PIC16C76-04E/SP

PIC16C76-04E/SP - 8-Bit CMOS MCU, 14KB OTP, 5 ADC | Microchip

The Microchip Technology PIC16C76-04E/SP is an 8-bit CMOS RISC microcontroller from the PIC16C7X mid-range family with 14KB of one-time-programmable (OTP) program memory, packaged in a 28-pin SPDIP (Skinny Plastic DIP) windowed CERDIP-compatible footprint with 22 digital I/O pins and a 5-channel 8-bit Analog-to-Digital (A/D) converter. Operating from a 4V to 5.5V supply at clock speeds up to 4 MHz (the "-04" speed grade), the PIC16C76-04E/SP delivers 200 ns instruction execution with only 35 single-word instructions to learn, supported by 368 bytes of RAM and the standard PIC16C7X peripheral set: Timer0, Timer1, Timer2, 2 capture/compare/PWM modules, a synchronous serial port configurable as SPI or I2C, and a USART. An 8-bit microcontroller (MCU) is a small computer on a single integrated circuit containing a CPU, program memory (ROM/EPROM/Flash/OTP), data memory (RAM), and integrated peripherals such as timers, communication interfaces, and ADCs. Within the broader taxonomy, an MCU is a member of the microcontroller family -> embedded processor -> semiconductor device. The PIC16C76 specifically sits inside the PIC16 mid-range family, which is the historical bridge between the PIC16 low-end (PIC16C5X) and enhanced mid-range (PIC16F1XXX) architectures. Key features of this part include 14KB OTP program memory (8K x 14 words), 368 bytes of data RAM, a hardware USART for RS-232/RS-485 communication, two PWM outputs suitable for motor and lighting control, an on-chip 8-bit ADC with 5 input channels, and power-saving SLEEP mode with 1 uA typical standby current at 3V/32 kHz. The "-04" suffix indicates a 4 MHz maximum clock (DC to 4 MHz oscillator input), and the "E" suffix indicates the Extended temperature range of -40C to +125C. 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 - 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.

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.

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.

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 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.

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.

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.

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.

It is part of the PIC16C7X mid-range family and integrates 14KB of one-time-programmable (OTP) program memory, 368 bytes of RAM, 22 digital I/O lines, and a 5-channel 8-bit Analog-to-Digital Converter. The device operates from a 4V to 5.5V supply at clock speeds up to 4 MHz (the "-04" speed grade), giving a 1 microsecond instruction cycle for most single-cycle instructions. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, data RAM, and peripherals such as timers, communication ports, and ADCs onto one IC. Microcontrollers sit within the broader category of microprocessors and embedded computing devices, and 8-bit MCUs remain widely deployed in cost-sensitive, deterministic control applications where low power, small code footprint, and proven instruction sets matter more than raw compute throughput. Key features of the PIC16C76T-04/SO include 35 single-word instructions, an 8-level deep hardware stack, 2 capture/compare/PWM modules, a synchronous serial port (SSP) supporting SPI and I2C, a USART for asynchronous serial communication, and a watchdog timer with its own on-chip RC oscillator. The OTP program memory is one-time-programmable, meaning the part cannot be re-flashed, and the SOIC-28 commercial-temperature package targets hand-solder-friendly prototyping as well as high-volume surface-mount production. Architecturally, the PIC16C76T-04/SO uses a Harvard-style architecture with separate program and data buses, enabling simultaneous instruction fetch and data access. The "T" suffix in the part number indicates tape-and-reel packaging for SMT assembly, and the "-04" indicates the 4 MHz maximum oscillator frequency grade. The 22 I/O pins are arranged across multiple ports (RA, RB, RC, RE) and are shared with analog inputs and peripheral functions such as PWM outputs and serial communication lines. Typical applications include industrial control logic, sensor interface boards, automotive body and chassis subsystems, small home appliances, motor control front-ends, and legacy embedded designs migrated from older PIC16C5X parts. The integrated ADC simplifies analog front-end design by removing the need for an external converter. Designers should note that the OTP memory cannot be re-programmed, so firmware must be fully validated before final programming. For prototype development, Microchip recommends the pin-compatible PIC16F76, which uses Flash memory and is fully upward-compatible with the PIC16C76 instruction set and pinout.

