PIC16LF1827T-I/ML - 7KB Flash 8-bit MCU 32MHz 28-QFN | Microchip

The Microchip Technology PIC16LF1827T-I/ML is a low-power 8-bit PIC microcontroller from the PIC16F/LF182x enhanced mid-range family, built on nanoWatt XLP technology and offering 7 KB of Flash program memory, 384 bytes of RAM, and 32 MHz internal oscillator performance in a 28-pin QFN (6x6 mm) package with an exposed pad. What is a PIC microcontroller? A PIC (Peripheral Interface Controller) is a family of 8-bit, 16-bit, and 32-bit microcontrollers built on a Harvard RISC architecture by Microchip Technology. Within the PIC portfolio the LF (low-voltage) sub-family operates from 1.8 V to 3.6 V and is optimized for battery-powered applications. The PIC16LF1827 sits in the enhanced mid-range core family (PIC16), offering 49 instructions, 16-level hardware stack, and C-compiler friendly architecture with up to 32 MHz operation. It belongs to the broader semiconductor hierarchy: microcontroller -> embedded MCU -> power management integrated circuit (system context). Key features include 7 KB Flash program memory, 384 bytes RAM, 256 bytes EEPROM, 16 I/O pins, 12-channel 10-bit ADC, two 8-bit timers and one 16-bit timer, an Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART), two MSSP blocks supporting SPI and I2C (both Master and Slave), a 32 MHz internal oscillator, and mTouch capacitive-touch sensing peripherals. The device supports In-Circuit Serial Programming (ICSP) via two pins and offers nanoWatt XLP sleep currents as low as 30 nA typical. Architecturally, the PIC16LF1827 integrates a high-performance RISC CPU with a hardware multiplier, CWG (Complementary Waveform Generator), configurable logic cells, and 2 x PWM modules with independent time bases. The integrated 32 MHz internal oscillator eliminates the need for an external crystal in most cost-sensitive designs and supports factory-calibrated accuracy within +/- 2 percent across the industrial temperature range. Typical applications include low-power sensor nodes, capacitive-touch user interfaces, LED lighting controllers, consumer appliances, IoT edge devices, and battery-powered instrumentation. The combination of XLP sleep current, mTouch peripherals, and integrated peripherals makes it ideal for human-machine interface nodes that must operate for years on a single coin cell. When designing with this part, place a 0.1 uF decoupling capacitor as close as possible to the VDD pin and a 1 uF bulk capacitor near the exposed thermal pad (EP), which must be soldered to a low-impedance ground plane for electrical and thermal performance. The internal oscillator is sufficient for most UART and SPI applications up to 32 MHz; only timing-critical designs (USB, high-precision PWM) need an external crystal.

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.

PIC16LF1828-I/SO - 8-bit XLP MCU 7KB Flash 32MHz 20-SOIC | Microchip

The Microchip Technology PIC16LF1828-I/SO is a low-power 8-bit PIC16 enhanced mid-range microcontroller with 7 KB Flash program memory, 256 bytes RAM, and an integrated 32 MHz internal oscillator, housed in a 20-pin SOIC package. The "LF" prefix indicates the extended battery-life XLP variant, supporting a wide operating voltage range from 1.8V to 3.6V with nanoWatt XLP technology for sleep currents in the tens of nanoamperes. A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, timers, communication peripherals, and I/O pins. The PIC16 enhanced mid-range core is a RISC architecture with 49 instructions and 200 ns instruction execution time at 20 MHz (16 MIPS). PIC16 MCUs sit in the taxonomy: microcontroller -> embedded MCU -> 8-bit MCU -> PIC family -> PIC16 enhanced mid-range -> XLP (eXtreme Low Power) family. These devices are designed for battery-powered and energy-harvesting designs where low sleep current and peripheral flexibility outweigh raw CPU throughput. Key features of the PIC16LF1828-I/SO include 7 KB (4K x 14) Flash program memory, 256 bytes of RAM, 256 bytes of EEPROM, 18 general-purpose I/O pins, 12 channels of 10-bit ADC, one Enhanced USART (EUSART), two SPI/I2C MSSP peripherals, four 8/16-bit timers, and a 32 MHz internal oscillator accurate to within ±1% (HFINTOSC). The device integrates mTouch capacitive-touch sensing hardware and a Complementary Waveform Generator (CWG) for driving power-conversion stages. An on-chip temperature indicator, in-circuit debugger (ICD), and nanoWatt XLP sleep modes (down to ~20 nA typical) complete the feature set. Typical applications include capacitive-touch user interfaces, IoT sensor nodes, battery-powered remote controls, low-power medical wearables, energy-harvesting wireless sensor endpoints, and general-purpose embedded control. The 20-pin SOIC package is a JEDEC-standard wide-body surface-mount outline with hand-solderable leads and reliable reflow characteristics for industrial and consumer designs. Pin-compatibility across the PIC16LF182x family allows upgrade/downgrade without PCB redesign. When designing with this MCU, note that the LF voltage range (1.8V to 3.6V) differs from the F variant (1.8V to 5.5V); mixing the two in mixed-voltage rails requires level translation. Use the MPLAB X IDE with XC8 compiler for code development; debug requires a PICkit 3, MPLAB ICD 3/4, or Curiosity development board. The integrated ICD eliminates the need for an external debug header on most pins.

