PIC16F886-E/SS - 8-Bit 20MHz MCU, 14KB Flash 28-SSOP | Microchip
MPN: PIC16F886-E/SS ✓ فعالPIC16F886-E/SS نمای کلی
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path CPU, on-chip program memory, data RAM, non-volatile EEPROM, and a mix of analog/digital peripherals. PIC16F microcontrollers sit within Microchip's mid-range 8-bit MCU family (PIC10/12/14/16/18), which belongs to the broader category of microcontrollers (MCUs) and ultimately embedded controllers in the semiconductor product taxonomy. They use a RISC-style Harvard architecture with 35 single-word instructions and a 200 ns instruction cycle at 20 MHz, optimized for deterministic, low-cost control tasks.
Key differentiating features of the PIC16F886 include nanoWatt technology for ultra-low-power sleep modes (down to ~50 nA typical), self-programming support for in-field firmware updates, an ICD (In-Circuit Debugger) interface, an integrated 8 MHz internal oscillator, and wide 2.0 V to 5.5 V operating voltage with automotive AEC-Q100 qualification. The enhanced 14-bit ADC and ECCP module provide finer PWM resolution than the legacy PIC16F87x family.
Technically, the PIC16F886 uses a 14-bit instruction word with separate program and data buses (Harvard architecture). Two 8-bit Timer0/Timer2 plus one 16-bit Timer1 supply flexible timing; the ECCP module adds programmable dead-band delay, auto-shutdown and steering for full-bridge motor or power-converter control. The nanoWatt core offers multiple idle/sleep modes with selective peripheral clock gating, enabling battery-powered designs where average current falls below 1 microamp.
Typical applications include industrial control panels, automotive sensor modules (AEC-Q100 grade), low-power remote sensor nodes, consumer appliance controllers, and small motor/lighting PWM drivers. The 14 KB flash comfortably hosts state-machine plus protocol stacks such as LIN-slave or Modbus RTU.
When designing with the PIC16F886-E/SS, place decoupling capacitors (100 nF plus 10 uF bulk) within 5 mm of VDD/VSS pins, route MCLR through the recommended 10 kohm pull-up with a 100 nF capacitor to ground, and observe SSOP thermal limits (theta_JA ~ 95 C/W) when driving continuous loads on multiple I/Os.

کاربردهای معمول
PIC16F886-E/SS مناسب است برای 6 کاربردs: Automotive Sensor Modules (AEC-Q100), Low-Power Remote Sensor Nodes, Industrial Control Panels, Consumer Appliance Controllers, Lighting and LED PWM Drivers, Small Motor / Fan PWM Controllers.
Automotive Sensor Modules (AEC-Q100)
The PIC16F886-E/SS fits automotive sensor modules thanks to its AEC-Q100 qualification, 2.0-5.5 V supply range and extended -40 C to +125 C operating temperature. The 11-channel 10-bit ADC directly reads automotive sensors such as temperature, pressure and position, while the enhanced 10-bit ADC and ECCP modules drive H-bridge or proportional-valve actuators. With nanoWatt sleep currents under 1 microamp, the part can be permanently powered from the battery in BCM and sensor-node applications, waking only on CAN/LIN activity or periodic ADC scans.

Low-Power Remote Sensor Nodes
The PIC16F886-E/SS is a strong fit for battery-powered remote sensor nodes such as wireless thermostats, utility meters and agricultural sensors. Its nanoWatt technology supports sleep currents down to ~50 nA typical, and the integrated 8 MHz internal oscillator eliminates an external crystal for BOM savings. The USART plus MSSP (SPI or I2C) interfaces connect to RF transceivers such as Sub-GHz modules and to I2C environmental sensors (temperature/humidity). The 14 KB Flash comfortably hosts state-machine firmware plus Modbus or LIN-slave stacks.

Industrial Control Panels
For industrial HMI and control panels, the PIC16F886-E/SS offers 25 digital I/O lines plus an 11-channel ADC that reads key-panel buttons, rotary encoders, current shunts and 4-20 mA loops. The ECCP module with programmable dead-band delay and auto-shutdown is ideal for driving triac-gated heater or motor loads, while the USART enables RS-485 Modbus RTU master/slave communication. The 28-SSOP package suits compact panel PCBs, and the 5.5 V VDD tolerance simplifies 24-V system rails with a small linear regulator.
پیشنهادی
Consumer Appliance Controllers
The PIC16F886-E/SS suits cost-sensitive consumer appliances such as coffee machines, microwave ovens, washing machines and small HVAC indoor units. Its 14 KB Flash and 256 bytes EEPROM store user settings, while the ECCP module drives TRIAC-gated heater elements or BLDC fan motors. With nanoWatt sleep current and the wide 2.0-5.5 V supply, the same hardware can run from a 3.3 V or 5 V rail without redesign, keeping BOM costs low in high-volume products.
پیشنهادی
Lighting and LED PWM Drivers
The PIC16F886-E/SS drives multi-channel LED strings via its ECCP and standard CCP PWM modules. With 20 MHz CPU and 10-bit PWM resolution at reasonable PWM frequencies, the MCU produces smooth dimming curves and color-mixing sequences for architectural lighting and RGB strips. The 11-channel ADC reads ambient light sensors and potentiometer dimmers, while the USART or MSSP links to DMX-512 receiver chips or addressable LED drivers such as WS2812 cascades.
پیشنهادی
Small Motor / Fan PWM Controllers
The PIC16F886-E/SS is well-suited to small BLDC and brushed-DC motor controllers, including CPU fans, small pumps and valve actuators. The enhanced ECCP module supports full-bridge PWM with programmable dead-band delay and auto-shutdown on overcurrent, while the 11-channel ADC reads back-EMF, current-sense amplifiers and tachometer inputs. The integrated 8 MHz oscillator and 2.0-5.5 V VDD simplify 3.3 V and 5 V motor-board designs.

یادداشت‌های طراحی
Place a 100 nF decoupling capacitor within 5 mm of each VDD/VSS pair (pins 8/19 and 20/27) plus a single 10 uF bulk capacitor near the MCU supply pin. For battery applications, the PIC16F886's nanoWatt sleep modes drop current to ~50 nA typical when the watchdog, ADC and oscillators are disabled. Use the internal 8 MHz oscillator with the INTOSC configuration bit rather than an external crystal to save quiescent current and BOM cost.
Keep the MCLR pin (pin 1) pull-up at 10 kohm and connect a 100 nF capacitor between MCLR and ground within 5 mm - this provides a clean reset and prevents spurious resets from EMI. Route the ICSP clock (RB6/PGC, pin 27) and data (RB7/PGD, pin 28) lines symmetrically with no stubs, and reserve an ICD header footprint even if the production design does not populate it.
Estimated: at 25 C ambient and full 25 I/O switching at 20 MHz with 10 pF loads per pin, internal dissipation is below 50 mW - the 28-SSOP package (theta_JA ~ 95 C/W per typical Microchip data) handles this with negligible temperature rise. Continuous output loads above 20 mA per pin require thermal relief copper pours. Always check the Microchip DS41291F thermal table for production designs.
Do not forget to configure the ADC port pins as analog via the ANSEL register; leaving them digital adds noise and degrades ADC accuracy. The enhanced CCP module requires correct configuration of TRIS bits on P1A-P1D, otherwise the PWM outputs will not drive the I/O. When migrating from PIC16F877A, note that PIC16F886 has different ADC channels on PortB and requires firmware re-mapping.
