HD66766 Rev.. / 3 November 2 HD66766 (32 x 76-dot Graphics LCD Controller/Driver for 65K Colors) Rev.. November, 2 Description The HD66766, color-graphics LCD controller and driver LSI, displays 32-by-76-dot graphics for 65K STN colors. A 6-bit high-speed bus interface and high-speed RAM write function enable efficient data transfer and high-speed rewriting of data to the graphics RAM. The HD66766 has various functions for reducing the power consumption of a LCD system, such as lowvoltage operation of 2.2 V/min., a step-up circuit to generate a maximum of 2-times the LCD drive voltage from the supplied voltage, and voltage-followers to decrease the direct current flow in the LCD drive bleeder-resistors. Combining these hardware functions with software functions, such as a partial display with low-duty drive and standby and sleep modes, allows precise power control. The HD66766 is suitable for any mid-sized or small portable battery-driven product requiring long-term driving capabilities, such as digital cellular phones supporting a WWW browser, bi-directional pagers, and small PDAs. Features 32RGB x 76-dot graphics display LCD controller/driver for 65K STN colors low voltage drive and flickerless PWM grayscale drive 6-/8-bit high-speed bus interface and Clock Synchronized Serial Interface ( SPI ) High-speed burst-ram write function Writing to a window-ram address area by using a window-address function Bit-operation functions for graphics processing: - Write-data mask function in bit units. - Logical operation in pixel unit and conditional write function.

CS* I MPU Selects the HD66766: Low: HD66766 is selected and can be accessed High: HD66766 is not selected and cannot be accessed Must be fixed at GND level when not in use. RS I MPU Selects the register. Low: Index/status High: Control For a register or a synchronous clock interface, fixed to the Vcc or GND level. E/WR*/SCL I MPU For a 68-system bus interface, serves as an enable signal to activate data read/write operation. For an 8-system bus interface, serves as a write strobe signal and writes data at the low level. For a synchronous clock interface, serves as the synchronous clock signal. RW/RD* I MPU For a 68-system bus interface, serves as a signal to select data read/write operation. Low: Write High: Read For an 8-system bus interface, serves as a read strobe signal and reads data at the low level. For a synchronous clock interface, fixed to the Vcc or GND level. DB/SDI I/O MPU Serves as a 6-bit bi-directional data bus. For an 8-bit bus interface, data transfer uses DB5-DB8; fix unused DB7-DB to the Vcc or GND level. For a clock-synchronous serial interface, serves as the serial data input pin (SDI). The input level is read on the rising edge of the SCL signal. DB/SDO I/O MPU Serves as a 6-bit bi-directional data bus. For an 8-bit bus interface, data transfer uses DB5-DB8; fix unused DB7-DB to the Vcc or GND level.

HD66766 Rev.. / 3 November 2 Block Function Description System Interface The HD66766 has five high-speed system interfaces: an 8-system 6-bit/8-bit bus, a 68-system 6-bit/8- bit bus, and a Clock synchronized serial interface. The IM2- pins select the interface mode. The HD66766 has three 6-bit registers: an index register (IR), a write data register (WDR), and a read data register (RDR). The IR stores index information from the control registers and the GRAM. The WDR temporarily stores data to be written into control registers and the GRAM, and the RDR temporarily stores data read from the GRAM. Data written into the GRAM from the MPU is first written into the WDR and then is automatically written into the GRAM by internal operation. Data is read through the RDR when reading from the GRAM, and the first read data is invalid and the second and the following data are normal. Execution time for instruction excluding oscillation start is -clock cycle and instructions can be written in succession. Table 2 Register Selection (8/6 Parallel Interface) 8-series Bus 68-series Bus WR RD R/W RS Operations Writes indexes into IR Reads internal status Writes into control registers and GRAM through WDR Reads from GRAM through RDR Table 3 Register Selection (Clock synchronized Serial Interface) Start bytes R/W Bit RS Bit Operations Writes indexes into IR Reads internal status Writes into control registers and GRAM through WDR Reads from GRAM through RDR Bit Operation The HD66766 supports the following functions. A write data mask function that selects data into the GRAM in bit units, and a logic operation function that performs logic operations or conditional determination on the display data set in the GRAM and writes into the GRAM. With the 6-bit bus interface, these functions can greatly reduce the processing lord of the MPU graphics software the display data in the GRAM at high speed. For details, see the Graphics Operation Function section. Address Counter (AC) The address counter (AC) assigns address to the GRAM. When an address set instruction is written into the IR, the address information is sent from the IR to the AC. After writing into the GRAM, the AC is automatically incremented by (or decrement by ). After reading from the GRAM, the AC is not updated. 3
HD66766 Rev.. / 3 November 2 Graphics RAM (GRAM) The graphics RAM (GRAM) has twelve bits/pixel and stores the bit-pattern data of 32 x 76 bytes. PWM Grayscale Palette Circuit The grayscale palette generates a PWM signal, which corresponds to specified grayscale level. Any 65K out of the 4K possible colors can be displayed at the same time. Grayscale Control Circuit The grayscale control circuit performs 6-grayscale control with the pulse width modulation (PWM) method for grayscale display for each color. Timing Generator The timing generator generates timing signals for the operation of internal circuits such as the GRAM. The RAM read timing for display and internal operation timing by MPU access is generated separately to avoid interference with one another. Oscillation Circuit (OSC) The HD66766 can provide R-C oscillation simply through the addition of an external oscillation-resistor between the OSC and OSC2 pins. The appropriate oscillation frequency for operating voltage, display size, and frame frequency can be obtained by adjusting the external-resistor value. Clock pulses can also be supplied externally. Since R-C oscillation stops during the standby mode, current consumption can be reduced. Liquid Crystal Display Driver Circuit The liquid crystal display driver circuit consists of 76 common signal drivers (COM to COM76) and 396 segment signal drivers (SEG to SEG396). Display pattern data from GRAM is latched to the 396-bit latch circuit. The latched data then enables the segment signal drivers to generate drive waveform outputs. The common driver outputs one of the VCH, VM or VCL voltage level. The SGS bit can change the shift direction of 396-bit data for the segment. The CMS bit can also change the shift direction for the common by selecting an appropriate direction for the device-mounting configuration. When display is off, or during the standby or sleep mode, all the above common and segment signal drivers output the GND level, halting the display. LCD drive power supply circuit LCD drive power supply circuit generates VCH, VSH, VM and VCL voltage level to drive LCD panel. 4

HD66766 Rev.. / 3 November 2 Instructions Outline The HD66766 uses the 6-bit bus architecture. Before the internal operation of the HD66766 starts, control information is temporarily stored in the registers described below to allow high-speed interfacing with a high-performance microcomputer. The internal operation of the HD66766 is determined by signals sent from the microcomputer. These signals, which include the register selection signal (RS), the read/write signal (R/W), and the data bus signals (DB5 to DB), make up the HD66766 instructions. There are eight categories of instructions that: Specify the index Read the status Control the display Control power management Process the graphics data Set internal GRAM addresses Transfer data to and from the internal GRAM Set grayscale level for the internal grayscale palette table Normally, instructions that write data are used the most. However, an auto-update of internal GRAM addresses after each data write can lighten the microcomputer program load. Because instructions are executed in cycles, they can be written in succession. 7
