8-bit PIC Microcontrollers

MicrochipTechnology Inc. is expanding its 8-bit segmented LCDmicrocontroller (MCU) family with five new devices-the PIC16LF1902/3/4/6/7 (PIC16LF190X) MCUs. The PIC16LF190Xfamily supports many general-purpose applications and enables theimplementation of LCD into low-power and cost-sensitive designs, such assecurity 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, anda typical active current of 35 microamperes per MHz, the MCUs extend batterylife, while maintaining accurate timing with a RTC and driving a segmented LCD.

The PIC16LF190X includes up to 14 KByte of Flashprogram memory, up to 512 Bytes of RAM, up to 14 10-bit Analog-to-DigitalConverter (A dc) channels, serial communication, temperature indicator and thecapability to drive up to 116 LCD segments.With the addition of XLP technologyfor extended battery life, and capabilities such as utilizing the integratedtemperature indicator to provide crystal-accuracy compensation, low-power RTCsupport and low voltage-detect support utilizing the internal A dc and voltagereference, the MCUs enable low-cost LCD solutions for portable devices.

The PIC16LF190XMCUs are supported by the F1 Evaluation Kit (part # DM164132,$69.99) and Platform (part # DM164130-1,$39.99), as well as the PICkitTM 3 In-Circuit Debugger (part # PG164130,$44.95). The PIC16LF1902,PIC16LF1903 and PIC16LF1906 MCUs are all available in 28-pinSPDIP, SOIC, SSOP and 4 x 4 mm UQFN and die packages. The PIC16LF1904and PIC16LF1907 MCUs are available in 40-pin PDIP, 5 x 5 mm UQFN and diepackages, as well as a 44-pin TQFP. Pricing starts at $0.75 each, in10,000-unit quantities.
