PIC16F1454-I/P

Microcontrollers Overview

The PIC16F1454-I/P is a 14-pin, 8-bit Flash microcontroller from the PIC16(L)F145X family. It features an 8192-word program memory and 1024 bytes of data SRAM. The device operates at clock frequencies up to 48 MHz with instruction cycles as fast as 83 ns. It supports a supply voltage range of 2.3V to 5.5V and includes a USB 2.0 compliant Serial Interface Engine (SIE). Key peripherals include two 10-bit PWM modules, an Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART), Master Synchronous Serial Port (MSSP), and three timers.

Microcontrollers Feature Summary

• Integrates a USB 2.0 compliant Serial Interface Engine (SIE) supporting Low Speed and Full Speed transfers with self-tuning capabilities.
• Features a high-performance RISC CPU architecture optimized for C compilers with only 49 instructions and automatic context saving during interrupts.
• Includes flexible oscillator structures with a factory-calibrated 16 MHz internal block and software-selectable frequency ranges down to 31 kHz.
• Provides enhanced timer resources including Timer0, Enhanced Timer1, and Timer2, alongside two 10-bit PWM modules.

Microcontrollers Applications

• USB-enabled peripheral devices requiring host detection via interrupt-on-change on D+/D- lines.
• Industrial control systems utilizing RS-232, RS-485, or LIN compatible communication interfaces.
• Motor control applications leveraging complementary waveform generation and auto-shutdown sources.

Microcontrollers Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the application design accommodates the specified operating voltage range of 2.3V to 5.5V. Ensure that firmware development tools support the PIC16 instruction set and memory architecture defined in the official datasheet.

Microcontrollers Selection Notes

Select this component when a USB interface is required without external crystals due to the self-tuning feature. Consider the 14-pin PDIP package for through-hole assembly requirements. Evaluate the 1024-byte data memory limit against application stack and variable needs before finalizing the selection.

Microcontrollers Part Context

This device belongs to the PIC16(L)F145X family of 14/20-pin Flash microcontrollers. It shares the core CPU and many peripheral features with the PIC16F1455 and PIC16F1459 models. The primary distinction lies in the reduced pin count and the absence of analog peripherals like ADC and comparators found in other family members.
