PIC16C74BT-04I/L - 8-bit OTP MCU, 4MHz, 7KB, 33 I/O | Microchip

The Microchip PIC16C74BT-04I/L is an 8-bit PIC16CXX mid-range microcontroller built on a RISC architecture, offering 4MHz core clock speed, 7KB (4K x 14) of One-Time Programmable (OTP) program memory, 192 bytes of RAM, and 33 general-purpose digital I/O pins, housed in a 44-pin PLCC (J-lead, 16.59x16.59 mm) industrial-temperature package. A PIC microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data RAM, and peripherals into one IC. Within the broader taxonomy, PIC16C74B belongs to the PIC16C family, which sits under the mid-range PIC MCU category, which itself is a subset of 8-bit microcontrollers, which falls under the broader class of embedded controllers and, ultimately, semiconductors. Mid-range PIC MCUs use a 14-bit instruction word and a Harvard architecture with separate program and data buses, which is why this part's program memory is specified as 4K x 14 rather than 4K x 8. Key features of the PIC16C74BT-04I/L include a 20MHz maximum oscillator input, on-chip peripherals such as a multi-channel 8-bit ADC, two 8-bit timers plus one 16-bit timer, a synchronous serial port (SSP) configurable for SPI or I2C, a USART for asynchronous serial communication, a parallel slave port, and a watchdog timer with its own on-chip RC oscillator. The CPU executes 35 instructions, all single-cycle except for program branches, which take two cycles. Industrial temperature grade (-40C to +85C) and 4.0V to 5.5V supply range make it suitable for factory-floor and process-control designs. This device is part of Microchip's PIC16C7X family (PIC16C73B/74B/76/77), all sharing the same peripheral set and pinout family but differing in memory size and package options. The 'B' suffix denotes the enhanced/revision B silicon with improved ADC and peripheral performance compared to the original PIC16C74/A. The 'T' in the MPN indicates tape-and-reel packaging, '-04' specifies the 4MHz speed grade, 'I' is the industrial temperature range, and '/L' denotes the 44-pin PLCC lead finish. Typical applications include industrial control systems, sensor signal conditioning with on-chip ADC, motor control, instrumentation with serial communication links, and embedded control where simple RISC firmware with predictable timing is preferred over more complex 32-bit cores. The wide operating voltage (4.0V-5.5V) and industrial temperature rating allow deployment in factory automation and outdoor equipment. When designing with this device, note that OTP memory cannot be electrically erased - code is committed permanently after programming. Use a windowed CERDIP variant (PIC16C74B-04/JW or PIC16C74B-04/PJW) for development and code revision cycles, then transition to the OTP PLCC for production. Total I/O count (33) excludes pins used for the external crystal/oscillator and the analog Vref input; verify your specific pinout against the datasheet diagram before laying out the PCB. This page synthesizes distributor pricing, verified drop-in alternatives, and practical design notes that go beyond what the manufacturer datasheet alone provides, with all specs cross-referenced against the Microchip PIC16C7X datasheet and current distributor inventory.

It integrates 7KB of One-Time Programmable (OTP) program memory organized as 4K x 14 words, executes instructions at up to 4 MHz, and includes 192 x 8 bytes of data RAM. The 'B' suffix indicates the second-generation PIC16C74 core with the integrated 8-channel, 8-bit analog-to-digital converter. A microcontroller (MCU) is a single-chip computer that contains a CPU, non-volatile program memory, working RAM, and configurable peripherals. Within the broader semiconductor taxonomy, the PIC16C74BT-04I/PQ sits in the 8-bit mid-range MCU category, which itself is a subset of the embedded microcontroller family, sitting below 16-bit and 32-bit MCUs in computational throughput but excelling in deterministic interrupt response, low cost, and ease of programming. OTP memory means the device is programmed once at production; for re-programmable equivalents, the PIC16F74 in the flash-based PIC16F family is the modern counterpart. Key features include 33 digital I/O pins, three serial communication peripherals (I2C/SPI, SPI, and UART/USART), an 8-channel 8-bit ADC, Brown-out Detect and Power-On Reset (POR) for robust supply supervision, and a wide 2.5V to 6.0V operating voltage range. The device supports external oscillator operation, allowing the system designer to choose crystal, resonator, or RC oscillator sources matched to EMI and timing requirements. The PIC16C74BT-04I/PQ is built on Microchip's CMOS, fully-static mid-range architecture, providing low power consumption and instruction execution in a single instruction cycle (excluding branches). With 14-bit instruction width, code density is excellent, allowing rich peripheral interaction in 7KB of memory. The integrated ADC with eight channels makes analog sensor interfacing straightforward without external components. Typical applications include industrial control systems, appliance and HVAC controllers, automotive body electronics, instrumentation front-ends with analog inputs, and embedded sensor hubs requiring UART or SPI host communication. Because the part is OTP, it is best suited to mature, high-volume products where the firmware is finalized and ongoing field updates are not required. Designers should pay attention to the difference between the -04 speed grade (4 MHz) and the -20 speed grade (20 MHz) within the same family; this variant runs at 4 MHz maximum oscillator frequency. The 'T' suffix indicates tape-and-reel packaging, and 'I' indicates the industrial temperature grade.

