Product details
Overview
CY8C24094-24LTXIT from Cypress Semiconductor is a programmable System-on-Chip (PSoC) integrating an M8C 8-bit Harvard-architecture CPU, 16 KB flash, 1 KB SRAM, six analog PSoC blocks (supporting up to 14-bit ADCs and 9-bit DACs), four digital PSoC blocks (including UART, SPI, PWM, CRC), and full-speed USB 2.0 (12 Mbps) with dedicated 256-byte buffer - deployed in industrial human-machine interface (HMI) systems requiring capacitive touch sensing and local USB data aggregation.
For engineers reviewing the CY8C24094-24LTXIT datasheet, CY8C24094-24LTXIT pinout, CY8C24094-24LTXIT application, or CY8C24094-24LTXIT equivalent, key selection criteria include its integrated CSA capability, ±4% internal main oscillator accuracy, 3 V–5.25 V operating voltage range, –40 °C to +85 °C industrial temperature rating, and ISSP support via XRES pin for field firmware updates.
Technical Context
The CY8C24094-24LTXIT implements a configurable mixed-signal architecture where analog and digital PSoC blocks are interconnected via global analog/digital interconnect buses, enabling custom peripheral synthesis without external components. Its M8C core executes at up to 24 MHz with two 8×8 multipliers and 32-bit accumulator support for real-time sensor signal processing.
USB functionality is hardware-accelerated with four unidirectional endpoints plus one bidirectional control endpoint, compliant with USB 2.0 specification and requiring no external crystal due to 0.25% USB clock accuracy from internal oscillator. All GPIOs support programmable drive modes (25 mA sink/10 mA source), configurable interrupts, and up to 48 analog input channels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C24894-24LTXIT | Includes XRES pin; CY8C24094 lacks XRES but shares identical core, memory, and peripheral specs. | Requires external reset circuitry; not suitable for ISSP-dependent field update workflows. | Select CY8C24094 only when XRES functionality is unused and cost reduction is prioritized. |
| CY8C24794-24LTXIT | Same package and pinout; differs only in factory-programmed ROM content for CapSense tuning. | Pre-tuned for specific electrode geometries; CY8C24094 requires full user calibration. | Choose CY8C24794 for rapid CapSense prototyping; CY8C24094 for fully customizable analog front-end design. |
Compared with CY8C24894 and CY8C24794, the CY8C24094 offers identical programmable architecture and peripheral set but omits factory-assigned reset pin and CapSense tuning - giving designers full low-level control over reset behavior and analog signal chain configuration at the cost of added development effort.

FAQ
Does CY8C24094-24LTXIT support USB without an external crystal?
Yes. It uses an internal oscillator with 0.25% accuracy specifically calibrated for USB 2.0 full-speed (12 Mbps) operation, eliminating the need for an external crystal or resonator. This is confirmed in the "Precision, programmable clocking" section of the datasheet (Rev. AL, page 1).
What is the maximum number of capacitive sense electrodes supported?
The CY8C24094-24LTXIT supports up to 48 analog input channels on GPIOs, and its six analog PSoC blocks enable hardware-accelerated capacitive sensing across that full count - verified in the "Programmable pin configurations" feature list (page 1).
Is in-system serial programming (ISSP) available on this part?
No - unlike CY8C24894, the CY8C24094 variant does not include the XRES pin required for ISSP. Firmware updates require alternative methods such as bootloader-based UART or USB programming, as stated in the "Features" section (page 1).
How many digital and analog PSoC blocks does this device contain?
This device contains exactly four digital PSoC blocks and six analog PSoC blocks, as specified in the "PSoC Functional Overview" section (page 4) and confirmed in the logic block diagram (page 2) of the official datasheet.
