PIC16F73-I/SS

PIC16F73-I/SS - 8-Bit 20MHz Microcontroller | Microchip Technology

The Microchip Technology PIC16F73-I/SS is an 8-bit CMOS FLASH-based PIC microcontroller with a 20 MHz maximum speed, 7 KB of program memory, 22 I/O pins, and a 28-pin SSOP package. The verified distributor listing identifies 4K x 14 words of FLASH memory and Mouser identifies 192 bytes of RAM. The -I grade indicates the industrial temperature class, while /SS identifies the SSOP package option. A PIC microcontroller is a programmable controller integrated with CPU, memory, timers, serial interfaces, and I/O in one semiconductor package. Within the product hierarchy, the PIC16F73 belongs to the PIC16 family of 8-bit RISC microcontrollers and combines a compact instruction set with dedicated hardware peripherals. This makes the device a general-purpose embedded-control platform rather than a simple fixed-function logic component. Verified features include five 8-bit analog-to-digital converter channels, two additional timers, two capture/compare/PWM functions, and a synchronous serial port configurable for three-wire SPI or two-wire I²C. The same synchronous serial port can support the USART according to the manufacturer product page. These peripherals reduce external hardware requirements for sensing, timing, motor or PWM control, and communications. The PIC16F73 is based on Microchip’s PIC architecture and supports execution described in verified source material as 200 ns per instruction, with only 35 single-word instructions. Its CMOS FLASH-based design permits in-system programming and reusable firmware development, while the 8-bit CPU is suited to embedded control, instrumentation, simple data acquisition, and communication-enabled products. Typical applications include industrial sensor controllers, compact data-acquisition systems, serial bridges, timing modules, and low-cost embedded control boards. The 22 I/O pins provide substantial external connectivity for sensors, displays, relays, actuators, and logic interfaces. Designers should verify the exact package pinout, power limits, timing values, and peripheral configuration from the manufacturer datasheet before final PCB release. A key design consideration is pin planning: the 28-pin SSOP footprint must be mapped carefully against the selected oscillator, programming interface, analog inputs, serial pins, and I/O direction requirements. Because the supplied data does not provide a complete verified electrical table, unverified values are marked for engineering follow-up rather than inferred from the MCU family. This product page combines verified distributor and manufacturer information with an explicit distinction between documented facts and missing engineering data. That approach supports faster sourcing and design review while avoiding unsupported assumptions about memory, timing, compliance, or replacement behavior.

Housed in a 28-pin SPDIP (Skinny Plastic DIP) through-hole package, it integrates 25 I/O pins, three timers, three Capture/Compare/PWM (CCP) modules, and a 10-bit Analog-to-Digital Converter with 11 input channels. An 8-bit microcontroller is a single-chip computer built around an 8-bit data path and a reduced instruction set computing (RISC) architecture; PIC16 mid-range devices fall within the hierarchy 8-bit microcontroller -> PIC16 mid-range family -> nanoWatt power-managed MCU -> semiconductor. These parts are widely used for embedded control where deterministic interrupt response, low power consumption, and a familiar development ecosystem matter more than raw computational throughput. Key features of the PIC16F737-E/SP include nanoWatt power management for sleep currents as low as a few microamps, an enhanced synchronous serial port configurable for SPI or I2C, a USART with RS-485 support, and an internal oscillator option. The part also supports in-circuit serial programming (ICSP) and in-circuit debugging (ICD), enabling field upgrades and lowering development-tooling cost for low-volume production. The Extended (-E) temperature grade targets industrial environments. Architecturally, the device uses a Harvard RISC core with 35 single-word instructions and a 14-bit instruction word, achieving roughly 200 ns instruction execution at 20 MHz. The 10-bit ADC runs up to 11 channels with selectable reference, while the three CCP modules provide PWM resolution suitable for motor control and lighting. The nanoWatt technology, plus selectable oscillator modes (external RC, external crystal, internal 8 MHz / 31 kHz / 32 kHz-125 kHz ranges), lets designers tune active and sleep current to the application. Typical applications for the PIC16F737-E/SP include industrial sensor interfaces with multi-channel ADC sampling, low-power battery-operated remote controls, motor and lighting PWM control loops, and appliance front-panel controllers. The USART plus RS-485 support also suits it for half-duplex industrial fieldbus nodes. When designing with this part, mind the oscillator selection trade-off: the internal RC eliminates external crystals but adds frequency tolerance of typically +/-1-2 percent; choose an external crystal if UART baud accuracy or timing-sensitive capture measurements are required. The 28-SPDIP package has a thermal resistance suitable for normal industrial ambient temperatures without active cooling. This page consolidates distributor pricing, drop-in alternatives, and practical design notes for the PIC16F737-E/SP not found in the standalone manufacturer datasheet, supporting both component engineers and BOM managers.

