N TE VCOM RES_N D [15] D [13] D [11] S395 to S0 D [9] D [7] 396 column drivers D [5] D [3] D [1] DCX/SCL RD_N VSSD VSSA VDDA SWCTRLP SWCTRLN VGL_OUT VGL_IN VSN_OUT VSN_IN VSP_OUT VSP_IN VGH_OUT VGH_IN LCD panel 001aaa304 Leave all remaining pads open circuit.