PIC16C74BT-04I/PT

PIC16C74BT-04I/PT - 8-Bit 4MHz OTP MCU 7KB | TQFP-44 | Microchip

The Microchip Technology PIC16C74BT-04I/PT is an 8-bit RISC microcontroller from the PIC16CXX mid-range family, offering 4 MHz maximum clock speed, 7 KB (4K x 14) of One-Time-Programmable (OTP) program memory, and 192 x 8 bytes of RAM in a 44-pin TQFP (10x10 mm) surface-mount package. The 'I' suffix denotes the industrial temperature grade (-40C to +85C) and '04' specifies the 4 MHz speed variant. What is an 8-bit OTP microcontroller? An 8-bit MCU is a microprocessor unit that processes data 8 bits at a time; OTP (One-Time-Programmable) memory can be written exactly once, making these parts economical for mature, high-volume products where firmware is finalized before production. The PIC16CXX family sits in Microchip's mid-range hierarchy (PIC10/12/16/18 base architecture family -> 8-bit MCU -> microcontroller -> embedded processor) and is widely used in industrial control, automotive subsystems, and consumer appliances. Key features of the PIC16C74BT-04I/PT include 33 digital I/O lines, an external oscillator interface, integrated peripherals suited for embedded control, and CMOS fully-static design that minimizes power consumption. The 35-instruction RISC instruction set simplifies code generation, and the Harvard architecture separates program and data buses for deterministic instruction throughput. Technically, the device operates from a 5 V supply, supports in-circuit serial programming via Microchip's ICSP protocol, and includes brown-out and watchdog features typical of mid-range PIC controllers. The OTP EPROM cell array is well-suited for legacy designs that have moved past prototyping but still demand the reliability and toolchain maturity of the PIC16C architecture. Typical applications include industrial automation controllers, automotive body and chassis subsystems, consumer appliance control boards, and embedded sensor interfaces. The wide operating temperature range and CMOS static design also fit unattended remote data-acquisition nodes. When designing in this part, note that OTP cannot be reprogrammed - any firmware update requires physical replacement. For new designs requiring flash memory, consider the pin-compatible PIC16F74 or PIC16F877A families that share the same 44-pin TQFP footprint. Always confirm timer, ADC, and peripheral parity when migrating firmware from older PIC16C7x designs. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, helping engineers evaluate long-term availability and supply-chain risk for legacy OTP PIC16 designs.

PIC16C74BT-20/PT

PIC16C74BT-20/PT - 8-bit 20MHz OTP MCU 7KB | Microchip TQFP-44

The Microchip Technology PIC16C74BT-20/PT is an 8-bit PIC16C-family CMOS OTP microcontroller running at 20 MHz instruction rate (200 ns per instruction) with 7 KB (4K x 14) of one-time-programmable program memory and 192 bytes of RAM, housed in a 44-pin TQFP (10x10 mm) package. The 'B' suffix designates the mid-range revision with enhanced peripherals versus the original PIC16C74, while the 'T' indicates the tape-and-reel packaging option. An 8-bit OTP microcontroller is a microcontroller based on an 8-bit data-path architecture whose program memory is one-time-programmable - it can be written once by the user (or a programming house) using an EPROM-style cell and cannot be electrically rewritten. OTP parts bridge the gap between masked-ROM volume parts and windowed-EPROM engineering parts, making them well suited to low-volume production, security-sensitive firmware (since the bit pattern is not externally readable after programming), and pre-production builds where final ROM mask conversion is not yet committed. Key features of the PIC16C74BT-20/PT include a Harvard-architecture RISC core with only 35 single-word instructions, eight 8-bit ADC channels (with two additional timers per the family documentation), 2 timers, a USART, MSSP (SPI/I2C), up to 33 digital I/O lines, a 20 MHz clock, and commercial temperature grade (0 C to +70 C). The 44-pin TQFP package provides ample I/O count for human-interface and motor-control front-ends while keeping the PCB footprint under 14 x 14 mm. The PIC16C74B is upwards compatible with the PIC16C5X baseline and PIC12Cxxx devices, so legacy 16C5X assembly code ports with minimal change. The RISC core executes most instructions in a single 200 ns cycle at 20 MHz, delivering up to 5 MIPS throughput - more than adequate for closed-loop control loops running at kHz rates. Brown-out reset, power-on reset, watchdog timer and a wide 2.5-6.0 V VDD range round out the analog/mixed-signal integration. Typical applications include industrial control front-ends, appliance control boards, automotive body modules (verified AEC-Q100 variants exist in the family), security and access-control panels, sensor signal conditioning, and small consumer appliances. The OTP nature suits designs shipping in the thousands to hundreds of thousands where masking the firmware is preferable but flash re-programmability is not required. When designing with this part, plan the in-circuit programming flow carefully: OTP cells cannot be erased, so a programming error forces part scrappage. Place the ICSP clock/data/Vpp test points so a programmer can reach them after board assembly, and budget for a small adapter socket during pilot runs. The 44-pin TQFP also requires fine-pitch PCB layout - 0.8 mm pitch traces are standard but watch for solder bridging on the EP-adjacent pads.

