Product details
Overview
CY8C4146AZI-S455 from 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. It targets embedded human-interface, industrial control, and IoT edge nodes requiring low-power operation (2.5 µA Deep Sleep), high SNR touch sensing (>5:1), and hardware-accelerated cryptography via TRNG.
For engineers reviewing the CY8C4146AZI-S455 datasheet, CY8C4146AZI-S455 pinout, CY8C4146AZI-S455 application, or CY8C4146AZI-S455 equivalent, key selection criteria include its 54-GPIO TQFP-44 package, dual opamp + 12-bit SAR ADC + 8× TCPWM timing subsystem, CAN 2.0B block with TTCAN support, and Deep Sleep–capable analog peripherals for battery-powered sensing systems.
Technical Context
The device integrates a single-layer AHB-Lite interconnect linking CPU, SRAM, flash, and peripherals including five reconfigurable Serial Communication Blocks (SCBs) supporting I²C/SPI/UART, and a dedicated CAN 2.0B controller with Time-Triggered CAN capability. Clocking is managed by IMO (±2%), ILO (32 kHz), WCO, ECO (4–33 MHz), and PLL-enabling precise timing across sleep modes.
Analog subsystem includes two rail-to-rail opamps operable in Deep Sleep, a 12-bit 1-Msps SAR ADC with channel sequencer and averaging, two IDACs, and two low-power comparators-all accessible on any GPIO. Digital logic uses Smart I/O and programmable logic blocks for Boolean operations without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4147AZI-S475 | Same PSoC 4100S Plus family; 256 KB flash, 32 KB SRAM, identical peripherals and pinout - higher memory variant. | Required when firmware exceeds 128 KB or needs larger RAM buffers for protocol stacks or audio processing. | Select if future firmware growth or multi-protocol support (e.g., BLE + CAN) demands expanded memory headroom. |
| STM32L476RG | Arm Cortex-M4F @ 80 MHz, 1 MB flash, 128 KB SRAM, no integrated CapSense or CAN FD - lacks programmable analog/digital fabric. | Suitable for general-purpose ultra-low-power MCU use but requires external touch controller and CAN transceiver. | Choose only when design prioritizes raw CPU performance and memory over integrated mixed-signal flexibility and rapid touch development. |
Compared with CY8C4146AZI-S455, CY8C4147AZI-S475 offers scalable memory within identical architecture and footprint, while STM32L476RG trades programmable analog/digital blocks for higher CPU throughput and larger memory - making it less suitable for CapSense-centric or hardware-accelerated mixed-signal designs.

FAQ
What development tools are required to program and debug CY8C4146AZI-S455?
PSoC Creator IDE (free Windows-based tool) is the primary development environment, providing schematic-based hardware configuration, API-driven firmware generation, and integrated SWD debugging. It supports drag-and-drop peripheral placement, automatic routing, and component-level simulation. Third-party Arm GCC toolchains and debuggers (e.g., Segger J-Link) are also compatible via standard SWD interface.
Does CY8C4146AZI-S455 support USB connectivity?
No, CY8C4146AZI-S455 does not include a USB PHY or USB controller. Its five SCBs support only I²C, SPI, and UART protocols. For USB host/device functionality, an external USB bridge IC (e.g., CY7C65215) or migration to PSoC 4000S/4100S+ variants with USBFS is required.
Can the CapSense functionality operate during Deep Sleep mode?
Yes - CapSense CSD scanning can run autonomously in Deep Sleep mode using the internal low-power oscillator (ILO) and dedicated hardware sequencer. The CPU remains powered down while CapSense logic, IDACs, and analog front-end remain active, achieving typical current draw of 2.5 µA with periodic touch polling.
Is the CAN interface compliant with ISO 11898-1 and ISO 11898-2 standards?
The CY8C4146AZI-S455 implements the CAN 2.0B protocol controller per ISO 11898-1, including TTCAN extensions. However, it does not integrate a physical layer transceiver - compliance with ISO 11898-2 requires an external CAN transceiver (e.g., TJA1042T/3) connected to CAN_TX/CAN_RX pins and properly terminated.
