Microchip PIC16F1503T-E/STVAO 8-Bit Microcontroller Overview
The Microchip PIC16F1503T-E/STVAO is a high-performance, low-power 8-bit microcontroller unit (MCU) from Microchip Technology’s extensive PIC16F family. Built on an enhanced mid-range core with a 16-level deep hardware stack and 49 instructions, this MCU is engineered for cost-sensitive yet performance-driven embedded applications requiring precision analog integration, robust core independent peripherals, and efficient operation.
At its heart, the MCU operates at speeds up to 20 MHz, delivering a solid balance of processing power and energy efficiency. It features 3.5 KB of Flash program memory and 128 bytes of RAM, providing sufficient resources for a wide range of control-oriented tasks. A key strength of the PIC16F1503 family is its rich set of integrated analog and digital peripherals, which significantly reduce external component count, system size, and total cost.
Core Features and Capabilities:
Enhanced Core and Flexible Oscillator: The device includes an internal 16 MHz oscillator with ±1% accuracy, allowing it to run without an external crystal, thereby saving board space and cost. It supports multiple clock modes for power management.
Advanced Analog Integration: A standout feature is its sophisticated analog suite. It incorporates a 10-bit Analog-to-Digital Converter (ADC) with up to 12 channels, a 5-bit Digital-to-Analog Converter (DAC) module, and two comparators. This makes it exceptionally well-suited for sensor interface, battery monitoring, and analog signal conditioning.
Core Independent Peripherals (CIPs): These hardware modules operate without constant CPU intervention, freeing it up for other tasks and simplifying software design. Key CIPs include:
Complementary Waveform Generator (CWG): Outputs complementary PWM signals for precise motor control and power conversion.
Windowed Watchdog Timer (WWDT): Enhances system reliability by monitoring code execution within a predefined "window" of time.
Timer0 and Timer1: 8-bit and 16-bit timers/counters with gate control.
Communication Interfaces: It provides essential serial communication protocols, including MSSP (I²C/SPI) and an EUSART (LIN/RS-485 capable), enabling easy connectivity with other peripherals, sensors, and host processors.
mTouch Sensing: The device supports Microchip's capacitive sensing (mTouch) technology, enabling the design of modern, reliable touch interfaces without mechanical buttons.
Low-Power Operation: With nanoWatt XLP technology, the MCU is ideal for battery-powered applications, offering extremely low current consumption in Sleep mode.
Package and Applications:
The "T" in the part number denotes it is supplied in a TSSOP-20 package, which is compact and suitable for automated surface-mount assembly. The "-E" suffix indicates it is an enhanced mid-range core part with the advanced peripheral set.
Typical applications for the PIC16F1503T-E/STVAO are diverse, including:
Consumer electronics (appliance control, touch panels)
Automotive (sensor modules, interior controls)
Industrial (power supplies, motor control, sensors)
Internet of Things (IoT) edge nodes
ICGOOODFIND: The PIC16F1503T-E/STVAO is a highly integrated and versatile 8-bit MCU.
