Key Features

  • PSoC 3 architecture with 8051 CPU core and extensive programmable analog and digital peripheral blocks enabling highly customizable mixed-signal SoC designs
  • 68-pin very-thin-profile QFN (VQFN) package with exposed thermal pad supporting 260°C peak reflow for high-density PCB assembly
  • Programmable capacitive sensing (CapSense), ADCs, DACs, and programmable interconnect allowing a single chip to replace multiple discrete analog and digital ICs

Applications

The CY8C3866LTI-030 is used in industrial human-machine interface (HMI) panels, capacitive touch controllers, and smart appliances where a highly configurable mixed-signal SoC reduces external component count. It is also deployed in medical measurement instruments and portable test equipment that need flexible on-chip analog front-end configuration without redesigning hardware. Its programmable digital and analog blocks make it a strong fit for motor control, sensor signal conditioning, and custom communication protocol implementation on a single 68-pin device.

Frequently Asked Questions

What CPU core and package does the CY8C3866LTI-030 use?

The CY8C3866LTI-030 is based on the 8051 CPU core and housed in a 68-pin very-thin-profile QFN package (VQFN, 0.3-inch square body) with an exposed thermal slug. The 260°C peak reflow rating makes it compatible with standard lead-free SMT assembly processes used in consumer and industrial electronics production.

How do the programmable analog blocks in CY8C3866LTI-030 benefit sensor interface designs?

The CY8C3866LTI-030 integrates configurable analog blocks including programmable amplifiers, ADCs with up to 20-bit resolution, DACs, and comparators that can be routed to any GPIO pin. This flexibility allows designers to implement custom sensor conditioning circuits — such as bridge amplifiers, 4-20 mA input stages, or RTD interfaces — without adding external op-amps, saving 3 to 6 components per channel in multi-sensor industrial instruments.

Is the CY8C3866LTI-030 suitable for capacitive touch interface applications?

Yes. The PSoC 3 family includes Cypress CapSense technology, which enables self-capacitance and mutual-capacitance touch sensing on up to 63 sensors using the CY8C3866LTI-030. This makes it suitable for touchpad panels, slider controls, and proximity detection in home appliances, industrial HMI keyboards, and consumer electronics without requiring a separate touch controller IC.

What is the factory lead time and qualification status for the CY8C3866LTI-030 when planning a production build?

The CY8C3866LTI-030 has a 4-week factory lead time and carries a 'Not Qualified' status under formal AEC-Q100 automotive qualification, meaning it is intended for commercial and industrial applications rather than automotive-grade designs. Procurement teams should account for the 4-week lead time when placing orders for production quantities to avoid supply gaps.
