Microchip PIC16LF1789T-I/ML: Low-Power 8-Bit Microcontroller for Embedded Control Applications
The Microchip PIC16LF1789T-I/ML is a highly integrated, 8-bit microcontroller designed for demanding embedded control applications where low power consumption, robust peripheral integration, and cost-effectiveness are paramount. As part of Microchip's extensive PIC16F family, this device leverages a proven, high-performance RISC architecture to deliver a compelling solution for a wide array of industrial, consumer, and automotive systems.
At the core of this microcontroller is an enhanced mid-range 8-bit PIC® CPU core, capable of operating at up to 32 MHz. This provides ample processing power for complex control algorithms and real-time system management. A key advantage of the PIC16LF1789T-I/ML is its extremely low power consumption, a hallmark of the "LF" variant. Featuring nanoWatt XLP technology, it is engineered for applications that demand extended battery life or are powered by energy harvesting sources. This includes multiple low-power sleep modes and rapid wake-up times, enabling designers to create products that spend most of their life in a quiescent state, consuming minimal current.
The device stands out due to its exceptional set of integrated peripherals, which significantly reduce the need for external components, thereby lowering overall system cost and complexity. Its analog capabilities are particularly noteworthy. It includes a 12-bit Analog-to-Digital Converter (ADC) with Computation (ADC²) module, which can perform data processing autonomously without CPU intervention, further saving power. For precision sensing and control, it is equipped with 5-bit and 12-bit Digital-to-Analog Converters (DACs), operational amplifiers (op amps), and comparators.
For control applications, it integrates high-performance PWM modules, complementary waveform generators (CWG), and a dedicated 16-bit Capture/Compare/PWM (CCP) module. Communication is facilitated through multiple serial interfaces, including EUSART (for LIN support), I²C, and SPI, ensuring easy connectivity to sensors, actuators, and other system components.
Housed in a compact 28-pin QFN (ML) package, the PIC16LF1789T-I/ML is ideal for space-constrained designs. Its combination of low-power operation, rich analog and digital peripherals, and a resilient design makes it perfectly suited for applications such as sensor nodes, motor control systems, power management, lighting control, and various Internet of Things (IoT) endpoints.
ICGOOODFIND: The PIC16LF1789T-I/ML is a powerhouse of integration, masterfully balancing computational performance with ultra-low power consumption. Its rich suite of on-chip analog and control peripherals makes it an outstanding single-chip solution for sophisticated embedded control systems, simplifying design and accelerating time-to-market.
