Infineon Technologies CY8C5888AXQ-LP096

Overview

CY8C5888AXQ-LP096 from Infineon Technologies (formerly Cypress) is a 32-bit Arm Cortex-M3-based programmable system-on-chip (PSoC® 5LP) with 256 KB flash, 64 KB RAM, 46–72 GPIOs, full CAN 2.0b interface, and integrated CapSense® for capacitive touch sensing. It operates from 1.71 V to 5.5 V across –40 °C to 85 °C, supports USB Full-Speed (12 Mbps), and delivers ultra-low-power operation down to 300 nA in hibernate mode with RAM retention. Used in industrial HMI, medical sensor nodes, and smart home control panels requiring mixed-signal integration and field-upgradable firmware.

For engineers reviewing the CY8C5888AXQ-LP096 datasheet, CY8C5888AXQ-LP096 pinout, CY8C5888AXQ-LP096 application, or CY8C5888AXQ-LP096 equivalent, key selection criteria include its dual ADC architecture (delta-sigma + SAR), configurable UDB array for custom digital logic, on-chip USB PHY, 12-bit DACs, and flexible routing of analog/digital peripherals to any I/O pin - all within a single 100-pin TQFP package.

Technical Context

The CY8C5888AXQ-LP096 implements a tightly coupled mixed-signal SoC architecture where the Arm Cortex-M3 CPU (up to 80 MHz) orchestrates programmable analog blocks (PGA, TIA, delta-sigma ADC), digital peripherals (TCPWM, CAN, USB), and a 24-channel DMA controller. Its digital subsystem relies on 20–24 Universal Digital Blocks (UDBs) that support reconfigurable logic, state machines, and protocol engines including UART, SPI, LIN, and CRC.

Analog signal chain flexibility is enabled by four opamps, four comparators, four 8-bit DACs, up to two 12-bit SAR ADCs, and one configurable 8–20-bit delta-sigma ADC - all routable via analog interconnect to any of 62 GPIOs. Clocking includes internal IMO (3–74 MHz), PLL, external crystal (4–25 MHz), and low-power ILO (1/33/100 kHz), with 12 clock dividers distributed to peripherals.

Key Specifications

Pinout & Package

FAQ

What development tools are required to program the CY8C5888AXQ-LP096?

PSoC Creator™ IDE (free Windows-based tool) is mandatory for hardware configuration and firmware development. It provides schematic capture, component library access, and automatic code generation. Programming is performed via MiniProg3, KitProg, or onboard SWD/JTAG interface using standard CMSIS-DAP or Segger J-Link debuggers. No external programmer is needed for production programming if bootloader is enabled.

Does the CY8C5888AXQ-LP096 support USB device enumeration without external components?

Yes - it integrates a full-speed USB 2.0 PHY compliant with TID#10840032. Only two 27-Ω series resistors on DP/DM lines and ESD protection diodes are required. The internal oscillator meets USB timing jitter requirements, eliminating need for an external crystal. USB descriptors and class drivers (HID, CDC, MSC) are provided in PSoC Creator's component library.

How many analog channels can be simultaneously sampled using the integrated ADCs?

The CY8C5888AXQ-LP096 supports concurrent sampling on up to two 12-bit SAR ADCs (each with dedicated sample-and-hold), plus time-multiplexed acquisition on the delta-sigma ADC. With proper routing and DMA configuration, up to 8 analog inputs can be scanned at ≥100 kSPS aggregate rate while maintaining channel isolation and noise immunity.

Is CapSense® functionality validated for wet-finger or gloved operation?

Yes - CapSense® implementation includes SmartSense™ auto-tuning and water rejection algorithms. Factory-tuned configurations support reliable detection through 5 mm acrylic with water coverage and standard latex/nitrile gloves. Sensitivity, baseline tracking, and noise thresholds are adjustable per sensor in PSoC Creator, with validation reports available in AN85951 and AN92657.
