PIC16HV610-E/ML - 1.75KB Flash 8-bit MCU, 20MHz, High-Voltage | Microchip
MPN: PIC16HV610-E/ML ✓ Hoạt độngPIC16HV610-E/ML Tóm tắt
A high-voltage PIC microcontroller is a variant of the standard PIC16 baseline family that integrates an internal shunt regulator on the VDD pin, allowing the part to source current from a higher-voltage bus while clamping VDD to a safe logic level. This makes the PIC16HV610 part of the microcontroller -> 8-bit MCU -> PIC16 baseline -> high-voltage PIC hierarchy, sitting alongside general-purpose logic and analog peripherals for sensor and motor control. The HV610 suffix specifically refers to the internal shunt regulator block, distinguishing it from the lower-voltage PIC16F610 sibling.
Key features include 1.75 KB self-programmable Flash, 72 B SRAM, 128 B EEPROM (HV616 variant), two enhanced analog comparators with programmable on-chip reference, an internal 8 MHz oscillator, and a wide 2 V to 15 V operating range enabled by the integrated shunt regulator. The 16-pin QFN package gives a compact 4x4 mm footprint suitable for high-density designs, while the industrial-grade -40C to +125C operating range supports automotive, industrial, and appliance environments.
Technically, the PIC16HV610 uses a 14-bit instruction word RISC architecture with a hardware stack of 8 levels, single-cycle instructions except for branches, and a 20 MHz maximum clock speed from an external source or the internal 8 MHz oscillator. The integrated shunt regulator removes the need for an external LDO in 12 V or 24 V bus systems, reducing BOM cost and PCB area. NanoWatt Technology provides power-managed sleep modes for battery and energy-harvesting applications.
Typical applications include high-voltage sensor interfaces, white-good and appliance control, automotive interior modules, battery chargers, LED lighting controllers, and 12 V/24 V industrial sensor signal conditioning. The internal shunt regulator and two comparators make it especially well-suited to analog front-end tasks where the MCU must coexist on a high-voltage rail.
When designing with this part, designers should consider the shunt regulator's current limit and power dissipation: at 15 V input the shunt can dissipate up to ~0.9 W into VDD, requiring thermal management per the datasheet. The HV610 variant does not include the 10-bit ADC; choose PIC16HV616-I/ML if ADC is required.

PIC16HV610-E/ML phù hợp cho 6 Áp dụngs: High-Voltage Sensor Interface, White Goods and Appliance Control, Automotive Interior Modules, Battery Charging Controllers, LED Lighting Drivers, Industrial Sensor Signal Conditioning.
High-Voltage Sensor Interface
The PIC16HV610-E/ML is purpose-built for sensor signal chains that share a 12 V or 24 V bus with actuators, motors, or relays. Its integrated shunt regulator lets the MCU clamp its own VDD to a logic-safe level directly from the high-voltage rail, eliminating an external LDO and shrinking BOM cost. The two on-chip analog comparators with programmable internal reference can condition a 0-12 V sensor signal (e.g., thermistor divider, photodiode, current shunt) and trigger an interrupt without an external op-amp. With 1.75 KB Flash and 72 B RAM, the PIC16HV610-E/ML handles simple threshold detection, hysteresis control, and PWM feedback loops at the sensor node. Compared to a discrete MCU + LDO + comparator solution, this part reduces board area by roughly 40 percent while supporting -40C to +125C operation.

White Goods and Appliance Control
Major appliances such as washing machines, dishwashers, and HVAC controllers run on 12 V or 24 V internal rails where the PIC16HV610-E/ML can plug in directly without a regulator. The 20 MHz CPU speed and 14-bit PIC instruction set execute closed-loop control algorithms for motor triac firing, valve actuation, and pump sequencing with deterministic timing. The two comparators monitor zero-cross events on the AC mains for triac phase-angle control, while the PWM module drives solenoids and relays. Industrial-extended -40C to +125C temperature grade handles under-cabinet and outdoor-rated appliance environments. The 16-pin QFN 4x4 mm footprint fits beneath the high-voltage isolation barrier on compact control boards.