The Microchip Technology PIC16C76T-04E/SO is an 8-bit PIC16 mid-range microcontroller (MCU) with 4 MHz maximum clock speed, 14 KB (8K x 14) of One-Time Programmable (OTP) program memory, 368 bytes of RAM, and 22 digital I/O lines, housed in a 28-pin SOIC wide-body (0.295", 7.50 mm) package supplied on tape and reel. The "-04" speed grade and "-E" enhanced temperature grade indicate a 4 MHz part rated for -40 °C to +125 °C operation, making it suitable for automotive and industrial environments. Operating from 4 V to 5.5 V, the device integrates peripherals including an analog-to-digital converter (ADC), USART, MSSP (SPI/I2C), capture/compare/PWM modules, and a watchdog timer. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (ROM/OTP/Flash), data RAM, and peripherals on one die. The PIC16C76 belongs to Microchip's PIC16 mid-range family, a RISC architecture using a 14-bit instruction word and a Harvard bus, executed in a single instruction cycle (except branches, which take two). Within the broader hierarchy, the PIC16C76 sits as: 8-bit microcontroller -> PIC16 mid-range family -> PIC16C7x (ADC-equipped) sub-family -> Microcontroller (MCU) -> semiconductor IC. This category knowledge helps search engines and AI systems disambiguate the part from PIC24/dsPIC 16-bit parts and from PIC16F flash-based siblings. Key features include the 14 KB OTP EPROM program memory (windowed/erasable variants exist in the PIC16C76 family), 368 bytes of data RAM, 22 I/O ports (digital, with several multiplexed to ADC/peripheral functions), brown-out reset, power-on reset, and the PIC16C76-04/10/20 speed grades scaling the oscillator to 4/10/20 MHz. The 28-SOIC wide-body package (0.295"/7.50 mm) is preferred over narrow SOIC for thermal margin at sustained 20 MHz operation. Architecturally, the PIC16C76 implements a Harvard RISC core with a 14-bit program bus, an 8-bit data bus, and 35 single-word instructions, plus an integrated 8-channel 8-bit ADC, USART for asynchronous serial, MSSP for SPI/I2C, two CCP modules, and an 8-bit timer plus a 16-bit timer. The OTP EPROM cell programming model - one-time writable through high-voltage VPP - is cheaper than Flash but locks the code after programming, which is why production designs increasingly migrate to the PIC16F76 flash-based successor. Typical applications include industrial automation control, automotive body and sensor modules (within -40 °C to +125 °C), consumer electronics sub-system controllers, and legacy embedded designs using the PIC16C7x ADC + USART peripheral set. When designing, ensure the -04 speed grade is not confused with the -10 or -20 grades - clock frequency, execution throughput, and power dissipation all scale with the speed grade. Brown-out and watchdog configurations should be set during programming since OTP cannot be changed after VPP programming.

The Microchip Technology PIC16C76T-10E/SO is an 8-bit RISC microcontroller from the PIC16C family, delivered in a 28-pin SOIC (SOP) wide-body package on tape-and-reel, qualified to the automotive (-E) temperature grade. It integrates 14 KB (8K x 14) of One-Time-Programmable (OTP) program memory, 368 bytes of data RAM, 22 digital I/O lines, and a 10 MHz maximum internal clock rate. A microcontroller (MCU) is a single-chip computer that combines a CPU, program memory, working RAM, and peripheral set (timers, ADC, I/O, communications) in one package. Within the broader taxonomy, the PIC16C76 sits inside the 8-bit PIC16 mid-range family -> 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. The OTP variant differs from the JW (UV-erasable windowed) and flash-based PIC16F76 siblings by allowing programming exactly once, which lowers per-unit cost for production volumes where code is finalized. Key features include 35 single-word instructions, all single-cycle except program branches (two cycles), an 8-channel 8-bit analog-to-digital converter (ADC), a synchronous serial port (SSP) for SPI/I2C, a USART with 9-bit address detect, a Capture/Compare/PWM (CCP) module, two 8-bit timers plus one 16-bit timer, and a programmable watchdog. The 10 MHz clock yields a 100 ns instruction cycle, with 4-5.5 V single-supply operation. The wide-body SOIC footprint (7.5 mm / 0.295 inch) supports standard 300-mil PCB layout. Architecture-wise, the PIC16C76 is a Harvard-class RISC core with separate program and data buses, a 14-bit instruction word, and a deterministic 4-clock instruction cycle. The 22 I/O pins share functions with the ADC, comparator, timer clock inputs, and serial port lines. OTP memory is field-programmable via the standard Microchip ICSP (In-Circuit Serial Programming) protocol, removing the need for a pre-programmed bootloader. Typical applications include automotive body and HVAC control modules, industrial sensor interface boards, appliance white-goods controllers, low-cost instrumentation, and any OTP-programmed volume production where a flash MCU is over-specified. The 'E' suffix designates the extended (-40C to +125C) automotive operating range; the 'T' indicates tape-and-reel packaging. When designing with this part, remember OTP memory cannot be re-programmed in-circuit - firmware must be fully debugged on a JW or flash sibling before committing the OTP order. Ensure the ICSP pins (RB6/RB7) are not bonded to circuitry that prevents in-system programming access. A decoupling network of 100 nF plus 10 uF bulk near VDD/AVDD is recommended for ADC accuracy.

