PIC16F1827-E/SS Overview
A PIC (Peripheral Interface Controller) microcontroller is a Harvard-architecture, RISC-based single-chip computer optimized for embedded control tasks. The PIC16 family sits in Microchip's mid-range portfolio, providing 8-bit data paths, low power consumption, and rich peripheral integration at low cost. Designers choose PIC16F parts when deterministic interrupt latency, long battery life, and integrated peripherals (ADC, PWM, I2C/SPI/UART, mTouch) outweigh the need for 32-bit performance. PIC16F1827 sits at the upper end of the mid-range, with XLP nanoWatt technology extending sleep current into the nanoampere range.
Key features include 7 KB (4K x 14) self-writeable Flash, 384 bytes SRAM, 256 bytes EEPROM, an internal 32 MHz oscillator selectable down to 31 kHz, an on-chip 10-bit ADC with up to 12 channels, two analog comparators, a DAC module, multiple Timer/PWM modules, Enhanced USART, MSSP (I2C/SPI), mTouch capacitive-touch sensing hardware, and a 16-level deep hardware stack. The XLP sleep current is typically below 20 nA with retention, and the part supports 1.8 V to 5.5 V VDD operation.
The PIC16F1827 uses Microchip's enhanced mid-range core with a hardware multiplier and 49 base instructions, executing most instructions in one oscillator cycle. The integrated mTouch peripheral allows capacitive button, slider, and proximity sensing without external touch ICs. Internal configurable logic cells (CLC) and numerically controlled oscillator (NCO) blocks give designers fine-grained on-chip signal generation and routing.
Typical applications include ultra-low-power battery sensors, capacitive-touch user interfaces, consumer white goods and small appliances, IoT edge nodes, LED lighting control, and general-purpose 8-bit embedded control. The 20-pin SSOP footprint is well supported by hobbyists and OEMs alike using the PICkit, MPLAB Snap, or ICD debugger/programmer chains.
When designing with this part, allocate the SSOP-20 land carefully: pin 1 dot orientation matters and the SSOP-20 lead pitch is 0.65 mm. Use the XC8 compiler from MPLAB X IDE and Microchip's Code Configurator (MCC) plug-in to generate peripheral setup code automatically.

Typical Applications
PIC16F1827-E/SS is suitable for 7 applications: Ultra-Low-Power Battery Sensor Node, Capacitive Touch User Interface, Consumer White Goods and Small Appliances, IoT Edge Node with BLE/Wi-Fi Co-Processor, LED Lighting Control and Dimming, Automotive Interior and Body Electronics, Industrial Process Sensor and Transmitter.
Ultra-Low-Power Battery Sensor Node
The PIC16F1827-E/SS is purpose-built for battery-powered wireless sensor nodes thanks to its XLP nanoWatt technology with sleep current typically below 20 nA and 1.8 V to 5.5 V VDD range that allows direct connection to a single CR2032 coin cell or two AA cells. Its 32 MHz HF oscillator wakes the part in microseconds for fast ADC sampling, then returns to deep sleep between events. The integrated 10-bit ADC, two analog comparators, and mTouch capacitive sensing eliminate external analog ICs, reducing BOM cost. A typical 1 Mbit/s EUSART link to a sub-GHz radio module completes the IoT node. Power budgets of <2 uA average are achievable with duty-cycled wake cycles, ideal for 10-year battery life designs in cold-chain monitoring, water/gas meters, and asset tracking.
Recommended
Capacitive Touch User Interface
The PIC16F1827-E/SS integrates Microchip's mTouch hardware peripheral, supporting up to 12 touch channels with hardware-driven charge-time acquisition and minimal CPU overhead. This makes it ideal for sealed-button appliance interfaces, slider controls, and proximity-sensing industrial panels where mechanical switches are unreliable. Designers can implement 9-glow or 12-button panels without external touch ICs, reducing PCB size and BOM. The integrated DAC and PWM modules also support LED dimming feedback through the same capacitive pads. With 7 KB Flash and 384 bytes RAM, the firmware comfortably fits mTouch library plus custom UI state machine. Operating at -40C to +125C ensures reliable touch detection in outdoor or under-hood environments.
Recommended
Consumer White Goods and Small Appliances
The PIC16F1827-E/SS is widely deployed in coffee makers, blenders, washing-machine control boards, and microwave ovens because it combines multiple analog comparators, PWM channels, and EUSART in a single 20-pin SSOP. The 32 MHz CPU can run a multi-tasking control loop with brushed-DC motor PWM, temperature sensing, and user-LED indicators concurrently. Its extended -40C to +125C temperature grade supports under-hood and unventilated enclosures. The integrated hardware multiplier and 16-level stack simplify math for sensor linearization. With 256 bytes EEPROM, designers store user settings across power cycles without external memory. The SSOP-20 footprint is hand-solderable for low-volume production runs.
Recommended
IoT Edge Node with BLE/Wi-Fi Co-Processor
The PIC16F1827-E/SS pairs naturally as an ultra-low-power host MCU controlling sensors and a Wi-Fi/BLE co-processor such as the RN4870 or ESP-AT module. Its EUSART and MSSP (I2C/SPI) interfaces connect to virtually any wireless module, while the 10-bit ADC reads environmental sensors with hardware averaging. The XLP sleep current enables months of standby on a coin cell between BLE beacons. Pin-to-pad versus the SSOP-20 footprint matches small module carriers. With 7 KB Flash, the MCU runs AT-command parser, sensor sampling, and event-driven wake logic without external memory. Industrial -40C to +125C range supports outdoor IoT deployments.
Recommended
LED Lighting Control and Dimming
The PIC16F1827-E/SS integrates a 10-bit DAC, 10-bit ECCP PWM, and multiple CCP channels that handle constant-current LED dimming, color mixing, and programmable fade patterns in a single chip. Designers can drive RGBW LED strips directly with PWM outputs or use the DAC for analog reference to constant-current drivers. The 32 MHz CPU executes smooth fade algorithms with 16-bit PWM granularity. mTouch inputs allow touch-based brightness/color control without mechanical knobs. With XLP low-power sleep modes, battery-powered decorative lighting and portable lanterns achieve weeks of runtime. The SSOP-20 footprint fits inside small inline LED controllers.
Recommended
Automotive Interior and Body Electronics
While not AEC-Q100 qualified, the PIC16F1827-E/SS with its -40C to +125C extended temperature grade finds use in non-safety automotive interior modules such as ambient lighting controllers, HVAC blend-door actuators, and seat-memory switches. The integrated mTouch allows capacitive seat controls and dashboard buttons without mechanical wear. Enhanced USART communicates with body control modules (BCM) over LIN-style networks. PWM channels drive LED backlighting and small solenoids. The 7 KB Flash stores calibration tables and user preferences in 256 bytes EEPROM. Designers should note that AEC-Q100 variants like PIC16F1827-E/SSVAO are required for safety-critical automotive nodes.
Recommended
Industrial Process Sensor and Transmitter
The PIC16F1827-E/SS is ideal for 4-20 mA loop-powered industrial transmitters and remote process sensors because of its wide VDD range, low sleep current, and integrated 10-bit ADC with internal voltage reference. The hardware multiplier accelerates scaling and linearization of RTD/thermocouple signals. EUSART outputs 4-20 mA via PWM-to-current conversion or Modbus RTU over RS-485. With 256 bytes EEPROM, calibration constants and unit IDs are stored permanently. The -40C to +125C range handles outdoor and factory-floor environments. The SSOP-20 footprint fits inside standard industrial DIN-rail transmitter housings alongside isolation barriers.

