Infineon Technologies CY8C5287AXI-LP095

Overview

CY8C5287AXI-LP095 from Infineon Technologies (formerly Cypress Semiconductor) is a 32-bit programmable System-on-Chip (PSoC® 5LP) integrating an 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 ambient, delivers up to 80 MHz performance, and supports USB 2.0 Full-Speed (12 Mbps) with internal oscillator - used in industrial HMI, medical sensor hubs, and low-power embedded control systems.

For engineers reviewing the CY8C5287AXI-LP095 datasheet, CY8C5287AXI-LP095 pinout, CY8C5287AXI-LP095 application, or CY8C5287AXI-LP095 equivalent, key selection criteria include its 72-pin TQFP package, 24-channel DMA, 12-bit SAR ADC with 1.024 V ±1% reference, ultra-low-power sleep mode (2 µA), and flexible peripheral routing to any GPIO.

Technical Context

The CY8C5287AXI-LP095 implements a tightly integrated mixed-signal SoC architecture centered on an Arm Cortex-M3 core with cache and PHUB-based DMA controller. Its digital subsystem uses 24 Universal Digital Blocks (UDBs) for user-defined logic, timers, PWMs, UARTs, SPIs, and CRC generators - all routable via DSI to any I/O.

Analog resources include a 12-bit SAR ADC with programmable sample rate and input range, dual comparators, 8-bit DAC, and CapSense® engine supporting up to 62 self- or mutual-capacitance sensors. Clocking combines IMO (3–74 MHz), PLL (up to 80 MHz), ILO (1/33/100 kHz), and 32.768-kHz RTC crystal support with 12 programmable dividers.

FAQ

Does CY8C5287AXI-LP095 support USB device enumeration without an external crystal?

Yes. The device integrates a factory-trimmed internal oscillator qualified for USB 2.0 Full-Speed (12 Mbps) operation per TID#10840032 certification. It achieves ±0.25% accuracy across voltage and temperature ranges, eliminating the need for a 12-MHz crystal and associated load capacitors in USB peripheral designs.

What is the maximum number of CapSense® sensors supported, and how is noise immunity achieved?

CY8C5287AXI-LP095 supports up to 62 self-capacitance or mutual-capacitance sensors using its dedicated CapSense® CSD block. Noise immunity is achieved through spread-spectrum modulation, shield-driven electrodes, automatic baseline tracking, and hardware-accelerated correlation filtering - delivering >60 dB rejection of 50/60 Hz line noise and fast transient interference.

Can the 12-bit SAR ADC operate concurrently with USB transfers and DMA-driven PWM generation?

Yes. The ADC, USB, and TCPWM peripherals each have dedicated DMA request lines routed to the 24-channel PHUB. Independent channel arbitration allows simultaneous ADC sampling (triggered by timer), USB packet transmission, and PWM duty-cycle updates - all without CPU intervention or timing conflict.

Is the 72-pin TQFP variant of CY8C5287AXI-LP095 pin-compatible with other CY8C52LP family members?

No. CY8C5287AXI-LP095 uses a 100-pin TQFP package (not 72-pin). The "LP095" suffix denotes the 100-pin variant with industrial temperature grade (–40 to +85 °C) and specific flash/RAM configuration (256 KB/64 KB). Pin compatibility exists only within identical package types across the CY8C52LP family, such as CY8C5267AXI-LP095 (same 100-pin TQFP).
