PIC16LF1828-E/SS - 8-bit XLP MCU, 7KB Flash, 32MHz | Microchip
MPN: PIC16LF1828-E/SS ✓ فعالPIC16LF1828-E/SS جائزہ
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), volatile data memory (RAM), and a rich set of peripherals (timers, ADC, communications, I/O) onto one silicon die. Within the broader semiconductor taxonomy, an MCU belongs to: microcontroller -> embedded processor -> integrated circuit -> semiconductor. The PIC16LF1828 family sits at the low-power / mixed-signal node of that tree, prioritizing active performance per milliwatt and deep-sleep retention for battery and energy-harvesting designs.
Key features include 7 KB self-programmable Flash, 256 B SRAM, 256 B EEPROM, an internal 32 MHz oscillator with PLL, an on-chip 10-bit ADC with up to 12 channels, two 8-bit timers plus one 16-bit timer, enhanced PWM, configurable logic cells (CLC), mTouch capacitive touch sensing, and EUSART / I2C / SPI serial interfaces. The device provides 17 general-purpose I/O pins with individual pull-up, interrupt-on-change, and weak pull-up control. This combination delivers high analog/mixed-signal integration in a footprint smaller than most discrete plus-MCU solutions.
Architecturally, the part uses a 14-bit instruction word modified Harvard pipeline with a hardware multiplier and a hardware CLC fabric that lets designers route peripheral signals without external gates. The internal 32 MHz oscillator factory-calibrated to within 1% supports USB-style timing tolerances via Fosc postscaler while still allowing low-power 31 kHz LF operation. The nanoWatt XLP technology uses dynamic peripheral gating so unused modules contribute <50 nA bias current.
Typical applications include low-power wireless sensor nodes, IoT battery-powered edge devices, consumer remote controls, mTouch capacitive touch keypads, LED lighting controllers, and portable medical monitors. Designers also deploy it in sensor hubs, smart thermostats, and low-end motor-control auxiliaries. The wide 1.8V–3.6V range allows direct Li-ion / 2xAA battery operation, while extended temperature parts serve automotive under-hood and industrial control environments.
When designing with this device, prioritize pin assignment early - the EUSART, I2C, and PWM outputs are remappable, while the ICSP/ICD pins (RB6/RB7) and the Vpp/MCLR must remain accessible for programming. Use the internal 32 MHz HFINTOSC to reduce external component count, but verify USB orlin tolerance for your protocol stack. Decouple VDD/VSS with at least 100 nF plus 1 uF bulk, and use the on-chip LDO regulator with a 10 uF tank cap for noise-sensitive analog rails.

Battery-Powered IoT Sensor Node
The PIC16LF1828-E/SS fits battery-powered IoT sensor nodes because its 1.8V to 3.6V supply range accepts direct 2xAA or single-cell Li-ion, and nanoWatt XLP deep-sleep currents of ~20 nA extend battery life to multi-year levels on 2xAA cells. Its 7 KB Flash holds typical sub-GHz or LoRaWAN-class firmware stacks with sensor calibration tables, while the 10-bit ADC reads temperature, battery voltage, and ambient light with up to 12 analog channels. EUSART/SPI/I2C connect to radios like Microchip's MRF89XA or external sensors; CLC routes wake-up events without CPU intervention, reducing active-mode duty cycle below 0.1%. The SSOP-20 footprint fits in 8 mm x 6 mm PCB areas typical of coin-cell and AA-packaged wireless sensors.

mTouch Capacitive Touch Keypad
The PIC16LF1828-E/SS integrates Microchip's mTouch capacitive touch sensing module, which uses the on-chip ADC plus a software library to scan up to 12 touch electrodes without external touch ICs - reducing BOM cost and PCB area in user-interface panels. The 32 MHz core completes a full electrode scan in under 2 ms while the nanoWatt XLP sleep mode drops quiescent current below 5 uA between button presses, enabling battery-powered remote controls and sealed keypads. The 17 GPIO pins support both touch electrodes and LED drive, with CLC implementing proximity wake without main-loop polling. Designers typically route 4-12 touch pads through PORTA/PORTB and use the EUSART for IR or RF transmission of touch events.

Portable Medical Health Monitor
The PIC16LF1828-E/SS suits portable medical health monitors where battery life, small PCB area, and reliable operation over the -40C to +125C extended industrial range matter most. Its 1.8V to 3.6V supply lets it run directly from a CR2032 coin cell while the 10-bit ADC samples pulse oximeter, temperature, or galvanic skin response signals. The CLC fabric implements digital filters and pulse-edge detection without burning CPU cycles, and the ECCP module drives haptic feedback or buzzer PWM. nanoWatt XLP sleep at ~20 nA is critical for medical devices that may sit idle for months between uses; the on-chip EEPROM stores patient calibration history and device serial numbers non-volatilely.

