PIC12CE519-04I/SM - 8-Bit 4MHz 1.5KB OTP MCU SOIJ-8 | Microchip

The Microchip Technology PIC12CE519-04I/SM is an 8-bit, 4 MHz CMOS one-time programmable (OTP) microcontroller from the PIC12C5xx family, packaged in an 8-pin SOIJ (SM) with 1.5 KB of program memory (1K x 12), 41 bytes of RAM, and 6 I/O pins. The device integrates an internal 6-bit (or selectable 4-bit) digital-to-analog converter and on-chip EEPROM data memory, differentiating it from the simpler PIC12C508/509 cousins while retaining the same RISC-style 12-bit instruction core. An 8-bit microcontroller (MCU) is a small computing-on-a-chip that integrates a CPU, non‑volatile program memory, working RAM, and peripheral I/O into a single die; in the broader taxonomy it sits under microcontroller -> embedded controller -> integrated circuit -> semiconductor. The PIC12C5xx family occupies the entry-level tier of Microchip's 8-bit line, optimized for low-cost, low-pin-count applications that still need deterministic execution and a tiny footprint. Key features include 4 MHz maximum operating frequency (200 ns instruction cycle), 33 single-word instructions, 8-bit wide data path, two 8-bit timers, a watchdog timer with on-chip RC oscillator, and a power-on-reset circuit. The device draws roughly 1.8 mA at 5 V / 4 MHz and supports operation from 2.5 V to 5.5 V across the industrial -40 °C to +85 °C temperature range. Architecturally, the PIC12CE519 uses a Harvard RISC core with separate program and data buses, a 14-bit wide instruction word, and a two-stage pipeline that delivers most instructions in a single cycle. The integrated DAC and serial EEPROM emulation logic allow direct analog output without external components, which simplifies bill-of-material cost. Typical applications include appliance control, security sensors, small consumer products, low-end remote controls, and battery-powered accessories where the on-chip DAC and EEPROM are used to trim or store calibration data. Industrial control front-ends that need deterministic timing and minimum component count are also well served by this part. A key design consideration is OTP program memory: code cannot be updated in-circuit, so firmware must be fully validated before programming. Developers should use the JW windowed variant (PIC12CE518/JW or PIC12CE519/JW) for prototyping and migrate to the OTP part once firmware is frozen. This page synthesizes distributor pricing, drop-in same-family and cross-family alternatives, application references, and practical design notes not consolidated in the manufacturer datasheet.

PIC12CE519-04I/SN - 8-Bit OTP MCU, 1.5KB, 4MHz | Microchip
PIC12CE519-04I/SN

PIC12CE519-04I/SN - 8-Bit OTP MCU, 1.5KB, 4MHz | Microchip

The Microchip Technology PIC12CE519-04I/SN is an 8-bit, RISC-architecture, one-time programmable (OTP) CMOS microcontroller from the PIC12C5xx family, packaged in an 8-pin SOIC (SN) outline with industrial -40C to +85C temperature rating. It integrates a 1.5 KB (1K x 12) OTP program memory, 41 bytes of data RAM, 16 bytes of EEPROM data memory, and 6 general-purpose I/O pins capable of 25 mA source/sink per pin for direct LED or relay drive. The CPU executes one instruction per 200 ns cycle, yielding a 4 MHz instruction throughput from a 4 MHz oscillator input. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and programmable I/O peripherals. The PIC12CE519 sits at the entry-level of the 8-bit MCU hierarchy - below Flash-based PIC12F and PIC16 families - and is intended for high-volume cost-sensitive applications where one-time programmable code is acceptable. Within the power-management hierarchy it is essentially the controller that drives timing, sequencing, and discrete logic functions on a board. Key features include four selectable oscillator options (including an internal 4 MHz RC oscillator with programmable calibration, eliminating the external crystal in many designs), a Watchdog Timer with its own on-chip RC oscillator for reliable operation, Power-On Reset (POR), Device Reset Timer (DRT), code protection, and 1,000,000 erase/write cycle EEPROM endurance on the data side. The Harvard RISC core offers 33 single-word instructions, deterministic interrupt latency, and an 8-bit real-time counter (TMR0) with 8-bit programmable prescaler. Typical applications span simple appliance timers, button-driven LED controllers, single-sensor data loggers, relay sequencers, push-button debouncing, and small-appliance logic replacement of discrete glue logic. The combination of 6 high-current I/Os, on-chip EEPROM for user data, and 35 single-word instructions makes the PIC12CE519 efficient in space-constrained 8-pin designs. When designing with the PIC12CE519, choose between the internal 4 MHz RC oscillator and an external crystal based on timing accuracy requirements - the internal RC drifts more with voltage and temperature but saves two pins and an external resonator. In-system programming is via Microchip's ICSP protocol through the GP0/GP1 pins, so these must remain accessible in the PCB layout. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the standalone Microchip datasheet - giving engineers a single authoritative reference for sourcing, designing in, and replacing the PIC12CE519-04I/SN.

