Product details
Overview
CY8C4147LQS-S263T from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-grade PSoC™ 4100S Plus microcontroller featuring a 48-MHz Arm® Cortex®-M0+ CPU, 128 KB flash, 16 KB SRAM, and integrated CAPSENSE™ capacitive sensing with SmartSense auto-tuning. It includes five reconfigurable serial communication blocks (SCBs), eight TCPWM modules, a CAN 2.0B controller with TTCAN support, and operates from 1.71 V to 5.5 V.
For engineers reviewing the CY8C4147LQS-S263T datasheet, CY8C4147LQS-S263T pinout, CY8C4147LQS-S263T application, or CY8C4147LQS-S263T equivalent, this device is selected for automotive body electronics requiring integrated analog sensing, motor control timing, secure random number generation, and robust CAN communication in extended temperature environments.
Technical Context
The device integrates a programmable analog subsystem with two opamps (supporting ADC input buffering and Deep Sleep operation), a 12-bit 1-Msps SAR ADC with channel sequencer and averaging, and two low-power comparators. Its digital architecture combines fixed-function peripherals-including CAN 2.0B with time-triggered capability-and configurable logic via Smart I/O blocks.
Clock management includes a 4–33 MHz ECO, PLL for 48-MHz core clock, 32-kHz WCO, ±2% IMO, and 32-kHz ILO. The GPIO system supports up to 54 pins across QFN packages, all configurable for CAPSENSE™, analog, or digital functions with programmable drive strength and slew rate.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4147LQI-S263 | Same die, QFN-48 package, but Grade-I (–40°C to +85°C); no AEC-Q100 qualification. | Suitable for non-automotive industrial or consumer applications where extended temperature and automotive qualification are not required. | Select only if AEC-Q100 and Grade-S operation are unnecessary; lower cost but not automotive-certified. |
| SPC560B50L5 | Power Architecture-based 32-bit MCU, 64 MHz, 512 KB flash, 48 KB RAM, ASIL-B capable, but no integrated CAPSENSE™ or programmable analog. | Targets higher ASIL requirements (e.g., steering column modules) but requires external touch controller and analog signal chain. | Choose when functional safety certification (ISO 26262) is mandatory and programmable analog is not needed. |
Compared with CY8C4147LQI-S263 and SPC560B50L5, the CY8C4147LQS-S263T uniquely combines AEC-Q100 Grade-S qualification, hardware-accelerated CAPSENSE™, and reconfigurable analog/digital blocks-reducing component count and layout complexity for mid-tier automotive human-machine interfaces.

FAQ
What is the maximum operating frequency of the Arm® Cortex®-M0+ core in CY8C4147LQS-S263T?
The core runs at a maximum of 48 MHz, achieved via internal PLL multiplication of the 4–33 MHz external crystal oscillator (ECO) or ±2% internal main oscillator (IMO). This frequency is fully supported across the full Grade-S temperature range (–40°C to +105°C) and voltage range (1.71 V to 5.5 V), with zero-wait-state flash execution enabled by the Read Accelerator.
Does CY8C4147LQS-S263T support hardware-based capacitive touch sensing without external components?
Yes. It integrates CAPSENSE™ sigma-delta (CSD) hardware with SmartSense auto-tuning, enabling robust touch button/slider/wheel implementation using only PCB traces and no external RC networks. The analog front-end includes dedicated CSD modulator, IDACs, and shield drivers-all configurable via PSoC™ Creator or ModusToolbox™.
Can the CAN peripheral operate in time-triggered mode, and what clock source does it require?
Yes, the integrated CAN 2.0B block supports time-triggered CAN (TTCAN) with synchronized message transmission windows. It uses the 32-kHz watch crystal oscillator (WCO) as its time base for deterministic timing, independent of the 48-MHz system clock, ensuring jitter-free scheduling even during CPU sleep or clock scaling events.
How many serial communication interfaces can be active simultaneously on CY8C4147LQS-S263T?
Up to five serial communication blocks (SCBs) can be configured and operated concurrently-each independently set to I²C, SPI, UART, or LIN slave mode. Their routing is handled automatically by the PSoC™ hardware interconnect, allowing simultaneous use of, for example, I²C for sensor readout, SPI for display update, UART for debug, and two CAN nodes via SCB-based LIN emulation or direct CAN block usage.
