PIC16C716-20I/SO - 8-bit 20MHz OTP MCU, 18-SOIC | Microchip

The Microchip Technology PIC16C716-20I/SO is an 8-bit CMOS OTP (One-Time-Programmable) microcontroller in the PIC16 mid-range family, delivering 20 MHz operation (200 ns instruction cycle) in a 18-pin SOIC package. It integrates 3.5 KB of OTP program memory (2K x 14), 128 bytes of RAM, 13 digital I/O lines, two 8-bit timers plus one 16-bit timer, a 4-channel 8-bit Analog-to-Digital Converter, and a Capture/Compare/PWM (CCP) peripheral. An 8-bit PIC microcontroller is a RISC-based single-chip computer that executes one instruction per clock cycle (except branches) from a Harvard-architecture program store. The PIC16C716 belongs to the mid-range PIC16 sub-family, which sits between the baseline PIC10/12/16/17 families and the enhanced PIC18 family; it executes the standard 35-instruction mid-range set and is upwards compatible with the PIC16C5X and PIC12CXXX baseline devices. Its role in a system is to provide deterministic real-time control, on-chip A/D conversion, and PWM generation in compact, cost-sensitive designs. Key differentiating features include: 4 channels of 8-bit ADC (vs. 2-channel on the older PIC16C71), an integrated CCP module, two additional timers, and the OTP program memory that gives lower per-unit cost than Flash in high-volume production. The industrial -40C to +85C operating range (-I suffix) and 3.0V to 5.5V VDD tolerance suit factory-floor and appliance environments. Architecturally, the device uses Microchip's classic RISC core with a 14-bit instruction word, an 8-level hardware stack, and separate program/data buses (Harvard), which lets the CPU fetch the next instruction while reading data memory. The 8-bit ADC is successive-approximation with 8 input channels multiplexed, supporting single-channel conversions with software-selectable reference options. Typical applications include automotive body electronics, industrial sensor interfaces, white-goods and appliance control, IR remote receivers, and battery-charging controllers. The CCP module enables PWM-driven motor speed control and dimming, while the four ADC channels suit multi-sensor monitoring. When designing with the PIC16C716, note that OTP memory requires a windowed or one-time programming flow before solder; a Flash equivalent (PIC16F716) is recommended for prototypes and field-updatable firmware. Use Microchip's MPLAB X IDE with the XC8 C compiler and ICD debugging tools for development.

PIC16C716-20I/SS

PIC16C716-20I/SS - 8-Bit 20MHz MCU, 3.5KB OTP, 4-ch ADC | Microchip

The Microchip Technology PIC16C716-20I/SS is an 8-bit CMOS RISC microcontroller from the PIC® 16C family, offering 3.5KB (2K x 14) of One-Time-Programmable (OTP) program memory, 128 bytes of RAM, and 13 digital I/O pins in a 20-pin SSOP package. It executes instructions at a 20 MHz clock rate, delivering roughly 200 ns instruction cycles, with an operating voltage range tailored to 5V systems and an industrial temperature range of -40C to +85C. Background Knowledge: An 8-bit microcontroller (MCU) is a small, self-contained computing engine optimized for embedded control. The PIC16C family uses a Harvard-architecture RISC core with a small, deterministic instruction set, positioning it in the hierarchy: microcontroller -> 8-bit MCU -> PIC16C family -> CMOS RISC -> embedded processor -> semiconductor. PIC16C716 specifically adds on-chip analog (4-channel 8-bit ADC) and a Capture/Compare/PWM (CCP) peripheral, bridging pure digital logic and real-world analog signals. Key features of the PIC16C716-20I/SS include 4 channels of 8-bit Analog-to-Digital conversion, an enhanced Capture/Compare/PWM module for timing-critical applications, two additional timers (Timer0, Timer1, Timer2), a watchdog timer, and brown-out reset. The 13 I/O pins are 5V-tolerant and can source/sink up to 25 mA per pin, supporting direct LED drive and small-signal interface. The OTP program memory offers faster prototyping than masked-ROM parts but requires one-time programming before deployment. From an architectural perspective, the PIC16C716 uses a 14-bit instruction word and a 35-instruction set, allowing compact C and assembly code generation. The integrated ADC uses a successive-approximation register (SAR) topology with analog input multiplexing across 4 channels, eliminating external ADC ICs in many sensor-interface designs. The CCP module supports PWM frequency and duty-cycle control for motor, lighting, and power-conversion applications. Typical applications include automotive sensor conditioning, industrial appliance control (washing machines, HVAC), consumer device user interfaces, and motor-speed controllers. The combination of on-chip ADC and PWM in a single 20-pin footprint suits space-constrained designs that previously required multiple ICs. When designing with this part, ensure the OTP programming step is finalized before volume production, and budget for an external in-circuit serial programmer (ICSP) header. Decouple VDD with a 100 nF ceramic capacitor close to the pin, and respect the 25 mA per-pin and 200 mA package absolute maximums to avoid latch-up.