Industrial Sensor Hub / Process Transmitter
In industrial sensor hubs and 4-20 mA process transmitters, the PIC16LF1828-E/SS provides the low-power intelligence needed for loop-powered or battery-backed field instrumentation. The extended -40C to +125C temperature grade handles unheated outdoor enclosures and factory-floor heat, while the 1.8V-3.6V supply fits both 24 V loop-powered designs (after regulation) and 3.6V Li-ion backup packs. The 10-bit ADC digitizes pressure, flow, or level transducers with up to 12 channels, and the EUSART outputs 4-20 mA HART or RS-485 Modbus signals. CLC implements HART modem shaping without external components, while the 7 KB Flash stores linearization tables and Modbus register maps.

LED Lighting Controller / Driver
The PIC16LF1828-E/SS drives LED lighting controllers thanks to its Enhanced Capture/Compare/PWM (ECCP) module that generates multi-channel PWM with programmable dead-band, allowing smooth dimming and color-mixing across RGB or RGBW strings. Its 32 MHz core resolves 16-bit PWM at ~488 Hz, well above the flicker-fusion threshold for human-perceptible lighting. The 1.8V-3.6V supply matches single-cell Li-ion fixtures, and the CLC fabric implements zero-cross TRIAC dimming detection or DALI signaling without an external logic IC. nanoWatt XLP sleep mode cuts standby power below 0.1 W in always-connected smart bulbs, an essential feature for ENERGY STAR compliance.

Consumer Remote Control (IR / RF)
The PIC16LF1828-E/SS powers consumer IR or RF remote controls where its 1.8V-3.6V supply drives directly off two AAA cells, the nanoWatt XLP sleep keeps standby current below 50 nA for multi-year battery life, and the 32 MHz core generates accurate 38 kHz IR carrier waveforms via the ECCP module. The 17 GPIO scan a 4x4 or 5x5 key matrix, and the EUSART drives external RF transceivers for Bluetooth Low Energy or proprietary 2.4 GHz protocols. CLC implements button-press debouncing and repeat-code generation without CPU wakeups, while the on-chip EEPROM stores pairing keys and device codes non-volatilely. The SSOP-20 package fits into slim remote-control enclosures under 10 mm thick.

Low-End Brush Motor Aux Controller
The PIC16LF1828-E/SS acts as an auxiliary controller in low-end brush DC motor applications, providing speed control via PWM, current sensing via the 10-bit ADC, and fault protection via CLC-based comparator logic. The 1.8V-3.6V supply fits 2-cell Li-ion or 3.6V regulated packs typical of small appliances, toys, and personal care devices. The extended -40C to +125C temperature grade handles enclosed motor environments where ambient can exceed 70C. EUSART and I2C connect to a host MCU for command/status exchange, while 256 B of EEPROM stores trim parameters and runtime hours. The 7 KB Flash implements PI control loops and soft-start profiles without external DSP hardware.

ڈیزائن نوٹس
The PIC16LF1828-E/SS operates from 1.8V to 3.6V on VDD (pin 1) with VSS on pin 8. Decouple VDD with at least 100 nF plus 1 uF bulk placed within 5 mm of the supply pin; for noise-sensitive analog rails add a 10 uF tantalum or ceramic tank. Enable the internal voltage regulator's tank capacitor (typically 10 uF) on the VCAP pin if used. Brown-out-reset voltage is configurable; for Li-ion applications set BOR at ~1.8V to prevent Flash corruption on deep discharge. nanoWatt XLP sleep current at +25C is typically 20 nA with watchdog disabled - verify on your specific lot. Estimated based on datasheet typical characteristics and standard MCU decoupling practice.
Route the ICSP/ICD pins RB6 (pin 20) and RB7 (pin 19) to a 2x3 or 1x6 header for in-circuit programming and debugging - even production boards benefit from at least test-pad access for field firmware updates. Place a 10 kohm pull-up on MCLR/RA3 (pin 4) for clean reset; adding a 100 nF cap between MCLR and VDD provides hardware debouncing. Keep analog traces short and guarded from digital switching signals to preserve the 10-bit ADC accuracy; the SSOP-20 footprint allows standard 0.65 mm pitch trace routing on a 4-layer PCB. The exposed die pad is not present on SSOP - thermal dissipation is via the standard SSOP lead frame.
Do not exceed 3.6V on VDD - the LF silicon variant lacks the 5V tolerance of the F variant, and over-voltage will damage the part permanently. Do not leave the MCLR pin floating - always pull it high through a resistor. When using the internal 32 MHz HFINTOSC, verify the PLL settings in configuration words and avoid overlapping the HF and LF oscillator transitions; always switch to HFINTOSC before enabling peripherals that need higher clocks. Estimated rows = 3 common pitfall categories reviewed against datasheet configuration bits. Verify final configuration with MPLAB X IDE and a logic analyzer before locking down firmware. Also: do not omit the VCAP capacitor if using the on-chip regulator.
