A PSoC, or programmable system-on-chip, is an MCU architecture that integrates a processor with configurable digital blocks, analog blocks, and peripherals. It belongs to the microcontroller and embedded semiconductor hierarchy, while extending a conventional microcontroller with programmable mixed-signal functionality. This integration allows product designs to adapt digital control logic and analog signal paths without relying on a large collection of discrete components.
The CY8C5567LTI-079 provides a 67 MHz Cortex-M3 core, 128 KB flash organized as 128K by 8 bits, and 32-bit architecture. The listed operating-voltage options are 2.5 V, 3.3 V, and 5 V. Its 68-QFN package supports compact surface-mount assembly, while the PSoC 5 family provides programmable resources suited to embedded control, signal acquisition, and mixed-signal interface tasks.
The 128 KB on-chip flash provides nonvolatile program storage for firmware, configuration data, and lookup tables. The 67 MHz processing rate supports responsive control loops and event-driven embedded software. The programmable architecture distinguishes this device from a fixed-function microcontroller by allowing suitable digital logic, analog functions, and interface behavior to be configured for the target application.
Typical uses include industrial control panels, sensor acquisition systems, communications equipment, consumer interfaces, and compact embedded products. A design can place sensing, control, and communication functions around the same PSoC device, reducing board area and the number of separately managed functional blocks. Firmware and peripheral configuration should still be validated against the exact device variant and its operating limits.
When laying out a board, treat the 68-QFN package as a dense surface-mount footprint and follow the manufacturer land-pattern and pin-assignment tables. Confirm supply-voltage compatibility, decoupling requirements, programming connections, exposed-pad treatment, and the intended temperature grade before release to production. The device's compact package does not eliminate the need for careful high-speed return paths and thermal planning.
This page consolidates the core PSoC 5 specifications, sourcing guidance, pin-availability considerations, and practical design notes into one engineering reference. It also distinguishes verified drop-in candidates from broader functional equivalents so that PCB and firmware decisions are based on package and device-level compatibility rather than name similarity alone.

Typische Anwendungen
CY8C5567LTI-079 ist geeignet für 6 Anwendungs: Industrial Control Panels, Sensor Acquisition and Conditioning, Communications Equipment, Consumer Interface Controllers, Data Acquisition Gateways, Programmable Signal-Control Systems.
Industrial Control Panels
The CY8C5567LTI-079 fits compact industrial control panels that combine user input, status indication, sensor conditioning, and real-time supervisory logic. Its 32-bit ARM Cortex-M3 core runs at 67 MHz, while 128 KB of flash stores application firmware and 32 KB of SRAM provides working memory for control state. The programmable digital and analog resources can consolidate interface logic around one device instead of distributing simple functions across several fixed-function ICs. Design the power rails and I/O protection for the industrial environment, and confirm the exact temperature grade, isolation strategy, and EMC requirements before production deployment.
Empfohlen
Sensor Acquisition and Conditioning
The CY8C5567LTI-079 is well suited to sensor-acquisition products because its PSoC architecture combines a 67 MHz Cortex-M3 processor with programmable analog and digital functions. A design can use the analog resources for signal conditioning and the digital blocks for filtering or configurable logic while firmware handles calibration, linearization, and data logging. The 128 KB flash supports substantial code and configuration storage, and 32 KB of SRAM accommodates acquisition buffers. Validate input ranges, sampling accuracy, and conversion timing against the manufacturer datasheet, especially when the external sensor produces signals near a supply rail.
Empfohlen
Communications Equipment
The CY8C5567LTI-079 can serve as the control processor in compact communications equipment requiring deterministic embedded behavior and flexible mixed-signal interfacing. Its 32-bit Cortex-M3 core operates at 67 MHz, providing sufficient instruction throughput for protocol handling, supervisory logic, and configurable digital functions. The 128 KB flash holds firmware and protocol configuration, while 32 KB of SRAM supports packet buffers and stack usage. For a production design, match the peripheral set and package pins to the selected communications controller, provide continuous clocking for stable timing, and isolate external interfaces against surge and ESD events.
Empfohlen
Consumer Interface Controllers
The CY8C5567LTI-079 is appropriate for compact consumer interfaces that combine touch or button input, indicator control, and programmable logic. Its PSoC 5 architecture allows digital control functions and suitable analog resources to be integrated within the microcontroller, reducing component count in space-constrained products. A 67 MHz Cortex-M3 core supports responsive interaction logic, while 128 KB of flash accommodates application firmware, calibration values, and interface tables. Because consumer products can be exposed to ESD and unusual supply transients, specify protected I/O paths and validate the completed product against its applicable safety, EMC, and environmental requirements.
Empfohlen
Data Acquisition Gateways
The CY8C5567LTI-079 can act as the local control engine in a data-acquisition gateway that gathers sensor information, applies configuration, and forwards processed results. Its 128 KB flash provides nonvolatile storage for firmware and lookup data, while the 32-bit Cortex-M3 core at 67 MHz can execute protocol and filtering tasks concurrently with configurable digital logic. The 68-QFN 8 mm by 8 mm package supports compact board construction but requires careful escape routing and thermal management. Define the acquisition bandwidth, buffering strategy, communications interface, and update mechanism in the firmware architecture before freezing the PCB layout.
Empfohlen
Programmable Signal-Control Systems
The CY8C5567LTI-079 suits programmable signal-control systems where a fixed logic sequence is insufficient and configurable digital and analog behavior is valuable. Its PSoC 5 resources can implement application-specific control sequences, while the 67 MHz Cortex-M3 processor manages configuration, sequencing, and supervisory functions. The 128 KB flash allows independent code segments for firmware and field configuration, and 32 KB of SRAM supports working queues and timing state. Validate signal bandwidth and deterministic behavior in the final analog and digital implementation, and use the manufacturer configuration guidance to avoid resource conflicts or unsuitable timing assumptions.

Wichtigste Unterscheidungsmerkmale
- Closest ordering-format alternative retains the complete listed core configuration (vs. CY8C5567LTI-079T)
- Target is explicitly identified within the CY8C55 family (vs. CY8C5867LTI-LP028)
Designhinweise
Use the manufacturer QFN land pattern rather than estimating pad and mask geometry from the 8 mm by 8 mm body size. Place input and output decoupling capacitors close to their associated supply pins, provide a low-impedance ground reference, and route high-current returns without splits beneath the device. Confirm exposed-pad connection, paste mask, solder mask, and assembly clearance in the official package drawing before PCB release.
Select the power architecture around the listed 2.5 V, 3.3 V, and 5 V operating options and verify every external peripheral against the resulting rail. Place bulk energy storage and local ceramic bypass where they can minimize supply-loop inductance. Review startup, brownout, clock, and I/O limits in the manufacturer datasheet; do not infer absolute maximum limits from the nominal operating-voltage list.
Do not treat a shared package and a similar family name as sufficient proof of firmware compatibility. The CY8C5567LTI-079T candidate changes the ordering format, while CY8C5867LTI-LP028 represents a different device variant whose memory and peripheral differences require a separate review. For either substitution, compare pin assignments, interrupt vectors, clock requirements, programming procedures, and device configuration identifiers against the manufacturer datasheets.