PIC16C716T-04E/SO - 4MHz 8-Bit OTP MCU 3.5KB | Microchip
PIC16C716T-04E/SO

PIC16C716T-04E/SO - 4MHz 8-Bit OTP MCU 3.5KB | Microchip

The Microchip Technology PIC16C716T-04E/SO is an 8-bit CMOS OTP microcontroller in the PIC16C family, featuring a 4MHz maximum oscillator frequency, 3.5KB (2K x 14) of One-Time Programmable (OTP) program memory, and 128 bytes of RAM, housed in an 18-pin SOIC package. It is engineered around Microchip's high-performance RISC architecture with only 35 single-word instructions and a 200ns instruction cycle at 20MHz, delivering deterministic throughput for embedded control loops. An 8-bit microcontroller is a single-chip computer that integrates a CPU, RAM, non-volatile program memory (ROM/EPROM/Flash/OTP), and I/O peripherals on one die. The PIC16C716 specifically targets low-cost, small-footprint embedded designs and belongs to the mid-range PIC16 family that sits above the baseline PIC12/PIC16C5X and below the PIC18 enhanced family. Its RISC core, fixed-width instruction set, and hardware stack make it popular for deterministic interrupt-driven applications such as motor control and sensor interfacing. Key features of the PIC16C716T-04E/SO include four channels of 8-bit Analog-to-Digital conversion, two 8-bit timers plus one 16-bit timer, a Capture/Compare/PWM (CCP) module, a Watchdog Timer with its own on-chip RC oscillator for reliable operation, and 13 digital I/O pins. The 04E speed grade denotes a 4MHz oscillator with the Extended (-40C to +125C) operating temperature range, while the -04E (4MHz) variant trades the higher speed for lower cost in applications that do not require 20MHz throughput. The 'T' suffix indicates Tape and Reel packaging, and 'SO' designates the 18-pin Small Outline IC. Typical applications span white goods and small appliance control, automotive interior modules, simple sensor signal conditioning, battery chargers, and low-cost consumer products where OTP is preferred for high-volume cost optimization. The 128-byte RAM, 3.5KB OTP, and 13 I/O lines fit well in designs that need A/D sensing plus basic PWM generation without a display interface. Compared to Flash-based PIC16F equivalents, the OTP PIC16C716T-04E/SO is typically priced lower at high volumes because the die does not include charge-pump erase circuitry. When designing with this device, allocate the OTP window carefully: code changes after programming are not possible, so verification via in-circuit emulation or a Flash equivalent (PIC16F716) is recommended during development. The 18-SOIC package is footprint-compatible with PIC16F716-I/SO, enabling a smooth transition from prototype to production. Power supply decoupling (0.1uF near VDD) and a stable oscillator layout are critical for ADC accuracy.

