PIC12HV609-E/P

PIC12HV609-E/P - 8-bit Flash MCU, 1.75KB, 8-Pin PDIP | Microchip

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

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.

PIC12HV609T-I/MD - 1.75KB Flash 8-bit MCU | Microchip | 8-DFN

The Microchip Technology PIC12HV609T-I/MD is an 8-bit flash-based CMOS microcontroller in the PIC12 family, offered in an 8-pin DFN-EP surface-mount package (3 x 3 mm, 0.90 mm height) and supplied on Tape and Reel. It integrates 1.75 KB of flash program memory, 64 bytes of RAM, and an internal 8 MHz oscillator, and operates across an industrial -40C to +85C temperature range at 2.5V/3.3V/5V supply rails. A PIC microcontroller (MCU) is a single-chip computer that combines a RISC CPU core, non-volatile flash program memory, RAM, and configurable peripherals around a compact die. The PIC12HV609 specifically is a low-pin-count (8-pin) member of Microchip's mid-range PIC family, optimized for cost-sensitive embedded applications where board area and BOM count matter more than raw computational throughput. It belongs to the broader hierarchy: 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. Key features of the PIC12HV609T-I/MD include a 20 MHz maximum CPU clock via the internal oscillator block, hardware timers (Timer0/Timer1/Timer2), a 10-bit Analog-to-Digital Converter (ADC) on selected pins, and a comparator with a programmable voltage reference.

The device uses Microchip's enhanced mid-range 8-bit RISC architecture with 35 single-word instructions and a 14-bit instruction word. Two I/O pins are 5V-tolerant on most variants, supporting mixed-voltage digital interfaces. The on-chip in-circuit serial programming (ICSP) interface lets the same chip be programmed after PCB assembly using only two signal lines, eliminating programming sockets and reducing manufacturing cost. Typical applications include low-power sensor nodes, LED controllers, battery chargers, smoke detectors, and small appliance controls. The wide supply range (2.5V-5V) and built-in brown-out reset make it suitable for unregulated mains-powered or battery-powered systems. Industrial designs favor the -40C to +125C extended parts (PIC12HV609-E/MD), while the -I grade PIC12HV609T-I/MD is specified for commercial and light-industrial environments. A key design tip is that the internal shunt regulator of the "HV" variant dissipates significant power when fed from a high-voltage source. At 9V VIN and 5 mA internal draw, expect roughly 20 mW of continuous dissipation, so the exposed pad (EP) must be soldered to a copper pour for thermal relief. Layout this ground pad generously to keep junction temperature in check.

PIC12HV615-I/MD - 8-bit 20MHz 1.75KB Flash MCU | Microchip

The Microchip PIC12HV615-I/MD is an 8-bit flash-based CMOS microcontroller in the PIC12 family, featuring 1.75KB (1K x 14) of Flash program memory, 64 bytes of RAM, and 6 I/O pins, housed in an 8-pin DFN (4x4 mm) surface-mount package. It operates from a 2.0V to 5.5V supply with a maximum clock speed of 20MHz, and is qualified for the industrial temperature range of -40C to +85C. An 8-bit microcontroller (MCU) is a small, self-contained computing device built around an 8-bit data path and an integrated CPU, memory, and peripherals on a single silicon die. PIC microcontrollers implement Microchip's proprietary RISC architecture, executing instructions in a single cycle (200 ns at 20MHz) from a compact 35-instruction set, balancing low power, deterministic timing, and code efficiency. PIC12-family devices sit at the low-end of the PIC hierarchy -> 8-bit PIC -> PIC microcontroller -> microcontroller -> embedded processor -> semiconductor, optimized for cost-sensitive, space-constrained applications where only a few I/O pins are needed. The PIC12HV615 integrates key differentiating features including a high-voltage shunt regulator on the VDD pin (the HV suffix), enabling direct connection to higher-voltage buses via an external Zener/resistor network without a separate LDO. It also includes an internal 8MHz oscillator (4MHz factory calibrated), 4 channels of 10-bit ADC, a comparator, and Flash program memory that supports in-circuit serial programming (ICSP). Architecturally, the PIC12HV615 uses a Harvard RISC core with separate program and data buses, allowing simultaneous instruction fetch and operand access. The wide operating range and integrated peripherals enable standalone analog and digital sensing designs without external components. The HV shunt regulator topology is distinctive: it tolerates inputs well above 5.5V (with proper external component selection), making it ideal for automotive and industrial nodes where the upstream supply is unregulated. Typical applications include LED lighting control, battery chargers, sensor signal conditioning, and automotive/industrial subsystems where board space and BOM count are critical. Compared with switching regulators + MCU combinations, the integrated HV shunt simplifies the analog front end. When designing with the PIC12HV615-I/MD, ensure the DFN-8 (MD) exposed pad is properly soldered for thermal dissipation and that the HV shunt network components are correctly sized for the target input voltage. The device is supported by Microchip's MPLAB X IDE and XC8 compiler toolchain.