PIC12CE519/JW

PIC12CE519/JW - 8-Bit 4MHz 1.5KB EPROM MCU, 8-CDIP Windowed | Microchip

The Microchip Technology PIC12CE519/JW is an 8-bit CMOS RISC microcontroller in the PIC 12C family, packaged in an 8-pin ceramic windowed CDIP (0.300", 7.62mm) designed for through-hole mounting and UV-erasable development. It runs at up to 4MHz, integrates 1.5KB EPROM program memory (1K x 12 words), 41 bytes of RAM, and 16 bytes of EEPROM data memory, providing a compact and inexpensive platform for embedded control. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, RAM, non-volatile program memory, and peripherals on a single die. MCUs sit beneath microprocessors in the computing hierarchy, prioritizing low power, deterministic real-time I/O, and small footprint over raw throughput. The PIC 12C family targets cost-sensitive 6- and 8-pin applications where a tiny RISC core, a minimal instruction set (33 single-word instructions for the PIC12CE519), and very low standby current are more important than memory depth or compute performance. Key features of the PIC12CE519/JW include 4MHz maximum operating frequency, 2.0V-5.5V (or 3.0V-5.5V per the verified data) supply range, six general-purpose I/O pins multiplexed with peripherals, an 8-bit timer/counter, a watchdog timer, an analog comparator, and a programmable weak pull-up on GP0/GP1/GP3. The device also provides an on-chip 4MHz RC oscillator and supports external clock, RC, and XT oscillator modes for application flexibility. Power-managed Sleep mode with multiple wake-up sources reduces quiescent current to microampere levels. The PIC12CE519/JW uses Microchip's Enhanced PIC16C5X core architecture with a 12-bit instruction word, 2-level hardware stack, and direct/indirect addressing modes. The ceramic windowed CDIP package exposes the silicon die for UV erasure, allowing the same physical device to be reprogrammed many times - a feature reserved for development, prototyping, and low-volume engineering builds. Production deployments typically use the one-time-programmable JW or the OTP plastic DIP/SOIC variants for cost reasons. Typical applications include low-cost consumer appliances, sensor interface front-ends, battery-powered remote controls, toys, simple timers, and educational development kits. The integrated EEPROM data memory is useful for storing calibration constants, configuration values, or serial numbers without external non-volatile chips. The 6 GPIO pins are sufficient for driving relays (via transistors), reading switches, or talking to a single UART-style bit-banged peripheral. When designing with this part, note that the JW windowed CDIP variant is functionally identical to the OTP/EPROM PIC12CE519 die - the difference is only the package and erase mechanism. Plan your BOM by reserving JW units for engineering builds and switching to the plastic-DIP PIC12CE519-04/P or SOIC PIC12CE519-04/SM for production to reduce cost. Also confirm the supply voltage range carefully; some PIC12CE519 speed grades (e.g., -04 and -10) differ in minimum Vdd and maximum oscillator frequency.

PIC12CE519T-04/SN - 8-bit OTP MCU, 1.5KB EPROM, 41B RAM | Microchip
PIC12CE519T-04/SN

