Infineon Technologies CY8C5888FNI-LP210T

Overview

CY8C5888FNI-LP210T from Infineon Technologies (formerly Cypress) is a 32-bit Arm Cortex-M3-based programmable system-on-chip (PSoC® 5LP) integrating configurable analog/digital peripherals, 256 KB flash, 64 KB RAM, and full-speed USB 2.0 interface. It operates from 1.71–5.5 V across –40 to 85 °C, supports CapSense® for up to 62 sensors, and delivers ultra-low-power operation with 300 nA hibernate mode. Used in industrial HMI, medical sensor hubs, and battery-powered IoT edge nodes requiring mixed-signal reconfigurability.

For engineers reviewing the CY8C5888FNI-LP210T datasheet, CY8C5888FNI-LP210T pinout, CY8C5888FNI-LP210T application, or CY8C5888FNI-LP210T equivalent, key selection criteria include its dual ADC architecture (delta-sigma + SAR), 24-channel DMA, programmable UDB array for custom logic, CAN 2.0b support, and flexible I/O routing to any peripheral - all critical for embedded control systems demanding hardware-software co-design agility.

Technical Context

The CY8C5888FNI-LP210T implements a tightly integrated PSoC 5LP architecture centered on an 80 MHz Arm Cortex-M3 core with cache, PHUB-based DMA controller, and Digital Filter Block (DFB) for fixed-point signal processing. Its analog subsystem includes a 20-bit delta-sigma ADC, two 12-bit SAR ADCs, four opamps, and four programmable SC/CT blocks enabling PGA, TIA, and mixer configurations.

Digital flexibility stems from 24 universal digital blocks (UDBs) supporting user-defined peripherals like UART, SPI, LIN, CRC, quadrature decoders, and gate-level logic - all routable via DSI to any of 62 GPIOs. Clocking combines IMO (1–74 MHz), PLL (up to 80 MHz), and low-power oscillators (1/33/100 kHz, 32.768 kHz), with 12 clock dividers distributed to peripherals and I/O.

FAQ

Does CY8C5888FNI-LP210T support USB device mode only, or can it act as a USB host?

No, CY8C5888FNI-LP210T implements only USB 2.0 Full-Speed device-mode functionality (TID#10840032 certified). It lacks USB OTG or host controller logic, and cannot enumerate as a USB host. External USB host capability requires companion ICs such as the MAX3421E or CH375B.

Can the delta-sigma ADC operate simultaneously with the SAR ADCs?

Yes - the PSoC 5LP architecture allows concurrent operation of the 20-bit delta-sigma ADC and both 12-bit SAR ADCs, provided clock domains and routing resources are allocated without conflict. This is confirmed in Section 8.2 and 8.3 of the datasheet (Rev. *O, pp. 54–55).

What is the maximum operating frequency of the internal main oscillator (IMO)?

The internal main oscillator (IMO) is factory-trimmed to ±1% accuracy at 3 MHz and supports programmable frequencies from 3 MHz to 74 MHz. At 74 MHz, accuracy degrades to ±5%, as specified in Table 11-12 (Electrical Specifications, Rev. *O, p. 124).

Is the 32.768 kHz watch crystal oscillator (WCO) mandatory for RTC functionality?

Yes - the real-time clock (RTC) module requires the 32.768 kHz external crystal oscillator (WCO) for accurate timekeeping. The internal low-frequency oscillator (ILO) lacks sufficient stability (±1000 ppm) for RTC use; WCO accuracy is ±20 ppm, meeting typical RTC timing requirements.
