PIC16F1619-E/P - 8-bit MCU, 32MHz, 14KB Flash, 20-PDIP | Microchip

The Microchip PIC16F1619-E/P is an 8-bit PIC16 microcontroller with 14KB Flash, 1KB RAM, and a 32 MHz CPU core, housed in a 20-pin PDIP through-hole package. The -E suffix indicates an industrial temperature grade of -40C to +125C, making it suitable for harsh-environment and automotive-adjacent applications. The device is part of the PIC16(L)F161X family that delivers on-chip features targeted at small-motor embedded control and general-purpose applications. A microcontroller (MCU) is a single-chip computer containing a CPU, memory (Flash program memory plus SRAM and EEPROM), and programmable I/O peripherals. Within the broader hierarchy, MCUs sit inside the embedded computing category, alongside microprocessors and DSPs; the PIC16 family is Microchip's mid-range 8-bit family, sitting between the baseline PIC10/PIC12/PIC16F and the high-performance PIC18/PIC24 families. The PIC16F1619 specifically targets applications that need signal-generation or motion-control peripherals (24-bit SMT, Zero-Cross Detect, CCP, Angular Timer) plus a 10-bit ADC, all in a small 14/20-pin footprint. Key features include 14KB (8K x 14) self-programmable Flash program memory, 1KB SRAM, and on-chip peripherals such as a 10-bit ADC with Computation (ADC2), Capture/Compare/PWM (CCP), 24-bit Signal Measurement Timer (SMT), Zero-Cross Detect (ZCD), and the Peripheral Pin Select (PPS) module. The device supports up to 32 MHz internal oscillator operation, and the XLP (eXtreme Low Power) variant is qualified for Functional Safety (FuSa) applications per the PIC16F16XX family roadmap. The wide 1.8V-5.5V VDD range simplifies designs that must run from a single Li-ion cell, two AA cells, or a regulated 3.3V/5V rail. The PIC16F1619 uses a 14-bit instruction word modified Harvard architecture with separate program and data buses, allowing simultaneous instruction fetch and operand access. The 32 MHz internal oscillator (8 MHz x 4 PLL) is factory-trimmed to within +/-1% across the industrial temperature range, which is sufficient for UART baud-rate accuracy without an external crystal in most cases. The PPS module is a key architectural feature that allows most digital peripherals to be routed to nearly any I/O pin, simplifying PCB layout and BOM reuse across the family. Typical applications include BLDC/PMSM small-motor control (with the 24-bit SMT for back-EMF sensing), LED lighting control, switched-mode power supply (SMPS) control loops, fan and pump controllers, AC line zero-cross detection for triac/SCR dimming, and general-purpose sensor-interface nodes. The wide operating voltage and low-power XLP modes also make it a strong fit for battery-powered IoT edge nodes. When designing with this device, pay attention to the in-circuit serial programming (ICSP) pins (ICSPCLK/ICSPDAT) which must be accessible on the PCB for production programming and debug. Decouple VDD with a 100nF ceramic capacitor placed within 5 mm of the pin, and add a bulk capacitor (>= 1 uF) if the application drives heavy loads. The MCLR pin requires a 10 kohm pull-up to VDD; do not leave it floating, even in production.

PIC16F1703T-I/ST - 8-bit 32MHz 3.5KB Flash MCU 14-TSSOP | Microchip
PIC16F1703T-I/ST

