CY8C4247AZI-L423ES Обзор

The Infineon CY8C4247AZI-L423ES is a low-power PSoC® 4200L programmable system-on-chip based on the 32-bit ARM® Cortex®-M0 core, integrating 128 KB of Flash and 16 KB of SRAM in a 48-pin TQFP (7x7 mm) package. The device supports a CPU clock up to 48 MHz and combines programmable analog blocks, a 12-bit SAR ADC, a low-power comparator, and CapSense® touch-sensing hardware with flexible automatic routing between analog and digital resources. The integrated USB 2.0 Full-Speed peripheral and segment LCD driver make it suitable for human-interface and battery-powered products.

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.

This page synthesizes distributor availability, parametric comparison, and PCB-level design notes not collected in the manufacturer datasheet alone, so procurement and engineering teams can shorten the make-or-buy decision for a CY8C4247AZI-L423ES-based design.

Типичное применение

CY8C4247AZI-L423ES подходит для 6 применениеs: 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.

🎮

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.

📺

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.

💊

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.

🏭

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.

🔧

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.

The CY8C4247AZI-L423 and CY8C4247AZI-L423ES share the same PSoC 4200L silicon, 128 KB Flash, 16 KB SRAM, 48-pin TQFP package, and ARM Cortex-M0 core. The ES suffix indicates the silicon revision or factory/quality designation specific to Infineon's ordering code, with no functional difference to the base L423. For prototype work either suffix is acceptable; production runs should use the ES variant if specified in the BOM.
CY8C4247AZI-L423ES vs STM32F072 - which is better for USB HID?
Both the CY8C4247AZI-L423ES and STM32F072 integrate USB 2.0 Full-Speed device controllers, but the PSoC 4200L adds CapSense hardware and programmable UDBs in the same die. The STM32F072 offers a Cortex-M0 at 48 MHz with 128 KB Flash and 16 KB SRAM in LQFP48. For pure USB HID the two are competitive; for products that need capacitive touch buttons or sliders, the CY8C4247AZI-L423ES reduces external components and PCB area.
When should I choose CY8C4247AZI-L423ES over a basic Cortex-M0 MCU?
Choose the CY8C4247AZI-L423ES when the product needs capacitive touch, USB, or segment LCD support without adding an external controller IC. According to the Infineon PSoC 4200L family brief, the programmable analog and digital blocks let one chip replace a base MCU plus a touch controller plus an LCD driver. For cost-sensitive designs without these peripherals, a baseline STM32 or EFM32 part may be cheaper.
What is the best drop-in replacement for CY8C4247AZI-L423ES?
The closest drop-in replacements within the Infineon PSoC 4200L family are CY8C4247AZI-L423 (same silicon without ES suffix) and CY8C4247AZI-L423T (tape and reel packaging variant), both in the same 48-pin TQFP. Cross-brand drop-in options in 48-TQFP from NXP LPC1100 or STM32F072 families require software and peripheral-mapping rework and are not true drop-in. Always verify pinout and power-rail sequencing before substitution.
Can a CY8C4247AZI-L423 replace a CY8C4247AZI-L423ES?
Yes, the CY8C4247AZI-L423 is the same die as CY8C4247AZI-L423ES in the same 48-pin TQFP package, so it is electrically and mechanically compatible. Firmware written for the ES revision runs unmodified on the base L423 part. The reverse migration (L423 to L423ES) is also drop-in. Check the Infineon PCN list for any errata differences between the two order codes before volume production.
Where can I download the CY8C4247AZI-L423ES datasheet PDF?
The official CY8C4247AZI-L423ES datasheet is available on the Infineon product page at infineon.com under the PSoC 4200L family documentation tab. The PSoC 4 architecture technical reference manual and CapSense design guide are also hosted there. For quick reference, third-party sites such as Alldatasheet and Chipdig mirror the PDF; always prefer the Infineon-hosted revision for the latest errata.
What are the key specifications of CY8C4247AZI-L423ES that engineers should know?
The CY8C4247AZI-L423ES is a 48 MHz ARM Cortex-M0 MCU with 128 KB Flash, 16 KB SRAM, USB 2.0 Full-Speed, CapSense CSD, 12-bit 1 Msps SAR ADC, segment LCD driver, and 36 GPIO in a 48-pin TQFP (7x7 mm). It operates from 1.71 V to 5.5 V, with industrial temperature range -40C to +85C and RoHS-compliant lead-free finish. Programmable Universal Digital and Analog Blocks enable custom peripherals without external logic.

Руководство по выбору

Choose the CY8C4247AZI-L423ES when you need a PSoC 4200L with the ES silicon revision specified in your BOM and your build process uses tray packaging. If your BOM does not require the ES revision, the CY8C4247AZI-L423 base part is electrically identical and may have shorter lead time. For SMT production lines, switch to the CY8C4247AZI-L423T tape-and-reel variant to match pick-and-place tooling. All three Infineon parts share the 48-pin TQFP footprint and ARM Cortex-M0 core, so PCB layout and firmware are reusable across the family.

Заметки по проектированию

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.
