PIC16C711T-04/SS - 4MHz 8-bit OTP MCU 1.75KB | Microchip

The Microchip Technology PIC16C711T-04/SS is a high-performance CMOS OTP-based 8-bit microcontroller from the PIC16CXX mid-range family, packaged in a 20-pin SSOP (Shrink Small Outline Package) and supplied in tape-and-reel format. It integrates 1.75KB (1K x 14) of one-time-programmable program memory, 68 bytes of data RAM, 13 digital I/O lines, and a 4-channel 8-bit analog-to-digital converter (ADC). The device executes instructions in a 200 ns cycle at a 4 MHz oscillator input, drawing very low operating current for battery-friendly designs. A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory, working RAM, and a configurable set of peripherals such as ADC, timers, and GPIO. The PIC16C711 belongs to the broader mid-range PIC taxonomy (PIC16C -> 8-bit PIC -> PIC architecture -> microcontroller -> semiconductor IC) and was designed as an upward-compatible evolution of the earlier PIC16C5X baseline family. The integrated 8-bit ADC made it especially attractive for sensor-interface designs where a separate ADC IC would otherwise be required. Key features include a 4 MHz maximum clock frequency with 200 ns instruction cycle, 1.75 KB (1024 x 14) of OTP program memory, 68 bytes of data RAM, 13 bidirectional I/O pins, four multiplexed 8-bit ADC channels, and a wide 4 V to 6 V supply range. Peripherals include a single 8-bit timer/counter with prescaler, a watchdog timer with dedicated on-chip RC oscillator, and a power-on reset (POR) circuit. The 20-pin SSOP footprint supports compact designs in industrial temperature grade. Architecturally, the PIC16C711 uses a RISC-style Harvard architecture with separate program (14-bit) and data (8-bit) buses, allowing simultaneous fetch and access. The 35 single-word instruction set is fully upward-compatible with the PIC16C5X baseline family, easing migration of legacy code. The integrated 8-bit ADC employs a successive-approximation register (SAR) topology with four multiplexed input channels selected through the ADCON0 register. Typical applications include industrial sensor signal acquisition, white-goods and appliance control, low-cost battery-powered instrumentation, automotive body electronics (in non-safety systems), and embedded control subsystems requiring on-chip ADC. The OTP memory suits a target final product profile rather than field-upgradeable firmware, making the part best suited for high-volume production where unit cost matters more than in-circuit reprogrammability. When designing with this device, note that Microchip explicitly recommends the flash-based PIC16F716 as a newer alternative for new designs. The OTP memory cannot be erased or rewritten, so firmware must be fully validated before programming. Decoupling capacitors (100 nF ceramic plus a bulk electrolytic) must be placed close to the VDD/VSS pins to ensure clean ADC readings.

PIC16C711T-04E/SS

PIC16C711T-04E/SS - 4MHz 8-Bit OTP MCU 1.75KB | Microchip SSOP-20

The Microchip Technology PIC16C711T-04E/SS is a 4 MHz 8-bit CMOS OTP-based PIC microcontroller with 1.75KB (1K x 14) of program memory, 68 bytes of RAM, and 13 general-purpose I/O pins, housed in a 20-pin SSOP (0.209", 5.30mm width) surface-mount package. An 8-bit microcontroller (MCU) is a small, low-power computer-on-a-chip that integrates a CPU core, program memory (ROM/Flash/OTP), data RAM, and peripherals onto a single silicon die. It executes instructions fetched from non-volatile program memory and operates on data stored in volatile RAM. Microcontrollers sit in the device hierarchy deep-IC > microcontroller > embedded controller > semiconductor. The "PIC" family from Microchip uses a Harvard architecture and a reduced instruction set (RISC) optimized for deterministic, single-cycle execution. OTP (One-Time Programmable) versions like the PIC16C711 are programmed once with a device programmer and cannot be electrically erased, distinguishing them from Flash-based siblings such as the PIC16F716, which Microchip explicitly recommends as the modern equivalent. Key features include 4 channels of 8-bit Analog-to-Digital conversion (ADC), a Brown-out Reset (BOR), Power-on Reset (POR), and a Watchdog Timer (WDT). The core runs each instruction in 200 ns at 4 MHz, executes only 35 single-word instructions, and offers 13 I/O pins plus an 8-bit timer. Operating voltage is 4.0V to 6.0V and the part operates over the standard PIC16C commercial/extended temperature grade. The PIC16C711 architecture places the ADC and core analog reference on-chip, eliminating external analog conditioning for low-channel-count embedded designs. Its 14-bit instruction word (vs. 12-bit on PIC16C5X baseline parts) gives a flatter mid-range instruction set, and the chip is source-code compatible upward through the PIC16CXX mid-range family. The "/SS" suffix denotes the SSOP-20 package, the "T" denotes Tape & Reel, "04" denotes 4 MHz maximum clock, and "E" denotes the Extended operating temperature range. Typical applications include appliance control, sensor signal conditioning with on-chip ADC, low-cost remote keyless entry transmitters, smoke-detector front-ends, battery chargers, and small motor driver logic boards where the ADC is the primary analog asset and BOM cost is critical. Designers should bias the MCLR pin properly and follow Microchip's recommended decoupling (100 nF + 10 uF bulk) when laying out the PCB. Use ICD or a production programmer compatible with OTP windows to program the device.

