Infineon Technologies CY8C240093-24LTXI

Overview

CY8C240093-24LTXI 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 up to 36 GPIOs in a 48-pin QFN package. It operates from 1.71 V to 5.5 V, delivers 24 MHz CPU performance, features 8 KB flash/1 KB SRAM, and supports –40 °C to +85 °C industrial temperature range - enabling compact embedded control with integrated USB connectivity in space-constrained industrial sensors.

For engineers reviewing the CY8C240093-24LTXI datasheet, CY8C240093-24LTXI pinout, CY8C240093-24LTXI application, or CY8C240093-24LTXI equivalent, key selection criteria include USB endpoint count (8 unidirectional + 1 bidirectional), low-power sleep modes (0.1 μA deep sleep), GPIO sink capability (25 mA per pin), and on-chip 10-bit ADC with internal voltage reference - all critical for USB-enabled sensor node and programmable I/O controller designs.

Technical Context

The CY8C240093-24LTXI implements a Harvard-architecture M8C core with dedicated instruction and data buses, supporting deterministic real-time execution. Its analog system includes two comparators with selectable 0.8 V/1.0 V/1.2 V references, a 10-bit incremental ADC, and an 8-bit IDAC (512 µA full scale), all routed via global analog interconnect.

Digital resources include three 16-bit programmable timers, I²C slave (up to 400 kHz), SPI master/slave (up to 12 MHz), and a full-speed USB 2.0 interface with dedicated 512-byte SRAM and no external crystal requirement - enabled by internal 6/12/24 MHz IMO and 32 kHz ILO clock sources.

FAQ

Does CY8C240093-24LTXI require an external crystal for USB operation?

No. The device integrates an internal main oscillator (IMO) that can be trimmed to ±0.25% accuracy, meeting USB full-speed timing requirements without an external crystal. The 32 kHz crystal input is optional and used only for high-precision RTC or low-jitter wake-up timing.

What development tools support CY8C240093-24LTXI firmware creation and debug?

PSoC Designer™ IDE (free Windows-based tool) is the official development environment, providing drag-and-drop peripheral configuration, API code generation, and hardware debugging via MiniProg3 or ICE-Cube programmers. The CY3210-PSOCEVAL1 evaluation kit includes a pre-programmed board for rapid prototyping.

Can CY8C240093-24LTXI operate reliably at 5.5 V supply with all GPIOs driving 25 mA simultaneously?

No. While each GPIO supports 25 mA sink individually, the absolute maximum total sink current across all GPIOs is 120 mA. At 5.5 V, power dissipation and voltage drop must be verified per application; simultaneous full-load operation requires careful thermal design and current limiting per port.

Is the 10-bit ADC on CY8C240093-24LTXI usable with external sensors requiring ratiometric measurement?

Yes. The ADC supports external reference input via the VREF pin and internal references (1.0 V, 1.2 V). When paired with a precision external voltage reference or resistor-divider network, it achieves ratiometric accuracy for bridge sensors, RTDs, or potentiometers without additional signal conditioning ICs.
