PIC16F887-E/PT 概要
A microcontroller (MCU) is a single-chip computer that contains a CPU, RAM, non-volatile memory (Flash/EEPROM), and peripherals such as timers, ADC, communication ports, and I/O pins on one integrated die. The PIC16F belongs to the mid-range PIC architecture hierarchy, which spans PIC10/12/14/16/18/24/32 families, where PIC16F sits between baseline (PIC10/12/16) and enhanced mid-range (PIC18) in terms of instruction set capability and peripheral integration.
Key features include a 14-channel 10-bit ADC, two analog comparators, one Capture/Compare/PWM (CCP) and one Enhanced CCP module, a USART, MSSP (SPI/I2C), and nanoWatt power management for low-power sleep modes. The E suffix denotes the extended temperature range of -40C to +125C.
The PIC16F887 uses a Harvard RISC architecture with only 35 single-word instructions and 200 ns instruction execution at 20 MHz. Self-programmability supports in-application firmware updates, and ICD (In-Circuit Debug) simplifies development with Microchip's MPLAB X IDE and PICkit debuggers.
Typical applications include industrial control systems, sensor interface modules, home appliance controllers, automotive body electronics, and consumer device mainboards where a balance of GPIO count, on-chip peripherals, and Flash-based flexibility is required.
When designing with the PIC16F887, ensure decoupling capacitors are placed near VDD/AVDD pins and that the MCLR pin is pulled high through a resistor per Microchip guidance. Choose this MCU when you need more GPIO and peripheral channels than a PIC16F84/88 can offer, but do not need the larger memory and instruction set of a PIC18F series part.

主な用途
PIC16F887-E/PT の用途: 7 件s: Industrial Control Systems, Home Appliance Controllers, Sensor Interface Modules, Automotive Body Electronics, Consumer Device Mainboards, Educational and Hobby Development, Power Supply Monitoring and Battery Management.
Industrial Control Systems
The PIC16F887-E/PT fits industrial control designs with its 36 I/O pins, 14-channel 10-bit ADC, and extended -40C to +125C temperature grade. Its 14 KB Flash accommodates state-machine-based PLC logic, sensor scanning loops, and Modbus RTU over USART. The nanoWatt sleep modes draw under 1 uA typical, supporting battery-backed remote terminals. The 44-pin TQFP and Microchip MPLAB X toolchain shorten time-to-prototype for industrial sensor hubs.
おすすめ
Home Appliance Controllers
The PIC16F887-E/PT suits washing-machine, dishwasher, microwave, and HVAC control boards that need to drive relays, triacs, and displays while monitoring sensors. The Enhanced CCP module generates precise PWM for motor speed or heating-element control, while the 14-channel ADC reads temperature, water level, and current sensors. With self-programming Flash, manufacturers can ship firmware updates to installed appliances. The 44-pin TQFP footprint is industry-standard for white-goods mainboards.
おすすめ
Sensor Interface Modules
The PIC16F887-E/PT is well matched to multi-sensor data-acquisition front ends: 14 ADC channels handle thermistors, pressure sensors, and potentiometers simultaneously, while the USART and MSSP forward digitized data to a host MCU or wireless module. Its 256-byte EEPROM stores calibration constants non-volatilely. With 20 MHz CPU clock, oversampling and digital filtering are feasible in firmware without external DSP.
おすすめ
Automotive Body Electronics
The PIC16F887-E/PT operates over -40C to +125C and supports automotive body-control modules such as window lifters, mirror adjusters, interior lighting, and seat controllers. Its Enhanced CCP drives PWM-controlled mirror motors, while the MSSP handles LIN slave communication via an external LIN transceiver. With 36 I/O pins and 14 KB Flash, designers can consolidate what previously required multiple smaller MCUs into a single chip.
おすすめ
Consumer Device Mainboards
The PIC16F887-E/PT powers remote controls, toys, small appliances, and consumer accessories that need USB HID, IR transmit/receive, or display driving. The 20 MHz CPU clock supports real-time bit-banging protocols and the Enhanced CCP drives PWM backlight dimming. Self-programmability enables factory-side firmware personalization per SKU. The 44-pin TQFP is easy to assemble with standard SMT lines.
おすすめ
Educational and Hobby Development
The PIC16F887-E/PT is widely adopted in universities and maker projects because it pairs the PIC16F family simplicity with enough Flash for meaningful C-based projects. Microchip's MPLAB X IDE, XC8 compiler, and PICkit debugger ecosystem are free and mature, with the PIC16F887 supported on the PICkit 3 and PICkit 4. The 44-pin TQFP is available on low-cost development boards from suppliers such as MikroElektronika and Olimex.
おすすめ
Power Supply Monitoring and Battery Management
The PIC16F887-E/PT integrates well into SMBus battery monitors, smart-battery packs, and DC rail supervisors. Its 14-channel ADC samples pack voltage, charge current, and per-cell voltages; USART or MSSP communicates with a host charger or gauge IC. The nanoWatt sleep mode drops quiescent current under 1 uA, preserving battery life when the system is idle. The 256-byte EEPROM logs cycle counts and fault history.

設計ノート
Decouple each VDD/VSS pair with a 100 nF ceramic capacitor placed within 3 mm of the IC pins, and add a bulk 10 uF tantalum or aluminum polymer capacitor near the MCU supply input. The PIC16F887 supports 2.0 V to 5.5 V operation, so the regulator should be chosen with output accuracy better than +/-3% to keep ADC VREF errors under 1 LSB at 10-bit resolution. For battery-powered designs, route the MCU to nanoWatt sleep and wake via WDT or external interrupt to minimize quiescent current.
Place the ICSP pins (RB6/PGC, RB7/PGD, MCLR/VPP) on accessible board-edge or test-point pads so that a PICkit 3/4 or ICD 3/4 can program and debug the assembled board without rework. MCLR must be pulled up to VDD through a 10 kohm resistor and decoupled with a 100 nF cap to VSS to suppress in-circuit reset noise. Keep the 44-pin TQFP land pattern on a 0.8 mm pitch and route the crystal traces within a guard ring tied to ground for EMI suppression.
Configuration bits (FOSC, WDTE, PWRTE, BOREN, LVP, etc.) must be set correctly before the first code execution; an incorrect FOSC selection can leave the MCU without a clock and appear dead. Do not leave unused I/O pins floating - configure them as outputs or inputs with weak pull-ups - because floating CMOS inputs can draw mid-rail current and cause noise coupling into adjacent ADC channels. Avoid using the ICSP pins RB6/RB7 as GPIO unless you have a robust in-circuit programming strategy, as doing so can lock out field firmware updates.
When using the 14-channel 10-bit ADC, ensure that analog traces are kept short and routed away from digital switching signals like PWM outputs and the oscillator traces to minimize crosstalk. Add a small RC low-pass filter (10 ohm + 100 nF) on each analog input if the source impedance exceeds 2.5 kohm, otherwise ADC acquisition time may be insufficient and conversions will be inaccurate. Use AVSS as the dedicated analog ground and tie it to digital ground at one point near the MCU.
