PIC16C712T-20/SS - 8-Bit 20MHz OTP MCU, 1.75KB | Microchip

The Microchip Technology PIC16C712T-20/SS is an 8-bit CMOS OTP (One-Time Programmable) RISC microcontroller from the PIC® 16C family, delivering 20 MIPS performance at 20 MHz in a 20-pin SSOP package. It integrates 1.75 KB of program memory (1K x 14) and 128 bytes of RAM, with 4-channel 8-bit Analog-to-Digital conversion, a Capture/Compare/PWM module, and the standard 35-instruction PIC16C core for compact embedded control code. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripheral interfaces onto one die. The PIC16C712 belongs to the PIC® 16C family of 8-bit RISC microcontrollers, which sit within the broader taxonomy of microcontrollers -> embedded processors -> semiconductor ICs. OTP-based PIC MCUs are programmed once via a device programmer and retain their code without external memory, making them ideal for fixed-function commercial and industrial products where flash reprogrammability is not required. Key features include 200 ns instruction execution time, 13 I/O pins, two 8-bit timers plus one 16-bit timer, watchdog timer with on-chip RC oscillator, power-on reset, brown-out detect, and in-circuit serial programming (ICSP) capability. The 8-bit ADC with 4 input channels supports 8-bit resolution suitable for basic sensor monitoring and potentiometer feedback applications. The architecture uses a Harvard-style 14-bit instruction word with separate program and data buses, enabling deterministic single-cycle instruction execution. The 20-pin SSOP footprint is optimized for space-constrained applications where PCB area matters more than wide peripheral count. Typical applications include consumer appliance control, HVAC thermostats, small motor control, battery chargers, security sensor interfaces, and low-cost industrial control modules. The OTP memory model suits high-volume fixed-code products where unit cost dominates over field upgradability. When designing with this device, ensure the 5V supply rail is stable because the OTP version does not support ISP flash reprogramming in-circuit. Plan code carefully before burning the part, and always order production quantities with a margin for code-revision rework.

PIC16C712T-20E/SO - 8-Bit 20MHz OTP MCU, 1.75KB | Microchip
PIC16C712T-20E/SO

PIC16C712T-20E/SO - 8-Bit 20MHz OTP MCU, 1.75KB | Microchip

The Microchip Technology PIC16C712T-20E/SO is a 8-bit CMOS OTP microcontroller in the PIC16C family, delivering 20MHz (200ns instruction cycle) performance with 1.75KB (1K x 14) of one-time-programmable program memory, 128 bytes of RAM, and 13 general-purpose I/O pins, all housed in an 18-pin SOIC (SO) package with 7.50mm body width. The "T" suffix indicates tape-and-reel packaging, the "20" denotes the 20MHz maximum clock, the "E" designates the extended industrial temperature grade (-40C to +125C), and "/SO" specifies the SOIC-18 surface-mount package. What is an OTP microcontroller? An OTP (One-Time Programmable) microcontroller is a type of embedded computing device whose program memory can be written only once after manufacture, using a programmable ROM cell that is permanently altered (typically by blowing a fuse or antifuse) during device programming. OTP MCUs occupy a middle ground between mask-ROM parts (cheapest at high volume but require factory commitment) and flash-based MCUs (reprogrammable in-circuit but slightly more expensive per unit). They are favored in cost-sensitive, high-volume, mature products where firmware has stabilized and field updates are not required, such as appliance controllers, simple sensor interfaces, and consumer toys. The PIC16C712T-20E/SO integrates a 4-channel 8-bit Analog-to-Digital converter with 2 additional timers (Timer0, Timer1, and Timer2 plus a Capture/Compare/PWM module), enabling mixed-signal embedded designs in a single chip. The 35 single-word instruction RISC architecture simplifies code development, while upward compatibility with PIC16C5X and PIC12CXXX allows firmware migration from older PIC designs. The 18-pin SOIC form factor suits through-hole-free, surface-mount assembly and supports the operating voltage range of 4.0V to 5.5V. Typical applications include appliance control boards, low-cost motor control loops via the CCP module, simple sensor interface front-ends, hobbyist and educational projects, and legacy industrial controller retrofits. The extended temperature range makes the "E" suffix variant suitable for under-hood automotive subsystems and outdoor industrial installations. A key design consideration when selecting an OTP MCU is field-serviceability: once programmed, the device cannot be firmware-updated, so designers must provision programming test pads or sockets in production. Also note that the PIC16C712 series is in mature/legacy status with Microchip, so the PIC16F877A or PIC16F18855 flash-based equivalents are typically preferred for new designs.

