Microchip PIC12HV615-I/SN: High-Voltage PIC MCU for Embedded Control

In the realm of embedded systems, designers often face the challenge of efficiently managing both digital logic and higher voltage analog components within a single design. The Microchip PIC12HV615-I/SN addresses this core challenge head-on, offering a unique and highly integrated solution that simplifies designs and reduces component count. This 8-bit microcontroller combines the computational power of a proven PIC® core with an on-chip high-voltage module, making it an exceptional choice for a wide range of control applications.

A defining characteristic of the PIC12HV615-I/SN is its integrated high-voltage (HV) cell. This allows the MCU to operate directly from a wide input voltage range, typically from 2V to 15V, eliminating the need for an external linear regulator in many cases. This capability is crucial for applications powered by unregulated wall adapters, batteries, or other variable power sources. Furthermore, the HV technology enables the MCU to interface directly with higher voltage components, such as LEDs, displays, or solenoids, without requiring additional level-shifting circuitry.

Beyond its high-voltage prowess, this MCU is built around a powerful 8-bit RISC CPU core operating at up to 20 MHz, providing ample performance for complex control algorithms. It features 1.75 KB of program memory and 64 bytes of RAM. The peripheral set is robust and tailored for control tasks, including:

5-channel 10-bit Analog-to-Digital Converter (ADC) for sensor data acquisition.

Two analog comparators with programmable voltage reference for monitoring critical thresholds.

A complementary output generator for controlling motor drive circuits.

An enhanced Capture, Compare, and PWM (ECCP) module for advanced pulse generation.

High-current I/O pins capable of sourcing up to 25mA, simplifying direct LED drive.

Housed in a space-saving 8-pin SOIC package, the device is designed for compact applications. Its extended temperature range (-40°C to +85°C) ensures reliable operation in industrially harsh environments. Typical applications include appliance control (e.g., coffee makers, blenders), consumer electronics, power tool control, and any system requiring robust and reliable embedded control with simplified power architecture.
