Product details
Overview
CY8C4247LTQ-M475 from Infineon is a PSoC™ 4200M programmable system-on-chip integrating an Arm® Cortex®-M0 CPU (48 MHz), 128 kB flash, 16 kB SRAM, and reconfigurable analog/digital blocks. It supports capacitive sensing (CSD), segment LCD drive, dual CAN interfaces, and operates from 1.71–5.5 V across –40°C to +105°C for industrial motor control and HMI applications.
For engineers reviewing the CY8C4247LTQ-M475 datasheet, CY8C4247LTQ-M475 pinout, CY8C4247LTQ-M475 application, or CY8C4247LTQ-M475 equivalent, this page delivers verified technical context, validated pin functions, real-world use cases, and confirmed alternative options for embedded design validation and BOM optimization.
Technical Context
The device implements a tightly coupled mixed-signal architecture where the 48 MHz Cortex-M0 core orchestrates programmable analog blocks-including four opamps with comparator/ADC-buffer modes-and four IDACs usable on any GPIO. Its SAR ADC achieves 1 Msps at 12-bit resolution with hardware-accelerated CSD sensing delivering >5:1 SNR and water tolerance.
Digital flexibility stems from four Universal Digital Blocks (UDBs), each with 8 macrocells and an 8-bit datapath, plus eight TCPWM blocks supporting center-aligned PWM and comparator-triggered kill signals. Two independent CAN 2.0B controllers enable robust industrial networking, while four SCBs provide runtime-reconfigurable I²C/SPI/UART functionality.

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-M482 | Same PSoC™ 4200M family; 256 kB flash, 32 kB SRAM, identical peripherals and pinout - larger memory footprint. | Preferred for firmware-over-the-air (FOTA) updates or complex GUI stacks requiring >128 kB code space. | Select when future firmware expansion or dual-bank secure boot is required; pin-compatible drop-in upgrade path. |
| STM32G474RET6 | Arm Cortex-M4 @ 170 MHz; 512 kB flash, 128 kB SRAM; no integrated CSD or LCD drive; requires external opamps for analog front-end. | Suited for high-performance motor control with FPU/DSP extensions but lacks hardware capacitive sensing acceleration. | Choose when floating-point computation or higher clock speed dominates over integrated analog programmability and touch capability. |
Compared with CY8C4247LTQ-M475, CY8C4248LQI-M482 offers scalable memory for evolving firmware needs without redesign, while STM32G474RET6 trades integrated analog flexibility for raw computational throughput and ecosystem breadth - making the former ideal for memory-constrained mixed-signal upgrades and the latter better for compute-intensive, externally conditioned sensor systems.

FAQ
Does CY8C4247LTQ-M475 support USB connectivity?
No, CY8C4247LTQ-M475 does not include a USB PHY or USB controller. It provides four SCBs for I²C, SPI, and UART only. For USB-enabled designs, Infineon's PSoC™ 4000S or PSoC™ 6 families are recommended alternatives with integrated USB 2.0 FS controllers and associated firmware stacks.
What debug interfaces are supported?
CY8C4247LTQ-M475 supports Serial Wire Debug (SWD) via dedicated SWDCK and SWDIO pins. It does not support JTAG. Debugging is fully compatible with Infineon's ModusToolbox™ and third-party Arm-compliant tools like Segger J-Link and ST-Link v2 (in SWD mode).
Can the opamps operate during Deep Sleep mode?
Yes - all four opamps can remain active in Deep Sleep mode with typical current consumption of 120 µA per opamp. This enables continuous analog signal monitoring (e.g., battery voltage supervision or sensor biasing) while the CPU and most digital blocks are powered down.
Is the CAN peripheral compliant with ISO 11898-1:2015?
Yes - both CAN controllers comply with ISO 11898-1:2015 (CAN 2.0B specification) for data link layer functionality. Physical layer compliance requires pairing with a certified CAN transceiver (e.g., Infineon TLE6250 or TI SN65HVD230) meeting ISO 11898-2/3 standards.
