PT16588 1/8, 1/15 DUTY LCD Controller/Driver DESCRIPTION The PT16588 is a controller/driver with 1/8 and 1/15 duty dot matrix LCD display capability. It has 60 segment outputs, 10 common outputs, and 5 dual segment/common outputs, giving a maximum display capability of 12 columns x 2 lines (at 1/15 duty). LED drive outputs, key scanning key source outputs, and key data inputs are also provided, making it ideal for use in a car stereo front panel, etc. FEATURES Dot matrix LCD controller/driver Pictograph display segment drive capability (MAX. 64) LCD driver unit power supply VLCD independently settable (MAX. 10 V) On-chip key scan circuit (8 × 4 matrix) Alphanumeric character and symbol display capability provided by on-chip ROM (5 × 7 dots) 240 characters + 16 user-defined characters Display contents - 1/8 duty: 13 columns × 1 line, 64 pictograph displays, 4 LEDs - 1/15 duty: 12 columns × 2 lines, 60 pictograph displays, 4 LEDs Serial data input/output (SCK, /STB, DATA) On-chip oscillator Reduced power consumption possible using standby mode BLOCK DIAGRAM Tel: 886-66296288‧Fax: 886-29174598‧ http://www.princeton.com.tw‧2F, 233-1, Baociao Rd., Sindian Dist., New Taipei City 23145, Taiwan PT16588 APPLICATION CIRCUITS WITH INTERNAL POWER SUPPLY CIRCUIT, 1/15 DUTY V1.2 2 July 2013 PT16588 WITH EXTERNAL DRIVE CIRCUIT, 1/15 DUTY V1.2 3 July 2013 PT16588 MULTI-CHIP-MODE V1.2 4 July 2013 PT16588 ORDER INFORMATION Valid Part Number PT16588-TQ Package Type 100-Pin TQFP Top Code PT16588-TQ PIN CONFIGURATION V1.2 5 July 2013 PT16588 PIN DESCRIPTION LED GND Pin Name Symbol LED1 to LED4 VSS LCD drive power supply VLC1 to VLC5 I/O O LCD drive voltage Logic power supply VLCD VDD Synchronization SYNC I/O /LCD OFF I Reset /RESET I Key request Key REQ O SCK I LCD off Shift clock Data DATA I/O Strobe /STB I OSCIN I Key data OSCOUT KEY1 to KEY4 O I Segment /key source dual function SEG1/KS1 to SEG8/KS8 O Oscillation Segment Segment /common dual function Common V1.2 SEG9 to SEG60 SEG61/COM14 to SEG85/COM10 COM0 to COM9 O O O 6 Description LED outputs are Nch open-drain GND pin Dot matrix LCD drive power supply. Connect VLC5 to ground when an internal oscillator is used. LCD drive power supply pin Internal logic power supply pin Synchronization signal input/output pin. When 2 or more chips are used, wired-OR connection is made to each chip. A pull-up resistor is also required when one chip is used. When “L”, a forced LCD off operation is performed, and SEGn & COMn output the unselected waveform. Initial state is set when “L”. “H” if there is key data, “L” if there is none. Key data can be read irrespective of the state of this pin. Output is CMOS output. Data shift clock. Data is read on rising edge, and output on falling edge. Performs input of commands, key data, etc., and key data output. Input is performed from the MSB on the rise of the shift clock, and the first 8 bits are recognized as a command. Output is performed from the MSB on the fall of the shift clock. Output is Nch open-drain. Data input is enabled when “H”. Command processing is performed on a fall. Connect oscillator resistor. When an external oscillator is used, input a clock signal to the OSCIN pin and leave OSCOUT pin open.
