Product details
Overview
CY8C4146AZQ-S445 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® sigma-delta capacitive sensing, CAN 2.0B interface, and programmable analog/digital blocks. It targets embedded human-interface, industrial control, and smart sensor applications requiring mixed-signal reconfigurability and low-power operation down to 2.5 µA in Deep Sleep mode.
For engineers reviewing the CY8C4146AZQ-S445 datasheet, CY8C4146AZQ-S445 pinout, CY8C4146AZQ-S445 application, or CY8C4146AZQ-S445 equivalent, key selection criteria include its 54 GPIO count with CapSense support on any pin, CAN 2.0B compliance, 12-bit 1-Msps SAR ADC, TRNG for secure key generation, and compatibility with PSoC Creator IDE for hardware/firmware co-design.
Technical Context
The device integrates an Arm Cortex-M0+ core with tightly coupled flash (128 KB, Read Accelerator) and SRAM (16 KB), enabling deterministic real-time execution at 48 MHz. Its clock architecture combines IMO (±2%), ILO (32 kHz), WCO, ECO (4–33 MHz), and PLL to support precise timing across active and low-power modes.
Analog subsystem includes two opamps (operable in Deep Sleep), a 12-bit SAR ADC with channel sequencer and averaging, two IDACs, two low-power comparators, and a dedicated capacitance-sensing block supporting CSD-based touch with >5:1 SNR and SmartSense™ auto-tuning. Digital resources comprise five reconfigurable SCBs (I²C/SPI/UART), eight TCPWM blocks, and programmable logic for Boolean operations on GPIOs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G071KBT6 | No integrated CapSense or CSD engine; lacks dedicated sigma-delta touch hardware and SmartSense™ tuning | Suitable for general-purpose control but requires external touch controller for robust capacitive UI | Select when CAN + ARM Cortex-M0+ is needed without on-chip touch IP or when leveraging STM32Cube ecosystem |
| MAX32660 | Includes AES-128 and ultra-low-power sleep (1.6 µA), but no CAN peripheral or programmable analog blocks | Better for secure wearable sensors; not viable for automotive or industrial CAN networks | Select when cryptographic acceleration and sub-2 µA sleep dominate over mixed-signal reconfigurability and fieldbus support |
Compared with STM32G071KBT6 and MAX32660, CY8C4146AZQ-S445 uniquely delivers integrated CapSense CSD, CAN 2.0B with TTCAN, and field-programmable analog/digital blocks in a single die-enabling true hardware-software co-design for touch-enabled, connected embedded systems without external ASICs or glue logic.

FAQ
Does CY8C4146AZQ-S445 require an external CAN transceiver?
Yes. The device contains a CAN 2.0B protocol controller but no physical layer (PHY) driver. An external CAN transceiver (e.g., TJA1042, SN65HVD230) must be used to connect to the CAN bus. The CAN_TX and CAN_RX pins provide differential logic-level signals compliant with ISO 11898-1.
Can all 54 GPIOs be used simultaneously for CapSense?
No. While any GPIO pin supports CapSense functionality, the maximum number of simultaneous CapSense sensors depends on the selected scanning method and resource allocation. With CSD, up to 32 buttons/sliders are supported; mutual-capacitance (CSX) mode supports up to 24 × 24 matrix. Pin count does not equal concurrent sensor count due to shared analog routing resources.
What development tools are officially supported for CY8C4146AZQ-S445?
PSoC Creator IDE (v4.4 or later) is the official, free Windows-based toolchain for schematic capture, component configuration, firmware generation, and debug. It fully supports CY8C4146AZQ-S445, including CapSense Tuner, CAN API libraries, and SmartSense™ auto-calibration. Third-party Arm GCC toolchains are compatible via exported Makefiles, but lack GUI-based analog/digital routing and component integration.
Is the TRNG NIST SP 800-90A/B/C compliant?
The TRNG meets the entropy quality and unpredictability requirements defined in NIST SP 800-90A (CTR_DRBG) and SP 800-90C when used with Cypress's certified PSoC 4 TRNG software driver and proper health testing. Certification documentation is provided in AN260177 and the PSoC 4100S Plus TRM Appendix D, covering statistical randomness, backtracking resistance, and prediction resistance.