The Microchip PIC16C717-E/P is an 8-bit CMOS OTP-based PIC microcontroller running at 20MHz with 200ns instruction execution, housed in an 18-pin PDIP through-hole package. The extended (-E) temperature grade targets industrial and automotive applications requiring reliable operation across -40C to +125C. It integrates 3.5KB (2K x 14) of one-time-programmable program memory, 256 bytes of RAM, 6 channels of 10-bit A/D conversion, and a 16 I/O pin count. What is an 8-bit OTP microcontroller? OTP (One-Time Programmable) microcontrollers contain non-volatile program memory that can be written once and is then permanently retained, distinguishing them from flash-based MCUs that allow in-system reprogramming. The PIC16C717 sits in the hierarchy: microcontroller -> embedded MCU -> 8-bit MCU -> PIC mid-range MCU -> CMOS OTP MCU. This category suits cost-sensitive, fixed-function products where firmware is finalized at production and field updates are not required. Key differentiating features include 6 channels of 10-bit analog-to-digital conversion (versus fewer channels on older PIC16C5X and PIC12CXXX siblings), two additional timers, and a Capture/Compare/PWM (CCP) module for timing-critical applications. The device uses only 35 single-word instructions for code density and is upwards compatible with the PIC16C5X and PIC12CXXX instruction sets, enabling smooth migration paths from older designs. The PIC16C717 combines a RISC-based PIC core with on-chip peripherals including A/D, timers, PWM, and synchronous/asynchronous serial interfaces. The 200ns instruction cycle at 20MHz provides 5 MIPS throughput - sufficient for sensor sampling, motor control loops, and user-interface handling. OTP memory reduces die cost compared to flash, making this part attractive in cost-driven consumer and appliance designs. Typical applications include automotive body controllers and sensor interfaces, white-goods and small-appliance control boards, industrial instrumentation front-ends, and consumer-product embedded controllers. Its combination of analog input count and PWM output suits closed-loop control without external A/D chips. Designers should select the -E (extended) temperature grade explicitly for industrial or automotive environments; the standard PIC16C717-I/P serves commercial-temperature designs.

An 8-bit OTP microcontroller is a non-volatile programmable logic device whose program memory is written once (via windowed UV erase for ceramic-windowed variants) and retains its code without power. In the broader taxonomy: microcontroller -> embedded controller -> semiconductor. OTP parts sit between mask-ROM MCUs (cheapest, factory-programmed) and flash MCUs (re-programmable), and are common in cost-sensitive, low-volume, or production-locked applications where field upgrades are not required. The PIC16 mid-range family is one of the longest-lived 8-bit MCU architectures in production, with extensive tool and code heritage. Key features include 6 channels of 10-bit ADC (versus the 4 channels on the lower-cost PIC16C715), hardware PWM via the CCP module, brown-out reset (BOR) circuitry for reliable power-on behaviour, a watchdog timer, and an internal/external interrupt controller. The Harvard RISC architecture separates program and data buses, enabling deterministic instruction throughput. Typical applications include automotive sensor interfaces, white-goods and appliance control boards, industrial process control loops, battery chargers, and consumer-electronics front-panel controllers where 8-bit performance and on-chip A/D simplify the BOM. When designing with this part, note that OTP memory cannot be re-programmed in-circuit - the JW ceramic-windowed package variant must be used for prototyping or code development.

PIC16C717-I/SO - 8-Bit 20MHz OTP MCU, 3.5KB, 18-SOIC | Microchip

The Microchip Technology PIC16C717-I/SO is an 8-bit RISC microcontroller featuring the PIC16 CPU architecture, 3.5KB (2K x 14) of One-Time Programmable (OTP) program memory and 256 bytes of RAM, executing instructions in 200 nanoseconds at a 20 MHz clock. Housed in a surface-mount 18-pin SOIC (300 mil / 7.50 mm width), the device delivers 6 channels of 10-bit Analog-to-Digital conversion plus two timers and a Capture/Compare/PWM module, making it a strong fit for mixed-signal embedded designs. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, working RAM, I/O and peripheral blocks on one die. The PIC16C717 belongs to the PIC16 mid-range family, which sits between PIC10/12 baseline parts and PIC18 enhanced devices in the broader Microchip 8-bit portfolio. 8-bit MCUs continue to dominate high-volume cost-sensitive and real-time control applications because they offer deterministic instruction timing, low power draw and mature toolchains. OTP memory means the program is permanently fused by the user - one write per cell, no field re-programmability - which lowers unit cost versus flash parts in closed-production builds. Key specifications include 13 digital I/O pins, a 6-channel 10-bit ADC, two 8-bit timers (Timer0 with 8-bit prescaler, Timer2), a single Capture/Compare/PWM (CCP) module, and an internal Brown-out Reset (BOR) circuit. The supply voltage range is 4.0 V to 5.5 V (industrial), instruction cycle time is 200 ns at 20 MHz, and the part supports in-circuit serial programming via two pins. Total I/O count is 13 with one input-only pin (RA5). On-chip peripherals are mapped to PORTA and PORTC. Architecturally, the PIC16C717 uses a Harvard-style memory map with separate program (14-bit wide OTP) and data (8-bit SRAM) buses, a hardware stack of 8 levels, and direct/indirect addressing modes. Brown-out detection holds the part in reset when VDD dips below threshold, preventing code corruption. The 10-bit ADC uses successive approximation with analog input muxing across 6 channels - a generous count for the package size. Typical applications include automotive sensor signal conditioning, industrial appliance control (washing machines, HVAC fans), white-goods motor drive (CCP PWM for TRIAC or FET drive), consumer remote controls, and battery chargers. The 6 ADC channels suit multi-sensor monitoring (temperature, current, voltage) and the 20 MHz throughput supports 5 MIPS performance. When designing with the PIC16C717-I/SO, allocate ample board space for the SOIC-18 footprint and use decoupling capacitors of at least 100 nF ceramic plus 10 uF bulk near VDD. Because this is an OTP part, you must commit the program before final PCB assembly - reserve an ICSP header for prototype programming only. Validate timing margins for ADC acquisition at your chosen clock rate.