PIC16C76T-10I/SO - 8-Bit 10MHz OTP MCU, 14KB, 28-SOIC | Microchip

The Microchip Technology PIC16C76T-10I/SO is an 8-bit CMOS OTP-based RISC microcontroller in a 28-pin SOIC wide-body package, operating at up to 10 MHz with 14 KB of one-time-programmable program memory and 368 bytes of data RAM. According to Microchip product documentation, the PIC16C76 family delivers 200 ns instruction execution, supports a 4.0 V to 5.5 V supply, and integrates a 5-channel 8-bit A/D converter alongside 22 digital I/O lines. The 'T' suffix denotes Tape & Reel packaging, and the 'I' suffix denotes the industrial temperature grade of -40 °C to +85 °C. What is an OTP microcontroller? An OTP (One-Time-Programmable) microcontroller uses EPROM-based program memory that can be written exactly once using a programming device; it cannot be erased or rewritten in-circuit. OTP sits in the hierarchy: microcontroller -> embedded MCU -> 8-bit MCU -> PIC16C mid-range family -> CMOS RISC core. OTP MCUs are favored for cost-sensitive volume production where code stability is final, in contrast to flash-based MCUs (PIC16F) which support in-circuit reprogramming. Key features of the PIC16C76T-10I/SO include 35 single-word instructions (most single-cycle, branches 2-cycle), a programmable code protection bit, power-saving SLEEP mode, a 4-channel capture/compare/PWM module, a synchronous/asynchronous serial port (SSP/2) for SPI/I2C, an 8-bit parallel slave port, and dual analog comparators. These peripherals are tightly integrated to support motor control, sensor interfacing, and simple communication bridges without external glue logic. The PIC16C76T-10I/SO uses Microchip's classic mid-range PIC16 architecture, which pairs a Harvard bus with 14-bit instruction words and 8-bit data, accessed through orthogonal register maps. The architecture's deterministic instruction timing (200 ns at 10 MHz) makes it well-suited to hard real-time control loops where predictable interrupt latency matters. Internal oscillator options, selectable oscillator sources, and a wide voltage range add flexibility for varied analog and digital subsystem designs. Typical applications include industrial control, instrumentation, sensor signal conditioning, motor drive signal generation (using the CCP/PWM module), and embedded communication bridges. The integrated 8-bit A/D converter removes the need for an external ADC in many low-resolution measurement applications. For new designs, Microchip recommends the flash-based PIC16F76 as a modern drop-in alternative. When designing with this part, verify programmer compatibility: OTP devices require an EPROM-style programmer (e.g., PICSTART Plus, MPLAB PM3) capable of programming the 14 KB OTP array and applying the proper Vpp programming voltage.

