HCMS-29xx Series High Performance CMOS 5 x 7 Alphanumeric Displays Data Sheet Description Features The HCMS-29xx series are high performance, easy  to use dot matrix displays driven by on-board CMOS ICs. Each display can be directly inter­faced with a microproces­ sor, thus eliminat­ing the need for cum­ber­some interface compo­nents. The serial IC interface allows higher char­ac­ ter count information displays with a minimum of data lines. A variety of colors, font heights, and character counts gives designers a wide range of prod­uct choices for their specific appli­cations and the easy to read 5 x 7 pixel format allows the display of uppercase, lower case, Kata­kana, and custom user-defined characters. These dis­ plays are stackable in the x- and y- directions, making them ideal for high character count displays. •  Easy to use •  Interfaces directly with microprocessors •  0.15” character height in 4, 8, and 16 (2x8) character packages •  0.20” character height in 4 and 8 character packages •  Rugged X- and Y-stackable package •  Serial input •  Convenient brightness controls •  Wave solderable •  Offered in five colors •  Low power CMOS technology •  TTL compatible Applications •  Telecommunications equipment •  Portable data entry devices •  Computer peripherals •  Medical equipment •  Test equipment •  Business machines •  Avionics •  Industrial controls Device Selection Guide Description 1 x 4 0.15” Character 1 x 8 0.15” Character 2 x 8 0.15” Character 1 x 4 0.20” Character 1 x 8 0.20” Character AlGaAs HCMS- 2905 2915 2925 2965 2975 HER HCMS- 2902 2912 2922 2962 2972 Orange HCMS- 2904 2914 2924 2964 2974 Yellow HCMS- 2901 2911 2921 2961 2971 Green HCMS- 2903 2913 2923 2963 2973 Package Drawing A B C D E ESD WARNING: STANDARD CMOS HANDLING PRECAUTIONS SHOULD BE OBSERVED TO AVOID STATIC DISCHARGE. HCMS-290x 17.78 (0.700) MAX.

Electrical Description Pin Function RESET (RST) Description Sets Control Register bits to logic low. 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 (SEL) Selects either an internal or external display oscillator source. (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.  AC Timing Characteristics Over Temperature Range (-40°C to +85°C) Timing Diagram Ref. Number Description  Symbol 4.5 V < VLOGIC VLOGIC) and when a high current is forced into the input. To prevent input current latchup 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. The average current required by the display can be calculated with Equation 4. The power supply has to be able to supply IPEAK transients and supply ILED(AVG) continuously. The range on VLED allows noise on this supply without sig­nifi­cantly changing the display brightness. VLOGIC and VLED Considerations The display uses two indepen­dent electrical systems. One system is used to power the display’s logic and the other to power the display’s LEDs. These two systems keep the logic supply clean. Separate electrical systems allow the voltage applied to VLED and VLOGIC to be varied independently. Thus, VLED can vary from 0 to 5.5 V without affecting either the Dot or the Control Registers. VLED can be varied between 4.0 to 5.5 V with­out any noticeable variation in light output. However, oper­at­ing VLED below 4.0 V may cause objectionable mismatch between the pixels and is not recommended. Dimming the display by pulse width modulat­ing VLED is also not recommended. VLOGIC can vary from 3.0 to 5.5 V without affecting either the displayed message or the display intensity. However, operation below 4.5 V will change the timing and logic levels and operation below 3 V may cause the Dot and Control Registers to be altered. The logic ground is internally connected to the LED ground by a substrate diode. This diode becomes forward biased and conducts when the logic ground is 0.4 V greater than the LED ground. The LED ground and the logic ground should be connected to a common ground which can withstand the current introduced by the switching LED drivers. When separate ground connections are used, the LED ground can vary from ‑0.3 V to +0.3 V with respect to the logic ground. Voltages below ‑0.3 V can cause all the dots to be ON. Voltage above +0.3 V can cause dimming and dot mismatch. The LED ground for the LED drivers can be routed separately from the logic ground until an appropri­ate ground plane is available. On long interconnections between the display and the host system, voltage drops on the analog ground can be kept from affecting the display logic levels by isolating the two grounds. 15 Appendix C. Oscillator 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. 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. Appendix D. Refresh Circuitry 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. 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. Appendix E. Display Brightness 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 D4 = L) and the PWM is set to 60% duty factor (BIT D3 = 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 5.
