Key differentiating features of the PIC16LF818T-I/SSTSL include a wide 2.0 V to 5.5 V operating range, 16 general-purpose I/O, an internal 8 MHz oscillator (calibrated +/-1%), two analog comparators, a 10-bit ADC with up to 5 channels, two 8-bit timers plus one 16-bit timer, and a synchronous serial port configurable for SPI or I2C. The 'I' suffix indicates the industrial -40C to +85C temperature grade, while 'SL' denotes a 20-SSOP tape-and-reel packing variant. Architecturally the device pairs a 14-bit wide program word with an 8-bit data path, supported by a 35-instruction RISC-like set, hardware stack, and integrated brown-out reset plus power-on reset. Compared with larger PIC18 devices, the PIC16LF818T-I/SSTSL trades program memory depth for the smallest pin-count SSOP footprint in the family, making it ideal when PCB real estate is at a premium but full peripheral integration is still required. Typical applications include sensor node signal conditioning, low-power IoT end-node controllers, battery management slave controllers, industrial 4-20 mA loop peripherals, and consumer white-goods user interfaces. Designers typically pair it with a PICkit programmer for in-circuit serial programming and use MPLAB X IDE with the XC8 compiler for firmware development. When designing, verify that the application's peripheral mix does not exceed the SSOP-20 pin budget, and add a 0.1 uF decoupling capacitor within 5 mm of VDD. The internal 8 MHz oscillator reduces BOM cost but offers less accuracy than an external crystal.

Key specifications include an internal 8MHz oscillator (with selectable 31kHz LF oscillator and external oscillator options), 256 bytes of data EEPROM, 5 channels of 10-bit ADC, two 8-bit timers plus one 16-bit timer, a Capture/Compare/PWM module, an addressable USART, and an SPI/I2C MSSP peripheral. Five digital I/O ports are available on the 18-pin package, with Wake-on-Change interrupts on port pins. The device consumes roughly 100 uA active at 1 MHz / 2.0V and drops into the sub-microamp range for sleep currents, ideal for battery telemetry. Typical applications include remote sensor nodes, battery-backed thermostats, simple motor control, LED drivers, HVAC accessory boards, and small appliance user-interface controllers. The PIC16LF819T-I/SO is also used as a glue/controller MCU for system management tasks in larger designs where a full 32-bit core would be overkill. Designers should consult the PIC16F819 family datasheet for the LF-grade electrical characteristics and the latest MPLAB XC8 toolchain support. Pin-compatible variants (PIC16LF818, PIC16LF819-I/SO non-T) drop directly onto the same SOIC-18 footprint, enabling reuse across product variants. This page synthesizes distributor pricing, drop-in alternatives in the same 18-pin SOIC footprint, and practical design notes that are not aggregated in the manufacturer datasheet alone.

PIC16LF819T-I/SOG

PIC16LF819T-I/SOG - 8-Bit 10MHz 3.5KB FLASH MCU | Microchip

The Microchip Technology PIC16LF819T-I/SOG is an 8-bit PIC microcontroller with a 10MHz CPU, 3.5KB (2K x 14) of Flash program memory, 256 bytes of SRAM and 256 bytes of EEPROM, housed in an 18-pin SOIC (SOG) package supplied on tape and reel. The 'LF' family variant operates across 2.0V to 5.5V, supporting 2.5V/3.3V/5V rails common in battery-powered and industrial systems. The 'T' suffix denotes Tape & Reel packaging and 'I' denotes the -40C to +85C industrial temperature grade. What is an 8-bit PIC microcontroller? It is a Harvard-architecture RISC processor that executes one instruction per cycle (except branches) and is widely used in embedded control for its deterministic behaviour, low power, and broad peripheral integration. Within the broader product hierarchy, the PIC16F family sits between the smaller PIC10/12/16 baseline families and the PIC18 mid-range and PIC32 MIPS-based families. PIC microcontrollers are commonly chosen for sensor interfacing, LED driving, user I/O expansion, and low-cost motor control. Key features of the PIC16LF819T-I/SOG include the nanoWatt Technology power-management suite with multiple sleep modes and dynamic oscillator switching, an internal 8MHz/32kHz oscillator, 16 I/O pins, a 10-bit ADC with up to 8 channels, PWM/SCCP/ECCP capture-compare modules, an MSSP for SPI/I2C, an enhanced USART for LIN/RS-232, and an ICD2/ICSP in-circuit programming/debug interface. The Flash-based program memory supports up to 100K erase/write cycles typical, with internal self-programmability under software control. The device integrates a precision 1% internal oscillator that often eliminates the external crystal, reducing BOM cost and PCB area. Brown-out Reset, Power-on Reset, Watchdog Timer with its own on-chip RC oscillator, and a programmable Low-Voltage Detect circuit provide robust single-supply operation suitable for unattended or remote installations. Typical applications include industrial sensor conditioning, low-power remote keyless entry, consumer appliance control, battery chargers, small fan/lighting controllers, and low-cost instrumentation front-ends. The 256-byte EEPROM is particularly useful for storing calibration constants, serial numbers and user preferences that survive power cycles. When designing with this part, place decoupling capacitors within 3mm of the VDD/AVDD/VSS pins and route the ICSPDAT/ICSPCLK traces away from switching nodes to maintain clean in-circuit debug signals. For low-power designs, switch the system clock to 31kHz internal and place the device in Sleep mode between interrupts - this typically reduces I-DDT to single-digit microamp levels per the datasheet nanoWatt specifications.

