PIC12F675T-E/SN - 8-Bit 20MHz MCU 1.75KB Flash SOIC8 | Microchip

The Microchip Technology PIC12F675T-E/SN is an 8-bit CMOS Flash-based PIC microcontroller in an 8-pin SOIC (SN) package, designed for low-power embedded applications with extended temperature operation. It features a 20MHz maximum clock, 1.75KB (1K x14 words) of Flash program memory, 64 bytes of SRAM, and 128 bytes of EEPROM data storage, plus a 10-bit 4-channel ADC. The 'T' suffix denotes Tape & Reel packaging for high-volume assembly, while 'E' indicates the extended -40C to +125C industrial operating temperature range. A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory, working RAM, peripherals, and I/O. PIC microcontrollers use a RISC (Reduced Instruction Set Computer) architecture, executing each instruction in a single cycle (200ns at 20MHz), enabling deterministic timing. The PIC12F family targets cost- and pin-constrained designs where 6-8 pins are sufficient. The 12F675 specifically adds a 10-bit ADC and on-chip EEPROM, distinguishing it from the lower-cost 12F629 sibling that lacks these features. Key features include 35 single-word instructions, only 8.5 uA operating current at 32 kHz and 100 uA at 1 MHz, a 1 nA typical standby current, an internal 4MHz/8MHz oscillator, and a wide 2.0V to 5.5V supply range. The device also integrates brown-out reset, power-on reset, watchdog timer, and an enhanced PWM module. These features make it ideal for battery-powered and energy-harvesting applications where quiescent current dominates total energy consumption. The architecture is built around a Harvard-style RISC core, separate program and data buses, and on-chip debug via ICD. The 10-bit ADC with 4 input channels can be used for sensor signal acquisition such as temperature, voltage, or current monitoring. The internal oscillator eliminates external crystal components in cost-sensitive layouts, while the industrial temperature grade allows deployment in uncontrolled environments. Typical applications include battery chargers, LED lighting controllers, sensor conditioning nodes, smoke and gas detectors, small appliance control, automotive body electronics, and IoT edge nodes. The combination of low power consumption, integrated peripherals, and small form factor also makes the part popular in retrofit industrial sensor modules. When designing with the PIC12F675T-E/SN, ensure decoupling capacitors of at least 0.1 uF are placed within 5mm of the VDD pin, and reserve one GPIO for the ICSP programming interface (PGD/PGC). For ADC accuracy, average multiple samples and use the internal voltage reference for ratios that are insensitive to absolute reference drift.

The Microchip Technology PIC12F675T-I/MD is an 8-bit Flash-based CMOS microcontroller in the PIC12F family, packaged in an 8-lead DFN (4x4 mm, exposed pad) with tape and reel packaging. It integrates a 20 MHz core, 1.75 KB (1K x 14 words) of Flash program memory, 64 bytes of RAM, 128 bytes of EEPROM, a 10-bit ADC with 4 channels, and an on-chip 4 MHz internal oscillator. The device operates from 2.0V to 5.5V and features 6 general-purpose I/O pins. What is a Flash-based 8-bit microcontroller? An 8-bit microcontroller is a small computer-on-a-chip that processes data in 8-bit chunks and integrates CPU, memory (Flash for program storage, RAM for data, EEPROM for non-volatile data), peripherals (ADC, timers, communication), and I/O on a single die. Flash memory allows in-circuit reprogramming via ICSP, making these MCUs ideal for prototyping, low-volume production, and field-upgradable designs. PIC microcontrollers are widely used in cost-sensitive embedded applications due to their deterministic RISC architecture, low power consumption, and a 35-instruction set that simplifies firmware development. The PIC12F675 delivers 200 ns instruction execution, hardware UART, comparators, and an enhanced PWM module. Its nanopower technology provides low sleep current for battery-operated designs. The integrated 10-bit ADC with 4 channels eliminates external analog components in many sensing applications. Six GPIO pins support direct interfacing to sensors, switches, LEDs, and communication lines. The device also features a programmable brown-out reset (BOR), watchdog timer, and in-circuit serial programming (ICSP) for in-field firmware updates. The architecture is built on Microchip's enhanced mid-range 8-bit RISC core with a single accumulator and hardware multiplier support. The Harvard architecture separates program (Flash) and data (RAM) buses, allowing simultaneous instruction fetch and data access. The 14-bit wide instruction word reduces code density issues common with 12-bit PIC parts. The 10-bit ADC uses successive approximation with internal or external voltage reference selection. Typical applications include low-power sensor nodes, battery management, LED lighting controllers, automotive interior electronics, consumer appliance control, and small IoT edge devices. The wide operating voltage range supports direct connection to 2xAA/3xAA battery packs as well as regulated 3.3V and 5V rails. Designers benefit from Microchip's MPLAB X IDE and XC8 compiler ecosystem, which provide free development tools. When designing with the PIC12F675, ensure ICSP programming header access is preserved on the PCB. The internal 4 MHz oscillator eliminates the external crystal in many designs, but precision timing applications should still use an external resonator or crystal. Decoupling capacitors (100 nF plus bulk) must be placed close to VDD.

