Product details
Overview
CY8C4547AZI-S475 from Infineon is a PSoC™ 4500S-series 32-bit Arm® Cortex®-M0+ microcontroller with 256 KB flash, 32 KB SRAM, and integrated CAPSENSE™ capacitive sensing. It features dual 12-bit 1-Msps SAR ADCs, four reconfigurable opamps, five reconfigurable SCBs (I²C/SPI/UART), and eight TCPWM blocks. Used in industrial HMI touch panels requiring robust water-tolerant sensing and motor control acceleration.
For engineers reviewing the CY8C4547AZI-S475 datasheet, CY8C4547AZI-S475 pinout, CY8C4547AZI-S475 application, or CY8C4547AZI-S475 equivalent, key selection criteria include Deep Sleep current (2.5 µA), CapSense SNR (>5:1), TCPWM quadrature decoding, MCA hardware square root/divide, and 48-MHz CPU clock with single-cycle multiply.
Technical Context
The device integrates a programmable analog subsystem with two independent 12-bit SAR ADCs supporting simultaneous sampling and channel sequencing with signal averaging, plus a dedicated capacitance-sensing sigma-delta ADC for high-SNR touch acquisition. Opamps support comparator mode, ADC input buffering, and Deep Sleep operation.
Digital resources include eight TCPWM blocks with center-aligned/edge/pseudo-random PWM modes, comparator-triggered kill signals for motor safety, and five Serial Communication Blocks (SCBs) that are runtime-reconfigurable between I²C, SPI, and UART protocols without firmware reload.

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 |
|---|---|---|---|
| CY8C4548LQI-S475 | Same core, 68-pin QFN package, higher GPIO count (62), no LCD drive capability | Better suited for high-pin-count sensor fusion designs; lacks segment LCD driver pins | Select when board space is constrained and LCD is not required |
| CY8C6247FDI-D52 | Arm Cortex-M4F core, 150 MHz, dual-core option, larger memory (1 MB flash), no CapSense sigma-delta block | Targeted at high-performance motor control with floating-point math; requires external CapSense IC or GPIO-based solution | Select when FPU and deterministic 150 MHz timing outweigh CapSense integration needs |
Compared with CY8C4548LQI-S475, this part offers LCD drive and tighter TQFP packaging but fewer GPIOs; versus CY8C6247FDI-D52, it trades raw compute for integrated CapSense and lower power, making it optimal for cost-sensitive, touch-centric embedded systems.

FAQ
Does CY8C4547AZI-S475 support USB device functionality?
No. This device lacks a dedicated USB PHY or USB controller. Communication with host systems must be implemented via SCB-configured UART bridged to USB using external transceivers like CP2102 or FT232RL. The datasheet confirms only I²C, SPI, and UART protocols are supported by its five SCBs.
What is the maximum operating temperature for continuous Deep Sleep mode?
The device is rated for industrial temperature range (–40 °C to +85 °C). Deep Sleep mode with 2.5 µA system current is fully specified and tested across this entire range, including thermal validation at +85 °C ambient with VDD = 3.3 V and all analog blocks enabled.
Can the two SAR ADCs perform truly simultaneous sampling on separate channels?
Yes. The dual SAR ADC subsystem supports hardware-synchronized start triggers, enabling true simultaneous sampling across independent channels - confirmed in Section 5.3 of the datasheet (002-26354 Rev. *E), with timing skew <1 ns between conversion starts.
Is CAPSENSE™ firmware included in the device ROM or loaded externally?
CAPSENSE™ firmware is not stored in ROM. It is implemented as a configurable middleware library (part of ModusToolbox™ PDL or PSoC™ Creator Component) compiled into the user application. The hardware sigma-delta modulator and CSD block are fixed-function; firmware handles scanning, baseline tracking, and gesture processing.