It integrates 1.75 KB (1K x 14) of OTP program memory, 68 bytes of RAM, 13 digital I/O lines, and a 4-channel 8-bit analog-to-digital converter on-chip, providing a complete mixed-signal control solution in a single 18-SOIC. What is an 8-bit OTP microcontroller? An 8-bit OTP (One-Time Programmable) microcontroller is a small, low-cost CMOS processor that fetches 8-bit-wide data from non-volatile, one-time-writable program memory and executes a fixed RISC instruction set. The OTP memory is programmed once with the application code and cannot be erased, which makes these MCUs inexpensive and secure in high-volume, cost-sensitive embedded designs where firmware revisions are not required. The PIC16C711 belongs to the mid-range PIC16CXX family, which sits in the broader hierarchy: 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. Key features include 35 single-word instructions, an 8-bit timer/counter, a watchdog timer with on-chip RC oscillator, in-circuit serial programming via two pins, an internal 4 MHz RC oscillator option, and wide operating voltage from 2.5V to 6.0V. The integrated 8-bit ADC features 4 input channels with analog input multiplexer, providing a 10-bit equivalent accuracy using the supply as reference. Technically, the PIC16C711 uses a RISC-based Harvard architecture with separate program and data buses, enabling simultaneous instruction fetch and data access. Its 4 MHz oscillator with 4:1 divider yields 1 MIPS throughput, sufficient for sensor sampling, keypad scanning, motor commutation, and simple control loops. The industrial temperature grade (-40C to +85C) suits industrial automation and outdoor equipment. Typical applications include appliance control, battery chargers, sensor signal conditioning, LED drivers, and consumer white goods. The integrated ADC makes it well suited for low-cost data acquisition in industrial sensors, while the 13 I/O pins support keypad matrix, LCD segment driving, or relay control. When designing with this part, consider that OTP memory cannot be re-programmed, so choose a flash-based PIC16F equivalent (such as the manufacturer-recommended PIC16F716) for prototypes or any design where firmware revisions are expected. Decoupling capacitors (0.1 uF Vdd-to-Vss) and a properly placed reset pull-up are essential for reliable operation.

Key features include the 4 MHz maximum clock rate, 1.75 KB OTP program memory (1K x 14 words), 68 bytes of data RAM, four 8-bit I/O ports (PORTA 5 bits, PORTB 8 bits), and a 4-channel 8-bit ADC with on-chip sample-and-hold. The device supports in-circuit serial programming, low-power SLEEP mode, and a programmable watchdog timer. The RISC-style PIC16 architecture uses only 35 single-word instructions, simplifying code generation in C or assembly. Built on a low-power CMOS process, the PIC16C711 implements the PIC16 mid-range core with a 14-bit instruction word and an 8-bit data path. The integrated 8-bit ADC samples analog inputs on RA0-RA3, allowing direct connection of resistive sensors, thermistors, or potentiometers without external signal conditioning. The internal RC oscillator option and power-on reset reduce external component count. Typical applications include white-goods and appliance control (washing machines, dishwashers, microwave ovens), battery chargers, automotive body electronics (non-safety subsystems), sensor signal conditioning nodes, and small consumer devices (remote controls, thermostats, toy subsystems). The 4 MHz industrial-grade part is well-matched to mains-frequency signal processing and slow control loops. When designing with this part, ensure the OTP window is left on or off according to the in-circuit-programming method selected, place a 0.1 µF decoupling capacitor within 5 mm of VDD, and reserve the RA4 pin as an open-drain output if used for T0CKI. The Microchip PIC16F716 is the recommended newer pin-compatible alternative for new designs requiring flash memory, while PIC16C711T-04I/SS remains preferred for high-volume cost-down production.

