Product details
Overview
CY8C4147LQE-S473 from Infineon is an AEC-Q100 Grade-S (–40°C to +105°C) automotive-qualified PSoC™ 4100S Plus programmable system-on-chip featuring a 48-MHz Arm® Cortex®-M0+ CPU, 128 KB flash, 16 KB SRAM, integrated CAPSENSE™ capacitive sensing with SmartSense auto-tuning, and a CAN 2.0B controller with TTCAN support - deployed in body control modules and door module ECUs.
For engineers reviewing the CY8C4147LQE-S473 datasheet, CY8C4147LQE-S473 pinout, CY8C4147LQE-S473 application, or CY8C4147LQE-S473 equivalent, key selection criteria include its dual-mode CAN/TTCAN capability, Deep Sleep current of 2.5 µA with operational analog, 12-bit 1-Msps SAR ADC, and reconfigurable SCB blocks supporting I²C/SPI/UART/LIN on-the-fly.
Technical Context
The CY8C4147LQE-S473 integrates a hard-macro CAN 2.0B controller with time-triggered communication (TTCAN) compliance, enabling deterministic message scheduling for automotive networked systems. Its eight TCPWM blocks support quadrature decoding and comparator-triggered kill signals for motor safety logic.
Capacitive sensing is implemented via a dedicated CSD block delivering >5:1 SNR and water tolerance, paired with hardware-accelerated SmartSense tuning - eliminating manual calibration. The device uses a 4–33 MHz ECO with PLL to generate the 48-MHz system clock, while retaining independent 32-kHz WCO and ±2% IMO for low-power timing.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4147AZI-S475 | Same core, 64-pin TQFP package, higher GPIO count (54), no CAN block | Lacks CAN 2.0B/TTCAN; suited for non-networked touch-centric modules only | Select when CAN is unnecessary and board layout favors TQFP with larger keep-out area |
| SPC560B50L5 | Power Architecture, 64 MHz, 512 KB flash, ASIL-B certified, includes CAN FD | Higher ASIL coverage, CAN FD bandwidth, but lacks integrated CAPSENSE™ and programmable analog | Select when functional safety certification depth exceeds PSoC™ 4100S Plus scope and external touch IC is acceptable |
Compared with CY8C4147AZI-S475 and SPC560B50L5, the CY8C4147LQE-S473 uniquely balances CAN/TTCAN, CAPSENSE™, and low-power analog in a compact QFN - ideal for cost-sensitive, space-constrained automotive human-machine interfaces requiring both networking and touch.

FAQ
Does CY8C4147LQE-S473 support CAN FD?
No. The device implements a CAN 2.0B controller with TTCAN extensions, not CAN FD. It supports standard 11-bit identifiers and up to 8-byte payloads at bit rates up to 1 Mbps. CAN FD requires separate silicon architecture and is found in Infineon's AURIX™ or newer PSoC™ 6 families.
What development tools are required for CAPSENSE™ tuning?
PSoC™ Creator IDE (v4.4 or later) with the CAPSENSE™ Tuner tool is required. It connects via KitProg2/MiniProg3 to perform real-time SNR analysis, baseline tracking adjustment, and SmartSense parameter optimization - no external oscilloscope or logic analyzer needed.
Is external flash memory needed for firmware updates?
No. The 128 KB on-chip flash supports dual-bank operation, enabling seamless in-field firmware updates with rollback capability. The Read Accelerator ensures zero-wait-state execution during bank switching, maintaining real-time performance during update cycles.
Can GPIO pins be used simultaneously for CAPSENSE™ and analog ADC input?
Yes - any GPIO pin can be configured for CAPSENSE™ sensing or as an ADC input channel, but not concurrently on the same pin. Time-multiplexing is supported: e.g., scan touch buttons during idle, then reconfigure selected pins for ADC sampling during active sensor acquisition phases.
