Product details
Overview
CY8C4246LTI-DM405 from Infineon is a PSoC™ 4200M programmable system-on-chip integrating an Arm® Cortex®-M0 CPU (48 MHz), 128 kB flash, 16 kB SRAM, four opamps with Deep Sleep operation, and dual CAN controllers - enabling mixed-signal embedded control in industrial motor drives and automotive body electronics.
For engineers reviewing the CY8C4246LTI-DM405 datasheet, CY8C4246LTI-DM405 pinout, CY8C4246LTI-DM405 application, or CY8C4246LTI-DM405 equivalent, key selection criteria include CAN bus compatibility, capacitive sensing SNR (>5:1), TCPWM kill-signal triggering, programmable analog routing, and –40°C to +105°C extended temperature operation.
Technical Context
The device implements a reconfigurable architecture combining fixed-function peripherals (dual CAN, eight TCPWM blocks, four SCBs) with programmable analog (four opamps, two comparators, 12-bit SAR ADC @ 1-Msps) and digital logic (four UDBs with 8 macrocells each). All analog blocks retain functionality in Deep Sleep mode at ≤20 nA Stop Mode current.
Its clock system integrates IMO (4–48 MHz), ILO (32.768 kHz), and external crystal support; power management enables Hibernate/Deep Sleep wakeup via GPIO or comparator events, while SmartSense auto-tunes CSD-based capacitive sensing without firmware intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0 @ 48 MHz with single-cycle multiply - enables real-time deterministic control loops in motor and sensor applications. |
| Memory | 128 kB flash (with Read Accelerator) + 16 kB SRAM - supports complex firmware with bootloader, communication stacks, and CAPSENSE™ tuning tables. |
| Analog Peripherals | Four rail-to-rail opamps (Deep Sleep capable), two low-power comparators, 12-bit SAR ADC @ 1-Msps - allows simultaneous signal conditioning, threshold detection, and high-speed sampling. |
| Digital Programmability | Four universal digital blocks (UDBs), each with 8 macrocells and 8-bit datapath - implements custom state machines, glue logic, or protocol accelerators without CPU overhead. |

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 |
|---|---|---|---|
| CY8C4247LTI-DM405 | Same package and core, but with 256 kB flash and 32 kB SRAM - no change in analog/digital peripheral count or CAN capability. | Preferred where firmware size exceeds 128 kB (e.g., dual OTA images, advanced encryption stacks). | Select when future firmware expansion headroom is required without changing board layout or driver software. |
| STM32G474RET6 | Arm Cortex-M4F @ 170 MHz, 512 kB flash, 128 kB SRAM, but lacks integrated CAPSENSE™ and programmable analog/digital logic blocks. | Suitable for high-performance compute tasks but requires external components for capacitive sensing or custom logic. | Choose when floating-point math throughput dominates over analog integration and field-programmable flexibility. |
Compared with CY8C4246LTI-DM405, CY8C4247LTI-DM405 offers scalable memory without altering peripheral functionality, while STM32G474RET6 trades programmable analog/digital reconfigurability for higher CPU performance and larger memory - making the former ideal for hardware reuse and the latter for compute-bound applications.

FAQ
Does CY8C4246LTI-DM405 support CAN FD?
No. This device implements two CAN 2.0B controllers only, with bit rates up to 1 Mbps and standard 11-bit identifier support. It does not include CAN FD features such as flexible data-rate, extended identifiers, or CRC enhancements. For CAN FD, consider Infineon's TRAVEO™ T2G or newer PSoC™ 6 families.
What development tools are required to program CY8C4246LTI-DM405?
PSoC™ Creator IDE is the official tool for schematic-based design, automatic routing, and component configuration. After initial setup, Arm GCC or ARM Compiler v5/v6 can be used for custom C/Verilog builds. Debugging requires a KitProg2/3 or MiniProg4 programmer supporting SWD interface at up to 24 MHz.
Can all 55 GPIOs be used simultaneously for CAPSENSE™?
No. While 55 GPIOs are available, CAPSENSE™ CSD scanning is limited to 32 electrodes per scan group due to hardware resource constraints in the CSD block. Multiple scan groups can be sequenced in firmware, but full parallel sensing across all pins is not supported.
Is the 12-bit SAR ADC capable of simultaneous sampling across multiple channels?
No. The SAR ADC has a single conversion core and supports sequential sampling only. However, its 1-Msps rate and hardware-accelerated scanning with DMA allow sub-10 µs channel-to-channel intervals, effectively approximating simultaneous acquisition for most control-loop applications.