Automotive Interior Modules
Automotive body controllers, seat heaters, mirror adjusters, and ambient lighting modules often run on the vehicle's 12 V battery rail with significant voltage transients. The PIC16HV610-E/ML's 2-15 V operating range and integrated shunt regulator tolerate cranking transients and load-dump events without an external TVS-protected LDO chain. The MCU's 11 GPIO pins drive multiple LED strings via PWM, read NTC thermistors for seat temperature, and scan switch matrices for door and seat-occupancy signals. AEC-Q100 qualified siblings exist for OEM designs, while the industrial-extended -40C to +125C PIC16HV610-E/ML suits aftermarket and Tier-2 modules. Compared to a 5 V MCU with external regulator, this part reduces standby quiescent current and BOM count.

Battery Charging Controllers
Lead-acid, Li-ion, and NiMH chargers typically operate from 12 V or 24 V adapters and need a small MCU to monitor cell voltage, temperature, and charge current. The PIC16HV610-E/ML's shunt regulator allows it to sit directly on the 12 V supply rail, with the two analog comparators implementing hardware-based over-voltage and over-current protection independent of firmware execution. The PWM module drives the buck converter MOSFET or linear pass element, while the 1.75 KB Flash holds state-machine code for CC/CV charge profiles. Industrial-extended temperature grade supports under-hood and outdoor charger enclosures. NanoWatt sleep modes drop quiescent current below 100 nA for maintenance charging on standby.

LED Lighting Drivers
Architectural, sign, and emergency LED fixtures often share a 12 V or 24 V constant-voltage bus and require per-string current regulation and dimming control. The PIC16HV610-E/ML accepts that bus directly via its shunt regulator and uses PWM plus the 8-bit timer to generate constant-current drive signals for external MOSFETs or LED driver ICs. The two comparators monitor LED string voltage for open-LED and short-LED fault detection, triggering protective shutdown within microseconds. The 20 MHz CPU executes smooth logarithmic dimming curves and DALI or 0-10 V interface decoding. Compared to a 5 V MCU plus LDO, this part removes one stage of power conversion and improves overall driver efficiency by 1-2 percent.

Industrial Sensor Signal Conditioning
Industrial PLCs, 4-20 mA loops, and process-control transducers operate on 24 V rails where the PIC16HV610-E/ML's high-voltage shunt regulator is a natural fit. The MCU's two comparators with programmable internal reference perform window-comparator signal conditioning on transducer outputs, generating interrupts when process variables cross setpoints. The 1.75 KB Flash holds linearization tables for thermocouples and RTDs, while the 72 B RAM is sufficient for moving-average filtering. The -40C to +125C industrial-extended grade handles factory-floor temperature ranges. Compared to analog-only conditioning circuits, this part enables digital calibration and diagnostics over the same I/O pins.

Ghi chú thiết kế
The PIC16HV610-E/ML's shunt regulator clamps VDD to a logic-safe voltage by shunting current to ground. Per the datasheet, the shunt can dissipate up to ~0.9 W at VIN=15 V and IOUT_VDD=100 mA. Always select the VDD current-limit resistor per the datasheet equation R_S = (VIN - VDD) / I_SHUNT, and ensure total system VDD current (including I/O sourcing) stays below the shunt's rated current. Insufficient headroom or excessive IOUT will trigger the shunt's thermal limit and reset the part.
The QFN-16 (ML) package has an exposed thermal pad (EPAD) on pin 16 that must be soldered to the ground plane for electrical reference and thermal dissipation. Per Microchip layout guidelines, use an array of thermal vias under the EPAD (typically 4-9 vias at 0.3 mm drill) to conduct heat into inner ground planes. Place the external shunt current-limit resistor within 5 mm of the VDD pin to minimize parasitic inductance, and keep high-current switching traces away from the OSC1/OSC2 pins.
Do not assume the PIC16HV610-E/ML includes an ADC - it does not. The ADC is only present on the PIC16HV616 variant. Attempting to set ADCON0 bits on PIC16HV610 will produce undefined behavior. Also note that the extended -40C to +125C grade is required for under-hood or outdoor deployments; the I-grade -40C to +85C variant will reset or malfunction above 85C. Finally, MCLR must be pulled high through a 10 kohm resistor for normal operation; leaving MCLR floating prevents the part from exiting reset.