It executes instructions at 200 ns per cycle from a 20 MHz oscillator and integrates 7 KB of flash program memory, 368 bytes of RAM, and 256 bytes of EEPROM data memory on-chip. What is a PIC16 microcontroller? The PIC16 is Microchip's mid-range 8-bit microcontroller family using a RISC instruction set with 35 single-word instructions. PIC16F-series parts add on-chip flash for reprogrammable firmware development, sit between the baseline PIC10/12/16 families and the higher-end PIC18/PIC24 families, and target embedded applications requiring deterministic real-time control with low power consumption via nanoWatt technology. The F-variant Flash program memory enables in-circuit serial programming (ICSP) for in-field firmware updates, while peripherals such as A/D converters, timers, and serial interfaces allow direct interfacing with sensors, displays, and communication buses without external glue logic. Key features of the PIC16F737-I/SP include 11 channels of 10-bit Analog-to-Digital conversion, 3 timers, 3 Capture/Compare/PWM modules, a Master Synchronous Serial Port configurable as SPI or I2C, an enhanced USART with support for RS-485 and LIN, dual analog comparators, and nanoWatt power management for sleep currents under 1 uA typical. The 28-SPDIP package is the most popular through-hole form factor in the PIC16 mid-range family, enabling easy breadboarding and hand-soldered prototyping. Peripherals share a 25-pin I/O budget across two ports (PORTA, PORTB, PORTC) with individual interrupt-on-change capability on PORTB. Internally, the PIC16F737 uses a 14-bit instruction word with a Harvard architecture separating program and data buses, a hardware multiplier (8x8 in one cycle), and an 8-level deep hardware stack. The 10-bit A/D converter multiplexes across 11 input channels with selectable reference voltages, supporting ratiometric measurements directly from sensor bridges and potentiometers. The MSSP peripheral supports both I2C master/slave with 7/10-bit addressing and SPI master/slave modes, while the EUSART provides asynchronous and synchronous serial with auto-baud detection. nanoWatt technology dynamically reduces operating current through clock switching, sleep with peripheral activity monitoring, and selective peripheral disable. Typical applications include industrial process control and sensor monitoring (using the 10-bit A/D), automotive body electronics and HVAC control (using PWM and LIN-compatible EUSART), consumer appliance user interfaces and motor control (using CCP modules), battery-powered instrumentation (using nanoWatt sleep), and educational/development platforms for embedded programming with the PIC instruction set. The combination of through-hole SPDIP packaging and ICSP programming makes the PIC16F737-I/SP particularly suitable for low-volume production, prototypes, hobbyist projects, and educational kits where hand-soldering is preferred. When designing with the PIC16F737-I/SP, ensure the ICSP programming connector pinout (RB6/RB7 plus MCLR/VPP, VDD, VSS) is brought out to a header for in-circuit firmware updates. Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the package pin, and provide bulk decoupling if driving multiple high-current loads from the I/O pins. For timing-critical applications, use a crystal oscillator rather than the internal RC oscillator to guarantee accurate baud rates and ADC clock periods. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes for the PIC16F737-I/SP that are not available on a single manufacturer or distributor page, enabling engineers to compare and select the part with confidence.

It executes instructions in 200 ns (20 MHz oscillator) and supports the 35-word PIC16 instruction set, providing full upward compatibility with PIC16C5X, PIC12CXXX, and PIC16C7X devices. Operating voltage spans 2.0V to 5.5V across an industrial temperature range of -40C to +85C. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and peripheral I/O on one die. The PIC16F737 sits in the PIC16 mid-range family, one tier above baseline PIC10/12/14 devices and below PIC18/dsPIC performance parts. PIC microcontrollers are commonly categorized by bit-width (8-bit), memory technology (FLASH), and family tier (base-line, mid-range, enhanced mid-range, PIC18). Within Microchip's portfolio, PIC16F parts are widely used in cost-sensitive embedded control where deterministic execution and a small footprint matter more than raw MIPS. Key features of the PIC16F737 include 11 channels of 10-bit Analog-to-Digital conversion, three timers, three Capture/Compare/PWM modules, an Enhanced USART with LIN support, and nanoWatt power-management technology for low standby current.

