PIC16F1784-I/P - 8-Bit 32MHz PIC XLP Flash MCU, 40-PDIP | Microchip
Référence : PIC16F1784-I/P ✓ ActifPIC16F1784-I/P Présentation
An 8-bit microcontroller is a complete computing core built around an 8-bit data bus, usually integrating program flash, RAM, EEPROM and analog peripherals on one die. The PIC16F1784-I/P belongs to the PIC16 family, a hierarchy that runs from 8-bit RISC microcontrollers up to general-purpose embedded processors, and it sits at the enhanced mid-range node of that tree. The "XLP" designation identifies Microchip's low-power platform, where the design target is low active and sleep current rather than raw processing throughput.
Key features include a 32 MHz internal oscillator that removes the need for an external crystal in most designs, 200 ns instruction execution, 49 instructions and 16 levels of stack depth for a compact yet capable architecture. Analog capability is unusually strong for this class: a 12-bit ADC with 15 channels, four comparators with programmable references, and 16-bit PWM with dedicated output edges make the part suitable for direct closed-loop control of power converters and lighting.
Technically the device uses an enhanced mid-range PIC core with self-read/write flash, and its three PSMC modules provide digital or analog feedback control of PWM frequency, duty cycle and phase with 16 ns clock resolution, dead-band control and auto-shutdown. A 256-byte EEPROM gives non-volatile storage for calibration and configuration data without consuming flash program space.
Typical applications include industrial sensor and condition-monitoring nodes, LED lighting drivers, battery charging and DC-DC power conversion control, precision analog measurement systems, motor drive interfacing, and cost-sensitive consumer appliance controllers where analog integration reduces external component count.
One key design consideration is analog layout: keep the ADC, comparator and reference pins away from switching and high-current return paths, use a clean ground reference for AVDD, and decouple supply pins close to the package. The 40-pin PDIP also suits prototyping and breadboarding, where through-hole access and socketed debugging are preferred.
This page combines device specifications, a parameter-by-parameter comparison against close family members, drop-in replacement options, and practical design notes so that engineers can qualify the PIC16F1784-I/P for a new design before committing to a footprint.

Applications typiques
PIC16F1784-I/P convient pour 6 applications: Industrial Sensor and Condition-Monitoring Node, DC-DC Converter and Battery Charger Control, LED Lighting Driver and Dimming Controller, Precision Analog Measurement and Data Acquisition, Motor Drive Interface and Position Feedback, Cost-Sensitive Consumer and Appliance Controller.
Industrial Sensor and Condition-Monitoring Node
The PIC16F1784-I/P suits sensor nodes that must digitise several analogue channels locally and survive wide ambient swings. Its 12-bit ADC with 15 channels removes the need for an external converter in most signal-chain designs, while the four comparators provide fast threshold detection for limit alarms without CPU involvement. With 7 KB of flash, 512 bytes of RAM and 256 bytes of EEPROM, the device holds calibration coefficients and sensor offsets in non-volatile memory, and the 32 MHz internal oscillator eliminates the external crystal and its supply current. As an industrial-grade part rated from -40 C to +125 C, it supports both factory and outdoor monitoring installations without derating.

