Key Features
- 8-bit PIC16 CPU clocked up to 32 MHz with 7 KB Flash and 512 bytes RAM supporting moderately complex control firmware in a compact 14-pin SOIC footprint
- Integrated 16-bit PWM and 10-bit ADC plus DAC channel enabling closed-loop motor control or LED dimming without any external analog components
- Low-cost 14-pin SOIC package with 6-week lead time and 13-year YTEOL making it a reliable long-lifecycle choice for high-volume appliance and industrial designs
Applications
The PIC16F1574-I/SL is suited for single-phase motor speed control, LED driver circuits, and BLDC commutation applications where the 16-bit PWM provides smooth duty-cycle resolution and the 10-bit ADC samples feedback signals at up to 32 MHz throughput. Its integrated DAC channel allows the microcontroller to set analog reference voltages for external comparators or op-amps without a separate DAC IC, reducing BOM cost in smart lighting and power supply control boards. The compact 14-pin SOIC footprint and low unit cost also make it attractive in consumer appliances, smart sensors, and industrial timers where a small 8-bit controller with mixed-signal peripherals replaces discrete logic.

Frequently Asked Questions
How does the 16-bit PWM in the PIC16F1574-I/SL improve motor or LED control resolution compared to an 8-bit PWM?
A 16-bit PWM provides 65,536 duty-cycle steps versus 256 steps for an 8-bit PWM, improving resolution by a factor of 256. At a 32 MHz CPU clock the 16-bit PWM can generate switching frequencies from a few Hz up to hundreds of kHz while still maintaining fine duty-cycle control, enabling smoother LED dimming without visible flicker below 1% brightness and more precise motor torque regulation in BLDC and stepper driver applications.
Can the PIC16F1574-I/SL generate an analog output without an external DAC, and at what resolution?
Yes, the PIC16F1574-I/SL includes an on-chip DAC channel that produces an analog voltage output referenced to the supply or an internal reference. The DAC provides 5-bit resolution (32 output levels) between ground and the reference voltage, allowing the MCU to set a variable analog threshold or reference voltage for an external comparator or op-amp directly from firmware, eliminating the cost and board space of a standalone DAC IC in simple analog output applications.
For a 14-pin SOIC PCB redesign, what is the maximum Flash and RAM available in the PIC16F1574-I/SL?
The PIC16F1574-I/SL provides 7 KB of Flash program memory and 512 bytes of SRAM data memory. This is sufficient to hold a moderately complex firmware image with an RTOS tick, a PID control loop, UART communication, and lookup tables for motor commutation, while the 512 bytes of RAM supports stack frames and circular buffers for sensor data at a 32 MHz execution rate. Designs requiring more memory can step up to larger PIC16F family members in the same SOIC-14 footprint.
When is PIC16F1574-I/SL a lower-cost alternative to a 32-bit Cortex-M0 microcontroller in a simple sensor or actuator design?
The PIC16F1574-I/SL is the lower-cost choice when the control task fits within its 7 KB Flash, 512 bytes RAM, 8-bit data width, and 32 MHz clock, and when the design needs only 14 pins. In single-function applications such as a fan speed controller reading 1 ADC channel and driving 1 PWM output, the PIC16 BOM cost is typically 30% to 50% less than a comparable Cortex-M0 device at 10,000-unit volumes, and the 14-pin SOIC package avoids the fine-pitch soldering challenges of smaller QFN packages used by many Cortex-M0 products.
