... Character 2975 ESD WARNING: STANDARD CMOS HANDLING PRECAUTIONS SHOULD BE OBSERVED TO AVOID STATIC DISCHARGE. Description 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 microprocessor, thus eliminating the need for cumbersome interface components ...

... Display Overview The HCMS-29xx series is a family of LED displays driven by on-board CMOS ICs. The LEDs are configured font characters and are driven in groups of 4 characters per IC. Each IC consists of a 160-bit shift register (the Dot Register), two 7-bit Control Words, and refresh circuitry ...

... CONTROL REGISTERS NOTE: 1. DATA IS COPIED TO THE CONTROL REGISTER OR THE DOT LATCH AND LED OUTPUTS WHEN CE IS HIGH AND CLK IS LOW. HCMS-29xx Write Cycle Diagram columns by 8 rows. This array can be conceptualized as four dot matrix character locations, but only 7 of the 8 rows have LEDs (see Figures 1 & ...

... These bits must always be pro- grammed to logic low. Cascaded ICs Figure 3 shows how two ICs are connected within an HCMS-29XX display. The first IC controls the four left-most characters and the second IC controls the four 11 right-most characters. The Dot Registers are connected in series to form a 320-bit dot shift register ...

... How- ever, for best results, standard CMOS handling precautions should be used. Before use, the HCMS-29XX should be stored in antistatic tubes or in conductive material. During assembly, a grounded conductive work area should be used and assembly personnel should wear conductive wrist straps ...
