PIC16F193X/194X Microcontrollers Advanced Performance & Integration with Industry Leading Low Power Summary As the demand for sophistication in consumer and embedded products continues to expand, so does the need for 8-bit microcontrollers that can meet the design challenges this creates. This requires microcontrollers that provide increased performance, maximum integration, and the lowest power – the PIC16F193X/194X family does just that. Based on the 8-bit Enhanced Mid-Range core, the PIC16F193X/194X microcontrollers have a total of 49 instructions to optimize program code and data handling, while increasing efficiency and reducing clock cycles. The PIC16F193X/194X provide up to 28 KB of Flash program memory and numerous enhanced capabilities inclusive of; 16 level hardware stack, up to 1 KB data memory, low power 1.8V operation, nanoWatt XLP, 32 MHz internal oscillator, up to 2x SPI/I2C™ & UART, up to 17 channels 10-bit ADC, up to 5 (E)CCP, 2x comparators, integrated mTouch™ and LCD control. The on-chip LCD drive supports up to 184 segments and provides a low-power drive mode for lower power and increased efficiency. In addition, there are up to 5 Pulse Width Modulation (PWM) channels with independent time bases for controlling various motor types, LED’s, and peripherals. “LF” family members feature Microchip’s nanoWatt XLP Technology – for extreme Low Power consumption – enabling designs to achieve world-leading battery lifetime. These new MCUs feature active currents down to 50 μA/MHz and sleep currents down to 60 nA and sets the industry benchmark for low-power and peripheral integration. All of these general-purpose MCUs are well suited for a multitude of applications in the appliance, consumer, industrial and automotive markets, among others.
