Overview

MA160014 from Microchip Technology is a PIC18F26K22 28-pin high-performance, eXtreme Low-Power (XLP) 8-bit microcontroller featuring 64 KB Flash program memory, 3896 bytes RAM, 1024 bytes data EEPROM, 16 MIPS operation at DC–64 MHz, and integrated 10-bit ADC with up to 19 analog inputs. It serves as a system controller in battery-powered sensor nodes requiring precise timing, analog sensing, and low-power PWM motor control.

For engineers reviewing the MA160014 datasheet, MA160014 pinout, MA160014 application, or MA160014 equivalent, key selection criteria include its 20 nA Sleep current, dual EUSART with LIN/RS-232 support, four enhanced CCP modules for half/full-bridge PWM, 28-pin SOIC/QFN package compatibility, and factory-calibrated ±1% internal oscillator enabling crystal-free operation.

Technical Context

The MA160014 implements a RISC CPU with 31-level hardware stack, priority-based interrupts, and optional extended instruction set optimized for C re-entrant code. Its oscillator architecture integrates a precision 16 MHz HFINTOSC (±1% factory-calibrated), 31 kHz LFINTOSC, and 4× PLL-enabling full-speed 64 MHz operation without external components.

Power management includes XLP modes: 20 nA Sleep, 300 nA WDT, and peripheral module disable. Analog subsystem comprises a 10-bit ADC with auto-acquisition, two rail-to-rail comparators, 5-bit DAC with FVR outputs (1.024V/2.048V/4.096V), and CTMU for capacitive touch sensing.

FAQ

What is the maximum operating frequency of the MA160014 and how is it achieved?

The MA160014 achieves a maximum operating frequency of 64 MHz using its internal 16 MHz HFINTOSC combined with the integrated 4× Phase-Lock Loop (PLL). This configuration requires no external crystal or clock source, reducing BOM cost and board space. The internal oscillator is factory-calibrated to ±1% accuracy, ensuring reliable high-speed operation across voltage and temperature ranges. All timing-critical peripherals-including ECCP, EUSART, and ADC-scale synchronously with this 64 MHz system clock.

Does the MA160014 support crystal-free RS-232 communication?

Yes, the MA160014 supports crystal-free RS-232 communication via its EUSART modules. When configured to use the internal 16 MHz oscillator with PLL enabled, the EUSART's 16-bit baud rate generator achieves sufficient resolution for standard RS-232 rates (e.g., 9600, 19200, 115200 bps) with <2% error. This eliminates the need for an external crystal while maintaining reliable UART communication in portable and cost-sensitive designs.

How many analog input channels does the MA160014 ADC support, and what reference options are available?

The MA160014 ADC supports up to 19 external analog input channels (AN0–AN19), plus internal channels for Fixed Voltage Reference (FVR) and DAC output. Reference options include external VREF+ and VREF− pins, internal FVR outputs (1.024 V, 2.048 V, 4.096 V), and the DAC output itself. This flexibility allows ratiometric measurements, precision sensor interfacing, and self-calibration routines without external reference ICs.

What PWM capabilities does the MA160014 provide for motor control applications?

The MA160014 integrates four Enhanced CCP (ECCP) modules optimized for motor control. Each supports configurable polarity, programmable dead time (1–1024 × Tosc), auto-shutdown on fault signals (e.g., FLT0), and auto-restart. Two modules operate in half-bridge mode and two in full-bridge mode, enabling three-phase BLDC or dual H-bridge DC motor control. PWM steering allows dynamic routing of outputs to specific pins, simplifying PCB layout for complex drive topologies.

Is the MA160014 compatible with Microchip's MPLAB® X IDE and debug tools?

Yes, the MA160014 is fully supported by Microchip's MPLAB® X IDE v5.45+ and MPLAB® ICD 4 debugger. Its RB6/PGC and RB7/PGD pins implement standard In-Circuit Serial Programming™ (ICSP™) and In-Circuit Debug (ICD) protocols using single-supply 3V programming. Real-time variable watch, hardware breakpoints, and live register inspection are available. The device also supports bootloader development via its self-programmable Flash memory and protected Boot Block.