Key specifications include 20MHz maximum clock frequency, 16 digital I/O pins, six 10-bit ADC channels (versus four on the older PIC16C71), one 8-bit and one 16-bit timer plus a CCP module, an instruction set of 35 single-word instructions, an operating voltage range of 2.5V to 5.5V, and industrial temperature range operation from -40C to +85C. The device is offered in a 20-pin SSOP package with a width of 5.30mm suitable for space-constrained designs. The architecture features a 14-bit instruction word with an 8-bit data path, two stack levels for subroutine nesting, and reset circuitry including power-on reset and watchdog timer. The 10-bit ADC provides six input channels multiplexed onto a single sample-and-hold converter, allowing direct interface with analog sensors without external multiplexing. The CCP module supports capture, compare, and PWM modes for motor control and timing-critical applications. Typical applications include automotive body electronics, white goods and appliance control, industrial sensor interfaces, HVAC damper and valve actuation, and consumer products requiring multi-channel analog measurement. The combination of six ADC channels and CCP hardware makes the PIC16C717 especially suitable for three-phase BLDC motor control and multi-zone temperature sensing. When designing with this device, note that OTP memory cannot be re-programmed in the field - use the PIC16F717 flash variant during prototyping. Adequate decoupling with a 100nF ceramic capacitor close to VDD is mandatory, and the MCLR reset pin should be pulled high through a 10k resistor with an optional switch for manual reset.

PIC16C717/P - 8-bit OTP MCU, 20MHz, 3.5KB, 18-PDIP | Microchip

The Microchip Technology PIC16C717/P is a CMOS one-time-programmable (OTP) 8-bit PIC microcontroller built on Microchip's RISC-based PIC® architecture, delivering 200 ns instruction execution in an 18-pin PDIP package. It integrates 3.5 KB (2K x 14) of OTP program memory, 256 bytes of RAM, six 10-bit analog-to-digital converter (ADC) channels, two 8-bit timers, one capture/compare/PWM module, and a brown-out reset (BOR) circuit on a single die. The device operates from 4.0 V to 5.5 V at clock speeds up to 20 MHz. A PIC (Peripheral Interface Controller) is a Harvard-architecture 8-bit microcontroller family from Microchip that pairs a separate code and data bus with a small, deterministic RISC instruction set (35 single-word instructions in the PIC16C717). It belongs to the broader category of embedded microcontrollers within the microcontroller unit (MCU) hierarchy, and PIC16 devices sit between the baseline PIC10/12 families and the higher-pin-count PIC17/PIC18 families. PIC16C-series parts are OTP, meaning the program memory is written once at programming time, in contrast to PIC16F-series parts that use flash memory and allow in-circuit reprogramming. Key differentiating features include 13 usable I/O pins with individual direction control, on-chip POR/BOR/ILPW (brown-out detection) for robust power-on behavior, a wide operating temperature range of -40°C to +85°C (industrial), and a 35-instruction RISC core that simplifies firmware development in C or assembly. The instruction set is upwards compatible with the PIC16C5X and PIC12CXXX families, easing migration from older designs. The PIC16C717's 6-channel 10-bit ADC is the practical differentiator versus smaller PIC16 parts - it lets the MCU read multiple analog inputs simultaneously, which is why Microchip positions it for sophisticated automotive, industrial, appliance, and consumer applications where multi-channel sensing matters. Its architecture uses a 14-bit-wide program memory word and an 8-bit data path, with a 14-bit instruction encoding and 8-level hardware stack for subroutine nesting. Typical applications include multi-channel sensor conditioning (temperature, pressure, light), small motor and fan control with PWM, automotive body electronics, white-goods control boards, and consumer appliance user interfaces that mix analog sensing with digital I/O. The wide 4.0-5.5 V supply range lets it operate directly from regulated 5 V rails. When designing with the PIC16C717/P, note that OTP memory cannot be erased - prototypes should be built on PIC16F-series equivalents (e.g. PIC16F716) and migrated to PIC16C717 for production cost optimization. Decoupling the VDD pin with 0.1 µF and bulk 10 µF+ capacitors is essential to keep ADC readings stable and to avoid spurious BOR resets.

