Infineon Technologies CY8C5868AXI-LP032

Overview

CY8C5868AXI-LP032 from Infineon Technologies (formerly Cypress) is a programmable System-on-Chip (PSoC® 5LP) integrating a 32-bit Arm Cortex-M3 CPU, configurable analog/digital peripherals, up to 256 KB flash, 64 KB RAM, and CapSense® support. It operates from 1.71–5.5 V across –40 to +85 °C, delivers up to 80 MHz performance, and supports USB Full-Speed, CAN 2.0b, and multiple ADC/DAC configurations for embedded control in industrial HMI and sensor fusion systems.

For engineers reviewing the CY8C5868AXI-LP032 datasheet, CY8C5868AXI-LP032 pinout, CY8C5868AXI-LP032 application, or CY8C5868AXI-LP032 equivalent, key selection criteria include its dual ADC architecture (delta-sigma + SAR), 46–72 GPIO routing flexibility, ultra-low-power sleep modes (2 µA), integrated USBIO pins, and PSoC Creator™-enabled hardware/firmware co-design flow.

Technical Context

The CY8C5868AXI-LP032 implements a tightly coupled mixed-signal SoC architecture where the Arm Cortex-M3 core interfaces with a programmable digital subsystem (20–24 UDBs) and analog subsystem (4 opamps, 4 comparators, 4 DACs, delta-sigma and SAR ADCs). Peripheral functions are routed dynamically via Digital System Interconnect (DSI) and Analog Routing Matrix, enabling pin-agnostic peripheral assignment.

Its clocking system includes a 3–74 MHz IMO (1% accuracy at 3 MHz), PLL for 80 MHz operation, low-power ILO (1/33/100 kHz), and 32.768 kHz watch crystal support. Power management features six independent domains, boost regulator (0.5–5 V), and three low-power states: Active, Sleep (2 µA), and Hibernate (300 nA with RAM retention).

Key Specifications

FAQ

What development tools are required to program CY8C5868AXI-LP032?

PSoC Creator™ IDE (free download from Infineon) is the primary tool, supporting schematic-based hardware design, C firmware development, and debug via SWD/JTAG. It includes GCC compiler support and integrates with Keil MDK. Programming requires MiniProg3, KitProg2, or onboard debugger on CY8CKIT-059/CY8CKIT-050 evaluation kits.

Does CY8C5868AXI-LP032 support secure boot and firmware encryption?

Yes - it includes flash security features such as read protection, write protection, and secure bootloader support. Flash memory can be partitioned into protected regions, and the device supports cryptographic key storage in nonvolatile latches (NVLs) to enforce authenticated firmware updates and prevent unauthorized access to sensitive code.

Can all GPIOs be used for CapSense® sensing?

Yes - any GPIO (up to 62 pins) can be configured for CapSense® using the CSD (CapSense® Sigma-Delta) block. The device supports both self-capacitance and mutual-capacitance scanning, with built-in IDACs, shield drivers, and noise rejection algorithms - eliminating need for external capacitors or dedicated touch controllers.

Is USB functionality available without external crystal?

Yes - USB 2.0 Full-Speed operation uses the internal oscillator (IMO) with automatic calibration against the USB SOF packet, eliminating need for an external 12 MHz crystal. This reduces BOM cost and board space while maintaining USB certification (TID#10840032) and ±0.25% timing accuracy.
