CY8C5688AXI-LP099 Übersicht
A PSoC 5LP device is a mixed-signal programmable SoC that combines a Cortex-M3 CPU, programmable universal digital blocks (UDBs), programmable analog blocks (SC/CT blocks), and fixed-function peripherals on a single die. Within the broader hierarchy it belongs to microcontrollers (MCU) -> 32-bit MCU -> ARM Cortex-M MCU -> programmable SoC -> embedded processing. The architecture lets designers replace discrete op-amps, comparators, ADCs, DACs and timing glue logic with on-chip configurable blocks, shortening BOM count and PCB area.
Key features of the CY8C5688AXI-LP099 include 24 UDBs for custom digital logic, four op-amps with PGA modes, four DACs, two SAR ADCs at up to 1 Msps, four TCPWM blocks, USB full-speed, CAN, I2C, SPI, UART, and an integrated CapSense touch engine. The wide 1.71 V to 5.5 V supply simplifies direct connection to a single Li-ion cell, 3.3 V logic rails, or 5 V industrial buses without external level shifters.
The Cortex-M3 core with single-cycle multiply and a DMA controller delivers deterministic interrupt response and sustained DSP throughput at 80 MHz, while the UDB array accelerates state machines, custom peripherals and glue logic in hardware, off-loading the CPU. The on-chip regulator and low-power modes (Sleep, Deep Sleep, Hibernate) enable battery-friendly designs.
Typical applications include industrial HMI panels with CapSense, motor control front-ends, USB/CAN sensor hubs, programmable sensor conditioning, medical portable instruments, and home appliances. Designers choose the CY8C5688AXI-LP099 when they want analog configurability that a stock Cortex-M MCU does not provide.
When designing, populate the unused analog block pins to defined states to avoid leakage, and provide a 1 uF + 100 nF decoupling pair adjacent to each VDD/VBAT pin to keep the internal regulator stable. Place the 32.768 kHz watch crystal as close as practical to the XTAL pins and route its traces over a continuous ground pour to limit radiated emissions.

Typische Anwendungen
CY8C5688AXI-LP099 ist geeignet für 6 Anwendungs: Industrial HMI with CapSense, USB Sensor Hub, Motor Control Front-End, Programmable Sensor Conditioning, Medical Portable Instrument, Home Appliance Control.
Industrial HMI with CapSense
The CY8C5688AXI-LP099 is a strong fit for industrial HMI panels because its CapSense Sigma-Delta hardware implements up to 62 touch sensors without external touch ICs, while the four on-chip op-amps drive LED backlight current-sense and the four TCPWM blocks generate precise dimming PWM. The 256 KB Flash hosts a full emWin / LVGL graphical stack plus a Modbus RTU slave over UART, and the 1.71 V to 5.5 V supply allows direct 24 V industrial-bus operation after a small buck stage. Designers gain BOM reduction by replacing a touch controller, op-amp array, and timing IC with a single PSoC.
Empfohlen
USB Sensor Hub
In USB sensor hubs the CY8C5688AXI-LP099 integrates a USB Full-Speed device controller, four op-amps for sensor excitation, and two 12-bit SAR ADCs at 1 Msps to digitize analog sensors directly. The Cortex-M3 at 80 MHz plus DMA offloads USB HID class handling into the background, while the 64 KB SRAM buffers high-rate sensor streams before USB frames are scheduled. This single-chip solution replaces a discrete MCU plus USB controller plus analog front-end, reducing PCB area and BOM count in industrial sensor pods.
Empfohlen
Motor Control Front-End
The CY8C5688AXI-LP099 supports motor-control front-ends via its four TCPWM blocks, four op-amps and 12-bit SAR ADC, providing current sensing, back-EMF digitizing, and PWM generation for trapezoidal or FOC algorithms in low-to-mid power BLDC and PMSM drives. The 24 UDBs implement custom encoder interfaces or Hall-sensor de-bouncing in hardware, off-loading the 80 MHz Cortex-M3. Wide 1.71 V to 5.5 V supply simplifies bootstrap supplies, and the 100-pin TQFP exposes enough GPIO for multi-axis coordination in compact driver boards.
Empfohlen
Programmable Sensor Conditioning
The CY8C5688AXI-LP099 excels in programmable sensor-conditioning modules because its four op-amps (configurable as PGA, transimpedance, or difference amps) and four 8-bit DACs support auto-zero bridge excitation, RTD linearization, and thermistor compensation on-chip. The two SAR ADCs simultaneously digitize the conditioned signal and a reference channel for ratiometric measurements. The Cortex-M3 runs linearization tables and I2C/SPI communication, while the configurable analog fabric replaces 4 to 6 precision op-amps typically used in instrumentation front-ends, cutting BOM and improving thermal drift tracking.
Empfohlen
Medical Portable Instrument
The CY8C5688AXI-LP099 is well suited to medical portable instruments because its wide 1.71 V to 5.5 V supply allows direct Li-ion operation, and Hibernate mode at a few microamperes preserves battery between measurements. The 256 KB Flash and 64 KB SRAM host a real-time ECG / pulse-oximetry DSP pipeline plus USB-CDC data export, while the integrated 12-bit SAR ADC handles electrode and SpO2 photodiode readout. The Cortex-M3 with single-cycle MAC executes FIR / IIR filters in real time, and PSoC Creator medical-class libraries shorten FDA submission risk in low-to-medium classification devices.
Empfohlen
Home Appliance Control
In home appliances such as washing machines, induction cooktops and smart thermostats, the CY8C5688AXI-LP099 replaces the main control MCU plus discrete op-amp / comparator / timer ICs, reducing component count and improving reliability. Its four TCPWM blocks drive triac firing, relay control and buzzer tones, while the integrated op-amps sense NTC temperature and zero-cross detectors. CapSense enables sealed glass-front user interfaces, and the 256 KB Flash hosts the appliance firmware plus a graphical menu with minimal external memory. Industrial -40C to +85C operation covers garage and outdoor appliance variants.

Designhinweise
Place a 1 uF X7R ceramic plus a 100 nF X7R ceramic as close as possible to each VDD/VBAT/VDDA pin pair of the CY8C5688AXI-LP099. The internal regulator that powers the Cortex-M3 core is sensitive to high-frequency impedance; without local decoupling you may see reset issues or USB Full-Speed enumeration failures. The 100-TQFP package has multiple VDD pins - every one must be decoupled separately, not shared through a single capacitor.
Route the 32.768 kHz watch crystal traces short and symmetric, with a continuous ground pour underneath and guard traces around them to limit noise coupling into the CapSense sigma-delta block. Keep analog routing (op-amp inputs, ADC inputs, reference) away from TCPWM PWM outputs and digital switching nodes, and use a star-ground topology so analog and digital return currents join only at the exposed pad ground under the TQFP.
Do not leave unused analog block pins floating - configure them in PSoC Creator as Analog Disable / High-Z analog to prevent leakage that can corrupt adjacent ADC measurements. Avoid programming Flash above 1.71 V during Hibernate transitions or below 5 V if your design relies on the internal IMO at full 80 MHz; if the supply droops, the CPU will hang on a flash wait state. Always validate SWD / JTAG clock rate against VDDIO before debug attach, since PSoC Creator's default 1.5 MHz SWD may fail at very low VDD.
Compliance-Informationen
RoHS and REACH compliant per Infineon product page. Industrial temperature grade -40C to +85C; choose CY8C5688AXI-LP106 for extended -40C to +105C operation. No AEC-Q100 variant in this family; for AEC-Q100 designs use Cypress / Infineon automotive PSoC families such as Traveo II.
