The current-sourcing capability of a microproces- sor port is not sufficient to drive any \u2018end-user\u2019 beyond a fluorescent display panel, however, so for indication-LEDs, relays and solenoids, buffer stages incorporating further ICs and\/or transistors are used; they have the additional advantage of protecting the micro from electrical damage; providing \u2018fan-out\u2019 capability; and if required the facility for logic inversion. Relays and solenoids have special require- ments where they may be held in for long periods \u2013 the required <i>pull-in<\/i><i> <\/i>and <i>hold-in <\/i>currents are greatly different, and can be catered for by two separate windings: a heavy, high-current one is momentarily pulsed to pull-in, then a low \u2018hold\u2019 current is maintained through the other. In some custom-designed syscon micros, separate pull and hold output pins are provided. Alternatively an RC charging circuit provides the initial pull pulse. In very energy-conscious portable video systems <i>latching <\/i>relays and solenoids are used, in which a magnetic armature holds the selected position after a single \u2018pull\u2019 pulse in the right direction through the coil.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>SYSCON MICRO INTERFACING The syscon microprocessor is a wholly digital device and deals with all inputs and outputs in binary form.
