Small controller reachs Microchip of emulation semiconductor supplier, in its series of 8 PIC small controller joins 6 fresh blood, introduce video of body of compositive liquid crystal (LCD) module. Of PIC18F85J90 series shine put reach RAM to remember a capacity, more existing 64 reach parts of an apparatus of 80 pin series to increase one times, apply to application of interface of human body of type pilot tall cost effectiveness is embedded inside need, include constant temperature implement, public appearance and medical treatment instrument. Remember the addition of the capacity, the person that let use can add more complex function, for example speech is answered put reach allocate more in great quantities from process designing memory, the technique making Cheng that adopts 3VPIC18J set at the same time saves cost.
Brand-new PIC18F85J90 series is set board on LCD module, can support controller of contrast of software process designing. This contrast controller can promote LCD voltage, adjust display luminance, or make compensation to if temperature reachs light,waiting for environmental element. These functions reduce LCD glass effectively piece cost, improve monitor outward appearance at the same time. Right brand-new inside embed type to show application for, advanced LCD function becomes more substantial consequently. Main function includes other in-house oscillator and more perfect low-pressure character, set more LCD section on 64 pin parts of an apparatus at the same time, reduce integral system cost effectively thereby.
The application of the set of PIC18F85J90 small controller that provides compositive LCD module includes: Car () of instrument board monitor; Appearance / measure (medical treatment instrument / reading of monitor, appearance, portable terminal / Yao is apart from reading) ; Home appliance equipment (boil feed furnace / the indication that 焗 furnace reachs microwave oven to wait / control equipment) ; Industry (pay system, water / gas / electric power / ) of pump of hot public appearance, gasoline; Consumptive sex (but process designing constant temperature implement / control, water equipment of system of security personnel of control, household, exercise) reach communication () of portable phone monitor.
Other function
8 show program memory quickly from process designing to 32Kbyte, reach the static RAM that is as high as 2Kbyte (SRAM)
Stock of aggrandizement LCD module shares multiplex 4 times, reach reach 48 section, drive is as high as 192 to resemble element
7 kinds of power run state, reach a 32kHz to come 8MHz in-house oscillator
The implementation below 3V is as high as the tall core function of 40MHz
