PIC12CE674-04/P - 8-Bit 4MHz OTP MCU, 3.5KB | Microchip

The Microchip Technology PIC12CE674-04/P is an 8-bit CMOS OTP-based PIC microcontroller featuring the PIC12 mid-range core, 3.5KB (2K x 14) of One-Time-Programmable program memory, 128 bytes of RAM, and 16 bytes of EEPROM data memory, packaged in an 8-pin PDIP through-hole enclosure. It executes instructions at a 400 ns cycle time from a 4 MHz internal clock and integrates a 4-channel 8-bit analog-to-digital converter alongside five general-purpose I/O pins. A microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (ROM/Flash/OTP), data memory (RAM), peripherals, and I/O on one die; the PIC12C/CE67x family specifically belongs to Microchip's 8-bit PIC RISC architecture hierarchy (PIC10/12/16/18 -> 8-bit PIC -> PIC microcontroller -> embedded computing). This part is a member of the low-pin-count, low-cost OTP MCU category targeting high-volume cost-sensitive embedded designs that do not require in-system reprogrammability. Key features include a 35-instruction RISC instruction set with single-cycle execution (400 ns at 4 MHz) for deterministic throughput, an integrated 8-bit ADC with four input channels, 16 bytes of EEPROM for non-volatile parameter storage across power cycles, an internal 4 MHz RC oscillator eliminating external clock components, and a wide 2.5 V to 5.5 V supply range supporting both 3.3 V and 5 V system rails. Watchdog timer, power-on reset, and brown-out detection enhance field reliability. The PIC12CE674 utilizes the enhanced mid-range 14-bit instruction word architecture with a 33 to 35 instruction set, an 8-level hardware stack, and direct/indirect addressing modes. The OTP program memory is one-time programmable, making the part well suited for mature firmware in mass-production runs where code stability is established. The device's CMOS static design allows clock speeds down to DC for ultra-low-power sleep states. Typical applications include low-cost consumer appliance controls, sensor signal conditioning front-ends, simple LED lighting controllers, battery-powered handheld instruments, and replacement of discrete logic in space-constrained designs. The small 8-pin footprint and integrated ADC suit applications that need basic intelligence without a large pin count or DSP horsepower. A key design consideration: because this is an OTP device, firmware must be fully validated on a windowed or Flash equivalent (e.g., PIC12F675) before committing to the PIC12CE674 for production. The 5 I/O pins must be carefully allocated between ADC inputs, digital I/O, and the MCLR/reset function.

PIC12CE674-04E/P

PIC12CE674-04E/P - 8-Bit 4MHz OTP MCU 3.5KB Flash | Microchip

The Microchip Technology PIC12CE674-04E/P is an 8-bit CMOS OTP (One-Time Programmable) RISC microcontroller built on the PIC12C family core, integrating 3.5KB (2K x 14 words) of program memory, 128 bytes of SRAM, and 16 bytes of non-volatile EEPROM data memory in an 8-pin PDIP through-hole package. It operates from a 4 MHz internal clock (the "-04" speed grade) and executes instructions in a single 400 ns cycle (excluding program branches which take two cycles), giving 5 MIPS peak throughput from its 35 single-word instruction RISC set. The extended "CE" variant adds an integrated 4-channel 8-bit Analog-to-Digital Converter plus an on-chip serial EEPROM interface. A PIC microcontroller (Programmable Intelligent Computer, or Peripheral Interface Controller) is a class of 8/16/32-bit RISC microcontrollers built on a Harvard architecture - separate program and data buses - that became the de-facto standard for low-pin-count embedded control. The PIC12 family sits at the entry level of Microchip's PIC line (PIC10/12/16/18 hierarchy, scaling up to PIC24/dsPIC and PIC32), prioritizing small package count, low cost, and deterministic interrupt response over raw compute. Within the PIC12 family, the "CE" sub-family specifically adds EEPROM data memory on-chip for parameter storage in user-reprogrammable applications. Key features of this part include: 6 general-purpose I/O pins multiplexed with ADC inputs and the MCLR/reset function, an 8-bit timer/counter (TMR0) with an 8-bit prescaler, a watchdog timer with its own on-chip RC oscillator for reliable resets, an internal 4 MHz RC oscillator (plus an optional external oscillator), and in-circuit serial programming (ICSP) capability via two pins. The four ADC channels share the I/O pins and offer 8-bit resolution. Architecturally, the device uses a 14-bit instruction word and an 8-bit data path with a two-stage pipeline, allowing most instructions to complete in one oscillator cycle. The OTP program memory is one-time programmable but supports field updates via ICSP for prototypes and small production runs. Power management features include a power-on reset, brown-out detection, and a SLEEP mode that drops current to sub-microamp levels. Typical applications include low-cost sensor interfaces, appliance controls, LED lighting controllers, automotive body electronics (under-the-hood sensors), battery chargers, and replacement of discrete logic in 8-pin designs. The integrated ADC and EEPROM make it especially well suited to small-signal analog acquisition with non-volatile calibration storage. When designing with this MCU, the "E" suffix denotes the extended (-40C to +125C) industrial operating temperature range, which is essential for automotive and outdoor deployments. The OTP program memory requires in-system programming via ICSP - code cannot be erased and rewritten like Flash - so provision a programming header and pre-test all firmware on a Flash-equivalent development device before committing code to OTP production units.

