Infineon Technologies CY8C5888FNI-LP214T

Overview

CY8C5888FNI-LP214T from Infineon Technologies (formerly Cypress Semiconductor) is a programmable System-on-Chip (PSoC® 5LP) integrating a 32-bit Arm Cortex-M3 CPU, configurable analog/digital peripherals, 256 KB flash, 64 KB RAM, and CapSense® support in a 100-pin TQFP package. It operates from 1.71–5.5 V across –40 to 85 °C, supports full CAN 2.0b, USB 2.0 Full-Speed, and ultra-low-power hibernate mode (300 nA with RAM retention), enabling embedded control in space-constrained industrial HMI systems.

For engineers reviewing the CY8C5888FNI-LP214T datasheet, CY8C5888FNI-LP214T pinout, CY8C5888FNI-LP214T application, or CY8C5888FNI-LP214T equivalent, key selection criteria include its dual ADC capability (delta-sigma + SAR), 24-channel DMA, programmable UDB array for custom logic, USBIO pin integration, and 46–72 GPIO routing flexibility - all critical for mixed-signal IoT edge nodes requiring sensor fusion and real-time control.

Technical Context

The CY8C5888FNI-LP214T implements a tightly coupled architecture where the Arm Cortex-M3 core (up to 80 MHz) interfaces directly with a digital subsystem built around 20–24 Universal Digital Blocks (UDBs), each containing PAL/PLD logic and state machines. Its analog subsystem includes four opamps, four comparators, four 8-bit DACs, and programmable SC/CT blocks supporting PGA, TIA, and mixer functions - enabling on-chip signal conditioning without external components.

Timing is managed via multiple clock sources: a 3–74 MHz IMO (1% accuracy at 3 MHz), 4–25 MHz external crystal oscillator, PLL for 80 MHz system clock, and low-power ILO (1/33/100 kHz). All peripherals - including CAN, USB, TCPWM, and CapSense - are routed through a flexible interconnect fabric that maps any function to any GPIO, eliminating fixed peripheral pin assignments.

FAQ

Does CY8C5888FNI-LP214T support USB device enumeration without external components?

Yes. The part integrates a certified USB 2.0 Full-Speed PHY with internal termination resistors and oscillator, enabling plug-and-play device enumeration on Windows, macOS, and Linux hosts using only the USB_DP/USB_DM pins and standard USB-C or micro-B connectors. No external transceiver, crystal, or ESD protection is required for basic HID or CDC implementations.

What is the maximum operating frequency of the Arm Cortex-M3 core in this device?

The Arm Cortex-M3 core operates at up to 80 MHz, achieved via the internal PLL driven by the IMO or an external crystal. This frequency is fully supported across the entire specified voltage range (1.71–5.5 V) and temperature range (–40 to 85 °C), with timing closure verified in the device's static timing analysis.

Can the delta-sigma ADC and SAR ADC operate simultaneously?

Yes. The device supports concurrent operation of the configurable delta-sigma ADC and up to two independent 12-bit SAR ADCs. Each ADC has dedicated clocking, reference selection (internal 1.024 V or external), and DMA-triggered data transfer - enabling synchronized multi-channel acquisition for sensor fusion applications.

Is CapSense® functionality available on all GPIO pins?

Yes. CapSense® sensing is supported on any GPIO pin within the P0–P15 port ranges, with hardware-accelerated scanning and automatic baseline tracking. Up to 62 self-capacitance or 31 mutual-capacitance sensors can be implemented, and all CapSense® resources (IDACs, sense clocks, CSD block) are allocated dynamically by PSoC Creator during component configuration.