Key features include 33 digital I/O pins, two 8-bit and three 16-bit timer/counter modules, a 5-channel 8-bit ADC, two analog comparators, a Universal Synchronous/Asynchronous Receiver/Transmitter (USART/SCI), a Serial Peripheral Interface (SPI), and an Inter-Integrated Circuit (I2C) bus. The OTP program memory allows one-time programming by the developer, distinguishing this part from UV-erasable EPROM variants. Operating voltage ranges from 4.0V to 6.0V, suiting 5V industrial and automotive designs. The PIC16C74B architecture employs a 14-bit instruction pipeline with an 8-level hardware stack, supporting interrupt-driven designs with prioritized vectored interrupts. Brown-out Reset (BOR) and Power-on Reset (POR) circuitry protect against unstable supply conditions, while the Watchdog Timer (WDT) with its own on-chip RC oscillator provides system recovery from software lockups - critical for automotive and industrial environments where firmware reliability is non-negotiable. Typical applications include automotive body electronics, industrial control subsystems, sensor interface modules, HVAC controllers, and legacy embedded systems requiring field-programmable OTP at production volume. The 20MHz instruction throughput and 5-channel ADC make it well-suited for closed-loop motor control and PID-based process regulation. When designing with the PIC16C74B, ensure the operating supply stays within 4.0V to 6.0V and that decoupling capacitors (typically 0.1uF ceramic) are placed within 5mm of VDD/SS pins. The PLCC-44 socket allows field replacement and in-circuit programming, but OTP memory means firmware must be fully verified before production programming.

The 28-pin SPDIP package allows easy through-hole prototyping on breadboards and development boards. The PIC16C76-04E/SP uses a Harvard architecture with separate program and data buses, RISC instruction set, and a hardware multiplier-free ALU optimized for byte and bit operations. The OTP memory is one-time programmable, meaning each device can be programmed exactly once with the application firmware, making this part ideal for low-to-medium volume production where the cost of Flash-based parts is not justified. Typical applications include industrial control systems, sensor interfacing, motor control, consumer appliances, security and alarm systems, and educational microcontroller platforms. The extended temperature range and robust CMOS design also suit outdoor and automotive under-hood environments. Because the PIC16C76 has been superseded by the Flash-based PIC16F76 in new designs, this OTP variant is most commonly used to maintain legacy production runs or to honor existing firmware compatibility constraints. When designing with this device, ensure that the chosen programmer supports the PIC16C7X OTP algorithm (e.g., PICSTART Plus, MPLAB PM3) and that the application firmware will not require field upgrades. Designers should also evaluate the PIC16F76 as a modern Flash-based alternative with in-circuit programmability.