PIC12CE674-10/P - 8-Bit 10MHz OTP MCU w/ 3.5KB | Microchip

The Microchip Technology PIC12CE674-10/P is an 8-bit CMOS OTP-based microcontroller that delivers 400 ns instruction execution in a compact 8-pin PDIP package. It features a 10 MHz maximum clock, 3.5 KB (2K x 14) of One-Time-Programmable program memory, 128 bytes of RAM, and 16 bytes of EEPROM data memory. The integrated 4-channel 8-bit Analog-to-Digital converter and onboard EEPROM distinguish it from the sibling PIC12C672, which lacks EEPROM. This part number carries the "/P" suffix denoting the through-hole 8-pin PDIP package. An OTP microcontroller (One-Time-Programmable) is a category of non-volatile microcontrollers where the program memory can be written exactly once after manufacture, using a programmer device. The PIC12CE674 belongs to the PIC12 family of microcontrollers, which sits within the broader PIC mid-range x14 architecture, and ultimately within the microcontroller (MCU) -> embedded controller -> semiconductor device taxonomy. OTP MCUs are favored for low-cost, high-volume products where firmware is finalized before production and field re-programmability is not required. Key features include 35 single-word instructions, an internal 4 MHz RC oscillator (the "-10" speed grade also supports 10 MHz external clock), 6 I/O pins, a wide 3.0 V to 5.5 V operating voltage range, and a watchdog timer with its own on-chip RC oscillator. The PIC architecture's RISC-like instruction set allows most instructions to execute in a single instruction cycle, giving effective throughput of roughly 5 MIPS at 10 MHz. The 8-pin PDIP form factor is fully compatible with through-hole hobbyist, prototyping, and legacy industrial designs. This device integrates CMOS Flash/OTP technology with Microchip's mid-range 14-bit instruction word, providing deterministic interrupt latency, hardware stack, and direct LED-driving capability on GPIO pins. The 4-channel 8-bit ADC handles simple sensor reads, while the 16-byte EEPROM offers small non-volatile parameter storage (e.g., calibration or configuration) without external memory ICs. Internal oscillator options further reduce BOM cost by eliminating external crystals in many designs. Typical applications include low-cost consumer appliances, sensor signal conditioning front-ends, simple LED controllers, automotive body electronics modules, battery chargers, and replacement of discrete logic in cost-sensitive designs. The wide 3.0 V to 5.5 V supply range allows direct connection to 3.3 V or 5 V rails, and the -40 °C to +85 °C commercial operating range covers most non-automotive environments. When designing with this device, evaluate whether OTP or Flash-based memory fits your lifecycle. For prototyping and field updates, the PIC12F683 (Flash) is a closer functional drop-in within the same 8-pin footprint. For volume production where firmware is locked, PIC12CE674-10/P remains a cost-optimized choice.

