CY8C5688AXI-LP099 Descripción general
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.

Aplicaciones típicas
CY8C5688AXI-LP099 es adecuado para 6 aplicacións: 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.
Recomendado
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.
Recomendado
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.
Recomendado
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.
Recomendado
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.
Recomendado
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.

Notas de diseño
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.
Información de cumplimiento
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.