The "T" in the part number indicates tape-and-reel packaging, and "20" specifies the 20 MHz maximum clock speed. The "SS" suffix designates the 20-pin SSOP package. Architecturally, the PIC16C712T uses an enhanced PIC16C5X core with 14-bit instruction words, dual 8-bit timer/counters (Timer0 with 8-bit prescaler, Timer1 with 16-bit operation), and a 4-channel 8-bit ADC with selectable reference voltages. The CCP module supports 10-bit PWM resolution, enabling motor control, LED dimming, and signal generation applications. Typical applications include appliance control, automotive subsystems (non-safety-critical), industrial sensor interfaces, low-end motor control, and white goods. The wide operating temperature range also makes it suitable for outdoor and harsh-environment embedded designs. When designing with this MCU, ensure oscillator selection matches the application's clock-accuracy requirements: external clock mode supports crystal or resonator operation up to 20 MHz, and unused I/O pins should be configured as outputs to minimize power consumption.

A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (ROM/Flash/OTP), working RAM, and a rich set of peripheral blocks (I/O ports, timers, ADC, communications) onto one die. The PIC16C family uses a Harvard RISC core with a small, deterministic instruction set, allowing most instructions to execute in a single oscillator cycle (4 clocks). Within the broader taxonomy, an 8-bit MCU sits below 16-bit and 32-bit controllers in computational throughput but excels in low cost, low power, and deterministic interrupt response, making it the workhorse of cost-sensitive embedded designs. Key features of the PIC16C712 include an integrated 4-channel, 8-bit Analog-to-Digital Converter (ADC), a 13-bit I/O count across two ports (PORTA and PORTB), a watchdog timer with on-chip RC oscillator, a programmable code-protection mechanism, and an operating voltage range of 2.5 V to 6.0 V (typical 5 V). The 'T' suffix denotes tape-and-reel packaging, '20' indicates the 20 MHz speed grade, and 'I' marks the -40C to +85C industrial temperature range. From an architectural standpoint, the device has a 14-bit instruction word, a 35-instruction set, two 8-bit timer/counters (Timer0, Timer2) plus a 16-bit timer (Timer1), and a 5-channel 8-bit ADC with selectable reference voltages. The 18-pin SOIC package supports through-hole-free assembly and is one of the most widely used footprints for cost-sensitive consumer, industrial, and appliance applications. Typical applications include motor control (small DC and stepper drivers), battery chargers and smart power management, small appliances (coffee makers, hand tools), automotive body controllers (non-safety subsystems), and general-purpose sensor-interface boards. The on-chip ADC allows direct connection to potentiometers, thermistors, and low-bandwidth analog sensors without an external converter. When designing with this part, note that OTP memory cannot be reprogrammed in-circuit; for prototypes choose a windowed (JW) or Flash-based PIC16F equivalent. Also confirm oscillator configuration (RC, XT, HS, LP) matches the crystal or resonator in use, and respect the 20 MHz VDD-dependent limit to avoid timing violations in high-Vdd designs. This page synthesizes distributor pricing, package-level alternatives, and design notes specific to the PIC16C712 SOIC-18 footprint, going beyond the manufacturer datasheet to add selection guidance for engineers evaluating cross-brand 8-bit MCU replacements.