PIC12CE519T-04/SN - 8-bit OTP MCU, 1.5KB EPROM, 41B RAM | Microchip

The Microchip PIC12CE519T-04/SN is an 8-bit CMOS RISC microcontroller with 1.5 KB of One-Time Programmable (OTP) EPROM program memory, 41 bytes of RAM data memory, and an integrated 16-byte EEPROM data space, housed in an 8-pin SOIC (SN) package. The 'T' suffix denotes tape-and-reel packaging and the '-04' suffix specifies a 4 MHz maximum clock input, yielding a 1 microsecond instruction cycle. Six general-purpose digital I/O pins, a watchdog timer, an internal 4 MHz RC oscillator, and an on-chip EEPROM make it suited to compact, cost-sensitive embedded designs. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data memory, and peripherals. The PIC12CE519 belongs to Microchip's PIC12C 8-bit baseline family and sits inside the broader taxonomy: 8-bit MCU -> RISC microcontroller -> PIC microcontroller -> embedded processor -> semiconductor. In a typical system hierarchy it operates below a host processor or human-machine interface, handling housekeeping tasks such as sensor sampling, switch debouncing, LED blinking, simple PWM generation, and serial bit-banged communication. Key features include 33 single-word instructions (most are single-cycle at 1 microsecond, branches take two cycles), a 4 MHz external clock input, an on-chip EEPROM for non-volatile data storage, a power-on reset (POR) and brown-out reset, a programmable watchdog timer (WDT) with its own on-chip RC oscillator, and wide operating voltage from 2.5V to 5.5V. These features give designers a tiny, low-pin-count MCU capable of replacing discrete logic in space-constrained products. The integrated EEPROM is the defining difference versus the sibling PIC12C519 - it lets the firmware store calibration values, configuration settings, or usage counters that must survive power cycles. Technically, the device uses a Harvard RISC architecture with separate program and data buses, enabling single-cycle instruction fetch and execution. A two-stage pipeline overlaps fetch and execute, and the 8-bit ALU plus 14-bit instruction word is optimized for compact code density. Peripheral integration is deliberately minimal - GPIO, timer0, watchdog, and EEPROM - to keep die size, cost, and current consumption low. Typical active current is well below 1 mA at 4 MHz, making the part appropriate for battery-powered and always-on auxiliary controllers. Typical applications include appliance control sub-modules (rice cookers, fans, coffee makers), remote control transmitters, sensor interface front-ends, smart LED controllers, battery chargers, automotive interior accessories such as ambient lighting or window controls, and industrial timer or counter modules. The wide 2.5V to 5.5V range supports both 3.3V and 5V rails. The on-chip EEPROM is especially useful for storing user-setpoints, calibration coefficients, or device serial numbers without external memory. A key design consideration is OTP-only program memory: the PIC12CE519T-04/SN cannot be re-programmed in-circuit, so firmware must be validated before device programming and one-time-only programming strategy must be planned. The 41-byte RAM is small - allocate stack and scratchpad carefully, avoid large local buffers, and consider migrating to a flash-based PIC10F or PIC12F part for prototyping before committing to OTP. For development, use the PIC12CE519 with a JW windowed package or a flash-based sibling such as PIC12F519 to iterate firmware quickly.

PIC12CE519T-04I/SM

PIC12CE519T-04I/SM - 8-bit MCU, 1.5KB OTP, 4MHz, 8-SOIJ | Microchip

The Microchip Technology PIC12CE519T-04I/SM is an 8-bit CMOS one-time-programmable (OTP) microcontroller from the PIC12C5xx family, featuring 1.5KB of program memory (1K x 12), 41 bytes of RAM, 6 I/O pins, and a 4MHz internal oscillator, housed in an 8-pin SOIJ (SM) surface-mount package with industrial temperature range (-40C to +85C). The "T" suffix denotes tape-and-reel packaging, "04" indicates the 4MHz maximum oscillator frequency, "I" marks the industrial temperature grade, and "SM" designates the 8-SOIJ package. A PIC microcontroller (MCU) is a compact, low-power programmable processor built around a RISC (Reduced Instruction Set Computer) architecture. PIC MCUs sit within the broader hierarchy of microcontrollers -> embedded processors -> semiconductors, and the PIC12C5xx series specifically targets space-constrained, cost-sensitive applications where minimal external components and low pin count are critical. Unlike flash-based MCUs, OTP devices are programmed once and cannot be erased, making them ideal for high-volume, fixed-function products. Key features include a 200ns instruction execution time, an 8-bit real-time clock/counter (TMR0) with programmable prescaler, power-on reset (POR), device reset timer (DRT), watchdog timer (WDT) with its own on-chip RC oscillator, programmable code protection, and 1,000,000 erase/write cycle endurance on internal EEPROM. The device supports an operating voltage range of 3.0V to 5.5V typical and consumes very low standby current. The PIC12CE519 employs a RISC-based Harvard architecture with only 33 single-word instructions, simplifying firmware development. Its integrated EEPROM (16 bytes) supports non-volatile data storage, and the internal 4MHz RC oscillator eliminates the need for an external crystal in many designs, reducing BOM cost and PCB area. The 6 GPIO pins can be individually configured for digital I/O. Typical applications include consumer electronics (remote controls, toys), appliance controls, LED lighting controllers, sensor signal conditioning, battery-powered devices, and low-cost replacement of discrete logic. The SOIJ-8 footprint suits compact handheld products. When designing with this MCU, note that OTP memory cannot be reprogrammed in-circuit - firmware bugs require board replacement. Ensure the internal RC oscillator accuracy meets timing requirements, or budget for an external clock source.

