PIC16F1614-I/SL - 8-Bit 32MHz MCU 7KB Flash | Microchip
The Microchip Technology PIC16F1614-I/SL is an 8-bit PIC® XLP™ flash microcontroller featuring a 32MHz CPU, 7KB (4K x 14) program flash, 512 bytes SRAM, and a 14-pin SOIC package. It integrates a 10-bit ADC, Configurable Logic Cell (CLC), Complementary Output Generator (COG), Signal Measurement Timer (SMT), Zero-Cross Detect (ZCD), and CCP peripherals designed for embedded control of small motors and general-purpose applications.
An 8-bit flash microcontroller (MCU) is a small, self-contained computer-on-a-chip that integrates an 8-bit CPU, non-volatile flash program memory, volatile SRAM, and a configurable peripheral set into a single IC. Within the broader hierarchy, 8-bit MCUs sit below 16-bit and 32-bit MCUs in computational throughput, but excel in deterministic real-time control, ultra-low power operation (the PIC16 XLP family is engineered for nanoWatt standby currents), and BOM cost minimization. They are the dominant choice for sensor nodes, motor control loops, user-interface handling, and battery-powered devices where code density and predictability outweigh raw MIPS.
Key features include 32MHz internal oscillator operation, 10-bit ADC with computation, 24-bit Signal Measurement Timer (SMT) for precise time-of-flight and edge counting, Zero-Cross Detect for AC line synchronization, Configurable Logic Cell, Complementary Output Generator, and nanoWatt XLP power management. The 14-pin SOIC (SL) package is a JEDEC-standard 3.90mm-wide surface-mount footprint that is breadboard-friendly and reflow-solderable, suitable for both prototyping and high-volume production.
The PIC16F1614 uses a 14-bit modified Harvard RISC architecture with a 16-level hardware stack, single-cycle hardware multiply, and C-compiler-friendly instruction set. The XLP nanoWatt technology delivers sub-microamp sleep modes enabling multi-year battery life in IoT edge nodes, while the integrated SMT 24-bit timer and CLC permit hardware-level signal processing without CPU intervention, freeing the core for system-level logic.
Typical applications include small DC and stepper motor control (BLDC, brushed DC), fan control, TRIAC dimming with ZCD, sensor signal conditioning, appliance controls, LED lighting drivers, IoT edge nodes, and general-purpose embedded control. The industrial-grade -40C to +85C temperature range supports factory and outdoor deployments.
When designing with this device, allocate sufficient code-space headroom (5-10% free flash for field updates), provide adequate Vdd decoupling per the datasheet reference circuit, and verify that the chosen CCP/COG/SMT peripheral combination fits the application timeline within the 32MHz instruction budget.
