Product details
Overview
CY8C4247BZI-L479T from Infineon is a 32-bit Arm® Cortex®-M0 microcontroller in the PSoC™ 4200L family, integrating programmable analog (4 opamps, 2 comparators, 12-bit SAR ADC), digital (8 UDBs, 4 SCBs, 8 TCPWM), and capacitive sensing (CSD) subsystems. It operates from 1.71–5.5 V, delivers 48 MHz CPU performance, and supports Deep Sleep mode at 20 nA. Used in industrial HMI touch panels with integrated LCD drive and motor control feedback.
For engineers reviewing the CY8C4247BZI-L479T datasheet, CY8C4247BZI-L479T pinout, CY8C4247BZI-L479T application, or CY8C4247BZI-L479T equivalent, key selection criteria include its 94 GPIO count with CAPSENSE™/analog/digital reconfiguration, dual CAN interface for industrial networking, USB Full-Speed device capability, and SmartSense™-enabled self-tuning capacitive sensing.
Technical Context
The device implements a tightly coupled Arm® Cortex®-M0 core with 256 kB flash and 32 kB SRAM, paired with a configurable analog fabric including four CTBm opamp blocks supporting comparator mode and ADC input buffering. Its digital architecture combines eight universal digital blocks (UDBs) for custom logic with fixed-function peripherals including four serial communication blocks (SCBs) that runtime-reconfigure as I²C/SPI/UART.
Timing and control are managed by eight 16-bit TCPWM blocks supporting center-aligned PWM and comparator-triggered kill signals for motor drive safety, while two CSD blocks deliver >5:1 SNR and water-tolerant touch sensing. The 124-ball VFBGA package supports up to 94 programmable I/Os with per-pin drive strength, slew rate, and mode configuration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4248LQI-BL553 | Same PSoC™ 4200L architecture but in 80-pin QFN; 128 kB flash, 16 kB SRAM; no USB interface. | Suitable for space-constrained industrial controllers where USB is unnecessary and lower memory suffices. | Select when board layout favors QFN, memory requirements are ≤128 kB, and USB device functionality is not required. |
| STM32G474RET6 | Arm® Cortex®-M4F @ 170 MHz; 512 kB flash, 128 kB SRAM; no integrated capacitive sensing or programmable analog fabric. | Better for compute-intensive motor control or DSP tasks, but requires external touch controller and analog signal chain components. | Select when floating-point math, higher clock speed, or larger memory footprint is critical, and external analog/touch components are acceptable. |
Compared with CY8C4247BZI-L479T, CY8C4248LQI-BL553 trades USB and memory for smaller QFN packaging, while STM32G474RET6 offers higher CPU performance at the cost of losing integrated analog programmability and hardware-accelerated capacitive sensing - making it less suitable for touch-integrated, low-power embedded HMI designs.

FAQ
What development tools are supported for CY8C4247BZI-L479T?
CY8C4247BZI-L479T is fully supported by Infineon's free PSoC™ Creator IDE, which provides schematic-based hardware design, automatic analog/digital routing, and pre-verified component libraries. It also integrates with Arm®-compliant toolchains including GCC, Keil MDK, and IAR Embedded Workbench for firmware development and debugging via SWD or JTAG.
Does CY8C4247BZI-L479T support USB device functionality without external components?
Yes. CY8C4247BZI-L479T integrates a full-speed USB 2.0 device controller with on-die transceivers, requiring only a USB connector and standard termination resistors. It supports Battery Charger Detection (BCD) and operates at 12 Mbps without external PHY or level shifters, enabling direct connection to host PCs or charging ports.
Can the opamps in CY8C4247BZI-L479T operate during Deep Sleep mode?
Yes. All four CTBm opamp blocks retain full functionality in Deep Sleep mode, drawing typical current of 1.2 µA per opamp. They support continuous analog signal conditioning, comparator operation, and ADC input buffering while the CPU and most digital resources are powered down - essential for always-on sensor monitoring.
How many CAN interfaces does CY8C4247BZI-L479T provide, and are they compliant with ISO 11898-1?
CY8C4247BZI-L479T integrates two independent CAN 2.0B controllers compliant with ISO 11898-1. Each supports bit rates up to 1 Mbps, programmable sample points, and hardware message filtering. External CAN transceivers (e.g., TJA1042T) are required for physical layer interfacing, as the device lacks integrated transceivers.