PIC16C76-10/SO

PIC16C76-10/SO - 8-Bit 10MHz OTP MCU 14KB | Microchip

The Microchip Technology PIC16C76-10/SO is an 8-bit CMOS OTP-based microcontroller from the PIC16C7X mid-range family, delivering 10 MIPS at a 10 MHz clock in a 28-pin SOIC package. It integrates 14KB (8K x 14) of One-Time-Programmable program memory, 368 bytes of RAM, and 5 channels of 8-bit Analog-to-Digital conversion, with 22 digital I/O lines arranged across PORTA, PORTB, and PORTC. A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory, working RAM, and programmable I/O peripherals. The PIC16C76 belongs to the RISC microcontroller category (reduced instruction set computer), where most instructions execute in a single 200 ns instruction cycle. Within the broader taxonomy, it sits at: microcontroller -> embedded controller -> 8-bit MCU -> PIC mid-range -> PIC16C7X sub-family. This hierarchy matters for engineers selecting a drop-in alternative or evaluating migration paths to flash-based parts such as the PIC16F76. Key features include the synchronous serial port configurable as either 3-wire SPI or 2-wire I2C, a USART for asynchronous serial communication, two capture/compare/PWM modules, two 8-bit timers plus one 16-bit timer, and a wide 2.5V to 6.0V operating voltage range. The high sink/source current capability of 25/25 mA per pin allows direct drive of small relays, LEDs, and opto-isolators without external driver transistors, simplifying BOM in cost-sensitive designs. Architecturally, the PIC16C76 uses a Harvard-class RISC core with separate program and data buses, allowing instruction fetch and data access to occur in the same cycle. The OTP program memory is programmed once via Microchip's ICSP (In-Circuit Serial Programming) interface, after which the device cannot be reprogrammed. For development or production runs requiring field upgrades, the flash-based PIC16F76 is the recommended migration path with the same 28-pin SOIC pinout, same peripherals, and same instruction set. Typical applications include industrial control, motor control (small DC brushed), sensor interfacing with on-chip ADC, consumer appliance user interfaces, and embedded serial communications subsystems using SPI/I2C/USART. Its commercial temperature grade and 25 mA I/O drive suit it for legacy products, replacement designs, and long-life industrial installations. The OTP program memory makes it cost-optimized for high-volume, code-stable products rather than development prototyping. When designing with this device, note that OTP memory prohibits firmware updates after programming. Confirm code is fully debugged on a flash equivalent (such as PIC16F76-I/SO) before committing to OTP volume programming. The 10 MHz rating corresponds to 10 MIPS maximum instruction throughput; derate accordingly when calculating timer resolution or UART baud-rate error budgets at lower VDD. This page consolidates distributor pricing, lifecycle status, drop-in alternatives, and engineering design notes that the manufacturer datasheet alone does not provide, helping engineers and sourcing teams make faster decisions for production.

PIC16C76-10/SP

PIC16C76-10/SP - 8-Bit 10MHz OTP MCU 14KB Flash | Microchip

The Microchip Technology PIC16C76-10/SP is an 8-bit CMOS microcontroller from the PIC16C7x mid-range family, featuring 14KB of One-Time-Programmable (OTP) program memory, 368 bytes of RAM, and up to 22 digital I/O pins in a 28-pin SPDIP (Skinny Plastic DIP) through-hole package. Operating at a maximum clock of 10MHz, it delivers 5 MIPS of throughput, integrates a 5-channel 8-bit Analog-to-Digital Converter (ADC), and provides a Universal Asynchronous Receiver/Transmitter (USART) for serial communications. An 8-bit microcontroller (MCU) is a single-chip computer that combines a CPU, program memory (ROM/OTP/Flash), data RAM, and peripheral interfaces onto one silicon die. The PIC16C76 belongs to the broader PIC16CXX mid-range architecture family - a Harvard-architecture processor group used widely in industrial control, consumer appliances, and instrumentation. The mid-range family sits hierarchically between PIC baseline 8-bit parts and PIC18 8-bit enhanced parts, offering a balance of cost, peripheral integration, and C-assembly programmability. Key features of the PIC16C76-10/SP include two 8-bit timers plus one 16-bit timer, two Capture/Compare/PWM (CCP) modules for motor and lighting control, a synchronous serial port configurable as 3-wire SPI or 2-wire I2C, and a USART for RS-232/RS-485 links. The integrated 8-bit ADC with 5 input channels eliminates the need for an external converter in many sensor-interface designs. The 10MHz oscillator enables a 200ns instruction cycle, sufficient for control loops up to a few kHz and human-interface response. The architecture uses a 14-bit instruction word with separate program and data buses (Harvard architecture), allowing simultaneous instruction fetch and data access. The OTP memory is programmed once and cannot be erased - making the part well-suited to high-volume production where code is final. Industrial and extended temperature grades (-40C to +85C or +125C) support harsh-environment deployment, though the SP suffix here denotes the standard SPDIP package, not a temperature grade. Typical applications include industrial control panels, appliance controllers, simple sensor hubs, automotive body electronics (legacy), HVAC thermostats, and instrumentation front-ends. The USART, SPI/I2C, and CCP peripherals cover most communication and actuator needs in these embedded designs. When designing with the PIC16C76-10/SP, note that OTP requires one programming pass per device; for prototyping or field-upgradable firmware, choose the flash-based PIC16F76 equivalent in the same 28-pin SPDIP package. Place a 100nF decoupling capacitor adjacent to VDD and reserve the MCLR pin for a proper reset network to avoid spurious resets in electrically noisy environments. This page synthesizes distributor pricing, drop-in alternative listings from the PIC16C7x family, and practical design notes not aggregated on a single manufacturer or distributor page - giving engineers a one-stop reference for sourcing and substituting the PIC16C76-10/SP.

