Microchip PIC16F1788-I/ML: A Comprehensive Technical Overview
The Microchip PIC16F1788-I/ML stands as a prominent member of the enhanced mid-range PIC16F family, engineered to deliver a powerful blend of analog integration, digital control, and flexible peripherals in a compact form factor. This 8-bit microcontroller (MCU) is designed for a vast array of applications, including industrial control, automotive subsystems, consumer electronics, and sophisticated embedded systems requiring precise analog signal management.
Housed in a 28-pin QFN (5x5mm) package, the PIC16F1788-I/ML is built on Microchip's robust enhanced mid-range core with a 16-level deep hardware stack and 49 instructions. Operating at a maximum frequency of 32 MHz, it achieves a performance level of 8 MIPS, providing ample processing power for complex control algorithms.
A defining characteristic of this MCU is its exceptional analog peripheral set, making it a premier choice for analog-intensive designs. It features a high-resolution Capture/Compare/PWM (CCP) module with Enhanced PWM capabilities, crucial for advanced motor control and power conversion applications. Furthermore, it integrates two operational amplifiers (Op Amps), a 5-bit digital-to-analog converter (DAC), and a 8-channel 10-bit Analog-to-Digital Converter (ADC) with a dedicated internal oscillator for accurate timing-independent conversions.
The digital capabilities are equally impressive. It includes two configurable logic cells (CLC) and a numerically controlled oscillator (NCO), allowing for the creation of custom logic functions directly in hardware, thereby offloading the CPU and reducing system complexity. Communication is facilitated through multiple serial interfaces: EUSART (UART), SPI, and I2C, ensuring seamless connectivity with a wide range of sensors, actuators, and other peripheral devices.
Memory resources comprise 7 KB of self-read/write Flash program memory and 512 bytes of RAM, providing sufficient space for application code and data handling. The MCU operates over an extensive voltage range of 2.3V to 5.5V and is specified for the industrial temperature range (-40°C to +85°C), guaranteeing reliability in harsh environments.
ICGOODFIND: The PIC16F1788-I/ML is a highly integrated and versatile 8-bit microcontroller. Its standout features are the rich suite of on-chip analog peripherals—including Op Amps, a DAC, and a high-resolution ADC—coupled with programmable digital hardware like CLC and NCO. This combination makes it an ideal, cost-effective single-chip solution for designing advanced embedded control systems that demand precise analog signal conditioning and efficient digital processing without requiring external components.
