PIC16LF1768-E/ML - 32MHz 8-Bit MCU 7KB Flash 20-QFN | Microchip
The Microchip Technology PIC16LF1768-E/ML is an 8-bit PIC microcontroller from the PIC® XLP™ 16F family, delivering 32 MHz CPU performance with 7 KB (4K x 14) of Flash program memory in a 20-pin QFN (4x4 mm) package with exposed thermal pad. It integrates 512 bytes of RAM, a 10-bit DAC, two operational amplifiers, two configurable logic cells (COG), three configurable logic cells (CLC), zero-cross detect (ZCD), two programmable ramp generators (PRG), and 100 mA high-current I/O pins with Peripheral Pin Select (PPS) flexibility. The "LF" prefix indicates low-voltage operation from 1.8V to 3.6V, optimized for battery-powered designs, while the "-E" suffix designates the extended -40°C to +125°C operating temperature range.
An 8-bit PIC microcontroller is a RISC-based Harvard-architecture computing core that integrates a CPU, non-volatile Flash program memory, SRAM data memory, and a rich set of analog and digital peripherals onto a single silicon die. The PIC16F176x family sits within Microchip's enhanced mid-range core (14-bit instruction word) hierarchy, targeting cost-sensitive embedded designs that need intelligent analog integration - meaning that conventional analog ICs (op-amps, comparators, DACs, PWMs) are absorbed into the MCU to reduce board area, BOM cost, and power consumption.
Key features include eXtreme Low Power (XLP) sleep currents in the nanoamp range, two 10/16-bit PWMs with independent time bases, and 12-bit ADC with computation (ADC²) for automated averaging and threshold comparison. The internal 32 MHz oscillator eliminates the need for an external crystal in many designs, and the PPS feature allows digital peripheral signals to be remapped to a wide selection of physical pins at runtime. The device supports I²C, SPI, UART, and LIN master/slave connectivity through firmware-selectable peripherals.
Architecturally, the PIC16LF1768 uses a 14-bit instruction word, eight-level hardware stack, and 49 instruction opcode set, providing deterministic execution that simplifies real-time control loops. The integrated analog peripherals share a common analog MUX, allowing simultaneous operation of op-amps, DAC, and ADC for closed-loop signal conditioning tasks such as SMPS digital compensation or sensor linearization.
Typical applications include LED lighting controllers, white-goods and appliance front panels, battery-powered IoT sensor nodes, low-cost BLDC/PMSM motor control signal-chain preconditioning, and industrial process transmitters. The 100 mA I/O current also enables direct LED drive without external MOSFETs in moderate-power indicator circuits.
When designing with this device, ensure that the PPS configuration is finalized before code lock, as remapping constraints differ from legacy fixed-pin PIC16 devices. The internal 32 MHz oscillator accuracy of ±1% over temperature is typically sufficient for UART communication at standard baud rates, but a crystal may be required for time-critical protocols.
This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes - including real-world caveats around PPS, analog MUX sharing, and XLP sleep-current measurement - that are not consolidated in the manufacturer datasheet alone.
