Product details
Overview
CY8C4147LQE-S273 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified 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 (SCB), eight TCPWM modules, CAN 2.0B with TTCAN support, and programmable analog blocks - deployed in automotive body electronics, smart sensors, and human-machine interface systems.
For engineers reviewing the CY8C4147LQE-S273 datasheet, CY8C4147LQE-S273 pinout, CY8C4147LQE-S273 application, or CY8C4147LQE-S273 equivalent, key selection criteria include AEC-Q100 Grade-S qualification, on-chip CAPSENSE™ SNR >5:1, CAN 2.0B/TTCAN capability, Deep Sleep current of 2.5 µA, and GPIO flexibility across 54 pins with programmable drive modes.
Technical Context
The device implements a tightly integrated mixed-signal SoC architecture: the Arm® Cortex®-M0+ core executes firmware while programmable digital logic (Smart I/O) and analog blocks (CTB opamps, SAR ADC, IDACs, LPCs) operate concurrently under hardware routing control. Its clock system combines a 4–33 MHz ECO, PLL for 48-MHz core timing, WCO, IMO (±2%), and ILO - enabling precise time-triggered execution and low-power wake-up.
Capacitive sensing uses sigma-delta (CSD) modulation with hardware-accelerated SmartSense tuning, delivering >5:1 SNR and water-tolerant operation without external calibration. The CAN block supports full CAN 2.0B frame handling and time-triggered scheduling (TTCAN), with dedicated message RAM and error counters compliant with ISO 11898-1.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4147AZI-S475 | Same PSoC™ 4100S Plus family, but 64-pin TQFP package, Grade-E (–40°C to +125°C), no CAN block. | Lacks CAN interface; suited for non-networked high-temp environments like engine bay sensors. | Select when CAN is unnecessary and extended temperature range or larger pin count is required. |
| SPC560B50L5 | 32-bit Power Architecture MCU, 64 MHz, 512 KB flash, 48 KB RAM, dual CAN, but no integrated CAPSENSE™ or programmable analog. | Requires external touch controller and analog signal chain; targets powertrain rather than HMI. | Choose for legacy Power Architecture toolchain compatibility or higher compute throughput in non-touch applications. |
Compared with CY8C4147AZI-S475 and SPC560B50L5, CY8C4147LQE-S273 uniquely integrates CAPSENSE™, CAN, and programmable analog in a compact 48-pin QFN - making it optimal for cost-sensitive, space-constrained automotive HMI nodes requiring both sensing and networking.

FAQ
Does CY8C4147LQE-S273 support CAN FD?
No. This device implements CAN 2.0B with TTCAN extensions only. It does not support CAN FD data rates or flexible data-length frames. For CAN FD, consider Infineon's AURIX™ TC3xx series or later-generation PSoC™ 6 devices with CAN FD controllers.
Can CAPSENSE™ operate during Deep Sleep mode?
Yes. CAPSENSE™ CSD hardware remains fully functional in Deep Sleep mode with 2.5 µA system current. SmartSense auto-tuning runs autonomously without CPU intervention, enabling always-on touch wake-up with sub-10 ms response time.
What development tools are officially supported?
Infineon officially supports ModusToolbox™ (Eclipse-based IDE with PDL and CAPSENSE™ middleware) and legacy PSoC™ Creator. Both provide schematic-driven configuration, API generation, and debug via KitProg3 or MiniProg3. Third-party Arm® tools (Keil, IAR) are compatible via generated GCC/ARM projects.
Is external flash required for firmware updates?
No. The device includes 128 KB on-chip flash with Read Accelerator and supports field firmware updates via bootloader using UART, I²C, or CAN. Dual-bank flash is not present, so over-the-air updates require careful memory partitioning and rollback handling in application code.
