Product details
Overview
CY8C4245PVI-DS402T from Infineon Technologies (formerly Cypress) is a 32-bit Arm Cortex-M0 programmable system-on-chip (PSoC 4200DS family) integrating MCU, programmable analog/digital logic, and mixed-signal peripherals. It features 48 MHz CPU, 64 kB flash, 8 kB SRAM, four UDBs, three reconfigurable SCBs, and operates from 1.71–5.5 V - used in embedded sensor hubs and motor control interfaces requiring field-reconfigurable logic.
For engineers reviewing the CY8C4245PVI-DS402T datasheet, CY8C4245PVI-DS402T pinout, CY8C4245PVI-DS402T application, or CY8C4245PVI-DS402T equivalent, key selection criteria include UDB count, TCPWM flexibility, SWD debug support, Deep Sleep current, and GPIO drive configurability across 28-pin SSOP packaging.
Technical Context
The device implements a single-layer AHB-Lite interconnect linking the Cortex-M0 core, flash accelerator, SRAM, and peripheral subsystems. Its clock architecture integrates a trimmable 24–48 MHz IMO (±2% accuracy) and 40 kHz ILO for low-power timing, with six 16-bit dividers supporting fractional baud-rate generation for UART/SPI/I²C.
Digital programmability centers on four universal digital blocks (UDBs), each with 8 macrocells and an 8-bit datapath, enabling user-defined state machines or logic functions synthesized via Verilog or schematic entry in PSoC Creator - complemented by a programmable I/O block (PRGIO) for Boolean operations directly in the signal path.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0, 48 MHz max - enables real-time deterministic execution of firmware with single-cycle multiply for motor control loops. |
| Flash Memory | 64 kB with Read Accelerator - delivers ~85% of SRAM access speed, critical for interrupt latency-sensitive applications. |
| SRAM | 8 kB - sufficient for stack, heap, and peripheral buffers in compact embedded firmware without external memory. |
| Digital Logic | 4 UDBs (8 macrocells each) - supports custom digital logic, PWM sequencers, or protocol engines without FPGA-level complexity. |
| Serial Interfaces | 3 SCBs configurable as I²C/SPI/UART - allows concurrent use of multiple protocols on shared pins via runtime reconfiguration. |
| Power Range | 1.71–5.5 V - supports direct interface with Li-ion batteries, USB VBUS, or industrial 3.3/5 V rails without level-shifting. |
| Debug Interface | 2-wire Serial Wire Debug (SWD) - enables full on-chip debugging in production hardware using standard Arm tools. |
Pinout & Package
Package: 28-pin SSOP (0.635 mm pitch), 11.5 mm × 7.6 mm footprint - compatible with standard surface-mount assembly and legacy PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Primary power supply | Accepts 1.71–5.5 V; powers core, flash, SRAM, and most peripherals - requires local decoupling per datasheet layout guidelines. |
| VSS | Ground reference | System ground return; multiple pins provided to reduce impedance and improve noise immunity in mixed-signal operation. |
| P0[0]–P0[7] | Programmable GPIO port 0 | Configurable as digital input/output, analog input, or serial interface signals (e.g., I²C SDA/SCL) - drive strength and slew rate software-selectable. |
| P1[0]–P1[7] | Programmable GPIO port 1 | Supports comparator inputs, TCPWM outputs, and PRGIO logic - enables hardware-accelerated edge detection or pulse shaping. |
| SWDIO / SWCLK | Debug interface signals | 2-wire SWD interface for programming and full-chip debugging - no JTAG TAP required; uses dedicated pins or multiplexed GPIOs. |
| XRES | External reset input | Active-low asynchronous reset; can be driven by external supervisor IC or pushbutton - overrides internal POR/BOD behavior. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Digital Subsystem | Four UDBs enable field-upgradable logic functions (e.g., custom encoder interfaces or SPI-to-I²C bridges) without hardware changes. |
| Reconfigurable Serial Peripherals | Three SCBs allow dynamic switching between I²C master/slave, SPI master/slave, or UART modes at runtime - reduces BOM count in multi-protocol systems. |
| Deep Sleep Mode with GPIO Wakeup | Sub-1 µA current draw with individual GPIO pin wakeup capability - extends battery life in wireless sensor nodes while retaining responsive wake triggers. |
| Integrated Flash Protection | Hardware-enforced read/write protection and debug disable - prevents unauthorized firmware extraction or reprogramming in secure deployments. |
| On-Chip Clock Calibration | IMO trimming stored in NV memory and adjustable in-field via firmware - maintains timing accuracy across temperature and voltage without external crystal. |
Applications

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 |
|---|---|---|---|
| CY8C4247LQI-BL483 | Same PSoC 4200DS family, but 48-pin QFN package with 36 GPIOs and integrated BLE radio. | Requires Bluetooth connectivity; larger footprint and higher RF design complexity. | Select when wireless telemetry or OTA updates are mandatory - not drop-in compatible due to pinout and RF layout requirements. |
| STM32F072CBT6 | Arm Cortex-M0, 48 MHz, 128 kB flash, 16 kB SRAM, but fixed-function peripherals only - no UDBs or analog programmability. | Lacks field-reconfigurable logic; requires external components for complex timing or protocol adaptation. | Select when cost sensitivity outweighs need for hardware flexibility - best for stable, high-volume designs with static peripheral requirements. |
Compared with CY8C4245PVI-DS402T, CY8C4247LQI-BL483 adds BLE but increases board area and RF validation effort, while STM32F072CBT6 offers more memory but eliminates analog/digital reconfigurability - making CY8C4245PVI-DS402T optimal for space-constrained, function-evolving embedded controllers.

FAQ
Does CY8C4245PVI-DS402T require an external crystal for operation?
No. The device operates from its internal 24–48 MHz IMO oscillator, trimmed to ±2% accuracy and optionally calibrated in-field. An external crystal is optional and only needed if tighter frequency stability (e.g., <±50 ppm) is required for specific communication protocols or timing-critical sampling.
Can the UDBs implement custom communication protocols like 1-Wire or DALI?
Yes. Each UDB provides 8 macrocells and an 8-bit datapath, enabling synthesis of state machines for bit-banged protocols. Cypress-provided Verilog templates and PSoC Creator components support 1-Wire, DALI, and custom UART variants - verified in application notes AN88619 and AN86439.
What debug tools are supported for CY8C4245PVI-DS402T development?
The device supports standard Arm Serial Wire Debug (SWD) via MiniProg3, KitProg2, or third-party tools like Segger J-Link and ST-Link/V2. PSoC Creator IDE provides full integration for programming, breakpoint setting, register inspection, and real-time variable watch - all using the two-wire SWD interface.
Is flash protection reversible after enabling maximum security mode?
No. When device security is fully enabled (debug disabled, flash protection locked), all programming and debug interfaces are permanently disabled. Recovery requires full chip erase - which clears all flash, including protection bits - and reprogramming with new firmware that re-enables debug features if needed.