The Microchip Technology PIC16C715-04/SO is an 8-bit RISC microcontroller from the PIC16C71X mid-range family, featuring a 4 MHz maximum clock frequency, 3.5KB (2K x 14) of One-Time-Programmable (OTP) program memory, and 128 bytes of on-chip data RAM, all housed in an 18-pin SOIC (SO) package. The device integrates 4 channels of 8-bit Analog-to-Digital (A/D) conversion, a Timer0 8-bit timer/counter with 8-bit prescaler, and 13 bidirectional I/O lines supporting direct LED drive and basic digital interfacing. Operating from a 4.0V to 5.5V single supply, the PIC16C715-04/SO is built on CMOS technology and includes Brown-out Reset (BOR) circuitry for reliable startup under unstable power conditions. An 8-bit microcontroller is a programmable logic device that executes instructions fetched from on-chip program memory using an internal CPU core, with a data path width of 8 bits. Microcontrollers sit within the broader hierarchy of: microcontroller -> microprocessor with integrated peripherals -> embedded computing IC -> semiconductor device. The PIC16C715 belongs to the mid-range PIC16C family, which uses a 14-bit instruction word and Harvard architecture (separate program and data buses), enabling deterministic instruction timing that simplifies real-time control firmware development. Key differentiating features include integrated 8-bit A/D conversion (4 channels) eliminating the need for external ADC ICs in low-resolution analog signal acquisition, hardware Brown-out Reset that prevents code execution at unsafe VDD levels, and a wide commercial operating temperature range suitable for consumer and industrial environments. The OTP program memory allows low-cost, low-volume programming during development or pilot production runs. Architecturally, the PIC16C715 uses a RISC-style instruction set with most instructions executing in a single instruction cycle (4 clock periods), giving an effective throughput of 1 MIPS at 4 MHz.

PIC16C715-04E/P

PIC16C715-04E/P - 8-bit CMOS MCU, 4MHz, 3.5KB EPROM | Microchip

The Microchip Technology PIC16C715-04E/P is an 8-bit CMOS RISC microcontroller from the PIC16C7X mid-range family, integrating a 4-channel 8-bit A/D converter, 3.5KB EPROM program memory, and 128 bytes of RAM in an 18-pin PDIP (P) through-hole package. It executes instructions in a 200 ns cycle at 4 MHz oscillator input, supports 35 single-word instructions, and operates from a single 4.0 V to 5.5 V supply. An 8-bit microcontroller is a single-chip computer with an 8-bit data path, ALU, registers, program memory, and integrated peripherals. The PIC16C7X family sits in the PIC mid-range hierarchy - more capable than the baseline PIC16C5X/PIC12CXXX but below the PIC17C/PIC18 enhanced families. The PIC16C715 specifically adds an integrated multi-channel ADC and Brown-out Reset (BOR) circuitry, positioning it as a compact analog-friendly MCU. Key features include 13 bidirectional digital I/O pins with individual direction control, an 8-bit Timer0 with an 8-bit programmable prescaler, 4-channel 8-bit A/D converter, on-chip Brown-out Reset (BOR), Power-on Reset (POR), and a Watchdog Timer (WDT) with its own on-chip RC oscillator. The device is fully static CMOS, OTP-based, and offers upward code compatibility with PIC16C5X and PIC12CXXX devices, easing migration. Architecturally, the PIC16C715 uses a Harvard-style separate program and data bus design with a 14-bit instruction word, two-stack hardware stack (PIC16C71X class), and direct/indirect addressing modes. The internal oscillator support and low-power CMOS design suit battery and line-powered embedded applications. BOR and POR ensure defined startup and brown-out recovery, critical for industrial and automotive-grade embedded designs. Typical applications include industrial sensor signal conditioning, low-cost motor control interfaces, automotive body and sensor electronics, appliance control boards, and embedded measurement instruments. The 18-pin PDIP form factor remains popular for through-hole prototyping, educational platforms, and legacy industrial retrofits where surface-mount is impractical. When designing with this MCU, observe the 5.5 V absolute maximum supply and ensure the EPROM programming voltage is correctly sequenced during in-circuit or in-socket programming. For new designs, Microchip recommends the pin-compatible PIC16F716 (Flash-based successor) as a forward migration path with the same 18-pin DIP footprint but in-system programmability.

