Product details
Overview
CY8C24293-24LQXI 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 performance, features 8 KB flash/1 KB SRAM, and supports –40 °C to +85 °C industrial temperature range - deployed in embedded control systems requiring mixed-signal integration and USB connectivity.
For engineers reviewing the CY8C24293-24LQXI datasheet, CY8C24293-24LQXI pinout, CY8C24293-24LQXI application, or CY8C24293-24LQXI equivalent, key selection criteria include USB endpoint count (9 total), GPIO count (36), low-power sleep modes (0.1 μA deep sleep), analog resources (10-bit ADC, two comparators, 8-bit IDAC), and flash endurance (50,000 erase/write cycles).
Technical Context
The CY8C24293-24LQXI implements a Harvard-architecture M8C core with dedicated instruction and data buses, enabling deterministic real-time execution. Its analog system includes a programmable analog mux, internal LDO for PSRR enhancement, and three selectable voltage references (0.8 V, 1.0 V, 1.2 V) for comparator operation.
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 eight unidirectional + one bidirectional endpoint, backed by dedicated 512-byte SRAM and crystal-free operation using the internal IMO.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | M8C Harvard architecture, 24 MHz max - enables deterministic real-time control without instruction/data bus contention. |
| Memory | 8 KB flash (50k erase/write cycles) + 1 KB SRAM - supports firmware updates and EEPROM emulation in-system. |
| USB Interface | Full-speed USB 2.0 (12 Mbps), 9 endpoints (8 uni + 1 bi), 512-byte dedicated SRAM - eliminates need for external crystal or PHY. |
| Power Modes | Deep Sleep: 0.1 μA typ; Standby: 1.1 μA typ - enables battery-powered operation for >10-year runtime in sensor nodes. |
| Analog Peripherals | 10-bit ADC (internal ref), two comparators (3 refs, 10 µA active), 8-bit IDAC (512 µA full scale) - supports precision threshold detection and analog output without external components. |
| I/O Capability | 36 GPIOs (dual-mode analog/digital), 25 mA sink per pin (120 mA total), configurable pull-up/open-drain - drives LEDs, relays, and sensors directly. |
| Clock Sources | Internal main oscillator (6/12/24 MHz), ILO (32 kHz), external 32 kHz crystal, external clock input - provides flexible timing for USB, RTC, and low-power wake-up. |
Pinout & Package
The CY8C24293-24LQXI is housed in a 48-pin QFN (7 mm × 7 mm, 0.5 mm pitch) package with exposed thermal pad. All pins support configurable drive modes (high-Z, pull-up, open-drain) and dual analog/digital functionality.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Primary power domain (1.71–5.5 V); VSS connects to thermal pad for thermal dissipation and noise reduction. |
| P0[0]–P0[7], P1[0]–P1[7], P2[0]–P2[7], P3[0]–P3[7], P4[0]–P4[3] | General-purpose I/O | 36 configurable GPIOs; ports 0–1 support 5 mA source, ports 2–4 support 1 mA source; all support analog mux routing. |
| USB_DP, USB_DM | USB differential pair | Full-speed USB 2.0 physical interface; internally terminated; requires no external transceiver or crystal. |
| XIN, XOUT | External crystal oscillator terminals | Supports optional 32 kHz crystal for precise sleep timer or RTC; not required for USB operation. |
| RESET | Active-low reset input | Asynchronous reset with internal pull-up; compatible with push-button or supervisor IC assertion. |
| SWDCK, SWDIO | Debug interface | Serial Wire Debug (SWD) pins for programming and real-time debugging via MiniProg3 or ICE-Cube. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable analog system | Programmable analog mux, internal LDO, and three precision voltage references enable sensor signal conditioning without external op-amps or references. |
| USB crystal-free operation | Internal 24 MHz IMO calibrated to ±0.25% over voltage/temperature - meets USB full-speed timing without external crystal or load capacitors. |
| Low-power sleep architecture | Deep Sleep mode retains SRAM and register state at 0.1 μA while supporting wake-up via GPIO, comparator, or timer - ideal for energy-harvesting applications. |
| Dynamic peripheral reconfiguration | User Modules (UMs) in PSoC Designer allow runtime reassignment of analog/digital blocks (e.g., repurpose comparator as window detector or ADC trigger) without firmware rewrite. |
| Integrated supervisory circuit | On-chip POR and LVD monitor VDD and assert reset if supply drops below 1.62 V (typ) - eliminates need for external reset IC in cost-sensitive designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C24493-24LQXI | 16 KB flash / 2 KB SRAM, same package and peripherals - doubles nonvolatile memory capacity. | Required when firmware exceeds 8 KB or EEPROM emulation needs >1 KB persistent storage. | Select when larger code footprint or extended data logging is needed; pin- and software-compatible. |
| CY8C24893-24LQXI | 32 KB flash / 2 KB SRAM, identical I/O and analog resources - quadruples flash vs. CY8C24293. | Suitable for complex USB class drivers (e.g., CDC ACM, MSC) or multi-protocol stacks requiring >16 KB code space. | Choose for future-proofing or when migrating from CY8C24293 with minimal hardware change. |
Compared with CY8C24293-24LQXI, the CY8C24493 offers double flash/SRAM for expanded firmware and data logging, while CY8C24893 provides quadruple flash for complex USB class implementations - both retain identical GPIO count, USB architecture, and low-power specs, enabling seamless migration within the same 48-pin QFN footprint.

FAQ
Does CY8C24293-24LQXI support USB suspend/resume without external components?
Yes. The device implements full-speed USB 2.0 with built-in transceiver, 512-byte endpoint SRAM, and crystal-free operation using its internal 24 MHz IMO. Suspend/resume is handled autonomously by the USB controller with wake-up via USB event or GPIO, requiring no external PHY, crystal, or level shifters.
What development tools are required to program and debug CY8C24293-24LQXI?
PSoC Designer™ IDE (free Windows-based tool) is mandatory for configuration and code generation. Programming and debugging require MiniProg3 or ICE-Cube hardware programmers connected via SWDCK/SWDIO pins. The CY3210-PSOCEVAL1 evaluation kit provides a ready-to-run platform with onboard MiniProg1 for rapid prototyping.
Can the internal comparators operate during Deep Sleep mode?
Yes. Both comparators remain active in Deep Sleep mode with typical current draw of 10 µA. They can generate interrupts or trigger wakeup events based on input thresholds, enabling ultra-low-power sensor monitoring - for example, detecting door-open events via magnetic reed switch without waking the CPU.
Is the 48-pin QFN package RoHS-compliant and lead-free?
Yes. The CY8C24293-24LQXI in 48-pin QFN (LQX) packaging is RoHS-compliant and lead-free, with JEDEC-standard solder reflow profile (peak 260 °C, 10-second dwell). Thermal pad must be soldered to PCB ground plane for thermal and electrical integrity, per Infineon's packaging specification document 001-86894 Rev. *D.
