HCMS-3967

Agilent HCMS-39x6 and HCMS-39x7 3.3 V High Performance CMOS 5x7 AlphaNumeric Displays Data Sheet HCMS-3906, HCMS-3966, HCMS-3916, HCMS-3976, HCMS-3907, HCMS-3967, HCMS-3917, HCMS-3977 Description The 3.3 V HCMS-39xx family is similar to the 5.0 V HCMS-29xx family, except it operates at a lower operating voltage. Package dimensions and pin outs are exactly the same for both families. The product has been thoroughly characterized and stringent reliability tested to ensure that the product is of high quality. Similar to the 5.0 V platform, this family product is a high performance, easy to use dot matrix display driven by on-board CMOS IC. Each display can be directly interfaced with a microprocessor, thus eliminating the need for cumbersome interface components. The serial IC interface allows higher character count information displays with a minimum of data lines. The easy to read 5x7 pixel format allows the display of upper case, lower case, Katakana, and custom userdefined characters. These displays are stackable in the x- and ydirections, making them ideal for high character count displays.

The Dot Register contents are unaffected by the Reset pin. (logic low = reset; logic high = normal operation). DATA IN (DIN) Serial Data input for Dot or Control Register data. Data is entered on the rising edge of the Clock input. DATA OUT (DOUT) Serial Data output for Dot or Control Register data. This pin is used for cascading multiple displays. CLOCK (CLK) Clock input for writing Dot or Control Register data. When Chip Enable is logic low, data is entered on the rising Clock edge. REGISTER SELECT (RS) Selects Dot Register (RS = logic low) or Control Register (RS = logic high) as the destination for serial data entry. The logic level of RS is latched on the falling edge of the Chip Enable input. CHIP ENABLE (CE) This input must be a logic low to write data to the display. When CE returns to logic high and CLK is logic low, data is latched to either the LED output drivers or a Control Register. OSCILLATOR SELECT Selects either an internal or external display oscillator source. (SEL) (logic low = External Display Oscillator; logic high = Internal Display Oscillator). OSCILLATOR (OSC) Output for the Internal Display Oscillator (SEL = logic high) or input for an External Display Oscillator (SEL = logic low). BLANK (BL) Blanks the display when logic high. May be modulated for brightness control. GNDLED Ground for LED drivers. GNDLOGIC Ground for logic. VLED Positive supply for LED drivers. VLOGIC Positive supply for logic. 8 AC Timing Characteristics over Temperature Range (-40 to +85 °C) Timing Diagram Ref. Number Description Symbol 4.5 V VLOGIC) and when a high current is forced into the input. To prevent input current latch up and ESD damage, unused inputs should be connected to either ground or VLOGIC. Voltages should not be applied to the inputs until VLOGIC has been applied to the display. 20 Appendix C. Oscillator Appendix D. Refresh Circuitry The oscillator provides the internal refresh circuitry with a signal that is used to synchronize the columns and rows. This ensures that the right data is in the dot drivers for that row. This signal can be supplied from either an external source or the internal source. This display driver consists of 20 one-of-eight column decoders and 20 constant current sources, 1 one-of-eight row decoder and eight row sinks, a pulse width modulation control block, a peak current control block, and the circuit to refresh the LEDs. The refresh counters and oscillator are used to synchronize the columns and rows. A display refresh rate of 100 Hz or faster ensures flicker-free operation. Thus, for an external oscillator the frequency should be greater than or equal to 512 x 100 Hz = 51.2 kHz. Operation above 1 MHz without the prescaler or 8 MHz with the prescaler may cause noticeable pixel-to-pixel mismatch. The 160 bits are organized as 20 columns by 8 rows. The IC illuminates the display by sequentially turning ON each of the 8 row-drivers. To refresh the display once takes 512 oscillator cycles. Because there are eight row drivers, each row driver is selected for 64 (512/8) oscillator cycles. Four cycles are used to briefly blank the display before the following row is switched on. Thus, each row is ON for 60 oscillator cycles out of a possible 64. This corresponds to the maximum LED on time. The temperature of the display will also affect the LED brightness as shown in Figure 10. Appendix E. Display Brightness Appendix F. Reference Material Two ways have been shown to control the brightness of this LED display: setting the peak current and setting the duty factor. Both values are set in Control Word 0. To compute the resulting display brightness when both PWM and peak current control are used, simply multiply the two relative brightness factors. For example, if Control Register 0 holds the word 1001101, the peak current is 73% of full scale (BIT D5=L, BIT D 4 = L) and the PWM is set to 60% duty factor (BIT D 3 = H, BIT D2 = H, BIT D1 = L, BIT D0 = H). The resulting brightness is 44% (.73 x .60 = .44) of full scale. The temperature of the display will also affect the LED brightness as shown in Figure 10.