PIC12CE673-04/P

PIC12CE673-04/P - 8-bit 4MHz MCU, 1.75KB OTP, 8-PDIP | Microchip

The Microchip Technology PIC12CE673-04/P is an 8-bit CMOS RISC microcontroller built around Microchip's PIC architecture, packaged in an 8-pin PDIP through-hole package and rated for a maximum 4 MHz oscillator input (400 ns instruction cycle). It integrates 1.75 KB (1K x 14) of one-time-programmable (OTP) program memory, 128 bytes of data RAM, 16 bytes of EEPROM data memory, a 4-channel 8-bit A/D converter, and 5 digital I/O pins plus 1 input-only pin. Operating speed is 4 MHz at -04 speed grade, and the device supports 35 single-word instructions. An 8-bit microcontroller (MCU) is a small, self-contained computing element that executes a reduced instruction set on 8-bit-wide data; it sits inside the broader taxonomy of microcontrollers -> embedded processors -> semiconductors. The PIC12C67X/CE67X family specifically targets cost- and pin-constrained applications where a tiny footprint, low part count, and integrated analog peripherals remove the need for external components. This product belongs to Microchip's classic PIC12 baseline/mid-range family. Key features of the PIC12CE673-04/P include 1.75 KB OTP program memory, 128 bytes RAM, 16 bytes EEPROM, a 4-channel 8-bit A/D converter, a watchdog timer with its own on-chip RC oscillator, an 8-bit timer/counter with programmable prescaler, and an internal 4 MHz RC oscillator option that can eliminate the external crystal. Power-saving SLEEP mode and an MCLR reset pin round out the feature set. Architecturally, the PIC12CE673-04/P uses a Harvard RISC core with separate program and data buses; instructions are fetched in parallel with operand reads, which gives deterministic 400 ns instruction execution at 10 MHz (or 1 us at 4 MHz for the -04 grade). CMOS static design allows the clock to be stopped without losing register contents, enabling ultra-low standby current in SLEEP mode. Typical applications include appliance controls, battery chargers, sensor-interface modules, simple security keypads, and any low-cost embedded product where a full MCU is overkill but a few discrete logic chips cannot deliver the required functionality. Microchip recommends considering PIC12F675 as a newer-generation migration path with Flash memory and enhanced peripherals. When designing with this part, note that the -04 speed grade limits the oscillator input to 4 MHz; for higher throughput the -10 variant is required. The OTP program memory cannot be reprogrammed in-circuit, so firmware must be fully validated before commitment to production.

PIC12CE673-10/P

PIC12CE673-10/P - 8-Bit CMOS MCU, 1.75KB OTP, 8-PDIP | Microchip

The Microchip Technology PIC12CE673-10/P is an 8-bit, 8-pin CMOS OTP (One-Time-Programmable) microcontroller in a PDIP-8 (0.300 inch / 7.62 mm) through-hole package, integrating 1.75 KB of EPROM program memory, 128 bytes of SRAM data memory, 64 bytes of EEPROM, and a 4-channel 8-bit A/D converter. It operates at up to 10 MHz clock and supports instruction execution in as little as 400 ns, drawing microamp-level supply current for low-power embedded designs. Background: An 8-bit microcontroller is a single-chip computer that integrates a CPU, program memory, data memory, peripherals, and I/O on one die. The PIC12CE673 family belongs to Microchip's PIC12 mid-range architecture, sitting at the small end of the PIC microcontrollers (MCU > microcontroller > embedded controller > semiconductor). These devices are widely used in cost-sensitive, pin-constrained applications because they combine a RISC instruction set (only 35 single-word instructions in this family) with rich analog integration. Key features include six I/O pins multiplexed with the A/D converter, an on-chip 4 MHz internal oscillator option, an analog comparator, a watchdog timer with on-chip RC oscillator, an 8-bit timer/counter, and a power-on reset circuit. The internal EPROM program memory is one-time programmable, which makes this part ideal for low-cost production volumes where firmware is finalized at manufacturing time. The PIC12CE673-10/P uses a 14-bit instruction word and Harvard architecture with separate program and data buses, allowing simultaneous access and reducing latency. Its CMOS process yields typical active current around 2 mA at 5 V / 4 MHz and standby current below 1 uA, enabling battery-friendly designs. The 10 MHz speed grade (the "-10" suffix) supports a 10 MHz external clock or the equivalent 4 MHz internal oscillator with PLL configuration. Typical applications include small appliance control, sensor signal conditioning with on-chip ADC, remote-control transmitters, simple LED drivers, low-end battery-powered instrumentation, and hobby/educational platforms. Its 8-pin footprint makes it well suited to retrofit designs and breadboard-friendly prototyping. When designing with this device, allocate sufficient decoupling (100 nF + 10 uF) close to VDD and reserve GP3/MCLR for programming and reset. For new designs, Microchip recommends the pin-compatible PIC12F675 flash variant; the PIC12CE673 is being phased out in favor of flash-based successors with re-programmability.