Housed in an 8-pin DFN-S (6x5 mm) surface-mount package, the device integrates 6 I/O pins, a 4-channel 10-bit ADC, one comparator, and a hardware USART/SCI module, all operating from a 2.0V to 5.5V supply. The part is specified for the industrial temperature range of -40°C to +85°C. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data RAM, and configurable peripherals. The 8-bit MCU class, including the PIC12F family, is widely used in cost- and space-constrained applications that need deterministic real-time response rather than high computational throughput. PIC12F microcontrollers sit at the entry level of Microchip's 8-bit portfolio, prioritizing low pin count, low power, and ease of development with only 35 single-word instructions. Key features of the PIC12F675T-I/MF include 1.75KB self-programmable Flash, 128 bytes of EEPROM for non-volatile data storage, an internal 4MHz oscillator with software-selectable calibration, and a 10-bit ADC with 4 input channels that can also be used as digital I/O.

The device also provides an in-circuit serial programming (ICSP) interface that allows field firmware updates via two standard pins. Architecturally, the PIC12F675 uses a Harvard RISC core with a 14-bit instruction word, 8-bit data path, and a single accumulator (W register) that delivers predictable, deterministic instruction timing. The Flash memory uses a 14-bit word organization that maps to 1024 instruction words (1.75KB). The internal 4MHz oscillator and four available clock modes allow designers to balance active current consumption against execution speed, and the device supports both internal and external oscillator configurations for EMI-sensitive designs. Typical applications include battery-powered sensor nodes, consumer appliance control, LED driver controllers, simple state machines, and automotive accessory modules where AEC-Q100 grade variants (e.g., PIC12F675-I/MF in automotive screening) are acceptable. The small 8-pin DFN package is well suited for space-limited PCB designs such as remote keyless entry fobs, smart thermostats, and personal medical accessories. Designers should note that the DFN-8 (6x5 mm) exposed pad must be soldered to a sufficient copper area for thermal dissipation and electrical grounding. Decoupling capacitors of 100nF and 10µF should be placed within 3 mm of the VDD pin to ensure stable operation across the 2.0V to 5.5V supply range. For noise-sensitive ADC readings, AVSS should be tied directly to the ground plane, and the analog inputs should be guarded by digital traces.

Internal oscillator options (INTOSC 31 kHz to 8 MHz with PLL) eliminate external crystals, reducing BOM cost in price-sensitive designs. A key design consideration is the DFN exposed-pad layout: the central EP must be soldered to a thermal pad tied to ground to meet the datasheet thermal envelope. Engineers should also verify that the oscillator selection bit configuration leaves at least four usable I/O pins; with the 8 MHz INTOSC selected, GP5 becomes an oscillator pin and only five GPIOs remain. Programming is supported by Microchip's MPLAB X IDE and the XC8 compiler at no charge. This page consolidates drop-in DFN alternatives, distributor pricing as of 2026-09-15, and design notes beyond the Microchip datasheet summary to help engineers shorten the PIC12F683T-E/MF selection cycle.

