Microchip has announced an expansion of its 8-bit segmented LCD microcontroller (MCU) family with five new devices—the PIC16LF1902/3/4/6/7 (PIC16LF190X) MCUs. 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.
The chips are available in 28- and 40-pin PDIP. Other packages include SOIC, SSOP, UQFN and TQFP, and operate over a 1.8-3.6V range featuring nanoWatt XLP Technology. ICSP and debugging can be accomplished via two pins. A 16 MHz internal oscillator and 31 kHz low-power internal oscillator are included, along with 10-bit resolution ADC (up to 11 channels). The 16LF1904/6/7 also provide one EUSART port with auto baud detect.
The Liquid Crystal Display (LCD) driver module generates the timing control to drive a static or multiplexed LCD panel. In the PIC16LF1902/3 device, the module drives the panels of up to four commons and up to 72 total segments. The LCD module also provides control of the LCD pixel data.