The Microchip Technology PIC16C711T-20E/SO is an 8-bit RISC microcontroller from the PIC16C family with 20MHz maximum clock speed, 1.75KB (1K x 14) One-Time Programmable (OTP) program memory and 68 bytes of RAM, housed in an 18-pin SOIC package with automotive-grade (-40C to +125C) operating temperature. What is an 8-bit OTP microcontroller? It is a single-chip computer built around an 8-bit data path, integrating CPU, ROM/EPROM/Flash program memory, RAM, and peripherals into one package. OTP variants are programmed once after manufacture using a device programmer - cheaper than Flash but not reprogrammable. The PIC16C71X family adds an on-chip 8-bit Analog-to-Digital Converter (ADC), positioning this MCU between bare 8-bit controllers and higher-pin-count PIC16F parts in the Microchip PIC taxonomy: microcontroller -> 8-bit MCU -> PIC16 mid-range -> PIC16C71X. Key features include 13 digital I/O pins, an integrated 8-bit ADC with 4 input channels, a 35-instruction RISC instruction set with 200ns instruction execution time, and a wide operating voltage range that supports both 5V and lower-voltage designs. Per the Microchip product page, Microchip recommends the newer PIC16F716 as a direct replacement for new designs; this EOL-style legacy part is maintained for existing automotive and industrial designs. The PIC16C71X uses a Harvard-architecture CPU with separate program and data buses, allowing simultaneous instruction fetch and data access. The CMOS process delivers low power consumption, and the integrated ADC eliminates the need for an external converter in simple sensor-reading applications. Typical applications include automotive sensor interfaces, industrial control logic, appliance controllers, and legacy embedded systems. The integrated ADC and 13 I/O make it well suited to simple mixed-signal designs where a higher-pin-count MCU would be wasteful. When migrating from this part, consider PIC16F716 (Flash-based, same family) for new designs. The OTP memory makes field updates impossible, so choose PIC16F716 if your firmware may need in-system reprogramming. Source from authorized distributors only - counterfeit OTP PICs are common.

PIC16C711T-20E/SS - 8-Bit 20MHz OTP MCU w/ ADC | Microchip

The Microchip Technology PIC16C711T-20E/SS is an 8-bit CMOS OTP-based microcontroller in the PIC16CXX mid-range family, integrating 1.75KB (1K x 14) of One-Time-Programmable program memory, 68 bytes of RAM, and a 4-channel 8-bit analog-to-digital converter in a 20-pin SSOP package. The device executes instructions in a 200 ns single-cycle period at 20 MHz maximum clock, providing 5 MIPS throughput while operating from a 4.0 V to 6.0 V supply, and is offered in the industrial -40C to +125C temperature grade. An 8-bit microcontroller (MCU) is a programmable single-chip computer built around an 8-bit data path, on-chip program memory, working RAM, and a set of peripheral blocks such as timers, communication interfaces, and analog converters. The PIC16C711 belongs to the mid-range PIC16CXXX family, which sits architecturally between Microchip's baseline PIC10/12/16/17 and enhanced PIC18 families. These microcontrollers are categorized as: microcontroller -> embedded controller -> semiconductor -> integrated circuit. The PIC16CXXX family hierarchy is: PIC16CXXX -> PIC16C711 -> PIC16C711T-20E/SS. Key features of the PIC16C711T-20E/SS include 13 general-purpose digital I/O pins, brown-out detect (BOD) and power-on reset (POR) for safe supply-ramp operation, a watchdog timer (WDT) with its own on-chip RC oscillator, and a 4-channel 8-bit ADC for mixed-signal sensing. The core uses a RISC Harvard architecture with only 35 single-word instructions, simplifying firmware development and code density. The OTP program memory is programmed once and cannot be electrically erased, making this part well-suited for mature, high-volume production where firmware is stable. In system design, the PIC16C711T-20E/SS is a fully static CMOS device, allowing the clock to be stopped without losing register state - useful for low-power sleep-mode applications. The internal architecture separates program and data buses (Harvard), enabling simultaneous instruction fetch and operand access. Peripherals are memory-mapped, accessed through dedicated Special Function Registers (SFRs), and interrupts are prioritized with a single vector plus context save/restore hardware. This engineering foundation has made the PIC16C711 one of the most widely cloned 8-bit MCU footprints in industry. Typical applications include industrial automation controllers, sensor signal conditioning with on-chip ADC, appliance control boards, automotive body and HVAC modules, and consumer electronics requiring deterministic 8-bit control. The 20-pin SSOP footprint makes it drop-in compatible with the broader PIC16C71X family, easing PCB layout reuse across product variants. A modern flash-based equivalent, the PIC16F716, is recommended by Microchip for new designs while the PIC16C711T-20E/SS continues to be supported for existing production. When designing with this device, note that the OTP memory cannot be re-programmed, so firmware must be fully validated before programming. The ADC reference is software-selectable; using VDD as Vref simplifies BOM but reduces absolute accuracy. The 20 MHz clock and 35-instruction RISC core deliver deterministic execution time, which is essential for closed-loop control and timing-sensitive sensor interfaces.

