CY8C20436A-24LQXIT

Product Overview

CY8C20436A-24LQXIT belongs to the Cypress Semiconductor / Infineon application-specific controller portfolio and is identified as a PSoC 1 CapSense microcontroller. It combines programmable or protocol-control logic with peripherals selected for its target system, so replacement decisions must use the complete part number.

The parameters below are limited to information located for this exact part or its directly matching base device. Values not reliably exposed in public documentation—especially for customer-programmed TrueTouch, Broadcom and legacy controller variants—are intentionally not inferred from a neighboring suffix.

In design review, CY8C20436A-24LQXIT should be treated as a programmed sensing or control subsystem rather than selected only by CPU speed or package size. Electrode or load topology, analog behavior, noise environment, host protocol, start-up state and firmware configuration can decide whether it works in the original assembly. A footprint-compatible suffix does not prove that calibration data, customer firmware or sensor tuning is transferable. Qualification should include the original configuration archive and functional testing with the production sensor or power stage.

Key Features

• Full part number: CY8C20436A-24LQXIT
• Manufacturer / historical brand: Cypress Semiconductor / Infineon
• Device type: PSoC 1 CapSense microcontroller
• M8C processor core
• PSoC 1 programmable-system architecture
• CapSense capacitive-sensing resources
• 24 MHz speed class encoded in the part number
• Flash and SRAM capacity vary by the exact CY8C20xxx member
• Program flash: 8 KB
• Shipping suffix indicates tape-and-reel on families where the manufacturer defines T as the reel option; verify reel quantity separately
• Ordering code indicates a QFN/LQFN-style surface-mount package family; confirm exact terminal count from the package drawing
• Industrial-temperature ordering grade is indicated on the researched family; confirm the complete suffix in the official ordering table

Applications

• Capacitive buttons, sliders and proximity interfaces
• Appliance and industrial user-interface panels
• Low-power embedded sensing and control

Application suitability should be confirmed against the original system requirements, including interface role, firmware revision, environmental range, package assembly process and any programmed or calibrated data. These examples describe realistic uses of the researched device family; they do not imply that every ordering suffix includes every optional peripheral or qualification grade.

Quality & Sourcing

Antrex Electronics can support sourcing review for CY8C20436A-24LQXIT, including verification of the complete ordering suffix, package, date code, packaging form and visible marking. Buyers should state the required quantity and whether blank, factory-programmed or customer-programmed material is acceptable. For programmable, secure or touch-controller devices, the firmware image, security provisioning state and customer option code can be as important as the silicon itself; Antrex Electronics does not assume that blank stock will reproduce an installed part. For obsolete or long-stored material, photos, label review, traceability checks, lead or ball inspection, solderability assessment and third-party electrical or X-ray testing can be arranged when project risk warrants them. Availability, date code and test scope remain subject to quotation and inspection.