PIC12HV615-I/P

PIC12HV615-I/P - 8-Bit 20MHz 1.75KB Flash MCU 8-PDIP | Microchip

The Microchip Technology PIC12HV615-I/P is an 8-bit PIC® mid-range CMOS flash microcontroller with a 20 MHz CPU and 1.75 KB (1K x 14) of program Flash memory, packaged in an 8-pin PDIP through-hole form factor. The 'HV' variant integrates an internal shunt regulator that lets the device operate directly from a high-voltage source (up to 9 V) when paired with an external Zener diode, eliminating the need for a separate 5 V regulator in many designs. The industrial temperature grade (-40 °C to +85 °C) and 6 I/O pins make it suited to compact, cost-sensitive embedded modules. The PIC12HV615 differs from the standard PIC12F615 primarily through this internal shunt regulator; otherwise the silicon (CPU core, peripherals, pinout) is shared. An 8-bit PIC microcontroller is a small, RISC-based single-chip computer built around Harvard architecture with separate program and data buses. PIC12F/HV6xx devices belong to the PIC12 family -> mid-range 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. The PIC12HV615's mid-range core executes one instruction per 200 ns at 20 MHz and uses only 35 single-word instructions, which simplifies firmware development and reduces code size. The device exposes internal 4/8 MHz precision oscillators, a configurable comparator with hysteresis, an 8-bit ADC (10-bit on later rev.), PWM, and 25 mA source/sink I/O for direct LED or transistor drive. Key features include 1.75 KB Flash program memory, 64 bytes RAM, 128 bytes EEPROM, six general-purpose I/O pins, an internal 4 MHz or 8 MHz oscillator (selectable), 20 MHz max external clock, on-chip comparator and ADC, and an internal shunt regulator for high-voltage operation. Two hardware PWM channels support simple motor or LED-dimming tasks without additional peripherals. From an architecture standpoint the PIC12HV615 uses a 14-bit instruction word mid-range core, hardware stack with eight levels, and NanoWatt power management with multiple sleep modes. The internal shunt regulator replaces the conventional VDD pin, allowing direct connection to higher-voltage rails via an external series resistor and Zener reference. Code protection follows Microchip's standard low-pin-count security scheme and is protected by U.S. Patent No. 5,847,450. Typical applications include LED lighting controllers, small appliance control, battery chargers, fan/thermostat controllers, and hobby/educational embedded boards. The internal shunt regulator makes it especially attractive in mains-derived or battery-stack designs where a low-cost 5 V rail is otherwise required. When designing with the PIC12HV615-I/P, place a 1 µF decoupling capacitor directly on the VDD/VSS pins and configure the HV regulator with an appropriate external Zener and series resistor per the datasheet typical application circuit to avoid exceeding the shunt regulator's dissipation limit.

The "HV" prefix denotes an integrated shunt voltage regulator, a niche feature that lets the chip self-regulate from a wide input range while the 8-pin DFN package keeps the solution footprint minimal. Key features include six general-purpose I/O pins, four 10-bit ADC channels, two 8-bit timers plus one 16-bit timer, an enhanced PWM/Capture/Compare module, an internal 8 MHz oscillator with PLL for 32 MHz operation, and a configurable 5-bit DAC. The HV shunt regulator accepts inputs above 2.5 V and tolerates voltage drops from unregulated supplies, which simplifies isolated or energy-harvesting designs. Debug is supported through the ICSP interface using Microchip's MPLAB® PICkit™ 5 in-circuit debugger. Typical applications include LED lighting controllers, sensor signal conditioning, battery chargers, and low-cost consumer appliance controls where board space is constrained. The DFN exposed-pad package enables efficient heat dissipation for the HV regulator while maintaining a 3 x 3 mm footprint suitable for hand-held and IoT-style enclosures. When selecting this part, ensure the application's input impedance allows the HV shunt regulator to source sufficient bias current (typically 5 mA minimum) - otherwise the optional PIC12F615 (without HV) is the lower-cost alternative.