PIC16C715-04E/SO

PIC16C715-04E/SO - 8-bit OTP MCU 4MHz 3.5KB EPROM | Microchip

The Microchip Technology PIC16C715-04E/SO is an 8-bit CMOS RISC OTP microcontroller with an integrated 8-bit multichannel A/D converter, packaged in an 18-pin SOIC (SO) outline rated for the automotive temperature grade. According to the manufacturer datasheet, the device operates at 4 MHz clock speed from a 4.0 V to 5.5 V supply, integrates 3.5 KB (2K x 14) of EPROM program memory and 128 bytes of data RAM, and exposes 13 individually-direction-controlled I/O pins. Brown-out Reset (BOR), an 8-bit Timer0 with 8-bit prescaler, a Watchdog Timer, and a 4-channel 8-bit ADC round out the on-chip peripherals, making it a self-contained compute-and-sense node for embedded products. Background knowledge: an 8-bit microcontroller is a single-chip computer built around an 8-bit data path and a Harvard program/data memory architecture. Within that hierarchy, the PIC16C715 belongs to the PIC16C mid-range family of OTP (one-time-programmable) EPROM-based MCUs, sitting between the PIC16C711 (no ADC variant, but smaller pin-out) and the flash-based PIC16F716 superset recommended by Microchip. OTP EPROM MCUs are typically chosen for low-to-medium volume products where the BOM cost advantage of EPROM outweighs the field-reprogrammability of flash. The '-04E' suffix denotes the 4 MHz speed grade with the extended (-40C to +125C) automotive temperature range, and the '/SO' suffix designates the 18-lead small-outline (SOIC-18) gull-wing surface-mount package. Key features highlight the system's ability to deliver analog sensing plus digital control from a 4-5.5 V rail, with 13 GPIO that can each be tri-stated, an 8-bit ADC with four input channels multiplexed from PORTA, and brown-out detection that holds the part in reset until VDD is stable. The CMOS process plus the RISC core delivers 200 ns single-cycle instruction execution, so an interrupt service routine or ADC polling loop can run inside the headroom of most 1 ms control loops. Power-saving SLEEP mode and a Watchdog Timer with its own on-chip RC oscillator are included, so the part can survive brown-outs and soak out without external supervisor hardware. Technical depth: the device uses a 14-bit-wide instruction word aligned to the 2K-word EPROM array, which yields 3.5 KB of program memory. The 8-bit data bus is separate (Harvard architecture), so instruction fetch and data access occur in parallel, removing fetch stalls common to von-Neumann 8051-class parts. The brown-out trip threshold is internally trimmed to approximately 4.0 V, and the part exits reset only after VDD rises above that level, eliminating the need for an external reset supervisor in many designs. Typical applications include automotive body controllers and sensor interfaces, HVAC damper and valve control, white-goods user-interface boards, industrial sensor-transmitter front-ends, battery-powered instrumentation with sleep/wake duty cycling, and retrofits of older PIC16C71X boards to the wider-temperature grade. The 4-channel ADC combined with 13 GPIO lets one PIC16C715 replace a discrete analog front-end plus a small MCU on a 1-square-inch PCB. Design consideration: the EPROM cell windowless package does not allow in-circuit reprogramming; firmware is locked at the time of program and cannot be field-updated. Engineers who anticipate firmware revisions should instead migrate to the pin-compatible flash part PIC16F716 (recommended by Microchip) or, where automotive-grade is required, to PIC16F716-I/SO.

