CY8C5888AXI-LP096 Overview
A PSoC (Programmable System-on-Chip) is a microcontroller category that combines a CPU core, programmable analog front-ends (op-amps, DACs, ADCs, comparators), programmable digital blocks (UDBs), and routable interconnect fabric on one chip. The PSoC 5LP family specifically pairs an industry-standard ARM Cortex-M3 core with the proprietary UDB/UFB fabric, allowing designers to implement custom peripherals in silicon rather than in external components, reducing BOM cost and board area.
Key features include 1 Delta-Sigma 20-bit ADC, 2 SAR 12-bit ADCs, multiple DACs, comparators, op-amps, and 24 UDBs for digital logic synthesis. The CY8C5888AXI-LP096 also provides USB Full-Speed, CAN, I2C, SPI, UART, and GPIO. Its CapSense touch sensing capability enables capacitive touch buttons, sliders, and proximity sensors without external ICs.
The architecture runs up to 80 MHz, delivers up to 100 DMIPS, and supports industrial temperature range (-40°C to +85°C for "I" suffix). The Cortex-M3 core is paired with a DMA controller and a digital filter processor (DFB) for signal conditioning offloaded from the CPU. The wide 1.71–5.5 V supply allows direct operation from batteries, 3.3 V regulators, or 5 V rails.
Typical applications include industrial control, HMI with touch, motor control, USB peripherals, sensor conditioning, and low-power IoT endpoints. The combination of an integrated Delta-Sigma ADC and programmable analog makes it well suited to bridge sensors and wired communication.
When designing with this part, plan GPIO and analog pin allocations against the package pinout early because the 100-TQFP has a fixed ball-out. Use PSoC Creator or ModusToolbox for schematic-level configuration of the UDBs and analog blocks; firmware brings up the rest.

Typical Applications
CY8C5888AXI-LP096 is suitable for 7 applications: Industrial HMI with CapSense Touch, Motor Control and BLDC Drive, USB Peripherals and HID Devices, Sensor Signal Conditioning and IoT Edge Nodes, Audio Processing and Effects, Automotive Body Electronics, Smart Home and Appliance Control.
Industrial HMI with CapSense Touch
The CY8C5888AXI-LP096 is well suited to industrial human-machine interface (HMI) panels with capacitive touch buttons, sliders, and proximity sensors. Its integrated CapSense hardware (via IDAC + comparator + UDB logic) eliminates external touch ICs, while the 80 MHz Cortex-M3 handles debouncing, gesture recognition, and LCD drive. The 256 KB flash stores graphics libraries and touch parameter sets. The 1.71–5.5 V supply supports direct 24 V-to-5 V regulated rails common in industrial panels. Pin-to-pin compatibility within the CY8C58LP family lets designers scale between LP096, LP035, and LP039 variants without PCB changes.
Recommended
Motor Control and BLDC Drive
For brushless DC (BLDC) and stepper motor control, the CY8C5888AXI-LP096 provides a tightly integrated solution. The 80 MHz Cortex-M3 core runs FOC (field-oriented control) algorithms at the required PWM update rates, while the 2 SAR ADCs sample phase currents synchronously to the PWM. The programmable UDBs implement dead-time insertion, hardware fault shutdown, and quadrature encoder decoding without burdening the CPU. The 20-bit Delta-Sigma ADC handles low-bandwidth analog feedback (potentiometer position, temperature). Industrial temperature grade (-40 °C to +85 °C) supports HVAC and appliance motor applications.
Recommended
USB Peripherals and HID Devices
The CY8C5888AXI-LP096 integrates USB Full-Speed with on-chip transceiver, eliminating external PHY ICs for HID-class peripherals such as keyboards, mice, game controllers, and custom input devices. The Cortex-M3 handles USB stack and HID report processing, while UDBs implement custom endpoint behavior. The 256 KB flash fits USB stacks (e.g., Cypress USBFS middleware) with room for vendor-specific descriptors. The 5.5 V supply tolerance is comfortable for USB bus-powered designs. CapSense integration enables touch-enabled USB peripherals without adding a dedicated touch controller.