A microcontroller (MCU) is a single-chip computer containing a processor core, non-volatile program memory, working RAM, and configurable peripherals. The PIC12HV615 belongs to the 8-bit family of microcontrollers, itself a sub-class of embedded microcontrollers, which are the smallest and most power-efficient members of the broader MCU category in the semiconductor hierarchy. 8-bit PIC MCUs use a Harvard architecture with separate program and data buses and an instruction set tuned for deterministic single-cycle execution at low clock rates. Key features of this part include a 10-bit, 4-channel Analog-to-Digital Converter (ADC), six general-purpose I/O pins, an 8-bit timer with 1:2/1:1/1:4 prescaler, a 16-bit timer/counter, one Enhanced Capture/Compare/PWM (ECCP) module, an on-chip voltage reference, and an internal 4 MHz/8 MHz oscillator selectable by configuration bits. The device draws roughly 230 µA active at 4 MHz / 2.0 V and supports industrial temperature range operation from -40 °C to +85 °C. The shunt regulator topology makes the PIC12HV615 well suited to products powered from rectified mains or 12 V rails where dropping an external linear regulator lowers BOM cost. The PIC12HV615 sits at the low end of Microchip's enhanced mid-range 8-bit line, occupying a position between baseline PIC10/12F parts and larger 14-/20-pin mid-range MCUs. Its 14-bit wide instruction word and 35-instruction RISC ISA deliver deterministic 200 ns instruction execution at 20 MHz.

Typical applications include battery charging controllers (where the shunt regulator accepts a high-voltage DC bus directly), LED drivers and signage dimming controllers, capacitive-touch front panels, low-end fan/thermostat control, simple appliance user-interface boards, and inline sensor signal conditioning modules. The 8-pin SOIC footprint also makes it a popular choice for retrofits into legacy 8-bit sockets where board space is constrained. When designing with this device, observe VDD decoupling requirements: a 0.1 µF ceramic bypass placed within 5 mm of the VDD pin and, where the shunt regulator is used, a series resistor sized so that the minimum operating current keeps the internal regulator in regulation across all load conditions.

The PIC12HV752-E/MF is well suited to LED lighting controllers, DC-DC peak current-mode power supplies, battery chargers, fan/thermostat controllers, and any application where a small MCU drives an analog feedback loop without external analog components. Its internal HV shunt regulator allows the part to power itself from a wide DC bus (typical application circuits demonstrate 12 V to 24 V operation), simplifying isolated or off-line designs. A standard external 5.1 V shunt reference replaces a separate regulator IC, reducing BOM count and PCB area in cost-driven products. When laying out the 8-DFN package, dedicate the exposed thermal pad to a contiguous ground copper pour with at least 6 thermal vias to the inner ground plane to keep junction temperature under the 150 C maximum during continuous switching. Use a 0.1 uF decoupling capacitor within 5 mm of the VDD pin.

The PIC12HV752 uses an enhanced Mid-Range 8-bit RISC core with a 14-bit instruction word, a hardware stack, and direct/indirect addressing modes. Its internal oscillator calibrates to within +/-1 percent across voltage and temperature, eliminating external resonator components in cost-sensitive designs. Brown-out reset, power-on reset, watchdog timer, and code protection provide fault tolerance for unattended installations. Typical applications include solar-powered sensor nodes, battery chargers with MPPT control, LED drivers, low-cost motor control, and general-purpose 8-bit embedded control. The HV shunt regulator simplifies designs that harvest energy from photovoltaic cells or thermoelectric generators where input voltage may be unstable. When designing with this device, place a 0.1 microfarad decoupling capacitor as close as possible to the VDD pin and ensure the MCLR/VPP shunt path has adequate impedance to limit current to the datasheet-specified range. ICSP programming requires a dedicated programmer such as PICkit 3 or MPLAB SNAP.