PIC16C711T-20I/SO

PIC16C711T-20I/SO - 8-Bit 20MHz OTP MCU 1.75KB | Microchip

The Microchip Technology PIC16C711T-20I/SO is an 8-bit CMOS OTP-based microcontroller from the PIC16C711 family, featuring 1.75 KB (1K x 14) of program memory, 68 bytes of RAM, and 13 I/O pins, all integrated in a surface-mount 18-SOIC package. It executes instructions in 200 ns (20 MHz clock), supports 35 single-word instructions, and operates from 4 V to 6 V supply voltage across an industrial temperature range of -40 °C to +85 °C. What is an OTP microcontroller? An OTP (One-Time Programmable) microcontroller is a class of MCU whose on-chip program memory can be written exactly once by the end user, after which the bit pattern becomes permanent and non-erasable. OTP MCUs sit between full EEPROM/Flash MCUs (reprogrammable) and mask-ROM MCUs (factory-programmed only). They are commonly used in cost-sensitive, low-to-medium volume production where the design is stable but the volumes do not justify mask-ROM tooling; OTP sits in the broader hierarchy: microcontroller -> embedded MCU -> semiconductor IC. The PIC16C711T integrates an 8-bit ADC, watchdog timer, and Brown-out Reset, which makes it attractive for simple sensor-interface products. Key features of this part include four 8-bit A/D converter channels, an internal RC oscillator option, power-saving SLEEP mode, and an in-circuit serial programming (ICSP) interface via two pins. The 8-bit successive-approximation ADC supports analog input multiplexing with acquisition timing controlled by the on-chip hardware, enabling direct connection to sensors such as thermistors, potentiometers, and battery voltage dividers. Architecturally, the PIC16C711T uses Microchip's Harvard RISC core with separate program and data buses. Program memory is 14-bit wide OTP EPROM, while data memory is 8-bit wide static RAM. The 13 I/O pins are arranged on PORT A (5 pins, shared with analog inputs) and PORT B (8 pins), with programmable weak pull-ups on PORT B and interrupt-on-change capability on PORT B <4:7>. Typical applications for PIC16C711T-20I/SO include low-cost sensor signal conditioning, battery chargers, small appliance controllers, and educational/training boards. It is also widely used as a direct drop-in for legacy designs where a flash MCU is unnecessary. Designers building new products today are advised to consider the PIC16F716 (Flash-based replacement recommended by Microchip). A key design tip: the analog reference voltage (Vref) must be decoupled with a 0.1 µF ceramic capacitor placed within 5 mm of the pin, and the analog supply (AVdd) should be tied to Vdd through a ferrite bead to avoid ADC noise coupling from digital switching. Always leave one pin as a hardware reset (MCLR) when possible to prevent code lockup.