Recommended
Sensor Signal Conditioning and IoT Edge Nodes
For IoT edge nodes reading multiple analog sensors, the CY8C5888AXI-LP096 combines precision and density. The 20-bit Delta-Sigma ADC handles strain gauges, RTDs, and thermocouples, while the SAR ADCs sample accelerometers and current shunts. The programmable op-amps condition amplifier signal chains before digitization, eliminating external analog front-ends. The 1.71–5.5 V supply supports battery operation from a single Li-ion cell. The Cortex-M3 plus DMA controller routes data to UART/SPI/CAN for wired transmission, with UDBs implementing custom protocol bits.
Recommended
Audio Processing and Effects
Audio applications benefit from the CY8C5888AXI-LP096's 20-bit Delta-Sigma ADC and DAC for high-fidelity capture and playback. The Cortex-M3 runs reverb, equalization, and dynamics processing algorithms in firmware, while the DFB (digital filter block) offloads FIR/IIR filtering from the CPU. Multiple audio channels can be supported through the SAR ADCs. The 256 KB flash stores audio effects libraries and presets. The 5 V supply tolerance simplifies designs with single-supply op-amps. UDBs handle I2S/TDM protocol generation for external DAC chains.
Recommended
Automotive Body Electronics
For non-safety automotive body electronics - lighting controls, seat modules, climate panels - the CY8C5888AXQ-LP096 variant (Q-suffix automotive qualification) of the same die is the appropriate choice. CapSense supports touch-enabled door handles and control surfaces. CAN connectivity is native. The wide supply tolerance handles load-dump transients on 12 V automotive rails. Designers prototype with the LP096 industrial version and migrate to the Q-suffix for production AEC-Q100 qualification.
Recommended
Smart Home and Appliance Control
White-goods and smart-home appliances benefit from the CY8C5888AXI-LP096's combination of CapSense (touch panels), motor control (PWM + timers + ADC), and connectivity (UART, SPI, I2C for Wi-Fi/BLE co-processors). The 80 MHz Cortex-M3 coordinates user interface, sensor monitoring, and actuator drive on one chip. The Cortex-M3's deterministic interrupt latency simplifies support for IEC 60730 Class B safety requirements in household appliances. The industrial temperature grade supports refrigerator and oven environments.

Key Differentiators
- Programmable analog and digital fabric on-chip (vs CY8C5287AXI-LP095 (PSoC 3 / 8051))
- Higher core frequency than 5688 variant (vs CY8C5688AXI-LP099)
- Automotive-qualified twin with same die (vs CY8C5888AXQ-LP096)
Design Notes
The CY8C5888AXI-LP096 supports a wide 1.71–5.5 V supply range, but the internal core logic requires a 1.2 V regulated rail generated by the on-chip LDO. Place a 1 µF X7R ceramic bypass capacitor on each VDD and VDDD pin as close as physically possible to the package - typically within 2 mm trace length. For USB applications, route the internal voltage regulator bypass with a 1 µF capacitor on the VBOOST pin and ensure VDDIO matches the logic level of external interfaces.
The TQFP-100 package has a 0.5 mm lead pitch, which requires fine-pitch PCB layout. Use 0.1 mm trace/space rules minimum and consider microvia-in-pad for ground fan-out from the exposed thermal pad (if present). Keep analog traces (ADC inputs, op-amp outputs) routed away from digital switching signals, especially the SWD clock line. Provide a contiguous ground plane on layer 2 for return paths - the TQFP-100's center pad (if present) should be soldered to ground for thermal dissipation.
Do not confuse the CY8C5888AXI-LP096 (PSoC 5LP / Cortex-M3) with the CY8C5888 from the original PSoC 5 family (different silicon revision). When designing with Pin-to-Pin compatible alternatives such as CY8C5868AXI-LP035, verify that your PSoC Creator/ModusToolbox project target matches the actual silicon - otherwise analog block routing may fail at compile time. For automotive applications, choose the Q-suffix variant (CY8C5888AXQ-LP096) explicitly; the I-suffix part is not AEC-Q100 qualified.
Compliance Information
The 'I' suffix indicates industrial grade (not AEC-Q100 qualified). Use CY8C5888AXQ-LP096 for automotive AEC-Q100 qualification. RoHS and REACH compliance per Infineon product page and DigiKey listing. Lead-free per package suffix 'I' (industry convention).