The part delivers 200ns instruction execution, supports 35 single-word instructions, and is pin-compatible with the PIC16C5X and PIC12CXXX lines. A microcontroller (MCU) is a single-chip computer containing a CPU, program memory, data RAM, peripherals and I/O. The PIC16C7X family adds integrated analog and serial peripherals to the mid-range core, reducing external component count. PIC16C76 specifically targets applications that need on-chip ADC plus SPI/I2C/USART connectivity. Compared with modern PIC16F Flash parts it trades reprogrammability for lower unit cost in high-volume, code-stable products. Key features include 5 channels of 8-bit ADC, 2 additional timers, 2 capture/compare/PWM modules, a synchronous serial port configurable as 3-wire SPI or 2-wire I2C, a USART, and 22 digital I/O pins. The 10MHz oscillator drives a 4-state pipeline that yields a 10 MIPS instruction throughput. The "-10I" suffix indicates 10MHz maximum frequency and the industrial -40C to +85C temperature range, while "/SO" denotes the 28-pin 7.50mm-wide SOIC package. The architecture combines a RISC Harvard CPU with a 14-bit instruction word and an 8-bit data path. Peripherals share a common interrupt structure and are addressed through banked SFRs. The OTP program memory is programmed once at production time, which is why Microchip recommends PIC16F76 for new designs and prototype runs. Typical applications include industrial process control nodes, building automation sensor interfaces, motor control signal conditioning, low-cost consumer appliance controllers, and educational/development boards where the well-documented mid-range instruction set simplifies firmware development. When designing with this device, verify the OTP programming flow against your production test strategy, because OTP parts cannot be reprogrammed if a code bug is discovered after the part is sealed. For prototyping or field-upgradable firmware, evaluate PIC16F76-I/SO, which shares the same 28-SOIC footprint and pinout but uses Flash memory.

The device executes instructions at 200 ns per cycle from a 10 MHz external oscillator and provides 22 digital I/O lines, five 8-bit A/D converter channels, two capture/compare/PWM modules, and a synchronous serial port configurable as SPI or I2C, plus a USART for asynchronous serial communication. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripheral interfaces onto one silicon die. The PIC16C7X family uses Microchip's RISC architecture with only 35 single-word instructions, which simplifies code development and produces deterministic interrupt latency ideal for real-time control loops. PIC microcontrollers sit in the broader hierarchy of 8-bit microcontrollers, embedded processors, and semiconductor ICs, and remain popular for cost-sensitive, deterministic industrial and consumer applications. Key features include OTP (One-Time-Programmable) program memory for prototype and low-volume production, an industrial-grade operating temperature range of -40C to +85C (the "I" suffix), and a 4V to 5.5V single-supply rail. The five-channel 8-bit ADC enables mixed-signal sensing without an external converter, and the two PWM modules support direct motor or power-converter control. The integrated USART and master-slave SPI/I2C ports simplify connectivity to sensors, displays, and other MCUs. The PIC16C76 architecture uses a Harvard-style bus with separate program and data paths, allowing instruction fetch and operand read in a single cycle. OTP memory is programmed once and is non-erasable, which lowers unit cost compared to flash-based devices for high-volume sealed units but requires flash-based PIC16F76 for field-upgradable designs. According to Microchip, the PIC16F76 is the recommended newer replacement with flash memory and the same pinout. Typical applications include industrial control boards, appliance motor control, sensor interface front-ends, simple human-machine interface panels, and embedded serial communication gateways. Designers use this part where deterministic response, low cost, and OTP code protection outweigh the need for in-system reprogramming. When designing with PIC16C76-10I/SP, reserve the MCLR pin for an external reset circuit and follow Microchip's recommended decoupling practice of a 0.1 uF ceramic capacitor on VDD placed within 5 mm of the pin. For new designs, evaluate the flash-based PIC16F76-I/SP which retains the same pinout and peripheral set but adds ISP (in-system programming) and reprogrammability.