PIC16C711T-20I/SS - 8-bit OTP MCU, 1.75KB, 13 I/O, 20MHz SSOP-20 | Industrial

The Microchip PIC16C711T-20I/SS is an 8-bit, OTP-based CMOS microcontroller in the PIC16CXX mid-range family, offering 1.75KB of program memory (organized as 1K x 14), 68 bytes of RAM, 13 general-purpose digital I/O pins, and an integrated 8-bit A/D converter with four input channels. The device operates from a 4V to 6V input rail (typical 5V), executes instructions in 200 ns at 20 MHz, and is housed in a 20-pin SSOP (209 mil) surface-mount package supplied on Tape & Reel. What is an OTP microcontroller? An OTP (One-Time Programmable) microcontroller is a class of MCU whose program memory is implemented as factory-or-user-programmable EPROM cells that can be written exactly once and cannot be electrically erased. OTP MCUs belong to the legacy MCU hierarchy MCU -> microcontroller -> embedded controller -> semiconductor, and they sit between mask-ROM MCUs (cheapest at high volume) and Flash MCUs (most flexible). The PIC16C711 series was designed for cost-sensitive, low-to-medium volume production where the simplicity of a 35-instruction RISC core outweighs the lack of in-circuit reprogrammability. Key features of the PIC16C711T-20I/SS are its 200 ns instruction cycle, 4-channel 8-bit ADC with selectable reference, brown-out reset circuitry, a 15-bit programmable prescaler, one 8-bit and one 16-bit timer/counter, and a wide 4.0V to 6.0V operating range. The PIC RISC architecture delivers deterministic interrupt latency and Harvard bus structure for simultaneous instruction fetch and data access, while the industrial temperature grade (-40C to +85C) supports harsh-environment deployment. Architecturally, the PIC16C711T-20I/SS uses a 14-bit instruction word with an 8-bit data path, a hardware multiplier-free ALU, and a two-stack-deep return address register. The integrated ADC samples through successive approximation with an acquisition time that is user-programmable, and the analog reference can be sourced from the supply rail or an external pin for ratiometric measurements. Typical applications include industrial sensor signal conditioning, motor and valve control loops, consumer appliance controllers, automotive body electronics (where the automotive -I suffix grade is not used; the part is industrial-grade only), and low-cost white-goods user interfaces. Designers favor the PIC16C711 family for its predictable interrupt behaviour, breadboard-friendly SSOP-20 footprint, and Microchip's free MPLAB development toolchain. A newer Flash-based drop-in replacement, the PIC16F716, is recommended for new designs per the manufacturer's product page; the PIC16C711T-20I/SS remains stocked for legacy and long-life programs. When designing with this part, observe the 4V minimum Vdd for guaranteed ADC accuracy, place a 100 nF ceramic bypass capacitor within 5 mm of Vdd/Vss, and reserve pin 1 (MCLR/Vpp) for the high-voltage programming signal - tying it directly to Vdd disables in-circuit programming. OTP parts cannot be re-programmed, so prototype and verify on a Flash equivalent before committing to OTP volume orders. As of 2026-09-18 the LCSC distributor lists it from $1.46 in stock.

PIC16C712-04/SO - 8-bit 4MHz OTP MCU 1.75KB | Microchip

The Microchip Technology PIC16C712-04/SO is an 8-bit CMOS OTP-based microcontroller built on the PIC16C architecture, delivering 4 MHz (200 ns instruction cycle) performance in an 18-pin SOIC package. According to the Microchip product page, the device integrates 1.75 KB of OTP program memory (1K x 14 words), 128 bytes of RAM, and 13 general-purpose I/O pins, plus a 4-channel 8-bit Analog-to-Digital Converter (ADC), two timers, and a Capture/Compare/PWM (CCP) module for advanced control tasks. The -04 speed suffix denotes a 4 MHz oscillator maximum at the commercial operating range, while the /SO suffix indicates the 7.50 mm-width 18-SOIC gull-wing surface-mount package supplied in tube packaging. The PIC16C712 is upward code-compatible with the PIC16C5X and PIC12CXXX families, retaining the well-known 35-instruction RISC instruction set that simplifies migration across PIC mid-range designs. What is a PIC16C OTP microcontroller? An OTP (One-Time-Programmable) microcontroller is a microcontroller whose program memory can be written exactly once after manufacture, using a device programmer. OTP parts sit between mask-ROM devices (cheapest at high volume but fixed at the fab) and Flash-based MCUs (re-programmable many times). They are typically chosen for cost-sensitive, high-volume, mature products where firmware is stable and re-programmability is not required. OTP MCUs share the same instruction set, peripherals, and development tools (MPLAB XC8, ICD programmers) as their Flash siblings, enabling engineers to prototype on Flash parts and ship on OTP parts. Key features of the PIC16C712 include: 4 MHz maximum operating frequency (200 ns instruction cycle), 1.75 KB OTP program memory, 128 bytes of data RAM, 13 digital I/O pins with individual direction control, 4-channel 8-bit ADC, two 8-bit timers (Timer0 and Timer2) plus one 16-bit timer (Timer1), one Capture/Compare/PWM module, a watchdog timer with its own on-chip RC oscillator, and an operating voltage range of 2.5 V to 5.5 V (industrial variants). The 8-bit RISC Harvard architecture executes one instruction per cycle, giving deterministic timing suitable for real-time control. Programmable code protection, power-on reset, brown-out detection (on selected variants), and an in-circuit serial programming (ICSP) interface simplify end-of-line firmware updates during production. Typical applications include white-goods and appliance control, automotive body and sensor modules, industrial sensor interfaces, low-end motor control loops with CCP-driven PWM, simple closed-loop thermostats, and consumer electronic subsystems. The CCP module plus 4-channel ADC makes the PIC16C712 well suited to mixed analog/digital control tasks in cost-sensitive products. When laying out the board, place a 100 nF decoupling capacitor within 5 mm of VDD, route the 4 MHz crystal traces as short as possible with grounded guard rings, and reserve the MCLR pin for an in-system programming header. Note that OTP memory cannot be erased, so production firmware must be fully verified before programming.

