Product details
Overview
CY8C5868LTI-LP038 from Infineon Technologies (formerly Cypress) is a 32-bit Arm Cortex-M3–based programmable system-on-chip (PSoC® 5LP) integrating configurable analog/digital peripherals, 256 KB flash, 64 KB RAM, and full-speed USB 2.0 interface. It operates from 1.71–5.5 V across –40 to 85 °C, supports CapSense® up to 62 sensors, and delivers ultra-low-power operation with 300-nA hibernate mode. Used in embedded human-interface and sensor-fusion applications requiring mixed-signal integration and field-programmable logic.
For engineers reviewing the CY8C5868LTI-LP038 datasheet, CY8C5868LTI-LP038 pinout, CY8C5868LTI-LP038 application, or CY8C5868LTI-LP038 equivalent, key selection criteria include its 68-pin QFN package, dual 12-bit SAR ADCs, full CAN 2.0b support (16 Rx/8 Tx), DFB-based digital filtering, and flexible UDB-based peripheral synthesis - all critical for low-power industrial control and touch-enabled edge devices.
Technical Context
The CY8C5868LTI-LP038 implements a tightly coupled architecture where the Arm Cortex-M3 core (up to 80 MHz) interfaces directly with a 24-channel DMA controller and a dedicated 24-bit 64-tap digital filter processor (DFB). Its routing fabric enables any analog or digital peripheral function-including I²C, SPI, UART, PWM, and custom logic-to be assigned to any of 62 GPIOs via the Digital System Interconnect (DSI).
Analog subsystem flexibility includes four opamps, four comparators, four 8-bit DACs, and programmable SC/CT blocks supporting PGA, TIA, and mixer configurations. The device integrates two independent 12-bit SAR ADCs (1 Msps max) and one delta-sigma ADC (up to 20-bit resolution), all referenced to a 1.024 V ±0.1% internal voltage reference.

FAQ
Is CY8C5868LTI-LP038 pin-compatible with other CY8C58LP devices?
Yes - all CY8C58LP variants sharing the 68-pin QFN package (e.g., CY8C5868LTI-LP039, CY8C5868LTI-LP040) use identical pinouts and mechanical footprint. Electrical differences (e.g., flash size, temperature grade) do not affect physical compatibility or PCB layout reuse.
Does CY8C5868LTI-LP038 require an external crystal for USB operation?
No - the device uses its internal IMO (internal main oscillator) calibrated to ±1% at 3 MHz, which feeds the USB PLL to generate the precise 48 MHz clock required for full-speed USB. An external crystal is optional and only needed if tighter frequency stability (<±0.25%) is required for concurrent CAN/USB timing.
Can CapSense® operate while the device is in hibernate mode?
Yes - CapSense® supports wake-on-touch from hibernate mode using the low-power ILO (100 kHz) and dedicated hardware scanning engine. Only the CapSense® block and associated GPIOs remain powered; CPU, flash, and most peripherals stay off until touch event triggers wake-up interrupt.
What debug interfaces does CY8C5868LTI-LP038 support?
It supports JTAG (4-wire), SWD (2-wire), SWV (single-wire viewer), and TracePort (5-wire) interfaces. All are accessible via standard ARM-compliant debug probes (e.g., Segger J-Link, ST-Link v2), and PSoC Creator IDE provides full firmware download, breakpoint, and real-time variable inspection capabilities.
