Product details
Overview
CY8C4547AZQ-S455 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 touch-enabled industrial HMI and motor control systems requiring analog-digital co-processing.
For engineers reviewing the CY8C4547AZQ-S455 datasheet, CY8C4547AZQ-S455 pinout, CY8C4547AZQ-S455 application, or CY8C4547AZQ-S455 equivalent, key selection criteria include Deep Sleep current (2.5 µA), CapSense SNR (>5:1), programmable analog routing, and hardware-accelerated FOC/PFC via MCA block.
Technical Context
The device integrates a 48-MHz Arm Cortex-M0+ CPU with two Divide/Square Root accelerators and an 8-channel DMA engine for deterministic real-time control. Its analog subsystem includes simultaneous-sampling dual SAR ADCs, opamps operable in Deep Sleep, and a capacitance-sensing sigma-delta block supporting SmartSense auto-tuning.
Digital resources comprise five reconfigurable Serial Communication Blocks (SCBs), eight TCPWM modules with quadrature decode and comparator-triggered kill signals, and programmable logic blocks enabling Boolean operations on GPIOs without firmware overhead.

FAQ
Does CY8C4547AZQ-S455 support USB device functionality?
No. The CY8C4547AZQ-S455 does not include a USB PHY or USB controller. Its serial communication is limited to five reconfigurable SCBs supporting I²C, SPI, and UART only. USB connectivity requires external bridge ICs or migration to PSoC™ 6 series devices with native USB support.
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 current of 2.5 µA is specified at 25 °C; at +85 °C, typical Deep Sleep current rises to 4.1 µA per datasheet Section 5.2, with full analog functionality retained across the full range.
Can the dual SAR ADCs perform true simultaneous sampling on all channels?
Yes. Both 12-bit SAR ADCs can sample independently and concurrently. When configured for simultaneous mode, they acquire samples on separate channels at identical timestamps - critical for vector control where phase current and bus voltage must be captured synchronously.
Is CAPSENSE™ firmware included in the device ROM or loaded externally?
CAPSENSE™ firmware is not stored in ROM. It is implemented as a configurable software component within ModusToolbox™ or PSoC™ Creator, compiled into flash alongside application code. The hardware sigma-delta modulator and SmartSense tuning logic are embedded in silicon; only the tuning algorithm and threshold logic reside in firmware.
