Product details
Overview
CY8C3865LTI-062 from Cypress Semiconductor is a programmable system-on-chip (PSoC® 3) integrating an 8051 CPU core, up to 64 KB flash, 8 KB SRAM, 2 KB EEPROM, 24-channel DMA, and configurable analog/digital peripherals including a 20-bit delta-sigma ADC (192 ksps), four opamps, four comparators, and full CAN 2.0b interface - deployed in industrial sensor nodes and embedded control systems requiring mixed-signal flexibility and firmware-upgradable functionality.
For engineers reviewing the CY8C3865LTI-062 datasheet, CY8C3865LTI-062 pinout, CY8C3865LTI-062 application, or CY8C3865LTI-062 equivalent, key selection criteria include its 62 GPIOs with analog routing capability, 67 MHz CPU clock, –40°C to +85°C industrial temperature range, 48-pin SSOP package, and support for CapSense®, USB 2.0 FS, and programmable digital logic via UDB array.
Technical Context
The CY8C3865LTI-062 implements a single-cycle 8051 microcontroller core with AMBA AHB bus architecture, supporting up to 67 MHz operation and hardware multiply/divide instructions. Its digital subsystem centers on 24 universal digital blocks (UDBs) enabling user-defined logic, timers, PWMs, UARTs, I²C, LIN, and quadrature decoding without external components.
Analog signal processing is anchored by a 20-bit delta-sigma ADC (192 ksps at 12-bit, 48 ksps at 16-bit), 1.024 V ±0.1% internal reference, four rail-to-rail opamps (25 mA drive), and a 24-bit DFB for real-time FIR/IIR filtering - all accessible through fully routable analog interconnect to any of 62 GPIOs.

FAQ
Does CY8C3865LTI-062 support USB device enumeration without external crystal?
Yes. It integrates a full-speed USB 2.0 PHY and uses its internal 48 MHz IMO (Internal Main Oscillator) for USB clocking, eliminating the need for an external 48 MHz crystal or oscillator in standard USB device implementations.
What is the maximum operating frequency of the delta-sigma ADC in 16-bit mode?
In 16-bit mode, the delta-sigma ADC achieves a maximum sample rate of 48 ksps with 84 dB SINAD and ±2 LSB INL - verified per the CY8C38 Family Datasheet Rev. *Q, Section 8.2, under VDDA = 3.3 V and TA = 25°C.
Can all 62 GPIOs be used simultaneously for analog input acquisition?
No. While all 62 GPIOs are analog-capable and routable to the ADC input mux, the delta-sigma ADC has a single conversion channel; simultaneous multi-channel sampling requires time-multiplexed sequencing via firmware-controlled channel switching and DMA triggers.
Is the CAN interface compliant with ISO 11898-1:2015?
Yes. The integrated CAN 2.0b controller supports all mandatory features of ISO 11898-1:2015, including bit timing configuration, error frame generation, and automatic retransmission - but requires an external CAN transceiver (e.g., TJA1042) for physical layer compliance.