An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and configurable peripheral I/O on one die. Within the broader taxonomy, 8-bit MCUs sit under microcontroller -> embedded processor -> semiconductor. The PIC12CExxx family occupies the smallest-footprint 8-bit niche: 8-pin packages with built-in ADC and, in the 'CE' variants, on-chip EEPROM data memory. Key features of the PIC12CE674 include 5 I/O pins (GP0-GP5 shared with MCLR on GP5), 35 single-word instructions executed in 400 ns (10 MHz), internal 4 MHz RC oscillator option, watchdog timer with on-chip RC oscillator, programmable code protection, and an industrial/automotive operating temperature grade (the '-10E' suffix indicates the 10 MHz speed grade with extended temperature range). It is pin-compatible with the smaller PIC12C672/673 family members, allowing code to scale up when more memory is required. Architecturally, the PIC12CE674 uses a Harvard RISC core with separate program and data buses, a 14-bit instruction word, and a single hardware accumulator (working register). The integrated 16-byte EEPROM is accessed through a register-mapped SFR interface and supports up to 1 million erase/write cycles per Microchip documentation, making it suitable for user-configurable settings stored across power cycles. Typical applications include low-cost sensor signal conditioners, single-channel data loggers, automotive body controllers and appliance front panels, low-end LED drivers with PWM, smart-battery chargers, and replacement of discrete logic gates on legacy boards. The wide operating range also makes it a candidate for industrial white goods and consumer remote-control devices. When designing with the PIC12CE674, note that the 8-pin PDIP is the most PCB-friendly variant for hand-soldered prototypes; the SOIC-8 (-SN) or DFN (-MF) surface-mount packages are preferred for high-volume production. The internal RC oscillator reduces BOM cost but trades frequency accuracy (typically +/-1-2%) against the precision of an external crystal.

PIC12CE674-10I/P

PIC12CE674-10I/P - 8-Pin 8-Bit CMOS MCU with ADC & EEPROM

The Microchip Technology PIC12CE674-10I/P is an 8-bit CMOS OTP microcontroller housed in an 8-pin PDIP (DIP-8) through-hole package, integrating 3.5KB (2K x 14) of OTP program memory, 128 bytes of RAM, 16 bytes of EEPROM data memory, and a 4-channel 8-bit A/D converter. It is a member of the PIC12C67x family, operates from 3.0V to 5.5V, and runs at a maximum clock frequency of 10 MHz (4 MHz internal oscillator). The "-10" speed suffix denotes the 10 MHz maximum oscillator frequency, while the "I" indicates the industrial -40C to +85C temperature grade. An 8-bit microcontroller (MCU) is a microprocessor-integrated circuit that combines a CPU, memory (ROM/RAM), and peripherals on a single die. The PIC12CE674 falls within the hierarchy: 8-bit microcontroller -> RISC microcontroller -> embedded controller -> semiconductor. Its 35 single-word instruction RISC architecture delivers deterministic 400 ns instruction execution, while the integrated EEPROM provides non-volatile data storage for calibration, configuration, or user-set parameters. Key features of the PIC12CE674 include four 8-bit ADC channels, four I/O pins with individual direction control, an internal 4 MHz RC oscillator (selectable with external oscillator), an MCLR reset input, and a watchdog timer with its own on-chip RC oscillator for reliable operation. The device draws very low operating current, with typical values in the low milliamp range at 5V and microamp sleep currents. The PIC12CE674 uses Harvard architecture with separate program and data buses, allowing simultaneous instruction fetch and operand access. Its 14-bit instruction word enables compact code density, and the 8-level deep hardware stack simplifies interrupt handling and subroutine calls. The integrated A/D converter uses successive approximation with analog input multiplexing across GP0-GP3 pins. Typical applications include battery chargers, sensor signal conditioning, smart cards, security systems, and small appliance controllers where pin count, cost, and integrated EEPROM and ADC are critical. In automotive body electronics, industrial process control, and consumer devices, the PIC12CE674 provides a compact 8-pin solution with non-volatile parameter storage. When designing with the PIC12CE674, ensure the oscillator configuration matches the application; the internal 4 MHz RC simplifies designs but allows less precision than a crystal. For EEPROM write endurance of 1M cycles typical, implement wear-leveling if frequent parameter updates are required.