PIC16LF83-04/P

PIC16LF83-04/P - 8-bit PIC MCU, 896B Flash, 4MHz, 18-DIP | Microchip

The Microchip Technology PIC16LF83-04/P is a low-power 8-bit CMOS RISC microcontroller belonging to the PIC16CXX family, packaged in a 18-pin PDIP (0.300 inch, 7.62 mm) through-hole package. It executes instructions at up to 4 MHz from 896 bytes (512 x 14) of FLASH program memory and provides 36 bytes of RAM plus 64 bytes of EEPROM data memory, with 13 digital I/O pins arranged on two ports (PORTA 5-bit, PORTB 8-bit). A microcontroller (microcontroller unit, MCU) is a single-chip computer integrating a CPU, RAM, program memory, I/O peripherals and interrupt logic. The PIC16F8X family employs an advanced RISC Harvard architecture with only 35 single-cycle instructions, making it one of the simplest and most deterministic 8-bit MCU platforms. PIC microcontrollers sit within the broader hierarchy of microcontrollers -> microprocessors -> digital logic ICs -> integrated circuits -> semiconductors, and are widely used as embedded controllers. Key features of the PIC16LF83-04/P include a 14-bit instruction word, 8-level deep hardware stack, 4 oscillator options (RC, LP, XT, HS), an 8-bit timer/counter (TMR0) with 8-bit prescaler, a watchdog timer with on-chip RC oscillator, power-on reset, power-up timer, and brown-out reset, plus an in-circuit serial programming (ICSP) interface. The 'LF' prefix denotes the low-power (LF) process variant optimised for battery operation at 2.0V to 6.0V, while the '04' speed suffix denotes the 4 MHz maximum clock at 5V. Technically, the device features separate 13-bit program and 8-bit data buses (Harvard), allowing simultaneous instruction fetch and data access. Each instruction executes in one oscillator cycle (4 clock periods), giving an effective 1 MIPS throughput at 4 MHz. The high-current sink/source capability on PORTB (25 mA per pin) allows direct LED drive, while PORTA supports analog comparator inputs. Typical applications include low-power remote controls, sensor interface nodes, consumer appliance controllers, battery-backed instruments, simple LED drivers, and educational/development boards. Its through-hole 18-DIP package remains popular for hobbyist prototyping, breadboarding, and legacy industrial controllers. When designing with this MCU, ensure the configuration word selects an oscillator mode matching the external crystal or RC network. Use ICSP for firmware updates and observe minimum Vdd rise time to avoid power-on reset issues. The PIC16LF83-04/P is functionally a precursor to the PIC16F84A and shares most peripherals but lacks the latter's enhanced USART.

PIC16LF83T-04/SO - 4MHz 8-bit FLASH MCU 18-SOIC | Microchip

The Microchip Technology PIC16LF83T-04/SO is an 8-bit RISC flash microcontroller with 4 MHz maximum clock speed, 896 bytes of FLASH program memory (512 x 14 words), 36 bytes of RAM, and 13 digital I/O pins, housed in an 18-pin SOIC wide-body package with tape-and-reel packaging. The "LF" suffix denotes the low-voltage variant supporting an operating voltage range of 2.0 V to 6.0 V, making it compatible with both 3.3 V and 5 V system rails. The "T" indicates tape-and-reel packaging, and the "-04" denotes the 4 MHz oscillator option. A PIC microcontroller (Programmable Interface Controller) is a family of 8-bit RISC-based microcontrollers originally developed by General Instrument's Microelectronics Division and now produced by Microchip Technology. PIC MCUs belong to the broader hierarchy: microcontroller -> embedded controller -> semiconductor IC, and they are widely used for low-cost, low-power embedded control applications. The PIC16F family was the first FLASH-based PIC16 architecture, replacing the older OTP and windowed EPROM variants, and provides in-system self-programmability for firmware updates. Key features include a 14-bit instruction set, 35 single-word instructions at 200 ns execution time, two 8-bit timers (Timer0, Timer2) and one 16-bit timer (Timer1), a watchdog timer with on-chip RC oscillator, 8-bit ADC channel option via shared I/O, internal 4 MHz RC oscillator, and an integrated power-on reset / brown-out reset / MCLR circuit. The peripheral set also includes a synchronous serial port (SSP) supporting SPI and I2C master/slave modes. The PIC16LF83T-04/SO is built around a Harvard-architecture RISC CPU with separate program and data buses, an 8-level deep hardware stack, and direct/indirect addressing modes. The 35-instruction RISC core provides predictable timing suitable for real-time embedded control, and the integrated ICE (In-Circuit Emulator) debug interface allows developers to debug firmware directly on the target board using Microchip's MPLAB ICD tools. Typical applications include low-cost consumer appliances, sensor signal conditioning nodes, battery-powered remote controllers, LED lighting drivers, simple industrial control logic, and educational microcontroller projects. The 18-SOIC wide-body package provides easy hand-soldering and breadboard-friendly footprints, while the wide 2.0-6.0 V supply range simplifies battery- and USB-powered designs. When designing with this device, allocate a 4-pin ICSP header (VDD, VSS, MCLR, RB7, RB6) for in-circuit serial programming and consider using an internal 4 MHz oscillator to reduce BOM cost. The 13 I/O pins share analog functions, so plan pin assignments carefully if the ADC is used, and reserve a free timer-capable pin (e.g., RB4-RB7) for PWM or event-count applications. This page synthesizes distributor pricing, parametric specifications, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone. Engineers searching for a direct PIC16F83 or PIC16LF83 replacement in SOIC-18 will find verified drop-in candidates and a side-by-side comparison here.