DC-DC Converter and Battery Charger Control
The three PSMC modules make the PIC16F1784-I/P unusually capable for switch-mode power work. Each block provides digital or analog feedback control of PWM frequency, pulse begin and end times, 16-bit period, duty cycle and phase resolution with 16 ns clock resolution, and supports single, complementary, push-pull and three-phase output modes with dead-band control and an 8-bit counter. Dead-band insertion and auto-shutdown with restart protect a synchronous stage during fault conditions, while the dedicated 16-bit PWM module handles timing-critical outputs. The combination lets a single low-cost controller replace a dedicated PWM IC plus supervisory device.
Recommandé
LED Lighting Driver and Dimming Controller
For constant-current LED lighting, the PIC16F1784-I/P provides the timing and analog blocks needed to build a complete driver on one device. The 16-bit PWM module with programmable dead band drives the switching stage with resolution far beyond what human or camera flicker perception requires, while the 12-bit ADC and comparators can close the loop on a sense resistor or a light sensor. PWM-based dimming ratios are set by the timer block, and the PSMC channels can supervise additional channels or coordinate a boost stage. Because the same silicon handles dimming, fault monitoring and communication, lighting modules reduce their external component count noticeably.
Recommandé
Precision Analog Measurement and Data Acquisition
The PIC16F1784-I/P targets compact instrumentation where a 12-bit converter is the right resolution-versus-cost compromise and board area is limited. Fifteen ADC channels plus four comparators mean multiple sensors can be scanned or watched simultaneously, and the comparators can drive an interrupt for fast threshold events without a polling loop. The 512 bytes of RAM is adequate for short acquisition buffers, and the EEPROM holds offset and gain calibration across the product lifetime. With the enhanced mid-range core executing in 200 ns per instruction, averaging and filtering routines complete well inside typical sample intervals.
Recommandé
Motor Drive Interface and Position Feedback
The PIC16F1784-I/P is a sensible fit for supervisory control around a dedicated motor driver IC, handling direction, braking and fault handshaking while a three-phase capable PSMC can supervise an external inverter stage. Four comparators can watch hall sensors or an over-current signal for immediate shutdown, and the dedicated 16-bit PWM module generates the timing reference. Because the comparators operate without CPU intervention, over-current response is not degraded by a busy main loop. For stepper and BLDC positioning tasks, the 200 ns instruction cycle allows closed-loop step calculations and position bookkeeping in firmware.
Recommandé
Cost-Sensitive Consumer and Appliance Controller
In household appliances and small consumer products, the PIC16F1784-I/P consolidates functions that would otherwise need several discrete chips. The 12-bit ADC reads temperature, level or knob position, the comparators handle simple switch inputs, and the timers manage relays, buzzers and motor drive. Serial I2C and SPI connectivity allows a display, sensor or keypad to be attached without extra bus controllers, while the 256 bytes of EEPROM stores user settings and calibration. The XLP low-power heritage keeps standby current manageable in appliances that spend most of their life switched off.

Notes de conception
The 12-bit ADC and the four comparators share analog pins with the digital port functions, so treat the analog inputs as noise-sensitive nets. Route the analog traces away from the switching nodes of any external power stage, keep the analog ground reference tied to the quiet end of the board, and place the analog supply bypass capacitor directly at the AVDD pin rather than at the connector. On a through-hole 40-pin DIP layout this is easy to get wrong because analog and digital pins alternate around the perimeter of the package.
The 32 MHz internal oscillator avoids an external crystal, but it also means supply current depends on the oscillator configuration you select in firmware. For low-power designs, use the lower-frequency internal oscillator settings or an external low-power source during sleep, and confirm the run and sleep currents in the family data sheet against your duty cycle. Provide local decoupling at every supply pin, with the bulk capacitor placed near the power entry and a 100 nF ceramic at each pin, because the ADC reference and comparators react quickly to supply ripple.
Do not assume the pin functions of the 28-pin SOIC and 44-pin TQFP variants carry over to the 40-pin PDIP. The -I/P ordering code is the 40-pin through-hole industrial option, and the ADC, comparator and PSMC outputs occupy different pins than in the smaller packages. Programmable peripheral pin select on this family means a pin can move between digital and analog roles, so freeze the pin configuration early and re-check it after any firmware change that touches the PPS registers.
When using the PSMC blocks for DC-DC or LED driver work, enable the dead-band counter and the auto-shutdown with restart feature rather than relying on firmware polling, so that a fault is handled in hardware. The 16 ns clock resolution gives fine control of pulse edges, but the practical limit is usually the external gate driver and power stage rather than the timer itself. Validate the dead time against the MOSFET or driver propagation delay in the system, not only against the timing diagram.