PIC12CE674/JW

PIC12CE674/JW - 8-Bit 10MHz MCU, 3.5KB EPROM/UV, 8-CDIP Window | Microchip

The Microchip Technology PIC12CE674/JW is an 8-bit CMOS RISC microcontroller in the PIC® 12C family, packaged in an 8-pin CERDIP (CDIP) windowed package that allows UV erasure of the on-chip program memory. It integrates 3.5 KB (2K × 14) of One-Time-Programmable EPROM, 128 bytes of SRAM, 16 bytes of EEPROM data memory, and a 4-channel 8-bit A/D converter. The device executes instructions in 400 ns at 10 MHz and contains only 35 single-word instructions, making it simple to program in assembly or C. A microcontroller (MCU) is a single-chip computer that combines a CPU core, program memory, data memory, and peripherals on one die. Within that taxonomy, the PIC12CE674/JW sits in the 8-bit OTP/EPROM microcontroller category, between the simpler PIC10 and PIC12C508/509 base families and the more capable PIC16 mid-range line. It is designed for low-cost, low-pin-count control tasks where a small amount of self-modifying data memory (EEPROM) and analog sensing (A/D) are required without scaling up to a 14- or 20-pin device. Key features include 5 general-purpose digital I/O pins, 4 multiplexed 8-bit ADC channels with 8-bit resolution, internal 4 MHz RC oscillator option, an external oscillator pin pair, power-on reset, watchdog timer with its own on-chip RC oscillator, and code-protection circuitry. The CDIP/JW (windowed) package is intended for engineering development and prototype validation because the quartz window permits UV erasure and re-programming of the EPROM, while non-windowed plastic DIP and SOIC variants are used for production. Architecturally the part is built on a 14-bit instruction-word Harvard RISC core, allowing most instructions to complete in one instruction cycle (4 clock periods) and yielding predictable real-time behavior. The 8-bit accumulator-based ALU, 8-level hardware stack, and direct/indirect addressing modes provide a flat programming environment, while the integrated 16-byte EEPROM offers non-volatile storage for user data such as calibration constants or serial numbers without external memory. Typical applications include appliance control, sensor signal conditioning with on-chip ADC, simple closed-loop fan or motor speed control, security and access peripherals, and battery chargers. Designers also use it as a glue logic replacement for discrete 74-series TTL in legacy industrial controllers where 5 V tolerance and EPROM-based firmware are still favored. When designing with this part, note the 0°C to +70°C commercial temperature grade, the 3.0 V to 5.5 V operating range, and that the JW windowed package costs more than the OTP-only /P or /SM production parts. Always program using a Microchip MPLAB-supported device programmer and ensure the EPROM is fully UV-erased before re-programming to avoid bit-stuck errors.

The Microchip Technology PIC12F1501-I/MF is an 8-bit Flash microcontroller based on the enhanced mid-range core with 49 instructions and 16 stack levels, housed in an 8-pin DFN (3x3 mm) package. It integrates 1.75KB (1K x 14) of Flash program memory, 64 bytes of RAM, a 10-bit ADC, and runs at up to 20MHz instruction rate from a 2.5V to 5.5V supply. An 8-bit microcontroller (MCU) is a small computing device that integrates a CPU, non-volatile program memory (typically Flash), working RAM, and a set of peripheral interfaces into a single low-cost silicon die. The 8-bit PIC architecture sits within a broader taxonomy: MCU -> microcontroller -> embedded processor -> semiconductor. PIC12F-series parts specifically target low-pin-count, cost-sensitive designs where every GPIO and instruction cycle is precious. Key differentiating features of the PIC12F1501 include its on-chip 10-bit ADC with up to 6 analog input channels, hardware PWM/Capture/Compare modules, an internal configurable oscillator that eliminates external crystals in many designs, and the DFN-8 package with 6 general-purpose I/O pins plus dedicated reset and oscillator functions. The instruction set provides hardware atomic bit operations, simplifying firmware for I/O-heavy tasks like driving LEDs, reading sensors, or pulsing MOSFET gates. The device operates from -40C to +85C industrial temperature, supports in-circuit serial programming (ICSP) via PICkit 3, MPLAB ICD 3, and the Curiosity development board, and uses enhanced low-power sleep modes suitable for battery-powered sensor nodes. Its 49-instruction enhanced mid-range core delivers approximately 5 MIPS at 20MHz. Typical applications include LED lighting control, simple sensor hubs, battery chargers, remote controls, and auxiliary MCU companion chips where minimal pin count and low BOM cost matter more than raw throughput. The internal oscillator and DFN-8 footprint also suit space-constrained wearables. Designers should evaluate whether 1.75KB of Flash and 64 bytes of RAM are sufficient for their application code size, and plan for the ICSP header footprint if in-circuit debugging is required. PICkit 3 or ICD 3 plus header AC244051/AC244052 is needed for external debug on this pin-limited package.

