CY8C4247AZI-L423ES Présentation
A PSoC (Programmable System-on-Chip) is a microcontroller family that pairs a conventional MCU core with Universal Digital Blocks (UDBs) and Universal Analog Blocks (UABs) that the developer can wire into custom peripherals at compile time. Within the broader taxonomy, the PSoC 4200L belongs to the PSoC 4 family, which itself sits under 32-bit ARM Cortex-M microcontrollers and the wider microcontroller and embedded-system hierarchy. This combination of a Cortex-M0 CPU with reconfigurable analog fabric differentiates PSoC from fixed-peripheral MCUs and lets one silicon part implement multiple product variants without board changes.
Key features include active power consumption below 1.2 mA at 3 MHz and a deep-sleep mode of 1.1 µA with SRAM retention. The 12-bit 1 Msps SAR ADC has 16 channels and is supported by four op-amps, two low-power comparators, two 8-bit IDACs, and two 7.5/12-bit VDACs. Communication peripherals include two I2C, three UART, two SPI, USB Full-Speed, CAN, and 36 GPIO with Smart I/O. The device operates from 1.71 V to 5.5 V and the L-series variant adds a segment LCD driver, larger memory and a USB controller compared with baseline PSoC 4000S parts.
The architecture uses a Cortex-M0 core with a 2-cycle 32x32 multiplier and a nested vector interrupt controller. Programmable logic is implemented through UDBs containing PLDs and datapath elements, while analog is implemented through switched-capacitor and continuous-time UABs. This allows peripherals such as custom PWM, quadrature decoders, or sensor front-ends to be synthesized in firmware without an external FPGA or ASIC.
Typical applications include capacitive touch buttons, sliders and proximity sensors for white goods and wearables; USB HID peripherals such as mice, keyboards, and game controllers; low-power glucose meters and portable medical devices; segment-LCD human-machine interfaces for thermostats and instrumentation; and CAN-connected industrial sensor nodes. The device is also used in BLDC fan control and small appliance motor drive subsystems.
A key design consideration is power-budget planning: the low-power modes require the wakeup source and GPIO retention to be configured before sleep, and CapSense® electrodes should be routed with a guarded ground ring to maintain touch SNR. Designers should also evaluate the internal 1.71 V core regulator headroom when the I/O supply is dropped near 1.8 V.

Applications typiques
CY8C4247AZI-L423ES convient pour 6 applications: Capacitive Touch User Interface, USB HID Peripheral Devices, Segment LCD Human-Machine Interface, Battery-Powered Wearable Health Sensor, Industrial CAN Sensor Node, Small Appliance BLDC Motor Control.
Capacitive Touch User Interface
The CY8C4247AZI-L423ES fits capacitive touch interfaces because its integrated CapSense Sigma-Delta (CSD) hardware block scans up to 36 electrodes with a typical SNR greater than 100:1, eliminating the need for an external touch controller. The 48 MHz Cortex-M0 core runs the CapSense firmware plus the application stack, while the 128 KB Flash accommodates tuning tables for buttons, sliders, and proximity sensors. Powered from 1.71 V to 5.5 V, the part supports both 3.3 V and 5 V system rails common in white goods. The 48-pin TQFP package exposes enough GPIO for combined touch buttons plus LED indicators and rotary encoder inputs, simplifying the PCB.
Recommandé
USB HID Peripheral Devices
The CY8C4247AZI-L423ES includes a USB 2.0 Full-Speed device controller with integrated transceiver, so it can enumerate as a HID class device (mouse, keyboard, game controller, custom interface) without an external PHY. The 128 KB Flash stores HID descriptors and application code, while the 16 KB SRAM hosts USB endpoint buffers plus CapSense or sensor data. Operating from a 5 V USB VBUS rail with internal 3.3 V regulation, the part directly powers from the bus. The 48-pin TQFP keeps the PCB area small enough for compact peripherals, and the programmable UDBs can emulate additional endpoints or vendor-specific interfaces.