PIC12F752-E/MF

PIC12F752-E/MF - 8-bit MCU 1.75KB Flash 6 I/O 20MHz | Microchip

The Microchip Technology PIC12F752-E/MF is an 8-bit PIC microcontroller built on the mid-range core, delivering 5 MIPS at 20 MHz operation and integrating 1.75 KB (1K x 14) of self-read/write Flash program memory with 64 bytes of SRAM and a 20 MHz internal oscillator in an 8-pin DFN-EP (3x3) package. The PIC12F752 family is engineered for cost-sensitive analog-intensive applications, pairing a RISC instruction set with two high-speed analog comparators (20 ns response), one Capture-Compare-PWM (CCP) module, a 9-bit DAC and four 10-bit ADC channels in a footprint that fits where 6-pin or 8-pin discretes previously ruled. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, non-volatile program memory (Flash), and peripheral interfaces on one die, optimized for deterministic real-time control rather than throughput. PIC12F devices sit at the small-pinned end of Microchip's PIC mid-range architecture, hierarchically classified as: PIC microcontroller -> PIC12 family -> PIC12F sub-family -> 8-pin OTP/Flash parts. This taxonomy matters because the PIC12F752 shares tools, instruction set, and pinout conventions with the broader PIC12F series while specializing in analog signal conditioning. Key features of the PIC12F752-E/MF include six general-purpose I/O pins (re-mappable via peripheral pin select on compatible siblings), one 8-bit and one 16-bit timer, two analog comparators with programmable reference, an enhanced PWM with auto-shutdown, and an internal 8 MHz oscillator that can be tuned across 32 kHz to 20 MHz via the OSCTUNE register. The device operates from 2.0 V to 5.5 V and includes in-circuit serial programming (ICSP) plus a 64-byte EEPROM emulation region in Flash. The architecture uses a Harvard 14-bit instruction word with a 13-bit program counter and an 8-level hardware stack, yielding deterministic interrupt latency and single-cycle instruction execution except for branches. The integrated analog peripherals allow direct interfacing to sensors without external op-amps, which is the principal reason designers select PIC12F752 over general-purpose 8-bit alternatives. NanoWatt power management offers idle, sleep and watchdog-based wake modes with currents measured in microamps. Typical applications include SMPS auxiliary control, LED lighting drivers, battery chargers, sensor signal conditioning, and small motor or fan controllers. The DFN-EP package exposes a thermal pad that doubles as an additional ground and provides low theta-JA for the modest power dissipation of this device, making it suitable for hand-held and sealed enclosures. When designing with this part, reserve pin 4 (GP3/MCLR) for either reset or digital input only - it is not a true bidirectional I/O on this family. Ensure the exposed pad is soldered to a ground plane for thermal and electrical performance. This page synthesizes distributor pricing, verified parametric data, and practical design notes not found in the manufacturer datasheet alone, supporting engineers evaluating the PIC12F752-E/MF for new designs or as a drop-in upgrade path.

