Product details
Overview
CY8C24093-24LKXI from Infineon Technologies (formerly Cypress) is a PSoC® 1 programmable system-on-chip integrating an M8C CPU, configurable analog/digital peripherals, full-speed USB 2.0, and 8 KB flash/1 KB SRAM. It operates from 1.71 V to 5.5 V, supports –40 °C to +85 °C, and delivers 24 MHz max CPU speed with 0.1 μA deep sleep current. Used in embedded control systems requiring mixed-signal integration and USB connectivity.
For engineers reviewing the CY8C24093-24LKXI datasheet, CY8C24093-24LKXI pinout, CY8C24093-24LKXI application, or CY8C24093-24LKXI equivalent, key selection criteria include USB endpoint count, GPIO count (36), flash/SRAM size, low-power sleep modes, and QFN-48 package compatibility.
Technical Context
The CY8C24093-24LKXI implements a Harvard-architecture M8C core with dedicated instruction and data buses, enabling concurrent fetch and execute operations. It integrates four clock sources: 24 MHz IMO, 32 kHz ILO, external crystal, and external clock input - supporting dynamic clock switching for power optimization.
Analog resources include a 10-bit ADC with internal reference, two low-power comparators (10 µA), one 8-bit IDAC (512 µA full scale), and programmable analog mux routing. Digital resources feature three 16-bit timers, I²C slave (up to 400 kHz), SPI master/slave (up to 12 MHz), and eight unidirectional + one bidirectional USB endpoints with 512-byte dedicated SRAM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C24193-24LFXI | 16 KB flash / 2 KB SRAM; same QFN-48 package and peripheral set - higher memory for complex firmware. | Required when application exceeds 8 KB code space or needs larger data buffers. | Select when firmware complexity demands >8 KB flash; identical pinout and USB/peripheral behavior simplifies migration. |
| CY8C24493-24LFXI | 32 KB flash / 2 KB SRAM; adds OCD debug port; otherwise identical clocking, GPIO, and USB specs. | Suitable for development-intensive projects requiring on-chip debugging visibility. | Choose for prototyping or production with debug trace requirements; OCD pins occupy two GPIOs not available on CY8C24093. |

FAQ
Does CY8C24093-24LKXI require an external crystal for USB operation?
No. The device includes an internal main oscillator (IMO) calibrated to ±2% accuracy, sufficient for full-speed USB 2.0 operation without an external crystal. An external 32 kHz crystal is optional for precision RTC or ultra-low-power wake-up timing but not required for USB functionality.
What is the maximum sink current capability of the GPIOs on CY8C24093-24LKXI?
The device supports up to 25 mA sink current per GPIO pin, with a total maximum sink current of 120 mA across all GPIOs. This allows direct driving of LEDs, small relays, or logic-level MOSFET gates without external buffer transistors in most low-power control applications.
Can CY8C24093-24LKXI perform analog-to-digital conversion while in low-power mode?
Yes. The 10-bit ADC can operate in Standby mode (1.1 μA typical) using the internal 1.024 V reference. Conversion results trigger interrupts to wake the CPU, enabling periodic sensor sampling with minimal average power consumption - ideal for battery-operated monitoring systems.
Is PSoC Designer™ still supported for CY8C24093-24LKXI development?
Yes. PSoC Designer™ v5.4 remains the official IDE for CY8C24093-24LKXI, providing drag-and-drop analog/digital peripheral configuration, automatic API generation, and ISSP-based programming. Infineon maintains legacy tool support and documentation for this device family through its PSoC 1 resource portal.