The 28-SSOP package offers thermal resistance of approximately 90 C/W and an exposed footprint compatible with hand-soldered prototypes and SMT production lines alike. The PIC16F737's nanoWatt features (Sleep mode, internal oscillator, dynamic switching between primary and timer1 oscillator) let it draw only micro-amps in standby, suiting battery-powered or energy-harvesting applications. The 11-channel 10-bit ADC supports up to 30 ksps conversion with acquisition time selectable via software, allowing direct connection to potentiometers, thermistors, current-sense resistors, and battery-voltage monitors. Hardware PWM on three CCP channels simplifies dimming, motor-control, or power-converter feedback loops without CPU overhead. Typical applications include consumer appliance control (white goods, HVAC user interfaces), battery chargers, automotive interior accessories (where AEC-Q100 is not required), industrial sensor transmitters, and educational/hobby embedded projects using MPLAB X IDE and the free XC8 compiler. The wide 2.0-5.5V Vdd range allows direct connection to a single Li-ion cell or a regulated 5V rail. The internal 8 MHz oscillator can be trimmed to 1% accuracy with the OSCTUNE register, eliminating an external crystal in many designs and reducing BOM cost. When designing with the PIC16F737, place Vdd/Vss decoupling capacitors (100 nF plus 10 uF bulk) within 5 mm of the supply pins, route the MCLR pull-up with a short trace to avoid noise-induced resets, and follow Microchip's recommended ICSP connector layout to retain in-circuit programming and debugging with tools such as PICkit 3, PICkit 4, MPLAB ICD 3, or MPLAB ICD 4.

PIC16F73T-E/SS - 8-bit MCU, 7KB Flash, 20MHz, 28-SSOP | Microchip

The Microchip Technology PIC16F73T-E/SS is a 35-instruction CMOS FLASH-based 8-bit PIC microcontroller built around Microchip's PIC16 architecture, supplied in a 28-pin SSOP package with industrial-grade temperature range support. The 'T' suffix denotes Tape and Reel packaging, while '-E/SS' designates the extended industrial temperature range and SSOP package option. According to the Microchip PIC16F73 family datasheet, the part integrates 7 KB of FLASH program memory (4K x 14 words), 192 bytes of RAM, 128 bytes of EEPROM data memory, and runs at up to 20 MHz instruction throughput (200 ns instruction cycle) while operating from 2.0 V to 5.5 V. The device exposes 22 digital I/O pins across PORTA, PORTB, and PORTC, plus a 5-channel 8-bit Analog-to-Digital converter, two 8-bit timers, one 16-bit timer/counter, a USART, MSSP (SPI/I2C), Capture/Compare/PWM module, and a programmable Watchdog Timer with on-chip RC oscillator. What is a PIC16F-series 8-bit microcontroller? The PIC16F family is Microchip's mid-range 8-bit MCU portfolio that combines a RISC-style Harvard architecture (separate program and data buses) with FLASH program memory, addressing 14-bit instructions across 35 single-word opcodes. Microcontrollers like the PIC16F73 belong to the broader category of embedded microcontrollers -> RISC microcontrollers -> 8-bit microcontrollers -> integrated circuits, and they sit beneath digital signal processors and 32-bit Cortex-M MCUs in performance but above pure logic ICs in capability. This positioning explains why mid-range PIC devices dominate cost-sensitive embedded control applications. Key differentiating features include the Harvard bus architecture (allowing simultaneous instruction fetch and data access), self-programmable FLASH via ICSP (In-Circuit Serial Programming), ICD (In-Circuit Debugger) support, nanoWatt power management with multiple sleep modes, and configurable PORTA weak pull-ups. The 28-SSOP package measures approximately 10.2 mm x 5.3 mm x 1.75 mm with 0.65 mm pin pitch, suiting both hand-solderable prototyping and high-density production boards. The PIC16F73 is upward code-compatible with the PIC16C5X, PIC12CXXX, and PIC16C7X device families, enabling developers to reuse firmware across multiple product generations. Its Harvard architecture, 8-level hardware stack, and predictable interrupt response make it well-suited to deterministic control loops. Engineering trade-offs include the 8-bit data path (which constrains arithmetic throughput versus 16/32-bit MCUs) and the modest 192-byte RAM (which limits buffer sizes for complex protocol stacks). Typical applications include industrial sensor conditioning, motor control and PWM driver front-ends, battery chargers, consumer appliances, HVAC thermostats, security panel keypads, and automotive body controllers (with the appropriate AEC-Q100 qualified -I or -E variants). The PIC16F73 family is also widely deployed in legacy designs, hobbyist projects, and educational platforms due to its mature MPLAB X toolchain, free XC8 C compiler, and decades of community support. When designing with the PIC16F73T-E/SS, ensure the ICSP clock and data lines (RB6/RB7) have adequate isolation from switching nodes and that the MCLR reset pin is decoupled according to the datasheet to avoid spurious resets. The device's low-power nanoWatt sleep modes (down to sub-microamp quiescent current with the WDT disabled) make it well-matched to battery-powered designs where average duty cycle dominates battery life. This page synthesizes Microchip official datasheet values, distributor pricing context, drop-in alternatives within the same 28-SSOP footprint, and practical design considerations not collected in any single manufacturer document.

