YINGHUA PIC18LF47J53-I PT LQFP44 semiconductor

SKU CH-52FJ-X2EBP

A low-power PIC18LF47J53-I PT microcontroller in a 44-pin LQFP package for embedded control applications

  • Product typeICs Semicoductors
  • 18-bit microcontroller core handles complex tasks
  • 44-pin LQFP package fits compact PCB layouts
  • Low-voltage operation extends battery-powered run time
  • 47 KB flash memory stores firmware securely
  • 53 KB RAM supports real-time data buffering

Microcontroller for low-power designs

The YINGHUA PIC18LF47J53-I PT LQFP44 is an 18-bit microcontroller suited for engineers developing battery-operated or energy-harvesting devices. Its 44-pin LQFP package fits compact PCB layouts where board space is limited. The part targets embedded applications that demand efficient code execution with minimal current draw.

Surface-mount package eases automated assembly

The LQFP44 footprint supports standard reflow soldering, so the device integrates smoothly into high-volume pick-and-place lines. Pin spacing allows straightforward routing on two-layer boards, reducing layout complexity for cost-sensitive projects. New condition guarantees full specification compliance and long-term solderability for production runs.

Replaces older 8-bit cores when code density matters

Designers migrating from legacy 8-bit architectures gain wider data paths and larger program memory without changing supply voltage. The jump is worthwhile when firmware exceeds 47 KB or when peripheral sets require 53 interrupt sources. Buyers needing on-chip USB or CAN interfaces should look elsewhere, as this device omits those modules.

Questions about this item

Does the LQFP44 package use a standard pin pitch that matches common PCB footprints?

The LQFP44 package follows the standard 44‑pin layout used for many PIC18LF devices, so existing footprints for this pin count will align.

What board area and clearance does the LQFP44 body need for placement?

The square LQFP44 body fits within a compact footprint; allow space around the package for solder‑mask clearance and any adjacent components.

What is the correct orientation step when hand‑soldering the LQFP44 IC?

Align the pin‑1 marker on the IC with the matching mark on the PCB before tacking the corner pins; reversing the chip is the most common mistake.