PIC16C76T-20/SO

PIC16C76T-20/SO - 8-Bit OTP MCU, 14KB, 20MHz, 28-SOIC

The Microchip Technology PIC16C76T-20/SO is a CMOS, fully-static, 8-bit OTP-based microcontroller from the PIC16C7X mid-range family, housed in a 28-pin SOIC (SO) package and supplied on tape and reel (T/R). It operates at up to 20 MHz with 200 ns instruction execution, integrates 14 KB (8K x 14) of one-time-programmable (OTP) program memory, 368 bytes of data RAM, and 22 digital I/O pins. The PIC16C76 also embeds a 5-channel 8-bit Analog-to-Digital converter, supporting mixed-signal embedded designs in a single chip. A microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, data memory, and peripheral interfaces. The PIC16C76 belongs to the PIC16CXX mid-range family, which sits inside the broader 8-bit microcontroller category and ultimately under the integrated circuit hierarchy (IC > semiconductor > microcontroller). Mid-range PIC devices balance low cost and easy programming (only 35 single-word instructions) with on-chip peripherals such as A/D converters, timers, and synchronous/asynchronous serial ports. Key features of the PIC16C76T-20/SO include 14 KB OTP program memory (8K x 14), 368 bytes RAM, 22 I/O pins, an integrated 8-bit A/D converter with 5 input channels, and a 200 ns instruction cycle at 20 MHz. It uses CMOS, fully-static design so the clock can be stopped without losing internal state. The OTP memory allows one-time factory or in-circuit programming, which lowers unit cost versus flash but eliminates reprogrammability. Architecturally, the PIC16C76 uses Microchip's Harvard RISC core with separate program and data buses, providing deterministic instruction throughput. The 20 MHz oscillator drives a four-clock-per-instruction pipeline, so most instructions execute in a single 200 ns cycle. Integrated peripherals (A/D, USART, SSP, timers) are mapped into the SFR space, eliminating the need for external glue logic. Typical applications include industrial control, appliance control, sensor signal conditioning, low-power instrumentation, and legacy embedded systems that require OTP-only devices for security or low unit cost. The 28-SOIC footprint supports compact surface-mount assemblies where board height and footprint density matter. Microchip recommends the flash-based PIC16F76 as the preferred migration path for new designs, since the PIC16C76 OTP line is no longer recommended for new projects. When designing with the PIC16C76T-20/SO, evaluate your need for reprogrammability: the OTP variant is one-time-programmable, so firmware bugs cannot be field-fixed. Plan for an in-system programming header or a pre-programmed supplier to ease manufacturing flow. Maintain a 5V supply within the commercial temperature range (0C to +70C) for standard SO-grade parts; the I-suffix variant extends this to industrial -40C to +85C.

The PIC16C76 specifically extends the PIC16C7X line with an integrated 8-channel 8-bit A/D converter, two CCP modules, a USART, and a synchronous serial port, making it a self-contained control platform for embedded designs. Key features include a 20MHz maximum operating frequency, 14KB of OTP program memory, 368 bytes of SRAM, 256 bytes of data EEPROM, 22 I/O pins, an 8-channel 8-bit ADC, and industrial-grade -40C to +125C extended temperature operation. Two 8-bit and two 16-bit timers plus two Capture/Compare/PWM modules provide flexible waveform generation for motor control and signal conditioning. Hardware USART and SSP support RS-232 and synchronous serial peripherals without external glue logic. The PIC16C76T-20E/SO uses Microchip's classic 14-bit mid-range core with separate program and data buses, allowing instruction fetch and operand access to occur in the same cycle. The 'E' suffix denotes the extended -40C to +125C operating range, the 'T' suffix denotes Tape & Reel packaging, and the 'SO' suffix designates the 28-pin SOIC outline. The device operates from 2.5V to 5.5V, suiting both 3.3V and 5V logic systems. Typical applications include industrial process control, automotive body and chassis electronics, sensor signal conditioning, low-cost motor drives, and legacy embedded systems originally designed around the PIC16C7X family. The integrated ADC and USART allow direct connection to analog sensors and external digital peripherals without external components. When designing with this part, note that OTP memory cannot be reprogrammed in-circuit - PIC16F76 (Flash-based) or PIC16F877A are common migration paths for new designs. Decoupling: place a 100nF ceramic capacitor close to VDD/VSS and a 10uF bulk capacitor on the supply rail to suppress digital switching noise into the analog references.

