The device is housed in a 100-pin TQFP package measuring 14 mm by 14 mm. A PSoC 5, or Programmable System-on-Chip, combines a microcontroller core with programmable digital and analog peripheral blocks in one integrated circuit. Within the semiconductor hierarchy, it is a microcontroller and embedded processor; within the PSoC family, it provides a configurable platform for mixed-signal control, communications, and signal-processing designs. The CY8C5567AXI-019 belongs to the CY8C55 series and provides a 32-bit processing architecture, a 67 MHz maximum clock frequency, and 128 KB of flash storage. Its 100-pin TQFP package exposes substantially more device connections than smaller microcontroller packages, making it appropriate for systems that require numerous external interfaces while remaining compatible with conventional surface-mount assembly. Programmable system-on-chip architecture allows designers to allocate peripheral resources according to the application rather than relying on a fixed combination of dedicated interface blocks. This architecture is useful when a design needs adaptable digital control, analog measurement, communications, or timing functions implemented within a single microcontroller package. Typical application areas include industrial monitoring and control, connected sensor equipment, embedded automation, consumer devices, communication equipment, and general-purpose embedded control. The 128 KB of flash provides a defined code-storage region for firmware, while the 100-pin package supports the larger pin count often needed for external sensors, communications links, status indicators, and actuators. PCB implementation should follow the manufacturer’s land pattern, pin-connection table, and recommended decoupling guidance. Pay particular attention to supply routing, analog and digital return paths, exposed programming or test connections, and the package’s thermal requirements. The 14 mm by 14 mm footprint is physically larger than common 48-pin and 64-pin MCU packages, so enclosure and connector spacing should be checked before layout release. This page consolidates the verified device identity, core architecture, memory capacity, clock rate, package information, sourcing workflow, and engineering guidance into one decision-oriented reference. It also distinguishes the exact ordered MPN from its tape-and-reel packaging variant while avoiding unrelated parts that do not share a verified drop-in footprint.

The dual-core architecture lets system firmware run real-time user code on the Cortex-M4 while the M0+ handles radio stack, sensors, and always-on housekeeping, dramatically reducing system power. Key features include Bluetooth LE 5.x radio with 2 Mbps PHY, 1 MB application flash, 288 KB SRAM, 104-pin WLCSP footprint, hardware crypto accelerators (AES, SHA, TRNG), capacitive touch sensing, USB device, and 12-bit SAR ADC with up to 1 Msps. Independent chip with low-power modes down to deep-sleep current under 5 uA (per Infineon datasheet). The 40 nm process enables aggressive leakage reduction without sacrificing analog performance. Typical applications include fitness bands and smart watches, BLE-based smart home hubs, asset tracking beacons, wireless sensor nodes, HMI touch panels, and connected medical devices. The wide operating voltage (1.7 V to 9 V battery and Wi-Fi analog frontend (AFE)) supports coin-cell, Li-ion, and USB-powered designs in a single BOM. When designing with this part, pay attention to WLCSP PCB layout: 0.4 mm pitch requires NSMD pads, microvia-in-pad, and controlled-impedance routing for the antenna. Use Infineon ModusToolbox and the PSoC 63 BSP to leverage the dual-core project template for ARM-based firmware development. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone.
