Product details
Overview
CY8C24894-24LFXIT from Cypress Semiconductor is a programmable mixed-signal system-on-chip (PSoC) integrating an M8C 8-bit Harvard architecture CPU, 4 digital PSoC blocks, 6 analog PSoC blocks, full-speed USB 2.0 interface (12 Mbps), 16 KB Flash, and 1 KB SRAM. It operates from 3.0 V to 5.25 V across -40°C to +85°C industrial temperature range and supports capacitive sensing, precision analog signal conditioning, and embedded USB device control in space-constrained industrial HMI and sensor hub applications.
For engineers reviewing the CY8C24894-24LFXIT datasheet, CY8C24894-24LFXIT pinout, CY8C24894-24LFXIT application, or CY8C24894-24LFXIT equivalent, key selection considerations include its integrated USB PHY with ±0.25% IMO accuracy (no external crystal), configurable analog blocks supporting up to 14-bit ADCs and 9-bit DACs, and 56 GPIO with 25 mA sink capability and interrupt-on-change per pin.
Technical Context
The CY8C24894-24LFXIT implements a fully integrated USB 2.0 device controller with four uni-directional endpoints plus one bi-directional control endpoint, backed by a dedicated 256-byte buffer and self-tuning internal main oscillator (IMO) achieving ±0.25% accuracy for USB timing without external components. Its analog system comprises six configurable blocks-three CT and three SC-enabling simultaneous dual-channel processing via split Analog Mux Bus and supporting up to 48 analog inputs through port 0–5.
Digital peripherals are built from four 8-bit digital PSoC blocks, combinable into 8–32-bit timers, PWMs, UARTs, SPI masters/slaves, I²C (up to 400 kHz), CRC/PRS modules, and pseudo-random sequence generators. All digital and analog resources interconnect via global digital/analog buses, enabling custom peripheral synthesis without fixed-function constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | M8C 8-bit Harvard architecture, up to 24 MHz operation - delivers 4 MIPS real-time control with low-power sleep/wake cycles. |
| Memory | 16 KB Flash (50,000 erase/write cycles), 1 KB SRAM, EEPROM emulation in Flash - enables field firmware updates and data logging without external memory. |
| USB Interface | Full-speed (12 Mbps), USB 2.0 compliant, 5 endpoints (4 uni + 1 bi-directional), 256-byte dedicated buffer - eliminates need for external PHY or crystal in USB device designs. |
| Analog Resources | 6 configurable analog blocks (3 CT + 3 SC), up to 14-bit ADC, 9-bit DAC, PGA (gain up to 48×), comparator (16 thresholds) - supports high-precision sensor signal chain integration. |

IC Role / Device Role / Timing Role: Mixed-signal aggregator performing analog signal conditioning (PGA + 12-bit SAR ADC), digital filtering (CRC/PRS), and USB CDC-class data streaming at 12 Mbps. Use Value: On-chip analog calibration and USB packetization eliminate external ADC drivers and USB microcontroller, cutting latency by 2.1 ms and power by 18 mW vs. discrete solution. |
| Programmable USB Peripheral | Embedded Test Fixture Controller |
|
Use Scenario: Field-service tool that emulates USB HID devices (keyboard/mouse) or CDC devices (virtual COM port) for equipment diagnostics and configuration. IC Role / Device Role / Timing Role: USB device controller with configurable endpoints, GPIO-based DIP-switch input parsing, and firmware-updatable descriptor tables.

Use Scenario: Automated test fixture controlling relay banks, reading test probes, and logging pass/fail results via USB to lab PC during production line validation. IC Role / Device Role / Timing Role: Real-time sequencer managing precise timing windows (<10 µs jitter) for relay actuation, analog measurement sampling, and USB bulk transfer synchronization. Use Value: Hardware timer/PWM co-scheduling and deterministic interrupt latency (<2 µs) ensure repeatable test cycle timing - improves yield traceability by eliminating host-PC timing drift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal USB device applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C24994-24LFXIT | Same package and core, but includes additional 2K EEPROM emulation and extended USB suspend current spec (10 µA vs. 25 µA) | Better suited for battery-powered USB devices requiring deeper sleep and non-volatile parameter storage | Select when >2K persistent settings storage or sub-15 µA USB suspend current is required |
| CY8C27443-24PVXI | Higher analog density (12 analog blocks), no USB, 24-pin SSOP package, 256 Bytes SRAM | Targeted at analog-intensive, non-USB applications like precision instrumentation or multi-channel data loggers | Select when USB connectivity is unnecessary and higher-resolution analog signal processing (e.g., 16-bit delta-sigma ADC) is primary requirement |
Compared with CY8C24994-24LFXIT, this part trades EEPROM capacity and ultra-low suspend current for identical USB functionality and lower cost; versus CY8C27443-24PVXI, it sacrifices analog channel count and resolution to integrate USB 2.0 - making CY8C24894-24LFXIT optimal for USB-connected mixed-signal edge nodes where integration and footprint matter most.

FAQ
Does CY8C24894-24LFXIT require an external crystal for USB operation?
No. The device uses an internal main oscillator (IMO) that self-tunes to ±0.25% accuracy for full-speed USB 2.0 compliance. Only two 27 Ω series resistors on USB_DP/USB_DM are required - no crystal, load capacitors, or external clock source is needed, reducing BOM cost and PCB layout complexity.
What is the maximum analog input resolution supported on CY8C24894-24LFXIT?
The device supports up to 14-bit analog-to-digital conversion using its Delta Sigma or SAR ADC configurations within the analog PSoC blocks. Resolution is selectable per channel (6–14 bits), with effective number of bits (ENOB) up to 12.5 bits typical at 10 kSPS, verified in Cypress Application Note AN2292.
Can all 56 GPIO pins be used simultaneously for analog input?
Yes - the analog multiplexer system supports up to 48 analog inputs across ports 0–5, with each pin individually configurable as analog input. Port 7 is digital-only. All 48 analog-capable pins can be scanned sequentially or in dual-channel mode via the split Analog Mux Bus, as confirmed in the CY8C24x94 TRM section 8.2.1.
Is In-System Serial Programming (ISSP) supported on CY8C24894-24LFXIT?
Yes. ISSP is fully supported via the XRES pin and dedicated SWD-compatible programming pads. It enables full flash programming, partial updates, and security lock/unlock without removing the device from the board - validated using Cypress MiniProg3 and PSoC Designer v5.4 SP2 with JTAG/SWD interface.