PIC12F752-E/P

PIC12F752-E/P - 8-Bit 5MIPS Flash MCU | Microchip Technology

The Microchip Technology PIC12F752-E/P is an 8-bit PICmicro flash microcontroller with 1.75 KB of program memory, 64 bytes of RAM, six general-purpose I/O pins, an 8 MHz internal oscillator, and 5 MIPS processing performance, supplied in an 8-pin PDIP package. The PIC12F752-E/P uses the E temperature grade and is listed in production by Microchip, although the manufacturer identifies PIC16F1703 as a newer device. A PICmicro microcontroller is a compact RISC-based embedded controller combining flash program memory, data RAM, general-purpose I/O, oscillators, and optional analog or timing peripherals on one integrated circuit. This device belongs to the PIC12 family hierarchy, where the 12 designation identifies a small-footprint controller intended for embedded logic, sensing, and control tasks requiring modest program space and low component count. The verified device data identifies 1.75 KB, organized as 1K by 14 words, of flash program memory and 64 bytes of RAM. Its six I/O pins provide enough external connectivity for basic digital control, status indicators, switches, and simple peripheral interfaces. An 8 MHz internal oscillator supports operation without an external crystal, while the listed 5 MIPS performance rate provides ample throughput for compact control loops and sequential logic. The PIC12F752/HV752 architecture uses a 13-bit program counter capable of addressing an 8K by 14 program-memory space, although only the first 1K by 14 words are physically implemented in the PIC12F752. This architecture reduces unnecessary program-memory capacity when a design does not need a larger code space. The related HV752 family is distinguished by the inclusion of higher-voltage operating capability, so it should not be assumed to be a performance-identical substitute without reviewing the manufacturer data sheet. Typical uses include compact appliance controls, small sensor interfaces, LED status systems, simple timers, and dedicated embedded automation where an internal oscillator and a small PDIP footprint simplify prototyping and through-hole assembly. The six available I/O pins make the device most appropriate when the external interface is modest and the firmware does not require extensive communications resources. Designers should preserve adequate decoupling near the supply pins, route oscillator-sensitive signals away from switching nodes, and verify every peripheral assignment against the package-specific pin table. The temperature-grade code E and the /P package suffix must be checked against environmental and assembly requirements. Software should also be validated for clock tolerance, brownout behavior, and programming configuration before production release. This page consolidates manufacturer status information, verified distributor specifications, pricing context, compatible-package candidates, and engineering-oriented selection guidance. Its practical value is the comparison of memory organization, I/O availability, package compatibility, temperature-grade choices, and design constraints that engineers must verify before treating an alternative as a drop-in replacement.

The -E suffix denotes the extended industrial temperature grade of -40°C to +125°C, making the device suitable for harsh-environment applications. The PIC12F752's enhanced mid-range core executes 35 single-word instructions and supports hardware interrupt context saving, easing firmware architecture for motor control and power conversion. Internal oscillator calibration supports ±1% accuracy across voltage and temperature, eliminating the need for an external crystal in most designs. The 8-pin SOIC footprint simplifies hand-prototyping and rework while supporting reflow profiles compatible with lead-free surface-mount assembly per JEDEC J-STD-020. Typical applications include LED lighting controllers, BLDC motor commutation, fan control, battery chargers, sensor signal conditioning, and low-cost consumer appliances where the 6-I/O constraint fits the use case. The internal voltage reference and high-speed comparators enable primary-side regulation in flyback converters and direct comparator-based feedback loops. When designing with this part, reserve at least one I/O for in-circuit serial programming (ICSP) and use the recommended MPLAB X IDE configuration bits to select the internal oscillator and disable unused peripherals. For analog designs, allocate adequate PCB ground pour around the AVSS/AVDD pair and decouple both with 100 nF ceramic capacitors placed within 5 mm of the supply pins.

