PIC16HV610-I/SL 概述
What is an 8-bit microcontroller? An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash/ROM), data memory (RAM), and peripherals on one die. Within the embedded hierarchy, PIC16 MCUs sit below PIC18/PIC24 and above baseline PIC10/12 devices, balancing code density (14-bit instruction word), peripheral count, and cost for cost-sensitive control applications.
Key features include 64 bytes of RAM, 11 digital I/O pins with interrupt-on-change capability, an 8-channel 10-bit ADC, two analog comparators, a hardware timer0/timer1/timer2 set, and a built-in 5-bit DAC on the comparator reference. The integrated shunt regulator accepts input voltages from 2 V (at 8 MHz) up to 15 V (via shunt), eliminating the need for an external 5 V LDO in many mains-derived designs.
Typical applications include LED driver controllers, battery chargers, smoke and CO detectors, mains-powered sensor interfaces, and off-line appliance control. Designers favor the HV610 series for its ability to operate directly from rectified mains via a Zener/shunt arrangement, reducing BOM cost by one or two external regulators.
When designing with the PIC16HV610, choose between the SL (SOIC-14) and ML (QFN-20) packages based on board area constraints. Always place the shunt regulator's series resistor to limit current to the datasheet-specified maximum and add bulk decoupling on the regulated rail. A free MPLAB X IDE with XC8 compiler supports the device for code development and debug.

典型应用
PIC16HV610-I/SL 适用于 7 应用s: Mains-Powered LED Driver Controller, Smoke and CO Detector Control, Battery Charger Controller, Off-line Appliance Control, Industrial Sensor Interface Module, Automotive Accessory Controller, Smart Home Sensor Node.
Mains-Powered LED Driver Controller
The PIC16HV610-I/SL is purpose-built for LED driver controllers fed from rectified mains. Its internal shunt regulator accepts 2-15 V input, allowing direct connection to a current-limiting resistor from rectified mains without an external LDO. The 20 MHz CPU and 1.75 KB flash drive PWM dimming via Timer2, while the 8-channel 10-bit ADC senses LED current and temperature. The two analog comparators enable overcurrent and over-temperature shutdown. Pair with a discrete MOSFET or LED driver IC for the power stage.
推荐
Smoke and CO Detector Control
The PIC16HV610-I/SL is a popular choice for ionization-chamber smoke and electrochemical CO detectors. The internal HV shunt lets the MCU run directly from a 9 V battery with a simple series resistor, eliminating the LDO and saving BOM cost. The two analog comparators handle the ionization chamber sense amplifier and piezo horn driver, while the ADC reads battery voltage for low-battery chirp. 1.75 KB flash accommodates self-test routines and alarm-logic state machines.
推荐
Battery Charger Controller
NiMH and Li-ion charger designs benefit from the PIC16HV610-I/SL's high-voltage tolerance and integrated ADC. The internal shunt accepts 12-15 V wall-adapter output directly, charging 4-cell NiMH packs with delta-V termination sensed by the 10-bit ADC. The 5-bit DAC on the comparator reference sets precise charge-current thresholds. Industrial temperature grade and 20 MHz operation support fast-charge algorithms with thermal foldback.
推荐
Off-line Appliance Control
White-goods and small appliances use the PIC16HV610-I/SL as a low-cost control MCU powered directly from rectified mains through a Zener or shunt arrangement. The 11 I/O pins drive relays, triacs, buttons, and indicator LEDs. Hardware timers generate zero-crossing detection for triac dimming, while the ADC reads NTC thermistors for safety cut-off. The industrial temperature range handles under-cabinet and motor-compartment environments.
推荐
Industrial Sensor Interface Module
The PIC16HV610-I/SL acts as a smart front-end for 4-20 mA loop-powered or 0-10 V industrial sensors. Its wide 2-15 V input range tolerates unregulated 24 V loop supplies via the shunt regulator, while the 10-bit ADC digitizes the sensor signal and the two comparators detect out-of-range conditions. 1.75 KB flash runs linearization, calibration, and HART or Modbus framing routines for small sensor modules.
推荐
Automotive Accessory Controller
The PIC16HV610-I/SL suits 12 V automotive accessory controllers for interior lighting, seat heaters, and aftermarket modules. The internal shunt accepts 12 V battery directly without a pre-regulator. Industrial temperature grade covers cabin environments; for under-hood use, designers select the PIC16HV610-E/SL (extended temperature) variant. The 11 I/O lines drive MOSFETs, sense switches, and PWM dim cabin lights via Timer2.
推荐
Smart Home Sensor Node
Low-cost smart-home sensors use the PIC16HV610-I/SL as a battery-friendly controller in wall switches and door/window contact sensors. The internal HV shunt supports long-life 9 V or 12 V batteries, while the 20 MHz speed handles simple RF or sub-GHz protocols. The 64-byte RAM supports small sensor-fusion buffers, and the on-chip comparator detects tamper-switch events for security devices.

设计说明
Estimated: The internal HV shunt regulator dissipates (VIN - 5V) x Ishunt as heat. For a 12V supply at 5 mA shunt current, the device dissipates roughly 35 mW, well within the SOIC-14 800 mW rating. At 15V input and 10 mA shunt current, dissipation rises to 100 mW; ensure the layout provides adequate copper pour for thermal relief. Always add a 100 nF decoupling capacitor close to Vdd and a 10 uF bulk capacitor on the shunt node.
Place the shunt regulator's series resistor between the unregulated input and the Vdd pin, sized to limit current to the datasheet maximum under worst-case input voltage. Keep the ICSPDAT/ICSPCLK traces short and away from switching nodes to avoid programming and ADC noise coupling. Use a ground pour under the MCU and route analog inputs (ANx) away from digital I/O to preserve ADC accuracy.
Do not exceed the maximum Vdd of 15V or the maximum shunt current specified in the datasheet, or the internal regulator will latch up. The MCLR pin is a reset input, not a power pin; tie to Vdd through a 10 kohm resistor for normal operation. Configuration words must be programmed correctly or the MCU will not boot; use MPLAB X to set the oscillator and watchdog options.
