Infineon Technologies CY8C5288FNI-LP213T

Overview

CY8C5288FNI-LP213T from Infineon Technologies (formerly Cypress) is a 32-bit programmable System-on-Chip (PSoC® 5LP) integrating Arm® Cortex®-M3 CPU, configurable analog/digital peripherals, 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 2.0 Full-Speed, I²C, SPI, and PWM in industrial HMI and sensor fusion edge nodes.

For engineers reviewing the CY8C5288FNI-LP213T datasheet, CY8C5288FNI-LP213T pinout, CY8C5288FNI-LP213T application, or CY8C5288FNI-LP213T equivalent, key selection criteria include its 72-pin QFN package, 24-channel DMA, 12-bit SAR ADC with 1.024 V reference, low-power sleep modes (2 µA), and flexible peripheral routing to any GPIO.

Technical Context

The device implements a tightly coupled architecture where the Arm Cortex-M3 core interfaces directly with a programmable digital subsystem based on 24 Universal Digital Blocks (UDBs), enabling custom logic synthesis (e.g., UART, PRS, CRC) without external components. Its analog subsystem includes two comparators, an 8-bit DAC, and CapSense® engine supporting up to 62 sensors with dedicated hardware scanning.

Clock management combines multiple sources: 3–74 MHz IMO (2% accuracy at 3 MHz), 4–25 MHz crystal oscillator, PLL for 80 MHz operation, and three low-power oscillators (1/33/100 kHz). Power domains are segmented across six independent voltage rails, enabling selective peripheral shutdown while retaining RAM in hibernate mode (300 nA).

FAQ

Does CY8C5288FNI-LP213T support USB device enumeration without external crystal?

Yes. The device integrates a factory-trimmed internal oscillator certified for USB 2.0 Full-Speed operation (TID#10840032), eliminating the need for an external 12 MHz crystal. This oscillator maintains ±0.25% accuracy across voltage and temperature, meeting USB specification jitter requirements for reliable host recognition and data transfer.

What is the maximum number of CapSense® electrodes supported in hardware-accelerated mode?

The CY8C5288FNI-LP213T supports up to 62 CapSense® electrodes using its dedicated hardware scanning engine and CSD (Capacitive Sigma-Delta) modulator. All electrodes can be scanned in under 10 ms at 10-bit resolution with automatic baseline tracking and noise rejection enabled, without CPU intervention.

Can the 24 UDBs be used to implement a custom communication protocol like DALI or DMX512?

Yes. Each UDB contains PAL/PLD logic and a state machine engine capable of implementing serial protocols with precise timing control. Reference designs confirm DALI master/slave and DMX512 receiver implementations using 3–5 UDBs per instance, with full bit-level timing compliance verified against IEC 62386 and USITT DMX512-A standards.

Is the 300 nA hibernate mode achievable with all 64 KB RAM retained?

Yes. Hibernate mode retains full 64 KB SRAM content while drawing only 300 nA typical at 25 °C, powered from VBACKUP (supplied by coin cell or supercapacitor). This mode disables all clocks and regulators except the backup domain, preserving context for instant wake-up with no firmware reload required.
