Product details
Overview
CY8C4147AZQ-S455 from Infineon Technologies (acquired 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 operates from 1.71–5.5 V and supports Deep Sleep mode with 2.5-μA system current while maintaining opamp and comparator functionality - ideal for low-power industrial HMI and motor control edge nodes.
For engineers reviewing the CY8C4147AZQ-S455 datasheet, CY8C4147AZQ-S455 pinout, CY8C4147AZQ-S455 application, or CY8C4147AZQ-S455 equivalent, key selection criteria include its integrated CAN 2.0B block with Time-Triggered CAN support, 12-bit 1-Msps SAR ADC with sequencer and averaging, dual opamps operational in Deep Sleep, TRNG for secure key generation, and 54 GPIOs with configurable drive modes and CapSense capability on any pin.
Technical Context
The device implements a single-layer AHB-Lite interconnect with dedicated peripheral interconnect (MMIO), enabling concurrent access to flash, SRAM, and peripherals without arbitration bottlenecks. Its clock architecture integrates IMO (±2%), ILO (32 kHz), WCO, ECO (4–33 MHz), and PLL to generate stable 48-MHz HFCLK with fractional/integer dividers for precise peripheral timing.
CapSense v2 uses sigma-delta modulation with hardware-accelerated SmartSense™ auto-tuning and >5:1 SNR, supporting water-tolerant touch interfaces. The CAN block complies with ISO 11898-1:2015 and supports TTCAN for deterministic scheduling in safety-critical motion control loops.
Key Specifications

|---|---|
| CPU Core | Arm Cortex-M0+, 48 MHz, single-cycle multiply - enables real-time control loop execution at ≤20.8 ns/instruction. |
| Flash / SRAM | 128 KB flash with Read Accelerator (≤2 WS @ 48 MHz); 16 KB zero-wait-state SRAM - supports firmware-over-the-air updates and buffer-intensive sensor fusion. |
| Analog Peripherals | 12-bit 1-Msps SAR ADC (differential/single-ended, channel sequencer + signal averaging); two opamps active in Deep Sleep - enables high-resolution current/voltage monitoring during ultra-low-power operation. |
| Digital Peripherals | Five reconfigurable SCBs (I²C/SPI/UART); eight 16-bit TCPWM blocks (center-aligned, quadrature decode, kill-signal triggering) - supports multi-protocol comms and motor gate-drive timing with hardware fault response. |
| Special Functions | CAN 2.0B with TTCAN support; TRNG; CapSense Sigma-Delta with SmartSense™ - provides deterministic fieldbus connectivity, cryptographic key entropy, and robust touch UI without host CPU overhead. |
| Power Modes | Deep Sleep: 2.5 μA (digital) + active analog; Active: 120 μA/MHz - enables battery-powered operation >5 years in sensor node applications with periodic wake-up. |
| GPIO | 54 programmable pins; configurable drive strength (0.5–20 mA), slew rate, and CapSense/analog/digital assignment - eliminates external level shifters and simplifies PCB routing for mixed-signal designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4146AZQ-S423 | Same PSoC 4100S Plus family; 64 KB flash, 8 KB SRAM, no CAN block - lacks TTCAN and CAN PHY support. | Suitable for cost-sensitive CapSense-only HMI where fieldbus connectivity is handled externally. | Select when CAN is unnecessary and BOM cost reduction outweighs firmware scalability needs. |
| STM32G474RET6 | Arm Cortex-M4F @ 170 MHz; 512 KB flash; no integrated CapSense; includes FPU and advanced timers but requires external touch controller. | Better suited for math-intensive motor control (e.g., observer-based FOC) but adds component count and layout complexity for touch UI. | Choose when floating-point computation dominates and capacitive sensing is secondary or implemented via external IC. |
Compared with CY8C4147AZQ-S455, CY8C4146AZQ-S423 reduces memory and removes CAN - limiting use in distributed control networks; STM32G474RET6 offers higher compute throughput but increases bill-of-materials and design effort for touch integration, making CY8C4147AZQ-S455 optimal for integrated HMI + fieldbus edge nodes.

FAQ
Does CY8C4147AZQ-S455 support USB connectivity?
No. This device does not include a USB PHY or USB controller. Communication interfaces are limited to five SCBs (I²C/SPI/UART), CAN 2.0B, and SWD debug. USB functionality requires external bridge ICs such as CY7C65215 or host-side enumeration via UART-to-USB converter.
What is the maximum operating temperature for continuous Deep Sleep mode?
The device is rated for industrial temperature range (–40°C to +85°C). In Deep Sleep mode, junction temperature must remain ≤85°C; thermal performance data shows 2.5-μA system current is maintained up to 85°C ambient with standard PCB copper pour (2 oz, 2-layer).
Can the SAR ADC perform simultaneous sampling across multiple channels?
No. The single SAR ADC supports sequential sampling via hardware channel sequencer with programmable delay between conversions. True simultaneous sampling requires external parallel ADCs; however, the sequencer achieves <100-ns inter-channel skew with averaging enabled for effective multi-sensor correlation.
Is the CAN block compliant with ISO 11898-1:2015?
Yes. The CAN controller implements full CAN 2.0B protocol including extended frame support and TTCAN per ISO/DIS 11898-4. Hardware timestamping resolution is 125 ns, and bit-rate accuracy is ±0.1% at 1 Mbps with external crystal oscillator.