The PIC16C712 is pin-compatible with the PIC16C71x family and shares the same RISC-based PIC16 architecture as older PIC16Cxx devices. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, memory (program + data), peripherals (timers, ADC, communication), and I/O pins on one IC. The PIC16C712 belongs to the PIC16 mid-range family — a category of 8-bit RISC microcontrollers from Microchip Technology widely used in embedded control. Within the broader taxonomy it sits as: microcontroller -> 8-bit MCU -> PIC16 mid-range -> PIC16C71x sub-family. RISC architecture, OTP memory and integrated ADC make this category the workhorse for cost-sensitive, low-volume embedded designs. Key features of the PIC16C712 include: 13 I/O pins (one input-only), four interrupt sources, two 8-bit timers (Timer0, Timer2) plus one 16-bit timer (Timer1) with capture, a 4-channel 8-bit ADC, and a Capture/Compare/PWM module. The Harvard memory architecture separates program (1.75 KB EPROM) and data (128 B SRAM) buses to allow simultaneous instruction fetch and operand access, improving throughput vs. von-Neumann CISC 8-bit MCUs of the same vintage. The PIC16C712 uses a 14-bit wide instruction word with 35 single-cycle opcodes, delivering 4 MIPS at 4 MHz. Internal RC oscillator and external crystal/RC modes are supported. The 8-bit successive-approximation ADC shares pins with digital I/O and has its own reference inputs (VREF+/VRREF-). Brown-out Reset, Power-on Reset, Watchdog Timer with on-chip RC oscillator, and code protection protect firmware in noisy industrial environments. Typical applications include industrial appliance control, automotive subsystems (HVAC, lighting, instrument clusters), consumer products, and analog-signal-conditioning front-ends where the integrated ADC eliminates an external converter. Designers choose the PIC16C712 for cost-sensitive production runs where OTP programming is acceptable. When designing with this device, account for OTP memory — firmware cannot be updated in the field. Engineers developing prototypes should use the PIC16F712 flash variant for iteration, then migrate the validated firmware to the PIC16C712 for low-cost production. The 4 MHz speed grade supports instruction execution up to 1 us per instruction. This page synthesizes distributor pricing, cross-reference data, and design notes that are not aggregated in any single manufacturer or distributor source, giving engineers a single reference for evaluating drop-in substitutes and lifecycle risk.

The PIC16C7xx family specifically targets applications that require on-chip analog conversion and PWM generation, eliminating the need for external ADC or timer ICs in cost-sensitive industrial, automotive, appliance, and consumer designs. Key differentiating specifications include the 35-instruction RISC instruction set (all single-cycle except program branches), the integrated 8-bit ADC with 4 input channels, the CCP module supporting PWM generation for motor and lighting control, and the wide operating voltage range of 2.5V to 5.5V with automotive temperature grade support (-40C to +125C). The device also integrates a Watchdog Timer with its own on-chip RC oscillator for reliable operation in noisy environments. The PIC16C712-04E/P is fabricated in CMOS technology, offering low power consumption with standby currents below 1 microamp. Its Harvard architecture separates program and data buses, enabling simultaneous instruction fetch and data access, which is why a 4 MHz oscillator can execute instructions in 200 ns. The device supports in-circuit serial programming (ICSP) via two pins, enabling firmware updates after PCB assembly. Typical applications include automotive sensor interfacing, industrial process control, appliance motor control (washing machines, HVAC fans), consumer white goods, and low-cost data acquisition systems. The 'E' suffix denotes the extended automotive temperature grade of -40C to +125C, while the '04' speed grade indicates 4 MHz maximum operation, and '/P' designates the PDIP package. When designing with this device, ensure that the MCLR pin is properly pulled high through a resistor and that the decoupling capacitor on VDD is placed within 0.25 inches of the supply pin. The OTP memory can be programmed only once, so consider using the PIC16F712 (Flash-based equivalent) for prototypes or production runs that require firmware updates.

