PIC16HV753-I/P - 8-Bit MCU, 3.5KB Flash, HV Shunt Reg | Microchip
MPN: PIC16HV753-I/P ✓ Hoạt độngPIC16HV753-I/P Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory and peripherals on one die. The PIC16 family belongs to the RISC (Reduced Instruction Set Computer) class of 8-bit microcontrollers; in the broader product taxonomy, MCUs sit inside embedded microcontrollers, which sit inside microprocessors, which sit inside semiconductor ICs. The 'HV' in the part number indicates the high-voltage shunt-regulator feature, which in the broader power management hierarchy corresponds to a linear regulator function co-integrated with the digital logic.
Key differentiating features include nanoWatt XLP technology for ultra-low power consumption, 9-bit DAC with internal bandgap reference, 4-channel 10-bit ADC, enhanced Capture/Compare/PWM (ECCP) module, and integrated shunt regulator for direct high-voltage operation. The 14-pin PDIP package offers ease of prototyping and breadboarding compared to surface-mount variants.
The PIC16HV753's architecture combines a 14-bit instruction word with a Harvard bus, providing deterministic interrupt response and compact code density. The 9-bit DAC can be operated in 5-bit, 7-bit or 9-bit resolution modes and supports ramp generation for closed-loop control. Internal peripherals include up to 11 I/O pins, two 8-bit timers, one 16-bit timer, and an Enhanced Universal Synchronous/Asynchronous Receiver/Transmitter (EUSART) for serial communication.
Typical applications include LED drivers and lighting control, battery charging management, sensor signal conditioning, low-power remote sensors, and industrial control loops. The internal shunt regulator enables direct 12V or 24V industrial-rail operation in a single chip.
When designing with this part, note that the shunt regulator dissipates excess voltage as heat; ensure adequate PCB copper or thermal relief at the VDD/REG pin. The PDIP package supports easy in-circuit programming via the ICSP interface but consumes more board area than SOIC-14 or QFN-16 alternatives.

High-Voltage LED Lighting Driver
The PIC16HV753-I/P fits high-voltage LED lighting drivers because its integrated shunt regulator accepts 12 V or 24 V industrial rails directly, eliminating the external linear regulator. The 9-bit DAC provides smooth PWM-like dimming control, while the Enhanced CCP module generates the switching waveform at up to 20 MHz core speed.

The PIC16HV753-I/P is well suited for industrial 4-20 mA loop-powered sensor conditioning because the integrated HV shunt regulator drops 24 V loop voltage to a regulated 5 V VDD, simplifying isolation design. The 10-bit ADC reads the sensor with 4 mV resolution at 5 V, while the 9-bit DAC provides offset nulling. According to Microchip datasheet DS40001709D, nanoWatt XLP technology keeps quiescent current below 1 uA in sleep mode, extending battery life in wireless sensor nodes.

Ghi chú thiết kế
The integrated HV shunt regulator dissipates (VIN - VDD) x ILOAD as heat. For example, at VIN = 12 V, VDD = 5 V, and 30 mA load, the regulator dissipates 210 mW. At 50 mA this rises to 350 mW. Estimated: with the 14-pin PDIP theta_JA of approximately 80 C/W (still air), junction temperature rises 28 C above ambient at 350 mW dissipation - within the 85 C industrial limit but approaching the 125 C absolute maximum at higher VIN. Add a copper pour or thermal relief to the VDD pin for sustained operation above 40 mA from 24 V rails.
Place a 100 nF ceramic bypass capacitor directly across VDD (pin 1) and VSS (pin 14) with traces shorter than 5 mm. For ICSP programming, dedicate RA0 (ICSPDAT) and RA1 (ICSPCLK) and isolate them from high-current traces. When using the internal oscillator, route RA5/OSC1 and RA4/OSC2 as GPIO to reduce EMI; otherwise keep the crystal/oscillator traces short and guarded by a ground ring.
Do not connect both VIN and an external 5 V supply to VDD simultaneously - the internal shunt regulator will fight the external supply. Either use the HV regulator with a single VIN and no external VDD, or use an external regulator and disable the HV shunt by tying VIN to VDD. The MCLR/RA3 pin has an internal weak pull-up but should be pulled to VDD with a 10 kohm resistor for production noise immunity. Configuration bits must be programmed to disable unused peripherals to minimize sleep current.
The 9-bit DAC output (DACOUT, internally generated) has approximately 5 LSBs of integral nonlinearity and is intended for slow setpoint generation, not high-fidelity audio. For analog output applications, add an external MCP6L01 op-amp buffer to drive low-impedance loads. The 10-bit ADC input impedance is highly source-impedance dependent; keep source impedance below 10 kohm for full 10-bit accuracy, otherwise use the integrated charge pump and longer acquisition time.