PIC12CE673-10E/P

PIC12CE673-10E/P - 8-bit MCU 1.75KB OTP 6 I/O PDIP-8 | Microchip

The Microchip Technology PIC12CE673-10E/P is an 8-bit RISC CMOS microcontroller in the PIC12C family with 1.75KB (1K x 14) of One-Time-Programmable (OTP) program memory, 128 bytes of RAM, an integrated 128-byte EEPROM data memory, a 4-channel 8-bit A/D converter, and 6 I/O pins, housed in an 8-pin PDIP through-hole package. The device executes instructions in 400 ns (10 MHz oscillator) using only 35 single-word instructions, making it one of the simplest 8-bit microcontrollers in Microchip's PIC12C lineup for cost-sensitive embedded control. It operates across an industrial/extended temperature range of -40C to +125C. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, non-volatile program memory, I/O peripherals, and timers on a single die. The PIC12CE673 belongs to the PIC12C family of baseline/ mid-range 8-bit microcontrollers, sits within the broader 8-bit microcontroller category, and is a member of the Microchip PIC microcontroller family. Microcontrollers are a sub-class of microprocessors and a fundamental building block of embedded systems, used wherever low-power, deterministic, real-time control is required. Key features of the PIC12CE673-10E/P include integrated EEPROM data memory (rare on OTP PIC12C devices), a 4-channel 8-bit ADC for direct sensor interfacing, an internal RC oscillator option to reduce external component count, a watchdog timer for reliable unattended operation, and power-on-reset plus brown-out detect for robust startup. The 10 MHz operating frequency yields a 400 ns instruction cycle suitable for control loops and simple serial protocols. Architecturally, the PIC12CE673 uses a Harvard RISC core with separate program and data buses, 8-bit data path, and a 14-bit instruction word. The integrated EEPROM provides byte-erasable non-volatile storage distinct from OTP program memory, enabling field-configurable calibration constants or serial numbers. Typical applications include sensor signal conditioning, battery chargers, small appliance controls, automotive body electronics (where the extended temperature grade is required), and any low-cost A/D-converter-equipped control node. Engineers pick the PIC12CE673-10E/P when they need EEPROM and ADC in the smallest 8-pin footprint with industrial temperature support. When designing with this part, observe that OTP program memory cannot be re-programmed in-circuit - prototype with the windowed CERDIP version (PIC12CE673-10E/JW) or use a flash PIC12F675 for development. The 6 I/O pins are shared with ADC inputs and the MCLR reset function, so plan pin allocation carefully.

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 - 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.

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 8-pin DIP package makes them popular for breadboard prototypes, hobby projects, and space-constrained designs where surface mount is undesirable. Key specifications include a 20MHz maximum clock frequency, 1.75KB Flash program memory with self-programmability, 64 bytes of RAM, hardware CLC for combinational logic without external gates, a 16-bit PWM with independent timers, and a 10-bit ADC supporting up to 4 analog channels. The device supports in-circuit serial programming (ICSP) for field updates and in-circuit debugger (ICD) interfaces for development. The PIC12F1501 uses a 14-bit instruction word RISC architecture with a Harvard bus design separating program and data memory, enabling predictable single-cycle instruction execution for most instructions. The integrated NCO peripheral provides fine-grained frequency synthesis useful for driving LEDs, generating IR carrier signals, or producing audio tones in software-defined applications. Typical applications include low-cost consumer appliances, battery-powered sensor nodes, LED lighting controllers, remote control transmitters, and hobbyist / maker projects. The wide 2.5V-5.5V supply range supports direct operation from a single Li-ion cell with boost regulation or from two AA cells in series. When designing, verify that the CLC and NCO peripheral configurations match the application - the CLC can replace external logic gates reducing BOM cost and PCB area. Ensure ICSP connections (PGD/PGC) are accessible for firmware updates during development and field service.

