Product details
Overview
CY8C4548AZQ-S483 from Infineon is a PSoC™ 4500S-based 32-bit Arm® Cortex®-M0+ microcontroller with 256 KB flash, 32 KB SRAM, and integrated CAPSENSE™ capacitive sensing. It features four opamps, two 12-bit 1-Msps SAR ADCs, five reconfigurable Serial Communication Blocks (SCBs), and eight TCPWM blocks. Used in industrial HMI touch panels requiring robust water-tolerant sensing and real-time motor control.
For engineers reviewing the CY8C4548AZQ-S483 datasheet, CY8C4548AZQ-S483 pinout, CY8C4548AZQ-S483 application, or CY8C4548AZQ-S483 equivalent, key selection criteria include Deep Sleep current (2.5 µA), CapSense SNR (>5:1), 48-MHz CPU clock, programmable analog routing, and TQFP-48 package compatibility with standard PCB assembly processes.
Technical Context
The device integrates a single-core Arm Cortex-M0+ CPU with hardware-accelerated divide/square-root units for Field Oriented Control (FOC) and Power Factor Correction (PFC). Its analog subsystem includes dual simultaneous-sampling SAR ADCs, configurable opamp modes (buffer/comparator/ADC input), and low-power comparators operational in Deep Sleep mode.
Digital resources comprise eight TCPWM blocks supporting center-aligned PWM, quadrature decoding, and comparator-triggered kill signals; five SCBs independently configurable as I²C/SPI/UART; and programmable logic blocks enabling Boolean operations on GPIOs without firmware overhead.

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 |
|---|---|---|---|
| CY8C4546AZQ-S483 | Same die, reduced flash (128 KB) and SRAM (16 KB); identical peripherals and pinout | Suitable for cost-sensitive designs with smaller firmware footprint and fewer concurrent tasks | Select when memory requirements fit within 128 KB flash and no future firmware expansion is planned |
| CY8C4547AZQ-S483 | Same die, 256 KB flash but only 16 KB SRAM; otherwise identical analog/digital resources | Preferred for applications needing large code storage but minimal runtime data buffers (e.g., fixed-function sensor hubs) | Choose when firmware size dominates memory needs and DMA-based streaming avoids SRAM bottlenecks |
Compared with CY8C4548AZQ-S483, the CY8C4546AZQ-S483 trades memory capacity for lower cost, while CY8C4547AZQ-S483 retains full flash but halves SRAM-both maintain identical peripheral functionality, timing performance, and CapSense capability in the same TQFP-48 package.

FAQ
Does CY8C4548AZQ-S483 support USB connectivity?
No. This device lacks native USB PHY or controller hardware. Communication relies on its five reconfigurable SCBs operating as UART, SPI, or I²C. External USB-to-UART bridge ICs (e.g., CP2102) are required for USB host interfacing in development or end-product designs.
What debug interfaces does CY8C4548AZQ-S483 provide?
It implements Arm Serial-Wire Debug (SWD) with dedicated SWDCLK and SWDIO pins. Full chip programming, real-time debugging, and trace are supported using MiniProg4 or industry-standard SWD probes-no JTAG adapter or special emulation hardware is needed.
Can the opamps operate during Deep Sleep mode?
Yes. All four opamps can remain powered and functional in Deep Sleep mode, enabling continuous analog signal conditioning (e.g., sensor biasing or filtering) while the CPU and most digital logic are halted to achieve 2.5 µA system current.
Is CAPSENSE™ firmware included with the part?
Infineon provides production-ready CAPSENSE™ middleware as part of ModusToolbox™ and PSoC™ Creator. No separate license or royalty is required-the component library includes auto-tuned firmware, SmartSense configuration tools, and API drivers for immediate integration into application code.