PIC12F1571-I/MF - 8-Bit MCU, 32MHz, 1.75KB Flash, 8-DFN | Microchip

The Microchip Technology PIC12F1571-I/MF is an 8-bit PIC microcontroller in an 8-pin DFN (3x3 mm) package, delivering 32 MHz CPU performance with 1.75 KB (1K x 14) Flash program memory. It integrates three independent 16-bit PWMs, a comparator, 128 bytes of RAM, and configurable peripherals aimed at precision analog and motion-control tasks. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash/ROM), volatile working memory (RAM), and peripherals such as timers, ADCs, communication interfaces, and PWMs. The PIC12F1571 belongs to the 8-bit PIC12 family from Microchip, sitting within the broader category of embedded microcontrollers -> microcontrollers -> integrated circuits. This hierarchy places it alongside PIC16, PIC18, PIC24, and dsPIC devices as part of Microchip's PIC architecture. Key differentiating features include three 16-bit PWMs with independent timers (versus typical 10-bit PWMs in this class), a 32 MHz internal oscillator supporting 16 MHz operation down to 2.3 V, an on-chip 8-bit DAC reference, and a configurable logic cell that lets designers route peripheral functions to pins without firmware changes. The device operates across 2.3 V to 5.5 V and offers 6 I/O pins plus 1 input-only pin, packaged in a space-saving 8-lead DFN footprint. The PIC12F1571 uses Microchip's enhanced mid-range core (49 instruction set, 16-level hardware stack), enabling deterministic interrupt response within one instruction cycle. Its 16-bit PWM resolution is critical for applications such as LED dimming, full-color RGB lighting, and switch-mode power supply control, where 10-bit PWM produces visible color steps or audible ripple artefacts. The on-chip 5-bit DAC and reference module simplify analog set-point generation. Typical applications include RGB LED color mixing, high-resolution stepper motor control, fan speed control via closed-loop PWM, digital power supply compensation, and battery-powered sensor nodes. In each case the 16-bit PWM resolution directly improves control smoothness and reduces external component count. When designing with this MCU, derate CPU clock when VDD falls below 3.0 V (per the datasheet). Always use proper decoupling - 100 nF ceramic close to VDD plus 10 uF bulk - and place the exposed pad of the DFN package on a contiguous ground copper pour for thermal dissipation and low-impedance return.

