Product details
Overview
CY8C4247AZA-M485 from Infineon is a PSoC™ 4200M programmable system-on-chip integrating an Arm® Cortex®-M0 CPU (48 MHz), 128 kB flash, 16 kB SRAM, and reconfigurable analog/digital blocks. It delivers capacitive sensing (CSD), LCD drive, CAN communication, and TCPWM control in industrial HMI, motor control, and smart sensor nodes.
For engineers reviewing the CY8C4247AZA-M485 datasheet, CY8C4247AZA-M485 pinout, CY8C4247AZA-M485 application, or CY8C4247AZA-M485 equivalent, key selection criteria include Deep Sleep current (20 nA), SAR ADC performance (12-bit, 1-Msps), opamp count (4, Deep Sleep-capable), and UDB-based digital logic flexibility.
Technical Context
The device implements a tightly coupled MCU subsystem with DMA engine and SROM boot support, enabling deterministic real-time execution. Its analog subsystem includes four rail-to-rail opamps with comparator/ADC buffer modes and two low-power comparators-both operable in Deep Sleep mode with GPIO wakeup capability.
Digital programmability centers on four Universal Digital Blocks (UDBs), each with 8 macrocells and 8-bit datapath, supporting user-defined state machines or Cypress peripheral components. Two independent CAN 2.0B controllers and four reconfigurable SCBs (I²C/SPI/UART) provide robust industrial networking and interface flexibility.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4248LQI-BL553 | Same PSoC™ 4200M family but with Bluetooth LE radio and different package (QFN-80); flash/SRAM identical. | Targets wireless edge nodes requiring BLE connectivity; lacks CAN blocks. | Select when wireless telemetry is required and CAN is not needed. |
| STM32G474RET6 | Arm Cortex-M4F @ 170 MHz, 512 kB flash, 128 kB SRAM; no programmable analog/digital blocks; includes FPU and advanced timers. | Better suited for math-intensive control (e.g., motor FOC) but requires external analog components for sensor conditioning. | Select when floating-point computation dominates and analog programmability is secondary. |
Compared with CY8C4247AZA-M485, CY8C4248LQI-BL553 adds wireless capability at the cost of CAN and higher pin count, while STM32G474RET6 trades analog/digital configurability for raw CPU performance and larger memory-making it less optimal for mixed-signal integration but stronger for compute-bound tasks.

FAQ
Does CY8C4247AZA-M485 support USB device functionality?
No. This part does not include a USB PHY or USB controller. It features four SCBs supporting I²C, SPI, and UART only. For USB connectivity, designers must use external USB-to-UART bridges or select higher-tier PSoC™ devices like the PSoC™ 4100S series with integrated USBFS.
What development tools are required to program CY8C4247AZA-M485?
Infineon's PSoC™ Creator IDE (legacy) or ModusToolbox™ (current) is required for schematic-based design and firmware generation. Programming uses standard Arm Serial Wire Debug (SWD) via KitProg3 or third-party debug probes compliant with Arm CoreSight standards.
Can the SAR ADC sample multiple channels simultaneously?
No. The 12-bit SAR ADC is single-core with a multiplexer; it performs sequential conversions. However, hardware-accelerated scanning with DMA offload enables rapid multi-channel acquisition without CPU intervention-achieving up to 1 Msps aggregate throughput across configured channels.
Is the CAN controller compliant with ISO 11898-1 and ISO 11898-2?
Yes. The two CAN controllers implement full CAN 2.0B protocol with bit rates up to 1 Mbps and support both standard and extended identifiers. Physical layer compliance requires an external ISO 11898-2 transceiver; the MCU handles protocol, filtering, and message RAM management entirely in hardware.