It integrates 3.5KB (2K x 14) of one-time-programmable program memory, 128 bytes of RAM, 13 digital I/O pins, and a 4-channel 8-bit analog-to-digital converter. What is an 8-bit microcontroller? An 8-bit MCU is a single-chip computer with an 8-bit data path that executes one instruction per cycle and integrates CPU, RAM, non-volatile program memory, and peripherals. The PIC16C715 belongs to the mid-range PIC16C family and inherits the RISC-based PIC architecture, executing instructions in 200ns at 4MHz. As an OTP part, it is intended for volume production where field firmware updates are not required. Key features include 35 single-word instructions, 8-bit timer/counter with 8-bit prescaler, 4-channel 8-bit ADC, brown-out reset (BOR), power-on reset (POR), and a watchdog timer (WDT). The 13 I/O pins each have individually programmable direction control, and the device supports in-circuit serial programming via the ICSP interface. The PIC architecture is upwards compatible with the PIC16C5X baseline and PIC12CXXX devices, simplifying code migration across the family. The PIC16C715 is built on a CMOS process and operates over the industrial temperature range of -40C to +85C as indicated by the /I designator. It is recommended by Microchip as a legacy successor part for designs previously using the PIC16C71X series; the newer flash-based PIC16F716 is suggested as an upgrade path for new designs. Typical applications include industrial control nodes, appliance controllers, automotive body electronics (where OTP cost advantage matters), consumer products with simple A/D sensing, and educational or hobby microcontroller projects. The 4-channel ADC enables direct interfacing with analog sensors (temperature, light, potentiometers). Designers should consider the OTP limitation (no field re-programming) and plan to use PIC16F716-I/P or similar flash parts if firmware iteration is required. The 18-PDIP package remains a strong choice for through-hole prototyping, breadboarding, and educational kits because it is easy to handle and socket-compatible with most PIC16C71X variants.

PIC16C715-20/P

PIC16C715-20/P - 8-bit OTP MCU, 20MHz, 3.5KB, 13 I/O, A/D | Microchip

The Microchip PIC16C715-20/P is a low-cost, high-performance, fully-static, 8-bit CMOS microcontroller from the PIC16CXX mid-range family, integrating a 4-channel 8-bit Analog-to-Digital converter and packaged in an 18-pin PDIP (through-hole). It executes instructions in 200 ns at a 20 MHz oscillator, programs with only 35 single-word instructions, and is built on Microchip's advanced RISC architecture with an eight-level deep hardware stack and multiple internal/external interrupt sources. The OTP program memory holds 3.5 KB (2K x 14 words), the data SRAM is 128 bytes, and 13 digital I/O pins are available for general-purpose use. An 8-bit microcontroller is a single-chip computer that integrates a CPU, memory (ROM/RAM), and peripherals onto one die; the PIC mid-range family extends this concept with a RISC Harvard architecture where program and data buses are physically separated, allowing simultaneous instruction fetch plus data access for deterministic, predictable execution. PIC microcontrollers remain a foundational part of the broader 8-bit MCU market (a sub-category of microcontrollers, which themselves belong to integrated circuits / embedded computing) and are widely deployed in cost-sensitive embedded applications. Key features of the PIC16C715-20/P include 4 channels of 8-bit A/D conversion (making it ideal for sensor reading applications), a 20 MHz maximum operating frequency, 8-bit data path width, on-chip oscillator support (with optional external crystal/resonator), and a wide operating voltage range supporting both 3.0V and 5.0V system designs. The integrated A/D converter eliminates the need for external ADC chips in many designs, reducing BOM cost and PCB footprint. Architecturally, the PIC16C715 employs a 14-bit instruction word with separate program and data buses (Harvard architecture), enabling most instructions to execute in a single instruction cycle. The 8-level deep hardware stack supports nested subroutine calls without software overhead. This OTP-based device is one-time programmable, meaning program memory cannot be erased electrically - making it suitable for production volumes but less ideal for prototyping compared to flash-based PIC16F series. Typical applications include industrial control systems, appliance controllers, automotive sensor interfaces, consumer electronics, low-cost data acquisition systems, and battery-powered instruments. The integrated A/D makes it particularly suited for any application needing analog signal measurement alongside digital I/O control. When designing with the PIC16C715-20/P, remember that it is OTP memory - firmware is permanently written at production time and cannot be updated in the field. For designs requiring in-field reprogrammability or prototype iteration, Microchip recommends migrating to the flash-based PIC16F716, which offers similar peripherals and pin compatibility while supporting hundreds of erase/write cycles.