PIC12F752-I/MF

PIC12F752-I/MF - 8-Bit MCU 20MHz 1.75KB Flash 8-DFN | Microchip

The Microchip Technology PIC12F752-I/MF is an 8-bit PIC microcontroller in the PIC12F family, featuring a mid-range core running at up to 20 MHz instruction rate with 1.75 KB (1K x 14) of self-read/write Flash program memory, packaged in an 8-pin DFN (3x3 mm) with exposed thermal pad. It integrates 2 high-speed analog comparators with 20 ns propagation delay, 1 Capture/Compare/PWM (CCP) module, and an internal 8 MHz oscillator that eliminates the need for an external crystal in many designs. The device targets low-pin-count cost-sensitive applications requiring on-chip analog and digital peripherals without external components. A PIC12F-series microcontroller is a member of Microchip's 8-bit mid-range architecture family, which provides a balance of low cost, low power, and adequate processing throughput for simple embedded control tasks. PIC microcontrollers use a Harvard architecture with separate program and data buses, and the 12F sub-family specifically targets applications requiring only 6-8 I/O pins. The PIC12F752 extends the 12F line by adding two fast analog comparators and a CCP module, making it suitable for power-conversion and signal-conditioning tasks where discrete analog components would otherwise be required. Key features of the PIC12F752 include 64 bytes of SRAM, 128 bytes of EEPROM, 5 channels of 10-bit ADC, a 5-bit DAC, an enhanced PWM with dead-band control, and a 4-bit comparator with programmable reference. The device operates from 2.0 V to 5.5 V across the industrial -40C to +85C range and supports In-Circuit Serial Programming (ICSP) via two pins. The internal oscillator can be tuned to 8 MHz with ±1% accuracy after calibration, allowing designs to operate without external timing components. The PIC12F752 architecture uses a 14-bit instruction word with single-cycle execution (except branches), giving roughly 5 MIPS throughput at 20 MHz. Peripherals are mapped to a banked register file accessible through dedicated SFRs, and the core supports hardware context save/restore for interrupt-driven firmware. The analog comparators can directly trigger the CCP for hardware-based control loops such as peak-current-mode power supplies or zero-crossing detectors. Typical applications include LED lighting drivers, battery chargers, switch-mode power supply control, small motor control, sensor signal conditioning, and consumer appliance user-interface controllers. The CCP and high-speed comparator combination is particularly well suited to peak-current-mode converters and synchronous rectifier timing. When designing with the PIC12F752, note that the device has only 6 general-purpose I/O pins. Designers must plan pin allocation carefully when using ICSP (which consumes two pins) and the analog peripherals simultaneously. The internal oscillator accuracy is sufficient for UART-free applications but external timing is recommended for serial communication. A decoupling capacitor of 100 nF placed within 5 mm of the VDD pin is recommended per Microchip's analog design guidelines.

PIC12HV609-E/MS - 8-bit Flash MCU, 1.75KB, 8MSOP | Microchip

The Microchip Technology PIC12HV609-E/MS is an 8-pin, 8-bit flash-based CMOS microcontroller from the PIC12 family, featuring 1.75 KB of Flash program memory (1K x 14), 64 bytes of RAM, and 6 I/O pins housed in an 8-MSOP (MS) package. It integrates an internal 8 MHz oscillator and supports instruction execution up to 20 MHz when driven from an external source, while the high-voltage (HV) variant accepts an unregulated supply up to the maximum VDD rating without requiring a local regulator on the input rail. What is a PIC12 microcontroller? The PIC12 family is Microchip's baseline 8-bit mid-range microcontroller line, using a RISC-style Harvard architecture with a small instruction set (typically 35 instructions), single-cycle execution at the system clock, and integrated peripherals such as comparators, timers, and a watchdog. Within the broader hierarchy, PIC12 sits below PIC16/PIC18, and PIC microcontrollers belong to the 8-bit microcontroller category of embedded semiconductors. Key features of the PIC12HV609-E/MS include 1.75 KB Flash (1K x 14 words), 64 bytes RAM, an 8 MHz internal oscillator, one 8-bit timer (TMR0), one 16-bit timer (TMR1), an enhanced mid-range core with 35 instructions and 8 hardware stack levels, 25 mA source/sink I/O drive, and a user-configurable analog comparator with hysteresis. The HV prefix means the device includes a built-in shunt regulator, allowing direct operation from 2.0 V to user-defined maximum (typical application: unregulated battery or rectified supply) without external regulation. The -E suffix denotes the -40C to +125C extended industrial temperature grade. Architecturally, the PIC12HV609 uses the same enhanced mid-range core as the standard PIC12F609, but with an internal shunt regulator front-end instead of a direct VDD pin. This internal regulator drops the high input voltage down to the core's regulated logic rail, simplifying designs that would otherwise require external zener or LDO regulators. Program memory is Flash and self-programmable under software control, supporting in-circuit serial programming (ICSP). Typical applications include battery-powered products where an unregulated stack must feed the MCU directly (HV variant specific), consumer appliances, simple sensor conditioning nodes, automotive body electronics within the -40C to +125C range, low-cost motor control loops, and any general-purpose 8-bit replacement for legacy PIC10/PIC12 designs requiring a small pin-count footprint. The device also fits remote controls, lighting controllers, and standby controllers in white goods. When designing with this part, leave adequate ground copper under the exposed MSOP pad for thermal relief, place the 0.1 uF VDD decoupling capacitor within 2-3 mm of the VDD pin, and ensure ICSP connections (PGD/PGC) are accessible for production programming. The internal shunt regulator dissipates significant power at high input voltages, so derate VDD_MAX by application voltage to stay within the thermal envelope.

