PIC16HV610-I/ML - 1.75KB Flash 8-bit MCU, 20MHz, QFN-16 | Microchip
MPN: PIC16HV610-I/ML ✓ Hoạt độngPIC16HV610-I/ML Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash/ROM), volatile working memory (RAM), and peripheral blocks such as timers, ADCs, comparators, and communication interfaces on one die. Within the embedded hierarchy, this part belongs to the 8-bit MCU class (microcontroller -> MCU -> microcontroller IC -> integrated circuit -> semiconductor). PIC16 devices target low-pin-count, low-cost embedded control tasks such as appliance timers, LED drivers, sensor conditioning, and simple user-interface firmware.
Key features include 11 I/O pins with interrupt-on-change capability, a 10-bit ADC with up to 8 input channels, two analog comparators with programmable references, an Enhanced Capture/Compare/PWM (ECCP) module, and an internal 8 MHz oscillator. The integrated high-voltage shunt regulator (HV) accepts VIN from 2 V up to 15 V, allowing direct bus connection in 12 V systems. The device supports in-circuit serial programming (ICSP) via two pins and operates across -40 °C to +85 °C industrial temperature range.
The PIC16HV610 uses a 14-bit wide instruction set with a modified Harvard architecture, where program and data buses are separated for predictable single-cycle execution of most instructions. The HV shunt regulator and wide VIN tolerance remove the need for an external LDO in 12 V battery or industrial bus systems, simplifying BOM and reducing board area.
Typical applications include LED lighting controllers, battery chargers, appliance timers, smoke detectors, simple sensor interfaces, and 12 V industrial sensor nodes. The 2 V minimum supply voltage also enables direct use with two-cell battery packs.
When designing with this MCU, allocate at least one ICSP clock/data pair (RB6/RB7) for in-circuit programming and verify the exposed thermal pad is soldered to a sufficient copper pour for thermal dissipation under sustained peripheral activity. The 72-byte RAM constrains stack depth and large arrays, so prefer small state machines over recursive algorithms.

Ứng dụng tiêu biểu
PIC16HV610-I/ML phù hợp cho 6 Áp dụngs: 12 V LED Lighting Controllers, Battery Chargers and Power Banks, Appliance Timers and User Interfaces, Industrial Sensor Nodes, Smoke and Carbon Monoxide Detectors, Hobby and Education Development Platforms.
12 V LED Lighting Controllers
The PIC16HV610-I/ML's integrated 15 V HV shunt regulator makes it ideal for direct 12 V bus-powered LED driver controllers. The 10-bit ADC measures ambient light via an external LDR or photodiode for closed-loop dimming, while the ECCP module generates PWM dimming signals up to 20 kHz without flicker. Unlike an LDO-based design, the shunt regulator topology maintains clean logic voltage during LED inrush transients, simplifying the analog front-end. Pair this MCU with a discrete MOSFET driver and current-sense resistor for a 4-channel architectural LED strip controller. The 11 I/O pins accommodate 4 PWM channels plus I2C temperature sensing and a status LED.

Battery Chargers and Power Banks
Wide 2-15 V supply tolerance lets the PIC16HV610-I/ML connect directly to 12 V sealed lead-acid or multi-cell Li-ion packs without external regulation. The 10-bit ADC monitors battery voltage and charge current through external sense resistors, while the two analog comparators implement over-voltage and over-current protection hardware interlocks. The ECCP module drives a synchronous buck or flyback converter at up to 20 kHz with programmable dead-band control. Battery-management firmware fits in 1.75 KB Flash when written in efficient PIC assembly or optimized C. This architecture is well-suited for solar charge controllers, e-bike battery packs, and 12V portable tool chargers.

Appliance Timers and User Interfaces
The PIC16HV610-I/ML is widely deployed in washing-machine timers, dishwasher controllers, microwave oven interfaces, and HVAC zone controllers where 12 V supply rails already exist. Eleven I/O pins drive multiplexed 7-segment or matrix keypads, while the 16-bit timer provides precise countdown with interrupt-driven state machines. The internal 8 MHz oscillator eliminates one external component, reducing BOM cost below 30 cents in volume. Industrial temperature grade (-40 °C to +85 °C) covers garage, kitchen, and laundry-room environments where ambient temperatures fluctuate widely.