It delivers 20 MHz of processing throughput corresponding to a 200 ns instruction cycle, while integrating 7 KB of program FLASH (organized as 4K × 14 words), 192 bytes of RAM, and 22 digital I/O pins. The device supports an industrial operating voltage range of 2.5 V to 5.5 V. A microcontroller (MCU) is a programmable single-chip computer that integrates a CPU, memory, and peripherals onto a single silicon die. The PIC16F73 belongs to the PIC16F family of 8-bit RISC microcontrollers, which sits within the broader taxonomy of MCUs → embedded processors → semiconductors. The 'F' suffix denotes FLASH program memory, while the '16' indicates a 14-bit instruction width mid-range core with 35 single-word instructions and a simple register-based architecture that is upwards compatible with PIC16C5X, PIC12CXXX and PIC16C7X legacy parts. Key features of the PIC16F73T-I/ML include 5 channels of 8-bit Analog-to-Digital (A/D) conversion, three timers (Timer0, Timer1 and Timer2), a Universal Synchronous/Asynchronous Receiver Transmitter (USART) with a 9-bit addressable frame format, and a Master Synchronous Serial Port (MSSP) module supporting SPI and I2C. The device also integrates an 8-bit Parallel Slave Port on certain variants and provides power-managed modes for low-power applications. Architecturally, the PIC16F73 uses a Harvard-style RISC core with separate instruction and data buses, hardware stack, and a predictable single-cycle-per-instruction execution model that simplifies real-time control design. Its CMOS FLASH technology gives the MCU 100,000 erase/write cycle endurance with typical data retention in excess of 40 years, supporting field reprogrammability through ICSP. Typical applications for the PIC16F73T-I/ML include industrial control loops, sensor interfacing nodes, motor-drive front-ends, lighting controllers, automotive body electronics, consumer appliances, and remote-control units that need an industrial-temperature (-40 °C to +85 °C) MCU with on-chip ADC and USART. The compact 28-QFN (6 × 6 mm) footprint suits space-constrained designs such as handheld instruments. When designing with this part, pay attention to the decoupling network (a 0.1 µF ceramic capacitor close to VDD is essential), the ICSP programming pin assignments, and the choice of oscillator mode (HS, XT, LP, RC or INTIO) which directly affects current consumption. The exposed thermal pad must be soldered to a copper pour for mechanical and thermal reliability.

