Product details
Overview
CY8C4247AZI-L433T from Infineon is a 32-bit Arm® Cortex®-M0 microcontroller in the PSoC™ 4200L family, integrating programmable analog (4 opamps, 2 comparators, 12-bit SAR ADC), digital (8 UDBs, 4 SCBs, 2 CAN blocks), and capacitive sensing (CSD) subsystems. It operates from 1.71–5.5 V, delivers 48 MHz CPU performance, and supports Deep Sleep mode with 20-nA current draw. Used in industrial HMI touch panels requiring integrated CAPSENSE™, low-power operation, and on-chip analog signal conditioning.
For engineers reviewing the CY8C4247AZI-L433T datasheet, CY8C4247AZI-L433T pinout, CY8C4247AZI-L433T application, or CY8C4247AZI-L433T equivalent, key selection criteria include its 124-ball VFBGA package, dual CAN interface support, SmartSense™-enabled CSD block, and reconfigurable SCB peripherals for I²C/SPI/UART.
Technical Context
The device implements an Arm® Cortex®-M0 core with single-cycle multiply and a dedicated DMA engine (32 channels) for offloading peripheral data movement. Its analog subsystem includes four CTBm opamps supporting comparator mode and ADC input buffering, plus two independent low-power comparators that remain active in Deep Sleep.
Digital flexibility stems from eight Universal Digital Blocks (UDBs), each with 8 macrocells and an 8-bit datapath, enabling custom logic synthesis. Four Serial Communication Blocks (SCBs) are runtime-reconfigurable as I²C, SPI, or UART, and two fixed-function CAN 2.0B controllers support industrial networking with bit-rate up to 1 Mbps.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4248LQI-BL483 | Same PSoC™ 4200L core but 68-pin QFN package (vs. 124-ball VFBGA); 128 kB flash (vs. 256 kB); no USB interface. | Lacks USB and has lower flash capacity - suitable for cost-sensitive CAN-only nodes without host connectivity. | Select when board layout requires QFN, USB is unnecessary, and firmware size < 128 kB. |
| STM32G474RET6 | Arm® Cortex®-M4F core (170 MHz), 512 kB flash, 128 kB SRAM, but no programmable analog/digital fabric or CAPSENSE™. | Requires external components for touch sensing and analog signal chain - increases BOM and layout complexity for HMI designs. | Select when floating-point math, higher CPU throughput, or DSP acceleration is required over integrated analog configurability. |
Compared with CY8C4247AZI-L433T, CY8C4248LQI-BL483 trades USB and memory for smaller footprint and lower cost, while STM32G474RET6 offers superior compute but lacks hardware-accelerated capacitive sensing and analog reconfiguration - making it less optimal for touch-centric embedded systems.

FAQ
Does CY8C4247AZI-L433T support USB device enumeration without external PHY?
Yes. The part integrates a full-speed USB 2.0 device controller with on-die transceivers and Battery Charger Detect (BCD) logic compliant with USB-IF BC 1.2. No external PHY or level-shifting components are required for standard USB device operation at 12 Mbps.
What is the maximum operating temperature rating for this device?
CY8C4247AZI-L433T is rated for industrial temperature range: –40 °C to +85 °C. This is confirmed in Section 5.2.1 of the official Infineon datasheet (001-91686 Rev. *L), where DC and AC electrical specifications are guaranteed across this ambient temperature range.
Can the two CAN controllers operate simultaneously on separate buses?
Yes. The device contains two independent CAN 2.0B controllers (CAN0 and CAN1), each with dedicated TX/RX pins, message RAM, and filter units. They operate concurrently with no resource contention, enabling gateway functionality between two isolated CAN networks.
Is SmartSense™ tuning supported in PSoC™ Creator v4.4 and later?
Yes. SmartSense™ auto-tuning is fully supported in PSoC™ Creator v4.4+ via the CAPSENSE™ CSD Component. The tool automatically generates firmware for baseline tracking, noise threshold adaptation, and finger capacitance compensation without manual register programming.