The device operates at up to 32 MHz internal clock, delivers 1.75 KB (1K x 14) of self-programmable Flash program memory, 128 bytes of RAM, and integrates a 10-bit ADC, two comparators, a 5-bit DAC and an 8-bit timer plus the three 16-bit PWM channels. The -I temperature grade spans -40C to +85C, suitable for industrial and consumer environments. The 8-MSOP (MS) package keeps the device footprint below 15 mm^2, making it well suited to space-constrained designs. A PIC microcontroller is a compact, Harvard-architecture single-chip computer that integrates a CPU, non-volatile Flash memory, RAM, and a configurable set of peripherals such as timers, ADC, PWM and communication modules. Within the broader taxonomy, PIC12F1571 sits at microcontroller -> 8-bit MCU -> PIC12 family -> PIC12F157X sub-family -> semiconductor. PIC microcontrollers are widely used as state-machine controllers and glue-logic replacements where deterministic response and ultra-low standby power matter more than raw compute throughput. Key features include three independent 16-bit PWMs with independent timers (ideal for high-resolution LED lighting and stepper motor control), 128 bytes of RAM, a 32 MHz internal oscillator, an on-chip 10-bit ADC, two rail-to-rail comparators with selectable hysteresis, a 5-bit DAC reference, and a PWM shutdown/sync logic block. The device supports 100,000 Flash write/erase cycles and >40-year data retention per Microchip. Architecturally, the PIC12F1571 uses Microchip's enhanced mid-range 14-bit instruction set with a single-cycle hardware multiplier and a deep interrupt hardware stack. The PWM block provides edge-aligned, center-aligned and variable-phase operation, allowing multi-channel lighting or motor phases to be generated without software overhead. Intelligent Analog integration lets the comparators trigger PWM shutdown for overcurrent protection. Typical applications include LED lighting control, stepper motor and BLDC commutation, small SMPS and digital power conversion, general-purpose timers and sensor hubs, and battery-charging front ends. The PIC12F1571-I/MS is pin-compatible with the PIC12F1501 and PIC12LF1559 families, simplifying migration. When designing, budget for at least 2.0V supply operation on F variants and 1.8V on LF variants; an external decoupling capacitor of 100 nF on VDD is recommended within 4 mm of the pin.

PIC12F1571-I/P

PIC12F1571-I/P - 8-bit MCU, 32MHz, 1.75KB Flash, 8-PDIP | Microchip

The Microchip Technology PIC12F1571-I/P is an 8-bit PIC12 RISC microcontroller IC with 32MHz CPU speed, 1.75KB (1K x 14) Flash program memory, 128 bytes SRAM, and three independent 16-bit PWMs, housed in an 8-pin PDIP through-hole package. It integrates a 10-bit ADC, a 5-bit DAC, a comparator, and the eXtreme Low-Power (XLP) feature set. An 8-bit microcontroller is a single-chip computer that integrates a CPU, RAM, non-volatile program memory (Flash), and I/O peripherals. PIC microcontrollers use a Harvard RISC architecture with separate program and data buses, executing one instruction per clock cycle (excluding branches) - which is why the PIC12F1571-I/P achieves 32 MIPS at 32MHz CPU clock. Microcontroller ICs sit at the hierarchy of: MCU -> 8-bit MCU -> PIC12 family -> PIC12F157x sub-family. The 8-pin PDIP form factor is part of the DIP (Dual In-line Package) family of through-hole surface-mount predecessors, ideal for breadboarding and hobbyist prototyping. Key features include three independent 16-bit Pulse-Width Modulation (PWM) channels with fine resolution for LED dimming, motor control, and switch-mode power supply (SMPS) feedback; a 10-bit Analog-to-Digital Converter (ADC) with up to 4 channels; a 5-bit Digital-to-Analog Converter (DAC); a comparator with selectable reference; on-chip 32MHz internal oscillator; and 128-byte data SRAM. The XLP feature provides nanoWatt sleep currents below 20 nA typical in sleep mode, enabling battery-powered applications that last years on a single coin cell. The PIC12F1571-I/P uses Microchip's enhanced mid-range 14-bit instruction set, which supports interrupts with hardware context saving, an 8-deep hardware stack, and direct/indirect/relative addressing modes. The device is programmed and debugged through In-Circuit Serial Programming (ICSP) via two pins (ICSPCLK/ICSPDAT), requiring no separate programmer port. The integrated 32MHz internal oscillator with ±2% accuracy over voltage and temperature eliminates the need for an external crystal in most designs. Typical applications include high-resolution LED lighting and color mixing, stepper motor and DC motor speed control via the 16-bit PWMs, small switch-mode power supplies, battery chargers, remote controls, IoT sensor nodes, and any space-constrained low-cost 8-pin embedded design. The combination of three 16-bit PWMs and a 5-bit DAC makes it particularly well-suited for generating complex analog waveforms or driving RGBW LEDs with fine intensity control. When designing with this device, note that only 6 of the 8 pins are usable as general-purpose I/O because two pins are dedicated to ICSP. For production programming in-circuit, allow for the ICSP header. The device supports 2.3V to 5.5V operation, so a single 3.3V or 5V rail is sufficient.