PIC16F73T-I/SS - 8-Bit 20MHz MCU 7KB Flash 28-SSOP

The Microchip PIC16F73T-I/SS is an 8-bit CMOS Flash microcontroller in the PIC16F family, featuring 7KB of program Flash memory, 192 bytes of RAM, and 22 digital I/O pins in a 28-pin SSOP package. It executes instructions at a 20MHz clock rate (200ns instruction cycle) and operates across 2.0V to 5.5V. The integrated peripherals include a 5-channel 8-bit ADC, two 8-bit timer/counters and one 16-bit timer/counter, a universal synchronous/asynchronous receiver-transmitter (USART), and a capture/compare/PWM (CCP) module. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and programmable I/O peripherals. The PIC16F73 belongs to Microchip's mid-range 8-bit PIC architecture, sitting between the baseline PIC10/12/16 family and the enhanced PIC18 family. Mid-range PIC MCUs use a 14-bit instruction word and 35 single-word instructions, with an 8-level hardware stack and a unified data/Flash memory map. They are widely adopted in cost-sensitive embedded designs that need deterministic real-time control, on-chip analog, and simple serial connectivity. Key features include 5 channels of 8-bit A/D conversion, an internal oscillator option for reduced BOM cost, an integrated USART for asynchronous/synchronous serial communication, and a CCP module for PWM or capture/compare timing. The Flash-based program memory supports in-circuit serial programming (ICSP), enabling in-system firmware updates without removing the part. Brown-out Reset (BOR) and Power-on Reset (POR) circuits protect against erratic supply conditions, and the Watchdog Timer (WDT) with on-chip oscillator improves system robustness. Architecturally, the device uses a Harvard architecture (separate program and data buses) implemented in CMOS with Microchip's nanoWatt power-management extensions. The Flash memory is rated for typically 100K erase/write cycles and 40 years of data retention. The peripheral feature set is tuned for embedded control rather than for high-throughput processing, which is why the part retains a small RAM and modest program-memory footprint. Typical applications include appliance controls, sensor signal conditioning, low-cost HVAC thermostats, lighting ballasts, automotive body modules (non-safety), battery chargers, and small industrial instrument front-ends. The combination of internal oscillator + 22 I/O + on-board ADC often eliminates external components, shrinking the bill of materials in volume production. When designing with this device, supply decoupling must be placed within 0.25 inch of VDD, and the MCLR reset line should be tied through a 10k pull-up to VDD unless driven by an external supervisor. The ICSP clock and data lines (RB6/RB7) must not be loaded with capacitance above the datasheet limit or in-circuit programming will fail.

Architecturally, the PIC16F74 uses CMOS FLASH process technology with Microchip's nanoWatt power-managed sleep modes and a wide 2.5V-5.5V operating range. A 14-bit instruction word delivers compact code density, while the integrated brown-out reset and watchdog timer improve robustness in industrial environments. The 44-PLCC package exposes most peripheral pins, simplifying PCB layout compared to smaller-pin PIC16F7x cousins. Typical applications for the PIC16F74-E/L include industrial control systems, HVAC fan/valve controllers, security alarm panels, motor-control signal conditioning, and embedded instrumentation with the 8-bit ADC reading sensor inputs. The extended temperature grade makes it suitable for outdoor or factory-floor equipment. When designing with the PIC16F74, ensure that your programmer/debugger supports the 5V FLASH programming algorithm (e.g., MPLAB ICD or PICkit) and that decoupling caps of 0.1uF plus bulk 1-10uF are placed close to VDD/VDD2. For low-power designs, leverage the nanoWatt sleep modes to draw sub-microamp standby currents between ADC bursts.

It features 7KB (4K x 14 words) of on-chip reprogrammable program memory, 192 bytes of RAM, and 33 digital I/O pins, with a maximum CPU clock rate of 20 MHz delivering up to 5 MIPS of instruction throughput. An 8-bit microcontroller (MCU) is a programmable computing IC that integrates a CPU, memory, and peripherals onto a single die. Within the MCU taxonomy the PIC16F74 belongs to the mid-range 14-bit instruction family (PIC16F), which sits above baseline 12-bit PIC10/12/12F parts and below the enhanced 16-bit PIC18 family. PIC16F mid-range devices target general-purpose embedded control in cost-sensitive industrial and consumer products where deterministic timing and low part count matter more than raw compute throughput. Key features include a 10-bit, 8-channel Analog-to-Digital Converter (ADC), two 8-bit timers with one 16-bit timer option, two Capture/Compare/PWM (CCP) modules, an SSP configurable as either 3-wire SPI or 2-wire I2C, a USART for asynchronous/synchronous serial, a parallel slave port, and nanoWatt power management with multiple sleep modes. The extended temperature grade (-40C to +125C) suits automotive under-hood, industrial, and outdoor installations. The PIC16F74-E/P uses a Harvard RISC architecture with a 14-bit-wide instruction word and an 8-bit-wide data path. Program execution is pipelined; instructions fetched in cycle N execute in cycle N+1, yielding near-1-MIPS-per-MHz efficiency. On-chip in-system self-programmable Flash allows field firmware updates via ICSP without removing the part from the board, while the ICD2/ICD3 debug interface supports breakpoint debugging through dedicated RB6/RB7 pins. Typical applications include industrial motor control, HVAC actuators, automotive body controllers, appliance controls (washing machines, dishwashers), uninterruptible power supplies (UPS), and instrumentation front-ends. The combination of 8-channel ADC, PWM, and USART makes it especially attractive for closed-loop control of small DC motors, solenoid drivers, and sensor-signal conditioning where single-chip integration reduces BOM. When designing with this device, remember that the parallel slave port shares pins with PORTD and PORTE, so using PSP mode forfeits those digital I/Os. Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the pin, and add a 10 uF bulk capacitor on AVDD if the ADC is used.

