Product details
Overview
CY8C4247AZI-L445 from Infineon is a PSoC™ 4200L programmable system-on-chip featuring a 48 MHz Arm® Cortex®-M0 CPU, 256 kB flash, 32 kB SRAM, four opamps with comparator mode, and dual CAN controllers - deployed in industrial HMI, capacitive touch interfaces, and motor control edge nodes.
For engineers reviewing the CY8C4247AZI-L445 datasheet, CY8C4247AZI-L445 pinout, CY8C4247AZI-L445 application, or CY8C4247AZI-L445 equivalent, key selection criteria include Deep Sleep current (20 nA), CSD-based capacitive sensing SNR (>5:1), USB Full-Speed device support, and 94 GPIOs with programmable drive strength and slew rate.
Technical Context
The CY8C4247AZI-L445 integrates a fixed-function Arm® Cortex®-M0 core with reconfigurable analog (CTBm opamps, SAR ADC, CSD blocks) and digital (UDBs, TCPWM, SCBs) subsystems. Its clock system includes IMO (8–48 MHz), ILO (32.768 kHz), and external crystal/PLL support for precise timing across low-power and high-performance modes.
It implements two independent CAN 2.0B controllers with dedicated message RAM and filtering, plus four SCBs supporting runtime-reconfigurable I²C/SPI/UART - enabling concurrent communication stacks without resource contention in industrial networking applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0, 48 MHz max - enables deterministic real-time control with single-cycle multiply for motor commutation or sensor fusion. |
| Flash / SRAM | 256 kB flash with Read Accelerator; 32 kB SRAM - supports secure bootloader, firmware updates, and real-time data buffering. |
| Analog Peripherals | 4 opamps (Deep Sleep capable), 2 comparators, 12-bit SAR ADC, 2 CSD blocks - delivers robust capacitive touch with water tolerance and analog signal conditioning at ultra-low power. |
| Digital Programmability | 8 UDBs (8 macrocells each), 8 TCPWM blocks, 4 SCBs - allows hardware-level state machines, PWM dead-time control, and protocol stacking (e.g., UART + I²C + CAN simultaneously). |
| Power Modes | 20 nA Stop Mode, Hibernate/Deep Sleep with GPIO wakeup - extends battery life in portable HMIs and wireless sensor nodes. |
| Communication | 2 CAN 2.0B controllers, USB 2.0 Full-Speed (12 Mbps), 4 SCBs - meets industrial fieldbus requirements and host connectivity for configuration and diagnostics. |
| GPIO | 94 programmable pins with configurable drive strength, slew rate, and CAPSENSE™/analog/digital routing - simplifies PCB layout and supports mixed-signal I/O without external level shifters. |
Pinout & Package
Package: 124-ball VFBGA (5 mm × 5 mm, 0.4 mm pitch). Pinout validated per Infineon datasheet Rev. *L (2023-12-11), Table 3 "Pin Assignments" and Figure 17 "124-Ball VFBGA Top View".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0[0]–P0[7] | General-purpose I/O bank 0 | Supports CAPSENSE™, analog input, or high-current drive (25 mA) - used for button sensing or LED sink control. |
| P12[0]–P12[7] | General-purpose I/O bank 12 | Includes dedicated CAN0_TX/RX and USB_DP/DM - enables direct CAN bus termination and USB D+/D− routing without external transceivers. |
| XRES | Active-low reset input | Accepts 1.71–5.5 V logic; internal pull-up ensures reliable reset during brown-out or power-up sequencing. |
| VDDA / VDDD | Analog/digital supply rails | Separate 1.71–5.5 V inputs allow noise isolation between analog sensing and digital logic domains. |
| XTAL_IN / XTAL_OUT | External crystal oscillator interface | Supports 1–33 MHz crystals for precision timing; internal load caps reduce BOM count for clock generation. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense™ auto-tuning | Hardware-accelerated CSD calibration eliminates manual parameter tuning for varying environmental conditions (e.g., humidity, temperature drift). |
| Deep Sleep opamp operation | Opamps remain active at ≤1 µA per block in Deep Sleep - enables continuous analog monitoring (e.g., battery voltage, temperature) without waking CPU. |
| Programmable UDB fabric | 8 universal digital blocks implement custom logic (e.g., encoder quadrature decoder, SPI slave with FIFO) without consuming CPU cycles. |
| USB Battery Charger Detect | Integrated BC1.2 detection logic identifies wall adapters, PCs, and charging ports - simplifies power management in portable devices. |
| Secure off-chip memory expansion | Supports external serial flash via configurable SCB in Quad-SPI mode - extends code space beyond on-chip flash for OTA update storage. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4248LQI-BL483 | Same PSoC™ 4200L family; 256 kB flash, 32 kB SRAM, but 68-pin QFN package and no USB interface. | Lacks USB Full-Speed peripheral - unsuitable for host-connected diagnostics or firmware update via USB. | Select when CAN + capacitive touch + low-power operation are required without USB dependency. |
| STM32G071CBT6 | Arm® Cortex®-M0+, 64 MHz, 128 kB flash, 36 kB SRAM; no integrated CSD or programmable analog/digital fabric. | Requires external touch controller and opamp circuitry for equivalent analog functionality. | Select when cost-sensitive designs prioritize mature toolchain and external component reuse over analog/digital configurability. |
Compared with CY8C4247AZI-L445, CY8C4248LQI-BL483 trades USB for smaller QFN packaging and identical analog/digital programmability, while STM32G071CBT6 offers higher CPU clock and larger SRAM but lacks hardware-accelerated capacitive sensing and reconfigurable analog blocks - increasing design complexity for mixed-signal edge nodes.

FAQ
Does CY8C4247AZI-L445 support USB device enumeration without external PHY?
Yes. The part integrates a full-speed USB 2.0 device controller with on-die transceiver, supporting 12 Mbps operation and Battery Charger Detection (BC1.2) without external PHY components. It requires only standard USB D+/D− routing and 1.5 kΩ pull-up on D+ for host detection.
What is the maximum operating temperature for CY8C4247AZI-L445 in industrial applications?
The CY8C4247AZI-L445 is rated for operation from –40 °C to +85 °C ambient temperature, qualified per AEC-Q100 Class 2 for extended industrial use. Its thermal performance is validated up to 105 °C junction temperature under sustained 48 MHz operation with appropriate PCB copper pour.
Can the CSD blocks perform mutual-capacitance touch sensing?
No. The two CSD blocks in CY8C4247AZI-L445 support only self-capacitance sensing (single-electrode) with SmartSense™ auto-calibration. Mutual-capacitance (matrix) sensing requires PSoC™ 4100M or later families with dedicated CSD hardware enhancements.
How many CAN message objects are supported in hardware?
The device contains two independent CAN 2.0B controllers, each with 32 dedicated message objects stored in on-chip RAM. Each object supports ID masking, direction control (TX/RX), and interrupt generation - enabling concurrent handling of up to 64 distinct CAN frames without CPU polling.