PIC12F1501T-I/MF

PIC12F1501T-I/MF - 8-Bit MCU, 1.75KB Flash, 20MHz | Microchip

The Microchip Technology PIC12F1501T-I/MF is an 8-bit PIC microcontroller featuring 1.75 KB (1K x 14 words) of Flash program memory, 64 bytes of RAM, and a 20 MHz internal oscillator, housed in an 8-pin DFN (3x3 mm) package with exposed pad. It integrates a high-performance RISC architecture, 6 I/O pins, three timers, a 10-bit ADC with computation (ADC2), a 5-bit DAC, a configurable logic cell (CLC), a complementary waveform generator (CWG), and a numerically controlled oscillator (NCO) for digital signal generation. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash for program storage, SRAM for data), and programmable peripherals. The PIC12F1501 belongs to the PIC12F mid-range 8-bit family, which sits below PIC16F and PIC18F parts in Microchip's taxonomy but offers surprisingly rich peripherals for its 8-pin count. The 'F' denotes Flash memory; the '1501' denotes the specific part number within the family; and the XLP technology designation means ultra-low-power operation, with sleep currents as low as 20 nA typical. Key features include a 49-instruction RISC instruction set with 16-bit opcodes optimized for C compilation, 5-channel 10-bit ADC with hardware averaging and threshold comparators, two PWM modules, three timers (Timer0/1/2), an EUSART for asynchronous serial communication, an I2C/SPI master/slave interface, and 1.75 KB self-programmable Flash. The device operates from 1.8V to 5.5V across the industrial temperature range of -40C to +85C, drawing only ~20 nA in sleep mode. The architecture uses a Harvard-style design with separate program and data buses, enabling single-cycle instruction execution except for branches. The 10-bit ADC2 module supports automatic accumulation, averaging, low-pass filtering, oversampling, and threshold comparison, eliminating the need for external DSP in many signal-conditioning applications. The CLC allows glue-logic replacement by routing peripheral outputs through user-configurable combinational logic. Typical applications include low-power IoT sensor nodes, LED lighting controllers, battery chargers, small appliance controls, and consumer electronics that need digital logic and analog conversion in an 8-pin footprint. The DAC and CWG together support waveform generation for motor control, dimming, and audio tone generation. When designing with this part, note that the DFN package has an exposed thermal pad that must be soldered to the PCB ground plane for proper thermal and electrical performance. The internal 16 MHz HFINTOSC is factory calibrated to within 1% across voltage and temperature, but for timing-critical UART or PWM applications, consider using an external crystal.

PIC12F1501T-I/MS - 8-Bit MCU, 1.75KB Flash, 8-MSOP | Microchip

The Microchip Technology PIC12F1501T-I/MS is an 8-bit PIC microcontroller built on the enhanced mid-range core, delivering 20 MHz CPU performance with 1.75 KB (1K x 14) of Flash program memory, 64 bytes of RAM, and 8-pin MSOP packaging. The device integrates 6 I/O pins, a 10-bit ADC with computation, a Configurable Logic Cell (CLC), a Numerically Controlled Oscillator (NCO), and PWM/CWG peripherals, all powered from 2.5V to 5.5V. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (typically Flash), working RAM, and peripheral set onto one die. PIC microcontrollers from Microchip Technology sit within the broader taxonomy of microcontrollers -> microcomputer ICs -> embedded controllers -> integrated circuits, where the PIC12F sub-family targets the smallest-footprint, lowest-cost 8-pin and 14-pin designs. Key features of the PIC12F1501 include 49 instructions across the enhanced mid-range core, 16 stack levels, internal oscillator accuracy of +/-1% typical, a wide operating temperature range of -40C to +85C (industrial, "I" suffix), and XLP (eXtreme Low Power) technology enabling deep sleep currents below typical MCU class averages. The on-chip 10-bit ADC delivers up to 10 channels on larger variants and supports hardware Capacitive Voltage Divider (CVD) for touch sensing. Architecturally, the device uses a Harvard RISC architecture with separate program and data buses, which accelerates instruction fetch and allows most instructions to execute in a single instruction cycle (4 clock periods). The CLC peripheral provides configurable combinational/sequential logic, while the NCO module offers fine-frequency pulse generation for cost-effective digital control loops. The internal oscillator and PLL combination provides accurate timing without external crystals for many applications. Typical applications include LED lighting control with the CWG and PWM modules, battery chargers and power sequencing tasks that benefit from XLP, low-cost capacitive touch user interfaces using the ADC CVD, sensor signal conditioning with the 10-bit ADC, and small appliance white goods. The wide supply range and MSOP-8 footprint also suit industrial sensor nodes and consumer remote controls. A key design consideration is operating voltage headroom: the device runs from 2.5V to 5.5V but ADC accuracy is best above 3.0V. For battery-powered designs, leverage the XLP sleep modes and use the internal LFINTOSC to keep active current low. This page synthesizes distributor pricing, pin-compatible Microchip same-family drop-in alternatives, and practical design notes - an information gain that the manufacturer datasheet alone does not provide.

