Microchip Technology PIC12HV615-E/SN

Overview

PIC12HV615-E/SN from Microchip Technology is an 8-pin, flash-based 8-bit CMOS microcontroller with integrated shunt voltage regulator, 10-bit ADC (4 channels), enhanced CCP module (PWM/compare/capture), and analog comparator. It operates from 2.0V to user-defined maximum voltage (shunt-regulated up to 5V), supports 20 MHz internal/external clocking, and delivers 260 µA typical operating current at 4 MHz/2.0V. It targets embedded sensor interface and low-voltage industrial control applications requiring on-chip regulation and mixed-signal capability.

For engineers reviewing the PIC12HV615-E/SN datasheet, PIC12HV615-E/SN pinout, PIC12HV615-E/SN application, or PIC12HV615-E/SN equivalent, key selection factors include its integrated 5V shunt regulator, 10-bit 4-channel ADC, dual PWM output with programmable dead time, 16-bit capture resolution (12.5 ns), and compatibility with In-Circuit Serial Programming via two pins.

Technical Context

The PIC12HV615-E/SN implements a RISC CPU with 35 single-cycle instructions (except branches), an 8-level hardware stack, and three addressing modes. Its oscillator system includes a factory-calibrated ±1% internal oscillator (4 MHz or 8 MHz selectable) plus external crystal/resonator or RC support on GP5/GP4.

Peripheral integration centers on mixed-signal functionality: one analog comparator with software-selectable hysteresis and programmable CVREF, Timer0 (8-bit with prescaler), enhanced Timer1 (16-bit with gate control and multiple clock sources), Timer2 (8-bit with period register), and ECCP module supporting PWM (10-bit, up to 20 kHz), compare, and capture with auto-shutdown.

FAQ

What is the maximum input voltage allowed on VDD for PIC12HV615-E/SN?

The PIC12HV615-E/SN does not have a fixed maximum VDD rating. Its shunt regulator limits the effective operating voltage to ≤5 V - voltage applied to VDD must be ≥5 V to enable regulation, but the shunt device clamps excess voltage, so input must be sized to dissipate power within the 4–50 mA shunt range. Exceeding 5 V across the shunt is prohibited per datasheet Note on page 3.

Does PIC12HV615-E/SN support In-Circuit Serial Programming (ICSP)?

Yes, PIC12HV615-E/SN supports ICSP via GP0 (ICSPDAT) and GP1 (ICSPCLK) pins. These functions are multiplexed with general I/O and analog capabilities, and require no additional hardware beyond standard ICSP circuitry. Programming voltage (VPP) is applied to GP3/MCLR during entry, and the internal shunt regulator remains active during programming if VDD is supplied externally above 5 V.

Can PIC12HV615-E/SN generate complementary PWM signals with dead time?

Yes, PIC12HV615-E/SN's Enhanced Capture/Compare/PWM (ECCP) module supports dual PWM outputs (P1A and P1B) with programmable dead time insertion. This allows safe driving of high-side/low-side MOSFET pairs in half-bridge topologies. Dead time is configured in the PWM1CON register and applies automatically during PWM transitions.

What ADC reference options are available on PIC12HV615-E/SN?

PIC12HV615-E/SN supports two ADC reference sources: VDD (default) and external voltage applied to GP1/VREF pin. The VREF pin accepts 1.2–5.0 V and overrides the internal reference. No internal bandgap or fixed-voltage reference is present - accuracy depends on stability of selected reference source.

Is the internal oscillator of PIC12HV615-E/SN factory calibrated?

Yes, the PIC12HV615-E/SN internal oscillator is factory calibrated to ±1% typical accuracy at 4 MHz and 8 MHz. Calibration values are stored in configuration memory and automatically loaded at startup. Software can select between 4 MHz and 8 MHz modes using the IRCF bits in the OSCCON register.
