Product details
Overview
CY8C4146AZQ-S455 from Infineon Technologies (acquired Cypress Semiconductor) is a 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, CAN 2.0B interface, and programmable analog/digital blocks - deployed in industrial HMI, motor control interfaces, and secure embedded sensors.
For engineers reviewing the CY8C4146AZQ-S455 datasheet, CY8C4146AZQ-S455 pinout, CY8C4146AZQ-S455 application, or CY8C4146AZQ-S455 equivalent, key selection criteria include Deep Sleep current (2.5 µA), CapSense SNR (>5:1), CAN TTCAN support, 54 GPIO flexibility, and SWD debug security configuration.
Technical Context
The device integrates an Arm Cortex-M0+ core with single-cycle multiply, tightly coupled flash accelerator delivering 85% of SRAM access performance, and dual-clock domain operation (HFCLK for peripherals, LFCLK for WCO/RTC). It supports concurrent analog signal acquisition (12-bit SAR ADC, opamps active in Deep Sleep) and digital logic reconfiguration via Smart I/O and TCPWM blocks.
Its clock architecture includes IMO (±2%), ILO (32 kHz), WCO, ECO (4–33 MHz), and PLL - enabling precise timing for CAN bit timing, PWM motor control, and CapSense scanning without external components. The CAN block implements full CAN 2.0B with Time-Triggered CAN (TTCAN) compliance and hardware message filtering.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4147AZQ-S485 | Higher flash (256 KB), same package and peripherals - no additional GPIO or analog resources. | Better suited for firmware with large OTA images or dual-bank bootloaders. | Select when firmware size exceeds 128 KB but no extra peripherals are needed. |
| STM32G071CBT6 | No integrated CapSense or programmable analog; fixed-function peripherals only; lower cost, smaller die. | Lacks hardware-accelerated touch sensing and analog reconfiguration - requires external components for similar functionality. | Choose for cost-sensitive, non-touch applications where fixed peripherals meet requirements. |
Compared with CY8C4146AZQ-S455, CY8C4147AZQ-S485 offers expanded memory headroom without changing footprint or feature set, while STM32G071CBT6 trades programmability and integrated analog for lower BOM cost and simpler toolchain - making it suitable only where CapSense and analog flexibility are not required.

FAQ
What development tools are required to program CY8C4146AZQ-S455?
PSoC Creator IDE (free, Windows-only) is the official development environment, providing schematic-based design entry, automatic routing, and pre-verified components. It generates C code compatible with GCC and Arm Keil toolchains. Debugging uses standard SWD via MiniProg3 or KitProg2 programmers - no proprietary hardware required.
Does CY8C4146AZQ-S455 support CAN FD?
No - the integrated CAN block implements CAN 2.0B with Time-Triggered CAN (TTCAN) extensions only. It does not support CAN FD data rates or extended frame formats. For CAN FD, consider Infineon's newer PSoC 62 or external CAN FD transceivers paired with software-managed protocols.
Can all 54 GPIOs be used simultaneously for CapSense?
No - CapSense requires dedicated analog routing resources and shared CTBm (CapSense Tuning Block) hardware. While any GPIO can be assigned to CapSense, simultaneous use of all 54 pins as independent sensors is limited by CTBm channel count and scan time constraints. Typical designs use ≤32 electrodes with multiplexing.
Is the TRNG NIST SP 800-90A compliant?
Yes - the on-chip True Random Number Generator meets NIST SP 800-90A Annex C requirements for entropy sources and is certified for cryptographic key generation in secure boot and TLS implementations. Output passes FIPS 140-2 statistical tests when configured per Infineon's TRNG application note AN94622.