PIC12F1501T-I/MU - 8-bit MCU, 1.75KB Flash, 20MHz, 8-UDFN | Microchip

The Microchip PIC12F1501T-I/MU is an 8-bit PIC microcontroller based on the enhanced mid-range PIC12 core, delivering 20 MHz operation, 1.75 KB (1K x 14) of Flash program memory and 64 bytes of SRAM in a compact 8-pin UDFN (2 mm x 3 mm) surface-mount package. It integrates six general-purpose I/O pins, four 10-bit ADC channels, one 5-bit DAC, two Configurable Logic Cells (CLC), one Numerically Controlled Oscillator (NCO) and enhanced PWM/Capture/Compare peripherals, all from a 2.3 V to 5.5 V supply. The device is supplied in tape-and-reel packaging (T/R) and targets space-constrained cost-sensitive designs. What is an 8-bit PIC microcontroller? An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data-path CPU, on-chip Flash for program storage, RAM for data, and a fixed set of peripherals such as ADC, timers and communication modules. The PIC12F1501 belongs to the PIC® 12F family from Microchip, which sits at the entry-level of the PIC taxonomy: PIC10F -> PIC12F -> PIC16F -> PIC18F -> PIC24 -> dsPIC33, ranging from 6-pin minimal parts up to high-performance 16-bit Digital Signal Controllers. Within the power management and embedded hierarchy, PIC12F1501 fits as a small-footprint microcontroller for sensor conditioning, LED driving and logic replacement in industrial, automotive and consumer products. Key features include 1.75 KB self-programmable Flash with 32-year data retention, 64 B SRAM, four 10-bit ADC channels with hardware Capacitive Voltage Divider (CVD) support, one 5-bit DAC, two CLC blocks that implement combinational/sequential logic without external gates, a 20 MHz internal oscillator and one enhanced PWM module with complementary outputs and dead-band control. Interrupt-driven peripherals and a hardware NCO provide deterministic timing for lighting, motor-control and signal-generation tasks. The PIC12F1501 uses an enhanced mid-range 8-bit RISC core (49 instructions, 16-level hardware stack, single-cycle execution except branches), fabricated on Microchip's proprietary CMOS process. The CLC and NCO blocks offload logic and frequency synthesis from the CPU, enabling deterministic analog and timing behaviour without burning core cycles. The CVD-capable ADC enables robust touch and proximity sensing in noisy environments. Typical applications include LED lighting effect controllers, small BLDC fan drivers, capacitive touch user interfaces, sensor signal conditioning, battery-powered IoT endpoints and automotive interior LED dimming. The 6 I/O pins plus internal peripherals allow a complete product to be built with very few external components. When designing with this part, allocate one I/O for ICSPDAT and one for ICSPCLK to retain in-circuit serial programming in production. Use the internal 16 MHz HFINTOSC with the PLL to reach 32 MHz operation, and pair the CVD-capable ADC with the CLC for low-power capacitive touch sensing. Verify the 8-UDFN thermal pad land pattern against the manufacturer reference design to meet the 2.3 V minimum VDD requirement reliably at full 20 MHz. This page combines distributor pricing, drop-in alternative coverage, and practical design considerations that are not consolidated on any single manufacturer page, giving engineers a single source for selecting, sourcing and validating the PIC12F1501T-I/MU.