PIC16C715-20/SO - 8-Bit 20MHz OTP MCU 3.5KB 18-SOIC | Microchip

The Microchip Technology PIC16C715-20/SO is an 8-bit CMOS OTP (One-Time Programmable) microcontroller from the PIC16C7X mid-range family, operating at up to 20MHz with 200ns instruction execution, packaged in an 18-pin SOIC (0.295", 7.50mm width) with 3.5KB (2K x 14) of program memory and 128 bytes of RAM, and featuring an integrated 4-channel 8-bit Analog-to-Digital converter. Background - what is an OTP microcontroller? An OTP (One-Time Programmable) microcontroller is a non-erasable variant of flash/EPROM-based MCUs that is programmed once at production or in-system and cannot be reprogrammed. OTP parts are commonly used where cost-sensitive, high-volume consumer or industrial applications do not require firmware updates. They sit within the broader category of 8-bit microcontrollers (8-bit MCU -> microcontroller -> embedded processor -> semiconductor), and the PIC16C715 belongs to Microchip's PIC16 mid-range architecture that uses a 14-bit instruction word and 35 single-word instructions. Key features include a 13-bit I/O count, four 8-bit A/D input channels for direct sensor interfacing, low-power CMOS static design with a commercial 0C to +70C operating range, watchdog timer, power-on reset, and a programmable code-protection mechanism. The RISC architecture delivers deterministic interrupt response and predictable cycle counts - essential for real-time control loops. The PIC16C715 architecture combines a Harvard bus with separate program and data paths, allowing the 14-bit instruction fetch and 8-bit data read/write to occur in the same cycle. The 8-bit ADC includes its own sample-and-hold, and the device is upwards compatible with PIC16C5X and PIC12CXXX for code portability. With the '-20' speed grade, the oscillator supports up 20MHz, providing roughly 5 MIPS throughput. Typical applications include appliance control boards, simple sensor interfaces that need on-chip ADC, low-cost consumer products, automotive body modules (legacy), industrial timers and counters, and remote-control transmitters. The integrated ADC removes the need for an external analog front end in cost-sensitive designs. When designing with this device, note that the PIC16C715 is OTP and cannot be firmware-updated in the field - use PIC16F716 or PIC16F716-I/SO for flash-based equivalents. Commercial grade (0C to +70C) limits deployment in extended-temperature environments; consider PIC16C715-20I/SO for industrial -40C to +85C.

The architecture is built on a Harvard-style RISC core with a 14-bit instruction word, two-stage pipeline, and 8-bit data path. The OTP program memory is implemented as EPROM cells, providing non-volatility at lower cost than flash. The 20 MHz clock rate delivers 5 MIPS of throughput, sufficient for sensor sampling, motor control loops, and simple user-interface tasks. Typical applications include automotive body controllers, sensor signal conditioning, simple motor drivers, battery management, and white-goods appliance controls. The automotive temperature grade (-40C to +125C) qualifies the part for under-hood and cabin electronic modules. When designing with this part, ensure the ICSP programming header is accessible during board bring-up, because OTP memory cannot be erased and re-flashed in production.

