Product details
Overview
CY8C4247AZI-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 configurable analog/digital peripherals including four opamps, two comparators, a 12-bit 1-Msps SAR ADC, four IDACs, and eight TCPWM blocks - deployed in industrial HMI, capacitive touch interfaces, and low-power sensor nodes.
For engineers reviewing the CY8C4247AZI-M485 datasheet, CY8C4247AZI-M485 pinout, CY8C4247AZI-M485 application, or CY8C4247AZI-M485 equivalent, key selection criteria include Deep Sleep current (20 nA), CAPSENSE™ SNR (>5:1), reconfigurable SCBs (I²C/SPI/UART), CAN dual-block support, and 68-pin QFN package compatibility with up to 55 GPIOs.
Technical Context
The device implements a tightly coupled MCU subsystem with DMA engine and SROM-based boot code, enabling deterministic real-time execution. Its analog subsystem features opamps operable in Deep Sleep mode with ADC input buffering and comparator modes, plus CSD-based capacitive sensing with hardware-accelerated SmartSense tuning.
Digital flexibility stems from four Universal Digital Blocks (UDBs), each with 8 macrocells and 8-bit datapath, supporting user-defined state machines or Verilog logic. Two independent CAN 2.0B controllers and four runtime-reconfigurable SCBs provide protocol agility for industrial networking and peripheral interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0 @ 48 MHz with single-cycle multiply - enables real-time control loops without software multiplication overhead. |
| Memory | 128 kB flash + 16 kB SRAM - sufficient for firmware, capacitive sensing algorithms, and communication stacks with over-the-air update headroom. |
| ADC | 12-bit SAR ADC @ 1 Msps - supports high-resolution sensor acquisition (e.g., temperature, pressure) with minimal sampling latency. |
| Low-Power Modes | 20 nA Stop Mode with GPIO wakeup - extends battery life in always-on touch or monitoring applications requiring sub-μA quiescent current. |
| CAPSENSE™ | Capacitive Sigma-Delta (CSD) with >5:1 SNR and water tolerance - delivers robust touch performance on curved or sealed front panels. |
| CAN Interface | Two independent CAN 2.0B controllers - enables dual-bus automotive diagnostics or industrial fieldbus redundancy without external transceivers. |
| GPIO Count | Up to 55 programmable pins - supports mixed-signal routing for LCD segment drive, analog sensing, digital I/O, and CAPSENSE™ electrodes simultaneously. |
Pinout & Package
Package: 68-pin QFN (10 mm × 10 mm, 0.5 mm pitch), RoHS-compliant, thermally enhanced for industrial ambient operation (–40°C to +105°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO3 | I/O Power Supply | Independent 1.71–5.5 V domains per port group - allows mixed-voltage interfacing (e.g., 3.3 V MCU core with 5 V display interface). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4248LQI-BL553 | Same PSoC™ 4200M architecture but with 256 kB flash, 32 kB SRAM, and Bluetooth LE radio integrated - no external RF module required. | Targeted at wireless-connected devices; lacks CAN blocks and has higher active current (120 μA/MHz vs. 95 μA/MHz). | Select when BLE connectivity and larger firmware storage outweigh CAN requirement and ultra-low Deep Sleep current. |
| STM32G071CBT6 | Arm® Cortex®-M0+ core @ 64 MHz, 128 kB flash, 36 kB SRAM, but no programmable analog/digital fabric - fixed-function peripherals only. | Suitable for deterministic control tasks but requires external components for CAPSENSE™, LCD drive, or flexible analog signal chains. | Select when cost-sensitive, high-volume applications prioritize toolchain familiarity and don't require hardware-reconfigurable analog or digital logic. |
Compared with CY8C4247AZI-M485, CY8C4248LQI-BL553 adds wireless capability at the expense of CAN and higher power, while STM32G071CBT6 trades configurability for lower unit cost and simpler validation - making CY8C4247AZI-M485 optimal for mixed-signal systems demanding hardware-level flexibility without RF.

FAQ
Does CY8C4247AZI-M485 support CAN FD?
No. CY8C4247AZI-M485 integrates two CAN 2.0B controllers compliant with ISO 11898-1:2003, supporting up to 1 Mbps bit rate and standard/extended frame formats. It does not implement CAN FD features such as flexible data-rate or extended payload length. For CAN FD, consider Infineon's TRAVEO™ T2G or newer PSoC™ 6 families.
What development tools are required for CAPSENSE™ tuning?
Infineon's PSoC™ Creator IDE (legacy) or ModusToolbox™ (current) is required, both providing the CAPSENSE™ Tuner utility. This GUI tool connects via KitProg3 to perform real-time parameter adjustment, noise analysis, and SmartSense auto-tuning - no oscilloscope or external test equipment needed for baseline calibration.
Can the 12-bit SAR ADC measure signals beyond VDDIO?
No. The SAR ADC input range is rail-to-rail relative to its selected reference (Vref or VDDA), with absolute maximum input voltage limited to VDDIO + 0.3 V. To measure higher-voltage signals, external resistive dividers or opamp level-shifting circuits must be used - the internal programmable opamps can serve this function with appropriate gain configuration.
Is the 68-pin QFN package lead-free and RoHS-compliant?
Yes. CY8C4247AZI-M485 uses a lead-free, halogen-free, RoHS-compliant 68-pin QFN package (10 mm × 10 mm, 0.5 mm pitch) with NiPdAu terminal finish. It meets JEDEC J-STD-020 moisture sensitivity level 3 and supports standard reflow profiles up to 260°C peak temperature.