Industrial Sensor Nodes
12 V industrial sensor nodes for factory automation, building management, and HVAC monitoring benefit from the PIC16HV610-I/ML's direct-bus operation without an external LDO. The 10-bit ADC reads 4-20 mA current-loop or 0-10 V analog sensor signals after signal conditioning, while the 2 analog comparators detect threshold crossings for fast digital interrupts. RS-485 or CAN networking can be implemented in firmware using the ECCP and timer peripherals with an external transceiver. The QFN-16 package fits on small sensor PCBs where board area is constrained, and the exposed thermal pad provides adequate heat spreading for -40 to +85 °C operation.

Smoke and Carbon Monoxide Detectors
Battery-powered smoke detectors using a 9 V battery benefit from the PIC16HV610-I/ML's 2 V minimum VDD, which allows operation deep into battery discharge curves. The 1.75 KB Flash holds detection algorithms, self-test routines, and low-battery warning logic. The 16-bit timer drives piezo buzzer alarm patterns while the ADC reads the ionization chamber or photoelectric sensor. Ultra-low-power sleep modes (achieved in firmware by clocking down the oscillator) extend battery life to 5-10 years. The wide temperature range supports installation in attics, garages, and basements where temperatures swing widely.

Hobby and Education Development Platforms
The PIC16HV610-I/ML is an excellent teaching platform for embedded systems courses due to its simple 8-bit architecture, free MPLAB X IDE, and broad academic support. Students learn timer configuration, ADC sampling, and PWM generation within a 1.75 KB Flash constraint that encourages efficient coding practices. The ICSP interface supports PICkit 3/4 programmers that are inexpensive and widely available in university labs. The QFN-16 package, while challenging for hand-soldering, can be adapted to a breakout board for breadboard experimentation.

Ghi chú thiết kế
The integrated HV shunt regulator requires an external series resistor (typically 1 kOhm to 10 kOhm depending on supply voltage) between the raw supply and the HV pin to limit the shunt current. Per Microchip PIC16F610/16HV610 datasheet, the HV pin sinks excess voltage as heat; at 15 V supply and 5 mA load, the regulator dissipates up to 50 mW. Add a 100 nF decoupling capacitor close to the VDD pin and a 10 uF bulk capacitor on the HV input rail to suppress supply transients. Estimated: at 12 V VBUS and 10 kOhm series resistor, the steady HV current is approximately 1.2 mA - reduce resistor value if the application draws more.
The QFN-16 package has an exposed thermal pad on the underside that MUST be soldered to a copper pour of at least 25 mm² on the PCB for rated thermal performance. Without this thermal pad connection, the junction-to-ambient thermal resistance rises dramatically and the device may overheat at +85 °C ambient when peripherals are active continuously. Per Microchip QFN soldering guidelines, use a solder paste stencil with apertures for both the perimeter pins and a central pad array. For prototype work, a hot-air rework station with bottom-side preheat is recommended to reflow the thermal pad properly.
Reserve pins RC4 and RC5 for ICSP (In-Circuit Serial Programming) - they double as SDA/SCL and ICSPDAT/ICSPCLK. Do not place external pull-up resistors stronger than 10 kOhm on these pins because the PICkit programmer drives them actively during programming. Add a 4.7 kOhm to 10 kOhm pull-up to VDD if I2C peripherals are connected, and place a test-point or header footprint to allow programming access without disconnecting the rest of the circuit. Keep analog traces (RA0-RA5, RC0-RC3) short and away from PWM switching nodes to minimize ADC sampling noise.
Do not connect the MCLR/RA3 pin directly to VDD without a 10 kOhm pull-up resistor - the device cannot enter programming mode without a proper MCLR circuit. The internal oscillator calibration is factory-set but can drift up to ±2% across temperature; for UART or timing-critical applications, use the 16-bit timer with an external 32.768 kHz crystal or calibrate the internal oscillator in firmware. The 72-byte RAM is shared with the stack; recursive function calls deeper than 4-5 levels will overflow into the data section. Per the PIC16F610/16HV610 datasheet errata, some early silicon revisions have ADC channel-switching glitches - read the latest errata document before finalizing firmware.