PIC16C76-20/SP - 8-Bit 20MHz OTP MCU, 14KB EPROM, 28-SPDIP | Microchip

The Microchip Technology PIC16C76-20/SP is a member of the PIC16C7X mid-range family of 8-bit CMOS microcontrollers, integrating 14KB of one-time programmable (OTP) program memory with 368 bytes of RAM in a 28-pin SPDIP (Skinny Plastic DIP) through-hole package. It executes instructions at 20MHz (200 ns instruction cycle) and embeds 5 channels of 8-bit A/D conversion, 2 capture/compare/PWM modules, a synchronous serial port configurable as either SPI or I2C, and a USART for asynchronous serial communication. The /SP suffix denotes a 28-pin SPDIP commercial-temperature-grade part, while the -20 suffix indicates 20MHz maximum clock frequency. A PIC16C76 is an 8-bit microcontroller built on Microchip's PIC RISC architecture, which belongs to the broader microcontrollers (MCU) category in the integrated-circuits hierarchy. PIC MCUs are microcontrollers -> embedded processors -> semiconductors. The 16C76 specifically sits within the PIC16C mid-range family, which combines Harvard-architecture RISC performance with rich peripheral integration including analog-to-digital converters, making it suitable for mixed-signal embedded control rather than purely digital logic. Key features that differentiate the PIC16C76 include 22 digital I/O lines, 25 mA source/sink per I/O (suitable for direct LED drive), wide 2.5V-6.0V operating voltage, and 8-bit A/D conversion on 5 input channels with multiplexed sampling. The device supports both commercial (0C to +70C) operating ranges and integrates power-management features such as low-power standby (15 uA typical at 5V/4MHz, 1 uA at 3V/32kHz). The PIC16C76 also supports in-circuit serial programming (ICSP) via two pins, simplifying field firmware updates without part removal. Architecturally, the PIC16C76 uses a 14-bit instruction word with a 35-instruction RISC set, 8-level deep hardware stack, and direct/indirect addressing modes. The integrated analog peripherals share pins with digital I/O via configuration registers, and the SSP module can be software-switched between SPI master/slave and I2C master/slave modes, providing flexible bus connectivity. Power-on reset, brown-out detect, watchdog timer, and code protection features are all standard. Typical applications include industrial control logic, sensor signal conditioning with on-chip ADC, motor drive PWM control loops, low-cost consumer appliances with serial display or remote control interfaces, and embedded data-acquisition front-ends. The 28-pin SPDIP package remains popular for prototype development, educational kits, and legacy industrial designs that require through-hole soldering. Designers should plan around OTP memory constraints: code cannot be erased or rewritten, so production firmware must be fully validated before programming. Use ICSP for prototyping with windowed (JW) variants and migrate to OTP only once firmware is frozen. For new designs, consider flash-based PIC16F76 or PIC18F equivalents unless OTP cost advantage or non-volatility-without-flash is required.

The Microchip Technology PIC16C76-20I/SO is an 8-bit CMOS mid-range microcontroller built around a high-performance RISC core, delivering 20 MHz operation, 14 KB of one-time-programmable (OTP) program memory, and 368 bytes of RAM in a 28-pin SOIC (SO) package. The 'I' suffix denotes the industrial operating temperature range, and the '20' speed grade confirms 20 MHz maximum clock. The device integrates a 5-channel 8-bit ADC, two 8-bit timers plus one 16-bit timer, dual capture/compare/PWM modules, a synchronous serial port configurable for either 3-wire SPI or 2-wire I2C, and a USART for asynchronous serial communication. A microcontroller (MCU) is a single-chip computer containing a processor core, non-volatile program memory, working RAM, and integrated peripherals such as timers, ADCs, and communication interfaces. The PIC16C76 sits within the broader hierarchy: microcontroller -> 8-bit MCU -> mid-range PIC16 family -> PIC16C7X sub-family. Unlike flash-based MCUs, OTP memory is programmed once via a device programmer and cannot be erased, which makes OTP parts economical for mature production runs where firmware is stable.

The /SP suffix denotes a 28-pin 0.300-inch SPDIP package and the -20 suffix specifies a 20 MHz maximum clock rate. What is an 8-bit OTP microcontroller? An 8-bit OTP (One-Time-Programmable) microcontroller is a single-chip computer built around an 8-bit data path and program memory that can be written exactly once using an external programmer. The PIC16C76 sits in Microchip's mid-range PIC16CXX family, which belongs to the broader PIC microcontrollers taxonomy (8-bit MCU -> microcontroller -> embedded controller -> semiconductor).

The part draws a few mA active and supports low-power sleep mode for battery-aware applications. The 5-channel 8-bit ADC eliminates external signal-conditioning ICs in many sensor-reading designs, while the USART/SPI/I²C peripherals enable direct connection to sensors, displays, EEPROMs, and other digital ICs. Technical depth: the PIC16C76 uses a Harvard architecture with separate program and data buses, which lets instruction fetch and data access occur in the same cycle. Its 14-bit instruction word and 8-bit data word provide a good code-density trade-off for control-oriented firmware, and the integrated peripheral set keeps BOM cost low for industrial control, instrumentation, and appliance applications. Typical applications include industrial control systems, sensor signal conditioning, HVAC controllers, motor control drivers, instrumentation front-ends, and embedded designs migrating from PIC16C7x predecessors. The wide peripheral mix means a single PIC16C76 can handle analog sensing, digital I/O, and serial communication without external glue logic. When designing with this device, ensure the MCLR reset circuit follows Microchip's recommended RC time constant, place decoupling capacitors within 5 mm of each power pin, and respect the maximum 20 MHz oscillator frequency at the chosen VDD. Note that OTP memory cannot be erased, so production code must be fully validated before programming.

