Microchip has just announced a new PIC16(L)F170X/171X family of 8-bit CPUs. In fact there are 22 new members of this family: 11 PIC16F170X/171X devices support 5V down to 2.3V, and 11 PIC16LF170X/171X devices support 3.6V down to 1.8V.
The new devices, which are described as "cost-effective, intelligent analog 8-bit MCUs" offer an easy migration from Microchip's popular PIC16(L)F150X/151X MCUs:
The integration of intelligent analog capabilities reduces system BOM cost and board real estate. These devices boast two internal op-amps for signal amplification and conditioning, a 10-bit ADC (that can be fed from multiple analog input channels), 5-bit and 8-bit DACs, high-speed comparators, and a zero cross detect (ZCD) input that can monitor 120V or 220V AC supplies and be used to initiate actions when the supply is crossing the zero-volt value.
Also of interest are three core-independent peripherals that can handle tasks on their own without code or CPU supervision, and which can therefore continue to function even when the CPU is in a low-power sleep mode. The first type of core-independent peripheral is a number of configurable logic cells (CLCs), which can be used to implement primitive logic functions and registers. By combining several CLCs, it's possible to implement a simple state machine.
The second core-independent peripheral is a complementary output generator (COG) that can be used to generate complementary waveforms with blanking/phase control.
The third core-independent peripheral is a numerically controlled oscillator (NCO) that provides precision frequency control with a resolution of 15 Hz.
Another "first" for PIC16 MCUs is support for Microchip's Peripheral Pin Select (PPS), which means any digital peripheral can be mapped to any I/O pin. This provides layout flexibility and allows the routing of PCB traces to minimize EMC effects.
The new family also offers a wide range of package types, pin counts, memory sizes, and features, including 14-, 2-, 28-, and 40/44-pin packages; 3.5 kB to 28 kB Flash; and 156 B to 2 kB RAM. As usual, Microchip continues to offer a wide range of packaging styles, including DIP, SOIC, SSOP, QFN, and TQFP.
The versatile functionality of the PIC16(L)F170X/171X family of 8-bit CPUs -- coupled with their eXtreme Low Power (XLP) features of 35nA sleep current and 30µA/MHz active current -- allows them to address a broad range of applications, including consumer (e.g., smoke detectors, electric razors, battery chargers, power drills, home appliances), medical (e.g., pulse oximeters, wearable exercise monitors, glucose meters, blood-pressure meters), and lighting control (e.g., indoor/outdoor, automotive lighting, portable lighting, specialty lighting).