The Microchip PIC12HV609-E/P is an 8-bit Flash-based CMOS microcontroller in an 8-pin PDIP package, built on Microchip's mid-range PIC core with 35 instructions and 8 hardware stack levels. It integrates 1.75 KB of Flash program memory, 64 bytes of RAM, and a high-voltage shunt regulator (4 mA to 50 mA range) that allows direct operation from a high-voltage supply without a separate 5V regulator. The device runs from 2.0V to user-defined HV input with internal 4 MHz or 8 MHz oscillator options, providing flexible timing for cost-sensitive embedded designs. A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, timers, I/O peripherals, and interrupt logic. Within the broader taxonomy, the PIC12HV609 belongs to the 8-bit microcontroller class -> RISC microcontroller family -> embedded controller -> semiconductor IC. The PIC12HV609 specifically sits in the PIC10/12/16 mid-range family, characterized by a 14-bit instruction word, 8-level hardware stack, and the lowest pin counts in the Microchip portfolio (6/8/14 pin). The "HV" prefix indicates the integrated shunt voltage regulator, which is the defining feature distinguishing it from the standard PIC12F609 variant. Key features include 5 general-purpose I/O pins plus 1 input-only pin with 25 mA source/sink capability for direct LED drive, individually programmable weak pull-ups, an analog comparator with programmable on-chip voltage reference, one 8-bit timer (TMR0), one 16-bit timer (TMR1), watchdog timer (WDT), enhanced power-on reset, brown-out reset (BOR), and in-circuit serial programming (ICSP). The wide operating voltage range and high-current I/O eliminate many external components typically required by competing MCUs. Architecture-wise, the device uses a Harvard architecture with separate program and data buses, allowing simultaneous instruction fetch and data access. The mid-range core executes one instruction per clock cycle (except branched instructions), delivering ~1 MIPS at 4 MHz. The integrated shunt regulator uses an external resistor network tied to the HV pin, providing regulated VDD for the core from a higher-voltage source. Typical applications include AC line-powered appliance control, LED lighting drivers, battery chargers, smart sensors, white goods control boards, and any cost-sensitive embedded application requiring a high-voltage-tolerant MCU without an external regulator. The high-voltage shunt simplifies isolated offline designs where a small switching supply feeds the HV pin directly. When designing with this part, choose the shunt resistor value based on the expected supply current (typically 4-50 mA range) and verify power dissipation in the shunt element. For battery applications where the HV input is not used, consider the PIC12F609 family instead to avoid quiescent current draw through the shunt path.

