Product details
Overview
CY8C4247AZQ-M485T 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 supports capacitive sensing (CSD), segment LCD drive, dual CAN, and TCPWM for motor control in industrial HMI and automotive body electronics.
For engineers reviewing the CY8C4247AZQ-M485T datasheet, CY8C4247AZQ-M485T pinout, CY8C4247AZQ-M485T application, or CY8C4247AZQ-M485T equivalent, key selection criteria include Deep Sleep current (20 nA), CSD SNR (>5:1), TCPWM kill-signal triggering, and 68-pin QFN package compatibility with GPIO-driven CAPSENSE™ and LCD segments.
Technical Context
The device implements a tightly coupled MCU subsystem with DMA-accelerated data movement between SRAM, peripherals, and flash. Its programmable analog includes four opamps operable in Deep Sleep mode with ADC input buffering and comparator modes, plus two low-power comparators and a 12-bit SAR ADC (1 Msps).
Digital flexibility stems from four Universal Digital Blocks (UDBs), each with 8 macrocells and an 8-bit datapath, enabling user-defined state machines or Verilog-based logic. Four reconfigurable SCBs support runtime I²C/SPI/UART switching, while two independent CAN controllers meet ISO 11898-1 requirements for industrial networking.

FAQ
Does CY8C4247AZQ-M485T support JTAG debugging?
No. This device uses Serial Wire Debug (SWD) only, implemented on dedicated SWDCLK and SWDIO pins. JTAG is not supported due to silicon-level configuration of the debug interface; SWD provides equivalent programming, breakpoint, and trace capabilities with reduced pin count and lower EMI.
What is the maximum operating frequency of the SAR ADC?
The 12-bit SAR ADC achieves a maximum conversion rate of 1 Msps under typical conditions with AVDD = 3.3 V and reference voltage = 1.2 V. Full-speed operation requires proper decoupling of AVDD and reference pins, and clock source stability must be maintained within ±1% to avoid missing codes.
Can all GPIO pins drive LCD segments in Deep Sleep mode?
Yes. All 55 GPIO pins support LCD segment or common drive in Deep Sleep mode with 4-bit memory retention per pin. The LCD controller maintains segment state autonomously without CPU intervention, consuming <1 µA total while refreshing up to 240 segments at 60 Hz.
Is the CAN peripheral compliant with ISO 11898-1 and ISO 11898-2?
The CAN controller implements ISO 11898-1 (data link layer) fully, including bit timing, error framing, and arbitration. Physical layer compliance (ISO 11898-2) requires an external CAN transceiver; the CY8C4247AZQ-M485T provides TX/RX signals compatible with industry-standard transceivers such as TJA1042 or SN65HVD230.