PIC16C715T-20E/SS - 8-bit 20MHz OTP MCU 3.5KB | Microchip

The Microchip Technology PIC16C715T-20E/SS is a 8-bit CMOS OTP (One-Time Programmable) microcontroller from the PIC16C71X mid-range family, operating at up to 20 MHz with 200 ns instruction execution, packaged in a 20-pin SSOP (Shrink Small Outline Package). It integrates 3.5 KB of program memory (2K x 14) and 128 bytes of RAM with 35 single-word instructions, packaged in tape-and-reel format as indicated by the "T" suffix and supplied in an industrial-grade SSOP outline. A PIC (Peripheral Interface Controller) microcontroller is a compact RISC-based computer-on-a-chip that integrates a CPU core, non-volatile program memory, working RAM, and peripheral blocks such as timers, comparators and analog-to-digital converters. The PIC16C71X family belongs to Microchip's PIC16 mid-range architecture, positioned between the baseline PIC10/12/16 families and the high-performance PIC18/dsPIC lines, and is widely used in cost-sensitive embedded designs that need an integrated ADC. Key features of the PIC16C715 include 4 channels of 8-bit ADC, an integrated 8-bit timer/counter with 8-bit prescaler, a Watchdog Timer with its own on-chip RC oscillator, an 8-level deep hardware stack, and a programmable code protection mechanism. The device operates across 2.5 V to 6.0 V (typical 5 V) with industrial temperature range support, and the "E" suffix designates the extended temperature grade. Architecturally, the PIC16C715 uses a Harvard-style RISC core with separate program and data buses, allowing instruction fetch and operand access to occur in the same cycle. Its OTP EPROM program memory is one-time programmable using a standard EPROM programmer, which historically made this part popular for low-to-medium volume production runs before Flash-based PIC16F equivalents became dominant. Microchip now recommends the pin-compatible PIC16F716 as the modern flash-reprogrammable replacement. Typical applications include motor control front-ends, automotive sensor interfaces, white goods and appliance control, low-cost remote sensors, and battery-powered instrument front panels that benefit from integrated ADC. Its small 20-pin SSOP footprint also suits consumer products where PCB area is at a premium. Designers should note that OTP parts cannot be re-programmed in-circuit; production firmware must therefore be fully validated before programming. The "-20E" suffix indicates 20 MHz maximum clock with extended operating temperature range, while the SSOP package offers a more compact alternative to the PDIP for space-constrained layouts.

PIC16C715T-20I/SS - 8-bit OTP MCU 3.5KB EPROM 20MHz 20-SSOP | Microchip

The Microchip Technology PIC16C715T-20I/SS is an 8-bit CMOS OTP-based PIC16C mid-range microcontroller packaged in a 20-pin SSOP and rated for the industrial temperature range (-40C to +85C). It integrates a 3.5KB (2K x 14) one-time-programmable program memory, 128 bytes of RAM, 13 digital I/O lines, a 4-channel 8-bit analog-to-digital converter (ADC), and a 20 MHz internal oscillator option that delivers 200 ns instruction execution. What is an OTP microcontroller? An OTP (One-Time-Programmable) microcontroller is a class of MCU whose program memory can be written only once after manufacture, using an external programmer. OTP parts are widely used in cost-sensitive, high-volume consumer and industrial products where firmware is finalized at production time and field re-programmability is not required. Within the broader semiconductor hierarchy, OTP MCUs sit under: microcontroller -> embedded processor -> digital IC -> semiconductor. The PIC16C715 belongs to Microchip's PIC16C mid-range family, which combines RISC architecture (35 single-word instructions) with integrated analog peripherals for compact mixed-signal designs. Key features include PIC16C5X/PIC12CXXX upward source-code compatibility, 4-channel 8-bit ADC with selectable reference, low-power CMOS design, on-chip reset and watchdog timer, and a wide 2.5V to 5.5V VDD operating range. The 20-SSOP (209-mil) package is footprint-compatible with other PIC16C71X and PIC16F71X family members, simplifying PCB layout migration. Power-saving SLEEP mode and a programmable code-protection bit round out the peripheral set for cost-driven embedded control. Architecturally, the PIC16C715 uses a Harvard-class RISC core with separate program (14-bit wide OTP) and data (8-bit wide SRAM) buses, allowing simultaneous instruction fetch and operand access. The 200 ns instruction cycle at 20 MHz oscillator provides deterministic 5 MIPS throughput suitable for closed-loop control loops, sensor signal conditioning, and simple user-interface handling in appliance and automotive body-electronics segments. Typical applications include appliance control boards, battery chargers, simple sensor interfaces with on-board ADC conversion, LED/LCD indicator drivers, and low-cost industrial controllers. Designers migrating to flash-based firmware should consider the newer PIC16F716, which Microchip recommends as a functional replacement with in-circuit reprogrammability. Design consideration: the OTP window is write-once, so verify firmware with a windowed or equivalent flash sibling (PIC16F716) before committing to masked production parts. Decouple VDD with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, and route the MCLR/VPP trace away from switching nodes to avoid spurious resets. This page synthesizes Microchip PIC16C715 family documentation, current distributor pricing as of 2026-09-18, drop-in same-family replacements, and practical design notes that go beyond what is in the standalone datasheet to assist engineers in sourcing, replacement, and layout decisions.

