Manufacturer:STM Description:The backplane output devices can be disabled by connecting the OSCillator input (pin 36) to VSS . This allows the 28 segment outputs to be synchronized directly to a signal input at the BP terminal (pin 5). In this manner, several slave devices may be cascaded to the backplane output of one master device, or the backplane may be derived from an external source. This allows the use of displays with characters in multiples of four and a single backplane. A slave device represents a load of approximately 200pF (comparable to one additional segment). Thus the limitation of the number of devices that can be slaved to one master device backplane driver is the additional load represented by the larger backplane of displays of more than four digits. A good rule of thumb to observe in order to minimize power consumption is to keep the backplane rise and fall times less than about 5µs. The backplane output driver should handle the backplane to a display of 16 one-half inch characters. It is recommended, if more than four devices are to be slaved together, the backplane signal be derived externally and all the ICM7211AM devices be slaved to it. This external signal should be capable of driving very large capacitive loads with short (1 - 2µs) rise and fall times. The maximum frequency for a backplane signal should be about 150Hz although this may be too fast for optimum display response at lower display temperatures, depending on the display type. |