It runs up to 20 MHz instruction rate from a wide 2.0V–5.5V supply, with the unique HV variant capable of operating directly from a 2.5V/3.3V/5V bus without a separate regulator stage. An 8-bit microcontroller (MCU) is a small computer-on-a-chip that combines a CPU, non-volatile program memory (Flash), working RAM, and peripheral set into one package. Within the broader embedded hierarchy, the PIC12HV609 belongs to the PIC10/12/16 mid-range core family, itself a sub-family of Microchip's 8-bit PIC microcontrollers, which in turn sit inside the embedded MCU category of integrated circuits. The "HV" prefix indicates an integrated shunt regulator, allowing direct supply from higher-voltage rails without external regulation — a useful differentiator in low-component-count designs. Key features include an internal 4/8 MHz precision oscillator, a user-configurable comparator with hysteresis, one 8-bit timer (TMR0), one 16-bit timer (TMR1), a watchdog timer (WDT), brown-out reset (BOR), power-on reset (POR), in-circuit serial programming (ICSP), and 25 mA source/sink I/O drive. Six GPIO pins are available, of which five are multiplexed with analog comparator and timer inputs. The -E suffix denotes the extended -40 °C to +125 °C industrial temperature grade, and the /SN suffix specifies the 8-SOIC (3.90 mm) package. Architecturally, the device uses Microchip's 14-bit instruction word mid-range core with 8-level hardware stack and 35 instructions, providing deterministic interrupt latency and Harvard bus separation. The high-voltage shunt regulator on the VDD pin simplifies power design in battery and bus-powered applications where a low-cost Zener-resistor supply would otherwise be required. Typical applications include low-power sensor nodes, LED driver controllers, simple state machines, automotive body electronics (AEC-Q100 qualified), battery chargers, and consumer white-goods control. The wide voltage range and integrated HV regulator make it especially attractive for cost-sensitive 5 V or 12 V appliances and for replacing discrete logic plus Zener diode combinations. When designing with this device, note that only one comparator is provided — analog-heavy designs should consider the PIC12F617 or PIC12F1501 instead. Decoupling the VDD pin with a 100 nF ceramic capacitor placed within 3 mm of the pin is essential for stable HV regulator operation.

PIC12HV609-I/MS - 8-bit Flash MCU 1.75KB 20MHz MSOP-8 | Microchip
PIC12HV609-I/MS

PIC12HV609-I/MS - 8-bit Flash MCU 1.75KB 20MHz MSOP-8 | Microchip

The Microchip Technology PIC12HV609-I/MS is an 8-bit flash-based CMOS microcontroller from the PIC® 12F family, housed in an 8-pin MSOP package with a 20 MHz maximum CPU clock, 1.75 KB (1K x 14 words) of flash program memory, and 64 bytes of data RAM. The 'HV' suffix indicates integrated high-voltage support that allows the device to operate directly from a 2.0 V to user-defined VDD source and to handle higher-voltage I/O switching through internal shunt regulator circuitry. An 8-bit PIC microcontroller is a RISC-class single-chip MCU built around a Harvard architecture with separate program and data buses. The PIC12F/12HV family targets low-pin-count, cost-sensitive embedded applications where minimal BOM, on-chip peripherals, and nanoWatt sleep modes outweigh the need for higher MIPS. In a typical product taxonomy: PIC12HV609 -> PIC12F series -> PIC12 family -> PIC10/12/14/16/18 mid-range 8-bit MCU lineup -> Microcontroller -> Microprocessors & Controllers -> Semiconductors. Each PIC12 core executes one instruction per clock cycle (excluding branches), delivering ~5 MIPS at 20 MHz. Key differentiating features include: 1.75 KB self-programmable flash with 100K endurance cycles, 64 bytes SRAM, 128 bytes EEPROM, an internal 8 MHz oscillator (with optional 31 kHz LF oscillator), six I/O pins with individual direction control, an 8-bit timer (TMR0) with an 8-bit prescaler, a 16-bit timer (TMR1), an enhanced PWM/capture/compare (ECCP) module, a 10-bit ADC with 4 input channels, a comparator with hysteresis, and the high-voltage shunt regulator that lets the chip run from 2.0 V-5.5 V with internal regulation. The MSOP-8 package has a typical theta-JA of ~206 C/W and supports industrial -40C to +85C operation. Architecturally, the device uses a 14-bit instruction word with a 35-instruction RISC core, an 8-level hardware stack, and Microchip's nanoWatt Technology for sub-microamp sleep currents. The HV shunt regulator eliminates the need for an external regulator in 9V/12V battery or industrial bus applications, while the integrated ADC and comparator allow direct sensor conditioning without an external analog front end. Typical applications include 9V/12V battery-powered sensor nodes, AC line-voltage zero-cross detection (via high-voltage tolerant I/O), fan-speed control loops, white-goods user-interface panels, and low-cost IR remote transmitters where the 20 MHz core delivers ample headroom for RC5/SIRC protocols. The HV regulator is also valuable in industrial 24V systems where the MCU can be powered directly from the bus through a series Zener. When designing with this part, ensure the HV shunt regulator's current limit (sometimes called 'zener current') is respected: total current draw through the regulator must remain within the device's specification, otherwise internal heating may exceed the package's thermal envelope. For designs not requiring high-voltage tolerance, the PIC12F609 in the same MSOP-8 pinout is a drop-in lower-cost option.