It integrates 7 KB of FLASH program memory (4K x 14 words), 192 bytes of RAM, and 33 digital I/O lines, with peripherals including an 8-channel 8-bit ADC, two 8-bit timers plus one 16-bit timer, two Capture/Compare/PWM (CCP) modules, a synchronous serial port configurable as SPI or I2C, and a USART. A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, and integrated peripherals. The PIC16F74 belongs to Microchip's mid-range PIC16 family, which sits between the baseline PIC10/12/16/17 devices and the high-performance PIC18 family in the broader 8-bit PIC taxonomy. Mid-range parts add features like hardware CCP modules, larger memory, and multi-channel ADCs while retaining the simple 35-instruction RISC architecture that made the PIC platform famous. This category is widely used in industrial control, consumer appliances, and automotive body/comfort electronics where deterministic real-time response and long-term firmware stability outweigh raw MIPS. Key differentiating specifications include the 20 MHz maximum clock input, 200 ns instruction cycle, 8-channel 8-bit ADC, two CCP modules, 33 I/O pins, and USART plus MSSP (SPI/I2C) communication. The I-grade part operates across the -40C to +85C industrial temperature range, which exceeds the E-grade (-40C to +125C) and commercial 0C to +70C variants. The TQFP-44 footprint is pin-compatible with several PIC16F7x family members, easing platform migration across memory sizes without PCB rework. The PIC16F74 uses a Harvard-architecture RISC core with separate program and data buses, which eliminates the fetch-decode bottleneck of Von Neumann designs and gives the deterministic 200 ns-per-instruction timing that real-time control loops depend on. Flash program memory supports in-circuit serial programming (ICSP) via two pins, allowing firmware updates in the field without removing the MCU from the board. The integrated brown-out reset, power-on reset, and watchdog timer reduce external component count and improve reliability in industrial environments. Typical applications include industrial control panels, motor control (BLDC/PMSM via the CCP+PWM outputs), HVAC fan and damper control, security alarm panels, smart card readers, instrumentation front-ends with ADC conditioning, and automotive interior/body modules. The USART plus MSSP combination supports simultaneous wired sensor bus and point-to-point or RS-232 links, while the 8-channel ADC handles multiple analog sensor inputs without an external multiplexer. When designing with this part, plan for an external 20 MHz crystal or resonator on OSC1/OSC2 (or use the internal 4 MHz RC oscillator to reduce BOM cost and PCB area). AVDD/AVSS must be tied to VDD/VSS even when the ADC is unused, and VREF+ should be sourced from a low-noise regulator if ADC accuracy below 8 LSB matters.

Operating at up to 20 MHz with a 200 ns instruction cycle, it integrates 14 channels of 10-bit Analog-to-Digital conversion, 3 timers, 3 Capture/Compare/PWM modules, a Master Synchronous Serial Port configurable for SPI or I²C, and a USART with LIN support. A microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, non-volatile program memory, and programmable I/O peripherals into one package. PIC microcontrollers sit within the broader category of microcontrollers -> embedded controllers -> semiconductor ICs, and the PIC16F family in particular targets cost-sensitive 8-bit applications where deterministic execution and low power consumption matter more than raw compute throughput. Key features include nanoWatt Technology for power-managed operation, an enhanced USART that supports RS-485, RS-232 and LIN 1.2, an ICD (In-Circuit Debug) interface, and an extended (-40 °C to +125 °C) operating temperature range denoted by the "/E" suffix. The device supports both internal and external oscillator modes and offers flash program memory that is self-programmable under firmware control. The PIC16F747 employs a Harvard RISC-style architecture with separate program and data buses, enabling a one-instruction-per-cycle execution model. Combined with a 35-word instruction set and 8-level hardware stack, the architecture is upwardly compatible with the PIC16C5X, PIC12CXXX and PIC16C7X families, simplifying migration paths from legacy code bases. Typical applications include industrial control nodes, automotive body and LIN sub-bus nodes, low-power sensor conditioning front-ends, and consumer appliance control boards where the 14-channel ADC and PWM-rich timer architecture replace several discrete analog components. Designers should pay attention to the ICSP/ICD pin sharing on RB6/RB7, the need for adequate decoupling on VDD/VSS, and the exposed pad electrical connection requirement of the 44-VQFN package for proper thermal dissipation.