What is an 8-bit OTP/EPROM microcontroller? It is a single-chip computer integrating a CPU, non-volatile program memory (one-time-programmable or UV-erasable), RAM, and peripherals such as timers and ADCs. Within the power management and embedded hierarchy, microcontrollers sit at the same tier as DSPs and FPGAs, but are optimized for deterministic control tasks at low cost and low power, and they sit below ASICs in design complexity. PIC16C-series parts belong to Microchip's mid-range 14-bit instruction core family, sitting above the baseline PIC12C and PIC16C5X families and below the PIC17C/PIC18C extended families. Key differentiating features include four channels of 8-bit A/D conversion, two 8-bit timers (Timer0 and Timer2) plus one 16-bit timer (Timer1), a capture/compare/PWM (CCP) module, and a watchdog timer.

It integrates 1.75 KB (1K x 14) of One-Time Programmable program memory, 128 bytes of RAM, 13 general-purpose digital I/O pins, and a 4-channel 8-bit Analog-to-Digital converter. What is a PIC 16C microcontroller? PIC 16C refers to Microchip's mid-range 8-bit OTP (One-Time Programmable) microcontroller family using a RISC Harvard architecture. They execute one instruction per cycle (200 ns at 20 MHz) from a fixed 35-instruction set, sit in the hierarchy PIC microcontroller -> 8-bit MCU -> embedded controller -> semiconductor, and historically served low-cost, high-volume consumer and industrial designs before Flash-based PIC16F parts replaced them in new designs. Key features of the PIC16C712T-04E/SO include Brown-out Detect and Power-on Reset for safe startup, a Watchdog Timer for runaway code recovery, a Capture/Compare/PWM (CCP) peripheral, two 8-bit timers plus one 16-bit timer, and a 4-channel 8-bit ADC. The "04" speed grade denotes 4 MHz operation, while the "E" suffix indicates the Extended industrial temperature range (-40C to +125C). The "T" denotes Tape & Reel packaging for high-volume pick-and-place assembly. Architecturally, the device uses a 14-bit wide instruction word with an 8-bit data path, providing 200 ns instruction cycle at 4 MHz (DC to 4 MHz external clock input). The OTP program memory is one-time programmable, requiring a device programmer such as the PICSTART Plus or MPLAB PM3 - field firmware updates are not possible, which is the primary trade-off versus Flash-based PIC16F successors. Typical applications include appliance control, sensor signal conditioning, simple motor drive (via PWM), automotive body electronics, lighting controllers, and battery-powered industrial sensor nodes where the extended temperature grade and 5V tolerance are advantageous. It is also widely used in legacy equipment repair and industrial retrofit designs where exact pin-compatible replacements are required. When designing with this part, note that OTP memory cannot be reprogrammed, so code must be fully verified before commitment. For new designs, the Flash-based PIC16F716-I/SO is generally preferred for in-system reprogrammability, but the PIC16C712T-04E/SO remains valuable for cost-sensitive, high-volume, code-stable applications.

