BANGALORE, INDIA: Microchip Technology Inc., a provider in microcontroller and analog semiconductors, announced on Wednesday the launch of its PIC18F87J90 8-bit direct LCD-drive microcontrollers (MCUs) with nanoWatt Technology.


The 64- and 80-pin devices extend the memory reach and peripheral set of Microchip's LCD MCU portfolio, said a press release. It features 64 - 128 KB Flash and 4 KB RAM, and 8-bit MCUs to include a Real-Time Clock and Calendar (RTCC), and Charge Time Measurement Unit (CTMU) peripheral for capacitive touch sensing or precise time measurement, it added.

Microchip said the PIC18F87J90 devices are pin compatible with Microchip's PIC18F85J90 devices, providing an easy migration path across Microchip's entire LCD-drive MCU family and simplified application upgrades.

With Microchip's nanoWatt Technology, the MCUs help maintain the system's low-power ratings, and can even drive the display in sleep mode to conserve power, it claimed.


Additionally, the onboard LCD module contains a software-programmable contrast controller that provides display boost or dimming and compensates for environmental elements such as temperature and lighting.

The on-chip hardware RTCC works even in sleep mode to enable real-time tracking and lower power consumption.

"Microchip's PIC18F87J90 MCUs expand our portfolio of cost-effective LCD products. For example, in electrical power meters, the extended memory, RTCC and multiple serial channels deliver a highly cost-effective feature set," said Mitch Obolsky, vice president of Microchip's Advanced Microcontroller Architecture Division.

The micro controllers are designed for cost-sensitive embedded display applications in the consumer, industrial, medical and automotive markets, the release added.
