Microchip PIC16LF1828-I/SS 8-Bit Microcontroller Overview and Application Guide
The Microchip PIC16LF1828-I/SS is a versatile and highly integrated 8-bit microcontroller (MCU) from Microchip Technology's enhanced mid-range PIC16F family. Housed in a 20-pin SSOP (Shrink Small Outline Package), this device is engineered for low-power operation and robust performance in a wide array of embedded control applications. Its combination of advanced peripherals, nanoWatt XLP technology, and a compact form factor makes it an ideal solution for space-constrained and battery-powered designs.
Core Architecture and Key Features
At its heart, the PIC16LF1828 is built upon an enhanced Harvard architecture core with a 32-level deep hardware stack and a 16-bit wide instruction set. It operates at a maximum frequency of 32 MHz, delivering 16 MIPS of performance. A standout feature is its extremely low power consumption, enabled by nanoWatt XLP technology, which allows it to operate in sleep modes with currents as low as 20 nA, making it perfect for applications requiring long battery life.
The MCU is equipped with 14 KB of self-read/write Flash program memory and 1024 bytes of RAM. It also features 256 bytes of high-endurance EEPROM data memory for storing critical data without power. For analog capabilities, it integrates a 10-bit Analog-to-Digital Converter (ADC) with up to 12 channels and two comparators. Communication is facilitated by multiple serial modules, including EUSART (for UART), I2C, and SPI, providing flexible connectivity options to sensors, displays, and other peripherals.
Enhanced Peripherals for Advanced Control
The PIC16LF1828 boasts several sophisticated peripherals that reduce external component count and system cost. It includes a Complementary Waveform Generator (CWG) module, which is essential for controlling half-bridge and full-bridge drivers in motor control and power conversion applications. The MCU also features a dedicated 5-bit Digital-to-Analog Converter (DAC) and a Hardware Limit Timer (HLT) for enhanced control precision.
Furthermore, it integrates a mTouch capacitive sensing module, allowing designers to easily implement robust touch interfaces without external components. This is particularly valuable for modern consumer appliances and human-machine interfaces (HMI).