PIC16C712T-04I/SO

PIC16C712T-04I/SO - 8-Bit 4MHz 1.75KB OTP MCU 18-SOIC | Microchip

The Microchip Technology PIC16C712T-04I/SO is an 8-bit CMOS RISC microcontroller built around the PIC16 architecture, operating at 4 MHz with 1.75 KB (1K x 14) of One-Time Programmable (OTP) program memory and 128 bytes of RAM, housed in a surface-mount 18-pin SOIC (SO) package supplied on tape and reel. The part is a member of the legacy PIC16C71x family and offers 4 channels of 8-bit Analog-to-Digital conversion, a Capture/Compare/PWM (CCP) module, and two additional 8-bit timers beyond the baseline Timer0. A microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, working RAM, and peripheral interfaces onto one silicon die. In the broader semiconductor hierarchy, the PIC16C712 sits within microcontrollers -> embedded processors -> digital ICs -> semiconductors. The "16C" prefix denotes CMOS OTP technology, where the program memory is written once at production time and is non-erasable, making the device well suited to mature, cost-sensitive, high-volume consumer and industrial products where firmware is stable. Key features include 35 single-word RISC instructions, all single-cycle except two-cycle branches, a 200 ns instruction cycle at 20 MHz maximum clock, an 8-level deep hardware stack, and 13 bidirectional I/O pins with individual direction control. The 4-channel 8-bit A/D converter simplifies sensor-interface designs, while the CCP module enables simple PWM motor and lighting control without external timing circuitry. The industrial (-40C to +85C) temperature range is encoded in the "I" suffix, and the "04" speed grade marks the 4 MHz operating point. Typical applications include appliance control modules, simple sensor interfaces with on-chip ADC, low-cost PWM fan or LED drivers, and replacement of legacy PIC16C5X designs requiring A/D capability. The 18-SOIC package is the most common PCB-friendly footprint in the family and matches the PIC16C711 / PIC16C710 pinout, simplifying layout migration. When designing with this device, note that OTP memory cannot be re-programmed in the field, so firmware must be fully validated before production programming. Consider the flash-based PIC16F716 or PIC16F707 as in-system reprogrammable alternatives for new designs. Always de-couple VDD with a 100 nF ceramic capacitor placed within 5 mm of the pin.

PIC16C712T-04I/SS

PIC16C712T-04I/SS - 4MHz 8-Bit OTP MCU, 1.75KB | Microchip

The Microchip Technology PIC16C712T-04I/SS is an 8-bit CMOS OTP (One-Time Programmable) microcontroller from the PIC16C family, operating at 4 MHz with a 200 ns instruction cycle and packaged in a 20-pin SSOP (SS) package with industrial-grade temperature rating. What is a PIC microcontroller? A PIC microcontroller is a family of Harvard-architecture 8/16/32-bit microcontrollers originally developed by Microchip Technology, featuring RISC instruction sets, integrated peripherals (ADC, timers, PWM, communication), and on-chip non-volatile memory. The PIC16C sub-family uses One-Time Programmable EPROM for program storage, which is well-suited to high-volume production where firmware is final and code protection is required. The PIC16C712T-04I/SS sits within this OTP-based 8-bit MCU hierarchy as: 8-bit microcontroller -> RISC MCU -> PIC16C OTP family -> PIC16C7xx series with ADC and PWM. Key features include 1.75 KB of program memory organized as 1K x 14 bits, 128 bytes of data RAM, 13 I/O pins, four 8-bit analog-to-digital converter (ADC) channels, a Capture/Compare/PWM (CCP) module, and integrated peripherals such as Brown-out Detect/Reset, Power-on Reset, and a Watchdog Timer. The 35 single-word RISC instruction set and DC to 4 MHz oscillator range simplify firmware development, while the 20-pin SSOP form factor supports compact surface-mount designs. The PIC16C712 uses a modified Harvard architecture with separate program and data buses, allowing instruction fetch and operand read to occur in the same cycle. The 14-bit wide instruction word provides compact code density, while the 8-bit data path keeps peripheral control straightforward. The integrated 8-bit ADC offers up to four channels with configurable reference voltages, supporting sensor and analog signal conditioning tasks. Typical applications include industrial control subsystems, sensor signal acquisition modules, low-cost consumer appliance controllers, and embedded control boards requiring on-chip ADC plus PWM motor or lighting control. The wide 2.5V to 5.5V supply range and 13 I/O pins provide ample headroom for switches, relays, sensors, and communication interfaces. The OTP memory architecture is intended for production volumes where firmware is fixed and code security is desired. When designing with the PIC16C712T-04I/SS, verify whether OTP or Flash-based memory is appropriate: OTP prevents field firmware updates, so production-grade firmware validation must be complete before programming. For prototype and pre-production work, designers may prefer the Flash-based PIC16F712 equivalent, which supports in-circuit reprogramming. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, including pin-compatible OTP and Flash PIC16 variants and a comparison table for sourcing decisions.