PIC16C76/JW - 8-Bit 20MHz 14KB EPROM MCU 28-CDIP | Microchip

The Microchip Technology PIC16C76/JW is an 8-bit CMOS RISC microcontroller with 14KB (8K x 14) of one-time-programmable / UV-erasable EPROM program memory, 368 bytes of data RAM, and 22 digital I/O lines, housed in a 28-pin Ceramic DIP (CERDIP-28, JW) windowed package for through-hole mounting. The JW suffix denotes the quartz window on top of the package that allows EPROM erasure by exposure to ultraviolet light, enabling repeated re-programming during development and prototyping. According to the manufacturer product page, the device executes 35 single-word instructions at 200 ns per instruction cycle at 20 MHz clock input, supporting high-performance RISC architecture with all instructions single-cycle except program branches (two cycles). An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, data RAM, I/O peripherals, and timers onto one silicon die. The PIC16C76/JW belongs to Microchip's PIC16C7X mid-range family, which sits within the broader PIC16 architecture hierarchy: PIC16 mid-range -> 8-bit MCU -> microcontroller -> embedded controller -> semiconductor. The device features 5 channels of 8-bit Analog-to-Digital (A/D) converter, two additional timers, 2 capture/compare/PWM (CCP) modules, a synchronous serial port configurable as 3-wire SPI or 2-wire I2C, and a Universal Asynchronous Receiver Transmitter (USART) for asynchronous serial communication. Key differentiating features include 25 mA source/sink current per I/O pin for direct LED and power-transistor drive, wide operating voltage range from 2.5V to 6.0V, low power consumption of 15 uA typical at 5V/4 MHz and 1 uA typical standby at 3V/32 kHz, plus commercial, industrial and extended temperature ranges. The PIC16C76/JW is the windowed ceramic-package variant used in development, prototyping, and low-volume production; the OTP and flash variants (PIC16C76, PIC16F76) share the same die and pinout. The JW CERDIP-28 package is recommended when in-circuit UV erasure is required between firmware revisions. Typical applications include industrial automation and control systems, instrumentation and data acquisition, sensor signal conditioning, motor control via the CCP/PWM modules, embedded serial communication links, and any design requiring repeated firmware iteration during development. The wide supply range and high sink/source current make it well suited to drive relays, LEDs, and small solenoids directly without external drivers. Per the manufacturer cross-reference note, a newer flash-based replacement PIC16F76 is recommended for new designs. When designing with this device, place a 0.1 uF decoupling capacitor close to VDD and use the JW package only when UV erasure is needed; otherwise prefer the plastic PDIP/SOIC variants for production. Note that this is a One-Time-Programmable / UV-EPROM legacy device, not a flash MCU; erase cycles require UV exposure through the JW window.

PIC16C765-I/L - 8-Bit USB MCU, 14KB OTP, 24MHz | Microchip

The Microchip Technology PIC16C765-I/L is an 8-bit CMOS RISC microcontroller with integrated USB 1.1 full-speed peripheral support, 14 KB (8K x 14) of One-Time-Programmable (OTP) program memory and 256 bytes of RAM, housed in a 44-pin PLCC package. It executes instructions in 167 ns (24 MHz clock) and offers 33 digital I/O lines, an 8-channel 8-bit ADC, and a USB Serial Interface Engine (SIE) compliant with USB low-speed and full-speed signalling. The PIC16C765 belongs to the PIC16CXX mid-range family — a category of 8-bit microcontrollers that pair a Harvard RISC core with a compact instruction set of 35 single-word instructions. PIC16CXX devices serve as the mainstream embedded controllers in Microchip's portfolio, sitting hierarchically between 8-bit baseline PIC10/12/16 cores and 16-bit PIC24/dsPIC parts, and are widely used in USB-class human-interface and consumer peripherals. Key features include five 8-bit A/D converter channels (note: secondary sources list 5 muxed channels of an 8-channel ADC), two 8-bit timer/counters and one 16-bit timer/counter, a Universal Synchronous/Asynchronous Receiver-Transmitter (USART) with SPI master-mode support, an eight-level-deep hardware stack, and multiple internal/external interrupt sources. The OTP program memory allows prototype and low-volume production programming without windowed UV erasure. Architecturally the device integrates the USB transceiver and SIE directly on-die, eliminating external USB transceivers or protocol firmware stacks for basic interrupt, bulk and control transfers. The 33 I/O pins are 5 V-tolerant and source/sink up to 25 mA per pin, making them capable of directly driving LEDs and small relays without external buffers. Typical applications include USB mice, keyboards, joysticks, USB-to-serial bridges, game controllers, USB HID-class peripherals, point-of-sale terminals, and industrial USB sensor interfaces where a low-cost, USB-capable 8-bit MCU with OTP flexibility accelerates development. When designing with this part, note that the OTP memory cannot be re-programmed in-circuit: a windowed CERDIP variant (PIC16C765-JW) is required for code iteration. Also budget for the 24 MHz crystal required by the USB peripheral to meet the 1.5 Mb/s / 12 Mb/s timing tolerances.