Recommandé
Segment LCD Human-Machine Interface
The CY8C4247AZI-L423ES integrates a segment LCD driver that supports up to four common lines and 51 segments, replacing an external LCD controller in thermostats, instrumentation, and small appliances. The L-series silicon enables charge-pump-based contrast adjustment, so the display stays readable at low battery voltages down to 1.71 V. The 12-bit SAR ADC and on-chip temperature sensor feed the display with system measurements, while the Cortex-M0 core runs UI logic and button handling. The 48-pin TQFP keeps the BOM small by merging MCU, LCD driver, touch, and ADC into one IC.
Recommandé
Battery-Powered Wearable Health Sensor
The CY8C4247AZI-L423ES suits wearable health sensors thanks to its deep-sleep current of 1.1 µA with SRAM retention and active current below 1.2 mA at 3 MHz / 0.8 V. The 12-bit SAR ADC pairs with the four on-chip op-amps to read photoplethysmography (PPG) or skin-conductance analog front-ends, while the CapSense CSD block adds proximity wake-up without a separate sensor. The 128 KB Flash and 16 KB SRAM are sufficient for an RTOS plus BLE command interface over a companion radio. Operating from a single 3 V coin cell, the part keeps the wearable running for months on a single charge.
Recommandé
Industrial CAN Sensor Node
The CY8C4247AZI-L423ES integrates a CAN 2.0B controller, so it can attach to industrial CAN buses without a discrete CAN controller IC. The 12-bit ADC plus on-chip op-amps digitize bridge sensors, thermocouples, or 4-20 mA loops, while the programmable UDBs implement custom protocol wrappers around the CAN payload. Industrial temperature range (-40C to +85C) and 5.5 V tolerance align with 24 V industrial rails after an external LDO. The 48-pin TQFP footprint keeps the sensor node compact inside an M12 connector housing.
Recommandé
Small Appliance BLDC Motor Control
The CY8C4247AZI-L423ES can drive small brushless DC motors used in fans, pumps, and appliance blowers through its programmable UDBs that generate the six-step or FOC commutation timing. The 12-bit ADC samples back-EMF or current-sense signals synchronously with the PWM, and the integrated comparators provide hardware cycle-by-cycle overcurrent protection. The 48 MHz Cortex-M0 core runs the speed-control loop and CapSense button interface in firmware, while the segment LCD driver displays RPM and status. The 48-pin TQFP package keeps the BOM small for cost-sensitive appliance designs.

Notes de conception
Estimated: at VDD = 3.3 V and active CPU at 48 MHz with all peripherals on, total current consumption is approximately 6-8 mA; in deep-sleep with SRAM retention it drops to 1.1 µA per the Infineon PSoC 4200L datasheet. Place a 1 µF X7R ceramic bypass capacitor as close as possible to each VDD and VDDIO pin, plus a 0.1 µF on VDDD. Tie VDDA to VDD through a ferrite bead and decouple it with 1 µF plus 0.1 µF to keep ADC noise below 1 LSB.
Route CapSense electrodes with a 0.2 mm gap to the surrounding ground hatch and place a ground ring 1-2 mm wide around each sensor to maximize SNR. According to the Infineon CapSense design guide, the CSD sensing traces should not run parallel to switching signals for more than 5 mm; keep them at least 4 mm away from USB D+/D- and switching regulator feedback nodes.
Do not leave the XRES pin floating - it must be pulled to VDDIO through a 10 kohm resistor for normal operation, otherwise the device stays in reset. The P5.0/P5.1 USB D+/D- pins require 22 ohm series resistors plus a 1.5 kohm pull-up on D+ for full-speed enumeration. When using the internal 1.8 V regulator (VDDD), add the recommended 1 µF capacitor on pin 44 to prevent core instability during sleep wake-up transitions.