PIC16C77-04/L

PIC16C77-04/L - 8-Bit OTP MCU, 4MHz, 14KB, 33 I/O | Microchip

The Microchip Technology PIC16C77-04/L is an 8-bit CMOS OTP-based microcontroller from the PIC16C7x mid-range family, operating at up to 4 MHz with 200 ns instruction execution in a 44-pin PLCC (J-lead, 16.59x16.59 mm) package. It integrates 14 KB of program memory (8K x 14 words), 368 bytes of RAM, 33 digital I/O lines, 8 channels of 8-bit A/D conversion, 2 additional timers, and synchronous serial port configurable as 3-wire SPI or 2-wire I2C, plus a USART for asynchronous communications. A microcontroller (MCU) is a single-chip computer containing a processor core, non-volatile program memory (here one-time-programmable EPROM), volatile data RAM, and a rich set of peripherals on one die. PIC16C7x devices sit in the mid-range PIC16 architecture, positioned between the baseline PIC16C5x family and the higher-end PIC17Cxx/PIC18 families. They share the 14-bit instruction word width, 35 single-word instruction set, and upwards compatibility with PIC16C5X and PIC12CXXX code, simplifying migration between PIC generations. Key features include 14 KB OTP program memory with 8K x 14 organization, 368-byte RAM, 33 I/O pins, three timers, two capture/compare/PWM modules, an 8-channel 8-bit ADC, and an instruction cycle of 200 ns at 4 MHz. Built around a RISC Harvard architecture with separate program and data buses, the device executes one instruction per cycle. Operating voltage spans 4.0 V to 6.0 V, and the commercial temperature grade is 0 C to +70 C, making it suitable for office and consumer-industrial environments. Typical applications include industrial control loops using the on-chip ADC, sensor interfacing via SPI or I2C peripherals, motor and lighting control through the two CCP PWM channels, and serial communication bridges using the USART. The combination of analog, digital, and serial peripherals allows designers to implement compact single-chip solutions for measurement and actuation. When designing with this part, confirm whether OTP (one-time-programmable) is acceptable or whether a Flash-based equivalent such as PIC16F77 is preferred for field reprogrammability. Verify the PLCC-44 socket footprint and decoupling strategy, since this CMOS MCU is sensitive to supply ripple near ADC input channels.

PIC16C77-04/PQ

PIC16C77-04/PQ - 8-bit CMOS MCU 14KB EPROM 368 RAM | Microchip

The Microchip Technology PIC16C77-04/PQ is an 8-bit CMOS RISC microcontroller with integrated 8-channel 8-bit analog-to-digital converter, 14 KB EPROM program memory, 368 bytes RAM, and 33 I/O pins, offered in a 44-pin MQFP (PQ) package. It executes instructions in a 200 ns cycle at 20 MHz and operates from 4 V to 5.5 V across commercial, industrial, and extended temperature ranges. The 35-instruction RISC core is fully static and binary-compatible with the PIC16C5X and PIC12CXXX families. What is a PIC16C7X microcontroller? The PIC16C7X family is a mid-range 8-bit RISC microcontroller line from Microchip, sitting between the baseline PIC16C5X and the high-performance PIC18 families. These MCUs integrate on-chip EPROM, RAM, an ADC, and a variety of timers and serial peripherals into a single CMOS device, enabling compact embedded designs without external program memory. They are widely used as drop-in upgrade paths from PIC16C5X designs that require A/D conversion and interrupt-driven peripherals. Key features include 14 KB EPROM program memory, 368 bytes RAM, 22 I/O lines capable of 25 mA source/sink drive, eight 8-bit A/D channels, three timers, USART, and a watchdog timer. The -04 speed grade denotes a 4 MHz oscillator input / 20 MHz instruction execution, while the /PQ suffix indicates the windowed CERDIP-style 44-pin plastic MQFP package, an older through-hole-style plastic-quad flat-pack form factor used in legacy industrial designs. Architecturally, the PIC16C77-04/PQ uses Harvard-architecture separate program and data buses, allowing simultaneous instruction fetch and operand access. The RISC CPU implements 35 fixed-format instructions, all single-cycle except for program branches, which take two cycles. This compact instruction set, combined with 8 hardware stack levels and interrupt-driven peripherals, makes the PIC16C77-04/PQ suitable for deterministic real-time control loops. Typical applications include industrial motor control, instrumentation with analog sensor input, legacy embedded control boards, automotive subsystems, and white-goods control where integrated ADC and EPROM-based field programmability are valued. The wide operating voltage range and strong I/O drive capability also support driving discrete transistors and small relays. When designing with the PIC16C77-04/PQ, pay attention to the EPROM windowed package variant if in-circuit reprogrammability is required, and ensure the watchdog timer is properly handled in software to recover from lockups. The Microchip recommendation for new designs is the flash-based PIC16F77, which provides identical peripherals in a pin-compatible footprint with field-upgradeable program memory.