PIC16F1703T-I/ST - 8-bit 32MHz 3.5KB Flash MCU 14-TSSOP | Microchip

The Microchip Technology PIC16F1703T-I/ST is an 8-bit PIC16F microcontroller featuring 3.5KB (2K x 14) of Flash program memory, 256 bytes of RAM, and a 10-bit ADC, all integrated into a 14-pin TSSOP package with a 32MHz maximum operating frequency. The device targets general-purpose low-power embedded designs and ships in tape-and-reel packaging for high-volume SMT assembly. What is a PIC16F microcontroller? The PIC16F family is Microchip's enhanced mid-range 8-bit MCU line built on a RISC architecture, optimized for low power consumption through the XLP (eXtreme Low Power) technology umbrella. MCUs in this class typically integrate Flash program memory, SRAM, on-chip peripherals (ADC, comparators, timers), and communications modules (I2C/SPI/EUSART) onto a single die, serving the power-management, sensor-interface, and consumer-appliance markets that do not require 32-bit performance. Key features of the PIC16F1703 include on-chip operational amplifiers (Op Amps), Core Independent Peripherals such as the Configurable Logic Cell (CLC) and Zero Cross Detect (ZCD), and Peripheral Pin Select (PPS) for flexible signal routing. The 10-bit ADC with computation support accelerates sensor signal conditioning, while the integrated op-amps reduce external analog component count. PPS allows digital peripheral I/O to be remapped to a wide range of physical pins, simplifying PCB layout when board constraints shift late in design. Architecturally, the PIC16F1703 uses a Harvard RISC core with a 14-bit instruction word, a single-cycle instruction execution at 32MHz (200ns instruction time), and hardware stack support. The on-chip voltage regulator allows direct operation from 1.8V to 5.5V supplies, making the device compatible with both 3.3V and 5V system rails. XLP technology enables nanoWatt sleep modes with sub-µA current consumption, extending battery life in IoT and remote-sensor nodes. Typical applications include LED lighting controllers, battery-powered sensor nodes, small appliance control boards, smoke and CO detectors, and general-purpose logic-replacement modules. The combination of integrated op-amps and a 10-bit ADC makes it well-suited for closed-loop analog control, while PPS and CLC support discrete glue-logic replacement. The 14-TSSOP footprint is among the smallest standard MCU packages, enabling compact PCB designs. When designing with this device, ensure adequate decoupling on VDD (a 0.1µF ceramic plus a bulk cap) and place the ICSP/ICD pins on accessible header pads for in-circuit programming and debugging. Confirm that the chosen clock configuration (HFINTOSC vs external crystal) meets the timing accuracy required by the application. Review the device's electrical characteristics section for I/O pin loading rules when driving LEDs or relays directly from GPIO.

PIC16F1704-E/ML - 8-bit MCU, 7KB Flash, 32MHz, 16-QFN | Microchip

The Microchip Technology PIC16F1704-E/ML is an 8-bit PIC16F microcontroller featuring 7KB (4K x 14) of Flash program memory and 512 bytes of RAM, running at up to 32 MHz, and packaged in a 16-pin QFN (4x4 mm) with exposed thermal pad. It integrates on-chip op amps, a 10-bit ADC, an 8-bit DAC, high-speed comparator, CCP/PWM, complementary output generator (COG), Zero Cross Detect (ZCD), Configurable Logic Cell (CLC), and Peripheral Pin Select (PPS), consolidating what would otherwise be a multi-chip analog/digital signal chain onto a single MCU. The PIC16F1704 belongs to the PIC16F170X/171X family of PIC microcontrollers targeted at cost-sensitive mixed-signal designs. An 8-bit microcontroller (MCU) is a small, self-contained computing device built around an 8-bit data path, an ALU, on-chip program memory, RAM, and a rich set of peripherals. PIC microcontrollers from Microchip use a RISC-style modified Harvard architecture with Flash program memory and are widely adopted in embedded systems spanning consumer, industrial, and automotive applications. Within the broader taxonomy, PIC16F MCUs sit between smaller PIC10/PIC12 devices and larger PIC18/PIC24 families, offering a balance of footprint, cost, and peripheral integration. Key features of the PIC16F1704-E/ML include eXtreme Low Power (XLP) technology for battery-friendly sleep currents, Peripheral Pin Select (PPS) for flexible signal routing, core-independent peripherals (CLC, COG, ZCD) that offload timing-critical tasks from the core, and a high-speed comparator with DAC reference. The combination of op amps, DAC, and 10-bit ADC makes the part a strong fit for sensor conditioning and closed-loop control applications. The 32 MHz internal oscillator provides 8 MIPS of computational throughput. From an architecture perspective, the PIC16F1704 uses a 14-bit instruction word optimized for compiled C code density, with hardware stack and interrupt controller supporting prioritized events. The PPS module allows most digital peripherals to be remapped to multiple I/O pins, simplifying PCB layout. The 16-QFN package exposes a thermal pad, allowing dissipation of up to 800 mW in properly designed layouts. Typical applications include LED lighting control (constant-current drivers using COG/PWM), TRIAC-based AC switching (using ZCD), battery-powered sensor nodes (leveraging XLP), fan and small motor control (with CCP/PWM + comparator), and consumer appliance user interfaces. For designers who need more memory or additional I/O, Microchip offers the PIC16F1705, PIC16F1708, and PIC16F1709 in compatible footprints.
