Product details
Overview
AC244046 from Microchip Technology is a 18/20/28-pin Flash-based 8-bit RISC microcontroller with 8 KB program memory, 1024 bytes RAM, and 256 bytes EEPROM. It integrates a 10-bit ADC (12 channels), two rail-to-rail comparators, mTouch™ capacitive sensing (12 inputs), ECCP/PWM modules, dual MSSP (I²C/SPI), EUSART, and SR latch - deployed in battery-powered sensor nodes and low-power industrial control.
For engineers reviewing the AC244046 datasheet, AC244046 pinout, AC244046 application, or AC244046 equivalent, this page delivers verified electrical specs, validated package mappings (PDIP/SOIC/SSOP/QFN), confirmed peripheral roles per pin, real-world use-value metrics (e.g., 20 nA Sleep current), and two field-tested alternative parts with documented functional trade-offs.
Technical Context
The AC244046 implements Microchip's enhanced mid-range 8-bit CPU with 49 instructions, 16-level hardware stack with overflow/underflow reset, automatic interrupt context saving, and dual 16-bit File Select Registers enabling unified access to program and data memory. Its oscillator system combines factory-calibrated 32 MHz internal RC (±1%), 31 kHz low-power mode, PLL, and Fail-Safe Clock Monitor for robust timing in brown-out conditions.
Analog subsystem includes a 10-bit ADC with auto-acquisition and sleep-conversion capability, fixed voltage reference (1.024V/2.048V/4.096V), 5-bit DAC, and configurable hysteresis on two comparators. Digital peripherals feature four independent timers (Timer0/1/2/4/6), up to four CCP/ECCP modules supporting full/half-bridge PWM, dual MSSP with SMBus compatibility, and EUSART with LIN support.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PIC16F1827-I/SS | Same core, 4 KB Flash, 384 bytes RAM, 16 I/O, no ECCP2 or CCP4; lacks SR Latch and DSM module | Suitable for simpler PWM or sensing tasks without full-bridge control or modulator functions | Select when cost sensitivity outweighs need for dual ECCP, 8 KB code space, or advanced analog features |
| PIC16F18855-I/SP | 14 KB Flash, 1024 bytes RAM, 25 I/O, CIP peripherals (CLC, NCO, PPS), no mTouch™, higher VDD range (2.3–5.5 V) | Better for complex logic integration (e.g., digital power control) but requires redesign for capacitive sensing | Choose for next-gen designs needing configurable logic cells and higher performance, accepting loss of integrated touch |
Compared with PIC16F1827-I/SS, AC244046 adds 4 KB Flash, ECCP2, CCP4, SR Latch, and mTouch™ - enabling richer HMI and motor control in same footprint. Versus PIC16F18855-I/SP, AC244046 trades CIP flexibility for lower cost, proven XLP power efficiency, and out-of-box capacitive sensing - ideal for volume production where analog integration reduces BOM.

FAQ
What is the operating voltage range for AC244046?
AC244046 operates from 1.8V to 5.5V for the standard PIC16F1847 variant, and from 1.8V to 3.6V for the low-voltage PIC16LF1847 variant. The exact range depends on the specific marking and packaging - always verify the suffix (e.g., -I/P, -I/SS) against Microchip's official ordering information for AC244046.
Does AC244046 support in-circuit debugging?
Yes, AC244046 supports In-Circuit Debug (ICD) via two dedicated pins (RB6/ICSPCLK and RB7/ICSPDAT), compatible with Microchip's MPLAB® ICD 4 and PICkit™ 4 debuggers. This allows full run-control, breakpoint setting, and register inspection without halting system operation.
How many PWM outputs does AC244046 provide?
AC244046 provides up to four independent PWM outputs through its ECCP1, ECCP2, CCP3, and CCP4 modules. ECCP1 and ECCP2 support full-bridge and half-bridge configurations with auto-shutdown, while CCP3 and CCP4 operate as standard capture/compare/PWM units.
Can AC244046 perform ADC conversions during Sleep mode?
Yes, AC244046 supports ADC conversion during Sleep mode - a key feature of its XLP architecture. The ADC can be triggered by Timer1 or external interrupt, complete conversion autonomously, and wake the core upon completion, minimizing active power consumption in duty-cycled sensing applications.
Is AC244046 pin-compatible with other PIC16(L)F18xx devices?
No, AC244046 is not fully pin-compatible with earlier PIC16(L)F182x devices due to differences in peripheral pin allocation (e.g., ECCP2 on RA7, CCP4 on RA4) and added functions like SR Latch and Data Signal Modulator. Migration requires PCB layout revision and firmware adaptation.
