CY8C5568AXI-060 - 67MHz Cortex-M3 PSoC 5 | Infineon

The Infineon CY8C5568AXI-060 is a 32-bit ARM Cortex-M3 PSoC 5 microcontroller rated for operation up to 67 MHz, with 256 KB of embedded flash memory and a 100-lead TQFP package measuring 14 x 14 mm. The device combines a conventional microcontroller core with programmable digital blocks, analog resources, and dedicated peripherals, making it suitable for compact embedded-control systems that need more configurability than a fixed-function MCU. A programmable system-on-chip, or PSoC, is a microcontroller platform that integrates processing, memory, programmable logic, analog conversion, and specialized peripherals into one device. The PSoC architecture places these resources into a broader embedded semiconductor hierarchy: PSoC 5, ARM Cortex-M3, 32-bit microcontroller, embedded controller, and system-on-chip. This integration allows designers to adapt signal acquisition, control logic, and communication behavior without moving to a larger discrete component count. Key features include a 67 MHz maximum Cortex-M3 operating frequency, 32-bit processing capability, and 256 KB of flash memory for firmware. The listing also identifies 64 KB of SRAM. Flexible operating-voltage support covering 1.8 V, 3.3 V, and 5 V operation expands compatibility with industrial, consumer, and embedded equipment. A 100-lead TQFP package provides a conventional surface-mount format with accessible leads for inspection, rework, and prototype assembly. The Cortex-M3 core includes dedicated debugging and trace resources, including Flash Patch and Breakpoint, Data Watchpoint and Trace, and Instrumentation Trace Macrocell functions. These features support breakpoint-based debugging and serial data tracing during firmware development. The programmable architecture can consolidate functions such as digital control, analog signal conditioning, and communications into one microcontroller-based design. Typical applications include industrial control modules, sensor acquisition systems, building automation equipment, consumer interfaces, and compact embedded products. The PSoC 5 platform is particularly useful when a design requires both deterministic microcontroller control and configurable analog or digital peripheral functions. The 256 KB flash capacity also provides room for application firmware, boot code, configuration data, and update handling. When laying out a board, follow the manufacturer pin-description table for every signal, including programming, reset, clock, ground, power, and peripheral assignments. Keep sensitive analog and communication routes away from switching nodes and high-current return paths, and provide the decoupling network specified by the device datasheet. This product reference combines the core device identity, package information, embedded-memory details, search-intent guidance, and practical implementation considerations in one engineering-focused reference. It also distinguishes verified device facts from parameters that must be confirmed in the manufacturer datasheet before PCB release.