PIC12HV752-I/SN - 8-bit MCU, 1.75KB Flash, 8MHz Int Osc | Microchip

The Microchip Technology PIC12HV752-I/SN is an 8-bit flash-based CMOS microcontroller from the PIC12 family, featuring 1.75KB (1K x 14) of Flash program memory, 64 bytes of RAM, and 6 I/O pins in an 8-pin SOIC package. It integrates a 20 MHz internal oscillator, 5 MIPS CPU performance, and an internal shunt regulator that allows direct operation from a 2V to user-defined maximum supply. This part is the high-voltage variant of the PIC12F752 with built-in 5.1V shunt regulator. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash, RAM, EEPROM), and programmable peripherals on one silicon die. The PIC12HV752 belongs to the PIC microcontroller family (Microchip's 8-bit RISC architecture), which sits within the broader category of embedded microcontrollers -> microcontrollers -> integrated circuits -> semiconductors. PIC MCUs use a Harvard architecture with separate program and data buses, executing instructions in a single cycle for predictable real-time timing. Key features include 5 MIPS throughput at 20 MHz, 6-channel 10-bit ADC with 12-bit result via oversampling, 2 op amps, a comparator, 2 8-bit timers, 1 16-bit timer, PWM module, and high-current sink/source capability. The internal shunt regulator supports operation from input voltages up to the user-defined maximum (typically 5V regulated from higher bus voltages such as 9V, 12V, or 24V), removing the need for an external regulator on the board. Technical depth: the device uses a RISC CPU with only 35 single-word instructions, an 8-level hardware stack, and two 8-bit file registers (special function and general purpose). The integrated 5.1V shunt regulator draws excess current through the input pin when VIN exceeds the regulated voltage, enabling unregulated DC bus operation common in appliance and industrial sensor designs. Internal oscillator is factory-calibrated to +/-1% typical accuracy. Typical applications include LED lighting drivers, battery chargers, smart sensors, white-goods user-interface controls, and 12V-powered signal conditioning circuits where the integrated shunt regulator eliminates a separate LDO. Design consideration: the I/O count is limited to 6 usable pins (of 8 pins total); plan pin allocation carefully and consider the PIC12F1840 (same SOIC-8 footprint) for designs needing more peripherals. This page synthesizes distributor pricing, pin-compatible alternatives, and practical design notes not found in the manufacturer datasheet, providing engineers with a one-stop engineering brief for the PIC12HV752-I/SN.

PIC12HV752T-I/MF - 8-bit MCU 1.75KB Flash 20MHz 8-DFN | Microchip

The Microchip Technology PIC12HV752T-I/MF is an 8-bit PIC® mid-range flash microcontroller in an 8-pin VDFN (3x3 mm, exposed pad) package, integrating 1.75 KB (1K x 14) of self-read/write flash program memory, 64 bytes of SRAM, an 8 MHz internal oscillator, 6 I/O pins, a 20 MHz instruction-cycle CPU (5 MIPS), and on-chip high-speed analog peripherals. What is an 8-bit PIC® microcontroller? An 8-bit MCU is a single-chip computer with an 8-bit data path, ALU, program counter, and integrated memory plus peripherals, used to sense, decide, and actuate in embedded systems. PIC® mid-range devices sit in the taxonomy: microcontroller -> 8-bit MCU -> PIC® family -> PIC12F sub-family -> mid-range core. The HV752 variant (HV = high voltage) supports a wide supply range from 2.0 V to a user-defined VDDHV limit typically regulated via an internal shunt regulator, which lets the part operate directly from unregulated busses. Key features include a 5-channel 10-bit ADC with selectable references, two high-speed analog comparators (20 ns response), one Capture-Compare-PWM (CCP) module, an enhanced PWM with dead-band control, an 8-bit DAC, an internal voltage reference, two 8-bit timers plus one 16-bit timer, and a 4x PLL for 32 MHz operation. The 'HV' shunt regulator removes the need for an external regulator in many line-powered or battery stacks. Architecturally, the device uses Microchip's enhanced mid-range 14-bit instruction set, an 8-level hardware stack, and a single-cycle internal oscillator. The 20 MHz CPU clock delivers 5 MIPS throughput, sufficient for control loops, LED dimming, and simple sensor conditioning. Self-programmable flash and an ICD interface support field firmware updates. Typical applications include LED drivers and lighting control, battery charging front-ends, energy harvesting converters, sensor signal conditioning, small appliance controls, and IoT edge nodes. The 8-DFN package suits space-constrained designs down to roughly 10 mm². When designing, note that the exposed pad must be soldered to the ground plane for thermal dissipation and electrical reference. Decoupling caps of 0.1 µF and 1 µF should be placed within 2 mm of VDD; the ADC requires a clean analog supply and AGND tie-back. Programming/debugging uses Microchip's MPLAB X with PICkit or ICD tools.
