Microchip Technology Doubles the Flash and RAM of Its LCD PIC18 Microcontrollers, Lowers the Cost.


PIC18F85J90 Microcontroller Series Provides Integrated LCD Module, 32 Kbytes Flash and Internal Voltage Controller for Cost-Sensitive Embedded Display Applications

), a leading provider of microcontroller and analog semiconductors, today announced six new members of the 8-bit PIC([R]) microcontroller family with an integrated Liquid-Crystal Display (LCD) module. The PIC18F85J90 series doubles the amount of Flash and RAM memory over existing 64- and 80-pin family members for cost-effective human-interface applications requiring embedded control, including thermostats, utility meters and medical instrumentation. This increased amount of memory enables users to add more complex functionality, such as speech playback and larger amounts of self-programming memory allocation Reserving memory for specific purposes. Operating systems and applications generally reserve fixed amounts of memory at startup and allocate more when the processing requires it. If there is not enough free memory to load the core kernel of an application, it cannot be launched. , while taking advantage of the cost savings offered by the PIC18 "J" series' 3-volt manufacturing process technology.

The LCD module onboard the PIC18F85J90 series also enables a software-programmable contrast controller. This contrast controller can boost the LCD voltage, dim the display, or compensate for environmental elements like temperature and lighting. These features lower the cost of the LCD glass while improving the display appearance, making advanced LCD functionality affordable to a whole new class of embedded display applications. Other key features include an internal oscillator oscillator

Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air
, improved low-voltage performance and more LCD segments on 64-pin devices, which all help to lower the total system cost.

"Microchip's Flash LCD microcontrollers offer the greatest breadth of LCD segment drivers, package sizes, and integrated features for embedded control applications," said Mitch Obolsky, vice president of the Advanced Microcontroller Architecture Division. "With the PIC18F85J90's high performance, flexible LCD controller and attractive pricing, engineers are now able to add complex functionality, such as speech playback and LCD contrast dimming, to products that previously could not justify the cost."

Example applications for the new PIC18F85J90 microcontroller family with integrated LCD module include: automotive (dashboard displays); instrumentation/measurement (medical instruments/monitors, meter reading, handheld terminal/remote reading); appliance (display/control units on stoves/ovens, microwaves, etc.); industrial (payment systems, water/gas/electric/heat utility meters, gasoline pumps); consumer (programmable thermostats/controls, irrigation irrigation, in agriculture, artificial watering of the land. Although used chiefly in regions with annual rainfall of less than 20 in. (51 cm), it is also used in wetter areas to grow certain crops, e.g., rice.  control, home security systems, exercise equipment); communications (handset displays).

Additional features include:

* 8 to 32 Kbytes of self-programming Flash program memory, and up to 2 Kbytes of SRAM See static RAM.

SRAM - static random-access memory
 

* Enhanced LCD module with four multiplex commons and up to 48 segments driving up to 192 pixels

* Seven power-managed states, and a 32 kHz to 8 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc.  internal oscillator

* High core performance of up to 40 MHz at 3V

* 10-bit analog-to-digital converter with up to 12 signal channels and 100k samples-per-second

* Two analog comparators, internal voltage reference A voltage reference is an electronic device (circuit or component) that produces a fixed (constant) voltage irrespective of the loading on the device, power supply variation and temperature. , brownout A lowering of AC power voltage for some period of time. Brownouts can be very harmful to electronic equipment if sustained for long periods. Brownouts can cause flickering or a dimming on screen, and the computer may experience intermittent problems as a result. See blackout.  detect and low-voltage detect