It operates from 1.8 V to 3.6 V, with the PIC16LF1829 specifically tuned for low-voltage nanoWatt XLP applications while a sibling PIC16F1829 variant extends to 5.5 V. The device offers 12 enhanced I/O pins, a 10-bit ADC with automatic threshold scanning, a 5-bit DAC, comparators, mTouch capacitive touch hardware, and serial interfaces including EUSART, I2C and SPI. An 8-bit microcontroller (MCU) is a single-chip computer that combines a CPU core, non-volatile program memory (Flash), volatile data memory (RAM) and configurable peripherals such as timers, ADCs and communication interfaces. PIC microcontrollers use a RISC Harvard architecture with a separate program and data bus, optimized for deterministic real-time control. They occupy the position of microcontrollers -> embedded controllers -> microprocessors in the broader system hierarchy, and the 'LF' prefix denotes a low-voltage variant optimized for battery-powered designs, while 'XLP' (eXtreme Low Power) refers to Microchip's nanoWatt technology family delivering deep-sleep currents down to the tens of nA range. Key features of the PIC16LF1829 include 14 KB Flash (8K x 14 instruction words), 1 KB RAM, mTouch capacitive touch sensing, an enhanced 16-bit PWM with complementary outputs for power-conversion control, peripheral pin select (PPS) for flexible routing, and two ICSP programming pins plus an integrated debug interface that eliminates the need for an external debug header. The 10-bit ADC supports hardware averaging and threshold-triggered wake-up, while the ECCP module can drive half-bridges or full H-bridges directly. Architecturally, the PIC16LF1829 uses Microchip's enhanced mid-range 8-bit core with a 14-bit instruction word and an 8x8 hardware multiplier. Its deep-sleep mode with RTCC keeps the device below 50 nA typical while still allowing periodic wake-up, and PPS allows digital peripherals to be mapped to almost any I/O pin, simplifying PCB layout. Typical applications include battery-powered sensor nodes, capacitive touch user interfaces, low-energy IoT edge devices, IR/consumer remote controls and small kitchen appliances. The rich peripheral set and low-power operation make it well-suited for always-on designs running from coin cells or harvested energy. When designing with this part, place a 0.1 uF decoupling capacitor as close as possible to VDD and use PPS to map peripheral functions to convenient pins. For ultra-low standby power, disable unused peripherals and use the deep-sleep mode with RTCC for scheduled wake-up.

Power consumption is among the lowest in the class: 1.8 V operation at 32 kHz standby draws under 1.3 µA, and sleep currents below 20 nA make it suitable for battery-powered sensor nodes. The enhanced mid-range architecture adds interrupt context saving, a hardware multiplier, and a deeper stack, supporting deterministic real-time response for motor, lighting, and IoT edge workloads. The mTouch block performs capacitive measurement without external active components, eliminating the BOM cost of dedicated touch ICs. Typical applications include battery-powered IoT sensor nodes, capacitive touch user interfaces, portable consumer electronics, LED lighting controllers, and low-power wireless sensor nodes. It also fits as a co-processor for housekeeping and wake-up functions in larger systems. When designing with this part, ensure the supply is decoupled with 100 nF plus 10 µF ceramic capacitors within 5 mm of VDD; use the LF variant when the rail stays under 3.6 V to gain maximum XLP benefit.
