8-bit PIC MCUs have integrated LCD control


Microchip Technology Inc. has expanded its 8-bit segmented LCD microcontroller family with five additional devices — the PIC16LF1902/3/4/6/7 (PIC16LF190X) devices.

The PIC16LF190X family supports many general-purpose applications and enables the implementation of LCD into low-power and cost-sensitive designs, such as security tokens, smart cards, medical devices, home appliances, key fobs or any application involving a segmented LCD.

Featuring eXtreme Low Power (XLP) technology for sleep currents down to 20 nA, and a typical active current of 35 microamperes per MHz, the MCUs extend battery life, while maintaining accurate timing with a RTC and driving a segmented LCD.

The PIC16LF190X family provides an optimized feature set, including up to 14 KB of flash program memory, up to 512 Bytes of RAM, up to 14 10-bit analog-to-digital converter channels, serial communication, temperature indicator and the capability to drive up to 116 LCD segments.

An integrated temperature indicator can be used to provide crystal-accuracy compensation, low-power RTC support and low voltage-detect support utilizing the internal ADC and voltage reference.

The PIC16LF190X MCUs are supported by the F1 evaluation kit and platform, as well as the PICkit 3 in-circuit debugger. Designers can also utilize the full suite of MPLAB development tools, including the MPLAB IDE, MPLAB ICD3, REAL ICE in-circuit emulator, and HI-TECH C compiler for PIC10/12/16 MCUs.

The PIC16LF1902, PIC16LF1903 and PIC16LF1906 MCUs are all available in 28-pin SPDIP, SOIC, SSOP and 4 mm x 4 mm UQFN and die packages. The PIC16LF1904 and PIC16LF1907 MCUs are available in 40-pin PDIP, 5 mm x 5 mm UQFN and die packages, as well as a 44-pin TQFP. Pricing starts at $0.75 each, in 10,000-unit quantities.
