Microchip PIC16F18854-E/ML 8-Bit Microcontroller Data Sheet and Technical Specifications
The Microchip PIC16F18854-E/ML is a high-performance, low-power 8-bit microcontroller built on Microchip’s enhanced mid-range core (PIC16F1xxx). With its rich set of integrated peripherals and robust feature set, this MCU is engineered for a wide range of embedded control applications in automotive, industrial, consumer, and Internet of Things (IoT) domains.
Core Architecture and Performance
At the heart of this device is an enhanced mid-range 8-bit CPU core with a 16-level deep hardware stack and 49 instructions. Operating at a maximum frequency of 32 MHz, it can achieve up to 8 MIPS (Million Instructions Per Second). The core includes a Memory Access Partition (MAP) feature, which enhances bootloader and application security by protecting specific memory regions.
Memory Configuration
The PIC16F18854 offers a substantial memory allocation for its class, featuring 14 KB of Flash program memory with self-read/write capability and 1024 bytes of SRAM. It also includes 256 bytes of high-endurance EEPROM for critical data storage that must be retained through power cycles.
Advanced Analog Peripherals
A standout feature of this microcontroller is its sophisticated analog suite. It integrates a 12-bit Analog-to-Digital Converter (ADC) with Computation (ADC2). This unique capability allows the ADC to perform analog computations (averaging, filtering, threshold comparison) in hardware without CPU intervention, drastically reducing power consumption and freeing up core processing time. Additionally, it includes a 5-bit Digital-to-Analog Converter (DAC), two comparators, and a Fixed Voltage Reference (FVR).
Specialized Timers and Control Peripherals
For timing and control applications, the device is equipped with a powerful array of peripherals:
5 Timers: Including four 8-bit timers and one 16-bit timer.
Complementary Waveform Generator (CWG): Outputs complementary signals with dead-band control for driving half-bridge and full-bridge circuits in power conversion.
Windowed Watchdog Timer (WWDT): Can be configured to only trigger on a specific time window, enhancing system reliability against code malfunctions.
Hardware Limit Timer (HLT): Provides a safety mechanism to shut down peripherals like the CWG in fault conditions.
Communication Interfaces
The PIC16F18854 supports a versatile set of serial communication protocols, ensuring easy connectivity with other system components:
EUSART (Universal Synchronous Asynchronous Receiver Transmitter): Supports RS-485, RS-232, and LIN compatibility.
MSSP (Master Synchronous Serial Port): Can be configured as either I²C or SPI interface.
MSSP (Master Synchronous Serial Port): Can be configured as either I²C or SPI interface.
Operating Characteristics and Packaging
Designed for robustness and low-power operation, the MCU operates over a wide voltage range (1.8V to 5.5V) and an industrial temperature range (-40°C to +85°C). Its low current consumption is further optimized by multiple idle and sleep modes. The PIC16F18854-E/ML is offered in a compact 28-pin QFN (5x5mm) package (ML), making it suitable for space-constrained PCB designs.
Summary by ICGOODFIND
The Microchip PIC16F18854-E/ML is a highly integrated and capable 8-bit microcontroller. Its combination of a powerful core, advanced analog peripherals like the 12-bit ADC with Computation, and dedicated control features such as the Complementary Waveform Generator make it an exceptionally strong solution for complex control tasks in power supply, motor control, and sophisticated sensing applications, all while maintaining the simplicity and cost-effectiveness of an 8-bit architecture.
