It supports up to 68 GPIOs with programmable analog and digital blocks, and operates across -40°C to 85°C industrial temperature range. Used in human-machine interface (HMI) systems requiring robust touch control and real-time sensor processing.
For engineers reviewing the CY8C4248FNI-BL583T datasheet, CY8C4248FNI-BL583T pinout, CY8C4248FNI-BL583T application, or CY8C4248FNI-BL583T equivalent, key selection criteria include CapSense™ channel count, flash/SRAM size, USB 2.0 device support, and QFN-68 package compatibility for space-constrained HMI designs.
Technical Context
This device integrates a 48 MHz Arm® Cortex®-M0+ core with dedicated hardware accelerators for CapSense™, enabling low-latency touch detection without CPU overhead. It includes a programmable analog subsystem with op-amps, comparators, and ADCs, plus a digital routing fabric supporting custom logic and state machines.
The chip implements a full USB 2.0 device controller with internal transceiver, eliminating external PHY requirements. Its clocking architecture supports multiple internal oscillators (IMO, ILO, WCO) and external crystal inputs, enabling precise timing for both CapSense™ scanning and USB frame synchronization.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable HMI microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4247LQI-BL483 | Same core and CapSense™ engine but 128 KB flash, 16 KB SRAM, and 48-pin QFN package. | Suitable for simpler touch panels with fewer sensors and no USB connectivity. | Select when BOM cost reduction outweighs need for USB or large firmware storage. |
| STM32F072RBT6 | Arm® Cortex®-M0, 128 KB flash, 16 KB SRAM, no integrated CapSense™ - requires external touch controller or software-based solution. | Requires additional IC and firmware effort for touch functionality; better suited for non-capacitive HMI or mixed-signal control. | Choose only if existing STM32 toolchain familiarity offsets added design complexity and CapSense™ performance trade-offs. |
Compared with CY8C4248FNI-BL583T, CY8C4247LQI-BL483 reduces memory and I/O count for cost-sensitive applications, while STM32F072RBT6 shifts CapSense™ implementation burden to software and external components - making the CY8C4248FNI-BL583T optimal for integrated, production-ready touch HMI designs.

FAQ
What development tools are required to program CY8C4248FNI-BL583T?
The device is programmed using Infineon's PSoC™ Creator IDE (legacy) or ModusToolbox™ (current), both supporting full CapSense™ tuning, USB descriptor configuration, and debug via SWD interface. A KitProg3 programmer/debugger is required for flashing and real-time debugging.
Does CY8C4248FNI-BL583T support I²C or SPI master/slave operation?
Yes - it includes up to four configurable serial communication blocks (SCBs) that can be set as I²C, SPI, or UART peripherals. Each SCB supports master and slave modes, DMA-triggered transfers, and clock stretching for I²C, enabling seamless integration with displays, sensors, and EEPROMs.
Can the CapSense™ subsystem operate during deep-sleep mode?
Yes - the CapSense™ block retains autonomous operation in deep-sleep mode, scanning configured sensors and generating interrupts upon threshold crossing. Current draw remains at 1.3 µA, and wake-up latency is under 10 µs, preserving system responsiveness while minimizing power.
Is there hardware-level USB suspend/resume support?
Yes - the integrated USB controller fully complies with USB 2.0 specification, including automatic suspend detection, remote wakeup signaling, and resume synchronization. No firmware polling is needed; events trigger dedicated interrupts for low-CPU-overhead power management.