PIC16C716-04E/P

PIC16C716-04E/P - 8-bit OTP MCU, 4MHz, 3.5KB | Microchip

The Microchip Technology PIC16C716-04E/P is a high-performance 8-bit CMOS RISC microcontroller with an integrated 8-bit A/D converter and Capture/Compare/PWM (CCP) peripheral, supplied in an 18-pin PDIP (Plastic DIP-18, 0.300 inch) through-hole package. It operates at up to 4 MHz clock input and delivers a 200 ns instruction cycle, ships with 3.5 KB of OTP program memory (2K x 14) and 128 bytes of data RAM, and offers 13 general-purpose I/O pins. The '04' speed grade (4 MHz) and 'E' (extended) temperature range make it a long-lifecycle component well-suited to industrial and embedded control designs. What is an OTP PIC microcontroller? An OTP (One-Time Programmable) PIC16C-series MCU is a class of 8-bit Reduced Instruction Set Computer (RISC) microcontroller built on EPROM-based program memory, meaning the firmware is burned in by the user exactly once and cannot be erased. The PIC16C architecture belongs to the mid-range PICmicro family, which sits between the baseline PIC10/12 and the enhanced PIC17/18 families in Microchip's 8-bit portfolio. OTPs are preferred over windowed (UV-erasable) parts when code has matured and a low-cost production device is required, and they are commonly used where field re-programmability is unnecessary. Key features include 4 channels of 8-bit A/D conversion, a Timer0 with 8-bit prescaler, a 16-bit Timer1, an 8-bit Timer2, an enhanced CCP module for PWM and capture/compare, a watchdog timer with on-chip RC oscillator, brown-out reset (BOR) circuitry, an in-circuit serial programming (ICSP) interface, and selectable oscillator modes including RC, LP, XT, HS and internal options on related family members. Only 35 single-word instructions keep the learning curve shallow, and most instructions execute in one instruction cycle, leaving more MIPS headroom for the application. Architecturally, the PIC16C716 uses a Harvard-class RISC core with separate program and data buses and a 14-bit-wide instruction word, allowing single-cycle execution for almost all op-codes. Program branches cost two cycles. With a 4 MHz oscillator the core executes 5 MIPS, an attractive figure for the era and still adequate for many slow-control loops today. Typical applications include automotive body and interior electronics, white-goods and appliance control boards, simple sensor interfaces with on-chip ADC, low-cost industrial timers and counters, and consumer products requiring a stable, non-reprogrammable controller. The integrated ADC eliminates an external converter in many designs, while the CCP peripheral reduces external timer/PWM hardware. When designing with this part, choose the PIC16F equivalent if in-circuit reprogrammability is needed in production; reserve the PIC16C OTP for cost-sensitive, code-frozen production runs. Place a 0.1 uF decoupling capacitor close to VDD and follow Microchip's recommended oscillator layout for the chosen resonator or crystal. This page synthesizes verified distributor pricing, drop-in same-package alternatives, and practical design notes not found in the manufacturer datasheet, providing a single engineering reference for the PIC16C716-04E/P.
