Product details
Overview
CY8C4245LTI-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, and reconfigurable analog/digital blocks. It supports capacitive sensing (CSD), LCD segment drive, CAN communication, and TCPWM for motor control in industrial HMI and embedded sensor systems.
For engineers reviewing the CY8C4245LTI-DM405 datasheet, CY8C4245LTI-DM405 pinout, CY8C4245LTI-DM405 application, or CY8C4245LTI-DM405 equivalent, key selection criteria include Deep Sleep current (20 nA), SAR ADC performance (12-bit, 1-Msps), opamp count (4), UDB programmability, and CAN block integration for deterministic industrial networking.
Technical Context
The device implements a dual-domain architecture: a fixed-function Arm® Cortex®-M0 subsystem with DMA and memory management coexists with fully reconfigurable analog (opamps, comparators, IDACs, CSD) and digital (UDBs, TCPWM, SCBs) resources. Clocking includes IMO (48 MHz), ILO (32.768 kHz), and crystal oscillator support for precision timing.
Its programmable interconnect enables runtime reconfiguration of peripherals - e.g., serial communication blocks (SCBs) can be dynamically assigned as I²C, SPI, or UART; TCPWM blocks support center-aligned PWM with comparator-triggered kill signals for motor safety; and CSD hardware delivers >5:1 SNR with SmartSense auto-tuning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0 @ 48 MHz with single-cycle multiply - enables real-time control loops and firmware-based signal processing without external DSP. |
| Memory | 128 kB flash (with Read Accelerator) + 16 kB SRAM - sufficient for complex HMI firmware, sensor fusion algorithms, and bootloader storage. |
| Analog Peripherals | 4 opamps (Deep Sleep capable), 2 low-power comparators, 12-bit SAR ADC (1-Msps), 4 IDACs - supports simultaneous analog front-end conditioning, capacitive sensing, and precision measurement. |
| Digital Programmability | 4 Universal Digital Blocks (UDBs), each with 8 macrocells + 8-bit datapath - allows custom state machines, protocol engines, or glue logic without FPGA-level complexity. |
| Communication | 4 SCBs (reconfigurable I²C/SPI/UART) + 2 CAN 2.0B controllers - enables multi-protocol connectivity and robust fieldbus integration in industrial nodes. |
| Power Management | 20 nA Stop Mode with GPIO wakeup, Deep Sleep with analog active - extends battery life in portable HMIs while retaining sensor responsiveness. |
| Capacitive Sensing | Infineon CSD engine with >5:1 SNR and water tolerance - delivers reliable touch button/slider operation in harsh or wet environments. |
Pinout & Package
This device is packaged in a 44-pin TQFP (7 mm × 7 mm, 0.8 mm pitch) with 38 GPIOs supporting CAPSENSE™, LCD, analog, or digital functions. Drive modes, slew rates, and output strengths are fully programmable per pin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Supports 1.71–5.5 V operation; decoupling required per datasheet layout guidelines to ensure analog stability and low-noise Deep Sleep. |
| P0[0]–P0[7], P1[0]–P1[7], P2[0]–P2[7], P3[0]–P3[7], P4[0]–P4[7], P5[0]–P5[7] | Programmable GPIO | 38 pins configurable as analog inputs/outputs, digital I/O, CAPSENSE™ electrodes, LCD segments/commons, or SCB/CAN signal lines. |
| XRES | External reset input | Active-low asynchronous reset; internal pull-up ensures reliable startup without external components unless extended debounce is needed. |
| SWDCLK / SWDIO | Debug interface | Two-pin Serial Wire Debug (SWD) for programming and real-time debugging; no dedicated JTAG pins required. |
| XTAL_IN / XTAL_OUT | Clock crystal connection | Supports external 1–33 MHz crystals for high-accuracy timing; optional for applications using IMO/ILO only. |
Key Features
| Feature | Design Value |
|---|---|
| Reconfigurable UDBs | Four independent universal digital blocks enable custom peripheral implementation (e.g., encoder interfaces, pulse generators, or protocol translators) without silicon change. |
| SmartSense™ Auto-Tuning | Hardware-accelerated calibration of CAPSENSE™ parameters eliminates manual tuning and maintains stable touch performance across temperature/humidity variations. |
| Deep Sleep Analog Operation | Opamps and comparators remain functional at ≤1 µA total current - enables always-on capacitive wake detection or low-power sensor monitoring. |
| LCD Direct Drive | All GPIOs support LCD segment/common drive with 4-bit memory per pin - eliminates external LCD drivers in small-segment displays (e.g., 4×32 segments). |
| Kill Signal Integration | TCPWM blocks accept comparator outputs as hardware-triggered kill inputs - provides sub-microsecond fault response for motor gate drivers and safety-critical PWM. |
Applications
| Industrial HMI Panels | Motor Control Nodes |
|---|---|
|
Use Scenario: Touch-enabled operator interface on PLC-mounted panels with segmented LCD display and environmental sealing. IC Role / Device Role / Timing Role: System controller managing CAPSENSE™ buttons, LCD refresh, CAN bus messaging, and local diagnostics.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable 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 block count or peripheral configuration. | Required when firmware size exceeds 128 kB or additional RAM is needed for buffering or RTOS stacks. | Select if future firmware growth or larger algorithm footprint is anticipated; otherwise, DM405 offers optimal cost/performance balance. |
| STM32F072RBT6 | Arm Cortex-M0 @ 48 MHz, 128 kB flash, 16 kB SRAM, but lacks integrated CAPSENSE™, UDBs, and LCD drive - requires external components for equivalent functionality. | Suitable for simpler control tasks without capacitive sensing or programmable logic; not viable for direct CSD/LCD integration. | Choose only when design already uses discrete touch/LCD solutions and prioritizes broad ecosystem/toolchain over integration density. |
Compared with CY8C4245LTI-DM405, the CY8C4247LTI-DM405 offers headroom for firmware expansion without architectural change, while the STM32F072RBT6 trades integration for broader third-party tool support - making DM405 optimal for designs requiring embedded analog programmability and ultra-low-power touch.

FAQ
Does CY8C4245LTI-DM405 support CAN FD?
No. The device integrates two CAN 2.0B controllers compliant with ISO 11898-1, supporting up to 1 Mbps classical CAN only. CAN FD frame format, higher data rates, and extended arbitration fields are not implemented in the PSoC™ 4200M series hardware.
What development tools are required to program this device?
PSoC™ Creator IDE (legacy) or ModusToolbox™ (current) is required for schematic-based design and code generation. Both support automatic routing of analog/digital resources and provide APIs for all peripherals. Programming is performed via SWD using MiniProg3, KitProg3, or compatible debug probes.
Can all GPIO pins drive LCD segments in Deep Sleep mode?
Yes. All GPIOs support LCD segment/common drive with 4-bit memory retention during Deep Sleep, enabling static segment updates without CPU intervention. Segment voltage levels and bias control are managed by the dedicated LCD block, independent of CPU state.
Is the 12-bit SAR ADC usable simultaneously with CAPSENSE™ operation?
Yes. The SAR ADC and CSD subsystem operate on separate analog routing paths and clock domains. Concurrent use is supported - for example, measuring temperature via ADC while running touch scanning - provided proper resource allocation and timing constraints are observed in PSoC™ Creator.