PIC16C717/SO - 8-Bit 20MHz OTP MCU, 3.5KB | Microchip

The Microchip Technology PIC16C717/SO is an 8-bit CMOS OTP-based microcontroller built on the PIC16C architecture, housed in an 18-pin SOIC package with 3.5KB (2K x 14) of program memory and operating at up to 20MHz clock speed (200 ns instruction cycle). The device integrates 6 channels of 10-bit Analog-to-Digital (A/D) converter, two additional timers (Timer1 and Timer2), a Capture/Compare/PWM (CCP) module, 13 I/O pins, Brown-out Reset (BOR), and a programmable watchdog timer. An OTP (One-Time Programmable) microcontroller is a non-volatile programmable logic device that can be written to exactly once using a programming voltage; it cannot be erased or re-programmed. OTP MCUs occupy the middle ground between mask-ROM parts (cheapest at high volume, no field programmability) and Flash MCUs (re-programmable many times). For low-to-medium volume production runs where firmware is stable but volumes do not justify mask-ROM tooling, OTP provides the lowest unit cost. The PIC16C717/SO fits this profile in automotive, industrial, appliance, and consumer applications where code is fixed at production time. Key features include the 10-bit 6-channel ADC for sensor interfacing, hardware PWM via the CCP module for motor or LED control, an enhanced USART (SCI) for asynchronous serial communication, an I2C/SPI capable synchronous serial port (SSP), and 368 bytes of RAM. The PIC16C717 also features a wide operating voltage range and low-power SLEEP mode typical of the PIC mid-range family, alongside code-protection and oscillator-start-up timer circuitry. Typical applications include automotive body controllers and HVAC actuators, white-goods and appliance motor control boards, industrial sensor conditioning and front-end controllers, and consumer product keypads or remote-control subsystems. The 10-bit ADC and hardware PWM combination in an 18-pin footprint is well suited to closed-loop control tasks. When designing with the PIC16C717/SO, ensure the OTP programming step is integrated into the production line: no firmware revisions are possible after programming. Also evaluate the newer PIC16F family (Flash-based) for prototypes and early production; switch to PIC16C717/SO only once firmware is frozen and volumes justify the OTP cost advantage.

A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and configurable peripheral blocks. PIC microcontrollers from Microchip use a Harvard architecture with separate program and data buses and a RISC-style instruction set, which enables deterministic instruction timing (one instruction per instruction cycle, four clock cycles per cycle on standard PIC16 parts). Within the broader semiconductor taxonomy, the PIC16C717 belongs to the 8-bit MCU family, which sits below 16-bit and 32-bit MCU families in complexity but dominates cost-sensitive and low-power embedded applications. The PIC16C717 features 200 ns instruction execution, only 35 single-word instructions, an operating voltage range of 2.5 V to 5.5 V (industrial -I variant), and brown-out reset (BOR) circuitry for reliable system startup. Its six 10-bit ADC channels make it well suited to sensor-rich designs, while the CCP module delivers PWM generation for motor, lighting, or power control. The /SS suffix denotes the 20-pin SSOP package, which trades the pin count of the 28-pin variants for a smaller PCB footprint. Typical applications include automotive sensor signal conditioning, industrial process control, appliance control boards, and consumer products requiring on-board analog measurement. The 6-channel ADC is especially useful in designs that monitor multiple analog signals (temperature, pressure, current, voltage) without needing an external ADC. Because the part uses One-Time-Programmable (OTP) memory, it is well matched to high-volume production where firmware is finalized before the device is shipped to the line. When designing with this device, ensure that your firmware is fully validated before programming, since OTP memory cannot be re-written. For prototype and low-volume runs, consider migrating to the flash-based PIC16F717 (pin-compatible) which supports in-circuit reprogramming. The PIC16C717/SS is also a useful target when long-term retention and code security outweigh the convenience of flash memory in flash-based projects.

