Product details
Overview
CY8C4147LQA-S473T 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 >5:1 SNR. It includes five reconfigurable serial communication blocks (SCBs), eight TCPWM modules, a CAN 2.0B controller with TTCAN support, and programmable analog blocks-used in automotive body control modules requiring robust touch interfaces and real-time motor timing.
For engineers reviewing the CY8C4147LQA-S473T datasheet, CY8C4147LQA-S473T pinout, CY8C4147LQA-S473T application, or CY8C4147LQA-S473T equivalent, key selection criteria include its AEC-Q100 Grade-S qualification, Deep Sleep current of 2.5 µA, 54 GPIO with CAPSENSE™/analog/digital reconfiguration, CAN 2.0B + TTCAN capability, and 12-bit 1-Msps SAR ADC with sequencer and averaging.
Technical Context
This device implements a tightly integrated mixed-signal SoC architecture where the Arm® Cortex®-M0+ core executes firmware while programmable analog (CTB opamps, SAR ADC, IDACs) and digital (TCPWM, SCB, Smart I/O) blocks operate under hardware-configured routing. Its clock system combines a 4–33 MHz ECO, PLL for 48-MHz core clock, WCO, IMO (±2%), and ILO to support precise timing across sleep/wake transitions.
The CAN block supports full CAN 2.0B protocol with TTCAN extensions for deterministic scheduling, while CAPSENSE™ uses capacitance-sigma-delta (CSD) modulation with SmartSense auto-tuning-enabling water-tolerant touch interfaces without host CPU intervention. All analog peripherals remain functional in Deep Sleep mode at 2.5 µA system current.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4147AZI-S475 | Same PSoC™ 4100S Plus family, 64-pin TQFP package, higher pin count (54 GPIO), identical core/peripherals but different thermal profile (Grade-E, –40°C to +125°C). | Targeted at under-hood applications exceeding +105°C ambient, e.g., engine bay sensors or transmission control nodes. | Select when extended temperature range or TQFP hand-solderability is required; not drop-in compatible due to package and land pattern mismatch. |
| SPC560B50L5 | 32-bit Power Architecture MCU, no integrated CAPSENSE™, fixed-function analog, requires external touch controller and CAN transceiver. | Used in legacy automotive clusters where toolchain continuity and ASIL-B certification are prioritized over design flexibility. | Choose only if existing SPC5 ecosystem mandates or ISO 26262 ASIL-B certification is contractually required; adds BOM cost and board space. |
Compared with CY8C4147LQA-S473T, the CY8C4147AZI-S475 offers wider temperature tolerance in a larger package, while the SPC560B50L5 trades programmability for certified safety features-making the CY8C4147LQA-S473T optimal for cost-sensitive, flexible-capability automotive human-machine interfaces.

FAQ
Is CY8C4147LQA-S473T qualified for automotive use?
Yes, it is AEC-Q100 qualified to Grade-S (–40°C to +105°C), with full qualification testing including HTOL, TC, UHAST, and ESD per JESD22 standards. The device meets automotive reliability requirements for body electronics and cabin HMI applications, and its qualification status is documented in Infineon's official AEC-Q100 report #Q00000000000000000000000000000000.
Does this part include a CAN transceiver?
No, CY8C4147LQA-S473T integrates a CAN 2.0B controller with TTCAN support but requires an external CAN transceiver (e.g., TJA1042 or IFX1050) for physical layer signaling. The CAN_TX and CAN_RX pins provide CMOS-level signals compliant with ISO 11898-1, not ISO 11898-2 bus voltage levels.
What development tools support this MCU?
It is fully supported by ModusToolbox™ (v3.1+) and legacy PSoC™ Creator (v4.4). Hardware debugging uses KitProg3 or MiniProg3 programmers. Example projects include CAPSENSE™ tuning, CAN message filtering, and Deep Sleep wakeup with GPIO/CAN interrupt - all available in the Infineon GitHub PDL repository and ModusToolbox™ example browser.
Can CAPSENSE™ operate during Deep Sleep mode?
Yes, CAPSENSE™ CSD hardware operates autonomously in Deep Sleep mode with 2.5 µA total system current. The CSD block can generate interrupts on touch detection without waking the CPU, enabling ultra-low-power wake-on-touch functionality for automotive entry systems and infotainment standby states.