PIC16C765-I/P

PIC16C765-I/P - 8-bit USB MCU, 14KB OTP, 24MHz, 40-PDIP | Microchip

The Microchip Technology PIC16C765-I/P is an 8-bit CMOS OTP-based microcontroller in the PIC16CXX mid-range family with integrated full-speed USB 1.1 (12 Mbps) peripheral support, 14KB of OTP program memory (8K x 14 words), 256 bytes of data RAM, and 33 digital I/O lines, all housed in a 40-pin PDIP through-hole package rated for the industrial temperature range (-40C to +85C). What is a PIC microcontroller? A PIC microcontroller is a family of reduced instruction set computing (RISC) microcontrollers from Microchip Technology based on a Harvard architecture with separate program and data buses. The PIC16C series specifically represents the original OTP (one-time-programmable) mid-range line, executed at 167 ns per instruction cycle (6 MHz oscillator / 4) up to 24 MHz, which delivers roughly 6 MIPS of throughput - a mid-range category in the broader hierarchy of microcontroller -> embedded controller -> semiconductor device. Key differentiating features include 5 channels of 8-bit analog-to-digital conversion, a full-speed USB 1.1 serial interface engine (SIE) with on-chip transceiver, hardware USART, MSSP (I2C/SPI) peripheral, two 8-bit timers and one 16-bit timer, 14 interrupt sources, and a 35 single-word instruction RISC instruction set. Power-saving features include SLEEP mode, watchdog timer with its own on-chip RC oscillator, and programmable code protection. Architecturally, the device uses a 14-bit instruction word with an 8-bit data path, executing one instruction per cycle except for program branches which take two cycles. The USB SIE handles low-level protocol including NRZI encoding, bit stuffing, and CRC checking, freeing the CPU from timing-critical tasks. Brown-out detect, power-on reset, and a wide operating voltage range of 4.0V to 5.5V complete the robust feature set. Typical applications include low-speed USB human interface devices such as HID-class keyboards, mice, and game controllers, industrial USB-to-serial bridges, USB-based data acquisition front-ends, legacy embedded systems requiring one-time-programmable firmware, and educational/prototyping platforms where the 40-pin PDIP package simplifies breadboard use. When designing with this part, note that the OTP memory cannot be erased and reprogrammed - engineers targeting field-updatable firmware should select the flash-based PIC18F or PIC16F equivalents. The 40-pin PDIP package also requires through-hole PCB assembly which limits high-volume SMT production.

PIC16C765-I/PT

PIC16C765-I/PT - 8-Bit USB MCU, 14KB OTP, 44-TQFP | Microchip

The Microchip Technology PIC16C765-I/PT is an 8-bit CMOS OTP-based microcontroller from the PIC16CXX mid-range family, integrating a full-speed USB 1.1 device interface, 14KB of one-time-programmable program memory, 256 bytes of data RAM, and a 5-channel 8-bit ADC in a 44-pin TQFP (PT) package. It executes 35 single-word instructions at 24 MHz with a 167 ns instruction cycle, delivering up to 6 MIPS of throughput while keeping code density high and toolchain overhead low. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and configurable peripherals. The PIC16C765 belongs to Microchip's mid-range 8-bit PIC family, which sits in the broader taxonomy of microcontroller -> embedded processor -> semiconductor. Mid-range PICs are widely adopted for cost-sensitive, deterministic control tasks because of their compact instruction set, predictable interrupt latency, and a mature MPLAB X toolchain. Key features include a USB 1.1 full-speed (12 Mbps) device transceiver compliant with the USB 2.0 specification, an 8-level hardware stack, 33 digital I/O lines, two 8-bit timers and one 16-bit timer, a USART, and an 8-bit successive-approximation ADC with five input channels. The OTP program memory allows one-time field programming suitable for production-grade firmware, while an in-circuit debugger (ICD) interface is supported via the standard Microchip ICSP pinout. Typical applications include low-speed USB human-interface devices (HID) such as keyboards, mice, and game controllers, USB-to-UART bridges, industrial instrumentation front-ends with local ADC scanning, and legacy embedded control boards that benefit from on-chip USB without external transceivers. When designing with this device, note that the OTP memory cannot be re-programmed in-circuit, so a windowed CERDIP (JW) variant is required for code development; the 44-TQFP footprint also exposes several pins shared between analog and digital functions, requiring careful pin allocation in mixed-signal layouts. This page synthesizes distributor pricing, drop-in same-family Microchip alternatives, cross-family comparison data, and practical design notes that are not collected in any single manufacturer datasheet.