PIC12HV609-I/P

PIC12HV609-I/P - 8-bit Flash MCU, 1.75KB Flash, 8MHz, PDIP-8

The Microchip Technology PIC12HV609-I/P is an 8-bit, 8-pin Flash-based CMOS microcontroller in the PIC12 mid-range family, supplied in a PDIP-8 (through-hole) package. It integrates 1.75 KB (1024 x 14) of self-programmable Flash program memory, 64 bytes of data RAM, and an internal 8 MHz oscillator (selectable to 4 MHz or 31 kHz LF), allowing standalone operation without an external crystal. The device supports supply voltages of 2.5 V, 3.3 V, or 5 V and is qualified for the industrial -40C to +85C operating range. A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, I/O peripherals, and clock generation. The 8-bit PIC architecture uses a RISC instruction set with 35 single-word instructions and a 200 ns instruction cycle at 20 MHz, simplifying code generation in MPLAB X IDE while keeping deterministic real-time response. The PIC12 sub-family specifically targets space-constrained, low-pin-count applications such as appliance control, sensor front-ends, and battery-powered devices. Key features include four timers (Timer0, Timer1, Timer2, WDT), one enhanced Capture/Compare/PWM (ECCP) module, two analog comparators with selectable references, 6 general-purpose I/O pins, an internal shunt regulator for high-voltage operation (the "HV" suffix), Brown-Out Reset (BOR), Power-On Reset (POR), and an ICD debug interface. The PIC12HV609 is electrically identical to the PIC12F609 but adds an internal shunt regulator, allowing direct operation from supplies up to ~13.5 V without an external 5V regulator. Typical applications include LED lighting drivers, battery chargers, power-supply auxiliary controllers, smoke detectors, fan controls, and small appliance interfaces. The combination of Flash memory, internal oscillator, and high-voltage tolerance minimizes external component count. When designing with the PIC12HV609-I/P, verify that the high-voltage (HV) shunt current rating matches your supply; the internal shunt dissipates Vdd_delta * I_shunt. Always use a 0.1 uF decoupling capacitor within 5 mm of the Vdd pin and keep the ICSP clock/data traces short for reliable in-circuit programming.

The HV variant integrates a 5.1V-13V shunt regulator on the supply pin, allowing direct connection to rectified mains or higher DC buses without an external regulator. Brown-out reset, power-on reset, and a watchdog timer provide system reliability. Designed for fan control, LED lighting, and high-voltage sensing applications, the PIC12HV609's enhanced PWM and integrated HV shunt simplify closed-loop BLDC and brushless fan designs. The Harvard RISC architecture executes instructions in a single cycle, achieving 200ns instruction time at 20MHz. Primary uses include BLDC ceiling fan motor control, AC-line-powered LED drivers, appliance controls, and low-cost high-voltage sensor interfaces. Industrial temperature range suits automotive and appliance environments. The 8-pin SOIC footprint enables compact designs while preserving easy hand-soldering. When designing with this device, ensure the shunt regulator current budget matches the application - the internal shunt dissipates excess voltage as heat. For AC mains rectification applications, isolate the digital logic from line-voltage transients with adequate PCB clearance and TVS protection.