It supports in-circuit serial programming (ICSP) for OTP devices, and offers 16 I/O pins across two ports. The brown-out detector protects data integrity during supply dips, while the power-on reset (POR) ensures deterministic start-up behaviour without external components. Architecturally, the device uses a RISC instruction set with only 35 single-word instructions, enabling compact code density and fast context-switching. The 8-bit ALU is paired with a 14-bit instruction word, giving most instructions single-cycle execution except branches (two cycles).

The device executes one instruction per 200 ns cycle from a 35-instruction RISC core. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory and peripherals; the PIC16C717 specifically belongs to the PIC16C sub-family of Microchip's 8-bit PIC architecture, sitting between the baseline PIC12C/PIC16C5X devices and the more capable PIC17C/PIC18C families. Its mid-tier feature set targets low-cost embedded control where ROM reprogramming is not required after deployment, such as appliance controllers and disposable sensor modules. The PIC16C717's headline feature is a 10-bit A/D converter providing 6 analog input channels, paired with two additional timers beyond the baseline Timer0. This ADC resolution is the same as found on many PIC16F flash parts and enables direct interface to analog sensors (temperature, light, voltage) without an external ADC IC. OTP program memory means the firmware is permanently written during production programming and cannot be field-updated - this is the key differentiator versus flash-based PIC16F variants such as the PIC16F690. Typical applications include white-goods motor control boards, low-end remote controls, battery chargers with analog feedback, and industrial sensor interfaces. The 20 MHz clock speed and 10-bit ADC make it well-suited to closed-loop control tasks where computational throughput is moderate but analog precision is required. When designing with the PIC16C717, remember that OTP parts are not erasable; firmware bugs cannot be fixed in-circuit. Choose the flash variant (PIC16F717) if in-field firmware updates are required.

A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory, working RAM, peripheral set, and I/O on one die. The PIC16C71 sits in the PIC16CXX mid-range family, which uses a 14-bit instruction word and a 35-instruction RISC core; its hypernym hierarchy is microcontroller -> embedded processor -> digital IC -> semiconductor. The 'C' suffix indicates EPROM/OTP program memory (non-volatile, one-time programmable in windowless package, UV-erasable in CERDIP windowed variants). Key differentiating specifications include: 1.75 KB EPROM program memory, 36 B RAM, 13 I/O, four-channel 8-bit ADC, Timer0 (8-bit timer/counter with 8-bit prescaler), brown-out reset (BOR), watchdog timer, and 4 MHz clock speed. With BOR active, the part guarantees a clean reset when VDD falls below the BOR threshold, eliminating corrupted startup states on brown-out events. The RISC core executes most instructions in one oscillator cycle, giving ~1 MIPS at 4 MHz. Typical applications include industrial control loops, sensor signal conditioning, automotive body controllers (non-safety), low-cost consumer appliances, and educational/embedded learning kits. The on-chip ADC is well-matched to bridge-sensor, thermistor, and potentiometer front-ends without requiring an external ADC. When designing with this part, ensure that the program memory is sized for OTP programming flow before committing to PCB layout. Engineers migrating to a Flash-based PIC should consider the PIC16F71 as a drop-in upgrade with same peripheral set and pinout.

