Product details
Overview
CY8C4146AZI-S443 from Infineon is a 32-bit Arm® Cortex®-M0+ programmable system-on-chip (PSoC™ 4100S Plus) with 128 KB flash, 16 KB SRAM, and integrated CAPSENSE™ capacitive sensing. It features eight 16-bit TCPWM blocks, five reconfigurable serial communication blocks (SCB), and a CAN 2.0B controller supporting TTCAN-used in industrial HMI, motor control interfaces, and smart appliance touch panels.
For engineers reviewing the CY8C4146AZI-S443 datasheet, CY8C4146AZI-S443 pinout, CY8C4146AZI-S443 application, or CY8C4146AZI-S443 equivalent, key selection criteria include Deep Sleep current (2.5 µA), 48 MHz CPU clock, 1-Msps 12-bit SAR ADC, CAPSENSE™ SNR (>5:1), and 44-pin TQFP package compatibility with hardware tuning via SmartSense.
Technical Context
The device integrates a single-core Arm® Cortex®-M0+ CPU running at up to 48 MHz with single-cycle multiply, supported by PLL-based clock generation and multiple low-power oscillators (IMO, ILO, WCO, ECO). Memory subsystem includes 128 KB flash with read accelerator and 16 KB SRAM, managed by an 8-channel DMA engine.
Analog resources comprise two opamps (Deep Sleep-capable), a 12-bit 1-Msps SAR ADC with channel sequencer and averaging, dual IDACs, two low-power comparators, and a dedicated capacitance-sensing block enabling sigma-delta (CSD) operation with >5:1 SNR and water-tolerant touch detection.

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-S473 | Same PSoC™ 4100S Plus family; 128 KB flash, 16 KB SRAM, but 48-pin TQFP (0.5 mm pitch) and higher GPIO count (54) | Requires finer-pitch PCB layout; better suited for designs needing more analog/digital I/O or LCD segment drive | Select when additional GPIOs or tighter board space justifies 0.5 mm pitch assembly complexity |
| CY8C4046LQI-S412 | Lower-tier PSoC™ 4000S: 32 KB flash, 4 KB SRAM, no CAN block, no TRNG, 12-bit SAR ADC only (no IDACs/opamps) | Lacks CAPSENSE™ SNR optimization, TTCAN, and analog flexibility - limited to basic touch + UART/I²C control | Choose for cost-sensitive, non-safety-critical touch-only applications without motor or network requirements |
Compared with CY8C4147AZI-S473, this part offers identical core peripherals in a more manufacturable 0.8 mm pitch package; versus CY8C4046LQI-S412, it adds CAN, TRNG, dual opamps, and SmartSense-critical for industrial reliability and security.

FAQ
Does CY8C4146AZI-S443 support JTAG debugging?
No. This device uses Arm® Serial Wire Debug (SWD) exclusively-SWDCLK and SWDIO pins provide full programming, breakpoint, and trace capability. JTAG is not implemented; SWD offers equivalent debug functionality with fewer pins and lower overhead in production systems.
What is the maximum operating temperature for CY8C4146AZI-S443?
The CY8C4146AZI-S443 is rated for industrial temperature range: –40 °C to +85 °C ambient. Its internal voltage regulators and flash memory retain full specification compliance across this range, validated per JEDEC JESD22-A104.
Can CAPSENSE™ operate while the CPU is in Deep Sleep mode?
Yes. CAPSENSE™ hardware-including CSD sensing engine and SmartSense auto-calibration-remains fully active during Deep Sleep mode. The CPU wakes only upon valid touch interrupt, maintaining 2.5 µA system current while preserving touch responsiveness.
Is the CAN controller compatible with ISO 11898-1:2015 physical layer?
No. The on-chip CAN 2.0B block implements the protocol layer only. External CAN transceiver (e.g., TJA1042T/3) compliant with ISO 11898-1:2015 must be used for physical layer signaling, termination, and bus fault protection.