- Extended -40C to +125C temperature grade in same silicon (vs PIC16F1827-I/SS)
- On-chip DAC and CLC logic cells (vs PIC16F1936)

Design Notes
Estimated power savings: PIC16F1827-E/SS XLP sleep current is typically below 20 nA with full SRAM retention. For a CR2032 (220 mAh) battery, this allows over 10 years of standby life at room temperature, but subtract ~50% at -20C cold conditions for lithium coin-cell capacity loss. Always enable the WDT, BOR, and put all unused peripherals in their lowest power state via the PMDx register before WFI sleep. Use LFINTOSC (31 kHz) during sleep-mode housekeeping to minimize HFOSC start-up current spikes.
SSOP-20 has 0.65 mm pitch and 5.30 mm body. Follow JEDEC J-STD-020 reflow profile with peak temperature below 260C for lead-free. Place the ICSP/ICD connector footprint on the board with VPP/MCLR/VSS/ICSPCLK/ICSPDAT accessible from a header or test pad - this enables in-system programming without removing the MCU. Add 0.1 uF decoupling capacitor as close to pin 20 (VDD) as possible, plus a bulk 1-10 uF near the VDD pin. Leave a copper pour under the SSOP body but do not connect to VDD/VSS without proper thermal relief.
Do not confuse the E temperature grade (-40C to +125C) with the I grade (-40C to +85C) in the part number - the silicon die is the same but the spec'd operating range differs. Do not leave ICSPCLK/ICSPDAT floating; add weak pull-ups (10-100 k) or the device may enter programming mode inadvertently. The MCLR pin (pin 1) must have a pull-up to VDD if not used, otherwise the part will see an undefined reset. Configure the configuration bits (CONFIG1, CONFIG2) for the right oscillator, watchdog, and code-protect settings; default unprogrammed values are unsuitable for production.
Keep analog (ANx) traces away from digital switching signals (PWM outputs, ICSPCLK, crystal). The mTouch sense traces must be guarded by a ground ring and not run parallel to noisy traces. For capacitive touch sensors, trace length should be kept short (under 100 mm) and width consistent. Route the crystal traces symmetrically with a ground guard trace between them to prevent oscillator noise injection. Place the VDD decoupling within 2 mm of the package pin.