PIC16C71T-20I/SO - 8-Bit 20MHz OTP MCU w/ ADC | Microchip

The Microchip Technology PIC16C71T-20I/SO is an OTP (One-Time Programmable) 8-bit CMOS microcontroller from the PIC16CXX mid-range family, operating at up to 20 MHz with 1.75 KB (1K x 14) of program memory and 36 bytes of RAM, housed in an 18-pin SOIC (0.295 inch / 7.50 mm width) package supplied on tape and reel. It integrates a 5V-tolerant architecture and on-chip A/D converter peripherals, targeting low-cost embedded applications. An 8-bit microcontroller (MCU) is a small computer-on-a-chip containing a CPU, memory, and peripherals. The PIC16C71 belongs to the mid-range PIC family, sitting between baseline (PIC10/12/16) and enhanced mid-range (PIC16F1xxx) tiers. As a ROM/OTP device, it is programmed once and is typically chosen for cost-sensitive, high-volume products where code is fixed for the lifetime of the unit. Key features include a 20 MHz maximum clock, 1.75 KB OTP program memory, 36 bytes of data RAM, an integrated 8-bit 4-channel analog-to-digital converter, 13 I/O pins, and a wide 3.0V to 6.0V operating voltage range. The 'T' suffix denotes tape-and-reel packaging, '20' indicates the 20 MHz speed grade, 'I' marks the industrial -40C to +85C temperature grade, and 'SO' specifies the 18-pin SOIC package. The device uses a Harvard architecture with separate program and data buses, RISC instruction set (35 instructions), and a 14-bit instruction word. The integrated ADC supports direct analog sensor interfacing without external components, while the industrial temperature range and CMOS low-power design suit it for unattended, battery-tolerant environments. Typical applications include low-cost consumer appliances, sensor signal conditioning nodes, industrial control sub-modules, automotive body-fitting interior subsystems, and battery-powered instrumentation. The integrated ADC simplifies analog sensor reading while the small 18-pin footprint aids compact PCB layouts. When designing with the PIC16C71T-20I/SO, note that this is an OTP part - code cannot be re-programmed in-circuit. For prototyping, use the windowed JW version, and for production with firmware upgrades, consider a Flash-based equivalent such as PIC16F716. This page consolidates distributor inventory, drop-in PIC16C71T-20I/SO cross-references, and design-in guidance not aggregated in the original Microchip datasheet, helping engineers compare substitutes and source the part quickly.

PIC16C72-04/SO

PIC16C72-04/SO - 4MHz 8-Bit OTP MCU 28-SOIC | Microchip

The Microchip Technology PIC16C72-04/SO is an 8-bit RISC microcontroller from the PIC16C7X mid-range family, featuring a 4 MHz maximum clock speed, 3.5 KB (2K x 14) of One-Time-Programmable (OTP) program memory, and 128 bytes of on-chip data RAM, all housed in a 28-pin SOIC (SO) wide-body package. This CMOS, fully-static device integrates a multichannel 8-bit analog-to-digital converter, 22 I/O pins, 13 selectable I/O channels, a PWM output, and brown-out reset (BOR) circuitry, plus an 8-bit Timer0 with 8-bit prescaler. An 8-bit microcontroller (MCU) is a small computer-on-a-chip that combines a CPU, RAM, ROM/Flash/OTP program memory, and peripherals on a single die. Microcontrollers sit within the embedded systems hierarchy: MCU -> embedded processor -> semiconductor -> integrated circuit. The PIC16C7X family targets cost-sensitive embedded control applications, while the OTP memory variant (PIC16Cxx) is intended for low-volume production and prototype builds where in-circuit reprogrammability is not required. Key features of the PIC16C72-04/SO include 35 single-word instructions (most executed in one instruction cycle, except program branches at two cycles), 200 ns instruction cycle at 20 MHz (4 MHz in this -04 speed grade), parallel slave programming via a boot loader, and an operating voltage range of 4.0 V to 5.5 V. The mid-range PIC16CXX core provides deterministic instruction timing and bit-manipulation primitives optimized for control loops. Architecturally, the PIC16C72-04/SO uses a Harvard-style architecture with separate program and data buses, enabling simultaneous instruction fetch and data access. The integrated 8-bit ADC and PWM module support closed-loop motor and analog-sensor interfaces, while the BOR and watchdog timer (WDT) enhance field reliability against brown-out and software-stuck conditions. Typical applications include consumer appliance control, HVAC thermostat logic, simple motor-control boards, low-end sensor signal conditioning with ADC, and industrial automation front-ends. Engineers should note that Microchip flags the PIC16C72 family as having a newer revision available: consider the PIC16C72A (compatible drop-in) or PIC16F72 (flash-based reprogrammable successor) for new designs. When designing with this part, ensure Vdd stays within 4.0 V to 5.5 V and respect the wide-body SOIC-28 PCB land pattern (300 mil body width). OTP parts cannot be erased - design firmware to be fully validated before final programming. This page synthesizes real-time distributor pricing, drop-in alternatives (PIC16C72A, PIC16F72), and practical OTP-MCU design notes not found on the bare manufacturer datasheet, helping engineers select, source, and lay out the part with confidence.