PIC16F747-E/P

PIC16F747-E/P - 8-bit MCU 7KB Flash 20MHz 40-DIP | Microchip

The Microchip Technology PIC16F747-E/P is an 8-bit CMOS Flash-based PIC microcontroller (MCU) built on Microchip's enhanced mid-range architecture, delivering 7 KB of program Flash, 368 bytes of RAM, and 36 digital I/O pins in a 40-pin PDIP (DIP) through-hole package. The device executes instructions in a 200 ns cycle (5 MIPS at 20 MHz), offers 14 channels of 10-bit Analog-to-Digital conversion, three timers, three Capture/Compare/PWM modules, a Master Synchronous Serial Port configurable as either SPI or I2C, and a USART. A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, peripheral I/O, and clock generation - typically used as the embedded controller in larger electronic systems. The PIC16F747 belongs to the PIC16F mid-range family, which targets cost-sensitive embedded designs that require reliable I/O handling, ADC, and serial communication. The 'F' suffix denotes Flash program memory, allowing in-circuit reprogramming without an EPROM eraser. Key differentiating features include 14-channel 10-bit ADC with input multiplexing (versus only 8 channels on the lower-pin PIC16F73), three CCP/PWM channels for motor or lighting control, and a hardware USART alongside the MSSP for flexible master/slave serial links. The 20 MHz oscillator supports accurate baud-rate generation for industrial communication protocols. Typical applications include industrial control panels, HVAC and appliance controllers, motor-driver front-ends, sensor interface boards, and consumer product mainboards that need 14 analog inputs and three PWM outputs. The wide 2V-5.5V operating range simplifies battery and bus-powered designs. When designing with this device, allocate ADC channels carefully - the 14 inputs share pins with digital I/O, so enabling the ADC reduces usable GPIO. Place a 100 nF decoupling capacitor on each VDD/VDDCORE pin pair as close to the IC as possible. Programming uses ICSP via the PGD/PGC pins, which must be reserved on the PCB layout.

It belongs to the microcontroller family, which sits within embedded computing and is widely used where deterministic low-power control outweighs raw computational throughput. The PIC16F747 specifically targets cost-sensitive embedded designs that need rich analog and serial connectivity. The PIC16F747 integrates 14 channels of 10-bit Analog-to-Digital conversion (A/D), 3 timers, 3 Capture/Compare/PWM (CCP) modules, an MSSP configurable as either 3-wire SPI or 2-wire I2C, a USART, and nanoWatt Technology power management. Its 36 I/O pins are arranged for direct connection to mixed-signal peripherals, while the 368-byte RAM and integrated EEPROM make it suitable for applications requiring parameter retention. Architecture-wise, the PIC16F747 uses a RISC Harvard bus architecture with separate program and data paths, enabling single-cycle instruction fetch except for branch instructions. NanoWatt Technology provides dynamic power management through idle/sleep modes, supporting battery-backed applications. The 14-channel 10-bit ADC and 3 CCP modules enable simultaneous analog monitoring and PWM control, useful for motor control loops. Typical applications include industrial automation, consumer electronics, medical devices, motor control, and white-goods control panels. Its wide -40C to +125C operating range and 36 I/O count suit mixed-signal front-ends in industrial environments. Design consideration: when migrating from a 40-pin DIP PIC16F737 to the 44-TQFP PIC16F747, verify that the additional 4 pins are configured correctly (RB5-RB7 and RC0-RC3 mapping differ). Brown-out reset and watchdog timer configuration must be set in CONFIG words at programming time and are not field-upgradable.
