Frequently Asked Questions
What is the maximum clock frequency and CPU architecture of the PIC17C43-33I/PT?
The PIC17C43-33I/PT is an 8-bit PIC microcontroller that can operate at a maximum clock frequency of 33 MHz. Its 16-bit address bus allows access to a broad memory space, and the EPROM-based program memory is factory-programmable, making it suitable for production-volume embedded control applications in industrial automation and motor control systems.
How does the EPROM program memory in PIC17C43-33I/PT affect its use in production versus development?
The PIC17C43-33I/PT uses EPROM program memory, which is one-time programmable and suitable for high-volume production builds where the firmware is finalized before manufacturing. Unlike Flash-based PICs, EPROM devices cannot be reprogrammed in-system, so design verification and firmware validation must be completed before committing to mass production. Development work is typically done on emulators or Flash-based equivalents like the PIC17C43 series evaluation boards.
What package does the PIC17C43-33I/PT use and how many pins does it have for I/O connectivity?
The PIC17C43-33I/PT is housed in a QFP (Quad Flat Package) surface-mount package, which provides a high pin count for extensive I/O connectivity. The QFP package allows multiple parallel and serial peripheral interfaces, timers, and I/O ports to connect sensors, actuators, and communication peripherals in industrial control and robotics applications operating up to 33 MHz.
For which legacy embedded control scenarios is the PIC17C43-33I/PT still a viable procurement choice?
The PIC17C43-33I/PT remains viable for legacy system maintenance, spare-part stocking for existing production lines, and OEM repair of installed equipment originally designed around the PIC17C43 architecture running at 33 MHz. Industrial automation controllers, older CNC machine boards, and proprietary embedded systems that cannot be redesigned to newer Flash-based microcontrollers benefit from the continued availability of EPROM-based PIC devices in QFP packages.
